NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
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 hard disk drive and NAND flash technologies.
The Company’s broad portfolio of technology and products addresses 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 the Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the year ended June 28, 2024. In the opinion of management, all adjustments necessary to fairly state the Condensed Consolidated Financial Statements have been made. Such adjustments consist of items 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 28, 2024. 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 2025, which will end on June 27, 2025, and fiscal year 2024, which ended on June 28, 2024, 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: hard disk drives (“HDD”) and Flash-based products (“Flash”).
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.
Business Separation Costs
On October 30, 2023, the Company announced that its Board of Directors had completed its strategic review of the business and, after evaluating a comprehensive range of alternatives, authorized the Company to pursue a plan to separate its HDD and Flash business units to create two independent, public companies. As a result of the plan, the Company has incurred separation and transition costs and expects to incur such costs through the completion of the separation of the businesses. The separation and transition costs are recorded within Business separation costs in the Condensed Consolidated Statements of Operations.
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. 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 (“FASB”) 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. As required by the ASU, the Company began to provide disclosure of outstanding obligations to such suppliers for all balance sheet dates presented beginning with the Company’s first quarter of 2024. The ASU also requires the Company to provide certain annual rollforward information related to those obligations, which will be required beginning with the Company’s financial statements for the year ending June 27, 2025. The Company will provide this disclosure in its Annual Report on Form 10-K for the year ended June 27, 2025. The ASU does not affect the recognition, measurement, or financial statement presentation of supplier finance program obligations. See Note 15, Supplier Finance Program, of the Notes to the Condensed Consolidated Financial Statements for information regarding the supplier finance program.
Recently Issued Accounting Pronouncements Not Yet Adopted
In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”, which expands on segment reporting requirements primarily through enhanced disclosures surrounding significant segment expenses. The ASU expands on existing segment reporting requirements to require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's CODM, a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. These incremental disclosures will be required beginning with the Company’s financial statements for the year ending June 27, 2025. The Company expects to provide any required disclosures at that time.
In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. The ASU calls for enhanced income tax disclosure requirements surrounding the tabular rate reconciliation and income taxes paid. The Company is currently compiling the information required for these disclosures. These incremental disclosures will be required beginning with the Company’s financial statements for the year ending June 26, 2026, with early adoption permitted. The Company expects to provide any required disclosures at that time.

Other intangible assets, net
As part of prior acquisitions, the Company recorded at the time of the acquisition acquired in-process research and development (“IPR&D”) for projects in progress that had not yet reached technological feasibility. 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 September 27, 2024 and June 28, 2024, IPR&D included in intangible assets, net was $72 million. During the three months ended September 27, 2024 and September 29, 2023, the Company did not record any impairment charges related to IPR&D.

Sale of a Majority Interest in a Subsidiary
In March 2024, the Company’s wholly-owned subsidiary, SanDisk China Limited (“SanDisk China”) entered into an equity purchase agreement to sell 80% of its equity interest in SanDisk Semiconductor (Shanghai) Co. Ltd. (“SDSS”), the Company’s indirect wholly-owned subsidiary in its Flash business, to JCET Management Co., Ltd. (“JCET”), a wholly-owned subsidiary of JCET Group Co., Ltd., a Chinese publicly listed company, thereby forming a venture between SanDisk China and JCET (the “Transaction”). Subsequent to the first quarter of fiscal 2025, on September 28, 2024, the Transaction closed. Proceeds from the sale, subject to certain working capital adjustments and payment of withholding taxes, are expected to be approximately $624 million. F ollowing the closing of the Transaction, SanDisk China’s remaining 20% ownership interest in the venture will be reported as an equity method investment.

Because the divestiture of SDSS does not represent a strategic shift that would have a major effect on the Company’s operations or financial results, it is not reported as discontinued operations. Instead, the assets and liabilities of SDSS subject to the Transaction as listed below have been reclassified to held for sale as of September 27, 2024, and will be derecognized in the second quarter of fiscal 2025 in connection with the closing of the Transaction.

(1) Goodwill was preliminarily allocated to SDSS based on the indicated fair value of the SDSS business relative to the total estimated fair value of the Flash business unit. This preliminary allocation of goodwill may be revised based on finalization of working capital adjustments and valuations of SDSS and the Flash business unit in connection with the derecognition of SDSS during the second quarter of fiscal 2025.
(2) An intercompany account receivable and intercompany account payable totaling $110 million between SDSS and another subsidiary of the Company are eliminated in the Company’s Condensed Consolidated Financial Statements and have been excluded from the assets reclassified to held for sale. The intercompany account receivable was sold as part of the Transaction, and thus will be considered when determining the expected gain to be recognized upon the derecognition of SDSS. As a result, during the second quarter of fiscal 2025, the Company will reclassify this intercompany account payable to the applicable liability line item in the Condensed Consolidated Balance Sheets as it will represent a liability to an external third party.

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 instruments that were measured at fair value on a recurring basis for the periods presented, and indicate the fair value hierarchy of the valuation techniques utilized to determine such values:

Note 6. Derivative Instruments and Hedging Activities
As of September 27, 2024, the Company had outstanding foreign exchange forward contracts that were designated as either cash flow hedges or non-designated hedges. Substantially all of the contract maturity dates of these foreign exchange forward contracts do not exceed 12 months. As of September 27, 2024, the Company did not have any derivative contracts with credit-risk-related contingent features.
Changes in fair values of the non-designated foreign exchange contracts were recognized in Other income (expense), net and were largely offset by corresponding changes in the fair values of the foreign currency-denominated monetary assets and liabilities. For each of the three months ended September 27, 2024 and September 29, 2023, total net realized and unrealized transaction and foreign exchange contract currency gains and losses were not material to the Company’s Condensed Consolidated Financial Statements.
Unrealized gains or losses on designated cash flow hedges were recognized in AOCL. For more information regarding cash flow hedges, see Note 4, Supplemental Financial Statement Data – Accumulated other comprehensive loss.
Netting Arrangements
Under certain provisions and conditions within agreements with counterparties to the Company’s foreign exchange forward contracts, subject to applicable requirements, the Company has the right of offset associated with the Company’s foreign exchange forward contracts and is allowed to net settle transactions of the same currency with a single net amount payable by one party to the other. As of September 27, 2024 and June 28, 2024, the effect of rights of offset was not material and the Company did not offset or net the fair value amounts of derivative instruments in its Condensed Consolidated Balance Sheets.

Long-term debt | $ | 5,650 |  |  | $ | 5,684 |

During the three months ended September 27, 2024, the Company made scheduled repayments of the Term Loan A-2 maturing in January 2027 (the “Term Loan A-2”) of $38 million. The Term Loan A-2 Loan bears interest, at the Company’s option, at a per annum rate equal to either (x) the Adjusted Term SOFR (as defined in the loan agreement governing the Term Loan A-2) plus an applicable margin varying from 1.125% to 2.000% or (y) a base rate plus an applicable margin varying from 0.125% to 1.000%, in each case depending on the corporate family ratings of the Company from at least two of the Credit Rating Agencies, with an initial interest rate of Adjusted Term SOFR plus 1.500%. The all-in interest rate for Term Loan A-2 as of September 27, 2024 was 6.696%.
During the three months ended September 27, 2024, the Company drew and repaid $150 million principal amount under its $2.25 billion revolving credit facility maturing in January 2027 (the “2027 Revolving Credit Facility”).
The Company had issued an outstanding standby letters of credit of $52 million as of September 27, 2024, which reduced the Company’s 2027 Revolving Credit Facility’s capacity by the same amount to $2.20 billion as of that date.
The loan agreements governing the Company’s 2027 Revolving Credit Facility and Term Loan A-2 require the Company to comply with certain financial covenants, consisting of a leverage ratio and a minimum liquidity requirement. As of September 27, 2024, the Company was in compliance with these financial covenants.
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 convertible at the option of any holder at an initial conversion price of approximately $52.20 per share of common stock beginning August 15, 2028. Prior to that date, if the trading price of the Company’s common stock remains above 130% of the conversion price for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading-day period prior to the end of a quarter, holders of the 2028 Convertible Notes would have the right to convert the 2028 Convertible Notes during the next succeeding calendar quarter. The 2028 Convertible Notes are also convertible prior to that date upon the occurrence of certain corporate events. Upon any conversion of the 2028 Convertible Notes, the Company will pay cash for 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.

During the calendar quarter ended June 30, 2024, the sale price conditional conversion feature of the notes mentioned above was triggered. As a result, the holder of the 2028 Convertible Notes had the right to convert the 2028 Convertible Notes during the calendar quarter ended September 30, 2024. Consequently, the Company classified the 2028 Convertible Notes in the Current portion of long-term debt in the Condensed Consolidated Financial Statements as of September 27, 2024. During the calendar quarter ended September 30, 2024, the sale price conditional conversion feature of the notes mentioned above was not triggered. As a result, the 2028 Convertible Notes are not convertible from October 1, 2024 through December 31, 2024. The Company will re-evaluate in each subsequent calendar quarter to determine if the 2028 Convertible Notes have become convertible.
In connection with the issuance of the 2028 Convertible Notes, the Company also entered into privately negotiated capped call transactions with certain counterparties (the “Capped Calls”). The Capped Calls each have a strike price of approximately $52.20 per share, subject to certain adjustments, which correspond to the initial conversion price of the 2028 Convertible Notes. The Capped Calls have initial cap prices of $70.26 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, approximately 8 million shares of the Company’s common stock. The Capped Calls are generally intended to reduce or offset the potential dilution to the Company’s common stock upon any conversion of the 2028 Convertible Notes with such reduction or offset, as the case may be, subject to a cap based on the cap price. However, if the market price per share of the Company’s common stock, as measured under the terms of the Capped Calls, exceeds the cap prices of the Capped Calls, there would not be an offset for the excess. The Capped Calls are separate transactions, and not part of the terms of the 2028 Convertible Notes. As these transactions meet certain accounting criteria, the Capped Calls are recorded in stockholders’ equity and are not accounted for as derivatives.

During the three months ended September 27, 2024 and September 29, 2023, the Company made net payments to Flash Ventures of $889 million and $939 million, 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 27, 2024 and June 28, 2024, the Company had accounts payable balances due to Flash Ventures of $352 million and $313 million, respectively.
The Company’s maximum reasonably estimable loss exposure (excluding lost profits) as a result of its involvement with Flash Venture s, based upon the Japanese yen to U.S. dollar exchange rate at September 27, 2024, is pres ented 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 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 27, 2024.
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, a wafer fabrication facility in Yokkaichi, Japan, referred to as “Y7”, and a wafer fabrication facility in Kitakami, Japan, referred to as “K2”. In connection with the start-up of these facilities, the Company has made prepayments toward future building depreciation. In connection with the start-up of the K1, K2 and Y7 facilities, the Company has made prepayments over time, and as of September 27, 2024, $722 million remains to be credited against future building depreciation charges. As of September 27, 2024, the Company is also committed to make additional building depreciation prepayments of $605 million, based on the Japanese yen to U.S. dollars exchange rate of 142.56 as of such date, payable as follows: $337 million for the remainder of fiscal year 2025, $33 million in fiscal year 2026, $123 million in fiscal year 2027, $98 million in fiscal year 2028 and $14 million in fiscal year 2029. As of September 27, 2024, in addition to the requirements to make building depreciation prepayments, the Company will also make payments for building depreciation of approximately $315 million at varying dates through fiscal year 2035.
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 27, 2024.

Leases
The Company leases certain domestic and international facilities and data center space under long-term, non-cancelable operating leases that expire at various dates through 2039. These leases include no material variable or contingent lease payments. Operating lease assets and liabilities are recognized based on the present value of the remaining lease payments discounted using the Company’s incremental borrowing rate. Operating lease assets also include prepaid lease payments minus any lease incentives.

RSUs and PSUs outstanding at September 27, 2024 | 13.5 |  |  | $ | 51.20 |  |  |

RSUs and PSUs are generally settled in an equal number of shares of the Company’s common stock at the time of vesting of the units.
Convertible Preferred Stock
On January 31, 2023, the Board of Directors of the Company authorized the designation of 900,000 shares of Series A Convertible Perpetual Preferred Stock, par value $0.01 per share (the “Preferred Shares”), from the Company’s existing five million authorized but unissued shares of preferred stock and issued the Preferred Shares through a private placement. As of September 27, 2024 and June 28, 2024, 235,000 of the Preferred Shares were outstanding.
The Preferred Shares have a stated value of $1,000 per share and accrue a cumulative preferred dividend at an annual rate of 6.25% per annum (increasing to 7.25% per annum on January 31, 2030 and to 8.25% per annum on January 31, 2033) compounded on a quarterly basis. The Preferred Shares also participate in any dividends declared for common shareholders on an as-converted equivalent basis. No dividends have been declared or paid since the issuance of the Preferred Shares. As of September 27, 2024 and June 28, 2024, unpaid and cumulative dividends payable with respect to the Preferred Shares were $26 million and $22 million, respectively.
The Preferred Shares are convertible into shares of the Company’s common stock at an initial conversion rate of $47.75 per share (the “Conversion Price”) (subject to anti-dilution adjustments and certain other one-time adjustments upon the occurrence of various specified spin-off transactions) applied to the aggregate sum of the stated value of the Preferred Shares plus any cumulative accrued but unpaid dividends (the “Accumulated Stated Value”). In the event of a standalone spin-off transaction, the holders of the Preferred Shares may have one third of their Preferred Shares converted to a similar class of preferred shares of the spin-off entity. The Preferred Shares will be convertible at the option of the Company after January 31, 2026 if the closing price per share of the Company’s common stock exceeds 150% of the Conversion Price for at least 20 out of 30 consecutive trading days immediately prior to the Company’s conversion notice.
As of September 27, 2024 and June 28, 2024, the Preferred Shares outstanding had an aggregate liquidation preference of $261 million and $257 million, respectively, and would have been convertible, if otherwise permitted, into approximately 5 million shares of common stock on each such date.

Note 12. Income Tax Expense
Beginning in fiscal year 2023, the Tax Cuts and Jobs Act (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 27, 2024 and September 29, 2023.
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 CAMT was effective for the Company beginning with fiscal year 2024. The Company does not expect to be subject to CAMT for fiscal year 2025 as its average annual AFSI did not exceed $1.0 billion for the preceding three-year period.
On December 20, 2021, the Organization for Economic Co-operation and Development G20 (“OECD/G20”) Inclusive Framework on Base Erosion and Profit Shifting released Model Global Anti-Base Erosion rules under Pillar Two (“Pillar Two Model Rules”). Several non-US jurisdictions have either enacted legislation or announced their intention to enact future legislation to adopt certain or all components of the Pillar Two, some which are effective for the Company in fiscal year 2025. For fiscal year 2025, the Company currently expects to be able to meet certain transitional safe harbors and does not expect any material Pillar Two taxes. As more jurisdictions adopt this legislation in fiscal year 2026, there may be material increases in the Company’s future tax obligations in certain jurisdictions.
The following table presents the Company’s Income tax expense and the effective tax rate:

| Three Months Ended |  |
| September 27, 2024 |  | September 29, 2023 |  |  |  |
| ($ in millions)
Income (loss) before taxes | $ | 628 |  | $ | (682) |  |  |  |
Income tax expense | 135 |  | 3 |  |  |  |
Effective tax rate | 21 | % |  | — | % |  |  |  |

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 have or will expire at various dates during years 2025 through 2031 resulted in decreases to the effective tax rate below the U.S. statutory rate for the three months ended September 27, 2024. However, the tax effects of the mandatory capitalization of R&D expenses offset these decreases, resulting in the effective tax rate being closer to the U.S. Federal statutory rate for the three months ended September 27, 2024.
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.
Uncertain Tax Positions
With the exception of certain unrecognized tax benefits that are directly associated with the tax position taken, unrecognized tax benefits are presented gross in the Condensed Consolidated Balance Sheets.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits excluding accrued interest and penalties for the three months ended September 27, 2024 (in millions):

Accrual balance at June 28, 2024 | $ | 721 |
Gross increases related to current year tax positions | 4 |
Gross increases related to prior year tax positions | 9 |
Gross decreases related to prior year tax positions | (2) |
Settlements | (39) |
Lapse of statute of limitations | (1) |
Accrual balance at September 27, 2024 | $ | 692 |

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 27, 2024 were $70 million. Of the aggregate unrecognized tax benefits, including interest and penalties, as of September 27, 2024, approximately $597 million could result in potential cash payments. The Company is not able to provide a reasonable estimate of the timing of future tax payments related to these obligations.
The Company had previously reached a final agreement with the IRS regarding notices of deficiency with respect to years 2008 through 2012 and in February 2024, also reached a final agreement for resolving the notices of proposed adjustments with respect to years 2013 through 2015. During the three months ended September 27, 2024, the Company made a payment of $130 million for interest with respect to years 2008 through 2012 and $23 million for tax and interest with respects to years 2013 through 2015, resulting in a remaining liability of $10 million as of September 27, 2024 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, 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 $162 million. Of this amount, $31 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 27, 2024, 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 27, 2024 |  |  | September 29, 2023 |  |  |  |
| (in millions, except per share data)
Net income (loss) | $ | 493 |  |  |  | $ | (685) |  |  |  |  |
Less: dividends allocated to preferred shareholders | 4 |  |  |  | 15 |  |  |  |  |

Net income (loss) attributable to common stockholders | $ | 481 |  |  |  | $ | (700) |  |  |  |  |
Weighted average shares outstanding: |  |  |  |  |  |  |  |
Basic | 344 |  |  |  | 323 |  |  |  |  |
RSUs, PSUs, ESPP, and the convertible notes | 13 |  |  |  | — |  |  |  |  |
Diluted | 357 |  |  |  | 323 |  |  |  |  |
Net income (loss) per common share |  |  |  |  |  |  |  |
Basic | $ | 1.40 |  |  |  | $ | (2.17) |  |  |  |  |
Diluted | $ | 1.35 |  |  |  | $ | (2.17) |  |  |  |  |
Anti-dilutive potential common shares excluded | — |  |  |  | 15 |  |  |  |  |

(1) Preferred stock represents participating securities because they participate in any dividends on shares of common stock on a pari passu, pro rata basis. Preferred stock does not participate in undistributed net losses.
Basic net income (loss) per share attributable to common shareholders is computed using (i) net income (loss) less (ii) dividends allocated to preferred shareholders 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 convertible notes and the preferred shares. The treasury stock method is used to determine the dilutive impact of unvested equity awards.
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 Company’s convertible notes, and the preferred shares. For the three months ended September 27, 2024, all common shares subject to outstanding equity awards are included in the calculation of diluted shares based on the Company’s average stock price during the period. 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.

Note 14. Employee Termination, Asset Impairment, and Other
Business Realignment
The Company periodically incurs charges 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. The Company may also record credits related to gains upon sale of property in connection with these activities. In this regard, for the three months ended September 29, 2023, the Company reassessed existing capacity development plans and made a decision to cancel certain projects, including projects to expand capacity in its Penang, Malaysia facility, resulting in the impairment of existing construction in progress, other assets and the recognition of a liability for certain contract termination costs. The Company also took 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 presented:

| Three Months Ended |  |  |  |
| September 27, 2024 |  | September 29, 2023 |  |  |  |  |  |

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 $41 million and $37 million as of September 27, 2024 and June 28, 2024, respectively, and are included within Accounts payable on the Company’s Condensed Consolidated Balance Sheets.

Intellectual Property Litigation
On August 26, 2022, MR Technologies, GmbH (“MRT”) filed an action in the United States District Court for the Central District of California (the “Central District Court”) against the Company’s wholly-owned subsidiary, Western Digital Technologies, Inc., alleging infringement of U.S. Patent Nos. 9,978,413, 9,928,864, 11,133,031 and 11,138,997, each of which relate to hard disk drive media. As the case progressed, MRT dropped its claims with respect to U.S Patent Nos. 9,978,413 and 11,133,031, and the case proceeded to trial in July 2024 on the remaining two patents (together, the “MRT Patents”). The trial concluded on July 26, 2024, and the jury awarded MRT a lump sum of $262 million for use of the MRT Patents in the past and through their remaining lives. MRT also requested and was awarded prejudgment interest totaling $117 million in a judgment entered on August 15, 2024. In addition, MRT requested attorney’s fees and post-judgment interest.
In the fourth quarter of fiscal 2024, the Company recognized an aggregate liability for this matter of $384 million with $291 million recognized as an Operating expense under Litigation matter for the year ended June 28, 2024 and $93 million recognized as Other non-current assets for the patent licenses, to be amortized over their remaining lives. During the first quarter of fiscal 2025, the Company recognized incremental charges of $3 million related to plaintiff’s attorney’s fees in Operating expense under Litigation matter, $2 million of post-judgment interest in Other income (expense), net, and $9 million in Cost of revenue from the subsequent amortization of licenses related to this matter. The Company believes it has meritorious defenses, plans to file post-trial motions, and if not successful, plans to appeal the judgment and continue to defend itself vigorously.
On September 28, 2016, SPEX Technologies, Inc. (“SPEX”) filed a lawsuit in the Central District Court against the Company and two of the Company’s current or former wholly-owned subsidiaries, Western Digital Technologies, Inc. and HGST Inc., alleging infringement of U.S. Patent Nos. 6,088,802 and 6,003,135, both of which allegedly relate to moving a security mechanism (e.g., the encrypting/decrypting mechanism) from a host computer or a separate device to a peripheral device that provides data storage. As the case progressed, SPEX dismissed its allegations relating to U.S. Patent No. 6,003,135 and narrowed its case to one claim under U.S. Patent No. 6,088,802 asserted against certain HDD products that may include certain encryption capabilities. The trial commenced on October 8, 2024, concluded on October 18, 2024, and the jury awarded SPEX damages of $316 million for the use of one claim of U.S. Patent No. 6,088,802 in the past, prior to its expiration in 2017. SPEX has also requested the court to award it prejudgment interest of $233 million and legal costs. The Company intends to contest the verdict and, based on available arguments, the Company believes the jury verdict and any prejudgment interest and legal costs will be reversed, amended or vacated when the Company files motions for judgment as a matter of law in the district court or presents its appeal to the United States Court of Appeals for the Federal Circuit, if necessary. The Company therefore, believes a loss is not probable and has not accrued a liability as a result of the jury verdict or the request for prejudgment interest and legal costs in its financial statements as of September 27, 2024.
The ability to predict the ultimate outcome of these matters involves judgments, estimates and inherent uncertainties. The actual outcome of these matters could differ materially from management’s estimates.
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 management’s expectations.

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 28, 2024. 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 a leading developer, manufacturer, and provider of data storage devices based on both hard disk drive and NAND flash technologies. With a differentiated innovation engine driving advancements in storage and semiconductor technologies, our broad and ever-expanding portfolio delivers powerful HDD and Flash 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 addresses our multiple end markets: “Cloud,” “Client,” and “Consumer”. Cloud is comprised primarily of products for public or private cloud environments and enterprise customers. Through the Client end market, we provide our original equipment manufacturer “OEM” and channel customers a broad array of high-performance HDD and Flash 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 2025, which will end on June 27, 2025, and fiscal year 2024, which ended on June 28, 2024, 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. At the beginning of our second quarter of fiscal 2025, we entered the soft-spin phase of our separation plan. The soft-spin phase represents the period when we begin testing critical processes and systems for each future HDD and Flash company to ensure that both are ready to operate independently at legal separation. We continue to make progress on the work required to execute the separation, which we expect will occur after we close the second quarter of fiscal 2025.
Operational Update
Macroeconomic factors such as inflation, changes in interest rates, and recession concerns softened demand for our products during 2023 and the first half of 2024. As a result, we and our industry experienced a supply-demand imbalance, which resulted in reduced shipments and negatively impacted pricing during those periods. To adapt to these conditions, since the beginning of 2023, we implemented measures to reduce operating expenses and proactively manage supply and inventory to align with demand and improve our capital efficiency while continuing to deploy innovative products. These actions enabled us to scale back on capital expenditures, consolidate production lines, and reduce production. During the first quarter of 2024, these actions resulted in incremental charges for employee termination, asset impairment, and charges for unabsorbed manufacturing overhead costs in HDD and Flash due to the underutilization of facilities as we temporarily scaled back production.
39

Table of Contents
We are now seeing an improvement in the supply and demand dynamic, leading to improved revenues. The increase in demand resulted in increased revenue and gross margin across our segments in the first quarter of 2025 from the comparable period in the prior year. We anticipate that digital transformation, including the AI data-cycle, will continue to drive improved market conditions in the near- and long-term for data storage, encompassing HDD and Flash technologies. Leveraging our expertise and innovation in both areas, we believe we are well-positioned to capitalize on this improved market condition.
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.
Sale of a Majority Interest in a Subsidiary
As discussed in Part I, Item 1, Note 4, Supplemental Financial Statement Data, of the Notes to Condensed Consolidated Financial Statements, in March 2024, we entered into an agreement to sell 80% of the equity interest in one of our Flash manufacturing subsidiaries to JCET, a third-party contract manufacturing company. Subsequent to the first quarter of fiscal 2025, on September 28, 2024, the transaction closed. In connection with this transaction, we entered into a 5-year supply agreement with JCET to purchase wafers with a minimum annual commitment of $550 million.
As a result of this transaction, we expect to incur a modest reduction in annual operating expenses and a reduction in annual capital expenditures related to assembly and testing of Flash-based products. We also anticipate that the transition to a contract manufacturing model through SDSS will result in a small increase in our annual cost of revenue for Flash-based products.
Tax Resolution
As previously disclosed, we had previously reached a final agreement with the IRS and received notices of deficiency with respect to years 2008 through 2012 and in February 2024, also reached a final agreement for resolving the notices of proposed adjustments with respect to years 2013 through 2015. During the three months ended September 27, 2024, we made payments aggregating $153 million for tax and interest with respect to all years 2008 through 2015 and have a remaining liability of $10 million as of September 27, 2024 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 Condensed Consolidated Financial Statements, and in the “Short- and Long-term Liquidity – Unrecognized Tax Benefits” section below.

Net Revenue
Comparison of Three Months Ended September 27, 2024 to Three Months Ended September 29, 2023
The increase in consolidated net revenue for the three months ended September 27, 2024 from the comparable period in the prior year reflected increases in both HDD and Flash revenue as discussed in more detail below.
HDD revenue increased by 85% for the three months ended September 27, 2024 from the comparable period in the prior year, as a result of a 107% increase in exabytes sold, primarily from higher shipments of our high capacity enterprise drives, partially offset by a 10% decline in average selling prices per gigabyte primarily due to a shift in the product mix to larger capacity drives.
42

Table of Contents
Flash revenue increased by 21% for the three months ended September 27, 2024 from the comparable period in the prior year, reflecting a 39% increase in average selling prices per gigabyte primarily due to improved pricing as the supply-demand balance improved, partially offset by a 12% decrease in exabytes sold. The decrease in exabytes sold was primarily due to the near-term drop in demand in the Client and Consumer end markets, partially offset by increased demand in the Cloud end market.
Cloud revenue increased by 153% for the three months ended September 27, 2024 from the comparable period in the prior year, reflecting a 140% increase in exabytes sold and a 7% increase in average selling prices per gigabyte. The increase in exabytes sold was driven by higher shipments of our high capacity enterprise HDD products stemming from new data center builds. The increase in average selling prices per gigabyte was primarily due to improved pricing in Flash as the supply-demand balance improved.
Client revenue increased by 5% for the three months ended September 27, 2024 from the comparable period in the prior year, reflecting a 33% increase in average selling prices per gigabyte, partially offset by a 20% decrease in exabytes sold. The increase in average selling prices per gigabyte over the prior year period was primarily due to improved pricing in Flash. The decline in exabytes sold reflected the near-term drop in demand for Flash products.
Consumer revenue declined 7% for the three months ended September 27, 2024 from the comparable period in the prior year, reflecting a 15% decrease in exabytes sold, partially offset by a 10% increase in average selling prices per gigabyte. The decrease in exabytes sold was due to lower shipments of both HDD and Flash products. The increase in average selling prices per gigabyte was driven by improved pricing in both HDD and Flash .
The changes in net revenue by geography for the three months ended September 27, 2024 from the comparable period in the prior year reflected higher revenue in the Americas region from Cloud customers as noted above.
Our top 10 customers accounted for 51% of our net revenue for the three months ended September 27, 2024, compared to 44% of our net revenue for the three months ended September 29, 2023. For the three months ended September 27, 2024, one customer accounted for 14% of our net revenue. No customer accounted for 10% or more of the Company’s net revenue for the three months ended September 29, 2023.
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 13% and 20% of gross revenue for the three months ended September 27, 2024 and September 29, 2023, respectively. 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. The decrease in program amounts in the current period reflects the improved demand and pricing environment. 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 increased by $1.45 billion for the three months ended September 27, 2024 from the comparable period in the prior year, primarily due to higher product shipments, improved pricing, and favorable product mix. In addition, the prior year period included charges for unabsorbed manufacturing overhead costs as a result of the reduced utilization of our manufacturing capacity of $225 million ($83 million in HDD and $142 million in Flash), which were not incurred in the current period. Consolidated gross margin increased by 34 percentage points year over year, mainly due to improved pricing and favorable product mix with approximately 8 percentage points of the increase due to the underutilization charges incurred in the prior year period but not incurred in the current period.
HDD gross margin increased by 15 percentage points year over year, primarily due to higher product shipments with approximately 7 percentage points of the increase due to the manufacturing underutilization charges incurred in the prior year period but not incurred in the current period.
Flash gross margin increased by 49 percentage points year over year, primarily due to improved pricing and favorable product mix with approximately 9 percentage points of the increase due to the underutilization charges incurred in the prior year period but not incurred in the current period.

Operating Expenses
Research and development (“R&D”) expense increased by $88 million for the three months ended September 27, 2024 from the comparable period in the prior year. The increase was driven by a $56 million increase in compensation and benefits due to higher variable compensation and increased headcount, a $10 million increase in material purchases, and modest increases in spending for R&D projects as we continue to invest in innovation.
Selling, general and administrative (“SG&A”) expense increased by $35 million for the three months ended September 27, 2024 from the comparable period in the prior year. The increase was primarily driven by a $26 million increase in compensation and benefits due to higher variable compensation and increased headcount, a $10 million increase in legal fees, and an $8 million increase in dis-synergy costs as we prepare for the business separation, partially offset by a $17 million decrease in strategic review costs.
Employee termination, asset impairment and other charges decreased by $55 million for the three months ended September 27, 2024 from the comparable period in the prior year, reflecting fewer restructuring actions taken in the current period. 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.
Business separation costs were $43 million for the three months ended September 27, 2024, primarily reflecting outside service fees to support the planned separation of our HDD and Flash businesses.
Interest and Other Expense
Total interest and other expense, net increased by $28 million for the three months ended September 27, 2024 from the comparable period in the prior year, reflecting an increase in other expense, net of $28 million, driven by a loss on our equity investments.
Income Tax Expense
Beginning in 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 our effective tax rate for the three months ended September 27, 2024 and September 29, 2023. The tax effects related to the capitalization of R&D expenses had a material impact on our effective tax rate for the three months ended September 27, 2024 but did not have a material impact on the effective tax rate for the three months ended September 29, 2023.
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 do not expect to be subject to the CAMT of 15% for fiscal year 2025 as our annual average AFSI did not exceed $1.0 billion for the preceding three-year period.
On December 20, 2021, the Organization for Economic Co-operation and Development G20 (“OECD/G20”) Inclusive Framework on Base Erosion and Profit Shifting released Model Global Anti-Base Erosion rules under Pillar Two. Several non-US jurisdictions have either enacted legislation or announced their intention to enact future legislation to adopt certain or all components of the Pillar Two, some which are effective for us in fiscal year 2025. For fiscal year 2025, we currently expect to be able to meet certain transitional safe harbors and do not expect any material Pillar Two taxes. As more jurisdictions adopt this legislation in fiscal year 2026, there may be material increases in our future tax obligations in certain jurisdictions.

The following table sets forth Income tax information from our Condensed Consolidated Statements of Operations by dollar and effective tax rate:

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 have or will expire at various dates during years 2025 through 2031 resulted in decreases to our effective tax rate below the U.S. Federal statutory rate three months ended September 27, 2024. However, the tax effects of the mandatory capitalization of R&D expenses offset these decreases, resulting in our effective tax rate being closer to the U.S. Federal statutory rate for the three months ended September 27, 2024.
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% 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 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.

We had previously reached a final agreement with the IRS and received notices of deficiency with respect to years 2008 through 2012 and in February 2024, also reached a final agreement for resolving the notices of proposed adjustments with respect to years 2013 through 2015. During the three months ended September 27, 2024, the Company made payments of $130 million for interest with respect to years 2008 through 2012 and $23 million for tax and interest with respect to years 2013 through 2015, resulting in a remaining liability of $10 million as of September 27, 2024, 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 $162 million. Of this amount, $31 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.
In August 2024, we filed a shelf registration statement (the “Shelf Registration Statement”) with the Securities and Exchange Commission that expires in August 2027. The Shelf Registration Statement 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.
In 2024, we reduced our expenditures for property, plant and equipment and our portion of the Flash Ventures’ capital expenditures for its operations to approximately $825 million from approximately $2.22 billion in 2023. 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 $53 million in 2024 from $794 million in 2023. We continue to be disciplined with our capital investments and expect our cash capital expenditures in 2025 to be higher than in 2024, but remain below 2023 expenditures.
We believe our cash and cash equivalents 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. 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 28, 2024.
A total of $1.43 billion of our Cash and cash equivalents was held by our foreign subsidiaries as of September 27, 2024 and June 28, 2024, respectively. There are no material tax consequences that were not previously accrued for on the repatriation of this cash.
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 $753 million for the three months ended September 27, 2024, as compared to $132 million for the three months ended September 29, 2023, which largely reflects an increase in the volume of our business, 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 the 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 27, 2024 |  | September 29, 2023 |  |  |  |
Days sales outstanding | 55 |  |  | 48 |  |  |  |  |
Days in inventory | 121 |  |  | 120 |  |  |  |  |
Days payable outstanding | (69) |  |  | (54) |  |  |  |  |
Cash conversion cycle | 107 |  |  | 114 |  |  |  |  |

Changes in days sales outstanding (“DSO”) are generally due to the timing of shipments to and collections from customers. Changes in days in inventory (“DIO”) are generally related to the timing of inventory builds and shipments to customers. Changes in days payables outstanding (“DPO”) are generally related to production volume and the timing of purchases during the period. From time to time, we make payment term modifications with vendors through negotiations with them or by granting to, or receiving from, our vendors payment term accommodations. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances.
For the three months ended September 27, 2024, DSO increased by 7 days from the comparable period in the prior year, of which 5 days reflected an increase from lower trade accounts receivable factoring and the remainder reflected the timing of shipments and customer collections. DIO increased by 1 day from the comparable period in the prior year, primarily reflecting higher production volume in the current period. DPO increased by 15 days from the comparable period in the prior year primarily due to more favorable payment terms and routine variations in the timing of purchases and payments during the period.
Investing Activities
Net cash used in investing activities for the three months ended September 27, 2024 primarily consisted of $96 million in capital expenditures, partially offset by $47 million in net proceeds from activity related to Flash Ventures. Net cash provided by investing activities for the three months ended September 29, 2023 primarily consisted of $193 million in proceeds from disposals of assets, which includes the proceeds from our sale-leaseback of our Milpitas, California facility and $13 million in net proceeds from activity related to Flash Ventures, partially offset by $124 million in capital expenditures.
Financing Activities
During the three months ended September 27, 2024, net cash used in financing activities primarily consisted of $188 million for repayment of amounts borrowed under the revolving credit facility and scheduled repayments on the Term Loan A-2, and $64 million for taxes paid on vested stock awards under employee stock plans, partially offset by $150 million of proceeds from drawing on the revolving credit facility. During the three months ended September 29, 2023, net cash provided by financing activities primarily consisted of $600 million of proceeds from the drawdown of our delayed draw term loan, partially offset by $43 million used for taxes paid on vested stock awards under employee stock plans.

(1)Principal portion of debt, excluding 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.
Unrecognized Tax Benefits
As of September 27, 2024, the liability for unrecognized tax benefits (excluding accrued interest and penalties) was $692 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 27, 2024 was $70 million. Of these amounts, approximately $597 million could result in potential cash payments. As of September 27, 2024, 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 our liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of our tax returns.
As noted above, we had previously reached a final agreement with the IRS regarding notices of deficiency with respect to years 2008 through 2012 and in February 2024, also reached a final agreement for resolving the notices of proposed adjustments with respect to years 2013 through 2015. During the three months ended September 27, 2024, we made payments of $130 million for interest with respect to years 2008 through 2012 and $23 million for tax and interest with respect to years 2013 through 2015, resulting in a remaining liability of $10 million as of September 27, 2024 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 $162 million. Of this amount, $31 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.

Litigation Matters
For additional information on the litigation matters, see Part I, Item 1, Note 16, Legal Proceedings, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.
Dividend rights
As of September 27, 2024, 235,000 shares of our Series A Preferred Stock remained outstanding. These shares are entitled to cumulative preferred dividends and will also participate in any dividends declared for common shareholders on an as-converted equivalent basis. See Part II, Item 8, Note 12, Shareholders’ Equity and Convertible Preferred Stock, of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended June 28, 2024 and 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
As described in Part I, Item 1, Note 7, Debt, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q, the Company issued $1.60 billion aggregate principal amount of convertible senior notes in November 2023, which bear interest at an annual rate of 3.00% and mature on November 15, 2028 (the “2028 Convertible Note”). The 2028 Convertible Notes are convertible at the option of any holder at an initial conversion price of approximately $52.20 per share of common stock beginning August 15, 2028. Prior to that date, if the trading price of our common stock remains above 130% of the conversion price for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading-day period prior to the end of a calendar quarter, holders of the 2028 Convertible Notes would have the right to convert the 2028 Convertible Notes during the next succeeding calendar quarter. The 2028 Convertible Notes are also convertible prior to that date upon the occurrence of certain corporate events. Upon any conversion of the 2028 Convertible Notes, we will pay cash for the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of our common stock or a combination thereof, at our election, in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the notes being converted.
During the calendar quarter ended June 30, 2024, the sale price conditional conversion feature of the notes mentioned above was triggered. As a result, the holder of the 2028 Convertible Notes had the right to convert the 2028 Convertible Notes during the calendar quarter ended September 30, 2024. Consequently, we classified the 2028 Convertible Notes in the Current portion of long-term debt in the Condensed Consolidated Financial Statements as of September 27, 2024. During the calendar quarter ended September 30, 2024, the sale price conditional conversion feature of the notes mentioned above was not triggered. As a result, the 2028 Convertible Notes are not convertible from October 1, 2024 through December 31, 2024. We will re-evaluate in each subsequent calendar quarter to determine if the 2028 Convertible Notes have become convertible.
In addition to our existing debt, as of September 27, 2024, we had $2.20 billion available for borrowing under our revolving credit facility until January 2027, subject to customary conditions under the loan agreement. 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 7, Debt, of the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended June 28, 2024 and Note 7, Debt, 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 and our Term Loan A-2 maturing 2027 require us to comply with certain financial covenants, consisting of a leverage ratio, and a minimum liquidity requirement. As of September 27, 2024, we were in compliance with these financial covenants.
We may issue additional debt securities in the future that may be guaranteed by our 100% owned domestic subsidiary, Western Digital Technologies, Inc. (“Guarantor” and, together with Western Digital Corporation, the “Obligor Group”). Such guarantees may be full and unconditional, joint and several, on a secured or unsecured, subordinated or unsubordinated basis, and may be subject to certain customary guarantor release conditions. We conduct operations almost entirely through our subsidiaries. Accordingly, the Obligor Group’s cash flow and ability to service any guaranteed registered debt securities will depend on the earnings of our subsidiaries and the distribution of those earnings to the Obligor Group, including the earnings of the non-guarantor subsidiaries, whether by dividends, loans or otherwise. Holders of such guaranteed registered debt securities would have a direct claim only against the Obligor Group.

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 27, 2024, 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.

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 year:

| September 27, 2024
| (in millions)
2026 | $ | 331 |

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 higher cash tax payments in future profitable 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.
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 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 28, 2024. Please refer to Part II, Item 7 of our Annual Report on Form 10‑K for the year ended June 28, 2024 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 27, 2024. 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 28, 2024 for further information about our exposure to market risk.
Foreign Currency Risk
We performed sensitivity analyses as of September 27, 2024, 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 27, 2024. 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 $294 million at September 27, 2024.
Interest Rate Risk
We have generally held a balance of fixed and variable rate debt. As of September 27, 2024, our variable rate debt outstanding consisted of our Term Loan A-2, which is 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 27, 2024, the outstanding balance on our variable rate debt was $2.6 billion and a one percent increase in the variable rate of interest would increase annual interest expense by $26 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 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
