Note 1. Description of Business and Summary of Significant Accounting Policies

Description of Business

Lumentum Holdings Inc. (“we,” “us,” “our”, “Lumentum” or the “Company”) is an industry-leading provider of optical and photonic products defined by revenue and market share addressing a range of end market applications including Optical Communications (“OpComms”) and Commercial Lasers (“Lasers”) for manufacturing, inspection and life-science applications. We seek to use our core optical and photonic technology, and our volume manufacturing capability, to expand into attractive emerging markets that benefit from advantages that optical or photonics-based solutions provide, including 3D sensing for consumer electronics and diode light sources for a variety of consumer and industrial applications. The majority of our customers tend to be original equipment manufacturers (“OEMs”) that incorporate our products into their products which then address end-market applications. For example, we sell fiber optic components that network equipment manufacturers (“NEMs”) assemble into communications networking systems, which they sell to network service providers, operators or enterprises with their own networks. Similarly, many of our customers for our Lasers products incorporate our products into tools they produce, which are used for manufacturing processes by their customers. For 3D sensing, we sell diode lasers to manufacturers of consumer electronics products for mobile, personal computing, gaming, and other applications who then integrate our devices within their products, for eventual resale to consumers and also into other industrial applications.

Basis of Presentation

The preparation of the condensed consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results may be different from the estimates. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are inventory valuation, revenue recognition, income taxes, and goodwill.

The COVID-19 pandemic has created and may continue to create significant uncertainty in global financial markets, which has disrupted and harmed, and may continue to disrupt and harm, the Company's business, financial condition, and results of operations. The extent of the impact of COVID-19 on the Company's operational and financial performance will depend on certain developments, including but not limited to the duration and spread of the outbreak, duration of local, state and federal issued public health orders in each jurisdiction where we operate or in which our customers and suppliers operate, impact on our customers and our sales cycles, impact on our supply chain and manufacturing partners, impact on our employees and impact on regional and worldwide economies and financial markets in general, all of which are uncertain and cannot be predicted.

Termination of Coherent Merger Agreement

On January 18, 2021, Lumentum and Coherent, Inc. (“Coherent”) entered into a merger agreement (the “merger agreement”), under which Lumentum would acquire all outstanding shares of Coherent common stock. As of the date of the merger agreement, the total transaction consideration was approximately $5.7 billion. In March 2021, Coherent terminated the merger agreement and paid Lumentum a termination fee of $217.6 million in accordance with the merger agreement. This gain was offset by $10.1 million of acquisition related expenses and the net amount is presented as “merger termination fee and related costs, net” in our condensed consolidated statements of operations for the three and nine months ended April 3, 2021.

Fiscal Years

We utilize a 52-53 week fiscal year ending on the Saturday closest to June 30th. Every fifth or sixth fiscal year will have a 53-week period. The additional week in a 53-week year is added to the third quarter, making such quarter consist of 14 weeks. Our fiscal 2021 is a 53-week year ending on July 3, 2021, with the quarter ended April 3, 2021 being a 14-week quarterly period. Our fiscal 2020 was a 52-week year that ended on June 27, 2020, with the quarter ended March 28, 2020 being a 13-week quarterly period.

Principles of Consolidation

These interim unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

Accounting Policies

The accompanying condensed consolidated financial statements and accompanying related notes should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended June 27, 2020. There have been no significant changes to these policies during the nine months ended April 3, 2021, except for the removal of the long-lived asset valuation policy and the updates resulting from the adoption of Topic 326, as discussed in “Note 2. Recently Issued Accounting Pronouncements”.

Note 2. Recently Issued Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on transfers between Level 1 and Level 2, valuation processes of Level 3 fair value measurements, and the categorization by level for items that are not measured at fair value, but for which the fair value is required to be disclosed. We adopted ASU 2018-13 in the first quarter of fiscal 2021 with no impact to our condensed consolidated financial statements.

In August 2018, FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This standard requires capitalization of the implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Further, the standard also requires the Company to expense the capitalized implementation costs of a hosting arrangement over the term of the hosting arrangement. We adopted ASU 2018-15 in the first quarter of fiscal 2021 with no impact to our condensed consolidated financial statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and a subsequent amendment, ASU 2018-19 (collectively, Topic 326). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. We adopted ASU 2016-13 using the modified-retrospective approach in the first quarter of fiscal 2021 with no material impact to our condensed consolidated financial statements.

With the adoption of Topic 326, we are now assessing whether unrealized losses have resulted from a credit loss or other factors. We believe none of our unrealized losses on available-for-sale investments were other-than temporary or were attributable to credit losses as of April 3, 2021 and June 27, 2020. We review our available-for-sale investments on a quarterly basis to identify a potential other-than-temporary impairment. The investments with unrealized losses consisted primarily of corporate debt securities, and given the extent of the unrealized loss positions, the issuers' high credit ratings and the near-term market conditions, we believe our unrealized losses are temporary. We also do not have an intent to sell our investments and would not be required to sell them before they recover.

The adoption of Topic 326 did not significantly change our approach to the valuation of trade receivables. We determine whether there is an expected loss on our accounts receivable by reviewing all available data, including our customers' latest available financial statements, their credit standing and historical collection experience, as well as current and future market and economic conditions. As of April 3, 2021 and June 27, 2020, the allowance for credit losses on our trade receivables was $1.8 million and $1.8 million, respectively.

Accounting Pronouncements Not Yet Effective

In August 2020, FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for convertible instruments by removing the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. As a result, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost. Also, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and the treasury stock method will be no longer available. The new guidance is effective for fiscal years beginning after December 15, 2021, with early adoption permitted no earlier than fiscal years beginning after December 15, 2020. ASU 2020-06 is effective for us in our first quarter of fiscal year 2023. We are currently evaluating the impact of ASU 2020-06 on our condensed consolidated financial statements.

In December 2019, FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), which is intended to simplify various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and which also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for us at the beginning of fiscal year 2022, including interim periods within that reporting period, although early adoption is permitted. We are currently evaluating the impact of ASU 2019-12 on our condensed consolidated financial statements.

In August 2018, FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Topic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies the disclosure requirements for defined benefit pension plans and other post-retirement benefit plans. The new guidance is effective for fiscal years ending after December 15, 2020, with early adoption permitted. ASU 2018-14 should be applied retrospectively to all periods presented and is effective for us in our fourth quarter of fiscal year 2021 as ASU 2018-14 does not amend the interim disclosure requirements. We are currently evaluating the impact of ASU 2018-14 on our condensed consolidated financial statements.

Note 3. Earnings Per Share

The following table sets forth the computation of basic and diluted net income per share (in millions, except per share data):

	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020
Numerator:
Net income	$	225.5	$	43.4	$	375.8	$	140.1
Denominator:
Basic weighted average common shares outstanding	75.8		74.8		75.6		76.2
Effect of dilutive securities from stock-based benefit plans	0.8		1.0		0.8		0.8
Shares issuable assuming conversion of the 2024 Notes	2.6		1.7		2.2		0.7
Diluted weighted average common shares outstanding	79.2		77.5		78.6		77.7
Net income per share:
Basic	$	2.97	$	0.58	$	4.97	$	1.84
Diluted	$	2.85	$	0.56	$	4.78	$	1.80

Potentially dilutive common shares result from the assumed exercise of outstanding stock options, assumed vesting of outstanding equity awards, assumed issuance of stock under the employee stock purchase plan, and assumed conversion of our outstanding convertible notes, all using the treasury stock method.

We have the ability and intent to settle the face value of our convertible notes in cash. Therefore, we use the treasury stock method for calculating the dilutive impact of the convertible notes. The 2026 Notes (as defined in Note 9) will have no impact on diluted earnings per share until the average price of our common stock exceeds the conversion price of $99.29. The potentially dilutive shares resulting from the 2024 Notes (as defined in Note 9) were included in the calculation of diluted income per share for the three and nine months ended April 3, 2021 since the average price of our common stock exceeded the conversion price of $60.62. Refer to “Note 9. Debt” for further discussion.

Anti-dilutive potential shares are excluded from the calculation of diluted earnings per share if their exercise price exceeded the average market price during the period or the share-based awards were determined to be anti-dilutive based on applying the treasury stock method. Anti-dilutive shares excluded from the calculation of diluted earnings per share were not material and were 0.5 million shares for the three and nine months ended April 3, 2021, respectively. Anti-dilutive shares excluded from the calculation of diluted earnings per share were not material for each of the three and nine months ended March 28, 2020, respectively.

All available-for-sale securities have been classified as current, based on management’s intent and ability to use the funds in current operations.

Note 5. Fair Value Measurements

We determine fair value based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value:

13

LUMENTUM HOLDINGS INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

Level 1:	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2:	Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.
Level 3:	Inputs are unobservable inputs based on our assumptions.

The fair value of our Level 1 financial instruments, such as money market funds and U.S. Treasury securities, which are traded in active markets, is based on quoted market prices for identical instruments. The fair value of our Level 2 fixed income securities is obtained from an independent pricing service, which may use quoted market prices for identical or comparable instruments or model driven valuations using observable market data or inputs corroborated by observable market data. Our marketable securities are held by custodians who obtain investment prices from a third-party pricing provider that incorporates standard inputs in various asset price models. Our procedures include controls to ensure that appropriate fair values are recorded, including comparing the fair values obtained from our pricing service against fair values obtained from another independent source.

Financial Instruments Not Recorded at Fair Value on a Recurring Basis

We report our financial instruments at fair value with the exception of the 2026 Notes and the 2024 Notes. The estimated fair value of the notes was determined based on the trading price of the notes as of the last day of trading for the period. We consider the fair value of the notes to be a Level 2 measurement as they are not actively traded in markets.

The carrying amounts and estimated fair values of the 2026 Notes and the 2024 Notes are as follows for the periods presented (in millions):

	April 3, 2021				June 27, 2020
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
2026 Notes	$	778.9	$	1,240.5	$	749.7	$	1,070.2
2024 Notes	385.3		730.9		370.6		620.0
	$	1,164.2	$	1,971.4	$	1,120.3	$	1,690.2

Assets Measured at Fair Value on a Non-Recurring Basis

We periodically review our intangible and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and its eventual disposition. If not recoverable, an impairment loss would be calculated based on the excess of the carrying amount over the fair value.

Management utilizes various valuation methods, including an income approach, a market approach and a cost approach, to estimate the fair value of intangibles and other long-lived assets. During the annual impairment testing performed in the fourth quarter of fiscal 2020, we concluded that our intangible and other long-lived assets were not impaired. We review our intangible and other long-lived assets for impairment at least annually in the fourth quarter of each fiscal year, absent any interim indicators of impairment.

Note 6. Balance Sheet Details

Allowance for current expected credit losses

We did not have any allowance for credit losses other than our allowance for uncollectible accounts receivable. As of April 3, 2021 and June 27, 2020, the allowance for credit losses on our trade receivables was $1.8 million and $1.8 million, respectively.

Note 7. Leases

We lease certain real and personal property from unrelated third parties under non-cancellable operating leases that expire at various dates through fiscal 2033. These operating leases are mainly for administrative offices, research-and-development and manufacturing facilities, as well as sales offices in various countries around the world. Certain leases require us to pay property taxes, insurance and routine maintenance, and include escalation clauses. Many leases include one or more options to renew. We do not assume renewals in our determination of the lease term unless the renewals are deemed to be reasonably assured at lease commencement.

We also have various finance leases of servers and certain other equipment for our operations. These arrangements are typically for two to four years.

As of April 3, 2021, we sublease certain floors of our offices in the United Kingdom, the United States, Canada, and Japan. These subleases will expire at various dates by fiscal year 2023. We anticipate receiving approximately $3.6 million in sublease income over the next two years.

Impairment of Goodwill

We review goodwill for impairment during the fourth quarter of each fiscal year or more frequently if events or circumstances indicate that an impairment loss may have occurred. In the fourth quarter of fiscal 2020, we completed the annual impairment test of goodwill, which indicated there was no goodwill impairment. There were no indicators of goodwill impairment during the three and nine months ended April 3, 2021.

Other Intangibles

The intangible assets are amortized on a straight-line basis over the estimated useful lives, except for customer relationships and order backlog, which are amortized using an accelerated method of amortization over the expected customer lives, which more accurately reflects the pattern of realization of economic benefits expected to be obtained. Acquired developed technologies and order backlog are amortized to cost of sales and customer relationships is amortized to selling, general and administrative. In-process research and development (“IPR&D”) is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. When an IPR&D project is completed, the IPR&D is reclassified as an amortizable purchased intangible asset and amortized over the asset’s estimated useful life.

The following tables present details of our other intangibles as of the periods presented (in millions, except for weighted average remaining amortization period):

April 3, 2021	Gross Carrying Amounts		Accumulated Amortization		Net Carrying Amounts		Weighted average remaining amortization period (years)
Acquired developed technologies	$	390.3	$	(222.3)	$	168.0	3.2

The table above excludes fully amortized intangibles of $5.5 million that were written off against accumulated amortization during the three and nine months ended April 3, 2021.

During the three and nine months ended April 3, 2021, we completed our remaining IPR&D projects and therefore reclassified $10 million from IPR&D to acquired developed technologies. This amount will be amortized over the assets’ estimated useful life of 3 years.

During the nine months ended April 3, 2021, we purchased intellectual property from a third party for a total consideration of $10 million. These intangible assets have an estimated useful life of 5 years.

June 27, 2020	Gross Carrying Amounts		Accumulated Amortization		Net Carrying Amounts		Weighted average remaining amortization period (years)

Note 9. Debt

Convertible Notes

2026 Notes

In December 2019, we issued $1,050 million in aggregate principal amount of the 2026 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The 2026 Notes are governed by an indenture between the Company and U.S. Bank National Association (the “2026 Indenture”). We used approximately $196 million of the net proceeds of the offering to repay in full all amounts outstanding under our term loan credit facility, and a portion of the net proceeds of the offering to purchase approximately $200 million of our common stock concurrently with the pricing of the offering in privately negotiated transactions. The 2026 Notes are unsecured and do not contain any financial covenants, restrictions on dividends, incurrence of senior debt or other indebtedness, or the issuance or repurchase of securities by us.

The 2026 Notes will bear interest at a rate of 0.50% per year, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2020. The 2026 Notes will mature on December 15, 2026, unless earlier redeemed, repurchased by us, or converted pursuant to their terms.

The initial conversion rate is 10.0711 shares of common stock per $1,000 principal amount of the 2026 Notes (which is equivalent to an initial conversion price of approximately $99.29 per share). The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, upon the occurrence of a make-whole fundamental change or our issuance of a notice of redemption, we will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert the 2026 Notes in connection with such make-whole fundamental change or notice of redemption.

Prior to the close of business on the business day immediately preceding September 15, 2026, holders of the 2026 Notes may convert their 2026 Notes only under certain circumstances discussed in detail in our Annual Report on Form 10-K for the year ended June 27, 2020.

2024 Notes

In March 2017, we issued $450 million of the 2024 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 2024 Notes are governed by an indenture between the Company, as the issuer, and U.S. Bank National Association, as trustee (the “2024 Indenture”). The 2024 Notes are unsecured and do not contain any financial covenants, restrictions on dividends, incurrence of senior debt or other indebtedness, or the issuance or repurchase of securities by us.

The 2024 Notes bear interest at a rate of 0.25% per year. Interest on the 2024 Notes is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2017. The 2024 Notes will mature on March 15, 2024, unless earlier repurchased by us or converted pursuant to their terms.

The initial conversion rate of the 2024 Notes is 16.4965 shares of common stock per $1,000 principal amount of 2024 Notes, which is equivalent to an initial conversion price of approximately $60.62 per share, a 132.5% premium to the fair market value at the date of issuance. Prior to the close of business on the business day immediately preceding December 15, 2023, each holder of the 2024 Notes may convert their 2024 Notes only under certain circumstances discussed in detail in our Annual Report on Form 10-K for the year ended June 27, 2020.

Our convertible notes consisted of the following components as of the periods presented (in millions):

Liability component:	April 3, 2021				June 27, 2020
	2024 Notes (1)		2026 Notes		2024 Notes (1)		2026 Notes
Principal	$	450.0	$	1,050.0	$	450.0	$	1,050.0
Unamortized debt discount and debt issuance costs	(64.7)		(271.1)		(79.4)		(300.3)
Net carrying amount of the liability component	$	385.3	$	778.9	$	370.6	$	749.7

(1) Since the closing price of our stock exceeded $78.80 (or 130% of the conversion price of $60.62) for 20 of the last 30 trading days of the third quarter of fiscal 2021, the 2024 Notes have become convertible at the option of the holders. Therefore, the debt component of our 2024 Notes as of April 3, 2021 has been classified as current liabilities in our condensed consolidated balance sheet.

If the closing price of our stock exceeds $129.08 (or 130% of the conversion price of $99.29) for 20 of the last 30 trading days of any future quarter, our 2026 Notes would also become convertible at the option of the holders and the debt component would be reclassified to current liabilities in our condensed consolidated balance sheet.

The following table sets forth interest expense information related to the convertible notes for the periods presented (in millions):

	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020
Contractual interest expense	$	1.6	$	1.6	$	4.8	$	2.3
Amortization of the debt discount and debt issuance costs	14.8		14.0		43.9		24.8
Total interest expense	$	16.4	$	15.6	$	48.7	$	27.1

The future interest and principal payments related to our convertible notes are as follows as of April 3, 2021 (in millions):

The principal balances of our Notes are reflected in the payment periods in the table above based on their respective contractual maturities. During the three and nine months ended April 3, 2021, we received conversion requests for less than $0.1 million principal amount of the 2024 Notes, which will be settled in cash in the fourth quarter of fiscal 2021.

Term Loan Facility

In December 2018, concurrent with the closing of the Oclaro merger, we entered into a credit agreement providing for a term loan facility (the “Term Loan Facility”) in an aggregate principal amount of $500.0 million and we drew in full the term loans available under the Term Loan Facility on the closing date of the Oclaro merger. In the second quarter of fiscal 2020, we repaid, in full, all amounts outstanding under our Term Loan Facility. During the nine months ended March 28, 2020, we incurred $18.1 million of interest expense on this Term Loan Facility, which includes an $8.0 million loss on the early extinguishment of debt.

Other Interest Expense

For the nine months ended March 28, 2020, we also recorded $0.1 million interest expense related to our finance leases.

Note 10. Accumulated Other Comprehensive Income (Loss)

Our accumulated other comprehensive income (loss) consists of the accumulated net unrealized gains or losses on foreign currency translation adjustments, the defined benefit obligations, and available-for-sale securities.

The changes in accumulated other comprehensive income (loss) were as follows for the periods as presented (in millions):

	Foreign currency translation adjustments, net of tax (1)		Defined benefit obligations, net of tax (2)		Unrealized gain (loss) on available-for-sale securities, net of tax (3)		Total

(1) In fiscal 2019, as a result of significant changes in economic facts and circumstances, primarily due to the acquisition of Oclaro, we established the functional currency for our worldwide operations as the U.S. dollar. Translation adjustments reported prior to December 10, 2018, remain as a component of accumulated other comprehensive income in our condensed consolidated balance sheets, until all or a part of the investment in the subsidiaries is sold or liquidated.

(2) We evaluate the assumptions over the fair value of our defined benefit obligations annually and make changes as necessary.

(3) Unrealized loss on available-for-sale securities for the three and nine months ended April 3, 2021 is presented net of tax of $0.1 million and $0.6 million, respectively. Tax impact was not material for the other periods presented.

Note 11. Restructuring and Related Charges

We have initiated various strategic restructuring actions primarily intended to reduce costs, consolidate our operations, rationalize the manufacturing of our products and align our business in response to market conditions.

The following table summarizes the activity of restructuring and related charges during the three and nine months ended April 3, 2021 and March 28, 2020 (in millions):

	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020
Balance as of beginning of period	$	4.6	$	5.0	$	5.2	$	14.6
Charges	2.9		2.7		3.1		4.9
Payments	(3.3)		(5.1)		(4.1)		(16.9)
Balance as of end of period	$	4.2	$	2.6	$	4.2	$	2.6

During the three and nine months ended April 3, 2021, we recorded restructuring and related charges of $2.9 million and $3.1 million, respectively, in our condensed consolidated statements of operations. The charges were mainly attributable to severance charges associated with the decision to cease manufacturing of certain products in San Jose, California.

During the three and nine months ended March 28, 2020, we recorded $2.7 million and $4.9 million, respectively, in restructuring and related charges in our condensed consolidated statements of operations. The charges were mainly attributable to severance charges associated with the decision to move certain manufacturing from San Jose, California to our facility in Thailand and other third party vendors.

Any changes in the estimates of executing our restructuring activities will be reflected in our future results of operations.

Note 12. Income Taxes

Our tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, we update our estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, we make a cumulative adjustment in such period. Our quarterly tax provision and estimate of our annual effective tax rate are subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income relates, changes in how we do business, and tax law developments.

We recorded a tax provision of $27.4 million and $58.8 million for the three and nine months ended April 3, 2021, respectively. Our tax provision for the three months ended April 3, 2021 includes a discrete tax expense of $16.8 million mainly associated with the Coherent termination fee, partially offset by currency re-measurement of certain tax related accounts and return-to-provision differences. Our estimated effective tax rate for fiscal 2021 differs from the 21% U.S. statutory rate primarily due to the earnings of our foreign subsidiaries being taxed at rates that differ from the U.S. statutory rate as well as the U.S. federal R&D tax credits, partially offset by the income tax expense from non-deductible stock-based compensation and the tax effect of Global Intangible Low-Taxed Income (“GILTI”), net of benefit for foreign tax credits, and subpart F inclusion.

As of April 3, 2021, we had $26.9 million of unrecognized tax benefits, which, if recognized, would affect the effective tax rate. We are subject to examination of income tax returns by various domestic and foreign tax authorities. The timing of commencement, resolution and closure of tax audits is highly unpredictable. Although it is possible that certain ongoing tax audits may be concluded within the next 12 months, we cannot reasonably estimate the impact to tax expense and net income from tax exams that could be resolved or closed within the next 12 months. Subject to audit timing and uncertainty, we expect our unrecognized tax benefit amount that could affect the effective tax rate to decrease by $4.8 million over the next 12 months.

We believe that we have adequately provided under GAAP for potential outcomes related to our tax audits. However, there can be no assurances as to the possible outcomes or any related financial statement effect thereof.

Note 13. Equity

Description of Lumentum Stock-Based Benefit Plans

Equity Incentive Plan

As of April 3, 2021, we had 2.2 million shares subject to restricted stock units and performance stock units issued and outstanding under the 2015 Equity Incentive Plan (the “2015 Plan”). Restricted stock units and performance stock units are performance-based, time-based or a combination of both. The fair value of these grants is based on the closing market price of our common stock on the date of award.

As of April 3, 2021, 2.3 million shares of common stock under the 2015 Plan were available for grant.

Replacement Awards

In connection with the acquisition of Oclaro, we issued equity awards to Oclaro employees (“replacement awards”) in exchange for their Oclaro equity awards. As of April 3, 2021, we had 0.1 million of unvested shares subject to restricted stock units under the replacement awards.

Restricted Stock Units

Restricted stock units (“RSUs”) under the 2015 Plan are grants of shares of our common stock, the vesting of which is based on the requisite service requirement. Generally, our RSUs are subject to forfeiture and are expected to vest over one to four years. For annual refresh grants, RSUs generally vest ratably on an annual, or combination of annual and quarterly, basis over three years.

Performance Stock Units

Performance stock units (“PSUs”) under the 2015 Plan are grants of shares of our common stock that vest upon the achievement of certain performance and service conditions. We begin recognizing compensation expense when we conclude that it is probable that the performance conditions will be achieved. We reassess the probability of vesting at each reporting period and adjust our compensation cost based on this probability assessment. Our PSUs are subject to risk of forfeiture until performance and service conditions are satisfied and generally vest over three years.

Employee Stock Purchase Plan

Our 2015 Employee Stock Purchase Plan (the “2015 Purchase Plan”) provides eligible employees with the opportunity to acquire an ownership interest in the Company through periodic payroll deductions and provides a 15% purchase price discount as well as a 6-month look-back period. The 2015 Purchase Plan is structured as a qualified employee stock purchase plan under Section 423 of the Internal Revenue Code of 1986, as amended. The 2015 Purchase Plan will terminate upon the date on which all shares available for issuance have been sold. Of the 3.0 million shares authorized under the 2015 Purchase Plan, 1.7 million shares remained available for issuance as of April 3, 2021.

Stock-Based Compensation

The impact on our results of operations of recording stock-based compensation by function for the three and nine months ended April 3, 2021 and March 28, 2020 was as follows (in millions):

	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020
Cost of sales	$	5.3	$	4.3	$	13.8	$	12.6
Research and development	5.3		4.2		14.8		12.1
Selling, general and administrative	14.5		10.7		40.1		31.4

Canceled	(0.1)	64.1		—	70.8
Balance as of April 3, 2021	2.0	$	74.1	0.3	$	74.4

As of April 3, 2021, $147.2 million of stock-based compensation cost related to awards granted to our employees remains to be amortized. That cost is expected to be recognized over an estimated amortization period of 1.9 years.

A summary of awards available for grant is as follows (in millions):

	Awards Available for Grant
Balance as of June 27, 2020	3.5
Granted	(1.3)
Canceled	0.1
Balance as of April 3, 2021	2.3

Employee Stock Purchase Plan Activity

The 2015 Purchase Plan expense for the three months ended April 3, 2021 and March 28, 2020 was $1.2 million and $0.8 million, respectively. The 2015 Purchase Plan expense for the nine months ended April 3, 2021 and March 28, 2020 was $3.5 million and $2.5 million, respectively. The expense related to the 2015 Purchase Plan is recorded on a straight-line basis over the relevant subscription period. During the three and nine months ended April 3, 2021, there were 0.1 million shares issued to employees through the 2015 Purchase Plan.

Note 14. Commitments and Contingencies

Purchase Obligations

Purchase obligations of $224.9 million as of April 3, 2021, represent legally-binding commitments to purchase inventory and other commitments made in the normal course of business to meet operational requirements.

Although open purchase orders are considered enforceable and legally binding, the terms generally allow the option to cancel, reschedule and adjust the requirements based on our business needs prior to the delivery of goods or performance of services. Obligations to purchase inventory and other commitments are generally expected to be fulfilled within one year.

LUMENTUM HOLDINGS INC.

We depend on a limited number of contract manufacturers, subcontractors and suppliers for raw materials, packages and standard components. We generally purchase these single or limited source products through standard purchase orders or one-year supply agreements and have no significant long-term guaranteed supply agreements with such vendors. While we seek to maintain a sufficient safety stock of such products and maintain on-going communications with our suppliers to guard against interruptions or cessation of supply, our business and results of operations could be adversely affected by a stoppage or delay of supply, substitution of more expensive or less reliable products, receipt of defective parts or contaminated materials, increases in the price of such supplies, or our inability to obtain reduced pricing from our suppliers in response to competitive pressures.

Product Warranties

We provide reserves for the estimated costs of product warranties at the time revenue is recognized. We typically offer a twelve month warranty for most of our products. However, in some instances depending upon the product, product components or application of our products by the end customer, our warranties can vary and generally range from six months to five years. We estimate the costs of our warranty obligations on an annualized basis based on our historical experience of known product failure rates, use of materials to repair or replace defective products and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise with specific products. We assess the adequacy of our recorded warranty liabilities and adjust the amounts as necessary.

The following table presents the changes in our warranty reserve during the three and nine months ended April 3, 2021 and March 28, 2020 (in millions):

	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020
Balance as of beginning of period	$	5.7	$	6.8	$	5.0	$	7.5
Provision for warranty	1.7		0.7		5.8		2.5
Utilization of reserve	(1.8)		(2.1)		(5.2)		(4.6)
Balance as of end of period	$	5.6	$	5.4	$	5.6	$	5.4

Environmental Liabilities

Our research and development (“R&D”), manufacturing and distribution operations involve the use of hazardous substances and are regulated under international, federal, state and local laws governing health and safety and the environment. We apply strict standards for protection of the environment and occupational health and safety to sites inside and outside the United States, even if not subject to regulations imposed by foreign governments. We believe that our properties and operations at our facilities comply in all material respects with applicable environmental laws and occupational health and safety laws. However, the risk of environmental liabilities cannot be completely eliminated and there can be no assurance that the application of environmental and health and safety laws will not require us to incur significant expenditures. We are also regulated under a number of international, federal, state and local laws regarding recycling, product packaging and product content requirements. The environmental, product content/disposal and recycling laws are gradually becoming more stringent and may cause us to incur significant expenditures in the future.

Legal Proceedings

We are subject to a variety of claims and suits that arise from time to time in the ordinary course of our business. While management currently believes that resolving claims against us, individually or in the aggregate, will not have a material adverse impact on our financial position, results of operations or statements of cash flows, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. We accrue for loss contingencies when it is both probable that we will incur the loss and when we can reasonably estimate the amount of the loss or range of loss.

Merger Litigation

In connection with our acquisition of Oclaro, seven lawsuits were filed by purported stockholders of Oclaro challenging the proposed merger (the “Merger”). Two of the seven suits were putative class actions filed against Oclaro, its directors, Lumentum, Prota Merger Sub, Inc. and Prota Merger, LLC: Nicholas Neinast v. Oclaro, Inc., et al., No. 3:18-cv-03112-VC, in the United States District Court for the Northern District of California (filed May 24, 2018) (the “Neinast Lawsuit”); and Adam Franchi v. Oclaro, Inc., et al., No. 1:18-cv-00817-GMS, in the United States District Court for the District of Delaware (filed June 9, 2018) (the “Franchi Lawsuit”). Both the Neinstat Lawsuit and the Franchi Lawsuit were voluntarily dismissed with prejudice.

The other five suits, styled as Gerald F. Wordehoff v. Oclaro, Inc., et al., No. 5:18-cv-03148-NC (the “Wordehoff Lawsuit”), Walter Ryan v. Oclaro, Inc., et al., No. 3:18-cv-03174-VC (the “Ryan Lawsuit”), Jayme Walker v. Oclaro, Inc., et al., No. 5:18-cv-03203-EJD (the “Walker Lawsuit”), Kevin Garcia v. Oclaro, Inc., et al., No. 5:18-cv-03262-VKD (the “Garcia Lawsuit”), and SaiSravan B. Karri v. Oclaro, Inc., et al., No. 3:18-cv-03435-JD (the “Karri Lawsuit” and, together with the other six lawsuits, the “Lawsuits”), were filed in the United States District Court for the Northern District of California on May 25, 2018, May 29, 2018, May 30, 2018, May 31, 2018, and June 9, 2018, respectively. These five Lawsuits named Oclaro and its directors as defendants only and did not name Lumentum. The Wordehoff, Ryan, Walker, and Garcia Lawsuits have been voluntarily dismissed, and the Wordehoff, Ryan, and Walker dismissals were with prejudice. The Karri Lawsuit has not yet been dismissed. The Ryan Lawsuit was, and the Karri Lawsuit is, a putative class action.

The Lawsuits generally alleged, among other things, that Oclaro and its directors violated Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder by disseminating an incomplete and misleading Form S-4, including proxy statement/prospectus. The Lawsuits further alleged that Oclaro’s directors violated Section 20(a) of the Exchange Act by failing to exercise proper control over the person(s) who violated Section 14(a) of the Exchange Act.

The remaining Lawsuit (the Karri Lawsuit) currently purports to seek, among other things, damages to be awarded to the plaintiff and any class, if a class is certified, and litigation costs, including attorneys’ fees. A lead plaintiff and counsel has been selected, and an amended complaint was filed on April 15, 2019, which also names Lumentum as a defendant. A motion to dismiss the amended complaint was granted in part and denied in part by the court on October 8, 2020. On December 1, 2020, defendants answered the amended complaint. On December 23, 2020, defendants filed a motion for leave to file a motion for reconsideration of the Court’s October 8 order on the motion to dismiss, which was denied on January 29, 2021. The Karri Lawsuit remains pending with the parties currently in discovery. Defendants intend to defend the Karri Lawsuit vigorously.

Indemnifications

In the normal course of business, we enter into agreements that contain a variety of representations and warranties and provide for general indemnification. Exposure under these agreements is unknown because claims may be made against us in the future and we may record charges in the future as a result of these indemnification obligations. As of April 3, 2021, we did not have any material indemnification claims that were probable or reasonably possible.

Audit Proceedings

We are under audit by various domestic and foreign tax authorities with regards to income tax and indirect tax matters. In some, although not all cases, we have reserved for potential adjustments to our provision for income taxes and accrual of indirect taxes that may result from examinations by these tax authorities or final outcomes in judicial proceedings, and we believe that the final outcome of these examinations, agreements or judicial proceedings will not have a material effect on our results of operations. If events occur which indicate payment of these amounts is unnecessary, the reversal of the liabilities would result in the recognition of benefits in the period we determine the liabilities are no longer necessary. If our estimates of the federal, state, and foreign income tax liabilities and indirect tax liabilities are less than the ultimate assessment, it could result in a further charge to expense.

Note 15. Operating Segments and Geographic Information

Our chief executive officer is our Chief Operating Decision Maker (“CODM”). The CODM allocates resources to the segments based on their business prospects, competitive factors, net revenue and gross margin. We do not track all of our property, plant and equipment by operating segments. The geographic identification of these assets is set forth below.

We are an industry leading provider of optical and photonic products defined by revenue and market share addressing a range of end-market applications including optical communications and commercial lasers. We have two operating segments, Optical Communications, which we refer to as OpComms, and Commercial Lasers, which we refer to as Lasers. Our OpComms products address the following markets: telecommunications and data communications (“Telecom and Datacom”), and consumer and industrial (“Consumer and Industrial”), and include product lines from the acquisition of Oclaro. The two operating segments were primarily determined based on how the CODM views and evaluates our operations. Operating results are regularly reviewed by the CODM to make decisions about resources to be allocated to the segments and to assess their performance. Other factors, including market separation and customer specific applications, go-to-market channels, products and manufacturing, are considered in determining the formation of these operating segments.

OpComms

Our OpComms products include a wide range of components, modules and subsystems to support customers including carrier networks for access (local), metro (intracity), long-haul (city-to-city and worldwide) and submarine (undersea) applications. Additionally, our products address enterprise, cloud, and data center applications, including storage-access networks (“SANs”), local-area networks (“LANs”) and wide-area networks (“WANs”). These products enable the transmission and transport of video, audio and data over high-capacity fiber-optic cables. We maintain leading positions in these fast growing OpComms markets through our extensive product portfolio, including reconfigurable optical add/drop multiplexers (“ROADMs”), coherent dense wavelength division multiplexing (“DWDM”) pluggable transceivers, and tunable small form-factor pluggable transceivers. We also sell laser chips for use in the manufacture of high-speed Datacom transceivers.

In the Consumer and Industrial market, our OpComms diode laser products include vertical cavity surface emitting lasers (“VCSELs”) and edge emitting lasers. In the Consumer end-market, our laser light sources are integrated into 3D sensing cameras which are used in applications in mobile devices, gaming, payment kiosks, computers, and other consumer electronics devices. Applications include biometric identification, computational photography, virtual and augmented reality, and natural user interfaces. Emerging applications for our lasers include automotive safety systems, LiDAR for advanced driver assistance systems in automobiles and autonomous vehicles, self-navigating robotics and drones in industrial applications, and 3D capture of objects coupled with 3D imaging or printing. In the Industrial end-market, our diode lasers are used primarily as pump sources for pulsed and kilowatt class fiber lasers.

Our Lasers products are used in a variety of OEM applications including diode-pumped solid-state, fiber, diode, direct-diode and gas lasers such as argon-ion and helium-neon lasers. Fiber lasers provide kW-class output powers combined with excellent beam quality and are used in sheet metal processing and metal welding applications. Diode-pumped solid-state lasers provide excellent beam quality, low noise and exceptional reliability and are used in biotechnology, graphics and imaging, remote sensing, materials processing and precision machining applications. Diode and direct-diode lasers address a wide variety of applications, including laser pumping, thermal exposure, illumination, ophthalmology, image recording, printing, plastic welding and selective soldering. Gas lasers such as argon-ion and helium-neon lasers provide a stable, low-cost and reliable solution over a wide range of operating conditions, making them well-suited for complex, high-resolution OEM applications such as flow cytometry, DNA sequencing, graphics and imaging and semiconductor inspection.

We also provide high-powered and ultrafast lasers for the industrial and scientific markets. Manufacturers use high-power, ultrafast lasers to create micro parts for consumer electronics and to process semiconductor, LED, and other types of chips. Use of ultrafast lasers for micromachining applications is being driven primarily by the increasing use of consumer electronics and connected devices globally.

We do not allocate research and development, sales and marketing, or general and administrative expenses to our segments because management does not include the information in its measurement of the performance of the operating segments. In addition, we do not allocate amortization and impairment of acquisition-related intangible assets, stock-based compensation and certain other charges impacting the gross margin of each segment because management does not include this information in its measurement of the performance of the operating segments.

Overview

We are an industry-leading provider of optical and photonic products, defined by revenue and market share, addressing a range of end-market applications including Optical Communications, which we refer to as OpComms, and Lasers for manufacturing, inspection and life-science applications. We have two operating segments, OpComms and Lasers. The two operating segments were primarily determined based on how the Chief Operating Decision Maker (“CODM”) views and evaluates our operations. Operating results are regularly reviewed by the CODM to make decisions about resources to be allocated to the segments and to assess their performance. Other factors, including market separation and customer specific applications, go-to-market channels, products and manufacturing, are considered in determining the formation of these operating segments.

We believe the global markets in which Lumentum participates have fundamentally robust, long-term trends that increase the need for our photonics products and technologies. We believe the world is becoming more reliant on ever-increasing amounts of data flowing through optical networks and data centers. Lumentum’s products and technology enable the scaling of these optical networks and data centers to higher capacities. We expect the accelerating shift to digital and virtual approaches to all aspects of work and life that is driving staggering amounts of data in the world’s networks and cloud datacenters will continue into the future. Virtual meetings, video calls, and hybrid in-person and virtual environments for work and other aspects of life will continue to drive strong needs for bandwidth growth and present dynamic new technology challenges that our technology addresses. As manufacturers demand higher levels of precision, new materials, and factory and energy efficiency, suppliers of manufacturing tools globally are turning to laser based approaches, including the types of lasers Lumentum supplies. Laser based 3D sensing and LiDAR is a rapidly developing market. The technology enables computer vision applications that enhance security, safety, and new functionality in the electronic devices that people rely on every day. The use of LiDAR and in-cabin 3D sensing in automobile and delivery vehicles over time significantly adds to our long-term market opportunity. Frictionless and contactless biometric security and access control is of increasing focus globally given the world’s experience with COVID-19. Additionally, we expect 3D enabled machine vision solutions to expand significantly in industrial applications in the coming years.

To maintain and grow our market and technology leadership positions, we are continually investing in new and differentiated products and technologies and customer programs that address both nearer-term and longer-term growth opportunities, as well as continually improving and optimizing our operations. Over many years, we have developed close relationships with market leading customers. We seek to use our core optical and photonic technology and our volume manufacturing capability to expand into attractive emerging markets that benefit from advantages that optical or photonics-based solutions provide.

Termination of Coherent Merger Agreement

On January 18, 2021, we entered into a merger agreement with Coherent, under which we would acquire all outstanding shares of Coherent common stock. In March 2021, Coherent terminated the merger agreement and paid us a termination fee of $217.6 million in accordance with the merger agreement. This gain was offset by $10.1 million of acquisition related expenses and the net amount is presented as “merger termination fee and related costs, net” in our condensed consolidated statements of operations for the three and nine months ended April 3, 2021.

Impact of COVID-19 to our Business

The COVID-19 pandemic has caused public health officials to recommend, and governments to enact, precautions to mitigate the spread of the virus, including travel restrictions and bans, extensive social distancing guidelines, closure or restrictions on business and quarantine or other types of “shelter-in-place” orders in many regions of the world. The pandemic and these related responses have caused, and are expected to continue to cause a global slowdown of economic activity (including a decrease in demand for a broad variety of goods and services), disruptions in global supply chains and significant volatility and potential disruption of financial markets. We have adopted several measures in response to the COVID-19 outbreak including complying with local, state or federal orders that require employees to work from home, instructing employees to work from home in certain jurisdictions, limiting the number of employees onsite which slowed our manufacturing operations in certain countries, enhanced use of personal protective equipment and restricting non-critical business travel by our employees.

34

In the geographies we have operations, we have, in general, been deemed an essential business and been permitted to continue manufacturing and new product development operations in a more limited capacity during the pandemic. This stems from our critical role in global supply chains for the world’s communications and health-care systems. Given the rapidly evolving situation, it is difficult to predict the magnitude and duration of the impact of the COVID-19 pandemic to our markets or precisely when our ability to supply our products will return to full capacity. We are continuing to actively monitor the situation and may take further actions altering our business operations that we determine are in the best interests of our employees, customers, communities, business partners, suppliers, and stockholders, or as required by federal, state, or local authorities. It is not clear what the potential effects any such alterations or modifications may have on our business, including the effects on our customers, employees, and prospects, or on our financial results for fiscal year 2021.

While the recent outbreak of the COVID-19 did not have a material adverse effect on our reported results for our third quarter of fiscal 2021, we are actively monitoring the impact of the coronavirus outbreak. The extent to which our operations will be impacted by the outbreak will depend largely on future developments, which are highly uncertain and cannot be accurately predicted, including new information which may emerge concerning the severity of the outbreak, the speed, efficacy, and acceptance of vaccine distributions, actions by government authorities and private businesses to contain the severity of the outbreak in various geographies and the speed and trajectory of any recovery from the impact of the pandemic, among other things.

COVID-19 has also created dynamics in the semiconductor component supply chains that have led to shortages of the types of components we and our customers require in our products. If we are unable to procure needed semiconductor components, this will impact our ability to supply our products to our customers and may reduce our revenue. If our customers are unable to procure needed semiconductor components, this could reduce their demand for our products and reduce our revenue. The impact of semiconductor component shortages may increase in the near term as supplier and customer buffer inventories and safety stocks are exhausted.

Our primary strategic focus for several years has been technology and product leadership combined with close customer relationships in long-term healthy and growing markets. We believe this strategy is even more apt, and our long-term opportunity is not diminished, with COVID-19. We believe there may be long-term opportunities, as the world’s experience with COVID-19 could drive an increasingly digital and virtual world touching all aspects of life and work that increasingly emphasizes communications systems, cloud services, augmented and virtual reality, and enhanced security. Additionally, ever advancing electronic devices are needed to consume, produce, and communicate digital and virtual content. All these trends could drive the need for higher volumes of higher performing optical devices that we could supply. As such, we expect to continue to invest strongly in new products, technology, and customer programs.

For more information on risks associated with the COVID-19 outbreak and regulatory actions, see the section titled “Risk Factors” in Item 1A of Part II.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as set forth in the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”), and we consider the various staff accounting bulletins and other applicable guidance issued by the United States Securities and Exchange Commission (“SEC”). GAAP, as set forth within the ASC, requires us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions upon which we rely are reasonable based upon information available to us at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the periods presented. To the extent there are differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The accounting policies that reflect our more significant estimates, judgments and assumptions and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results include the following:

•Inventory Valuation

•Revenue Recognition

•Income Taxes

•Goodwill

Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for our fiscal year ended June 27, 2020 provides a more complete discussion of our critical accounting policies and estimates. There have been no significant changes to these policies during the nine months ended April 3, 2021, except for the removal of the long-lived asset valuation policy and the updates resulting from the adoption of Topic 326, as discussed in “Note 2. Recently Issued Accounting Pronouncements”.

Net Revenue

Net revenue increased by $16.7 million, or 4.1%, during the three months ended April 3, 2021 compared to the three months ended March 28, 2020. This increase was primarily due to increased revenue in OpComms of $28.6 million, offset by decreased sales of Lasers of $11.9 million. These results include a deferral of $14.8 million of revenue due to delays in 5G deployments in China.

OpComms net revenue increased by $28.6 million, or 8.0%, during the three months ended April 3, 2021 compared to the three months ended March 28, 2020. Within Opcomms, Telecom and Datacom increased by $4.8 million primarily due to the extra week in the third quarter of fiscal 2021. These results include a deferral of $14.8 million of revenue due to delays in 5G deployments in China. Industrial and Consumer increased by $23.8 million due to the extra week and an expansion of the available market due to an increased dollar content of 3D sensing lasers and higher adoption rates of 3D sensing in consumer electronic devices compared with the prior year. Within Telecom and Datacom, sales of Datacom transceiver products and Lithium Niobate modulators, products, which we are winding down, decreased by $12.8 million.

Lasers net revenue decreased by $11.9 million, or 27.4%, during the three months ended April 3, 2021 compared to the three months ended March 28, 2020, primarily due to COVID-19 reducing customer demand for our kilowatt class fiber lasers.

37

Net revenue increased by $40.2 million, or 3.1%, during the nine months ended April 3, 2021 compared to the nine months ended March 28, 2020. This increase was primarily due to $80.7 million higher OpComms net revenue, offset by $40.5 million lower sales of Lasers.

OpComms net revenue increased by $80.7 million, or 6.8%, during the nine months ended April 3, 2021 compared to the nine months ended March 28, 2020. Within OpComms, sales of Telecom and Datacom increased by $37.9 million and Industrial and Consumer increased by $42.8 million. The Telecom and Datacom increase was primarily due to increased sales of Datacom chips due to market share gains and increased sales of Telecom due to market growth and recovery from the impact of COVID-19 supply constraints, which more than offset the $52.2 million lower sales from product lines we are winding down, such as Datacom transceiver modules and certain Lithium Niobate product lines. These results include a deferral of $14.8 million of revenue due to delays in 5G deployments in China. The Industrial and Consumer increase was primarily driven by an expansion of the available market due to an increased dollar content of 3D sensing lasers and higher adoption rates of 3D sensing in consumer electronic devices compared with the prior comparable period.

Lasers net revenue decreased by $40.5 million, or 32.2%, during the nine months ended April 3, 2021 compared to the nine months ended March 28, 2020, primarily due to COVID-19 reducing customer demand for our kilowatt class fiber lasers.

During the three and nine months ended April 3, 2021, our net revenue from a single customer, which represented 10% or greater of total net revenue was concentrated with two and three customers, who collectively accounted for 44% and 53% of our total net revenue, respectively.

During the three and nine months ended March 28, 2020, our net revenue from a single customer, which represented 10% or greater of total net revenue was concentrated with two customers, who collectively accounted for 37% and 42% of our total net revenue, respectively.

Revenue by Region

We operate in three geographic regions: Americas, Asia-Pacific and EMEA. Net revenue is assigned to the geographic region and country where our product is initially shipped. For example, certain customers may request shipment of our product to a contract manufacturer in one country, however, the location of the end customers may differ. The following table presents net revenue by the three geographic regions we operate in and net revenue from countries within those regions that represented 10% or more of our total net revenue (in millions, except for percentages):

	Three Months Ended								Nine Months Ended
	April 3, 2021				March 28, 2020				April 3, 2021				March 28, 2020

Total net revenue	$	419.5			$	402.8			$	1,350.7			$	1,310.5

For the three and nine months ended April 3, 2021, net revenue from customers outside the United States, based on customer shipping location, represented 90.9% and 92.7% of net revenue, respectively.

For the three and nine months ended March 28, 2020, net revenue from customers outside the United States, based on customer shipping location, represented 90.4% and 90.9% of net revenue, respectively.

38

During the three and nine months ended April 3, 2021 compared to the three and nine months ended March 28, 2020, our net revenue from the Philippines grew due to an introduction of a new product to one of our large customers. 

Our net revenue is primarily denominated in U.S. dollars, including our net revenue from customers outside the United States as presented above. We expect revenue from customers outside of the United States to continue to be an important part of our overall net revenue and an increasing focus for net revenue growth opportunities. However, regulatory and enforcement actions by the United States and other governmental agencies, as well as changes in tax and trade policies and tariffs, have impacted and may continue to impact net revenue from customers outside the United States.

Gross Margin and Segment Gross Margin

The following table summarizes segment gross margin for the three and nine months ended April 3, 2021 and March 28, 2020 (in millions, except for percentages):

	Three Months Ended								Nine Months Ended
	Gross Profit				Gross Margin				Gross Profit				Gross Margin
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020

Total	$	185.0	$	157.7	44.1	%	39.2	%	$	620.3	$	514.5	45.9	%	39.3	%

(1) “Other charges” of unallocated corporate items for the three and nine months ended April 3, 2021 include costs of transferring product lines to new production facilities, including Thailand of $1.4 million and $6.5 million, respectively. We also incurred excess and obsolete inventory charges driven by U.S. trade restrictions and the related decline in demand from Huawei of $1.0 million and $7.7 million during the three and nine months ended April 3, 2021, respectively. Our excess and obsolete inventory charges related to Huawei were offset by $2.1 million of sale of inventory previously written down during the three and nine months ended April 3, 2021. During the nine months ended April 3, 2021, there was also a $5.0 million impairment charge associated with excess capacity related to our Fiber laser business.

“Other charges” of unallocated corporate items for the three and nine months ended March 28, 2020 primarily include costs of transferring product lines to new production facilities, including Thailand of $0.4 million and $8.5 million, respectively. We also incurred excess and obsolete inventory charges driven by the decline in demand from Huawei of $0.1 million and $12.8 million during the three and nine months ended March 28, 2020. In addition, there were expenses of $1.6 million related to the COVID-19 outbreak during the three and nine months ended March 28, 2020.

The unallocated corporate items for the periods presented include the effects of amortization of acquired developed technologies and other intangibles, share-based compensation and certain other charges. We do not allocate these items to the gross margin for each segment because management does not include such information in measuring the performance of the operating segments.

39

Gross Margin

Gross margin for the three months ended April 3, 2021 increased to 44.1% from 39.2% for the three months ended March 28, 2020. The increase was primarily driven by higher OpComms segment gross margins for the three months ended April 3, 2021 compared to the three months ended March 28, 2020, which more than offset lower Lasers segment gross margins.

Gross margin for the nine months ended April 3, 2021 increased to 45.9% from 39.3% for the nine months ended March 28, 2020. The increase in gross margin was due to both higher OpComms and Lasers segment gross margins.

We sell products in certain markets that are consolidating, undergoing product, architectural and business model transitions, have high customer concentrations, are highly competitive, are price sensitive and/or are affected by customer seasonal and mix variant buying patterns. We expect these factors to continue to result in variability of our gross margin.

Although the magnitude of the impact of COVID-19 on our business operations remains uncertain and difficult to predict, and this remains a highly dynamic situation, we have experienced, and we expect that we may continue to experience disruptions to our and our customers’ businesses that will adversely impact our business, financial condition and results of operations.

Segment Gross Margin

OpComms

OpComms gross margin for the three months ended April 3, 2021 increased to 50.1% from 45.0% for the three months ended March 28, 2020. The increase was primarily due to higher manufacturing volumes, a more profitable mix of products, including higher sales of higher margin 3D sensing and lower sales of lower margin Datacom transceiver module and Lithium Niobate modulator products, and the benefits from ongoing operational improvements.

OpComms gross margin for the nine months ended April 3, 2021 increased to 52.2% from 46.4% for the nine months ended March 28, 2020. The increase was primarily due to higher manufacturing volumes, a more profitable mix of products, including higher sales of higher margin 3D sensing and lower sales of lower margin Datacom transceiver module and Lithium Niobate modulator products, and the benefits from ongoing operational improvements.

Lasers

Lasers gross margin for the three months ended April 3, 2021 decreased to 47.2% from 49.7% for the three months ended March 28, 2020. This decrease was primarily due to the lower manufacturing levels related to COVID-19 reducing customer demand for our kilowatt class fiber products.

Lasers gross margin for the nine months ended April 3, 2021 increased to 46.2% from 44.7% for the nine months ended March 28, 2020. This increase was primarily driven by the streamlining of our manufacturing supply chain related to our kilowatt class fiber products over the past year, offset by the impact of lower manufacturing levels related to COVID-19 reducing customer demand for our kilowatt class fiber products.

Research and Development (“R&D”)

R&D expense increased by $8.5 million, or 17.5%, for the three months ended April 3, 2021 compared to the three months ended March 28, 2020. The increase in R&D expense was primarily due to incremental headcount as well as one additional week in the three months ended April 3, 2021, which resulted in an increase in payroll related expense, stock-based compensation, and R&D materials, offset by a reduction in discretionary travel, primarily due to COVID-19 restrictions.

R&D expense increased by $10.8 million, or 7.2%, for the nine months ended April 3, 2021 compared to the nine months ended March 28, 2020. The increase in R&D expense was primarily due to an increase in payroll related expense and stock-based compensation, offset by a decrease in R&D materials, as well as a reduction in discretionary travel, primarily due to COVID-19 restrictions.

We believe that continuing our investments in R&D is critical to attaining our strategic objectives. Despite the uncertainty related to COVID-19 and the global economic outlook, we plan to continue to invest in R&D and new products that we believe will further differentiate us in the marketplace and expect our investment in R&D to increase in absolute dollars in future quarters.

40

Selling, General and Administrative (“SG&A”)

SG&A expense increased by $4.2 million, or 6.9%, during the three months ended April 3, 2021 compared to the three months ended March 28, 2020. The increase in SG&A expense was primarily attributable to an increase in stock-based compensation and payroll related expense due to incremental headcount and one additional week in the three months ended April 3, 2021, as well as an increase in acquisition related costs.

SG&A expense increased by $2.7 million, or 1.5%, during the nine months ended April 3, 2021 compared to the nine months ended March 28, 2020. The increase in SG&A expense was primarily due to an increase in payroll related expense due to incremental headcount, an increase in stock-based compensation, an increase in acquisition related costs, offset by lower discretionary travel and trade shows, primarily due to COVID-19 restrictions.

From time to time, we incur non-core expenses, such as mergers and acquisition-related expenses and litigation expenses, which will likely increase our SG&A expenses and potentially impact our profitability expectations in any particular quarter.

Restructuring and Related Charges

We have initiated various strategic restructuring events primarily intended to reduce costs, consolidate our operations, rationalize the manufacturing of our products and align our business in response to market conditions.

During the three and nine months ended April 3, 2021, we recorded restructuring and related charges of $2.9 million and $3.1 million, respectively, in our condensed consolidated statements of operations. The charges were mainly attributable to severance charges associated with the decision to cease manufacturing of certain products in San Jose, California.

During the three and nine months ended March 28, 2020, we recorded $2.7 million and $4.9 million, respectively, in restructuring and related charges in our condensed consolidated statements of operations. The charges were mainly attributable to severance charges associated with the decision to move certain manufacturing from San Jose, California to our facility in Thailand and other third party vendors.

Merger Termination Fee and Related Costs, Net

On January 18, 2021, we entered into a merger agreement with Coherent, under which we would acquire all outstanding shares of Coherent common stock. In March 2021, Coherent terminated the merger agreement and paid us a termination fee of $217.6 million in accordance with the merger agreement. For each of the three and nine months ended April 3, 2021, we recorded $217.6 million gain related to the receipt of a termination fee from Coherent in March 2021 as a result of the termination of our merger agreement. This gain was offset by $10.1 million of Coherent acquisition related charges and presented as “merger termination fee and related costs, net” in our condensed consolidated statements of operations for the three and nine months ended April 3, 2021.

Impairment Charges

For each of the three and nine months ended March 28, 2020, we recorded impairment charges of $2.5 million of property, plant and equipment related to the decision to exit the Datacom transceiver modules product line. We have had no impairments in fiscal 2021 related to this exit.

41

Interest Expense

For the three months ended April 3, 2021 and March 28, 2020, we recorded interest expense of $16.4 million and $15.6 million, respectively.

For the nine months ended April 3, 2021 and March 28, 2020, we recorded interest expense of $48.7 million and $45.3 million, respectively. The increase in interest expense was mainly driven by the increase in amortization of the debt discount and contractual interest expense of our 2026 Notes (as defined below) issued in fiscal 2020, offset by the decrease in contractual interest expense on our term loan facility (which we repaid in full in the second quarter of fiscal 2020) and a loss on early extinguishment of debt.

Other Income (Expense), Net

The components of other income (expense), net are as follows (in millions):

	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020
Foreign exchange gains (losses), net	$	1.3	$	0.7	$	(3.8)	$	(0.3)
Interest income	1.0		5.2		4.9		12.6
Other income (expense), net	0.1		15.8		1.0		15.6
Total other income (expense), net	$	2.4	$	21.7	$	2.1	$	27.9

For the three and nine months ended April 3, 2021, other income, net decreased by $19.3 million and $25.8 million, respectively, as compared to the three and nine months ended March 28, 2020, mainly driven by a gain on the sale of Lithium Niobate modulators business of $13.8 million recognized in fiscal 2020.

Provision for (Benefit from) Income Taxes

(in millions)	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020
Provision for income taxes	$	27.4	$	5.2	$	58.8	$	19.6

We recorded a tax provision of $27.4 million and $5.2 million for the three months ended April 3, 2021 and March 28, 2020, respectively. Our tax provision for the three months ended April 3, 2021 includes a discrete tax expense of $16.8 million mainly from the tax expense associated with the Coherent termination fee partially offset by currency re-measurement of certain tax related accounts and return-to-provision differences. Our estimated effective tax rate for fiscal 2021 differs from the 21% U.S. statutory rate primarily due to the earnings of our foreign subsidiaries being taxed at rates that differ from the U.S. statutory rate as well as the U.S. federal R&D tax credits, partially offset by the income tax expense from non-deductible stock-based compensation and the tax effect of Global Intangible Low-Taxed Income (“GILTI”), net of benefit for foreign tax credits, and subpart F inclusion.

42

Contractual Obligations

The following table summarizes our contractual obligations as of April 3, 2021, and the effect such obligations are expected to have on our liquidity and cash flow over the next five years (in millions):

	Payments due by period
	Total		Less than 1 year		1 - 3 years		3 - 5 years		More than 5 years
Contractual Obligations
Asset retirement obligations	$	4.7	$	—	$	0.9	$	2.3	$	1.5
Finance lease liabilities, including imputed interest	0.1		0.1		—		—		—
Operating lease liabilities, including imputed interest (1)	70.7		14.0		22.4		13.3		21.0
Pension plan contributions (2)	0.5		0.5		—		—		—
Purchase obligations (3)	224.9		222.0		2.8		0.1		—
Convertible notes - principal (4)	1,500.0		—		450.0		—		1,050.0
Convertible notes - interest (4)	34.9		6.4		12.7		10.5		5.3
Total	$	1,835.8	$	243.0	$	488.8	$	26.2	$	1,077.8

(1) The amounts of operating lease liabilities in the table above do not include any sublease income amounts nor do they include payments for short-term leases or variable lease payments. As of April 3, 2021, we expect to receive sublease income of approximately $3.6 million over the next two years. Refer to “Note 7. Leases” in the notes to condensed consolidated financial statements.

(2) The amount in the preceding table represents planned contributions to our defined benefit plans. Although additional future contributions will be required, the amount and timing of these contributions will be affected by actuarial assumptions, the actual rate of returns on plan assets, the level of market interest rates, legislative changes, and the amount of voluntary contributions to the plan. Any contributions for the following fiscal year and later will depend on the value of the plan assets in the future and thus are uncertain. As such, we have not included any amounts beyond one year in the table above.

(3) Purchase obligations represent legally-binding commitments to purchase inventory and other commitments made in the normal course of business to meet operational requirements. Refer to “Note 14. Commitments and Contingencies” in the notes to condensed consolidated financial statements.

(4) Includes principal and interest on our 0.25% Convertible Notes due in 2024 (the “2024 Notes”) through March 2024, and principal and interest on our 0.50% Convertible Notes due in 2026 (the “2026 Notes” and together with the 2024 Notes, the “Notes”) through December 2026. We have the right to redeem the 2024 Notes and the 2026 Notes in whole or in part at any time on or after March 15, 2024 and on or after December 15, 2026, respectively. The principal balances of our Notes are reflected in the payment periods in the table above based on their respective contractual maturities assuming no conversion. Refer to “Note 9. Debt” in the notes to condensed consolidated financial statements.

As of April 3, 2021, our other non-current liabilities also include $26.6 million of unrecognized tax benefit for uncertain tax positions. We are unable to reliably estimate the timing of future payments related to uncertain tax positions and therefore have excluded them from the preceding table.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as such term is defined in rules promulgated by the SEC, that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

43

Financial Condition

Liquidity and Capital Resources

As of April 3, 2021 and June 27, 2020, our cash and cash equivalents of $687.7 million and $298.0 million, respectively, were largely held in the United States. As of April 3, 2021 and June 27, 2020, our short-term investments of $1,366.9 million and $1,255.8 million, respectively, were all held in the United States. Cash equivalents and short-term investments are primarily comprised of money market funds, treasuries, agencies, high quality investment grade fixed income securities, certificates of deposit, and commercial paper. Our investment policy and strategy is focused on the preservation of capital and supporting our liquidity requirements.

The total amount of cash outside the United States held by the non-US entities as of April 3, 2021 was $100.3 million, which was primarily held by entities incorporated in the United Kingdom, the British Virgin Islands, Japan, Hong Kong, China, Canada, and Thailand. Although the cash currently held in the United States as well as the cash generated in the United States from future operations is expected to cover our normal operating requirements, a substantial amount of additional cash could be required for other purposes, such as capital expenditures to support our business and growth, including costs associated with increasing internal manufacturing capabilities, particularly in our Thailand facility, strategic transactions and partnerships, and future acquisitions.

Our intent is to indefinitely reinvest funds held outside the United States and, except for the funds held in the Cayman Islands, the British Virgin Islands, Japan and Hong Kong, our current plans do not demonstrate a need to repatriate them to fund our domestic operations. However, if in the future, we encounter a significant need for liquidity domestically or at a particular location that we cannot fulfill through borrowings, equity offerings, or other internal or external sources, or the cost to bring back the money is not significant from a tax perspective, we may determine that cash repatriations are necessary or desirable. Repatriation could result in additional material taxes. These factors may cause us to have an overall tax rate higher than other companies or higher than our tax rates have been in the past. Additionally, if conditions warrant, we may seek to obtain additional financing through debt or equity sources. To the extent we issue additional shares, our existing stockholders may be diluted. However, any such financing may not be available on terms favorable to us, or may not be available at all.

As of April 3, 2021, the debt component of our 2024 Notes of $385.3 million (principal balance of $450 million maturing in 2024) is presented in short-term liabilities since our stock price exceeded $78.80 for 20 of the last 30 trading days of the quarter ended April 3, 2021 and the 2024 Notes are convertible at the option of the holders. During the three and nine months ended April 3, 2021, we received conversion requests for less than $0.1 million principal amount of the 2024 Notes, which will be settled in cash in the fourth quarter of fiscal 2021. If the closing price of our stock exceeds $129.08 for 20 of the last 30 trading days of any future quarter, our 2026 Notes would also become convertible at the option of the holders and the debt component would be reclassified to current liabilities in our condensed consolidated balance sheet.

On May 7, 2021, our board of directors approved the 2 year share buyback program, which authorizes us to use up to $700 million to purchase our own shares of common stock. The price, timing, amount, and method of such repurchases will be determined based on the valuation of market conditions and other factors, at prices determined to be attractive and in the best interests of both Lumentum and our stockholders.

Liquidity and Capital Resources Requirements

We believe that our cash and cash equivalents as of April 3, 2021 and cash flows from our operating activities will be sufficient to meet our liquidity and capital spending requirements for at least the next 12 months. However, if market conditions are favorable, we may evaluate alternatives to opportunistically pursue additional financing.

There are a number of factors that could positively or negatively impact our liquidity position, including:

•global economic conditions which affect demand for our products and services and impact the financial stability of our suppliers and customers, including the impact of COVID-19; 

•fluctuations in demand for our products as a result of changes in regulations, tariffs or other trade barriers, and trade relations in general;

•changes in accounts receivable, inventory or other operating assets and liabilities, which affect our working capital;

•increase in capital expenditures to support our business and growth;

•the tendency of customers to delay payments or to negotiate favorable payment terms to manage their own liquidity positions;

44

•timing of payments to our suppliers;

•volatility in fixed income and credit, which impact the liquidity and valuation of our investment portfolios;

•volatility in foreign exchange markets, which impacts our financial results;

•possible investments or acquisitions of complementary businesses, products or technologies, or other strategic transactions or partnerships;

•issuance of debt or equity securities, or other financing transactions, including bank debt;

•potential funding of pension liabilities either voluntarily or as required by law or regulation; and

•the settlement of any conversion or redemption of the 2024 Notes and the 2026 Notes in cash.

As of April 3, 2021, our balance of cash and cash equivalents increased by $389.7 million, to $687.7 million from $298.0 million as of June 27, 2020. The increase in cash and cash equivalents during the nine months ended April 3, 2021 was mainly due to cash provided by operating activities of $614.5 million, including the merger termination fee paid by Coherent of $217.6 million, offset by cash used in investing activities of $196.3 million and cash used in financing activities of $28.5 million.

As of March 28, 2020, our balance of cash, cash equivalents, and restricted cash increased by $256.2 million, to $688.8 million from $432.6 million as of June 29, 2019. The increase in cash, cash equivalents, and restricted cash was mainly due to cash provided by operating activities of $401.6 million and cash provided by financing activities of $332.5 million, offset by cash used in investing activities of $477.9 million during the nine months ended March 28, 2020.

Operating Cash Flow

Cash provided by operating activities was $614.5 million during the nine months ended April 3, 2021. Our net income was $375.8 million for the nine months ended April 3, 2021 and included the merger termination fee paid by Coherent, net of related costs of $207.5 million. Cash provided by operating activities was also generated from $258.8 million of non-cash items (such as depreciation, stock-based compensation, amortization of intangibles, amortization of debt discount and debt issuance costs on our Notes, and other non-cash charges), offset by $20.1 million of changes in our operating assets and liabilities. Changes in our operating assets and liabilities related primarily to an increase in inventories of $20.2 million and a decrease in accounts payable of $41.6 million, offset by an increase in income taxes, net of $28.2 million.

Cash provided by operating activities was $401.6 million during the nine months ended March 28, 2020. Our net income was $140.1 million for the nine months ended March 28, 2020. Cash provided by operating activities was generated primarily from $232.8 million of non-cash items (such as depreciation, stock-based compensation, amortization of intangibles, amortization of debt discount and debt issuance costs on our term loans and convertible notes, and other non-cash charges), and $28.7 million of changes in our operating assets and liabilities. Changes in our operating assets and liabilities related primarily to a decrease in inventories of $48.3 million offset by an increase in accounts receivable of $23.8 million.

Investing Cash Flow

Cash used in investing activities of $196.3 million during the nine months ended April 3, 2021 was primarily attributable to purchases of short-term investments, net of sales and maturities of $121.2 million, capital expenditures of $66.4 million, and payment for asset acquisition of $10.0 million.

Cash used in investing activities of $477.9 million during the nine months ended March 28, 2020 was primarily attributable to purchases of short-term investments, net of sales and maturities of $427.9 million, capital expenditures of $64.9 million, and payment for asset acquisition of $4.0 million, offset by proceeds from sale of product lines of $18.9 million.

Financing Cash Flow

Cash used in financing activities of $28.5 million during the nine months ended April 3, 2021 resulted primarily from tax payments related to restricted stock of $33.8 million, offset by the proceeds from employee stock plans of $5.5 million.

Cash provided by financing activities of $332.5 million during the nine months ended March 28, 2020 resulted primarily from the proceeds of the issuance of the 2026 Notes of $1,042.4 million, net of issuance costs, offset by the repurchase of shares of our common stock of $200.0 million and repayment of our term loan facility of $497.5 million.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

COVID-19 Risk

There are a number of market risk factors related to the COVID-19 pandemic and associated global economic impacts. We continue to actively evaluate these risks, and have taken reserves and financial positions as of April 3, 2021 that we believe are reasonable based on the information currently available. However, the COVID-19 pandemic and related regional shelter-in-place orders are unprecedented events that are continually evolving, and there could be significant changes and/or charges resulting in the future. These market risks include, for example:

•Accounts receivable collectability - there could be significant bad debt expenses incurred if our customers experience financial difficulties.

•Accounts receivable collections timing - our working capital and cash flows could be impacted if we start to agree to longer payment terms for our customers. Although we have not done so, a broader market move to longer payment terms could delay our collection timing as well.

•Inventory (excess and obsolete) - our customers may not be able to purchase inventory that we have built for them, or their demand may slow down to a point where inventory becomes aged.

•Short-term investment values - as seen in past economic slowdowns, there may be credit losses and defaults or a withdrawal of government support programs which cause losses and/or liquidity issues in our investment portfolio.

•Long-term assets such as fixed assets, goodwill, and intangibles - a market slowdown could impair the value of these assets.

•Tax valuation - we have significant NOL’s (Net Operating losses) in the United States which have associated deferred tax assets on our balance sheet, and these could be deemed unrecoverable in the future.

In addition, all of the below market risks are heightened in light of the current market situation. Foreign exchange markets could be impacted and cause significant fluctuations in our future expenses. The price of our common stock has fluctuated significantly in the past and global equity markets are experiencing significant volatility following the COVID-19 outbreak. Interest rates have already reduced dramatically since the onset of the outbreak, and our future income from these investments likely will be negatively impacted in the future.

Foreign Exchange Risk

We conduct our business and sell our products to customers primarily in Asia, Europe, and North America. Due to the impact of changes in foreign currency exchange rates between the U.S. Dollar and foreign currencies, for the three and nine months ended April 3, 2021, we recorded foreign exchange gains (losses), net of $1.3 million and $(3.8) million, respectively, and for the three and nine months ended March 28, 2020, we recorded foreign exchange gains (losses), net of $0.7 million and $(0.3) million, respectively, in the other income (expense), net in the condensed consolidated statements of operations.

Although we sell primarily in the U.S. Dollar, we have foreign currency exchange risks related to our expenses denominated in currencies other than the U.S. Dollar, principally the Chinese Yuan, Canadian Dollar, Thai Baht, Japanese Yen, UK Pound, Swiss Franc and Euro. The volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. In the event our foreign currency denominated assets, liabilities, sales or expenses increase, our operating results may be more greatly affected by fluctuations in the exchange rates of the currencies in which we do business.

Equity Price Risk

We are exposed to equity price risk related to the conversion options embedded in our 2026 Notes and 2024 Notes.

We issued the 2026 Notes in December 2019 and the 2024 Notes in March 2017 with an aggregate principal amount of $1,050 million and $450 million, respectively. Both the 2026 Notes and the 2024 Notes are carried at face value less amortized discount on the condensed consolidated balance sheet. The 2026 Notes and the 2024 Notes bear interest at a rate of 0.50% and 0.25% per year, respectively. Since the Notes bear interest at fixed rates, we have no financial statement risk associated with changes in market interest rates. However, the potential value of the shares to be distributed to the holders of our Notes changes when the market price of our stock fluctuates. The 2026 Notes will mature on December 15, 2026, unless earlier repurchased by us or converted pursuant to their terms, at a conversion price of approximately $99.29 per share. The 2024 Notes will mature on March 15, 2024, unless earlier repurchased by us or converted pursuant to their terms, at a conversion price of approximately $60.62 per share.

46

Since the closing price of our stock exceeded $78.80 for 20 of the last 30 trading days of the third quarter of fiscal 2021, the 2024 Notes have become convertible at the option of the holders. If the closing price of our stock exceeds $129.08 for 20 of the last 30 trading days of any future quarter, our 2026 Notes would also become convertible at the option of the holders.

Interest Rate Fluctuation Risk

As of April 3, 2021, we had cash, cash equivalents, and short-term investments of $2,054.6 million. Cash equivalents and short-term investments are primarily comprised of money market funds, treasuries, agencies, high quality investment grade fixed income securities, certificates of deposit, and commercial paper. Our investment policy and strategy is focused on the preservation of capital and supporting our liquidity requirements. We do not enter into investments for trading or speculative purposes. As of April 3, 2021, the weighted-average life of our investment portfolio was about seven months.

Our fixed-income portfolio is subject to fluctuations in interest rates, which could affect our results of operations. Based on our investment portfolio balance as of April 3, 2021, a hypothetical increase or decrease in interest rates of 1% (100 basis points) would have resulted in a decrease or an increase in the fair value of our portfolio of approximately $8.8 million, and a hypothetical increase or decrease of 0.50% (50 basis points) would have resulted in a decrease or an increase in the fair value of our portfolio of approximately $4.4 million.

Bank Liquidity Risk

As of April 3, 2021, we had approximately $114.8 million of unrestricted cash (excluding cash equivalents) in operating accounts that are held with domestic and international financial institutions. These cash balances could be lost or become inaccessible if the underlying financial institutions fail or if they are unable to meet the liquidity requirements of their depositors and if they are not supported by the national government of the country in which such financial institution is located. Notwithstanding, we have not incurred any losses to date and have had full access to our operating accounts. We believe any failures of domestic and international financial institutions could impact our ability to fund our operations in the short term.

Item 4. Controls and Procedures 

(a) Evaluation of Disclosure Controls and Procedures

Our management (with the participation of our Principal Executive Officer and Principal Financial Officer), as of the end of the period covered by this Quarterly Report, evaluated the effectiveness of our disclosure controls and procedures. Based on this evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) were effective to provide reasonable assurance that the information required to be disclosed by us in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting as defined in Exchange Act Rules 13a-15(f) and 15d-15(f), identified in connection with the evaluation required by Exchange Act Rules 13a-15(d) or 15d-15(d) that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(c) Inherent Limitations on Effectiveness of Controls

Our management, including the CEO and CFO, recognizes that our disclosure controls and procedures or our internal control over financial reporting cannot prevent or detect all possible instances of errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.

48

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

We are subject to a variety of claims and suits that arise from time to time in the ordinary course of our business. While management currently believes that resolving claims against us, individually or in the aggregate, will not have a material adverse impact on our financial position, results of operations or cash flows, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. Should we experience an unfavorable final outcome, there exists the possibility of a material adverse impact on our financial position, results of operations or cash flows for the period in which the effect becomes reasonably estimable.

Merger Litigation

In connection with our acquisition of Oclaro, seven lawsuits were filed by purported stockholders of Oclaro challenging the proposed merger (the “Merger”). Two of the seven suits were putative class actions filed against Oclaro, its directors, Lumentum, Prota Merger Sub, Inc. and Prota Merger, LLC: Nicholas Neinast v. Oclaro, Inc., et al., No. 3:18-cv-03112-VC, in the United States District Court for the Northern District of California (filed May 24, 2018) (the “Neinast Lawsuit”); and Adam Franchi v. Oclaro, Inc., et al., No. 1:18-cv-00817-GMS, in the United States District Court for the District of Delaware (filed June 9, 2018) (the “Franchi Lawsuit”). Both the Neinast Lawsuit and the Franchi Lawsuit were voluntarily dismissed with prejudice.

The other five suits, styled as Gerald F. Wordehoff v. Oclaro, Inc., et al., No. 5:18-cv-03148-NC (the “Wordehoff Lawsuit”), Walter Ryan v. Oclaro, Inc., et al., No. 3:18-cv-03174-VC (the “Ryan Lawsuit”), Jayme Walker v. Oclaro, Inc., et al., No. 5:18-cv-03203-EJD (the “Walker Lawsuit”), Kevin Garcia v. Oclaro, Inc., et al., No. 5:18-cv-03262-VKD (the “Garcia Lawsuit”), and SaiSravan B. Karri v. Oclaro, Inc., et al., No. 3:18-cv-03435-JD (the “Karri Lawsuit” and, together with the other six lawsuits, the “Lawsuits”), were filed in the United States District Court for the Northern District of California on May 25, 2018, May 29, 2018, May 30, 2018, May 31, 2018, and June 9, 2018, respectively. These five Lawsuits named Oclaro and its directors as defendants only and did not name Lumentum. The Wordehoff, Ryan, Walker, and Garcia Lawsuits have been voluntarily dismissed, and the Wordehoff, Ryan, and Walker dismissals were with prejudice. The Karri Lawsuit has not yet been dismissed. The Ryan Lawsuit was, and the Karri Lawsuit is, a putative class action.

The Lawsuits generally alleged, among other things, that Oclaro and its directors violated Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder by disseminating an incomplete and misleading Form S-4, including proxy statement/prospectus. The Lawsuits further alleged that Oclaro’s directors violated Section 20(a) of the Exchange Act by failing to exercise proper control over the person(s) who violated Section 14(a) of the Exchange Act.

The remaining Lawsuit (the Karri Lawsuit) currently purports to seek, among other things, damages to be awarded to the plaintiff and any class, if a class is certified, and litigation costs, including attorneys’ fees. A lead plaintiff and counsel has been selected, and an amended complaint was filed on April 15, 2019, which also names Lumentum as a defendant. A motion to dismiss the amended complaint was granted in part and denied in part on October 8, 2020. On December 1, 2020, defendants answered the amended complaint. On December 23, 2020, defendants filed a motion for leave to file a motion for reconsideration of the Court’s October 8 order on the motion to dismiss, which was denied on January 29, 2021. The Karri Lawsuit remains pending with the parties currently in discovery. Defendants intend to defend the Karri Lawsuit vigorously.

Risks Related to Our Business

Our business operations, financial performance, results of operations, financial position and the achievement of our strategic objectives may be materially and adversely affected by the ongoing COVID-19 pandemic.

Our business, results of operations and financial performance have been negatively impacted by the COVID-19 pandemic and related public health responses, such as shelter-in-place orders, social distancing protocols, and travel restrictions in many of the countries and regions in which we have operations or manufacturing partners.

As a result of the COVID-19 outbreak around the world, beginning in early February 2020, Lumentum implemented certain travel restrictions, temporarily closed or limited the number of employees permitted onsite in our offices and manufacturing sites in several heavily impacted locations, and implemented work-from-home rules at most of our facilities. We continue to monitor changes in each location and adjust the restrictions as circumstances require. These measures as well as additional workforce disruptions due to quarantines, governmental actions, and/or the social distancing measures we have taken to mitigate the impact of COVID-19 at certain of our locations around the world in an effort to protect the health and well-being of our employees, customers, suppliers and the communities in which we operate, have caused, and may continue to cause, disruption and delays in our ability to operate and manufacture, test and assemble products in our internal facilities, particularly in the United States, China, Thailand and the United Kingdom. Our ability to continue certain research and development activities has also been limited which could materially and adversely affect our ability to develop new products and technologies on the timelines we previously anticipated.

51

In addition, we have experienced disruption and delays in our supply chain and with our manufacturing partners, for example in Malaysia, which imposed limitations at certain times on which businesses could operate and the amount of the workforce permitted to perform manufacturing operations, and those limitations could be reinstated if the number of COVID-19 cases in particular regions were to increase. As a result, there is considerable uncertainty regarding the duration of such limitations and potential future restrictions, and complexity in ensuring compliance. Our supply chain has also been affected by measures implemented in response to the pandemic and our suppliers may not have the materials, capacity or capability to supply us with the components necessary for continuing our manufacturing operations or development efforts at our normal levels. There are also restrictions and delays on logistics, such as air cargo carriers, as well as increased logistics costs due to limited capacity and high demands for freight forwarders. Similarly, our customers have also experienced, and could continue to experience, disruptions in their operations, which may result in reduced, delayed, or canceled orders, and has increased collection risks, which may adversely affect our results of operations. These disruptions, delays and restrictions have adversely affected our revenue and results of operations and could be extended or further restrictions could be put in place in other regions, which would materially and adversely impact our revenue, results of operations and financial condition.

The COVID-19 pandemic has created economic uncertainty and volatility in the financial markets around the world, resulting in an economic downturn that has affected and may continue to affect demand for our products and impact our results of operations. The ultimate impact of the COVID-19 pandemic on our operations and financial performance depends on many factors that are not within our control, including, but not limited, to: governmental, business and individuals’ actions that have been and continue to be taken in response to the pandemic (including restrictions on travel and transport and workforce pressures); the impact of the pandemic and actions taken in response on global and regional economies, travel, and economic activity; the availability of federal, state, local or non-U.S. funding programs; general economic uncertainty in key global markets and financial market volatility; global economic conditions and levels of economic growth; and the pace of recovery when the COVID-19 pandemic subsides (including the availability of treatments and vaccines). In addition, the global economic volatility has significantly impacted the foreign exchange markets, and the currencies of various countries in which we operate and in which we have significant volume of local-currency denominated expenses have seen significant volatility. The magnitude of the impact of COVID-19 on our business operations remains uncertain and difficult to predict, and the situation remains highly dynamic. We have experienced and will continue to experience in subsequent periods, disruptions to our business that will adversely impact our business, financial condition and results of operations.

Changing technology and intense competition require us to continuously innovate while controlling product costs, and our failure to do so may result in decreased revenues and profitability.

The markets in which we operate are dynamic and complex, and our success depends upon our ability to deliver both our current product offerings and new products and technologies on time and at acceptable prices to our customers. The markets for our products are characterized by rapid technological change, frequent new product introductions and enhancements, substantial capital investment, changes in customer requirements, continued price pressures and a constantly evolving industry. Historically, these pricing pressures have led to a continued decline of average selling prices across our business. The development of new, technologically advanced products is a complex and uncertain process requiring high levels of innovation and the accurate prediction of technology and market trends, and is further impacted by the disruptions caused by COVID-19 on our ability to continue with research and development activities. The introduction of new products also often requires significant investment to ramp up production capacity, the benefit of which may not be realized if we are not successful in the production of such products or if customer demand does not develop as expected. Ramping of production capacity also entails risks of delays which can limit our ability to realize the full benefit of new product introductions. We cannot assure you that we will be able to identify, develop, manufacture, market or support new or enhanced products successfully, if at all, or on a timely basis. We also cannot assure you that potential markets for our new products will materialize on the timelines we anticipate, or at all, or that our technology will meet our customers’ specifications. Our future performance will depend on the successful development, introduction, deployment and market acceptance of new and enhanced features and products that meet our customers’ current and future needs.

The market for optical communications products in particular has matured over time and these products have increasingly become subject to commoditization. Both legacy competitors as well as new entrants, predominantly Asia-based competitors, have intensified market competition in recent years leading to pricing pressure. To preserve our revenues and product margin structures, we remain reliant on an integrated customer and market approach that anticipates end customer needs as Telecom and Datacom requirements evolve. We also must continue to develop more advanced, differentiated products that command a premium with customers, while conversely continuing to focus on streamlining product costs for established legacy products. If we fail to continue to develop enhanced or new products, or over time are unable to adjust our cost structure to continue to competitively price more mature products, our financial condition and results of operations could be materially and adversely affected.

52

We rely on a limited number of customers for a significant portion of our sales; and the majority of our customers do not have contractual purchase commitments.

We have consistently relied on a small number of customers for a significant portion of our sales and in certain of our markets, such as 3D sensing and commercial lasers, this customer concentration is particularly acute. We expect that this customer concentration will continue in the future, and we expect that our growth prospects will continue to depend in part on a small number of customers. Many of our customers purchase products under purchase orders or under contracts that do not contain volume or long-term purchase commitments. Some customers provide us with their expected forecasts for our products several months in advance, but these customers may decrease, cancel or delay purchase orders already in place, including on short notice, particularly in light of the impacts of COVID-19 on their businesses and markets, and the impact of any such actions may be intensified given our dependence on a limited number of large customers. In addition, changes in the business requirements, vendor selection, project prioritization, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased or timing of purchases) of our key customers, or any real or perceived quality issues related to the products that we sell to such customers, could significantly decrease our sales to such customers or could lead to delays or cancellations of planned purchases of our products or services, which increases the risk of quarterly fluctuations in our revenues and operating results. Our relationships with large customers may also be harmed to the extent the impacts of the COVID-19 pandemic prevent us from being able to satisfy their orders in a timely manner. There are also continuing trade tensions, including an uncertain regulatory environment, in the U.S. and countries in Asia, which could materially impact our sales to key customers in these regions. Further, we may be required to purchase raw materials, increase production capacity or make other changes to our business to accommodate certain large customers. If forecasted orders do not materialize, we may need to reduce investment in R&D activities, we may fail to optimize our manufacturing capacity, we may incur liabilities with our suppliers for reimbursement of capital expenditures, or we may have excess inventory. In addition, if we incur expenses in response to forecasted demand and do not have a corresponding increase in revenue, our profitability may suffer. Any of these factors could adversely affect our business, financial condition and results of operations.

Our ability to sell our products to a significant customer has been restricted.

On May 16, 2019, Huawei Technologies Co. Ltd. and 68 designated non-U.S. affiliates (collectively, “Huawei”) were added to the Entity List of the Bureau of Industry and Security of the U.S. Department of Commerce (“BIS”), which imposes limitations on the supply of certain U.S. items and product support to Huawei. We suspended shipments of all products to Huawei until we were able to review our product portfolio and determine whether our products are subject to the Export Administration Regulations (“EAR”), and therefore within the scope of the Entity List restrictions. We resumed shipments of certain of our products to Huawei during the quarter ended June 29, 2019 after determining that such products are not subject to the EAR in effect at that time.

On August 17, 2020, BIS issued final rules that further restrict access by Huawei to items produced domestically and abroad from U.S. technology and software. The final rules will prevent us from selling certain products to Huawei entities without a license issued subject to the EAR. Further, even if there are products unaffected by the rule or for which we are able to obtain an export license, Huawei may not be able to source products from other suppliers due to the final rules, which could impact Huawei’s demand for our products.

Under the current regulatory regime, our business with Huawei has been and will continue to be more limited than it was in the past. For example, we have been unable to supply certain additional products and may be limited or unable to work with Huawei on future product developments while Huawei remains on the Entity List, which may negatively impact our financial condition and results of operations. Huawei may seek to obtain similar or substitute products from our competitors that are not subject to these restrictions, or to develop similar or substitute products themselves. At this time, we believe that sales to Huawei will decline in fiscal year 2021 when compared to fiscal year 2020.

We cannot be certain what additional actions the U.S. government may take with respect to Huawei or other entities in China or other countries, including additional changes to the Entity List restrictions, export regulations, tariffs or other trade restrictions. We are unable to predict the duration of the restrictions enacted in May 2019 through August 2020, including the recent restrictions on Huawei’s access to foreign-made chips made using U.S. technology which could have a long-term adverse effect on our business. The U.S. government has added other customers of ours to the Entity List, such as FiberHome Technologies Group in May 2020, and may continue to do so or otherwise restrict our ability to ship products which may harm our business, financial condition and results of operations.

53

We also manufacture customized products for Huawei, and therefore may be unable to sell certain finished goods inventory to alternative customers, or may be unable to utilize such manufacturing capabilities for products for alternative customers, which may result in further excess and obsolete inventory charges and/or underutilized capacity charges in future periods. In addition, we sell various non-customized products to Huawei in which Huawei represents a significant portion of the related products’ demand.  We have taken charges, and may have significant future charges, for common components which become excess as a result of the inability to sell to Huawei. Future charges related to trade restrictions could be caused by either additional regulatory restrictions enacted with respect to Huawei, or revisions to our estimates of the impact from already-enacted restrictions.  Additional charges may also occur with respect to customized products that we manufacture for other customers in the event that such customers were to be added to the Entity List or otherwise if our ability to sell to such customers were restricted. This trade uncertainty may cause delays or cancellations, which could adversely affect our business, financial conditions and operating results. We believe this trade uncertainty has caused and may in the future cause delays or cancellations, which could adversely affect our business, financial conditions and operating results.

Intense competition in our markets may lead to an accelerated reduction in our prices, revenues, margins and market share.

The end markets for optical products have experienced significant industry consolidation during the past few years. As a result, the markets for optical subsystems, components and laser diodes are highly competitive. Our current competitors include a number of domestic and international public and private companies, many of which may have substantially greater financial, technical, marketing and distribution resources and brand name recognition than we have. Our competitors include II-VI, Acacia Communications (which was acquired by Cisco in March 2021), AMS, Broadcom, Coherent (which has entered into a merger agreement with II-VI), Fujitsu Optical Components, Furukawa Electric, IPG Photonics, MACOM, Mitsubishi Electric, Molex, Neophotonics, nLight, O-net Communications, Sumitomo Electric Industries and Trumpf. We may not be able to compete successfully against either current or future competitors. Our competitors may continue to enter markets or gain or retain market share through introduction of new or improved products or with aggressive low pricing strategies that may impact the efficacy of our approach. Additionally, the merger or consolidation of significant competitors, for example, II-VI’s acquisition of Finisar in September of 2019 and its pending acquisition of Coherent, the acquisition of Acacia Communications by Cisco in March 2021, and the acquisition of OSRAM by AMS in December 2019, may result in competitors with greater resources, enable them to offer a different market approach, or a lower cost structure through economies of scale or other efficiencies that we may be unable to match and which may intensify competition in the various markets. Further, our competitors may seek to vertically integrate by buying suppliers that also supply products or components to us, which could enable them to further reduce prices, or could increase our costs. Increased competition could result in significant price erosion, reduced revenue, lower margins or loss of market share, any of which would significantly harm our business.

We are subject to risks arising from our international operations, which may adversely affect our business, financial condition, and results of operations.

We derive a majority of our revenue from our international operations, and we plan to continue expanding our business in international markets in the future. In addition, we have extensive international manufacturing capabilities through third-party contract manufacturers, as well as through our own international facilities, with employees engaged in R&D, administration, manufacturing, support and sales and marketing activities.

As a result of our international operations, in addition to similar risks we face in our U.S. operations, we are affected by economic, business, regulatory, social, and political conditions in foreign countries, including the following:

•    impacts related to business disruptions and restrictions related to COVID-19;

•    changes in general IT spending;

•    less effective protection of intellectual property;

•    the imposition of government controls, inclusive of critical infrastructure protection;

•    changes in or limitations imposed by trade protection laws or other regulatory orders or requirements in the United States or in other countries, including tariffs, sanctions, or other costs or requirements which may affect our ability to import or export our products from various countries or increase the cost to do so, including government action to restrict our ability to sell to foreign customers where sales of products may require export licenses (such as the U.S. Department of Commerce’s addition of Huawei to the Entity List in May 2019, the addition of FiberHome in May 2020, amendment to the Foreign-Produced Direct Product Rule in August 2020 and the prohibition of export and sale of certain products to ZTE Corporation in early 2018) and increased tariffs on various products that have been proposed by the U.S. government and other non-U.S. governments;

54

•    the imposition of sanctions on customers in China may cause those customers to seek domestic alternatives to our products, including developing alternatives internally, and our customers demand for our products could be impacted by their inability to obtain other materials subject to sanctions. For example, sanctions on certain US semiconductors and semiconductor equipment has caused a delay in 5G deployment in China while the affected companies seek alternative solutions, which has reduced the demand for our products from some of our Chinese customers;

•    varying and potentially conflicting laws and regulations;

•    potential global or regional recession as a result of the COVID-19 pandemic and related responses of individuals, governments, private industry;

•    wage inflation or a tightening of the labor market;

•    political developments of foreign nations, including Brexit and recent political developments in Hong Kong and the potential impact such developments or further actions could have on our customers in Hong Kong; and

•    the impact of the following on service provider and government spending patterns as well as our contract and internal manufacturing: political considerations, unfavorable changes in tax treaties or laws, unfavorable events that affect foreign currencies on an absolute or relative basis, natural disasters, epidemic disease, labor unrest, earnings expatriation restrictions, misappropriation of intellectual property, military actions, acts of terrorism, political and social unrest and difficulties in staffing and managing international operations.

Additionally, our business is impacted by fluctuations in local economies and currencies. The COVID-19 pandemic and resulting global economic volatility has significantly impacted the foreign exchange markets, and the currencies of various countries in which we operate and have significant volume of local-currency denominated expenses have seen significant volatility. We expect such volatility to continue, which could negatively impact our results by making our non-U.S. operations more expensive when reported in US dollars, primarily due to the costs of payroll.

Moreover, local laws and customs in many countries differ significantly from or conflict with those in the United States or other countries in which we operate. In many foreign countries, particularly in those with developing economies, it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. regulations applicable to us. There can be no assurance that our employees, contractors, channel partners and agents will not take actions in violation of our policies and procedures, which are designed to ensure compliance with U.S. and foreign laws and policies. Violations of laws or key control policies by our employees, contractors, channel partners, or agents could result in termination of our relationships with customers and suppliers, financial reporting problems, fines and/or penalties for us, or prohibition on the importation or exportation of our products, and could have a material adverse effect on our business, financial condition and results of operations.

In addition to the above risks related to our international operations, we also face risks related to health epidemics, such as the COVID-19 pandemic. An outbreak of a contagious disease, and other adverse public health developments, particularly in Asia, could have a material and adverse effect on our business operations. The effects could include restrictions on our ability to travel to support our sites in Asia or our customers located there, disruptions in our ability to distribute products, and/or temporary closures of our facilities in Asia or the facilities of our suppliers or customers and their contract manufacturers. Disruption to the operations of our suppliers or customers and their contract manufacturers due to COVID-19 have impacted and will likely continue to impact our sales and operating results. For additional information regarding the impact of COVID-19 on our business, see the risk factor above titled “Our business operations, financial performance, results of operations, financial position and the achievement of our strategic objectives may be materially and adversely affected by the ongoing COVID-19 pandemic.”

Any or all of these factors could have a material adverse impact on our business, financial condition, and results of operations.

The manufacturing of our products may be adversely affected if we are unable to manufacture certain products in our manufacturing facilities or if our contract manufacturers and suppliers fail to meet our production requirements.

55

We manufacture some of our finished good products as well as some of the components that we provide to our contract manufacturers in our China, Japan, Thailand, U.K., and San Jose, California manufacturing facilities. For some of the components and finished good products, we are the sole manufacturer. Our manufacturing processes are highly complex, and issues are often difficult to detect and correct. From time to time we have experienced problems achieving acceptable yields in our manufacturing facilities, resulting in delays in the availability of our products and inability to meet customer demand. In addition, if we experience problems with our manufacturing facilities or are unable to continue operations at any of these sites, including as a result of social, geopolitical, environmental or health factors, including pandemics or widespread health epidemics such as COVID-19 impacts, it would be costly and require a long period of time to move the manufacture of these components and finished good products to a different facility or contract manufacturer which could then result in interruptions in supply, and would likely materially impact our financial condition and results of operations. Our manufacturing is heavily concentrated in central Asia, and we would be severely impacted if there were further escalation of COVID-19 or related restrictions imposed by governments or private industry in that region.

We also rely on several independent contract manufacturers to supply us with certain products. For many products, a particular contract manufacturer may be the sole source of the finished good products. We depend on these manufacturers to meet our production and capacity requirements and to provide quality products to our customers. If operations at these contract manufacturers is adversely impacted, such as by restrictions due to COVID-19 or any resulting economic impact to their business, this would likely materially impact our financial condition and results of operations. Our ability to control the quality of products produced by contract manufacturers has and may in the future be impaired due to COVID-19 disruptions, and quality issues might not be resolved in a timely manner. Additionally, if our contract manufacturers continue experiencing disruptions or discontinue operations, we may be required to identify and qualify alternative manufactures, which is expensive and time consuming. If we are required to change or qualify a new contract manufacturer, this would likely cause business disruptions and could harm our existing customer relationships.

In addition, despite rigorous testing for quality, both by us and the contract manufacturers to whom we sell products, we may receive and ship defective products. We may incur significant costs to correct defective products which could result in the loss of future sales and revenue, indemnification costs or costs to replace or repair the defective products, litigation and damage to our reputation and customer relations. Defective products may also cause diversion of management attention from our business and product development efforts.

Additionally, our ability to fulfill our customers’ demand, or the ability of our contract manufacturers to fulfill their obligations, may be affected by natural disasters, including a global pandemic such as COVID-19, changes in legal requirements, labor strikes and other labor unrest and economic, political or other forces that are beyond our control. For example, in the past we experienced a labor strike at one of our contract manufacturers which threatened the contract manufacturer’s ability to fulfill its product commitments to us and, in turn, our ability to fulfill our obligations to our customers. There is also an increased focus on corporate social and environmental responsibility in our industry. As a result, a number of our customers may adopt policies that include social and environmental responsibility provisions that their suppliers should comply with. These provisions may be difficult and expensive to comply with, given the complexity of our supply chain. We may be unable to cause our suppliers or contract manufactures to comply with these provisions which may adversely affect our relationships with customers. Further, certain of our contract manufacturers are located in China, which exposes us to risks associated with Chinese laws and regulations and U.S. laws, regulations and policies with respect to China, such as those related to import and export policies, tariffs, taxation and intellectual property. Chinese laws and regulations are subject to frequent change, and if our contract manufacturers are unable to obtain or retain the requisite legal permits or otherwise to comply with Chinese legal requirements, we may be forced to obtain products from other manufacturers or to make other operational changes, including transferring our manufacturing to another manufacturer or to our own manufacturing facilities. Any such developments could have a material impact on our ability to meet our customers’ expectations and may materially impact our operating results and financial condition. The United States has imposed tariffs on the import of certain products manufactured in China, and may propose further tariffs in the future, which could increase costs associated with the manufacturing of our products in China, and potentially other countries, and negatively impact our sales levels and profit margins.

In addition, for a variety of reasons, including changes in circumstances at our contract manufacturers, restrictions or inability to operate due to COVID-19, or regarding our own business strategies, we may choose or be required to transfer the manufacturing of certain products to other manufacturing sites, including to our own manufacturing facilities. As a result of such transfers, our contract manufacturers may prioritize other customers or otherwise be unable or unwilling to meet our demand. There also may be delays with the transfer of manufacturing equipment and successfully setting up that equipment at the transfer sites and training new operators. If such transfers are unsuccessful or take a longer period of time than expected, it could result in interruptions in supply and supply chain, and would likely impact our financial condition and results of operations.

56

Some of our purchase commitments with contract manufacturers are not cancellable which may impact our results of operations if customer forecasts driving these purchase commitments do not materialize and we are unable to sell the products to other customers. Alternatively, our contract manufacturers may not be able to meet our demand which would inhibit our ability to meet our customers’ demands and maintain or grow our revenues. Furthermore, it could be costly and require a long period of time to move products from one contract manufacturer to another which could result in interruptions in supply and adversely impact our financial condition and results of operations.

In addition, many of our products are sourced from suppliers based outside of the United States, primarily in Asia. Uncertainty with respect to our suppliers’ abilities due to COVID-19 impacts, tax and trade policies, tariffs and government regulations affecting trade between the United States and other countries has recently increased. Major developments in tax policy or trade relations, such as the imposition of tariffs on imported products, could increase our product and product-related costs or require us to seek alternative suppliers, either of which could result in decreased sales or increased product and product-related costs.

If our customers do not qualify our manufacturing lines or the manufacturing lines of our subcontractors for volume shipments, our operating results could suffer.

Certain of our customers do not purchase products, other than limited numbers of evaluation units, prior to qualification of the manufacturing line for volume production. Our existing manufacturing lines, as well as each new manufacturing line, must pass through varying levels of qualification with certain of our customers. Some of our customers require that our manufacturing lines pass their specific qualification standards and that we, and any subcontractors that we may use, be registered under international quality standards. We may encounter quality control issues as a result of setting up new manufacturing lines in our facilities, relocating our manufacturing lines or introducing new products to fill production. We may be unable to obtain, or we may experience delays in obtaining, customer qualification of our manufacturing lines. If we introduce new contract manufacturing partners and move any production lines from existing internal or external facilities, the new production lines will likely need to be re-qualified with our customers. Any delays or failure to obtain qualifications would harm our reputation, operating results, and customer relationships.

We depend on a limited number of suppliers for raw materials, packages and components, and any failure or delay by these suppliers in meeting our requirements could have an adverse effect on our business and results of operations.

We purchase raw materials, packages and components from a limited number of suppliers, who are often small and specialized. Additionally, some of our suppliers are our sole sources for certain materials, equipment and components. We depend on the timely and continued supply and quality of the materials, packages and components that our suppliers supply to us. We have not entered into long-term agreements with many of these suppliers. We do not have a guarantee of supply from these suppliers and as a result, there is no assurance that we would be able to secure the equipment or components that we require, in sufficient quantity, quality and on reasonable terms. Our business and results of operations have been, and could continue to be, adversely affected by this dependency. Specific concerns we periodically encounter with our sole suppliers or limited number of suppliers include receipt of defective parts or contaminated materials, stoppages or delays of supply, insufficient resources to supply our requirements, substitution of more expensive or less reliable materials, increases in the price of supplies, and an inability to obtain reduced pricing from our suppliers in response to competitive pressures. Additionally, these suppliers may be unable to operate under restrictions due to COVID-19 or any resulting economic impact to their business and ability to continue operations, and the supply of and costs of raw materials may be negatively impacted by the COVID-19 pandemic, trade protection policies such as tariffs, or escalating trade tensions, particularly with countries in Asia. Specifically, these smaller suppliers may be particularly susceptible to prevailing economic conditions. Any disruption in the supply of the raw materials, packaging or components used in the manufacture and delivery of our products could have a material adverse impact on our business, financial condition and results of operations.

We contract with a number of large OEM and end-user service providers and product companies that have considerable bargaining power, which may require us to agree to terms and conditions that could have an adverse effect on our business or ability to recognize revenues.

57

Large OEM and end-user service providers and product companies comprise a significant portion of our customer base. These customers generally have greater purchasing power than smaller entities and, accordingly, often request and receive more favorable terms from suppliers, including us. As we seek to expand our sales to existing customers and acquire new customers, we may be required to agree to terms and conditions that are favorable to our customers and that may affect the timing of our ability to recognize revenue, increase our costs and have an adverse effect on our business, financial condition, and results of operations. Furthermore, large customers have increased buying power and ability to require onerous terms in our contracts with them, including pricing, warranties, and indemnification terms. If we are unable to satisfy the terms of these contracts, it could result in liabilities of a material nature, including litigation, damages, additional costs, loss of market share and loss of reputation. Additionally, the terms these large customers require, such as most-favored nation or exclusivity provisions, may impact our ability to do business with other customers and generate revenues from such customers.

Our products may contain defects that could cause us to incur significant costs, divert our attention from product development efforts and result in loss of customers.

Our products are complex and defects may be found from time to time. Networking products in particular frequently contain undetected software or hardware defects when first introduced or as new versions are released. In addition, our products are often embedded in or deployed in conjunction with our customers’ products which incorporate a variety of components produced by third parties, which may contain defects. As a result, when problems occur, it may be difficult to identify the source of the problem. These problems may cause us to incur significant damages or warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and manufacturing resources, and cause significant customer relation problems or loss of customers, or risk exposure to product liability suits, all of which would harm our business.

Our sales may decline if we are unable to obtain government authorization to export certain of our products, and we may be subject to legal and regulatory consequences if we do not comply with applicable export control laws and regulations.

Exports of certain of our products are subject to export controls imposed by the U.S. government and administered by the U.S. Departments of State and Commerce. In certain instances, these regulations may require pre-shipment authorization from the administering department. For products subject to the Export Administration Regulations (“EAR”) administered by the Department of Commerce’s Bureau of Industry and Security, the requirement for a license is dependent on the type and end use of the product, the final destination, the identity of the end user and whether a license exception might apply. Virtually all exports of products subject to the International Traffic in Arms Regulations (“ITAR”) administered by the Department of State’s Directorate of Defense Trade Controls, require a license. Certain of our fiber optics products are subject to EAR and certain of our RF-over-fiber products, as well as certain products and technical data, are developed with government funding, and are currently subject to ITAR. Products and the associated technical data developed and manufactured in our foreign locations are subject to export controls of the applicable foreign nation.

Given the current global political climate, obtaining export licenses can be difficult and time-consuming. Failure to obtain export licenses for these shipments could significantly reduce our revenue and materially adversely affect our business, financial condition, relationships with our customers and results of operations. Compliance with U.S. government regulations also subjects us to additional fees and costs. The absence of comparable restrictions on competitors in other countries may adversely affect our competitive position.

Further, there is increased attention from the government and the media regarding potential threats to U.S. national security and foreign policy relating to certain foreign entities, particularly Chinese entities, and the imposition of enhanced restrictions or sanctions regarding the export of our products or on specific foreign entities that would restrict their ability to do business with U.S. companies may materially adversely affect our business. For example, on May 16, 2019, Huawei was added to the Entity List of the Bureau of Industry and Security of the U.S. Department of Commerce, additional regulatory restrictions were imposed in May and August 2020 to the Foreign-Produced Direct Product Rule, which impose limitations on the supply of certain U.S. items and product support to Huawei, and FiberHome Technologies was added to the Entity List on May 22, 2020. These actions have resulted in escalating tensions between the U.S. and China and create the possibility that the Chinese government may take additional steps to retaliate against U.S. companies or industries. We cannot predict what additional actions the U.S. government may take with respect to Huawei beyond what is described above or to other of our customers, including modifications to or interpretations of Entity List restrictions, export restrictions, tariffs, or other trade limitations or barriers.

58

Our association with customers that are or become subject to U.S. regulatory scrutiny or export restrictions could negatively impact our business. Governmental actions such as these could subject us to actual or perceived reputational harm among current or prospective investors, suppliers or customers, customers of our customers, other parties doing business with us, or the general public. Any such reputational harm could result in the loss of investors, suppliers or customers, which could harm our business, financial condition, operating results or prospects. Further, if we fail to comply with any of these export regulations, we could be subject to civil, criminal, monetary and non-monetary penalties and costly consent decrees, which would lead to disruptions to our business, restrictions on our ability to export products and technology, and adversely affect our business and results of operation.

In addition, certain of our significant customers and suppliers have products that are subject to U.S. export controls, and therefore these customers and suppliers may also be subject to legal and regulatory consequences if they do not comply with applicable export control laws and regulations. Such regulatory consequences could disrupt our ability to obtain components from our suppliers, or to sell our products to major customers, which could significantly increase our costs, reduce our revenue and materially adversely affect our business, financial condition and results of operations.

The threat of increasing tariffs, particularly to goods traded between the United States and China, could materially and adversely affect our business and results of operations.

Since the beginning of 2018, there has been increasing rhetoric, in some cases coupled with legislative or executive action, from several U.S. and foreign leaders regarding instituting tariffs against foreign imports of certain materials. More specifically, since 2018, the United States and China applied or proposed to apply tariffs to certain of each other’s exports, and we expect these actions to continue for the foreseeable future. The institution of trade tariffs both globally and between the United States and China specifically carries the risk of negatively impacting overall economic conditions, which could have negative repercussions on our industry and our business. Furthermore, imposition of tariffs or new or revised export, import or doing-business regulations, including trade sanctions, could cause a decrease in the sales of our products to customers located in China or other customers selling to Chinese end users, which would directly impact our business and results of operations.

We face a number of risks related to our strategic transactions.

We have in the past made several acquisitions, including our acquisition of Oclaro in December 2018, and we expect to continue to expand and diversify our operations with additional acquisitions and strategic transactions. As we expand into new markets, we face competition not only from our existing competitors but also from new competitors, including existing companies with strong technological and sales positions in those markets. We may be unable to identify or complete prospective acquisitions for many reasons, including increasing competition from other potential acquirers, the effects of consolidation in our industries and potentially high valuations of acquisition candidates. Even if we do identify acquisitions or enter into agreements with respect to such acquisitions, we may not be able to complete the acquisition due to competition, regulatory requirements or restrictions or other reasons. In addition, applicable antitrust laws and other regulations may limit our ability to acquire targets or force us to divest an acquired business. If we are unable to identify suitable targets or complete acquisitions, our growth prospects may suffer, and we may not be able to realize sufficient scale and technological advantages to compete effectively in all markets.

In connection with acquisitions, risks to us and our business include:

•diversion of management’s attention from normal daily operations of the business;    

•unforeseen expenses, delays or conditions imposed upon the acquisition or transaction, including due to required regulatory approvals or consents, or fees that may be triggered upon a failure to consummate an acquisition or transaction for certain reasons;

•unanticipated changes in the combined business due to potential divestitures or other requirements imposed by antitrust regulators;

•unanticipated changes in the acquired business, including due to regulatory action or changes in the operating results or financial condition of the business;

•the inability to retain and obtain required regulatory approvals, licenses and permits;

•difficulties and costs in integrating the operations, technologies, products, IT and other systems, assets, facilities and personnel of the purchased businesses;

•loss of customers, suppliers or partners; and

•failure to consummate an acquisition resulting in negative publicity and impact on our stock price.

59

We have in the past, and may in the future, divest or reduce our investment in certain businesses or product lines from time to time. For example, in the fourth quarter of fiscal year 2019, we completed the divestiture of our Datacom module business in Japan, and in the second quarter of fiscal year 2020 we sold the assets associated with certain Lithium Niobate product lines manufactured by our San Donato, Italy site. Such divestitures involve risks, such as difficulty separating portions from our other businesses, distracting employees, incurring potential loss of revenue, negatively impacting margins, and potentially disrupting customer relationships. We may also incur significant costs associated with exit or disposal activities, related impairment charges, or both.

If we are unable to successfully manage any of these risks in relation to any future acquisitions or divestitures, our business, financial condition and results of operations could be adversely impacted.

We may be unable to successfully implement our acquisitions strategy or integrate acquired companies and personnel with existing operations.

To the extent we are successful in making acquisitions, we may be unsuccessful in implementing our acquisitions strategy, or integrating acquired companies or product lines and personnel with existing operations, or the integration may be more difficult or more costly than anticipated. Some of the risks that may affect our ability to integrate or realize any anticipated benefits from acquired companies, businesses or assets include those associated with:

•loss of customers, suppliers or partners;

•potential difficulties in completing projects associated with in-process R&D;

•an acquisition or strategic transaction may not further our business strategy as we expected or we may overpay for, or otherwise not realize the expected return on, our investments;

•we may face unanticipated liabilities or our exposure for known contingencies and liabilities may exceed our estimates;

•insufficient net revenue to offset increased expenses associated with acquisitions;

•unexpected losses of key employees of the acquired company, or inability to maintain our company culture;

•potential adverse effects on our ability to attract, recruit, retain, and motivate current and prospective employees;

•conforming the acquired company’s standards, processes, procedures and controls with our operations, including integrating Enterprise Resource Planning (“ERP”) systems and other key business applications;

•coordinating new product and process development;

•increasing complexity from combining operations;

•increasing the scope, geographic diversity and complexity of our operations;

•difficulties in integrating operations across different cultures and languages and to address the particular economic, currency, political, and regulatory risks associated with specific countries;

•difficulties in consolidating facilities and transferring processes and know-how;

•diversion of management’s attention from other business concerns;

•dilution of our current stockholders as a result of any issuance of equity securities as acquisition consideration;

•expenditure of cash that would otherwise be available to operate our business; and

•incurrence of indebtedness on terms that are unfavorable to us, limit our operational flexibility or that we are unable to repay.

In addition, following an acquisition, we may have difficulty forecasting the financial results of the combined company and the market price of our common stock could be adversely affected if the effect of any acquisitions on our consolidated financial results is dilutive or is below the market's or financial analysts' expectations, or if there are unanticipated changes in the business or financial performance of the target company or the combined company. Any failure to successfully integrate acquired businesses may disrupt our business and adversely impact our business, financial condition and results of operations.

Changes in demand and customer requirements for our products may reduce manufacturing yields, which could negatively impact our profitability.

60

Manufacturing yields depend on a number of factors, including the volume of production due to customer demand and the nature and extent of changes in specifications required by customers for which we perform design-in work. Changes in manufacturing processes required as a result of changes in product specifications, changing customer needs, introduction of new product lines and changes in contract manufacturers may reduce manufacturing yields, resulting in low or negative margins on those products. Moreover, an increase in the rejection rate of products during the quality control process, before, during or after manufacture, results in lower gross margins from lower yields and additional rework costs. Additionally, the duration and impact of COVID-19 could exacerbate factors that affect our manufacturing yields. Any reduction in our manufacturing yields will adversely affect our gross margins and could have a material impact on our operating results.

We may not be able to realize tax savings from our international tax structure, which could materially and adversely affect our operating results.

We initiated a new international corporate structure more closely aligned with our international operations during the third quarter of fiscal 2018. The new corporate structure is intended to reduce our overall effective tax rate through changes among our wholly-owned subsidiaries in how we use our intellectual property, and how we structure our international procurement and sales operations. The new structure includes legal entities located in jurisdictions with income tax rates lower than the U.S. statutory tax rate. The intercompany arrangements are intended to result in income earned by such entities in accordance with arm’s-length principles and commensurate with functions performed, risks assumed and ownership of valuable corporate assets. We have not yet operationalized the new structure to the full extent possible due to various factors including the acquisition of Oclaro in the second quarter of fiscal 2019. We are currently in the process of assessing the Oclaro transaction’s, and future transactions, impact to our tax structure and, depending on the outcome, we may make modifications to the new structure in order to achieve better tax and operational efficiency. If we are unable to fully adopt a new international structure, if substantial modifications to the new international structure or the way we operate our business are made in light of the Oclaro acquisition or for other reasons, such as future acquisitions or divestitures, if changes in domestic and international tax laws negatively impact the structure, if we do not operate our business consistent with the new structure and applicable tax provisions, if we fail to achieve our revenue and profit goals, or if the new international structure or our application of arm’s-length principles to intercompany arrangements is successfully challenged by the U.S. or foreign tax authorities, we may be unable to realize the anticipated tax savings which could materially and adversely affect our operating and financial results.

Changes in tax laws could have a material adverse effect on our business, cash flow, results of operations or financial conditions.

As a multinational corporation, we are subject to income taxes as well as non-income based taxes, in both the U.S. and various foreign jurisdictions. Significant uncertainties exist with respect to the amount of our tax liabilities, including those arising from potential changes in laws in the countries in which we do business and the possibility of adverse determinations with respect to the application of existing laws. Many judgments are required in determining our worldwide provision for income taxes and other tax liabilities, and we are under audit by various tax authorities, which often do not agree with positions taken by us on our tax returns. Any unfavorable resolution of these uncertainties may have a significant adverse impact on our tax rate.

Increasingly, countries around the world are actively considering or have enacted changes in relevant tax, accounting and other laws, regulations and interpretations. In particular, the Tax Cuts and Jobs Act (the “Tax Act”) contains many significant changes to the U.S. tax laws that affected the first three quarters of fiscal 2021, and which will continue to affect the remainder of our fiscal 2021 and fiscal years thereafter.

The reduction in the U.S. federal statutory rate is expected to positively impact our federal cash tax liability. However, the ultimate impact is subject to the effect of other complex provisions in the Tax Act (including the BEAT and GILTI), and it is possible that any impact of BEAT, GILTI, or other provisions of the Tax Act could significantly reduce, or outweigh, the benefit of the reduction in the U.S. federal statutory rate. The U.S. Treasury Department and the Internal Revenue Service (IRS), and other standards-setting bodies have issued and may continue to issue guidance on how the provisions of the Tax Act will be applied, which may be different from our interpretation. The Tax Act requires complex computations not previously required or produced, and significant judgments and assumptions in the interpretation of the law were made in producing our provisional estimates. We also anticipate that uncertainty in the application of the Tax Act to our ongoing operations as well as possible adverse future law changes attributable to changes in the U.S. political environment could have an adverse impact on our future tax rate. Other countries also continue to enact and consider enacting new laws, which could adversely affect us. The foregoing items could increase our future tax expense, could change our future intentions regarding reinvestment of foreign earnings, and could have a material adverse effect on our business, financial condition and results of operations.

61

The income and non-income tax regimes we are subject to or operate under are unsettled and may be subject to significant change. Changes in tax laws or tax rulings, or changes in interpretations of existing laws, could materially affect our financial position and results of operations. Many countries in Europe, as well as a number of other countries and organizations, have recently proposed or recommended changes to existing tax laws or have enacted new laws that could increase our tax obligations where we do business or require us to change the manner in which we operate our business. The Organization for Economic Cooperation and Development has been working on a set of internationally accepted tax rules as a part of a Base Erosion and Profit Sharing (BEPS) Project aimed at tax avoidance, and that the roll-out of BEPS action steps by various jurisdictions may change aspects of the existing framework under which our tax obligations are determined in many of the countries in which we do business.

Our subsidiary in Thailand currently operates under a tax holiday which will expire in fiscal 2025 unless extension is granted by the Thailand government and we continue to meet the requirements thereunder. If we do not meet the tax holiday requirements, if we are not granted an extension by the Thailand government, or if we decide not to apply for an extension of the tax holiday, income earned in Thailand will be subject to a higher statutory income tax rate, which may cause our effective tax rate to increase and reduce our liquidity and cash flow.

Our operating results may be subject to volatility due to fluctuations in foreign currency.

We are exposed to foreign exchange risks with regard to our international operations which may affect our operating results. Since we conduct business in currencies other than U.S. dollars but report our financial results in U.S. dollars, we face exposure to fluctuations in currency exchange rates. Although we price our products primarily in U.S. dollars, a portion of our operating expenses are incurred in foreign currencies. For example, a portion of our expenses are denominated in U.K. pound sterling, Chinese yuan and Thai baht. Fluctuations in the exchange rate between these currencies and other currencies in which we collect revenues and/or pay expenses could have a material effect on our future operating results. Recently, our exposure to foreign currencies has increased as our non-US manufacturing footprint has expanded. In addition to the acquisition of Oclaro, which increased our non-US manufacturing footprint, we continue to look for opportunities to leverage the lower cost of non-US manufacturing, including the United Kingdom, Thailand, and Japan. While these geographies are lower cost than the US and such concentration will in general lower our total cost to manufacture, this increase in concentration in non-US manufacturing will also increase the volatility of our results. If the value of the U.S. dollar depreciates relative to certain other foreign currencies, it would increase our costs as expressed in U.S. dollars. Conversely, if the U.S. dollar strengthens relative to other currencies, such strengthening could raise the relative cost of our products to non-U.S. customers, especially as compared to foreign competitors, and could reduce demand. The COVID-19 pandemic has had a significant impact on the exchange markets, which heightened this risk in the recent months, and we expect this higher level of volatility in foreign exchange markets will likely continue.

Our ability to develop, market, and sell products could be harmed if we are unable to retain or hire key personnel.

Our future success depends upon our ability to recruit and retain the services of executive, engineering, sales and marketing, and support personnel. The supply of highly qualified individuals, in particular engineers in very specialized technical areas, or sales people specializing in the service provider, enterprise and commercial laser markets, is limited and competition for such individuals is intense. Also, as a result of COVID-19, employees in our industries are increasingly able to work remotely, which has increased employee mobility and turnover, making it difficult for us to retain or hire employees. None of our officers or key employees is bound by an employment agreement for any specific term. The loss of the services of any of our key employees, the inability to attract or retain personnel in the future or delays in hiring required personnel and the complexity and time involved in replacing or training new employees, could delay the development and introduction of new products, and negatively impact our ability to market, sell, or support our products.

We may require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all.

62

We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including supporting the development and introduction of new products, addressing new markets, engaging in strategic transactions and partnerships, improving or expanding our operating infrastructure or acquiring complementary businesses and technologies. Investments, partnerships and acquisitions involve risks and uncertainties which could materially and adversely affect our operating and financial results. In March 2017, we issued and sold a total of $450 million in aggregate principal amount of 2024 Notes, and in December 2019, we issued and sold a total of $1,050 million in aggregate principal amount of 2026 Notes. We may in the future engage in additional equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity, equity-linked or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing we may secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly impaired, and our business may be harmed.

Our ability to hire and retain employees may be negatively impacted by changes in immigration laws, regulations and procedures.

Foreign nationals who are not U.S. citizens or permanent residents constitute an important part of our U.S. workforce, particularly in the areas of engineering and product development. Our ability to hire and retain these workers and their ability to remain and work in the United States are impacted by laws and regulations, as well as by procedures and enforcement practices of various government agencies and global events such as COVID-19 may interfere with our ability to hire or retain workers who require visas or entry permits. For example, in response to the pandemic, the U.S suspended entry of certain foreign nationals, which could impact our ability to hire and retain highly skilled employees from other countries. Changes in immigration laws, regulations or procedures, including those that have been and may be enacted in the future by the U.S. government, including current U.S. presidential administration, and in the United Kingdom or the European Union in connection with Brexit, may adversely affect our ability to hire or retain such workers, increase our operating expenses and negatively impact our ability to deliver our products and services.

Any failure, disruption or security breach of our information technology infrastructure or information management systems could have an adverse impact on our business and operations.

Our business depends significantly on effective and efficient information management systems, and the reliability and security of our information technology infrastructure are essential to the health and expansion of our business. For example, the information gathered and processed by our information management systems assists us in managing our supply chain, monitoring customer accounts, and protecting our proprietary and confidential business information, plans, trade secrets, and intellectual property, among other things. In addition, these systems may also contain personal data or other protected information about our employees, our customers’ employees, or others. We must continue to expand and update this infrastructure in response to our changing requirements as well as evolving security standards and risks.

In some cases, we may rely upon third-party providers of hosting, support and other services to meet our information technology requirements. Any failure to manage, expand and update our information technology infrastructure, including our ERP system and other applications, any failure in the extension implementation or operation of this infrastructure, or any failure by our hosting and support partners or other third-party service providers in the performance of their services could materially harm our business. In addition, we have partnered with third parties to support our information technology systems and to help design, build, test, implement and maintain our information management systems. Our merger, acquisition and divestiture activity may also require transitions to or from, and the integration of, various information management systems within our overall enterprise architecture, including our ERP system and other applications. Those systems that we acquire may also pose security risks of which we are unaware or unable to mitigate, particularly during the transition of these systems.

63

Like other companies, we are subject to ongoing attempts by malicious actors, including through hacking, malware, ransomware, denial-of-service attacks, social engineering, exploitation of internet-connected devices, and other attacks, to obtain unauthorized access or acquisition of confidential information or otherwise affect service reliability and threaten the confidentiality, integrity and availability of information on our systems. During the COVID-19 pandemic, the internet has experienced an increase in cyber threats in the form of phishing emails, malware attachments and malicious websites. We have been in the past, and may be in the future, subject to social engineering and other cybersecurity attacks, and these attacks may become more prevalent while our workforce is distributed following shelter-in-place orders particularly given the increased remote access to our networks and systems as a result. Further, our third-party service providers may have been and may be in the future subject to such attacks. In addition, actions by our employees, service providers, partners, contractors, or others, whether malicious or in error, could affect the security of our systems. Further, a breach of our information technology infrastructure could result in the misappropriation of intellectual property, business plans or trade secrets. Any failure of our systems or those of our third-party service providers could result in unauthorized access or acquisition of such proprietary information, and any actual or perceived security breach could cause significant damage to our reputation and adversely impact our relationships with our customers. Additionally, while our security systems are designed to maintain the physical security of our facilities and information systems, accidental or willful security breaches or other unauthorized access by third parties to our facilities or our information systems could lead to misappropriation of proprietary and confidential information.

Despite our implementation of security measures, our systems and those of our third-party service providers are vulnerable to damage from these types of attacks or errors. In addition, our systems may be impacted by natural disasters, terrorism or other similar disruptions. Any system failure, accident or security breach affecting us or our third-party providers could result in disruptions to our operations and loss of, or unauthorized access or damage to, our data or in inappropriate disclosure of confidential information. Any actual or alleged disruption to, or security breach affecting, our systems or those of our third-party partners could cause significant damage to our reputation, lead to theft of our protected intellectual property and trade secrets, result in legal obligations or liability, affect our relationships with our customers, and ultimately harm our business. In addition, we may be required to incur significant costs to protect against or mitigate damage caused by these disruptions or security breaches in the future.

Our revenues, operating results, and cash flows may fluctuate from period to period due to a number of factors, including unfavorable economic and market conditions, which makes predicting financial results difficult.

Spending on optical communication and laser products is subject to cyclical and uneven fluctuations, which could cause our financial results to fluctuate unpredictably. It can be difficult to predict the degree to which end-customer demand and the seasonality and uneven sales patterns of our OEM partners or other customers will affect our business in the future, particularly as we or they release new or enhanced products. While our fourth fiscal quarters are typically strongest, future buying patterns may differ from historical seasonality. Further, if our revenue mix changes, it may also cause results to differ from historical seasonality. Accordingly, our quarterly and annual revenues, operating results, cash flows, and other financial and operating metrics may vary significantly in the future, and the results of any prior periods should not be relied upon as an indication of future performance.

Adverse changes to and uncertainty in the global economy, particularly in light of the impacts of COVID-19 and a potential global recession resulting therefrom, may lead to decreased demand for our products, revenue fluctuations, and increased price competition for our products, and may increase the risk of excess and obsolete inventories and higher overhead costs as a percentage of revenue. Declines or uncertainty in particular geographic regions, such as China or Europe, may impact IT-related spending generally, and consequently may lead to lower growth or a decline in our markets. The loss or delay of orders from any of our significant customers could cause our revenue and profitability to suffer. The impact of economic challenges on the global financial markets could further negatively impact our operations by affecting the solvency of our customers, the solvency of our key suppliers or the ability of our customers to obtain credit to finance purchases of our products. If economic conditions deteriorate or remain uncertain, our financial condition and results of operations would likely be materially and adversely impacted.

64

If we have insufficient proprietary rights or if we fail to protect our rights, our business would be materially harmed.

We seek to protect our products and product roadmaps in part by developing and/or securing proprietary rights relating to those products, including patents, trade secrets, know-how and continuing technological innovation. Protecting against the unauthorized use of our products, technology and other proprietary rights is difficult, time-consuming and expensive, therefore the steps we take to protect our intellectual property may not adequately prevent misappropriation or ensure that others will not develop competitive technologies or products. Other companies may be investigating or developing technologies that are similar to our own. Additionally, there may be existing patents that we are unaware of, which could be pertinent to our business. It is not possible for us to know whether there are patent applications pending that our products might infringe upon since these applications are often not made publicly available until a patent is issued or published. It is possible that patents may not be issued from any of our pending applications or those we may file in the future and, if patents are issued, the claims allowed may not be sufficiently broad to deter or prohibit others from making, using or selling products that are similar to ours, or such patents could be invalidated or ruled unenforceable. We do not own patents in every country in which we sell or distribute our products, and thus others may be able to offer identical products in countries where we do not have intellectual property protections. In addition, the laws of some territories in which our products are or may be developed, manufactured or sold, including Europe, Asia-Pacific or Latin America, may not protect our products and intellectual property rights to the same extent as the laws of the United States. Any patents issued to us may be challenged, invalidated or circumvented. Additionally, we are currently a licensee for a number of third-party technologies including software and intellectual property rights from academic institutions, our competitors and others, and we are required to pay royalties to these licensors for the use thereof. In the future, if such licenses are unavailable or if we are unable to obtain such licenses on commercially reasonable terms, we may not be able to rely on such third-party technologies which could inhibit our development of new products, impede the sale of some of our current products, substantially increase the cost to provide these products to our customers, and could have a significant adverse impact on our operating results.

We also seek to protect our important trademarks by endeavoring to register them in certain countries. We have not registered our trademarks in every country in which we sell or distribute our products, and thus others may be able to use the same or confusingly similar marks in countries where we do not have trademark registrations. We have adopted Lumentum as a house trademark and trade name for our company, and are in the process of establishing rights in this name and brand. We have also adopted the Lumentum logo as a house trademark for our company, and are in the process of establishing rights in this brand. Trademarks associated with the Lumentum brand have been registered in the United States or other jurisdictions, however, the efforts we take to maintain registration and protect trademarks, including the Lumentum brand, may not be sufficient or effective. Although we have registered marks associated with the Lumentum brand, third parties may seek to oppose or otherwise challenge these registrations. There is the possibility that, despite efforts, the scope of the protection obtained for our trademarks, including the Lumentum brand, will be insufficient or that a registration may be deemed invalid or unenforceable in one or more jurisdictions throughout the world.

Further, a breach of our information technology infrastructure could result in the misappropriation of intellectual property, business plans or trade secrets. Any failure of our systems or those of our third-party service providers could result in unauthorized access or acquisition of such proprietary information, and any actual or perceived security breach could cause significant damage to our reputation and adversely impact our relationships with our customers.

65

Our products may be subject to claims that they infringe the intellectual property rights of others, the resolution of which may be time-consuming and expensive, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.

Lawsuits and allegations of patent infringement and violation of other intellectual property rights occur regularly in our industry. We have in the past received, and anticipate that we will receive in the future, notices from third parties claiming that our products infringe upon their proprietary rights, with two distinct sources of such claims becoming increasingly prevalent. First, large technology companies, including some of our customers and competitors, are seeking to monetize their patent portfolios and have developed large internal organizations that may approach us with demands to enter into license agreements. Second, patent-holding companies that do not make or sell products (often referred to as “patent trolls”) may claim that our products infringe upon their proprietary rights. We respond to these claims in the course of our business operations. The litigation or settlement of these matters, regardless of the merit of the claims, could result in significant expense and divert the efforts of our technical and management personnel, regardless of whether or not we are successful. If we are unsuccessful, we could be required to expend significant resources to develop non-infringing technology or to obtain licenses to the technology that is the subject of the litigation. We may not be successful in such development, or such licenses may not be available on commercially reasonable terms, or at all. Without such a license, or if we are the subject of an exclusionary order, our ability to make our products could be limited and we could be enjoined from future sales of the infringing product or products, which could adversely affect our revenues and operating results. Additionally, we often indemnify our customers against claims of infringement related to our products and may incur significant expenses to defend against such claims. If we are unsuccessful defending against such claims, we may be required to indemnify our customers against any damages awarded.

We also face risks that third parties may assert trademark infringement claims against us in one or more jurisdictions throughout the world related to our Lumentum and Oclaro brands and/or other trademarks and our exposure to these risks may increase as a result of acquisitions. The litigation or settlement of these matters, regardless of the merit of the claims, could result in significant expense and divert the efforts of our technical and management personnel, regardless of whether or not we are successful. If we are unsuccessful, trademark infringement claims against us could result in significant monetary liability or prevent us from selling some or all of our products or services under the challenged trademark. In addition, resolution of claims may require us to alter our products, labels or packaging, license rights from third parties, or cease using the challenged trademark altogether, which could adversely affect our revenues and operating results.

We face certain litigation risks that could harm our business.

We are now, and in the future we may become, subject to various legal proceedings and claims that arise in or outside the ordinary course of business. The results of legal proceedings are difficult to predict. Moreover, many of the complaints filed against us may not specify the amount of damages that plaintiffs seek, and we therefore may be unable to estimate the possible range of damages that might be incurred should these lawsuits be resolved against us. While we may be unable to estimate the potential damages arising from such lawsuits, certain of them assert types of claims that, if resolved against us, could give rise to substantial damages. Thus, an unfavorable outcome or settlement of one or more of these lawsuits could have a material adverse effect on our financial condition, liquidity and results of operations. Even if these lawsuits are not resolved against us, the uncertainty and expense associated with unresolved lawsuits could seriously harm our business, financial condition and reputation. Litigation is generally costly, time-consuming and disruptive to normal business operations. The costs of defending these lawsuits have been significant in the past, will continue to be costly and may not be covered by our insurance policies. The defense of these lawsuits could also result in continued diversion of our management’s time and attention away from business operations, which could harm our business. For additional discussion regarding litigation, see “Part II, Item 1. Legal Proceedings.”

Our products incorporate and rely upon licensed third-party technology, and if licenses of third-party technology do not continue to be available to us or are not available on terms acceptable to us, our revenues and ability to develop and introduce new products could be adversely affected.

We integrate licensed third-party technology into certain of our products. From time to time, we may be required to license additional technology from third-parties to develop new products or product enhancements. Third-party licenses may not be available or continue to be available to us on commercially reasonable terms. The failure to comply with the terms of any license, including free open source software, may result in our inability to continue to use such license. Our inability to maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new products and product enhancements, could potentially require us to develop substitute technology or obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could delay or prevent product shipment and harm our business, financial condition, and results of operations.

66

We are subject to laws and regulations worldwide including with respect to environmental matters, securities laws, privacy and data protection, compliance with which could increase our expenses and harm our operating results.

Our operations and our products are subject to various federal, state and foreign laws and regulations, including those governing pollution and protection of human health and the environment in the jurisdictions in which we operate or sell our products. These laws and regulations govern, among other things, wastewater discharges and the handling and disposal of hazardous materials in our products. Our failure to comply with current and future environmental or health or safety requirements could cause us to incur substantial costs, including significant capital expenditures, to comply with such environmental laws and regulations and to clean up contaminated properties that we own or operate. Such clean-up or compliance obligations could result in disruptions to our operations. Additionally, if we are found to be in violation of these laws, we could be subject to governmental fines or civil liability for damages resulting from such violations. These costs could have a material adverse impact on our financial condition or operating results.

From time to time new regulations are enacted, and it is difficult to anticipate how such regulations will be implemented and enforced. We continue to evaluate the necessary steps for compliance with regulations as they are enacted. These regulations include, for example, the Registration, Evaluation, Authorization and Restriction of Chemicals (“REACH”), the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive (“RoHS”) and the Waste Electrical and Electronic Equipment Directive (“WEEE”) enacted in the European Union which regulate the use of certain hazardous substances in, and require the collection, reuse and recycling of waste from, certain products we manufacture. These regulations and similar legislation may require us to re-design our products to ensure compliance with the applicable standards, for example by requiring the use of different types of materials, which could have an adverse impact on the performance of our products, add greater testing lead-times for product introductions or other similar effects. We believe we comply with all such legislation where our products are sold, and we continuously monitor these laws and the regulations being adopted under them to determine our responsibilities.

In addition, pursuant to Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC has promulgated rules requiring disclosure regarding the use of certain “conflict minerals” that are mined from the Democratic Republic of Congo and adjoining countries and procedures regarding a manufacturer’s efforts to prevent the sourcing of such minerals. Complying with these disclosure requirements involves substantial diligence efforts to determine the source of any conflict minerals used in our products and may require third-party auditing of our diligence process. These efforts may demand internal resources that would otherwise be directed towards operations activities.

Since our supply chain is complex, we may face reputational challenges if we are unable to sufficiently verify the origins of the conflict minerals used in our products. Additionally, if we are unable to satisfy those customers who require that all of the components of our products are determined to be conflict free, they may choose a competitor’s products which could materially impact our financial condition and operating results.

We are also subject to laws and regulations with respect to personal data we collect from our employees, customers, and others. These laws and regulations are subject to frequent modifications and updates and require ongoing supervision. For example, the European Union adopted a General Data Protection Regulation (“GDPR”) that became effective in May 2018, and has established new, and in some cases more stringent, requirements for data protection in Europe, and which provides for substantial penalties for noncompliance. We have made certain modifications to our practices in order to comply with these or other requirements, and may be required to make additional modifications in order to comply with these or other requirements relating to privacy and data protection in the future, each of which may require us to incur significant costs and expenses. Additionally, California enacted legislation in June 2018, the California Consumer Privacy Act (“CCPA”), which went into effect on January 1, 2020 and which, among other things, requires covered companies to provide new disclosures to California consumers. In November 2020, California passed the California Privacy Rights Act (“CPRA”), which will go into effect on January 1, 2023. The CPRA amends and augments the CCPA by expanding individuals’ rights and the obligations of businesses that handle personal data. Similar legislation has been proposed or adopted in other states. Aspects of the CCPA, CPRA and these other state laws and regulations, as well as their enforcement, remain unclear. The effects of the CCPA, CPRA and these other state laws and regulations are potentially significant, however, and may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. Laws and regulations relating to privacy and data protection continue to evolve in various jurisdictions, with existing laws and regulations subject to new and differing interpretations and new laws and regulations being proposed and adopted. It is possible that our practices may be deemed not to comply with those privacy and data protection legal requirements that apply to us now or in the future.

67

Further, in June 2016, a referendum was passed in the United Kingdom to leave the European Union, commonly referred to as “Brexit.” The United Kingdom officially left the European Union on January 31, 2020, with a transitional period that ended on December 31, 2020. Brexit created an uncertain political and economic environment in the United Kingdom and other European Union countries. For example, while the United Kingdom has enacted a Data Protection Bill that substantially implements GDPR, which became law in May 2018 and was the subject of statutory amendments in 2019 that further aligned it with the GDPR, there remains uncertainty with regard to how data transfers between the United Kingdom and the European Union will be regulated following Brexit.

Our failure or perceived failure to comply with any of the foregoing legal and regulatory requirements could result in increased costs for our products, monetary penalties, damage to our reputation, government inquiries and investigations, and legal action. Furthermore, the legal and regulatory requirements that are applicable to our business are subject to change from time to time, which increases our monitoring and compliance costs and the risk that we may fall out of compliance. Additionally, we may be required to ensure that our suppliers comply with applicable laws and regulations. If we or our suppliers fail to comply with such laws or regulations, we could face sanctions for such noncompliance, and our customers may refuse to purchase our products, which would have a material adverse effect on our business, financial condition and results of operations.

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, and Nasdaq listing requirements. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant resources, including accounting-related costs and significant management oversight.

Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could cause us to delay reporting of our financial results, be subject to one or more investigations or enforcement actions by state or federal regulatory agencies, stockholder lawsuits or other adverse actions requiring us to incur defense costs, pay fines, settlements or judgments. Any such failures could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our common stock and customer perception of our business may suffer. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the NASDAQ stock market.

Risks Related to Our Common Stock

Our stock price may be volatile and may decline regardless of our operating performance.

Our common stock is listed on the Nasdaq Global Select Market (“NASDAQ”) under the symbol “LITE”. The market price of our common stock has fluctuated, and may fluctuate significantly due to a number of factors, some of which may be beyond our control, including:

•general economic and market conditions and other external factors, particularly in light of the market volatility driven by the impact and duration of COVID-19;

•actual or anticipated fluctuations in our quarterly or annual operating results;

•changes in earnings estimates by securities analysts or our ability to meet those estimates;

•the operating and stock price performance of other comparable companies;

•a shift in our investor base;

•the financial performance of other companies in our industry, and of our customers;

•success or failure of our business strategy;

•credit market fluctuations which could negatively impact our ability to obtain financing as needed;

•changes in governmental regulation including taxation and tariff policies;

•changes in global political tensions that may affect business with our customers;

68

•announcements by us, competitors, customers, or our contract manufacturers of significant acquisitions or dispositions, such as our announcement related to the termination of the merger agreement with Coherent in March 2021, or overall movement toward industry consolidations among our customers and competitors;

•investor perception of us and our industry;

•changes in accounting standards, policies, guidance, interpretations or principles;

•litigation or disputes in which we may become involved;

•overall market fluctuations;

•sales of our shares by our officers, directors, or significant stockholders; and

•the timing and amount of dividends and share repurchases, if any.

In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business, results of operations, financial condition and cash flows.

Servicing our 2024 Notes and 2026 Notes may require a significant amount of cash, and we may not have sufficient cash flow or the ability to raise the funds necessary to satisfy our obligations under the 2024 Notes or 2026 Notes, and our current and future indebtedness may limit our operating flexibility or otherwise affect our business.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the 2024 Notes and 2026 Notes, or to make cash payments in connection with any conversion of the 2024 Notes, 2026 Notes or upon any fundamental change if holders of the applicable series of notes require us to repurchase their notes for cash, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to service our indebtedness and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring indebtedness or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. In addition, our existing and future indebtedness could have important consequences to our stockholders and significant effects on our business. For example, it could:

•make it more difficult for us to satisfy our debt obligations, including the 2024 Notes and the 2026 Notes;

•increase our vulnerability to general adverse economic and industry conditions;

•require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital and other general corporate purposes;

•limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

•restrict us from exploiting business opportunities;

•place us at a competitive disadvantage compared to our competitors that have less indebtedness; and

•limit our availability to borrow additional funds for working capital, capital expenditures, acquisitions, debt service requirements, execution of our business strategy or other general purposes.

Transactions relating to our 2024 Notes and 2026 Notes may dilute the ownership interest of existing stockholders, or may otherwise depress the price of our common stock.

69

If the 2024 Notes or the 2026 Notes are converted by holders of such series, we have the ability under the applicable indenture to deliver cash, equity, common stock, or any combination of cash or common stock, at our election upon conversion of the applicable series of convertible notes. If we elect to deliver common stock upon conversion of the 2024 Notes or the 2026 Notes, it would dilute the ownership interests of existing stockholders. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, certain holders of the 2024 Notes or the 2026 Notes may engage in short selling to hedge their position in the convertible notes. Anticipated future conversions of the 2024 Notes or 2026 Notes into shares of our common stock could depress the price of our common stock.

We do not expect to pay dividends on our common stock.

We do not currently expect to pay dividends on our common stock. The payment of any dividends to our stockholders in the future, and the timing and amount thereof, if any, is within the discretion of our board of directors. Our board of directors’ decisions regarding the payment of dividends will depend on many factors, such as our financial condition, earnings, capital requirements, potential debt service obligations or restrictive covenants, industry practice, legal requirements, regulatory constraints and other factors that our board of directors deems relevant.

In addition, because we are a holding company with no material direct operations, we are dependent on loans, dividends and other payments from our operating subsidiaries to generate the funds necessary to pay dividends on our common stock. However, our operating subsidiaries’ ability to make such distributions will be subject to their operating results, cash requirements and financial condition and the applicable provisions of Delaware law that may limit the amount of funds available for distribution. Our ability to pay cash dividends may also be subject to covenants and financial ratios related to existing or future indebtedness, and other agreements with third parties.

Certain provisions in our charter and Delaware corporate law could hinder a takeover attempt.

We are subject to the provisions of Section 203 of the DGCL which prohibits us, under some circumstances, from engaging in business combinations with some stockholders for a specified period of time without the approval of the holders of substantially all of our outstanding voting stock. Such provisions could delay or impede the removal of incumbent directors and could make more difficult a merger, tender offer or proxy contest involving us, even if such events could be beneficial, in the short-term, to the interests of our stockholders. In addition, such provisions could limit the price that some investors might be willing to pay in the future for shares of our common stock. Our certificate of incorporation and bylaws contain provisions providing for the limitations of liability and indemnification of our directors and officers, allowing vacancies on our board of directors to be filled by the vote of a majority of the remaining directors, granting our board of directors the authority to establish additional series of preferred stock and to designate the rights, preferences and privileges of such shares (commonly known as “blank check preferred”) and providing that our stockholders can take action only at a duly called annual or special meeting of stockholders, which may only be called by the chairman of the board of directors, the chief executive officer or the board of directors. These provisions may also have the effect of deterring hostile takeovers or delaying changes in control or changes in our management.

Our bylaws designate Delaware courts as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could discourage lawsuits against us or our directors and officers.

Our bylaws provide that, unless we consent in writing to an alternative forum, the state or federal courts of Delaware are the sole and exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting breach of fiduciary duty, or other wrongdoing, by our directors, officers or other employees to us or our stockholders; any action asserting a claim against Lumentum pursuant to the Delaware General Corporation Law or our certificate of incorporation or bylaws; any action asserting a claim against Lumentum governed by the internal affairs doctrine; or any action to interpret, apply, enforce or determine the validity of our certificate of incorporation or bylaws. This exclusive forum provision may limit the ability of our stockholders to bring a claim in a different judicial forum that such stockholders find favorable for disputes with us or our directors or officers, which may discourage such lawsuits against us or our directors and officers.

Alternatively, if a court outside of Delaware were to find this exclusive forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings described above, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

Description of Business and Summary of Significant Accounting Policies

Note 1. Description of Business and Summary of Significant Accounting Policies

Description of Business

Lumentum Holdings Inc. (“we,” “us,” “our”, “Lumentum” or the “Company”) is an industry-leading provider of optical and photonic products defined by revenue and market share addressing a range of end market applications including Optical Communications (“OpComms”) and Commercial Lasers (“Lasers”) for manufacturing, inspection and life-science applications. We seek to use our core optical and photonic technology, and our volume manufacturing capability, to expand into attractive emerging markets that benefit from advantages that optical or photonics-based solutions provide, including 3D sensing for consumer electronics and diode light sources for a variety of consumer and industrial applications. The majority of our customers tend to be original equipment manufacturers (“OEMs”) that incorporate our products into their products which then address end-market applications. For example, we sell fiber optic components that network equipment manufacturers (“NEMs”) assemble into communications networking systems, which they sell to network service providers, operators or enterprises with their own networks. Similarly, many of our customers for our Lasers products incorporate our products into tools they produce, which are used for manufacturing processes by their customers. For 3D sensing, we sell diode lasers to manufacturers of consumer electronics products for mobile, personal computing, gaming, and other applications who then integrate our devices within their products, for eventual resale to consumers and also into other industrial applications.

Basis of Presentation

The preparation of the condensed consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results may be different from the estimates. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are inventory valuation, revenue recognition, income taxes, and goodwill.

The COVID-19 pandemic has created and may continue to create significant uncertainty in global financial markets, which has disrupted and harmed, and may continue to disrupt and harm, the Company's business, financial condition, and results of operations. The extent of the impact of COVID-19 on the Company's operational and financial performance will depend on certain developments, including but not limited to the duration and spread of the outbreak, duration of local, state and federal issued public health orders in each jurisdiction where we operate or in which our customers and suppliers operate, impact on our customers and our sales cycles, impact on our supply chain and manufacturing partners, impact on our employees and impact on regional and worldwide economies and financial markets in general, all of which are uncertain and cannot be predicted.

Termination of Coherent Merger Agreement

On January 18, 2021, Lumentum and Coherent, Inc. (“Coherent”) entered into a merger agreement (the “merger agreement”), under which Lumentum would acquire all outstanding shares of Coherent common stock. As of the date of the merger agreement, the total transaction consideration was approximately $5.7 billion. In March 2021, Coherent terminated the merger agreement and paid Lumentum a termination fee of $217.6 million in accordance with the merger agreement. This gain was offset by $10.1 million of acquisition related expenses and the net amount is presented as “merger termination fee and related costs, net” in our condensed consolidated statements of operations for the three and nine months ended April 3, 2021.

Fiscal Years

We utilize a 52-53 week fiscal year ending on the Saturday closest to June 30th. Every fifth or sixth fiscal year will have a 53-week period. The additional week in a 53-week year is added to the third quarter, making such quarter consist of 14 weeks. Our fiscal 2021 is a 53-week year ending on July 3, 2021, with the quarter ended April 3, 2021 being a 14-week quarterly period. Our fiscal 2020 was a 52-week year that ended on June 27, 2020, with the quarter ended March 28, 2020 being a 13-week quarterly period.

Principles of Consolidation

These interim unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated in consolidation. 

Accounting PoliciesThe accompanying condensed consolidated financial statements and accompanying related notes should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended June 27, 2020. There have been no significant changes to these policies during the nine months ended April 3, 2021, except for the removal of the long-lived asset valuation policy and the updates resulting from the adoption of Topic 326, as discussed in “Note 2. Recently Issued Accounting Pronouncements”.

Accounting Changes and Error Corrections [Abstract]

Recently Issued Accounting Pronouncements

Note 2. Recently Issued Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on transfers between Level 1 and Level 2, valuation processes of Level 3 fair value measurements, and the categorization by level for items that are not measured at fair value, but for which the fair value is required to be disclosed. We adopted ASU 2018-13 in the first quarter of fiscal 2021 with no impact to our condensed consolidated financial statements.

In August 2018, FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This standard requires capitalization of the implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Further, the standard also requires the Company to expense the capitalized implementation costs of a hosting arrangement over the term of the hosting arrangement. We adopted ASU 2018-15 in the first quarter of fiscal 2021 with no impact to our condensed consolidated financial statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and a subsequent amendment, ASU 2018-19 (collectively, Topic 326). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. We adopted ASU 2016-13 using the modified-retrospective approach in the first quarter of fiscal 2021 with no material impact to our condensed consolidated financial statements.

With the adoption of Topic 326, we are now assessing whether unrealized losses have resulted from a credit loss or other factors. We believe none of our unrealized losses on available-for-sale investments were other-than temporary or were attributable to credit losses as of April 3, 2021 and June 27, 2020. We review our available-for-sale investments on a quarterly basis to identify a potential other-than-temporary impairment. The investments with unrealized losses consisted primarily of corporate debt securities, and given the extent of the unrealized loss positions, the issuers' high credit ratings and the near-term market conditions, we believe our unrealized losses are temporary. We also do not have an intent to sell our investments and would not be required to sell them before they recover.

The adoption of Topic 326 did not significantly change our approach to the valuation of trade receivables. We determine whether there is an expected loss on our accounts receivable by reviewing all available data, including our customers' latest available financial statements, their credit standing and historical collection experience, as well as current and future market and economic conditions. As of April 3, 2021 and June 27, 2020, the allowance for credit losses on our trade receivables was $1.8 million and $1.8 million, respectively.

Accounting Pronouncements Not Yet Effective

In August 2020, FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for convertible instruments by removing the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. As a result, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost. Also, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and the treasury stock method will be no longer available. The new guidance is effective for fiscal years beginning after December 15, 2021, with early adoption permitted no earlier than fiscal years beginning after December 15, 2020. ASU 2020-06 is effective for us in our first quarter of fiscal year 2023. We are currently evaluating the impact of ASU 2020-06 on our condensed consolidated financial statements.

In December 2019, FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), which is intended to simplify various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and which also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for us at the beginning of fiscal year 2022, including interim periods within that reporting period, although early adoption is permitted. We are currently evaluating the impact of ASU 2019-12 on our condensed consolidated financial statements.

In August 2018, FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Topic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies the disclosure requirements for defined benefit pension plans and other post-retirement benefit plans. The new guidance is effective for fiscal years ending after December 15, 2020, with early adoption permitted. ASU 2018-14 should be applied retrospectively to all periods presented and is effective for us in our fourth quarter of fiscal year 2021 as ASU 2018-14 does not amend the interim disclosure requirements. We are currently evaluating the impact of ASU 2018-14 on our condensed consolidated financial statements.

Net income per share:
Basic	$	2.97	$	0.58	$	4.97	$	1.84
Diluted	$	2.85	$	0.56	$	4.78	$	1.80

Potentially dilutive common shares result from the assumed exercise of outstanding stock options, assumed vesting of outstanding equity awards, assumed issuance of stock under the employee stock purchase plan, and assumed conversion of our outstanding convertible notes, all using the treasury stock method.

We have the ability and intent to settle the face value of our convertible notes in cash. Therefore, we use the treasury stock method for calculating the dilutive impact of the convertible notes. The 2026 Notes (as defined in Note 9) will have no impact on diluted earnings per share until the average price of our common stock exceeds the conversion price of $99.29. The potentially dilutive shares resulting from the 2024 Notes (as defined in Note 9) were included in the calculation of diluted income per share for the three and nine months ended April 3, 2021 since the average price of our common stock exceeded the conversion price of $60.62. Refer to “Note 9. Debt” for further discussion.

Anti-dilutive potential shares are excluded from the calculation of diluted earnings per share if their exercise price exceeded the average market price during the period or the share-based awards were determined to be anti-dilutive based on applying the treasury stock method. Anti-dilutive shares excluded from the calculation of diluted earnings per share were not material and were 0.5 million shares for the three and nine months ended April 3, 2021, respectively. Anti-dilutive shares excluded from the calculation of diluted earnings per share were not material for each of the three and nine months ended March 28, 2020, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 5. Fair Value Measurements

We determine fair value based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value:

Level 1:	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2:	Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.
Level 3:	Inputs are unobservable inputs based on our assumptions.

The fair value of our Level 1 financial instruments, such as money market funds and U.S. Treasury securities, which are traded in active markets, is based on quoted market prices for identical instruments. The fair value of our Level 2 fixed income securities is obtained from an independent pricing service, which may use quoted market prices for identical or comparable instruments or model driven valuations using observable market data or inputs corroborated by observable market data. Our marketable securities are held by custodians who obtain investment prices from a third-party pricing provider that incorporates standard inputs in various asset price models. Our procedures include controls to ensure that appropriate fair values are recorded, including comparing the fair values obtained from our pricing service against fair values obtained from another independent source.

Financial assets measured at fair value on a recurring basis are summarized below (in millions):

Financial Instruments Not Recorded at Fair Value on a Recurring Basis

We report our financial instruments at fair value with the exception of the 2026 Notes and the 2024 Notes. The estimated fair value of the notes was determined based on the trading price of the notes as of the last day of trading for the period. We consider the fair value of the notes to be a Level 2 measurement as they are not actively traded in markets.

The carrying amounts and estimated fair values of the 2026 Notes and the 2024 Notes are as follows for the periods presented (in millions):

	April 3, 2021				June 27, 2020
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
2026 Notes	$	778.9	$	1,240.5	$	749.7	$	1,070.2
2024 Notes	385.3		730.9		370.6		620.0
	$	1,164.2	$	1,971.4	$	1,120.3	$	1,690.2

Assets Measured at Fair Value on a Non-Recurring Basis

We periodically review our intangible and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and its eventual disposition. If not recoverable, an impairment loss would be calculated based on the excess of the carrying amount over the fair value.

Management utilizes various valuation methods, including an income approach, a market approach and a cost approach, to estimate the fair value of intangibles and other long-lived assets. During the annual impairment testing performed in the fourth quarter of fiscal 2020, we concluded that our intangible and other long-lived assets were not impaired. We review our intangible and other long-lived assets for impairment at least annually in the fourth quarter of each fiscal year, absent any interim indicators of impairment.

Leases

Note 7. Leases

We lease certain real and personal property from unrelated third parties under non-cancellable operating leases that expire at various dates through fiscal 2033. These operating leases are mainly for administrative offices, research-and-development and manufacturing facilities, as well as sales offices in various countries around the world. Certain leases require us to pay property taxes, insurance and routine maintenance, and include escalation clauses. Many leases include one or more options to renew. We do not assume renewals in our determination of the lease term unless the renewals are deemed to be reasonably assured at lease commencement.

We also have various finance leases of servers and certain other equipment for our operations. These arrangements are typically for two to four years.

As of April 3, 2021, we sublease certain floors of our offices in the United Kingdom, the United States, Canada, and Japan. These subleases will expire at various dates by fiscal year 2023. We anticipate receiving approximately $3.6 million in sublease income over the next two years.

Goodwill

The following table presents our goodwill balance by the reportable segments as of April 3, 2021 and June 27, 2020 (in millions):

	Optical Communications		Commercial Lasers		Total
Balance as of April 3, 2021 and June 27, 2020	$	363.5	$	5.4	$	368.9

Impairment of Goodwill

We review goodwill for impairment during the fourth quarter of each fiscal year or more frequently if events or circumstances indicate that an impairment loss may have occurred. In the fourth quarter of fiscal 2020, we completed the annual impairment test of goodwill, which indicated there was no goodwill impairment. There were no indicators of goodwill impairment during the three and nine months ended April 3, 2021.

Other Intangibles

The intangible assets are amortized on a straight-line basis over the estimated useful lives, except for customer relationships and order backlog, which are amortized using an accelerated method of amortization over the expected customer lives, which more accurately reflects the pattern of realization of economic benefits expected to be obtained. Acquired developed technologies and order backlog are amortized to cost of sales and customer relationships is amortized to selling, general and administrative. In-process research and development (“IPR&D”) is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. When an IPR&D project is completed, the IPR&D is reclassified as an amortizable purchased intangible asset and amortized over the asset’s estimated useful life.

The following tables present details of our other intangibles as of the periods presented (in millions, except for weighted average remaining amortization period):

April 3, 2021	Gross Carrying Amounts		Accumulated Amortization		Net Carrying Amounts		Weighted average remaining amortization period (years)
Acquired developed technologies	$	390.3	$	(222.3)	$	168.0	3.2

Total intangible assets	$	560.0	$	(296.8)	$	263.2

The table above excludes fully amortized intangibles of $5.5 million that were written off against accumulated amortization during the three and nine months ended April 3, 2021.

During the three and nine months ended April 3, 2021, we completed our remaining IPR&D projects and therefore reclassified $10 million from IPR&D to acquired developed technologies. This amount will be amortized over the assets’ estimated useful life of 3 years.

During the nine months ended April 3, 2021, we purchased intellectual property from a third party for a total consideration of $10 million. These intangible assets have an estimated useful life of 5 years.

June 27, 2020	Gross Carrying Amounts		Accumulated Amortization		Net Carrying Amounts		Weighted average remaining amortization period (years)

Convertible Notes

2026 Notes

In December 2019, we issued $1,050 million in aggregate principal amount of the 2026 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The 2026 Notes are governed by an indenture between the Company and U.S. Bank National Association (the “2026 Indenture”). We used approximately $196 million of the net proceeds of the offering to repay in full all amounts outstanding under our term loan credit facility, and a portion of the net proceeds of the offering to purchase approximately $200 million of our common stock concurrently with the pricing of the offering in privately negotiated transactions. The 2026 Notes are unsecured and do not contain any financial covenants, restrictions on dividends, incurrence of senior debt or other indebtedness, or the issuance or repurchase of securities by us.

The 2026 Notes will bear interest at a rate of 0.50% per year, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2020. The 2026 Notes will mature on December 15, 2026, unless earlier redeemed, repurchased by us, or converted pursuant to their terms.

The initial conversion rate is 10.0711 shares of common stock per $1,000 principal amount of the 2026 Notes (which is equivalent to an initial conversion price of approximately $99.29 per share). The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, upon the occurrence of a make-whole fundamental change or our issuance of a notice of redemption, we will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert the 2026 Notes in connection with such make-whole fundamental change or notice of redemption.

Prior to the close of business on the business day immediately preceding September 15, 2026, holders of the 2026 Notes may convert their 2026 Notes only under certain circumstances discussed in detail in our Annual Report on Form 10-K for the year ended June 27, 2020.

2024 Notes

In March 2017, we issued $450 million of the 2024 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 2024 Notes are governed by an indenture between the Company, as the issuer, and U.S. Bank National Association, as trustee (the “2024 Indenture”). The 2024 Notes are unsecured and do not contain any financial covenants, restrictions on dividends, incurrence of senior debt or other indebtedness, or the issuance or repurchase of securities by us.

The 2024 Notes bear interest at a rate of 0.25% per year. Interest on the 2024 Notes is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2017. The 2024 Notes will mature on March 15, 2024, unless earlier repurchased by us or converted pursuant to their terms.

The initial conversion rate of the 2024 Notes is 16.4965 shares of common stock per $1,000 principal amount of 2024 Notes, which is equivalent to an initial conversion price of approximately $60.62 per share, a 132.5% premium to the fair market value at the date of issuance. Prior to the close of business on the business day immediately preceding December 15, 2023, each holder of the 2024 Notes may convert their 2024 Notes only under certain circumstances discussed in detail in our Annual Report on Form 10-K for the year ended June 27, 2020.

Our convertible notes consisted of the following components as of the periods presented (in millions):

Liability component:	April 3, 2021				June 27, 2020
	2024 Notes (1)		2026 Notes		2024 Notes (1)		2026 Notes
Principal	$	450.0	$	1,050.0	$	450.0	$	1,050.0
Unamortized debt discount and debt issuance costs	(64.7)		(271.1)		(79.4)		(300.3)
Net carrying amount of the liability component	$	385.3	$	778.9	$	370.6	$	749.7

(1) Since the closing price of our stock exceeded $78.80 (or 130% of the conversion price of $60.62) for 20 of the last 30 trading days of the third quarter of fiscal 2021, the 2024 Notes have become convertible at the option of the holders. Therefore, the debt component of our 2024 Notes as of April 3, 2021 has been classified as current liabilities in our condensed consolidated balance sheet.

If the closing price of our stock exceeds $129.08 (or 130% of the conversion price of $99.29) for 20 of the last 30 trading days of any future quarter, our 2026 Notes would also become convertible at the option of the holders and the debt component would be reclassified to current liabilities in our condensed consolidated balance sheet.

The following table sets forth interest expense information related to the convertible notes for the periods presented (in millions):

	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020

Total convertible notes payments	$	453.4	$	1,081.5	$	1,534.9

The principal balances of our Notes are reflected in the payment periods in the table above based on their respective contractual maturities. During the three and nine months ended April 3, 2021, we received conversion requests for less than $0.1 million principal amount of the 2024 Notes, which will be settled in cash in the fourth quarter of fiscal 2021.

Term Loan Facility

In December 2018, concurrent with the closing of the Oclaro merger, we entered into a credit agreement providing for a term loan facility (the “Term Loan Facility”) in an aggregate principal amount of $500.0 million and we drew in full the term loans available under the Term Loan Facility on the closing date of the Oclaro merger. In the second quarter of fiscal 2020, we repaid, in full, all amounts outstanding under our Term Loan Facility. During the nine months ended March 28, 2020, we incurred $18.1 million of interest expense on this Term Loan Facility, which includes an $8.0 million loss on the early extinguishment of debt.

Other Interest Expense

For the nine months ended March 28, 2020, we also recorded $0.1 million interest expense related to our finance leases.

Restructuring and Related Charges

Note 11. Restructuring and Related Charges

We have initiated various strategic restructuring actions primarily intended to reduce costs, consolidate our operations, rationalize the manufacturing of our products and align our business in response to market conditions.

The following table summarizes the activity of restructuring and related charges during the three and nine months ended April 3, 2021 and March 28, 2020 (in millions):

Balance as of end of period	$	4.2	$	2.6	$	4.2	$	2.6

During the three and nine months ended April 3, 2021, we recorded restructuring and related charges of $2.9 million and $3.1 million, respectively, in our condensed consolidated statements of operations. The charges were mainly attributable to severance charges associated with the decision to cease manufacturing of certain products in San Jose, California.

During the three and nine months ended March 28, 2020, we recorded $2.7 million and $4.9 million, respectively, in restructuring and related charges in our condensed consolidated statements of operations. The charges were mainly attributable to severance charges associated with the decision to move certain manufacturing from San Jose, California to our facility in Thailand and other third party vendors.

Any changes in the estimates of executing our restructuring activities will be reflected in our future results of operations.

Income Tax Disclosure [Abstract]

Income Taxes

Note 12. Income Taxes

Our tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, we update our estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, we make a cumulative adjustment in such period. Our quarterly tax provision and estimate of our annual effective tax rate are subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income relates, changes in how we do business, and tax law developments.

We recorded a tax provision of $27.4 million and $58.8 million for the three and nine months ended April 3, 2021, respectively. Our tax provision for the three months ended April 3, 2021 includes a discrete tax expense of $16.8 million mainly associated with the Coherent termination fee, partially offset by currency re-measurement of certain tax related accounts and return-to-provision differences. Our estimated effective tax rate for fiscal 2021 differs from the 21% U.S. statutory rate primarily due to the earnings of our foreign subsidiaries being taxed at rates that differ from the U.S. statutory rate as well as the U.S. federal R&D tax credits, partially offset by the income tax expense from non-deductible stock-based compensation and the tax effect of Global Intangible Low-Taxed Income (“GILTI”), net of benefit for foreign tax credits, and subpart F inclusion.

As of April 3, 2021, we had $26.9 million of unrecognized tax benefits, which, if recognized, would affect the effective tax rate. We are subject to examination of income tax returns by various domestic and foreign tax authorities. The timing of commencement, resolution and closure of tax audits is highly unpredictable. Although it is possible that certain ongoing tax audits may be concluded within the next 12 months, we cannot reasonably estimate the impact to tax expense and net income from tax exams that could be resolved or closed within the next 12 months. Subject to audit timing and uncertainty, we expect our unrecognized tax benefit amount that could affect the effective tax rate to decrease by $4.8 million over the next 12 months.

We believe that we have adequately provided under GAAP for potential outcomes related to our tax audits. However, there can be no assurances as to the possible outcomes or any related financial statement effect thereof.

Description of Lumentum Stock-Based Benefit Plans

Equity Incentive Plan

As of April 3, 2021, we had 2.2 million shares subject to restricted stock units and performance stock units issued and outstanding under the 2015 Equity Incentive Plan (the “2015 Plan”). Restricted stock units and performance stock units are performance-based, time-based or a combination of both. The fair value of these grants is based on the closing market price of our common stock on the date of award.

As of April 3, 2021, 2.3 million shares of common stock under the 2015 Plan were available for grant.

Replacement Awards

In connection with the acquisition of Oclaro, we issued equity awards to Oclaro employees (“replacement awards”) in exchange for their Oclaro equity awards. As of April 3, 2021, we had 0.1 million of unvested shares subject to restricted stock units under the replacement awards.

Restricted Stock Units

Restricted stock units (“RSUs”) under the 2015 Plan are grants of shares of our common stock, the vesting of which is based on the requisite service requirement. Generally, our RSUs are subject to forfeiture and are expected to vest over one to four years. For annual refresh grants, RSUs generally vest ratably on an annual, or combination of annual and quarterly, basis over three years.

Performance Stock Units

Performance stock units (“PSUs”) under the 2015 Plan are grants of shares of our common stock that vest upon the achievement of certain performance and service conditions. We begin recognizing compensation expense when we conclude that it is probable that the performance conditions will be achieved. We reassess the probability of vesting at each reporting period and adjust our compensation cost based on this probability assessment. Our PSUs are subject to risk of forfeiture until performance and service conditions are satisfied and generally vest over three years.

Employee Stock Purchase Plan

Our 2015 Employee Stock Purchase Plan (the “2015 Purchase Plan”) provides eligible employees with the opportunity to acquire an ownership interest in the Company through periodic payroll deductions and provides a 15% purchase price discount as well as a 6-month look-back period. The 2015 Purchase Plan is structured as a qualified employee stock purchase plan under Section 423 of the Internal Revenue Code of 1986, as amended. The 2015 Purchase Plan will terminate upon the date on which all shares available for issuance have been sold. Of the 3.0 million shares authorized under the 2015 Purchase Plan, 1.7 million shares remained available for issuance as of April 3, 2021.

Stock-Based Compensation

The impact on our results of operations of recording stock-based compensation by function for the three and nine months ended April 3, 2021 and March 28, 2020 was as follows (in millions):

Commitments and Contingencies

Note 14. Commitments and Contingencies

Purchase Obligations

Purchase obligations of $224.9 million as of April 3, 2021, represent legally-binding commitments to purchase inventory and other commitments made in the normal course of business to meet operational requirements.

Although open purchase orders are considered enforceable and legally binding, the terms generally allow the option to cancel, reschedule and adjust the requirements based on our business needs prior to the delivery of goods or performance of services. Obligations to purchase inventory and other commitments are generally expected to be fulfilled within one year.

We depend on a limited number of contract manufacturers, subcontractors and suppliers for raw materials, packages and standard components. We generally purchase these single or limited source products through standard purchase orders or one-year supply agreements and have no significant long-term guaranteed supply agreements with such vendors. While we seek to maintain a sufficient safety stock of such products and maintain on-going communications with our suppliers to guard against interruptions or cessation of supply, our business and results of operations could be adversely affected by a stoppage or delay of supply, substitution of more expensive or less reliable products, receipt of defective parts or contaminated materials, increases in the price of such supplies, or our inability to obtain reduced pricing from our suppliers in response to competitive pressures.

Product Warranties

We provide reserves for the estimated costs of product warranties at the time revenue is recognized. We typically offer a twelve month warranty for most of our products. However, in some instances depending upon the product, product components or application of our products by the end customer, our warranties can vary and generally range from six months to five years. We estimate the costs of our warranty obligations on an annualized basis based on our historical experience of known product failure rates, use of materials to repair or replace defective products and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise with specific products. We assess the adequacy of our recorded warranty liabilities and adjust the amounts as necessary.

The following table presents the changes in our warranty reserve during the three and nine months ended April 3, 2021 and March 28, 2020 (in millions):

	Three Months Ended				Nine Months Ended
	April 3, 2021		March 28, 2020		April 3, 2021		March 28, 2020
Balance as of beginning of period	$	5.7	$	6.8	$	5.0	$	7.5
Provision for warranty	1.7		0.7		5.8		2.5
Utilization of reserve	(1.8)		(2.1)		(5.2)		(4.6)
Balance as of end of period	$	5.6	$	5.4	$	5.6	$	5.4

Environmental Liabilities

Our research and development (“R&D”), manufacturing and distribution operations involve the use of hazardous substances and are regulated under international, federal, state and local laws governing health and safety and the environment. We apply strict standards for protection of the environment and occupational health and safety to sites inside and outside the United States, even if not subject to regulations imposed by foreign governments. We believe that our properties and operations at our facilities comply in all material respects with applicable environmental laws and occupational health and safety laws. However, the risk of environmental liabilities cannot be completely eliminated and there can be no assurance that the application of environmental and health and safety laws will not require us to incur significant expenditures. We are also regulated under a number of international, federal, state and local laws regarding recycling, product packaging and product content requirements. The environmental, product content/disposal and recycling laws are gradually becoming more stringent and may cause us to incur significant expenditures in the future.

Legal Proceedings

We are subject to a variety of claims and suits that arise from time to time in the ordinary course of our business. While management currently believes that resolving claims against us, individually or in the aggregate, will not have a material adverse impact on our financial position, results of operations or statements of cash flows, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. We accrue for loss contingencies when it is both probable that we will incur the loss and when we can reasonably estimate the amount of the loss or range of loss.

Merger Litigation

In connection with our acquisition of Oclaro, seven lawsuits were filed by purported stockholders of Oclaro challenging the proposed merger (the “Merger”). Two of the seven suits were putative class actions filed against Oclaro, its directors, Lumentum, Prota Merger Sub, Inc. and Prota Merger, LLC: Nicholas Neinast v. Oclaro, Inc., et al., No. 3:18-cv-03112-VC, in the United States District Court for the Northern District of California (filed May 24, 2018) (the “Neinast Lawsuit”); and Adam Franchi v. Oclaro, Inc., et al., No. 1:18-cv-00817-GMS, in the United States District Court for the District of Delaware (filed June 9, 2018) (the “Franchi Lawsuit”). Both the Neinstat Lawsuit and the Franchi Lawsuit were voluntarily dismissed with prejudice.

The other five suits, styled as Gerald F. Wordehoff v. Oclaro, Inc., et al., No. 5:18-cv-03148-NC (the “Wordehoff Lawsuit”), Walter Ryan v. Oclaro, Inc., et al., No. 3:18-cv-03174-VC (the “Ryan Lawsuit”), Jayme Walker v. Oclaro, Inc., et al., No. 5:18-cv-03203-EJD (the “Walker Lawsuit”), Kevin Garcia v. Oclaro, Inc., et al., No. 5:18-cv-03262-VKD (the “Garcia Lawsuit”), and SaiSravan B. Karri v. Oclaro, Inc., et al., No. 3:18-cv-03435-JD (the “Karri Lawsuit” and, together with the other six lawsuits, the “Lawsuits”), were filed in the United States District Court for the Northern District of California on May 25, 2018, May 29, 2018, May 30, 2018, May 31, 2018, and June 9, 2018, respectively. These five Lawsuits named Oclaro and its directors as defendants only and did not name Lumentum. The Wordehoff, Ryan, Walker, and Garcia Lawsuits have been voluntarily dismissed, and the Wordehoff, Ryan, and Walker dismissals were with prejudice. The Karri Lawsuit has not yet been dismissed. The Ryan Lawsuit was, and the Karri Lawsuit is, a putative class action.

The Lawsuits generally alleged, among other things, that Oclaro and its directors violated Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder by disseminating an incomplete and misleading Form S-4, including proxy statement/prospectus. The Lawsuits further alleged that Oclaro’s directors violated Section 20(a) of the Exchange Act by failing to exercise proper control over the person(s) who violated Section 14(a) of the Exchange Act.

The remaining Lawsuit (the Karri Lawsuit) currently purports to seek, among other things, damages to be awarded to the plaintiff and any class, if a class is certified, and litigation costs, including attorneys’ fees. A lead plaintiff and counsel has been selected, and an amended complaint was filed on April 15, 2019, which also names Lumentum as a defendant. A motion to dismiss the amended complaint was granted in part and denied in part by the court on October 8, 2020. On December 1, 2020, defendants answered the amended complaint. On December 23, 2020, defendants filed a motion for leave to file a motion for reconsideration of the Court’s October 8 order on the motion to dismiss, which was denied on January 29, 2021. The Karri Lawsuit remains pending with the parties currently in discovery. Defendants intend to defend the Karri Lawsuit vigorously.

Indemnifications

In the normal course of business, we enter into agreements that contain a variety of representations and warranties and provide for general indemnification. Exposure under these agreements is unknown because claims may be made against us in the future and we may record charges in the future as a result of these indemnification obligations. As of April 3, 2021, we did not have any material indemnification claims that were probable or reasonably possible.

Audit Proceedings

We are under audit by various domestic and foreign tax authorities with regards to income tax and indirect tax matters. In some, although not all cases, we have reserved for potential adjustments to our provision for income taxes and accrual of indirect taxes that may result from examinations by these tax authorities or final outcomes in judicial proceedings, and we believe that the final outcome of these examinations, agreements or judicial proceedings will not have a material effect on our results of operations. If events occur which indicate payment of these amounts is unnecessary, the reversal of the liabilities would result in the recognition of benefits in the period we determine the liabilities are no longer necessary. If our estimates of the federal, state, and foreign income tax liabilities and indirect tax liabilities are less than the ultimate assessment, it could result in a further charge to expense.

Segment Reporting [Abstract]

Operating Segments and Geographic Information

Note 15. Operating Segments and Geographic Information

Our chief executive officer is our Chief Operating Decision Maker (“CODM”). The CODM allocates resources to the segments based on their business prospects, competitive factors, net revenue and gross margin. We do not track all of our property, plant and equipment by operating segments. The geographic identification of these assets is set forth below.

We are an industry leading provider of optical and photonic products defined by revenue and market share addressing a range of end-market applications including optical communications and commercial lasers. We have two operating segments, Optical Communications, which we refer to as OpComms, and Commercial Lasers, which we refer to as Lasers. Our OpComms products address the following markets: telecommunications and data communications (“Telecom and Datacom”), and consumer and industrial (“Consumer and Industrial”), and include product lines from the acquisition of Oclaro. The two operating segments were primarily determined based on how the CODM views and evaluates our operations. Operating results are regularly reviewed by the CODM to make decisions about resources to be allocated to the segments and to assess their performance. Other factors, including market separation and customer specific applications, go-to-market channels, products and manufacturing, are considered in determining the formation of these operating segments.

OpComms

Our OpComms products include a wide range of components, modules and subsystems to support customers including carrier networks for access (local), metro (intracity), long-haul (city-to-city and worldwide) and submarine (undersea) applications. Additionally, our products address enterprise, cloud, and data center applications, including storage-access networks (“SANs”), local-area networks (“LANs”) and wide-area networks (“WANs”). These products enable the transmission and transport of video, audio and data over high-capacity fiber-optic cables. We maintain leading positions in these fast growing OpComms markets through our extensive product portfolio, including reconfigurable optical add/drop multiplexers (“ROADMs”), coherent dense wavelength division multiplexing (“DWDM”) pluggable transceivers, and tunable small form-factor pluggable transceivers. We also sell laser chips for use in the manufacture of high-speed Datacom transceivers.

In the Consumer and Industrial market, our OpComms diode laser products include vertical cavity surface emitting lasers (“VCSELs”) and edge emitting lasers. In the Consumer end-market, our laser light sources are integrated into 3D sensing cameras which are used in applications in mobile devices, gaming, payment kiosks, computers, and other consumer electronics devices. Applications include biometric identification, computational photography, virtual and augmented reality, and natural user interfaces. Emerging applications for our lasers include automotive safety systems, LiDAR for advanced driver assistance systems in automobiles and autonomous vehicles, self-navigating robotics and drones in industrial applications, and 3D capture of objects coupled with 3D imaging or printing. In the Industrial end-market, our diode lasers are used primarily as pump sources for pulsed and kilowatt class fiber lasers.

Lasers

Our Lasers products serve our customers in markets and applications such as sheet metal processing, general manufacturing, biotechnology, graphics and imaging, remote sensing, and precision machining such as drilling in printed circuit boards, wafer singulation, glass cutting and solar cell scribing.

Our Lasers products are used in a variety of OEM applications including diode-pumped solid-state, fiber, diode, direct-diode and gas lasers such as argon-ion and helium-neon lasers. Fiber lasers provide kW-class output powers combined with excellent beam quality and are used in sheet metal processing and metal welding applications. Diode-pumped solid-state lasers provide excellent beam quality, low noise and exceptional reliability and are used in biotechnology, graphics and imaging, remote sensing, materials processing and precision machining applications. Diode and direct-diode lasers address a wide variety of applications, including laser pumping, thermal exposure, illumination, ophthalmology, image recording, printing, plastic welding and selective soldering. Gas lasers such as argon-ion and helium-neon lasers provide a stable, low-cost and reliable solution over a wide range of operating conditions, making them well-suited for complex, high-resolution OEM applications such as flow cytometry, DNA sequencing, graphics and imaging and semiconductor inspection.

We also provide high-powered and ultrafast lasers for the industrial and scientific markets. Manufacturers use high-power, ultrafast lasers to create micro parts for consumer electronics and to process semiconductor, LED, and other types of chips. Use of ultrafast lasers for micromachining applications is being driven primarily by the increasing use of consumer electronics and connected devices globally.

We do not allocate research and development, sales and marketing, or general and administrative expenses to our segments because management does not include the information in its measurement of the performance of the operating segments. In addition, we do not allocate amortization and impairment of acquisition-related intangible assets, stock-based compensation and certain other charges impacting the gross margin of each segment because management does not include this information in its measurement of the performance of the operating segments.

Information on reportable segments utilized by our CODM is as follows (in millions):

Our excess and obsolete inventory charges related to Huawei were offset by $2.1 million of sale of inventory previously written down during the three and nine months ended April 3, 2021. During the nine months ended April 3, 2021, there was also a $5.0 million impairment charge associated with excess capacity related to our Fiber laser business.

“Other charges” of unallocated corporate items for the three and nine months ended March 28, 2020 primarily include costs of transferring product lines to new production facilities, including Thailand of $0.4 million and $8.5 million, respectively. We also incurred excess and obsolete inventory charges driven by the decline in demand from Huawei of $0.1 million and $12.8 million during the three and nine months ended March 28, 2020. In addition, there were expenses of $1.6 million related to the COVID-19 outbreak during the three and nine months ended March 28, 2020.

Disaggregation of Revenue

We disaggregate revenue by product and by geography. We do not present other levels of disaggregation, such as by type of products, customer, markets, contracts, duration of contracts, timing of transfer of control and sales channels, as this information is not used by our CODM to manage the business.

The table below discloses our total net revenue attributable to each of our two reportable segments. In addition, the table sets forth the percentage of our total net revenue attributable to our product offerings which serve Telecom and Datacom, and Consumer and Industrial markets which accounted for 10% or more of our total net revenue during the periods presented (in millions, except percentage data):

Description of Business and Summary of Significant Accounting Policies (Policies)

9 Months Ended

Apr. 03, 2021

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The preparation of the condensed consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results may be different from the estimates. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are inventory valuation, revenue recognition, income taxes, and goodwill.

The COVID-19 pandemic has created and may continue to create significant uncertainty in global financial markets, which has disrupted and harmed, and may continue to disrupt and harm, the Company's business, financial condition, and results of operations. The extent of the impact of COVID-19 on the Company's operational and financial performance will depend on certain developments, including but not limited to the duration and spread of the outbreak, duration of local, state and federal issued public health orders in each jurisdiction where we operate or in which our customers and suppliers operate, impact on our customers and our sales cycles, impact on our supply chain and manufacturing partners, impact on our employees and impact on regional and worldwide economies and financial markets in general, all of which are uncertain and cannot be predicted.

Fiscal Years

Fiscal Years

We utilize a 52-53 week fiscal year ending on the Saturday closest to June 30th. Every fifth or sixth fiscal year will have a 53-week period. The additional week in a 53-week year is added to the third quarter, making such quarter consist of 14 weeks. Our fiscal 2021 is a 53-week year ending on July 3, 2021, with the quarter ended April 3, 2021 being a 14-week quarterly period. Our fiscal 2020 was a 52-week year that ended on June 27, 2020, with the quarter ended March 28, 2020 being a 13-week quarterly period.

Principles of Consolidation

Principles of ConsolidationThese interim unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

Accounting Policies, Accounting Pronouncements Recently Adopted and Accounting Pronouncements Not Yet Effective

Accounting PoliciesThe accompanying condensed consolidated financial statements and accompanying related notes should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended June 27, 2020.

Accounting Pronouncements Recently Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on transfers between Level 1 and Level 2, valuation processes of Level 3 fair value measurements, and the categorization by level for items that are not measured at fair value, but for which the fair value is required to be disclosed. We adopted ASU 2018-13 in the first quarter of fiscal 2021 with no impact to our condensed consolidated financial statements.

In August 2018, FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This standard requires capitalization of the implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Further, the standard also requires the Company to expense the capitalized implementation costs of a hosting arrangement over the term of the hosting arrangement. We adopted ASU 2018-15 in the first quarter of fiscal 2021 with no impact to our condensed consolidated financial statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and a subsequent amendment, ASU 2018-19 (collectively, Topic 326). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. We adopted ASU 2016-13 using the modified-retrospective approach in the first quarter of fiscal 2021 with no material impact to our condensed consolidated financial statements.

With the adoption of Topic 326, we are now assessing whether unrealized losses have resulted from a credit loss or other factors. We believe none of our unrealized losses on available-for-sale investments were other-than temporary or were attributable to credit losses as of April 3, 2021 and June 27, 2020. We review our available-for-sale investments on a quarterly basis to identify a potential other-than-temporary impairment. The investments with unrealized losses consisted primarily of corporate debt securities, and given the extent of the unrealized loss positions, the issuers' high credit ratings and the near-term market conditions, we believe our unrealized losses are temporary. We also do not have an intent to sell our investments and would not be required to sell them before they recover.

The adoption of Topic 326 did not significantly change our approach to the valuation of trade receivables. We determine whether there is an expected loss on our accounts receivable by reviewing all available data, including our customers' latest available financial statements, their credit standing and historical collection experience, as well as current and future market and economic conditions. As of April 3, 2021 and June 27, 2020, the allowance for credit losses on our trade receivables was $1.8 million and $1.8 million, respectively.

Accounting Pronouncements Not Yet Effective

In August 2020, FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for convertible instruments by removing the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. As a result, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost. Also, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and the treasury stock method will be no longer available. The new guidance is effective for fiscal years beginning after December 15, 2021, with early adoption permitted no earlier than fiscal years beginning after December 15, 2020. ASU 2020-06 is effective for us in our first quarter of fiscal year 2023. We are currently evaluating the impact of ASU 2020-06 on our condensed consolidated financial statements.

In December 2019, FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), which is intended to simplify various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and which also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for us at the beginning of fiscal year 2022, including interim periods within that reporting period, although early adoption is permitted. We are currently evaluating the impact of ASU 2019-12 on our condensed consolidated financial statements. In August 2018, FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Topic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies the disclosure requirements for defined benefit pension plans and other post-retirement benefit plans. The new guidance is effective for fiscal years ending after December 15, 2020, with early adoption permitted. ASU 2018-14 should be applied retrospectively to all periods presented and is effective for us in our fourth quarter of fiscal year 2021 as ASU 2018-14 does not amend the interim disclosure requirements.

Fair Value Measurements

We determine fair value based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value:

Level 1:	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2:	Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.
Level 3:	Inputs are unobservable inputs based on our assumptions.

The fair value of our Level 1 financial instruments, such as money market funds and U.S. Treasury securities, which are traded in active markets, is based on quoted market prices for identical instruments. The fair value of our Level 2 fixed income securities is obtained from an independent pricing service, which may use quoted market prices for identical or comparable instruments or model driven valuations using observable market data or inputs corroborated by observable market data. Our marketable securities are held by custodians who obtain investment prices from a third-party pricing provider that incorporates standard inputs in various asset price models. Our procedures include controls to ensure that appropriate fair values are recorded, including comparing the fair values obtained from our pricing service against fair values obtained from another independent source.

Assets Measured at Fair Value on a Non-Recurring Basis

We periodically review our intangible and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and its eventual disposition. If not recoverable, an impairment loss would be calculated based on the excess of the carrying amount over the fair value.

Management utilizes various valuation methods, including an income approach, a market approach and a cost approach, to estimate the fair value of intangibles and other long-lived assets.

(1) In fiscal 2019, as a result of significant changes in economic facts and circumstances, primarily due to the acquisition of Oclaro, we established the functional currency for our worldwide operations as the U.S. dollar. Translation adjustments reported prior to December 10, 2018, remain as a component of accumulated other comprehensive income in our condensed consolidated balance sheets, until all or a part of the investment in the subsidiaries is sold or liquidated.

(2) We evaluate the assumptions over the fair value of our defined benefit obligations annually and make changes as necessary.(3) Unrealized loss on available-for-sale securities for the three and nine months ended April 3, 2021 is presented net of tax of $0.1 million and $0.6 million, respectively. Tax impact was not material for the other periods presented.
