WDC WESTERN DIGITAL CORP Insider Trading

Director Martin I Cole sold 3,280 shares at $511.16 avg on 2026-06-09 per 10b5-1 plan adopted 2026-03-05

Director Martin I Cole executed 30 separate sales totaling 3,280 shares for $1,676,600.51 on 2026-06-09, reducing his holdings by -11.1% from 29,433 shares to 26,153 shares. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2026-03-05, meaning it is scheduled rather than discretionary. His prior open-market sales across all tickers show an average 90-day return of +91.1%, and his five prior sales at WDC specifically averaged 90-day returns ranging from +88.4% to +98.4%. The current stock price is $529.29, compared to the blended sale price of $511.16 and a 52-week high of $602.54. Fundamental metrics show annual revenue decline of -26.8% and a P/E of 99.68, suggesting a growth multiple positioned on elevated valuations despite near-term revenue headwinds.

Chief of Global Operations sells 2,475 WDC shares at $556.24 for $1.4M; price at -0.2% from 52-week high.

Vidyadhara K Gubbi sold 2,475 shares (2.8% of his pre-transaction holding) at $556.24, near the 52-week high of $564.14. His prior 5 trades at WDC have all shown positive 90-day returns, with an average of +73.2% across his cross-ticker open-market history, but a 0.00% well-timed rate at the 90-day mark—meaning none of his prior WDC sales captured declines afterward; the stock rose after each sale. The $1.4M transaction size is modest relative to his 85,154 share post-transaction holding, and the stock has appreciated 30.5% in the 30 days prior and 115.5% in the 90 days prior to this sale. Fundamentally, the company reports a -26.8% annual revenue decline and a 106.05 P/E ratio, suggesting valuation multiples remain elevated despite the growth headwind.

Chief Sales & Marketing Officer sells 10,000 WDC shares in single-day disposition worth ~$5M; all prior exits were poorly timed as stock rallied afterward.

Davis Brian Scott, Chief Sales & Marketing Officer at Western Digital, executed a substantial single-day disposition of 10,000 shares on May 11, selling across 18 separate transactions. This is Scott's 13th through 30th open-market sale in the 36-month window—a relentless pattern of equity liquidation with zero open-market purchases during this period. Examining his track record in this stock specifically, all five of his prior sales proved poorly timed: the stock rose significantly in the periods following each exit, meaning Scott has consistently sold before rallies rather than ahead of declines. The current sale occurs with the stock trading well below its 52-week high despite posting strong quarterly results with profitability and substantial revenue growth. The timing is notable: Scott sold as the stock has gained sharply over the past three months, yet his historical record suggests he may not have caught the optimal exit point—prior sells have consistently been followed by further appreciation, not deterioration.

Chief of Global Operations sells ~2 million in WDC shares near 52-week highs as stock surges.

Gubbi Vidyadhara K, Western Digital's Chief of Global Operations, sold approximately 4,674 shares worth roughly $2.07 million on the day of this filing. The stock is trading at its highest point in the past year after rallying significantly over the prior three months, suggesting this sale took place at or near peak valuation rather than during a dip. While the company remains profitable and has demonstrated exceptional quarterly earnings, the stock is trading at a stretched multiple relative to its fundamentals. An insider at this operational level selling a material stake during a strong momentum period—rather than during weakness—warrants attention, especially given the significant distance the stock has traveled in recent weeks. This move lacks the typical hallmarks of conviction-driven insider accumulation and instead appears more consistent with portfolio rebalancing or profit-taking at elevated prices.

WDC CEO Tan Irving sells $8.2M in stock near all-time highs; profitable fundamentals but elevated valuation

Tan Irving, Western Digital's Chief Executive Officer, executed a substantial programmatic sale of roughly 19,500 shares across multiple transactions on a single trading day, totaling over $8.2 million. The timing is notable: the stock is trading at its all-time high following a sharp rally, and the CEO is selling into strength rather than buying weakness—a pattern that typically suggests he views current valuations as attractive for reducing exposure. While Western Digital remains fundamentally sound with strong recent profitability and robust revenue generation, the company's valuation has expanded significantly, trading at a notably elevated multiple. As the chief executive with direct operational visibility, Irving's decision to lock in gains at peak price levels warrants attention as a potential signal that he sees limited upside at current levels or wishes to diversify his concentrated holding.

Chief of Global Operations sold 8,518 WDC shares at $255.32 on 2026-03-06 for $2.2M; holdings reduced to 99.3K shares.

Gubbi Vidyadhara K, Chief of Global Operations, executed a $2,174,858.35 sale of 8,518 shares at $255.32, reducing his holdings by -7.9% to 99.3K shares. The timing of this sale—just two days after two other sales on 2026-03-04 (outcomes not yet measurable)—and within a period where WDC has declined -5.8% over 30 days yet risen +46.3% over 90 days, suggests this was part of a sequence of disciplined liquidations. At the same ticker, his prior three measurable sells on 2025-12-04 and 2025-12-05 each posted positive 90-day returns (ranging +53.7% to +63.4%), indicating the stock subsequently climbed after those sales—a poorly-timed pattern for a seller. Against this backdrop of sub-optimal prior timing at WDC and amid a company reporting -26.8% annual revenue growth and a high P/E of 50.14, the cluster of consecutive sell days warrants monitoring to determine whether this shift in cadence signals a directional view or logistical portfolio management.

WDC CLO Tregillis sells 9.3K shares for $2.5M at blended avg $268.27; stock down 12.7% from 52-week high

Tregillis executed 2 separate sales totaling 9,324 shares for $2,501,381.80 at a blended average price of $268.27, reducing her holdings by 7.1% to 121,682 shares. The current stock price of $259.03 is 12.7% below the 52-week high of $296.56 and reflects a 10.8% decline over the past 30 days, though it has appreciated 53.4% over 90 days. Against her prior trade at WDC on 2025-08-22, which posted a 90-day return of +87.5%, this current sale occurs at a modestly elevated valuation; however, the company's annual revenue growth of -26.8% and elevated P/E of 48.78 suggest a market premium amid fundamental contraction. With a market capitalization of $87.8B and recent quarterly net income of $1.8B, the scale of the sale represents a deliberate, material reduction in her direct equity stake.

WDC CFO Gubbi Vidyadhara K sold 10,148 shares for $2.7M on 2026-03-04; holds 107.8K post-transaction

Gubbi Vidyadhara K, Chief of Global Operations at Western Digital, executed two separate sales totaling 10,148 shares on 2026-03-04, netting $2,743,110.02 at a blended average price of $270.31 per share. His post-transaction holding of 107,794 shares represents an 8.6% reduction from the pre-transaction level of 117,942 shares. The current stock price of $259.03 sits 12.7% below the 52-week high of $296.56 and has declined 10.8% over the past 30 days, despite a 53.4% gain over the past 90 days. Notably, his four prior sales at WDC all showed positive 90-day returns (ranging from 53.7% to 72.3%), indicating those sales were poorly-timed exits from a rising stock; his same-ticker timing pattern at WDC shows 0 of 4 prior sells were well-timed. The company's annual revenue growth of −26.8% and high P/E of 48.78 frame this insider activity against a backdrop of contraction, though the latest quarter generated $3.0B in revenue and $1.8B in net income.

WDC Director Cole Martin I sells 6,000 shares for $1.6M at $271.67 avg, stock now $250.61

Cole Martin I, a WDC Director, executed 14 separate sales totaling 6,000 shares for $1,630,001.81 on 2026-03-02, reducing his holdings by 16.9% from 35.4K to 29.4K shares. The sales occurred across a narrow price range ($263.66–$280.72), with a blended average of $271.67. The stock has since declined to $250.61 (current price), placing the transaction 15.5% below the 52-week high of $296.56. His prior five trades at WDC (all sells on 2025-11-05) exhibited strong 90-day performance (range +82.4% to +89.7%), though none were well-timed in the sense that the stock rose following each sale rather than falling. The company's fundamentals show annual revenue declined 26.8% year-over-year, though the latest quarter posted $3.0B in revenue and $1.8B in net income. Context matters: the timing relative to fundamentals and whether subsequent price action validates or contradicts this director's exit requires ongoing monitoring.

WDC CSO Brian Scott Davis sells 10,000 shares ($2.8M) on 2026-02-17 across 12 transactions; holds 121.8K shares post-sale.

Davis conducted 12 separate sales totaling 10,000 shares for $2,791,602.98 at prices ranging from $272.97 to $285.01, with a blended average price of $279.16. This represents a 7.6% reduction of his pre-transaction holdings (131.8K shares), bringing his post-sale position to 121.8K shares. The stock has appreciated significantly in the recent period (90-day change: +104.5%; 30-day change: +27.7%), trading near its 52-week high at current price $284.67. The sale occurred amid a challenging operational backdrop: annual revenue contracted 26.8% year-over-year despite a strong quarterly net income of $1.8B on $3.0B revenue, and the stock's elevated valuation (P/E: 53.61) sits well above the long-term median. The execution of multiple tranches across a narrow price band ($272.97–$285.01) captures positions within recent momentum without indicating a directional conviction statement.
