Teh Ban Seng, EVP and Chief Commercial Officer at Seagate Technology Holdings (STX), has filed 141 Form 4 transactions, all in the single company. The pattern is entirely one-directional. Across the full history, his open-market purchases total $0, while his open-market sales total $88,515,635.98. There are no acquisitions, no grants, and no exercises that added shares. Every transaction of consequence is a sale.
The recent activity is concentrated and heavy. On September 15, 2026, Teh executed 23 separate sale transactions, all coded S, with individual values ranging from $94,470.80 to $5,650,016.52. Combined, those sales brought in roughly $37.6 million. The day before, on September 14, he exercised options at a value of $0 and sold shares worth $770,431. The recent window shows 24 sales and zero buys.
The sale sizes vary widely, which is typical of a planned disposition program rather than a single block trade. The largest single transaction, $5.65 million, and the smallest, under $100,000, both occurred on the same day. That spread suggests multiple lots sold at different prices or in different account types. The total dollar value across the recent cluster is substantial relative to the full history, meaning the pace of selling has accelerated. No purchases appear anywhere in the record, and the most recent filings continue the established sell-only direction.
