MOSLEY WILLIAM D

William D. Mosley (CIK 0001388390, 510 transactions) has a uniquely one-sided Form 4 record at Seagate Technology Holdings plc (STX): every single buy-side event in the lifetime aggregate is zero, while the sell side totals 3,754,548 shares across 505 transactions since 2007. The most recent session on May 20, 2026 is a textbook example of how that aggregate was built — 18 consecutive market sells in one day, ranging from 80 shares at $880.19 down to 120 shares at $742.01, a single disposition order algorithmically sliced and executed across a 15-point price arc as the stock drifted lower within the session. The only non-sell event in the recent 25-transaction window is a paired option exercise on June 11, 2026: 3,319 shares exercised at $46.23 (deep in-the-money given the then-market near $750), with no corresponding sale reported in the same filing — meaning Mosley is still holding the exercised shares. Against a lifetime sell total of 3.75M shares, the one in-the-money exercise that did not immediately get sold is a small island of retention in an otherwise pure distribution profile.
