Cynthia L. Tregillis, Western Digital's Chief Legal Officer and Corporate Secretary, sold 438 shares of common stock on February 23 and 24, 2026, for about $123,661 under a Rule 10b5-1 plan. The transactions accompany other insider activity to cover taxes and follow corporate moves including redemption of 4.750% senior notes due 2026, a planned Sandisk share sale, analyst price target increases and a roadmap toward 100TB drives by 2029.

Key Points

  • Cynthia L. Tregillis sold 438 shares on Feb. 23-24, 2026, for about $123,661 at prices between $281.70 and $283.83 under a Rule 10b5-1 plan.
  • Tregillis converted dividend equivalent rights into 12 shares (value $0) and surrendered 1,353 shares to cover taxes at $285.52, totaling $386,308; she now directly owns 134,759 shares.
  • Western Digital completed redemption of its 4.750% Senior Notes due 2026, is selling up to 7.5 million Sandisk shares (with proceeds not directly benefiting Sandisk), and announced a roadmap toward 100TB HAMR drives by 2029 amid analyst price target increases.

Western Digital Corporation's Chief Legal Officer and Corporate Secretary, Cynthia L. Tregillis, reported the sale of 438 shares of the company's common stock on February 23 and 24, 2026, for an aggregate amount of approximately $123,661. The individual sale prices recorded in the Form 4 filing with the Securities and Exchange Commission ranged from $281.70 to $283.83.

The filing states the trades were carried out under an existing Rule 10b5-1 trading plan that Tregillis adopted on May 23, 2025. That plan provided the framework for these automatic transactions, according to the disclosure.

The SEC filing also documents additional activity by Tregillis in the same period. On February 20 and 21, she acquired 12 shares of Western Digital common stock by converting dividend equivalent rights; the filing lists the value of those shares as $0. Separately, a block of 1,353 shares was surrendered to satisfy tax obligations at a price of $285.52 per share, producing a total value of $386,308 for that disposition.

After these movements, Tregillis is shown on the filing as the direct owner of 134,759 shares of Western Digital stock.


Context and market commentary

InvestingPro analysis cited in the filing characterizes the stock as appearing overvalued relative to its stated Fair Value metric, while noting that 17 analysts have revised their earnings estimates for the company upward for the upcoming period. The filing points readers to a Pro Research Report for investors seeking more detailed coverage across Western Digital and other U.S. equities.

Separately noted in the company filings and disclosures, Western Digital has completed the redemption of its 4.750% Senior Notes due in 2026. That capital allocation move follows the company's decision to sell up to 7.5 million shares of Sandisk - a transaction structure in which Sandisk will not receive direct benefit from the proceeds, per the documentation.

Analyst reactions cited in company communications have been favorable: Cantor Fitzgerald raised its price target to $420 on the company, attributing the change to technological progress and an updated financial model discussed at the company's Innovation Day event. Morgan Stanley likewise increased its price objective to $369, pointing to expanding demand for AI-driven data storage as a key consideration.

On the product front, Western Digital disclosed a storage roadmap that includes a 40TB UltraSMR ePMR hard drive now, and a plan to scale to 100TB using HAMR technology by 2029. The company says the roadmap is aligned with its efforts to serve AI data requirements and includes work with hyperscale customers.


Takeaway

The filings show a mix of routine insider selling executed under a pre-established 10b5-1 plan and separate dispositions to meet tax obligations. Those moves sit alongside corporate actions - debt redemption, a partial Sandisk share sale, analyst target increases and a multi-year product roadmap - that the company highlights as part of its strategy to address AI-driven storage demand.

Risks

  • Insider sales and tax-related dispositions may be interpreted differently by market participants, potentially affecting investor sentiment in the data storage sector.
  • The company’s planned Sandisk share sale and debt redemption involve capital allocation choices that could influence balance sheet liquidity and investor perception in the storage and corporate debt markets.
  • Execution risk on the multi-year storage roadmap - including scaling HAMR technology to 100TB by 2029 - could affect Western Digital’s position with hyperscale customers and the broader AI-driven storage market if timelines or performance deviate from plans.
