On October 30, 2023, Western Digital Corp. (NASDAQ: WDC) announced that the company’s Board of Directors had approved a plan to separate its HDD (Hard Disk Drive) and Flash (NAND) businesses into two independent, standalone, publicly traded companies via a tax-free spin-off to shareholders. At least initially, the goal was to complete the transaction in the second half of calendar 2024, but the most recent commentary suggests a completion date in late-February 2025. To that end, management indicates the company completed a “soft-spin” or internal separation of the two businesses at the start of its September-ending fiscal 1Q 2025 (as WDC reports on a June-ending fiscal year), publicly filed its most recent Form 10 in January 2025. Additionally, the company intends to hold a capital markets event for SpinCo, which will re-assume its original corporate moniker of SanDisk Corp. and ultimately trade under the NASDAQ ticker SNDK, on February 11, 2025, The post-spin HDD business, which will retain the Western Digital corporate identity and continue to trade under on NASDAQ under the WDC ticker, will conduct a similar investor event the following day on February 12, 2025. Upon distribution, shareholders will receive one-third of one share of SNDK for every WDC share owned as of the record date and WDC will retain a 19.9% stake in SpinCo (with definitive plans for disposal over the subsequent twelve-months following completion).
For context, in May 2016, Western Digital, which previously focused on hard disk drive memory storage, completed the acquisition of SanDisk Corporation, which focused on non-volatile Flash memory storage, for ~$19 billion in cash and stock. Subsequently, in September 2020, WDC, under the leadership of new chief executive David Goeckeler, who took the helm in March 2020, announced that it would reorganize into two distinct operating segments: (1) HDD, which generated 51.4% of consolidated sales in the June-ending F2024; and (2) Flash, which generated 48.6% of F2024 consolidated sales. Concurrently, WDC announced the hiring of Robert Soderbery, formerly of Symantec/Veritas (private) and Cisco (NASDAQ: CSCO), to be the general manager of the Flash business and shortly after, announced it had hired Ashley Gorakhpurwalla, formerly of EMC Dell (NYSE: DELL), to run the HDD segment. (At the time, management indicated the realignment of its portfolio, which, at times, is a move that has foreshadowed an eventual separation transaction that would improve the profitability, growth, and agility of each business.)
Later, in October 2021, it was reported in the Wall St. Journal that WDC may have been pursuing a merger with Kioxia Holdings, a privately held maker of flash memory chips based in Japan (with whom WDC has a long-running joint venture). In May 2022, activist-investor Elliott Management disclosed a ~1.2 million share stake in WDC (currently 2.25 million or 0.65%) and called for a full separation of the HDD and Flash businesses, which, among other things, it contended could yield a stock price of ~$100 per share by the end of 2023. In addition to its public equity investment in WDC, the investor indicated that it would also offer ~$1 billion of incremental capital into the Flash business, at a valuation of $17-$20 billion, to facilitate the separation. In June 2022, WDC announced that it was reviewing strategic alternatives, which could include the separation of its Flash and HDD businesses. More recently, in early-February 2023, activist investors Elliott Management and Apollo Global purchased $900 million of WDC’s preferred stock, in an effort to provide financial flexibility and “facilitate the next stages of Western Digital’s strategic review.” Notably, on November 26, 2023, two trading days prior to the spin announcement, it was reported in the business press that merger talks between Kioxia and WDC had fallen apart due to an objection from Korean chip maker SK Hynix, which is part of the Bain Capital investment group that purchased Kioxia, previously named Toshiba Memory, in a $9 billion transaction announced in October 2020. [Notably, Kioxia Holdings Corp. recently conducted an initial public offering on the Tokyo Stock Exchange in the latter half of December 2024.]
In terms of rationale, management indicated that the separation would “better position each business to execute innovative technology and product development, capitalize on unique growth opportunities, extend respective leadership positions and operate more efficiently with distinct capital structures.” Anecdotally, while both companies are broadly in the data storage industry, they, in fact, operate in differing businesses, both in terms of end-markets, each having their own size, cyclicality and growth prospects/cadences (i.e., enterprise cloud vs. more consumer-oriented PC, mobile and gaming), as well as capital intensity.
In terms of post-spin leadership, Mr. Goeckeler will lead the standalone Flash business, SanDisk, which precipitated the departure of Mr. Soderbery in early January 2025. Mr. Irving Tan, currently the executive vice president (EVP) of global operations, is to assume the chief executive role at the remaining HDD business, which prompted Mr. Gorakhpurwalla to assume an EVP role at Lenovo (992 HK) to lead their infrastructure solutions group in November 2024. (More recently, in mid-January 2025, WDC announced, somewhat surprisingly by all accounts, that its chief financial officer, Wissam Jabre, who was supposed to carry on that role at the standalone HDD business, would leave the company following the spin’s completion “to pursue other opportunities.” The company is conducting a “comprehensive search” for a replacement.)
On a pre-spin basis, it will be relevant, in our view, for investors to consider the mixed/disparate near-term outlook for the HDD and Flash businesses (as well as recent management changes) against the backdrop of solid longer-term demand trends. The need for data storage capacity continues to accelerate, in part driven by the needs of hyperscalers and artificial intelligence (AI) computing models, along with what appears to be an un-demanding valuation that suggests the impending transaction is poised to unlock value.
On the first point, as a standalone, WDC’s hard disk drive (HDD) business is the more stable of the two, in terms of near-term revenue, margins and cash flow trends. It also has a robust outlook, driven by increased data-center and cloud storage demand. Additionally, there is the relatively oligopolistic nature of the underlying competitive market, where WDC and Seagate Technology (NASDAQ: STX) essentially control ~80% of the share, while the Flash (or NAND, as it is commonly referred) business is grappling with pricing pressure driven by excess inventory and “choppy” demand (or what management terms as a “mid-cycle pause”) within its core personal computer (PC) and smartphone end-markets, as well as increased foreign competition (e.g., China-based Yangtze Memory Technologies). [That said, for its part, management expects the supply/demand dynamic within its Flash business will begin to improve during the back-half of calendar 2025, as excess industry inventory is drained and a potential refresh cycle in the personal computer (PC) space driven by the Windows 11 roll-out and the addition of AI capabilities ramps as well as improved capital/capacity discipline within the industry writ large (as postulated in company’s recent webcast on the subject dubbed “The New Era of NAND”).]
Also, in the longer-term, it seems apparent that the demand outlook driven by the ever increasing/secular need for storage capacity given the data needs that are emerging on many fronts, including artificial intelligence models, along with the sheer sizes of the total addressable markets support an attractive underlying industry backdrop for both businesses. (In fact, despite the current weakness in the broader industry, the enterprise Flash market is ironically perhaps better positioned than HDD looking into the next decade.)
Lastly, it appears that, at current levels, the shares trade at a valuation, which, at least to some degree, reflects the near-term uncertainty at Flash and suggests the impending transaction could unlock value, warranting a BUY recommendation. To that end, on a pre-spin basis, we fairly value shares of WDC at ~$75 per share, consisting of $16 per share for SanDisk and $59 for the remaining HDD business. On a post-spin basis, shares of SanDisk are valued at ~$37.50 per share (accounting for the one-for-three share distribution ratio and the 19.9% stake retained by its former parent), and post-spin WDC at $62 per share (including the estimated value of its retained ownership in SNDK). Upon distribution, we see heightened potential risk for initial volatility at post-spin SanDisk. This is due to the seemingly dour near-term investor sentiment, which could be exacerbated by the uncertainty regarding index inclusion, as the parent is a member of the S&P 500 Index. That said, this dynamic could ultimately present a compelling entry point for long-term investors (particularly in front of the potential for a re-rating ahead of a cyclical recovery in 2H 2025, a more disciplined pricing environment and a seemingly solid longer-term secular demand backdrop, particularly in enterprise SSD).
As mentioned earlier, the company intends to hold a capital markets event for SanDisk and the post-spin HDD business on February 11th & February 12th, respectively. At that time, the company plans to “detail more of the long-term models for each of the businesses as well as the capital allocation framework and other types of information that the investment community would be interested in leading to the actual spin,” as well as provide more granular information regarding its unconsolidated joint venture with Kioxia (which we estimate could provide a modicum of incremental upside to post-spin SanDisk’s valuation). We look forward to the event and will undoubtedly refine our current forecasts accordingly.
