Overview

We are an industry-leading provider of optical and photonic products defined by revenue and market share, essential to range of cloud, artificial intelligence and machine learning (“AI/ML”), telecommunications, consumer, and industrial end-market applications.

We have two operating segments, Cloud & Networking and Industrial Tech. 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 will 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. The advent of AI/ML has caused a dramatic surge in the growing demands on data networking in cloud data centers and accelerated the usage of optical components and modules. We expect that the accelerating shift to digital and virtual approaches to many aspects of work and life 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 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 for security, industrial and automotive applications are rapidly developing markets. 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. 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, both organically and through acquisitions, 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.

Cloud & Networking

Our Cloud & Networking products include comprehensive portfolio of optical and photonic chips, components, modules, and subsystems supplied to cloud data center operator, AI/ML infrastructure provider, and network equipment manufacturer customers who are building cloud data center and network infrastructures. Our products enable high-capacity optical links in cloud, AI/ML and DCI applications, and communications service provider networks, including products for access (local), metro (intracity), long-haul (city-to-city and worldwide) and submarine (undersea) network infrastructure. Our Cloud & Networking products also support network equipment manufacturers building enterprise network infrastructure, including SANs, LANs, and WANs. Demand for our Cloud & Networking products is driven by the continual growth in network capacity required for cloud computing and services, including for AI/ML, streaming video and video conferencing, wireless and mobile services, and IoT.

Industrial Tech

Our Industrial Tech products include short pulse solid-state lasers, kilowatt-class fiber lasers, diode lasers, and gas lasers, which address applications in numerous end-markets. In the consumer end-market, our laser light sources are integrated into our customers’ 3D sensing cameras, which are used in mobile devices, payment kiosks, and other consumer electronics devices to enable applications including biometric identification, computational photography and virtual and augmented reality. In the automotive end-market, our lasers are used in our customers’ LiDAR and other optical sensor devices, which are increasingly being used in advanced driver assistance systems (“ADAS”) and in-cabin driver and occupant monitoring systems. In the industrial manufacturing end-market, our lasers are incorporated into our customers’ manufacturing machine tools used for the precision processing of materials in a range of industries including semiconductor device and microelectronics fabrication, electric vehicle and battery production, metal cutting and welding, and advanced manufacturing. Our products can also be used in the industrial end-market in imaging and sensing systems for process feedback and control, quality assurance, and waste

reduction. Adoption of our products in the industrial end-market is driven by the needs of customers to advance semiconductor and microelectronics industry roadmaps, and by Industry 4.0/5.0 trends, including increasing manufacturing precision and flexibility and reducing waste and environmental impact. Demand for our products in the industrial end-market is driven by end-customer investments in manufacturing capacity. Our lasers also address certain semiconductor inspection and life-science applications.

Acquisition of Cloud Light

On November 7, 2023 (the “Cloud Light Closing Date”), we completed the acquisition of Cloud Light. Cloud Light designs, markets, and manufactures advanced optical modules for data center interconnect applications. The acquisition enables us to be well-positioned to serve the growing needs of cloud & networking customers, particularly those focused on optimizing their data center infrastructure for the demands of AI/ML. On the Cloud Light Closing Date, we paid $705.0 million of total cash consideration to Cloud Light. Additionally, each of Cloud Light’s outstanding options was exchanged for a combination of cash and options to acquire Lumentum common stock having equivalent value (the “replacement options”). These replacement options have a total fair value of $38.9 million as of the Cloud Light Closing Date, of which $23.5 million attributed to pre-acquisition service is recorded as part of purchase price consideration and the remaining $15.4 million is recorded as post-acquisition stock-based compensation expense over the vesting period of three years from the Cloud Light Closing Date. We incurred a total of $9.6 million of acquisition-related costs, representing professional and other direct acquisition costs, which was recorded as general and administrative expense in the consolidated statement of operations for the year ended June 29, 2024. Refer to “Note 4. Business Combinations” in the notes to condensed consolidated financial statements.

We evaluate strategic opportunities regularly and, where appropriate, may acquire additional businesses, products, or technologies that are complementary to, or broaden the markets for our products. We believe we have strengthened our business model by expanding our addressable markets, customer base and expertise, diversifying our product portfolio and fortifying our core businesses from acquisitions as well as through organic initiatives.

Supply Chain and Inventory Management

Our business and our customers’ businesses were negatively impacted by worldwide logistics and supply chain issues during the COVID-19 pandemic, including constraints on available cargo capabilities and limited availability of once broadly available supplies of both raw materials and finished components. COVID-19 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. Although the supply chain constraints started to improve in the latter half of fiscal 2023, we felt its ongoing effects in fiscal 2024, as described below, and these constraints or effects may impact our ability to supply our products to our customers and may reduce our revenue and profit margin if they reoccur. In addition, if our customers are unable to procure needed semiconductor components, their demand for our products will decrease. Due to the global supply chain constraints, we have had to incur incremental supply and procurement costs in order to increase our ability to fulfill demands from our customers.

In addition, in response to component shortages, certain of our customers accumulated inventory that they began managing down in fiscal year 2024 as supply conditions improved. Customers who had built up large inventories when supply chains were tight brought down inventories as supply chain constraints eased and in some cases these customers delayed projected shipments, which caused our revenue to decline and our margins have been adversely impacted as we have not able to fully recover costs, such as underutilized manufacturing capacity. However, we have recently seen signs of inventory normalization at network equipment manufacturers since the first fiscal quarter of 2025 and have seen continued improvement in the second fiscal quarter of 2025.

For more information on risks associated with supply chain constraints and customer inventory management, see the section titled “Risk Factors” in Item 1A of Part II of this report.

Critical Accounting Policies and Estimates

Our condensed and 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”). We also 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

• Business Combinations

• Goodwill and Intangible Assets - Impairment Assessment

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 29, 2024 provides a complete discussion of our critical accounting policies and estimates. There have been no changes to these policies during the three and six months ended December 28, 2024.

Net Revenue

Net revenue increased by $35.4 million, or 9.7%, during the three months ended December 28, 2024 compared to the three months ended December 30, 2023, driven by a $52.5 million increase in Cloud & Networking revenue offset by a $17.1 million decrease in Industrial Tech revenue. The increase in Cloud & Networking net revenue is primarily due to higher revenue from cloud and AI/ML customers, which increased by $34.5 million. In addition, we recognized an increase in revenue of $30.1 million from network equipment manufacturers due to the start of market recovery and the related inventory normalization. This was partially offset by a reduction in shipments to a specific customer in China driven by U.S. trade restrictions. The decrease in Industrial Tech net revenue is primarily due to higher market competition in the consumer end-market for our imaging and sensing products.

Net revenue increased by $54.7 million, or 8.0%, during the six months ended December 28, 2024 compared to the six months ended December 30, 2023, driven by a $105.1 million increase in Cloud & Networking revenue offset by a $50.4 million decrease in Industrial Tech revenue. The increase in Cloud & Networking net revenue is primarily due to higher revenue from cloud and AI/ML customers, which increased by $111.0 million, inclusive of revenue from Cloud Light, which we acquired in the second quarter of fiscal 2024. In addition, we recognized an increase in revenue of $38.0 million from network equipment manufacturers due to the start of market recovery and the related inventory normalization. This was partially offset by a reduction in shipments to a specific customer in China driven by U.S. trade restrictions. The decrease in Industrial Tech net revenue is primarily due to higher market competition in the consumer end-market for our imaging and sensing products.

During the three months ended December 28, 2024, three customers individually accounted for 16%, 14% and 11% of our total revenue, respectively. During the six months ended December 28, 2024, three customers individually accounted for 15%, 13% and 10% of our total net revenue, respectively. We had no other customers that represented 10% or greater of our total net revenue.

During the three months ended December 30, 2023, three customers individually accounted for 19%, 13% and 11% of our total revenue, respectively. During the six months ended December 30, 2023, three customers individually accounted for 14%, 12% and 12% of our total net revenue, respectively. We had no other customers that represented 10% or greater of our total net revenue.

Revenue by Region

We operate in three geographic regions: Americas, Asia-Pacific, and EMEA (Europe, Middle East, and Africa). 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, which may differ from the location of their end customers.

The following table presents net revenue by the three geographic regions we operate in and net revenue from countries that generally represented 10% or more of our total net revenue (in millions, except percentage data):

			Three Months Ended																								Six Months Ended

For the three and six months ended December 28, 2024, net revenue from customers outside the United States, based on customer shipping location, represented 80.7% and 80.7% of net revenue, respectively.

For the three and six months ended December 30, 2023, net revenue from customers outside the United States, based on customer shipping location, represented 71.9% and 79.0% of net revenue, respectively.

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

Gross margin for the three months ended December 28, 2024 increased to 24.8% from 17.4% for the three months ended December 30, 2023. The increase was driven by a $10.8 million reduction in excess and obsolete inventory charges during the three months ended December 28, 2024 primarily driven by the U.S. trade restrictions imposed during the three months ended December 30, 2023 whereby we were no longer able to sell certain products to one of our customers. In addition, costs incurred during the three months ended December 28, 2024 related to the acquisition of Cloud Light, including integration costs and amortization of inventory fair value adjustments decreased by $10.6 million compared to the prior period. Within our segments, our Cloud & Networking segment gross margin increased during the three months ended December 28, 2024 due to higher revenue and better factory utilization driven by increased production of products for sale to network equipment manufacturer

customers, which positively impacted gross margin by approximately 1.5%. Industrial Tech segment gross margin decreased during the three months ended December 28, 2024 primarily due to lower sales of imaging and sensing products into consumer electronic customers, which negatively impacted our gross margin by approximately 1%.

Gross margin for the six months ended December 28, 2024 increased to 24.0% from 20.6% for the six months ended December 30, 2023. The increase was driven by a $19.2 million reduction in excess and obsolete inventory charges during the six months ended December 28, 2024 primarily driven by the U.S. trade restrictions imposed during the three months ended December 30, 2023 whereby we were no longer able to sell certain products to one of our customers. In addition, costs incurred during the six months ended December 28, 2024 related to the acquisition of Cloud Light, including integration costs and amortization of inventory fair value adjustments were $12.7 million lower compared to the prior year period. Our Cloud & Networking segment gross margin was approximately flat. Industrial Tech segment gross margin decrease during the six months ended December 28, 2024 primarily due to lower sales of imaging and sensing products to consumer electronics customers, which negatively impacted our gross margin by approximately 1%.

The markets in which we sell products are 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 variants in buying patterns. We expect these factors to result in variability of our gross margin and our gross margin maybe subject to increasing downward pressure due to these factors.

Segment Profit (Loss)

The following table summarizes segment profit (loss) for each of our operating segments for the periods presented (in millions):

			Three Months Ended												Six Months Ended
			December 28, 2024						December 30, 2023						December 28, 2024						December 30, 2023
Cloud & Networking			$	54.9					29.1						$	91.4					$	53.0
Industrial Tech			3.9						12.7						6.1						28.0

Cloud & Networking segment profit increased by $25.8 million, or 88.7%, during the three months ended December 28, 2024 as compared to the three months ended December 30, 2023 primarily due to higher sales of our products to both cloud and AI/ML customers and to network equipment manufacturer customers. Industrial Tech segment profit decreased by $8.8 million, or 69.3%, during the three months ended December 28, 2024 as compared to the three months ended December 30, 2023 primarily due to lower revenue, mainly from sales of imaging and sensing products to consumer electronics customers.

Cloud & Networking segment profit increased by $38.4 million, or 72.5%, during the six months ended December 28, 2024 as compared to the six months ended December 30, 2023 primarily due to higher sales of our products to both cloud and AI/ML customers. Industrial Tech segment profit decreased by $21.9 million, or 78.2%, during the six months ended December 28, 2024 as compared to the six months ended December 30, 2023 primarily due to lower revenue, mainly from sales of imaging and sensing products.

Research and Development (“R&D”)

R&D expense decreased by $4.1 million, or 5.2% for the three months ended December 28, 2024 compared to the three months ended December 30, 2023, primarily due to $2.2 million of lower spending in software and computer supplies used for R&D purposes and lower payroll and other compensation related expenses due to lower headcount as a result of restructuring actions primarily due to the discontinuation of our in-house development of coherent DSPs and RFICs. This was partially offset by $1.7 million of higher depreciation expense.

R&D expense decreased by $3.3 million, or 2.2% for the six months ended December 28, 2024 compared to the six months ended December 30, 2023. The decrease in R&D expense for the six months ended December 30, 2023 was primarily driven by lower payroll and other compensation related expenses due to lower headcount as a result of restructuring actions primarily due to the discontinuation of our in-house development of coherent DSPs and RFICs. This was partially offset by $2.5 million of higher spending in software and computer supplies used for R&D purposes and lower funding from customers and $2.2 million of higher depreciation expense.

We believe that continuing our investments in R&D is critical to attaining our strategic objectives. We plan to continue to invest in R&D and new products that we believe will further differentiate us in the marketplace.

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

SG&A expense decreased by $8.8 million, or 10.3%, during the three months ended December 28, 2024 compared to the three months ended December 30, 2023. The decrease was driven by $9.2 million of lower acquisition costs and outside consultant costs as a result of business and system integrations efforts as well as a reduction in payroll related expenses as a result of restructuring actions in the prior periods. This was partially offset by a $2.6 million increase in stock-based compensation expense and $1.4 million of incremental amortization of intangible assets associated with the Cloud Light acquisition.

SG&A expense decreased by $5.5 million, or 3.5%, during the six months ended December 28, 2024 compared to the six months ended December 30, 2023. The decrease was primarily driven by $12.6 million of lower acquisition costs related to Cloud Light, which we acquired in second quarter of fiscal year 2024, as well as a reduction in payroll related expenses as a result of restructuring actions in the prior periods. This was partially offset by $9.6 million of incremental amortization of intangible assets associated with the Cloud Light acquisition and a $3.4 million increase in stock-based compensation expense.

From time-to-time, we incur expenses that are not part of our ordinary operations, such as mergers and acquisition-related and litigation expenses, which generally increase our SG&A expenses and potentially impact our profitability expectations in any particular period.

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 and as a result of recent acquisitions.

During the three and six months ended December 28, 2024, we recorded restructuring and related charges of $0.7 million and $10.4 million, respectively mainly due to our integration efforts and cost reduction initiatives. Restructuring charges for the six months ended December 28, 2024 includes $6.2 million of asset write-offs primarily due to integration efforts to consolidate our sites, $3.0 million of charges related to the discontinuation of our in-house development of coherent DSPs and RFICs and the remaining restructuring charges due to company-wide cost reduction initiatives.

During the three and six months ended December 30, 2023, we recorded restructuring and related charges of $5.8 million and $16.8 million, respectively, primarily due to company-wide cost reduction initiatives, as well as our integration efforts as a result of the NeoPhotonics acquisition in August 2022.

Interest Expense

For the three months ended December 28, 2024 and December 30, 2023, we recorded interest expense of $5.6 million and $9.7 million, respectively. For the six months ended December 28, 2024 and December 30, 2023, we recorded interest expense of $11.1 million and $19.4 million, respectively. Interest expense is primarily driven by the amortization of the debt discount and issuance costs of our convertible notes. The decrease in interest expense for the three and six months ended December 28, 2024 is mainly due to the repayment of our 2024 Notes (as defined below) upon maturity in March 2024.

Other Income, Net

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

			Three Months Ended												Six Months Ended
			December 28, 2024						December 30, 2023						December 28, 2024						December 30, 2023
Foreign exchange and other gains (losses), net			$	5.9					$	(3.7)					$	5.2					$	(4.2)
Interest and investment income, net			9.0						17.1						18.4						38.8
Total other income, net			$	14.9					$	13.4					$	23.6					$	34.6

Other income, net for the three months ended December 28, 2024 increased by $1.5 million compared to the three months ended December 30, 2023 due to the decrease of foreign exchange losses of $9.6 million mainly driven by the Japan term loans denominated in Japanese Yen, which weakened relative to the U.S. dollar during the three months ended December 28, 2024 partially offset by a decrease of $8.1 million in interest and investment income driven by lower short term investment balances, as we used cash to purchase Cloud Light as well as the repayment of the 2024 Notes in March 2024.

Other income, net for the six months ended December 28, 2024 decreased by $11.0 million from the six months ended December 30, 2023 due to $20.4 million of decrease in interest and investment income driven by lower short term investment balances, as we used cash to purchase Cloud Light as well as the repayment of the 2024 Notes in March 2024, offset by a decrease in foreign exchange losses of $9.4 million mainly driven by the Japan term loans denominated in Japanese Yen, which weakened relative to the U.S. dollar during the six months ended December 30, 2023.

Provision (Benefit) for Income Taxes

The following table summarizes provision (benefit) for income taxes for the periods presented (in millions):

			Three Months Ended												Six Months Ended
			December 28, 2024						December 30, 2023						December 28, 2024						December 30, 2023
Income tax provision (benefit)			$	18.6					$	(2.4)					$	21.8					$	(3.8)

We recorded a tax provision of $18.6 million and $21.8 million for the three and six months ended December 28, 2024, respectively. Our tax provision for the three months ended December 28, 2024 is primarily attributable to the income tax expense from pre-tax earnings, interest on uncertain tax positions and withholding taxes, partially offset by the tax benefit from prior year changes in uncertain tax positions. Our tax provision for the six months ended December 28, 2024 is primarily attributable to the income tax expense from pre-tax earnings, interest on uncertain tax positions, foreign return to provision differences and withholding taxes, partially offset by the tax benefit from prior year changes in uncertain tax positions.

We recorded a tax benefit of $2.4 million and $3.8 million for the three and six months ended December 30, 2023, respectively. Our tax benefit for the three months ended December 30, 2023 includes a discrete tax expense of $3.4 million, primarily related to a shortfall in connection with stock-based compensation vested during the quarter, interest on uncertain tax positions and currency re-measurements. Our tax benefit for the six months ended December 30, 2023 includes a discrete tax expense of $1.6 million, primarily related to a shortfall in connection with stock-based compensation vested during the quarter, foreign return to provision differences and interest on unrecognized tax positions, partially offset by the tax benefit from changes in prior year uncertain tax positions.

Our estimated effective tax rate for the three months ended December 28, 2024 differs from the 21% U.S. statutory rate primarily due to the income tax expense from foreign rate differential, non-deductible stock-based compensation, and current year valuation allowance changes, partially offset by the income tax benefit from various income tax credits.

We regularly assess our ability to realize our deferred tax assets on a quarterly basis and will establish a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized. As of December 28, 2024, we maintain a full valuation allowance on U.S. federal and state and certain foreign deferred tax assets. We will continue to assess the need for a valuation allowance against our remaining deferred tax assets and may increase or decrease our valuation allowance materially in the future.

Our provision for incomes taxes may be impacted by changes in the geographic mix of earnings, acquisitions, changes in the realizability of deferred tax assets, changes in our uncertain tax positions, the results of income tax audits, settlements with tax authorities, the expiration of statutes of limitations, the implementation of tax planning strategies, tax rulings, court decisions, and changes in tax laws and regulations. It is also possible that significant negative or positive evidence may become available that causes us to change our conclusion regarding whether a valuation allowance is needed on certain of our deferred tax assets, which would affect our income tax provision in the period of such change.

We also evaluate changes to regulations and requirements in the international jurisdictions where we conduct our business. For additional information, refer to Part II Item 1A “Risk Factors”.

Financial Condition

Liquidity and Capital Resources

As of December 28, 2024 and June 29, 2024, our cash and cash equivalents were $479.7 million and $436.7 million, respectively. As of December 28, 2024 and June 29, 2024, our short-term investments of $417.0 million and $450.3 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 provide for diversification of investments and is focused on the preservation of capital and supporting our liquidity requirements.

The total amount of cash held by the non-United States entities as of December 28, 2024 and June 29, 2024 was $343.9 million and $306.9 million, respectively, which was primarily held by entities incorporated in the United Kingdom, the British Virgin Islands, Japan, Hong Kong, China, Switzerland, the Cayman Islands, Thailand and Brazil. Although cash currently held in the United States, as well as 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, strategic transactions and partnerships, and future acquisitions.

Our intent is to indefinitely reinvest funds held outside the United States. Except for the funds held in the Cayman Islands, the British Virgin Islands, and Hong Kong, as well as certain subsidiaries in China and Japan, 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 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, it may create dilution to our existing stockholders. However, any such financing may not be available on terms favorable to us or may not be available at all.

Liquidity and Capital Resources Requirements

We believe that our cash and cash equivalents as of December 28, 2024 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.

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 uncertainty in the banking and financial services industries;

• 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, including increases in manufacturing capacity;

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

• timing of payments to our suppliers;

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

• cost and availability of credit, which may impact available financing for us, our customers or others with whom we do business;

• 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;

• acquisitions or strategic transactions, in particular the Cloud Light acquisition;

• the settlement of any conversion or redemption of our convertible notes in cash;

• the timing of settlement or other resolution of legal contingencies; and

• common stock repurchases under the share buyback program.

Contractual Obligations

The following table summarizes our contractual obligations as of December 28, 2024, and the effect such obligations are expected to have on our liquidity and cash flow (in millions):

			Payments Due
			Total						Less Than 1 Year						More Than 1 Year
Contractual Obligations
Asset retirement obligations			$	7.0					$	—					$	7.0
Operating lease liabilities, including imputed interest (1)			40.2						12.7						27.5
Pension plan contributions (2)			1.6						1.6						—
Purchase obligations (3)			620.1						578.1						42.0
Term loans - principal (5)			66.3						9.8						56.5
Term loans - interest (5)			1.9						0.6						1.3
Convertible notes - principal (4)			2,514.7						—						2,514.7
Convertible notes - interest (4)			70.9						18.7						52.2
Total			$	3,322.7					$	621.5					$	2,701.2

(1) The amounts of operating lease liabilities do not include any sublease income amounts nor do they include payments for short-term leases or variable lease payments. As of December 28, 2024, we expect to receive sublease income of approximately $2.6 million over the sublease periods.

(2) The amount of pension plan contributions 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) The amounts related to convertible notes include principal and interest on our 0.50% Convertible Senior Notes due 2026 (the “2026 Notes”), principal and interest on our 0.50% Convertible Senior Notes due 2028 (the “2028 Notes”), and principal and interest on our 1.50% Convertible Senior Notes due 2029 (the “2029 Notes”). The 2026 Notes have a maturity date of December 15, 2026, the 2028 Notes have a maturity date of June 15, 2028, and the 2029 Notes have a maturity date of December 15, 2029. The principal balances of our convertible notes are reflected in the payment periods in the table above based on their respective contractual maturities assuming no conversions.

(5) The amounts related to term loans include principal and interest on our Sumitomo Mitsui Banking Corporation (“SMBC”) term loan with a fixed annual interest rate of 0.88% and Mizuho Bank, Ltd. (“Mizuho”) term loan with a fixed annual interest rate of 0.90%. The SMBC term loan requires monthly principal payments with the remaining principal due on the loan maturity date of July 31, 2029 while the Mizuho term loan requires quarterly principal payments with the final payment date on September 20, 2029.

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

Indebtedness

As of December 28, 2024, the net carrying amount of our 2029 Notes of $599.9 million (principal balance of $603.7 million maturing in 2029) is presented in non-current liabilities. If the closing price of our stock exceeds $90.40 (or 130% of the conversion price of $69.54) for 20 of the last 30 trading days of any future quarter, our 2029 Notes would become convertible at the option of the holders during the subsequent fiscal quarter and the debt would be reclassified to current liabilities in our consolidated balance sheets.

As of December 28, 2024, the net carrying amount of our 2028 Notes of $857.1 million (which have an aggregate principal amount of $861.0 million outstanding that matures in 2028) is presented in non-current liabilities in our condensed consolidated balance sheets. If the closing price of our stock exceeds $170.34 (or 130% of the conversion price of $131.03) for 20 of the last 30 trading days of any future fiscal quarter, our 2028 Notes would become convertible at the option of the holders during the subsequent fiscal quarter and the debt would be reclassified to current liabilities in our condensed consolidated balance sheet.

As of December 28, 2024, the net carrying amount of our 2026 Notes of $1,047.7 million (which have an aggregate principal amount of $1,050.0 million outstanding that matures in 2026) is presented in non-current liabilities in our condensed consolidated balance sheets. 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 fiscal quarter, our 2026 Notes would become convertible at the option of the holders during the subsequent fiscal quarter and the debt would be reclassified to current liabilities in our condensed consolidated balance sheet.

As of December 28, 2024, the Company has $39.2 million in principal amount outstanding on our SMBC term loan, of which the short-term portion of $4.1 million is recorded as current liabilities while the long-term portion of $35.1 million is recorded as long-term debt in the Company’s condensed consolidated balance sheets.

As of December 28, 2024, the Company has $27.1 million in principal amount outstanding on our Mizuho term loan, of which the short-term portion of $5.7 million is recorded as current liabilities while the long-term portion of $21.4 million is recorded as long-term debt in the Company’s condensed consolidated balance sheets.

Share Buyback Program

We have a share buyback program that authorizes us to utilize up to an aggregate amount of $1.2 billion to purchase our own shares of common stock through May 2025. During the six months ended December 28, 2024, we did not repurchase any shares of our common stock. Since the board of directors initially approved the share buyback program, we have repurchased 7.7 million shares in aggregate at an average price of $81.66 per share for a total purchase price of $630.4 million. We recorded the $630.4 million aggregate purchase price as a reduction of retained earnings within our condensed consolidated balance sheet. All repurchased shares were retired immediately. As of December 28, 2024, we have $569.6 million remaining under the share buyback program.

The price, timing, amount, and method of future 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 the Company and our stockholders. The stock repurchase program may be suspended or terminated at any time.

Unrecognized Tax Benefits

As of December 28, 2024 and June 29, 2024, our other non-current liabilities include unrecognized tax benefit for uncertain tax positions of $95.5 million and $83.0 million, respectively. We are unable to reliably estimate the timing of future payments related to uncertain tax positions.

Cash Flows

Our balance of cash and cash equivalents increased by $43.0 million from $436.7 million as of June 29, 2024 to $479.7 million as of December 28, 2024. The increase in cash and cash equivalents during the six months ended December 28, 2024 was due to cash from operating activities of $63.9 million and cash from financing activities of $56.9 million, offset by cash used in investing activities of $77.8 million.

Operating Cash Flow

Cash from operating activities was $63.9 million during the six months ended December 28, 2024, which reflects a net loss of $143.3 million, offset by non-cash items of $209.1 million and changes in operating assets and liabilities of $1.9 million. Changes in operating assets and liabilities were primarily driven by an increase in accounts payable of $38.7 million primarily due to higher inventory purchases and capital expenditures and an increase in income tax liabilities of $28.5 million primarily due to income tax provision for the six months ended December 28, 2024, offset by an increase of $15.0 million in prepayments and other current and non-current assets related mainly to value-added-tax receivables driven by higher recent capital expenditures and inventory purchases, and a decrease of $19.9 million in accrued expenses and other current and non-current liabilities primarily due to payment of the net settlement amount of the Oclaro merger litigation.

Cash used in operating activities was $3.8 million during the six months ended December 30, 2023, which reflects a net loss of $167.0 million and non-cash items of $194.7 million, offset by $31.5 million of changes in our operating assets and liabilities. Changes in our operating assets and liabilities were primarily driven by a decrease in accounts payable of $51.1 million primarily due to lower purchases from our contract manufactures and linearity of payments, and a decrease in income taxes of $26.6 million primarily due annual income tax payable in Japan, offset by a decrease in accounts receivable of $18.7 million due to lower revenue and a decrease in inventories of $7.5 million primarily due to reduced inventory level in our Cloud & Networking business.

Investing Cash Flow

Cash used in investing activities of $77.8 million during the six months ended December 28, 2024 was attributable to capital expenditures of $114.3 million, offset by net proceeds from sales or maturities of short-term investments of $36.3 million and proceeds from sales of property and equipment of $0.2 million.

Cash used in investing activities of $377.1 million during the six months ended December 30, 2023 was attributable to cash used in the acquisition of Cloud Light of $700.9 million, net of cash acquired, capital expenditures of $88.8 million, and an intangible asset acquisition of $3.0 million, offset by net proceeds from sales or maturities of short-term investments of $415.4 million and proceeds from sales of property and equipment of $0.2 million.

Financing Cash Flow

Cash from financing activities of $56.9 million during the six months ended December 28, 2024 was attributable to $76.5 million of proceeds from SMBC and Mizuho term loans and $8.1 million of proceeds from employee stock plans, offset by tax payments related to net share settlement of restricted stock of $23.8 million, payment for an intangible asset acquisition holdback of $1.0 million and $2.9 million of principal payments on term loans.

Cash used in financing activities of $8.8 million during the six months ended December 30, 2023 was attributable to tax payments related to net share settlement of restricted stock of $16.1 million, offset by $7.3 million of proceeds from employee stock plans.
