Jennifer L. Hamann's Form 4 record at Union Pacific Corp shows a distinctive monthly award cadence, and the prices attached to those awards trace a real price trajectory: from $216.32 in May 2025 down to $215.19 in September 2025, then climbing steadily to $225.45 in October, $250.21 by March 2026, and $267.03 by June 2026 — roughly a 24% increase from the September 2025 low. These monthly grants are small, typically 4 to 11 shares. Layered on top are larger, less frequent events: a February 12, 2026 cashless exercise, in which 4,243 shares were exercised at a $124.86 strike price (in two tranches) alongside 2,918 shares withheld for taxes at $262.81, and an April 24, 2026 open-market sale of 2,000 shares at $274.70. A December 4, 2025 transaction (code G) transferred 300 shares as a gift, separate from any sale. Across the full Union Pacific relationship, 121 transactions since January 2020 have moved 63,367 shares, all sales or compensation-related, with zero purchases. A newer, smaller relationship at Steel Dynamics Inc, active since November 2023, shows 21 transactions, all stock-award grants of irregular size — 15 to 146 shares — with neither purchases nor sales recorded in the aggregate totals.
