NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization and Basis of Presentation
Western Digital Corporation (“Western Digital” or the “Company”) is a leading developer, manufacturer, and provider of data storage devices and solutions based on both NAND flash and hard disk drive technologies.
The Company’s broad portfolio of technology and products address the following key end markets: Cloud, Client and Consumer. The Company also generates immaterial license and royalty revenue from its extensive intellectual property portfolio, which is included in each of these three end market categories.
The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Basis of Presentation, of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the year ended June 30, 2023. In the opinion of management, all adjustments necessary to fairly state the Condensed Consolidated Financial Statements have been made. All such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in the Consolidated Financial Statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10‑K for the year ended June 30, 2023. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year.
Fiscal Year
The Company’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, the Company reports a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2024, which will end on June 28, 2024, and fiscal year 2023, which ended June 30, 2023, are each comprised of 52 weeks, with all quarters presented consisting of 13 weeks.
Segment Reporting
The Company manufactures, markets, and sells data storage devices and solutions in the United States (“U.S.”) and in foreign countries through its sales personnel, dealers, distributors, retailers, and subsidiaries. The Company manages and reports under two reportable segments: flash-based products (“Flash”) and hard disk drives (“HDD”).
The Chief Executive Officer, who is the Company’s Chief Operating Decision Maker (“CODM”), evaluates the performance of the Company and makes decisions regarding the allocation of resources based on each operating segment’s net revenue and gross margin. Because of the integrated nature of the Company’s production and distribution activities, separate segment asset measures are either not available or not used as a basis for the CODM to evaluate the performance of or to allocate resources to the segments.
Use of Estimates
Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented with consideration given to the potential impacts of current macroeconomic conditions. However, actual results could differ materially from these estimates.

Note 2. Recent Accounting Pronouncements
Accounting Pronouncements Recently Adopted
In September 2022, the Financial Accounting Standards Board issued an accounting standards update (“ASU”) No. 2022-04, “Liabilities-Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations”, which requires annual and interim disclosures for entities that use supplier finance programs in connection with the purchase of goods and services. The ASU requires the Company to provide disclosure of outstanding obligations to such suppliers for all balance sheet dates presented beginning with the Company’s first quarter of 2024 and to provide certain rollforward information related to those obligations beginning in the Company’s first fiscal quarter of 2025. The ASU does not affect the recognition, measurement, or financial statement presentation of supplier finance program obligations. The Company adopted the guidance on the first day of fiscal year 2024, except for the rollforward information, which the Company is compiling and intends to provide beginning in fiscal year 2025. See Note 15, Supplier Finance Program, of the Notes to the Condensed Consolidated Financial Statements for information regarding the supplier finance program.

Disaggregated Revenue
The Company’s broad portfolio of technology and products address multiple end markets. Cloud is comprised primarily of products for public or private cloud environments and end customers, which the Company believes it is uniquely positioned to address as the only provider of both Flash and HDD. Through the Client end market, the Company provides its original equipment manufacturer (“OEM”) and channel customers a broad array of high-performance flash and hard drive solutions across personal computer, mobile, gaming, automotive, virtual reality headsets, at-home entertainment, and industrial spaces. The Consumer end market is highlighted by the Company’s broad range of retail and other end-user products, which capitalize on the strength of the Company’s product brand recognition and vast points of presence around the world.

IPR&D is initially accounted for as an indefinite-lived intangible asset. Once a project reaches technological feasibility, the Company reclassifies the balance to existing technology and begins to amortize the intangible asset over its estimated useful life. As of both September 29, 2023, and June 30, 2023, IPR&D included in intangible assets, net was $80 million. As of both September 29, 2023 and June 30, 2023, all other intangible assets were fully amortized.

Note 5. Fair Value Measurements and Investments
Financial Instruments Carried at Fair Value
Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three levels:
Level 1. Quoted prices in active markets for identical assets or liabilities.
Level 2. Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3. Inputs that are unobservable for the asset or liability and that are significant to the fair value of the assets or liabilities.
The following tables present information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of September 29, 2023 and June 30, 2023, and indicate the fair value hierarchy of the valuation techniques utilized to determine such values:

Investment in Flash Forward | 108 |  |  | 109 |
Total notes receivable and investments in Flash Ventures | $ | 1,245 |  |  | $ | 1,297 |

During the three months ended September 29, 2023 and September 30, 2022, the Company made net payments to Flash Ventures of $0.9 billion and $1.0 billion, respectively, for purchased flash-based memory wafers and net loans.
The Company makes, or will make, loans to Flash Ventures to fund equipment investments for new process technologies and additional wafer capacity. The Company aggregates its Flash Ventures’ notes receivable into one class of financing receivables due to the similar ownership interest and common structure in each Flash Venture entity. For all reporting periods presented, no loans were past due and no loan impairments were recorded. The Company’s notes receivable from each Flash Ventures entity, denominated in Japanese yen, are secured by equipment owned by that Flash Ventures entity.
As of September 29, 2023 and June 30, 2023, the Company had accounts payable balances due to Flash Ventures of $277 million and $292 million, respectively.
The Company’s maximum reasonably estimable loss exposure (excluding lost profits) as a result of its involvement with Flash Ventures, based upon the Japanese yen to U.S. dollar exchange rate at September 29, 2023, is presented below. Investments in Flash Ventures are denominated in Japanese yen, and the maximum estimable loss exposure excludes any cumulative translation adjustment due to revaluation from the Japanese yen to the U.S. dollar.

The Company is obligated to pay for variable costs incurred in producing its share of Flash Ventures’ flash-based memory wafer supply, based on its three-month forecast, which generally equals 50% of Flash Ventures’ output. In addition, the Company is obligated to pay for half of Flash Ventures’ fixed costs regardless of the output the Company chooses to purchase. The Company is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Company is committed to fund 49.9% to 50.0% of each Flash Ventures entity’s capital investments to the extent that each Flash Ventures entity’s operating cash flow is insufficient to fund these investments.
Flash Ventures has historically operated near 100% of its manufacturing capacity. During 2023 and the three months ended September 29, 2023, as a result of flash market conditions, the Company temporarily reduced its utilization of its share of Flash Ventures’ manufacturing capacity to an abnormally low level to more closely align the Company’s flash-based wafer supply with projected demand. During the three months ended September 29, 2023, the Company incurred costs of $141 million associated with the reduction in utilization related to Flash Ventures, which was recorded as a charge to Cost of revenue. No such charges were incurred during the three months ended September 30, 2022.
The Company has facility agreements with Kioxia related to the construction and operation of Kioxia’s “K1” 300-millimeter wafer fabrication facility in Kitakami, Japan and a wafer fabrication facility in Yokkaichi, Japan, referred to as “Y7”. In connection with the start-up of these facilities, the Company has made prepayments toward future building depreciation. As of September 29, 2023, such prepayments aggregated $539 million and will be credited against future wafer charges.
Inventory Purchase Commitments with Flash Ventures. Purchase orders placed under Flash Ventures for up to three months are binding and cannot be canceled.
Research and Development Activities. The Company participates in common research and development (“R&D”) activities with Kioxia and is contractually committed to a minimum funding level. R&D commitments are immaterial to the Condensed Consolidated Financial Statements.
Off-Balance Sheet Liabilities
Flash Ventures sells to and leases back from a consortium of financial institutions a portion of its tools and has entered into equipment lease agreements of which the Company guarantees half or all of the outstanding obligations under each lease agreement. The lease agreements are subject to customary covenants and cancellation events related to Flash Ventures and each of the guarantors. The occurrence of a cancellation event could result in an acceleration of Flash Ventures’ obligations and a call on the Company’s guarantees.
The following table presents the Company’s portion of the remaining guarantee obligations under the Flash Ventures’ lease facilities in both Japanese yen and U.S. dollar-equivalent, based upon the Japanese yen to U.S. dollar exchange rate as of September 29, 2023.

The Company and Kioxia have agreed to mutually contribute to, and indemnify each other and Flash Ventures for, environmental remediation costs or liability resulting from Flash Ventures’ manufacturing operations in certain circumstances. The Company has not made any indemnification payments, nor recorded any indemnification receivables, under any such agreements. As of September 29, 2023, no amounts had been accrued in the Condensed Consolidated Financial Statements with respect to these indemnification agreements.

Note 12. Income Tax Expense
The Tax Cuts and Jobs Act (the “2017 Act”), enacted on December 22, 2017, includes a broad range of tax reform proposals affecting businesses. The Company completed its accounting for the tax effects of the enactment of the 2017 Act during the second quarter of 2019. However, the U.S. Treasury and the Internal Revenue Service (“IRS”) have issued tax guidance on certain provisions of the 2017 Act since the enactment date, and the Company anticipates the issuance of additional regulatory and interpretive guidance. The Company applied a reasonable interpretation of the 2017 Act along with the then-available guidance in finalizing its accounting for the tax effects of the 2017 Act. Any additional regulatory or interpretive guidance would constitute new information, which may require further refinements to the Company’s estimates in future periods.
On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, which contained significant law changes related to tax, climate, energy, and health care. The tax measures include, among other things, a corporate alternative minimum tax (“CAMT”) of 15% on corporations with three-year average annual adjusted financial statement income (“AFSI”) exceeding $1.0 billion. The corporate alternative minimum tax is effective for the Company beginning with fiscal year 2024. The Company is not subject to the CAMT of 15% for fiscal year 2024 as its average annual AFSI did not exceed $1.0 billion for the preceding three-year period.
The following table presents the Company’s Income tax expense and the effective tax rate:

| Three Months Ended |  |
| September 29, 2023 |  | September 30, 2022 |  |  |  |

Income (loss) before taxes | $ | (682) |  |  | $ | 84 |  |  |  |  |
Income tax expense | 3 |  |  | 57 |  |  |  |  |
Effective tax rate | — | % |  | 68 | % |  |  |  |

Beginning in 2023, the 2017 Act requires the Company to capitalize and amortize R&D expenses rather than expensing them in the year incurred. The tax effects related to the capitalization of R&D expenses are included in the effective tax rate for the three months ended September 29, 2023, but did not have a material impact on the Company’s effective tax rate.
The primary drivers of the difference between the effective tax rate for the three months ended September 29, 2023 and the U.S. Federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign-derived intangible income, credits, and tax holidays in Malaysia, the Philippines and Thailand that will expire at various dates during years 2024 through 2031. In addition, the effective tax rate for the three months ended September 29, 2023 includes the discrete effect of a net decrease of $30 million to the liability for unrecognized tax benefits, which includes interest and offsetting tax benefits, as a result of adjustments to align with IRS calculations.

In addition to the amounts noted above, interest and penalties related to unrecognized tax benefits are recognized in liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. Accrued interest and penalties included in the Company’s liability related to unrecognized tax benefits as of September 29, 2023 were $157 million. Of the aggregate unrecognized tax benefits, including interest and penalties, as of September 29, 2023, approximately $663 million could result in potential cash payments and the Company believes it is reasonably likely that payments of approximately $183 million may be made within the next twelve months and has classified that portion of these unrecognized tax benefits, including interest, in Income taxes payable on the Consolidated Balance Sheets as of September 29, 2023. The remaining payables related to unrecognized tax benefits are included in Other liabilities on the Condensed Consolidated Balance Sheets as of September 29, 2023.
The Company reached a final agreement with the IRS regarding notices of deficiency with respect to years 2008 through 2012 and tentatively reached a basis for resolving the notices of proposed adjustments with respect to years 2013 through 2015. As of September 29, 2023, the Company has recognized a liability for tax and interest of $183 million related to all years from 2008 through 2015. The change in this liability from the prior quarter liability of $753 million was the result of a payment of $363 million for tax and $160 million for interest with respect to years 2008 through 2012 as well as adjustments to align with IRS calculations. The Company expects to pay any remaining balance with respect to this matter within the next twelve months.
In connection with settlements for the years 2008 through 2015, the Company expects to realize reductions to its mandatory deemed repatriation tax obligations and tax savings from interest deductions in future years aggregating to approximately $168 million. Of this amount, $34 million of the interest savings from the interest paid with respect to years 2008 through 2012 is classified as a deferred tax asset due to interest expense limitation rules.
The Company believes that adequate provision has been made for any adjustments that may result from any other tax examinations. However, the outcome of such tax examinations cannot be predicted with certainty. If any issues addressed in the Company’s tax examinations are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. As of September 29, 2023, with the exception of the IRS matter discussed above, it was not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Company’s liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of the Company’s tax returns.

Note 13. Net Income (Loss) Per Common Share
The following table presents the computation of basic and diluted income (loss) per common share:

| Three Months Ended |  |
| September 29, 2023 |  |  | September 30, 2022 |  |  |  |
| (in millions, except per share data)
Net income (loss) | $ | (685) |  |  |  | $ | 27 |  |  |  |  |
Less: cumulative dividends on Preferred Stock | 15 |  |  |  | — |  |  |  |  |
Net income (loss) attributable to common shareholders | $ | (700) |  |  |  | $ | 27 |  |  |  |  |
Weighted average shares outstanding: |  |  |  |  |  |  |  |
Basic | 323 |  |  |  | 316 |  |  |  |  |
Employee stock options, RSUs, PSUs, and ESPP | — |  |  |  | 3 |  |  |  |  |
Diluted | 323 |  |  |  | 319 |  |  |  |  |
Net income (loss) per common share |  |  |  |  |  |  |  |
Basic | $ | (2.17) |  |  |  | $ | 0.09 |  |  |  |  |
Diluted | $ | (2.17) |  |  |  | $ | 0.08 |  |  |  |  |
Anti-dilutive potential common shares excluded | 15 |  |  |  | 8 |  |  |  |  |

Basic net income (loss) per share attributable to common shareholders is computed using (i) net income (loss) less (ii) dividends paid to holders of Preferred Shares less (iii) net income (loss) attributable to participating securities divided by (iv) weighted average basic shares outstanding. Diluted net income or loss per share attributable to common shareholders is computed as (i) basic net income (loss) attributable to common shareholders plus (ii) diluted adjustments to income allocable to participating securities divided by (iii) weighted average diluted shares outstanding. The "if-converted" method is used to determine the dilutive impact for the 1.50% convertible notes and the Preferred Shares. The treasury stock method is used to determine the dilutive impact of unvested restricted stock.
Potentially dilutive common shares include dilutive outstanding employee stock options, RSUs and PSUs, rights to purchase shares of common stock under the Company’s ESPP, shares issuable in connection with the 1.50% convertible notes due 2024, and the Preferred Shares. For the three months ended September 29, 2023, the Company recorded a net loss and all shares subject to outstanding equity awards were excluded from the calculation of diluted shares for those periods because their impact would have been anti-dilutive. For the three months ended September 30, 2022, the Company excluded common shares subject to certain outstanding equity awards from the calculation of diluted shares because their impact would have been anti-dilutive based on the Company’s average stock price during the period.

Note 14. Employee Termination, Asset Impairment, and Other
Business Realignment
The Company periodically incurs charges as part of the integration process of recent acquisitions and to realign its operations with anticipated market demand, primarily consisting of organization rationalization designed to streamline its business, reduce its cost structure and focus its resources. In this regard, in the three months ended September 29, 2023, the Company reassessed existing capacity development plans and made a decision to cancel certain projects to expand capacity in its Penang, Malaysia facility, resulting in the impairment of existing construction in progress and the recognition of a liability for certain contract termination costs. The Company has also taken actions to reduce the amount of capital invested in facilities, including the sale-leaseback of its facility in Milpitas, California in September 2023. The Company recorded the following net charges related to these actions for the periods noted below:

| Three Months Ended |  |  |  |
| September 29, 2023 |  | September 30, 2022 |  |  |  |  |  |

Note 15. Supplier Finance Program
The Company maintains a voluntary supplier finance program that provides participating suppliers with enhanced receivable options. The program allows participating suppliers of the Company, at their sole discretion and cost, to sell their receivables due from the Company to a third-party financial institution and receive early payment at terms negotiated between the supplier and the third-party financial institution. The Company’s vendor payment terms and amounts are not impacted by a supplier’s decision to participate in this program.
The Company’s current payment terms with its suppliers under these programs generally range from 60 to 90 days and payment terms that the Company negotiates with its suppliers are not impacted by whether a supplier participates in the program. The Company does not provide any guarantees to any third parties and no assets are pledged in connection with the arrangements.
The Company’s outstanding payment obligations to vendors eligible to participate under its supplier finance program were $39 million and $38 million as of September 29, 2023 and June 30, 2023, respectively, and are included within Accounts payable on the Company’s Condensed Consolidated Balance Sheets.

Tax
For disclosures regarding the status of statutory notices of deficiency issued by the IRS with regard to tax years 2008 through 2015, see Note 12, Income Tax Expense.
Other Matters
In the normal course of business, the Company is subject to legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties, management believes that any monetary liability or financial impact to the Company from these matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, any monetary liability and financial impact to the Company from these matters could differ materially from the Company’s expectations.

Note 17. Subsequent Events
Separation of Business Units
On October 30, 2023, the Company announced that its Board of Directors authorized management to pursue a plan to separate its HDD and Flash business units into two independent public companies. The completion of the separation is subject to certain conditions, including final approval by its Board of Directors. The Company is targeting to complete the separation of the business units in the second half of calendar year 2024.
Convertible Notes and Related Capped Call Transactions
On November 3, 2023, the Company issued $1.60 billion aggregate principal amount of convertible senior notes which bear interest at an annual rate of 3.00% and mature on November 15, 2028, unless earlier repurchased, redeemed or converted (the “2028 Convertible Notes”). The 2028 Convertible Notes are jointly and severally guaranteed by each of the Company’s wholly-owned subsidiaries that guarantees the 2026 Notes (currently, Western Digital Technologies, Inc.).
The 2028 Convertible Notes are convertible at an initial conversion price of approximately $52.20 per share of common stock. Prior to August 15, 2028, the 2028 Convertible Notes are convertible only upon the occurrence of certain events and during certain periods. Upon any conversion of the 2028 Convertible Notes, the Company will pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination thereof, at the Company’s election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the notes being converted.
In connection with the debt issuance, the Company used approximately $155 million of the net proceeds of the 2028 Convertible Notes offering to pay the cost of entering into capped call contracts with a cap price of approximately $70.26 per share to hedge the potential dilution impact of the notes’ conversion feature.
Contemporaneously with the issuance of the 2028 Convertible Notes, the Company entered into individually negotiated transactions with certain holders of the Company’s existing 2024 Convertible Notes to repurchase approximately $508 million aggregate principal amount of such notes at an immaterial discount.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis contains forward-looking statements within the meaning of the federal securities laws, and should be read in conjunction with the disclosures we make concerning risks and other factors that may affect our business and operating results. You should read this information in conjunction with the unaudited Condensed Consolidated Financial Statements and the notes thereto included in this Quarterly Report on Form 10-Q, and the audited Consolidated Financial Statements and notes thereto included in Part II, Item 8 of our Annual Report on Form 10‑K for the fiscal year ended June 30, 2023. See also “Forward-Looking Statements” immediately prior to Part I, Item 1 in this Quarterly Report on Form 10-Q.
Unless otherwise indicated, references herein to specific years and quarters are to our fiscal years and fiscal quarters. As used herein, the terms “we,” “us,” “our,” and the “Company” refer to Western Digital Corporation and its subsidiaries.
Our Company
We are on a mission to unlock the potential of data by harnessing the possibility to use it. We are a leading developer, manufacturer, and provider of data storage devices based on both NAND flash and hard disk drive technologies. With dedicated flash-based products (“Flash”) and hard disk drives (“HDD”) business units driving advancements in storage technologies, our broad and ever-expanding portfolio delivers powerful Flash and HDD storage solutions for everyone from students, gamers, and home offices to the largest enterprises and public clouds to capture, preserve, access, and transform an ever-increasing diversity of data.
Our broad portfolio of technology and products address our multiple end markets: “Cloud”, “Client” and “Consumer”. Cloud represents a large and growing end market comprised primarily of products for public or private cloud environments and enterprise customers, which we believe we are uniquely positioned to address as the only provider of both Flash and HDD. Through the Client end market, we provide our original equipment manufacturer (“OEM”) and channel customers a broad array of high-performance flash and hard drive solutions across personal computer, mobile, gaming, automotive, virtual reality headsets, at-home entertainment, and industrial spaces. The Consumer end market is highlighted by our broad range of retail and other end-user products, which capitalize on the strength of our product brand recognition and vast points of presence around the world.
Our fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, we report a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2024, which will end on June 28, 2024, and fiscal year 2023, which ended June 30, 2023, are each comprised of 52 weeks, with all quarters presented consisting of 13 weeks.

Key Developments
Separation of Business Units
On October 30, 2023, we announced that our Board of Directors had completed its strategic review of our business and, after evaluating a comprehensive range of alternatives, authorized us to pursue a plan to separate our HDD and Flash business units to create two independent, public companies. We believe the separation will better position each business unit to execute innovative technology and product development, capitalize on unique growth opportunities, extend respective leadership positions, and operate more efficiently with distinct capital structures. The completion of the planned separation is subject to certain conditions, including final approval by our Board of Directors. We are targeting to complete the separation of the businesses in the second half of calendar year 2024.
Financing Activities
In August 2023, we drew $600 million principal amount (the “Delayed Draw Term Loan”) under a loan agreement we entered into in January 2023 and amended in June 2023 (the “Delayed Draw Term Loan Agreement”), which allowed us to draw a single loan of up to $600 million through August 14, 2023. Proceeds from this loan were primarily used for payments on tax liability to the IRS for the years 2008 through 2012. Borrowings on this loan will mature on June 28, 2024.
On November 3, 2023, we issued $1.60 billion aggregate principal amount of convertible senior notes which bear interest at an annual rate of 3.00% and mature on November 15, 2028, unless earlier repurchased, redeemed or converted (the “2028 Convertible Notes”). We received net proceeds of approximately $1.56 billion after issuance costs. Contemporaneously with the issuance of the 2028 Convertible Notes, we entered into individually negotiated transactions with certain holders of our existing 1.50% convertible senior notes due 2024 (the “2024 Convertible Notes”), which mature on February 1, 2024, to repurchase approximately $508 million aggregate principal amount of such notes at an immaterial discount using net proceeds from the offering of the 2028 Convertible Notes. In connection with the issuance of the 2028 Convertible Notes, we also used approximately $155 million of the net proceeds from the offering to pay the cost of entering into capped call contracts with a cap price of approximately $70.26 to hedge the potential dilution impact of the conversion feature. The remaining net proceeds from the offering of the 2028 Convertible Notes will be used primarily to settle the remaining 2024 Convertible Notes.
Additional information regarding our indebtedness, including the principal repayment terms, interest rates, covenants and other key terms of our outstanding indebtedness, and additional information on the terms of our convertible preferred shares and the 2028 Convertible Notes is included in Part II, Item 8, Note 8, Debt, and Note 13, Shareholders’ Equity and Convertible Preferred Stock, of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023 and Note 17, Subsequent Events, of the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Sale-Leaseback
In September 2023, we completed a sale and leaseback of our facility in Milpitas, California. We received net proceeds of $191 million in cash and recorded a gain of $85 million on the sale. We are leasing back the facility at an annual lease rate of $16 million for the first year, increasing by 3% per year thereafter through January 1, 2039. The lease includes three 5-year renewal options and one 4-year renewal option for the ability to extend through December 2057.
Asset Impairment and Contract Termination Costs
During the three months ended September 29, 2023, we reassessed our existing capacity development plans and made a decision to cancel certain projects to expand capacity in our Penang, Malaysia facility, resulting in a $94 million impairment of existing construction in progress and recognition of a $29 million liability for certain contract termination costs.
Tax Resolution
As previously disclosed, we reached a final agreement with the IRS and received notices of deficiency with respect to years 2008 through 2012 and have tentatively reached a basis for resolving the notices of proposed adjustments with respect to years 2013 through 2015. During the three months ended September 29, 2023, we made payments aggregating $523 million for tax and interest with respect to years 2008 through 2012 and have a remaining liability of $183 million as of September 29, 2023 related to all years from 2008 through 2015. We expect to pay any remaining balance with respect to this matter within the next twelve months. Additional information regarding these settlements and our assessment of the potential tax and interest payments we expect to pay in connection with the settlements is provided in our discussion of Income tax expense in our results of operations below, as well as in Part I, Item 1, Note 12, Income Tax Expense, of the Notes to the Condensed Consolidated Financial Statements, and in the “Short- and Long-term Liquidity - Unrecognized Tax Benefits” section below.

Operational Update
Macroeconomic factors such as inflation, higher interest rates and recession concerns have softened demand for our products, with certain customers reducing purchases as they adjust their production levels and right-size their inventories. As a result, we and our industry have been experiencing a supply-demand imbalance, which has resulted in reduced shipments and negatively impacted pricing, particularly in Flash. While the supply-demand imbalance has recently started to show signs of stabilization, particularly in Client and Consumer, we continue to face a dynamic market environment. To adapt to these conditions, we have scaled back on capital expenditures, consolidated production lines and reduced production bit growth since the beginning of 2023 in order to better align with market demand and have also implemented measures to reduce operating expenses. These actions have resulted in incremental charges for employee termination, asset impairment and other, and manufacturing underutilization charges in Flash and HDD, and are expected to continue to negatively impact near-term results. Notwithstanding the current supply-demand imbalance, we believe digital transformation will continue to drive long-term growth for data storage in both Flash and HDD and believe that the actions we are taking will position us to capitalize on market conditions when they improve to address long-term growth opportunities in data storage across all our end markets.
We will continue to actively monitor developments impacting our business and may take additional responsive actions that we determine to be in the best interest of our business and stakeholders.
See Part I, Item 1A, Risk Factors, of our Annual Report on Form 10-K for the year ended June 30, 2023 for more information regarding the risks we face as a result of macroeconomic conditions and supply chain disruptions.

Flash revenue decreased 10% for the three months ended September 29, 2023 from the comparable period in the prior year primarily as a result of a 39% decline in average selling prices per gigabyte caused by the macroeconomic pressures noted previously, partially offset by an increase in exabytes shipped.

Table of Contents
HDD revenue decreased 41% for the three months ended September 29, 2023, from the comparable period in the prior year primarily as a result of a 42% decline in exabytes shipped, which was substantially all driven by lower shipments to customers in our Cloud end market.
The 52% decrease in Cloud revenue for the three months ended September 29, 2023 from the comparable period in the prior year was substantially all driven by lower volume in HDD and Flash. In Client, the 7% decrease in revenue for the three months ended September 29, 2023 from the comparable period in the prior year primarily reflected approximately 57 percentage points of decline from lower pricing, driven by Flash, which was largely offset by an increase in volume, also in Flash. In Consumer, the 8% increase in revenue for the three months ended September 29, 2023 from the comparable period in the prior year primarily reflected approximately 44 percentage points of increase from higher volume, driven by Flash,which was largely offset by a decline in pricing, also in Flash.
The changes in net revenue by geography for the three months ended September 29, 2023 from the comparable period in the prior year reflected a larger decline in Americas from lower Cloud revenue in this region as our Cloud customers reduced purchases to align with current market demand, as well as routine variations in the mix of business.
Our top 10 customers accounted for 44% of our net revenue for the three months ended September 29, 2023, compared to 52% of our net revenue for the three months ended September 30, 2022. For each of the three months ended September 29, 2023 and September 30, 2022, no single customer accounted for 10% or more of our net revenue.
Consistent with standard industry practice, we have sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. These programs represented 20% of gross revenue for the three months ended September 29, 2023, and 19% of gross revenue for the three months ended September 30, 2022. The amounts attributed to our sales incentive and marketing programs generally vary according to several factors including industry conditions, list pricing strategies, seasonal demand, competitor actions, channel mix and overall availability of products. Changes in future customer demand and market conditions may require us to adjust our incentive programs as a percentage of gross revenue.
Gross Profit and Gross Margin
Consolidated gross profit decreased by $882 million for the three months ended September 29, 2023 from the comparable period in the prior year, which primarily reflected the decrease in revenue described above as well as charges of approximately $225 million for manufacturing underutilization and related charges ($142 million in Flash and $83 million in HDD) and a write down of certain Flash inventory to the lower of cost or market value during the three months ended September 29, 2023. Consolidated gross margin decreased 23 percentage points for the three months ended September 29, 2023 from the comparable period in the prior year, with approximately 8 percentage points of the decline due to the net charges noted above and the remainder primarily driven by the lower average selling prices per gigabyte in Flash. Flash gross margin decreased by approximately 35 percentage points year over year, with approximately 9 percentage points of the decline due to the net charges noted above and the remainder driven by the lower average selling prices per gigabyte. HDD gross margin decreased by 6 percentage points year over year, with approximately 6 percentage points of the decline due to the net charges noted above.
Operating Expenses
Research and development (“R&D”) expense decreased $121 million for the three months ended September 29, 2023 from the comparable period in the prior year. The decline was primarily driven by reductions in variable compensation expenses, headcount, and material use as we took actions to reduce expenses in the current environment.
Selling, general and administrative (“SG&A”) expense decreased $40 million for the three months ended September 29, 2023 from the comparable period in the prior year. The decline was primarily driven by reductions in headcount, variable compensation expenses, and a decrease in intangible amortization expense.
Employee termination, asset impairment and other increased $33 million for the three months ended September 29, 2023 from the comparable period in the prior year. The increase was primarily driven by asset impairments caused by project cancellations, partially offset by a gain on the sale-leaseback of our Milpitas, California facility. For information regarding Employee termination, asset impairment and other, see Part I, Item 1, Note 14, Employee Termination, Asset Impairment, and Other of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Interest and Other Income (Expense)
Total interest and other expense, net increased $12 million for the three months ended September 29, 2023 from the comparable period in the prior year, reflecting higher interest expenses resulting from increases in interest rates and the drawdown of our Delayed Draw Term Loan discussed in “Key Developments-Financing Activities” above.
Income Tax Expense
The Tax Cuts and Jobs Act (the “2017 Act”) includes a broad range of tax reform proposals affecting businesses. We completed our accounting for the tax effects of the enactment of the 2017 Act during the second quarter of fiscal 2019. However, the U.S. Treasury and the IRS have issued tax guidance on certain provisions of the 2017 Act since the enactment date, and we anticipate the issuance of additional regulatory and interpretive guidance. We applied a reasonable interpretation of the 2017 Act along with the then-available guidance in finalizing our accounting for the tax effects of the 2017 Act. Any additional regulatory or interpretive guidance would constitute new information, which may require further refinements to our estimates in future periods.
On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, which contained significant legal changes related to tax, climate, energy, and health care. The tax measures include, among other things, a corporate alternative minimum tax (“CAMT”) of 15% on corporations with three-year average annual adjusted financial statement income (“AFSI”) exceeding $1.0 billion. The CAMT is effective for us beginning with fiscal year 2024. We are not subject to the CAMT of 15% for fiscal year 2024 as our annual average AFSI did not exceed $1.0 billion for the preceding three-year period.
The following table sets forth Income tax information from our Condensed Consolidated Statements of Operations by dollar and effective tax rate:

| Three Months Ended |  |
| September 29, 2023 |  | September 30, 2022 |  |  |  |
| $ in millions
Income (loss) before taxes | $ | (682) |  |  | $ | 84 |  |  |  |  |
Income tax expense | 3 |  |  | 57 |  |  |  |  |
Effective tax rate | — | % |  | 68 | % |  |  |  |

Since the beginning of fiscal year 2023, the 2017 Act has required us to capitalize and amortize R&D expenses rather than expensing them in the year incurred. The tax effects related to the capitalization of R&D expenses are included in the effective tax rate for the three months ended September 29, 2023, but did not have a material impact on our effective tax rate. The primary drivers of the difference between the effective tax rate for the three months ended September 29, 2023 and the U.S. Federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign-derived intangible income, credits, and tax holidays in Malaysia, the Philippines and Thailand that will expire at various dates during fiscal years 2024 through 2031. In addition, the effective tax rate for the three months ended September 29, 2023 includes the discrete effect of a net decrease of $30 million to the liability for unrecognized tax benefits, which includes interest and offsetting tax benefits, as a result of adjustments to align with IRS calculations.
The primary drivers of the difference between the effective tax rate for the three months ended September 30, 2022 and the U.S. Federal statutory rate of 21% were the relative mix of earnings and losses by jurisdiction, the deduction for foreign derived intangible income, credits, and tax holidays in Malaysia, the Philippines and Thailand.
Our future effective tax rate is subject to future regulatory developments and changes in the mix of our U.S. earnings compared to foreign earnings. The 2017 Act requires us to capitalize and amortize R&D expenses rather than expensing them in the year incurred. As described above, these capitalized expenses are included in our effective tax rate for the three months ended September 29, 2023, but did not have a material impact on the effective tax rate in those periods due to our reduced profitability. Mandatory capitalization of R&D is expected to materially increase our effective tax rate and taxes paid in future periods, if not repealed or otherwise modified. In addition, our total tax expense in future years may also vary as a result of discrete items such as excess tax benefits or deficiencies.

Liquidity and Capital Resources
The following table summarizes our statements of cash flows:

| Three Months Ended |  |
| September 29, 2023 |  | September 30, 2022 |  |
| (in millions)
Net cash provided by (used in): |  |  |  |  |
Operating activities | $ | (626) |  |  | $ | 6 |  |  |

Effect of exchange rate changes on cash | (3) |  |  | (10) |  |  |
Net increase (decrease) in cash and cash equivalents | $ | 9 |  |  | $ | (278) |  |  |

We reached a final agreement with the IRS and received notices of deficiency with respect to years 2008 through 2012 and have tentatively reached a basis for resolving the notices of proposed adjustments with respect to years 2013 through 2015. During the three months ended September 29, 2023, the Company made payments of $363 million for tax and $160 million for interest with respect to years 2008 through 2012 and recorded adjustments to align with IRS calculations, resulting in remaining liability of $183 million as of September 29, 2023, related to all years from 2008 through 2015. The Company expects to pay any remaining balance with respect to this matter within the next twelve months.
In connection with settlements for the years 2008 through 2015, we expect to realize reductions to our mandatory deemed repatriation tax obligations and tax savings from interest deductions in future years aggregating to $168 million. Of this amount, $34 million of interest savings from the interest paid with respect to years 2008 through 2012 is classified as a deferred tax asset due to interest expense limitation rules. See Part I, Item 1, Note 12, Income Tax Expense, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q for further details.
We have an existing shelf registration statement (the “Shelf Registration Statement”) filed with the Securities and Exchange Commission that expires in August 2024, which allows us to offer and sell shares of common stock, preferred stock, warrants, and debt securities. We may use the Shelf Registration Statement or other capital sources, including other offerings of equity or debt securities or the credit markets, to satisfy future financing needs, including planned or unanticipated capital expenditures, investments, debt repayments or other expenses. Any such additional financing will be subject to market conditions and may not be available on terms acceptable to us or at all.
As noted previously, we have been scaling back on capital expenditures, consolidating production lines and reducing bit growth to align with market demand. We reduced our expenditures for property, plant and equipment for our company plus our portion of the capital expenditures by our Flash Ventures joint venture with Kioxia for its operations to approximately $1.4 billion in 2023 from approximately $1.5 billion in 2022. After consideration of the Flash Ventures’ lease financing of its capital expenditures and net operating cash flow, we reduced our net cash used for our purchases of property, plant and equipment and net activity in notes receivable relating to Flash Ventures to $793 million in 2023 from $1.2 billion in 2022. We currently expect the capital expenditures for 2024 to be less than 2023.
We believe our Cash and cash equivalents, including the proceeds from the drawdown of the Delayed Draw Term Loan, the net proceeds we received from the sale and leaseback of our Milpitas facility, and the proceeds from the issuance of the 2028 Convertible Notes, each as discussed in “Key Developments” above, and our available revolving credit facility will be sufficient to meet our working capital, debt and capital expenditure needs for at least the next twelve months and for the foreseeable future thereafter, as we navigate the current market downturn before returning to profitable operations and positive cash flows when the market normalizes. We believe we can also access the various debt capital markets to further supplement our liquidity position if necessary. Our ability to sustain our working capital position is subject to a number of risks that we discuss in Part II, Item 1A, Risk Factors, in this Quarterly Report on Form 10-Q and in Part I, Item 1A, Risk Factors, in our Annual Report on Form 10-K for the year ended June 30, 2023.
A total of $1.43 billion and $1.28 billion of our Cash and cash equivalents was held by our foreign subsidiaries as of September 29, 2023 and June 30, 2023, respectively. There are no material tax consequences that were not previously accrued for on the repatriation of this cash.

Table of Contents
Our cash equivalents are primarily invested in money market funds that invest in U.S. Treasury securities and U.S. Government agency securities. In addition, from time to time, we also invest directly in certificates of deposit, asset-backed securities and corporate and municipal notes and bonds.
Operating Activities
Net cash provided by or used in operating activities primarily consists of net income or loss, adjusted for non-cash charges, plus or minus changes in operating assets and liabilities. Net cash used for changes in operating assets and liabilities was $132 million for the three months ended September 29, 2023, as compared to $329 million for the three months ended September 30, 2022, which largely reflects the reduction in operating assets resulting from the reduction in volume of our business, partially offset by payments made on the IRS matter, as discussed above. Changes in our operating assets and liabilities are largely affected by our working capital requirements, which are dependent on our volume of business and the effective management of our cash conversion cycle as well as timing of payments for taxes. Our cash conversion cycle measures how quickly we can convert our products into cash through sales. The cash conversion cycles were as follows (in days):

| Three Months Ended |  |
| September 29, 2023 |  | September 30, 2022 |  |  |  |
Days sales outstanding | 48 |  |  | 59 |  |  |  |  |
Days in inventory | 120 |  |  | 128 |  |  |  |  |
Days payable outstanding | (54) |  |  | (65) |  |  |  |  |
Cash conversion cycle | 114 |  |  | 122 |  |  |  |  |

Changes in days sales outstanding (“DSO”) are generally due to the timing of shipments. Changes in days in inventory (“DIO”) are generally related to the timing of inventory builds, including staging of inventory to meet expected future demand. Changes in days payable outstanding (“DPO”) are generally related to production volume and the timing of purchases during the period. From time to time, we modify the timing of payments to our vendors. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances. Generally, we make payment term modifications through negotiations with our vendors or by granting to, or receiving from, our vendors’ payment term accommodations.
For the three months ended September 29, 2023, DSO decreased by 11 days from the comparable period in the prior year, primarily reflecting the timing of shipments and customer collections. DIO decreased by 8 days from the comparable period in the prior year, primarily reflecting lower production volumes in the current year and an increase in products shipped. DPO decreased by 11 days from the comparable period in the prior year primarily due to reductions in production volume and capital expenditures as well as routine variations in the timing of purchases and payments during the period.
Investing Activities
Net cash provided by investing activities for the three months ended September 29, 2023 primarily consisted of $69 million in proceeds from disposals of assets, which includes the proceeds from our sale-leaseback of our Milpitas, California facility, net of capital expenditures, and $13 million in proceeds from net activity related to Flash Ventures. Net cash used in investing activities for the three months ended September 30, 2022 primarily consisted of $320 million in capital expenditures, net of disposals, partially offset by $99 million in proceeds from activity related to Flash Ventures.
Financing Activities
During the three months ended September 29, 2023, net cash provided by financing activities primarily consisted of $600 million in proceeds from the drawdown of the Delayed Draw Term Loan, partially offset by $43 million used for taxes paid on vested stock awards under employee stock plans. During the three months ended September 30, 2022 cash flows from financing activities primarily consisted of $50 million used for taxes paid on vested stock awards under employee stock plans, while we drew and repaid $300 million under our revolving credit facility within the period.

Off-Balance Sheet Arrangements
Other than the commitments related to Flash Ventures incurred in the normal course of business and certain indemnification provisions (see “Short and Long-term Liquidity-Purchase Obligations and Other Commitments” below), we do not have any other material off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any other obligation arising out of a material variable interest in an unconsolidated entity. We do not have any majority-owned subsidiaries that are not included in the Condensed Consolidated Financial Statements. Additionally, with the exception of Flash Ventures and our joint venture with Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd., we do not have an interest in, or relationships with, any variable interest entities.

(1)Principal portion of debt, excluding discounts and issuance costs.
(2)Includes reimbursement for depreciation and lease payments on owned and committed equipment, funding commitments for loans and equity investments and payments for other committed expenses, including R&D and building depreciation. Funding commitments assume no additional operating lease guarantees. Additional operating lease guarantees can reduce funding commitments.
Dividend rights
On January 31, 2023, we issued an aggregate of 900,000 shares of Series A Preferred Stock for an aggregate purchase price of $900 million. These shares are entitled to cumulative preferred dividends. See Part I, Item 1, Note 11, Shareholders’ Equity and Convertible Preferred Stock, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q for more information regarding the dividend provisions.
Debt
In addition to our existing debt, as of September 29, 2023, we had $2.25 billion available for borrowing under our revolving credit facility until January 2027, subject to customary conditions under the loan agreement. Furthermore, we issued 2028 Convertible Notes as noted in “Key Developments-Financing Activities” above. The agreements governing our credit facilities each include limits on secured indebtedness and certain types of unsecured subsidiary indebtedness and require us and certain of our subsidiaries to provide guarantees and collateral to the extent the conditions providing for such guarantees and collateral are met. Additional information regarding our indebtedness, including information about availability under our revolving credit facility and the principal repayment terms, interest rates, covenants, collateral and other key terms of our outstanding indebtedness, is included in Part II, Item 8, Note 8, Debt, of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended June 30, 2023 and Note 17, Subsequent Events, of the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
The loan agreements governing our revolving credit facility, our Term Loan A-2 due 2027, and our Delayed Draw Term Loan require us to comply with certain financial covenants, consisting of a leverage ratio, a minimum liquidity and a free cash flow requirement. As of September 29, 2023, we were in compliance with these financial covenants.
Flash Ventures
Flash Ventures sells to and leases back from a consortium of financial institutions a portion of its tools and has entered into equipment lease agreements of which we guarantee half or all of the outstanding obligations under each lease agreement. The leases are subject to customary covenants and cancellation events that relate to Flash Ventures and each of the guarantors. The occurrence of a cancellation event could result in an acceleration of the lease obligations and a call on our guarantees. As of September 29, 2023, we were in compliance with all covenants under these Japanese lease facilities. See Part I, Item 1, Note 9, Related Parties and Related Commitments and Contingencies, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q for information regarding Flash Ventures.

Table of Contents
Purchase Obligations and Other Commitments
In the normal course of business, we enter into purchase orders with suppliers for the purchase of components used to manufacture our products. These purchase orders generally cover forecasted component supplies needed for production during the next quarter, are recorded as a liability upon receipt of the components, and generally may be changed or canceled at any time prior to shipment of the components. We also enter into long-term agreements with suppliers that contain fixed future commitments, which are contingent on certain conditions such as performance, quality and technology of the vendor’s components. These arrangements are included under “Purchase obligations and other commitments” in the table above.
Mandatory Deemed Repatriation Tax
The following is a summary of our estimated mandatory deemed repatriation tax obligations that are payable in the following years:

|  | September 29, 2023
|  | (in millions)
Remainder of fiscal 2024 |  | $ | 199 |
2025 |  | 265 |
2026 |  | 199 |
Total |  | $ | 663 |

Unrecognized Tax Benefits
As of September 29, 2023, the liability for unrecognized tax benefits (excluding accrued interest and penalties) was $672 million. Accrued interest and penalties related to unrecognized tax benefits are recognized in liabilities for uncertain tax positions and are recorded in the provision for income taxes. Accrued interest and penalties included in our liability related to unrecognized tax benefits as of September 29, 2023 was $157 million. Of these amounts, approximately $663 million could result in potential cash payments.
As noted above, we reached a final agreement with the IRS regarding notices of deficiency with respect to years 2008 through 2012 and have tentatively reached a basis for resolving the notices of proposed adjustments with respect to years 2013 through 2015. During the three months ended September 29, 2023, we made payments of $363 million for tax and $160 million for interest with respect to years 2008 through 2012 and recorded adjustments to align with IRS calculations, resulting in remaining liability of $183 million as of September 29, 2023 related to all years from 2008 through 2015. We expect to pay any remaining balance with respect to this matter within the next twelve months.
In connection with settlements for the years 2008 through 2015, we expect to realize reductions to our mandatory deemed repatriation tax obligations and tax savings from interest deductions in future years aggregating to approximately $168 million. Of this amount, $34 million of interest savings from the interest paid with respect to years 2008 through 2012 is classified as a deferred tax asset due to interest expense limitation rules.
Mandatory Research and Development Expense Capitalization
Since the beginning of 2023, the 2017 Act has required us to capitalize and amortize R&D expenses rather than expensing them in the year incurred, which is expected to result in materially higher cash tax payments in future periods, if not repealed or otherwise modified.
Foreign Exchange Contracts
We purchase foreign exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, liabilities and commitments for Operating expenses and product costs denominated in foreign currencies. See Part I, Item 3, Quantitative and Qualitative Disclosures About Market Risk included in this Quarterly Report on Form 10-Q for additional information.

Table of Contents
Indemnifications
In the ordinary course of business, we may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of agreements, products or services to be provided by us, environmental compliance or from intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and certain of our officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. We maintain director and officer insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and officers in certain circumstances.
It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Such indemnification agreements may not be subject to maximum loss clauses. Historically, we have not incurred material costs as a result of obligations under these agreements.
Recent Accounting Pronouncements
For a description of recently issued and adopted accounting pronouncements, including the respective dates of adoption and expected effects on our results of operations and financial condition, see Part I, Item 1, Note 2, Recent Accounting Pronouncements, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.
Critical Accounting Policies and Estimates
We have prepared the accompanying unaudited Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States (U.S. GAAP). The preparation of the financial statements requires the use of judgments and estimates that affect the reported amounts of revenues, expenses, assets, liabilities and shareholders’ equity. We have adopted accounting policies and practices that are generally accepted in the industry in which we operate. If these estimates differ significantly from actual results, the impact to the Condensed Consolidated Financial Statements may be material.
There have been no material changes in our critical accounting policies and estimates from those disclosed in our Annual Report on Form 10‑K for the year ended June 30, 2023. Please refer to Part II, Item 7 of our Annual Report on Form 10‑K for the year ended June 30, 2023 for a discussion of our critical accounting policies and estimates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
Except as disclosed below, there have been no material changes to our market risk during the three months ended September 29, 2023. See Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk in our Annual Report on Form 10-K for the year ended June 30, 2023 for further information about our exposure to market risk.
Foreign Currency Risk
We have performed sensitivity analyses as of September 29, 2023 and June 30, 2023 using a modeling technique that measures the change in the fair values arising from a hypothetical 10% adverse moveme nt in the levels of foreign currency exchange rates relative to the U.S. dollar, with all other variables held constant. The analyses cover all of our foreign currency derivative contracts used to offset the underlying exposures. The foreign currency exchange rates used in performing the sensitivity analyses were based on market rates in effect at September 29, 2023 and June 30, 2023. The sensitivity analyses indicated that a hypothetical 10% adverse movement in foreign currency exchange rates relative to the U.S. dollar would result in a foreign exchange fair value loss of $250 million and $285 million at September 29, 2023 and June 30, 2023, respectively.
Interest Rate Risk
We have generally held a balance of fixed and variable rate debt. As of September 29, 2023, our variable rate debt outstanding consists of our Term Loan A-2 and Delayed Draw Term Loan, which are based on various index rates as discussed further in Note 7, Debt, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q. As of September 29, 2023, the outstanding balance on our variable rate debt was $3.3 billion and a one percent increase in the variable rate of interest would increase annual interest expense by $33 million.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As required by Rule 13a-15(b) promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective.
Changes in Internal Controls over Financial Reporting
There has been no change in our internal control over financial reporting during the first quarter of fiscal year 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

We have described under the heading “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended June 30, 2023 a number of risks and uncertainties that could cause our actual results of operations and financial condition to vary materially from past, or from anticipated future, results of operations and financial condition. Except as discussed below, there have been no material changes from these risk factors previously described in our Annual Report on Form 10-K for the year ended June 30, 2023. These risks and uncertainties are not the only risks facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect our business, financial condition, results of operations or the market price of our common stock.
The proposed separation of our HDD and Flash business units into two independent public companies is subject to various risks and uncertainties and may not be completed in accordance with the expected plans or anticipated timeline, or at all.
On October 30, 2023, we announced that our Board of Directors had completed its review of potential strategic alternatives and had unanimously approved pursuing a plan to separate the Flash business unit from our remaining hard disk drive technology business (the “Separation”). The Separation is intended to be structured in a tax-free manner and is targeted for completion in the second half of the calendar year 2024. No assurance can be given as to whether the Separation will occur, when any such transaction will be approved or when any separation may be completed. Furthermore, while we are exploring the Separation of our Flash business unit, the specific assets, liabilities and entities to be separated have not yet been determined and may change. We may determine to abandon any efforts with respect to the Separation at any time for any reason.
The form or other terms of the Separation may change over time, including with respect to the scope of the businesses to be separated or retained by us. The final determination to separate is subject to Board approval, the execution of definitive documentation, receipt of opinions or rulings as to the tax-free nature of the Separation and satisfaction of customary conditions, including the effectiveness of appropriate filings with the SEC, the completion of audited financial statements and the availability of financing. Additionally, no assurance can be given that the intended tax treatment will be achieved or that shareholders will not incur substantial tax liabilities in connection with the Separation. The failure to satisfy any of these conditions could delay the completion of the Separation for a significant period of time or prevent it from occurring at all.
Various factors, including changes in the competitive conditions of our markets, changes in financial markets and economic conditions, failure to obtain any third party consents that may be required for the Separation, delays in obtaining tax opinions or rulings, material or unanticipated tax liability for our shareholders, us, and/or the Flash business unit, and other challenges in executing the separation of the two businesses, could delay or prevent the completion of the Separation or cause it to occur on terms or conditions that are different or less favorable than expected.
Further, our Board of Directors could decide, either because of a failure of conditions or because of market or other factors, to abandon the separation of our Flash business unit.
Our review of the Separation has and will continue to involve significant time, expense and resources and could disrupt or adversely affect our business.
Executing the Separation of our Flash business unit has and will continue to require significant time and attention from our senior management and employees and may divert their attention from operating and growing our business in ways that could adversely affect our business, financial condition and results of operations. Our employees may also be distracted due to uncertainty about their future roles with the separated companies, and customers or suppliers could delay or defer decisions or may end their relationships with us.

In addition, we have incurred and will continue to incur expenses in connection with our strategic review and the consideration of the Separation and expect that the process of reviewing the Separation and executing the Separation, if any, will be time-consuming and involve significant additional costs and expenses, which may not yield a benefit if the Separation is not completed. If pursued, we will also incur ongoing costs and dis-synergies in connection with, or as a result of, the Separation and related restructuring transactions, including costs of operating as independent, publicly traded companies that the two businesses will no longer be able to share.
Any of the above factors could cause the Separation (or the failure to execute the Separation) to have a material adverse effect on our business, financial condition, results of operations and the trading price of our common stock and/or other securities.
The Separation may not achieve the anticipated benefits and could expose us to new risks, including with respect to our existing indebtedness.
We may not realize any strategic, financial, operational, or other benefits from the Separation of our Flash business unit. We cannot predict with certainty if or when anticipated benefits will occur or the extent to which they will be achieved. If the Separation is completed, our operational and financial profile will change and we will face new risks. If the Separation is completed, we will be a smaller and less-diversified company and may be more vulnerable to changing market conditions. While we believe that the Separation will position each company to better unlock its full standalone long-term potential, we cannot assure you that following the Separation we will be successful. Further, there can be no assurance that the combined value of the shares of the two resulting companies will be equal to or greater than what the value of our common stock would have been had the Separation not occurred.
In addition, following the completion of the Separation or any other disposition of our Flash business unit, we will not be able to rely on the earnings, assets or cash flow of the Flash business unit, and that business will not provide funds to finance our working capital or other cash requirements. As a result, our ability to service our debt may be adversely affected.
We cannot predict the prices at which our common stock may trade after the Separation or the effect of the Separation on the trading prices of our common stock.
The Separation will be subject to conditions including the availability of financing. We have not obtained any financing with respect to the Separation transaction, including any new financing for the remaining business and the terms of any such arrangements may be more burdensome or costly than the terms of our current indebtedness or we may not be able to obtain credit on attractive terms and price. Furthermore, any Separation may cause us to breach covenants in our existing indebtedness if such indebtedness is not repaid or refinanced or a waiver is not obtained prior to the Separation. For example, our credit facilities contain specific restrictions on any disposal of our Flash business unit. In addition, we cannot assure you that a holder of our outstanding senior notes will not argue that the Separation constitutes a change of control and try to require us to repurchase its notes as a result of the Separation.
