STX CCO Teh Ban Seng sells 15,560 shares for $12.7M via pre-arranged 10b5-1 plan

Teh Ban Seng, EVP & Chief Commercial Officer of Seagate Technology, executed a sale of 15,560 shares for $12,687,979.11 on 2026-05-13 under a pre-arranged 10b5-1 trading plan, which is a scheduled, non-discretionary transaction and therefore does not reflect current investment conviction. STX stock has appreciated significantly, with a 30-day change of +50.86% and 90-day change of +88.9%, but is currently -4.3% from its 52-week high of $841.31. The sale reduces his holdings to 3,691 shares post-transaction and represents his 28th open-market sale at Seagate over the measurement window. While the company shows strong fundamentals with latest quarter revenue of $3,112,000,000.00 and annual revenue growth of +38.9%, the elevated P/E of 116.13 reflects market expectations that may not yet be anchored in sustainable earnings power.

STX EVP/CCO Teh Ban Seng sold 20,195 shares for $8,931,994.90, reducing holdings by 86.7%.

Teh Ban Seng executed 3 separate sales totaling 20,195 shares for $8,931,994.90 at an average price of $442.29, leaving him with only 3,092 shares post-transaction (a reduction of 86.7% versus pre-transaction holdings of 23,287 shares). The timing of this near-complete liquidation is notable given that STX has appreciated 50.6% over the past 30 days and 72.9% over the past 90 days, placing the current price of $432.95 at only 3.0% below the 52-week high. His prior sale at STX on 2025-06-03 saw a +24.5% 30-day return and +39.5% 90-day return; his cross-ticker track record shows prior sells averaged +10.0% over 30 days and +25.5% over 90 days, with a 0.00% well-timed rate at the 90-day mark, meaning his recent sells at this ticker have not preceded declines. With STX trading at a P/E of 62.47 and the company showing strong quarterly fundamentals (revenue $2.8B, net income $593.0M, annual growth +38.9%), the magnitude of this position reduction warrants monitoring, though the pattern does not yet indicate prescient selling.

STX EVP Teh Ban Seng sells 6,000 shares at $270.00 ($1.6M); holdings reduced 33.3% with stock near 52-week high.

Teh Ban Seng, EVP & Chief Commercial Officer, sold 6,000 shares of Seagate Technology Holdings plc at $270.00 on 2025-11-05, reducing his holdings by 33.3% from 18,041 to 12,041 shares. The transaction occurred when STX was at $275.77 current price, representing +0.0% from the 52-week high ($66.54–$275.77), suggesting the sale took place near peak valuation levels. His prior sells at STX show mixed timing outcomes: of 4 measurable 90-day periods, 0 were well-timed (negative 90d return), with results ranging from -5.1% to +39.5% post-sale. The stock has rallied +13.6% over 30 days and +86.2% over 90 days before this transaction. With the company posting $2.6B in latest quarterly revenue, +38.9% annual growth, and a P/E of 39.79, the sale warrants observation of whether the insider's timing relative to near-peak prices and his historical pattern at this ticker signals anything material about management's forward view.

STX CCO sold 6,781 shares at $191.53; -56.6% of holdings to 5,190 shares. Stock at +0.0% 52w high, +26.5% 30d.

Teh Ban Seng sold 6,781 shares (6.8K shares) at $191.53 on 2025-09-10, reducing his stake from 11,971 shares to 5,190 shares, a -56.6% reduction in holdings. The sale occurred near the 52-week high of $196.81 with the stock up 26.5% over 30 days and 54.6% over 90 days. His prior four STX sales produced mixed results: two recent sales (2025-06-04 and 2025-06-03) showed strong 30-day and 90-day appreciation following the sales (30d +19.6% and +24.5%, 90d +36.4% and +39.5%), indicating the insider's timing on those trades was poor, while two earlier sales (2024-07-24 and 2024-06-11) showed muted gains. Across his cross-ticker track record, the 90d well-timed rate is 0.00%, meaning none of his prior four cross-ticker sells resulted in the stock falling in the subsequent 90 days. The sale represents a material reduction in his stake but does not definitively signal conviction about near-term downside given the mixed record of his prior STX transactions and the stock's strong recent momentum.

EVP Teh Ban Seng sells 74,727 shares at $120–$125 for $9.3M, reducing stake by 83.6% to 14.7K shares

Teh Ban Seng, EVP & Chief Commercial Officer at Seagate, executed 2 separate sales totaling 74,727 shares for $9,284,374.39 at blended average price $124.24 on 2025-06-03 and 2025-06-04. The sales dramatically reduced his holdings from 89,385 to 14,658 shares (an 83.6% reduction). The current stock price of $127.70 is at the 52-week high, having climbed 36.0% in the prior 30 days and 45.1% over 90 days. However, his prior 2 sales at STX show a timing pattern of 0 well-timed exits at the 90-day mark—the 2024-07-24 sale declined 5.1% in 30 days but rose 2.4% over 90 days, and the 2024-06-11 sale was up 6.1% in 30 days and 1.3% over 90 days. This current sale occurs near a multi-month price peak, following a sustained rally, and against a backdrop of annual revenue contraction of 11.3%.

EVP Teh Ban Seng sold 10,117 shares of STX at $110.00 (-65.3% of holdings) as company faces -36.7% annual revenue decline and full-year net loss.

Teh Ban Seng, Chief Commercial Officer, executed a substantial reduction of his STX position, selling 10,117 shares at $110.00 on 2024-07-24 and retaining only 5,387 shares post-transaction. The -65.3% reduction in his holdings comes against a backdrop of deteriorating fundamentals: the company reported annual revenue growth of -36.7% and posted negative full-year net income, signaling a material contraction in business performance. The sale price of $110.00 was near the top of the 52-week range ($57.97–$109.53), approximately 5.3% below the 52-week high. His prior sell at this ticker on 2024-06-11 showed a 30-day return of +6.1%, indicating the stock moved higher after that transaction; the pattern across his cross-ticker open-market history shows 1 prior sell with an average 30-day return of +6.1%, suggesting his recent sells have not preceded downturns. This sale by a senior commercial executive during a period of significant revenue and profitability deterioration warrants attention to whether the transaction reflects confidence in near-term recovery or pressure from the company's operational challenges.
