SAN JOSE, Calif., — January 28, 2021 — Western Digital Corp. (Nasdaq: WDC) today reported fiscal second quarter 2021 financial results.

“The team delivered solid results this quarter, especially as we continue adapting our business and technology portfolio to take advantage of the immense opportunities in the storage industry,” said, David Goeckeler, Western Digital CEO. “During the quarter, we captured strength in the retail business and also delivered on our target outcome to complete qualification of our energy-assisted hard drives and second-generation enterprise SSD products with some of the world’s largest data center operators. While there is still more work to be done, we remain extremely focused on meeting the needs of our customers and ramping our next-generation products throughout calendar 2021.”

Total Revenue$3,943$4,234down 7%

In the fiscal second quarter of 2021, Western Digital’s revenue decreased 7% year-over-year to $3.9 billion. The decrease is largely attributable to a decline in our Data Center Devices & Solutions end market, more than offsetting growth in Client Devices and Client Solutions.

In Client Devices, Western Digital’s industry leading NVMe-based client SSDs and strong relationships with major PC OEMs drove a record level of exabyte shipments. The pandemic has not only accelerated the digital transformation, but it has also spurred technological innovation, driving the ability to access the cloud using very powerful and advanced end-devices. The ability to access, store, and share data from anywhere, on any device, has resulted in robust storage demand for notebook, tablet, and Chromebook devices.

In Data Center Devices & Solutions, qualifications of the second-generation eSSD products have progressed well, with nearly 150 qualifications completed, including at one cloud titan. There has been solid progress made completing the qualifications of our energy-assisted hard drives, including at three of the four US cloud titans. While one now-completed cloud titan qualification slipped beyond our anticipated timeline in the fiscal second quarter, another cloud titan qualification was completed, ahead of schedule. With cloud digestion abating and the stabilization of OEM demand, we believe the demand in capacity enterprise bottomed in the fiscal second quarter and are anticipating a rebound in the fiscal third quarter.

In Client Solutions, revenue increased during the seasonally strong quarter, to a two-year high. This solid performance was driven by continued growth in retail, supported by the strength of our brand and the breadth of our portfolio.

(1) Non-GAAP gross margin guidance excludes amortization of acquired intangible assets and stock-based compensation expense, totaling approximately $40 million to $60 million. The company’s non-GAAP operating expenses guidance excludes amortization of acquired intangible assets; stock-based compensation expense; and employee termination, asset impairment and other charges, totaling approximately $50 million to $70 million. The company's non-GAAP interest and other expense guidance excludes approximately $10 million of convertible debt activity. In the aggregate, non-GAAP diluted earnings per share guidance excludes these items totaling $100 million to $140 million. The timing and amount of these charges excluded from non-GAAP gross margin, non-GAAP operating expenses, non-GAAP interest and other expense, net 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 interest and other expense, non-GAAP tax rate and non-GAAP diluted earnings per share to the most directly comparable GAAP financial measures (gross margin, operating expenses, interest and other expense, tax rate and diluted earnings per share, respectively) are not available without unreasonable effort.
(2) The non-GAAP tax rate provided is based on a percentage of non-GAAP pre-tax income.

To supplement the condensed consolidated financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”), the table above sets forth non-GAAP cost of revenue; non-GAAP gross profit; non-GAAP operating expenses; non-GAAP operating income; non-GAAP interest and other expense, net; non-GAAP income tax expense; non-GAAP net income; non-GAAP diluted income 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, the amortization of acquired intangible assets, stock-based compensation expense, employee termination, asset impairment and other charges, charges related to acquisitions and dispositions, charges related to cost saving initiatives, charges related to a power outage incident and related recovery, convertible debt activity, other adjustments, and income tax adjustments, and 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:

Amortization of acquired intangible assets. The company incurs 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.

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.





Employee termination, asset impairment and other charges. 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. These charges (including any reversals of charges recorded in prior periods) are inconsistent in amount and frequency, and the company believes they are not indicative of the underlying performance of its business.

Charges related to acquisitions and dispositions. In connection with the company's business combinations or dispositions, the company incurs expenses which it would not have otherwise incurred as part of its business operations. These expenses include third-party professional service and legal fees, third-party integration services, severance costs, non-cash adjustments to the fair value of acquired inventory, contract termination costs, and retention bonuses. The company may also experience other accounting impacts in connection with these transactions. These charges and impacts are related to acquisitions and dispositions, are inconsistent in amount and frequency, and the company believes they are not indicative of the underlying performance of its business.

Charges related to cost saving initiatives. In connection with the transformation of the company's business, the company incurred charges related to cost saving initiatives which do not qualify for special accounting treatment as exit or disposal activities. These charges, which the company believes are not indicative of the underlying performance of its business, primarily relate to costs associated with rationalizing the company's channel partners or vendors, transforming the company's information systems infrastructure, integrating the company's product roadmap, and accelerated depreciation of assets.

Charges related to a power outage incident and related recovery. In June 2019, an unexpected power outage incident occurred at the flash-based memory manufacturing facilities operated through the company's joint venture with Kioxia Corporation in Yokkaichi, Japan. The power outage incident resulted in costs associated with the repair of damaged tools and the write-off of damaged inventory and unabsorbed manufacturing overhead costs which are expensed as incurred. In the fiscal first and second quarters of 2021, the company received recoveries of these losses from insurance carriers. These charges and recoveries are inconsistent in amount and frequency, and the company believes these charges or recoveries are not part of the ongoing production operation of its business.

Convertible debt activity. The company excludes non-cash economic interest expense associated with its convertible notes. These charges do not reflect the company's operating results, and the company believes they are not indicative of the underlying performance of its business.




Other adjustments. From time-to-time, the company incurs 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. These adjustments are excluded because they are infrequent and the company believes that they are not indicative of the underlying performance of its business.

Additionally, free cash flow is defined as cash flows provided by operating activities less purchases of property, plant and equipment, net of proceeds from sales of property, plant and equipment, 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.
