End Market Summary

Revenue ($M)	Q2 2025		Q1 2025		Q/Q	Q2 2024		Y/Y
Cloud	$	2,346	$	2,208	up 6%	$	1,071	up 119%
Client		1,168		1,209	down 3%		1,122	up 4%
Consumer		771		678	up 14%		839	down 8%
Total Revenue	$	4,285	$	4,095	up 5%	$	3,032	up 41%

In the fiscal second quarter:

Cloud represented 55% of total revenue at $2.3 billion, up 6% sequentially and more than doubling year-over-year. On a sequential basis, the growth was due to an increase in nearline HDD shipments while Flash was down. On a year-over-year basis, both HDD and Flash revenue grew.
Client represented 27% of total revenue at $1.2 billion, down 3% sequentially and up 4% year-over-year. Compared to last quarter, Flash revenue declined as bit shipment growth was offset by pricing pressure, while HDD revenue was flat. Year-over-year, an increase in Flash revenue was primarily due to higher ASPs as bit shipments declined and was partially offset by lower HDD revenue.
Consumer represented 18% of total revenue at $0.8 billion, up 14% sequentially and down 8% year-over-year. Sequentially, both Flash and HDD bit shipments grew and drove revenue growth while pricing was a headwind. Year-over-year, the decrease was due to lower shipments in Flash and HDD and pricing in Flash.

_______________

⁽¹⁾		Non-GAAP gross margin guidance excludes stock-based compensation expense, amortization of acquired intangible assets and amortization of patent licenses related to a litigation matter, totaling approximately $20 million to $30 million. The company's Non-GAAP operating expenses guidance excludes stock-based compensation expense and expenses related to business separation costs, totaling approximately $80 million to $100 million. In the aggregate, Non-GAAP diluted earnings per share guidance excludes these items totaling $100 million to $130 million. The timing and amount of these charges excluded from Non-GAAP gross margin, Non-GAAP operating expenses, and Non-GAAP diluted earnings per share cannot be further allocated or quantified with certainty. Additionally, the timing and amount of additional charges the company excludes from its Non-GAAP tax rate and Non-GAAP diluted earnings per share are dependent on the timing and determination of certain actions and cannot be reasonably predicted. Accordingly, full reconciliations of Non-GAAP gross margin, Non-GAAP operating expenses, Non-GAAP tax rate and Non-GAAP diluted earnings per share to the most directly comparable GAAP financial measures (gross margin, operating expenses, tax rate and diluted earnings per share, respectively) are not available without unreasonable effort.
⁽²⁾		Non-GAAP tax rate is determined based on a percentage of Non-GAAP pre-tax income or loss. Our estimated Non-GAAP tax rate may differ from our GAAP tax rate (i) due to differences in the tax treatment of items excluded from our Non-GAAP net income or loss; (ii) due to the fact that our GAAP income tax expense or benefit recorded in any interim period is based on an estimated forecasted GAAP tax rate for the full year, excluding loss jurisdictions; and (iii) because our GAAP taxes recorded in any interim period are dependent on the timing and determination of certain GAAP operating expenses.

To supplement the condensed consolidated financial statements presented in accordance with U.S. generally accepted accounting principles ("GAAP"), the tables above set forth Non-GAAP gross profit; Non-GAAP gross margin; Non-GAAP operating expenses; Non-GAAP operating income and loss; Non-GAAP interest and other expense, net; Non-GAAP net income and loss; Non-GAAP diluted income and loss per common share and free cash flow ("Non-GAAP measures"). These Non-GAAP measures are not in accordance with, or an alternative for, measures prepared in accordance with GAAP and may be different from Non-GAAP measures used by other companies. The company believes the presentation of these Non-GAAP measures, when shown in conjunction with the corresponding GAAP measures, provides useful information to investors for measuring the company's earnings performance and comparing it against prior periods. Specifically, the company believes these Non-GAAP measures provide useful information to both management and investors as they exclude certain expenses, gains and losses that the company believes are not indicative of its core operating results or because they are consistent with the financial models and estimates published by many analysts who follow the company and its peers. As discussed further below, these Non-GAAP measures exclude, as applicable, gain on business divestiture; stock-based compensation expense; business separation costs; charges related to a litigation matter; employee termination, asset impairment and other; expenses related to our strategic review; amortization of acquired intangible assets; recovery from contamination incident; other adjustments; and income tax adjustments. The company believes these measures along with the related reconciliations to the GAAP measures provide additional detail and comparability for assessing the company's results. These Non-GAAP measures are some of the primary indicators management uses for assessing the company's performance and planning and forecasting future periods. These measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results.

As described above, the company excludes the following items from its Non-GAAP measures:

Gain on business divestiture. In connection with the company's strategic decision to outsource the manufacturing of certain components and assemblies in its flash-based products, on September 28, 2024, the company completed the sale of 80% of one of its Flash manufacturing subsidiaries. The transaction resulted in a discrete gain, which the company believes it is not indicative of the underlying performance of its business.

Stock-based compensation expense. Because of the variety of equity awards used by companies, the varying methodologies for determining stock-based compensation expense, the subjective assumptions involved in those determinations, and the volatility in valuations that can be driven by market conditions outside the company's control, the company believes excluding stock-based compensation expense enhances the ability of management and investors to understand and assess the underlying performance of its business over time and compare it against the company's peers, a majority of whom also exclude stock-based compensation expense from their Non-GAAP results.

Business separation costs. The company incurred expenses associated with the separation of its HDD and Flash business units to create two independent, public companies. The company believes these charges do not reflect the company's operating results and that they are not indicative of the underlying performance of its business.

Litigation matter. The company has recognized expenses related to a recent judgment in a patent litigation matter, which consisted of an award of damages, prejudgment interest, and estimated plaintiff legal costs. The company also recognized expenses in its cost of revenue related to the amortization of patent licenses that the company has capitalized related to this litigation matter. The company believes these charges do not reflect the company's operating results and that they are not indicative of the underlying performance of its business. For further information regarding the litigation matter, see Note 17 to the notes to consolidated financial statements included in the company's Annual Report on Form 10-K filed with the SEC on August 20, 2024.

Employee termination, asset impairment and other. From time to time, in order to realign the company's operations with anticipated market demand or to achieve cost synergies from the integration of acquisitions, the company may terminate employees and/or restructure its operations. From time to time, the company may also incur charges from the impairment of intangible assets and other long-lived assets. In addition, the company may record credits related to gains upon sale of property due to restructuring or reversals of charges recorded in prior periods. In addition, the company has taken actions to reduce the amount of capital invested in facilities, including the sale-leaseback of facilities. These charges or credits are inconsistent in amount and frequency, and the company believes they are not indicative of the underlying performance of its business.

Strategic review. The company incurred expenses associated with its review of strategic alternatives that resulted in the planned separation of its HDD and Flash business units to create two independent, public companies. The company believes these charges do not reflect the company's operating results and that they are not indicative of the underlying performance of its business.

Amortization of acquired intangible assets. The company incurs non-cash expenses from the amortization of acquired intangible assets over their economic lives. Such charges are significantly impacted by the timing and magnitude of the company's acquisitions and any related impairment charges.

Recovery from contamination incident. In February 2022, a contamination of certain materials used in the company's manufacturing process occurred and affected production operations at the flash-based memory manufacturing facilities in Yokkaichi and Kitakami, Japan, which are operated through the company's joint business ventures with Kioxia Corporation (collectively, "Flash Ventures"). The contamination resulted in scrapped inventory and rework costs, decontamination and other costs needed to restore the facilities to normal capacity, and under absorption of overhead costs which were expensed as incurred. During the quarter ended December 29, 2023, the company received a partial recovery of these losses from other parties. The contamination charges and the related recovery are inconsistent in amount and frequency, and the company believes they are not part of the ongoing production operation of its business.

Other adjustments. From time to time, the company sells or impairs investments or other assets that are not considered necessary to its business operations, or incurs other charges or gains that the company believes are not a part of the ongoing operation of its business. The resulting expense or benefit is inconsistent in amount and frequency.

Income tax adjustments. Income tax adjustments include the difference between income taxes based on a forecasted annual Non-GAAP tax rate and a forecasted annual GAAP tax rate as a result of the timing of certain Non-GAAP pre-tax adjustments. The income tax adjustments also include adjustments to estimates related to the current status of the rules and regulations governing the transition to the Tax Cuts and Jobs Act and the re-measurement of certain unrecognized tax benefits primarily related to tax positions taken in prior quarters, including interest. These adjustments are excluded because the company believes that they are not indicative of the underlying performance of its ongoing business.

Additionally, free cash flow is defined as cash flows provided by (used in) operating activities less purchases of property, plant and equipment, net, and the activity related to Flash Ventures, net. The company considers free cash flow generated in any period to be a useful indicator of cash that is available for strategic opportunities including, among others, investing in the company's business, making strategic acquisitions, repaying debt and strengthening the balance sheet.
