REAM JAMES B 4

What Happened
James B. Ream, a director of GATX Corporation (GATX), received a grant of 731 restricted stock units (RSUs) on April 24, 2026. The Form 4 reports the acquisition type as "A" (award/grant) at an acquisition price of $0.00. These RSUs represent the right to receive one share of GATX common stock per RSU when settled.

Key Details

• Transaction date: 2026-04-24; Form 4 filed 2026-04-28 (filed within the required reporting window).
• Transaction type/code: A = Award/Grant of RSUs.
• Shares/units granted: 731 RSUs; acquisition price shown as $0.00 on the filing.
• Shares owned after transaction: not specified in the provided filing details.
• Footnote: The RSUs are the director's annual equity retainer and will vest in full on the date of the first annual meeting of shareholders at which directors are elected following the grant date, subject to continued service. Ream elected to defer receipt of the underlying shares under the company's Directors' Voluntary Deferred Fee Plan (per footnote F1).

Context
This was a compensatory equity grant to a director (not an open-market purchase or sale). RSU grants are routine for board compensation and do not indicate an immediate cash outlay or open-market trading — the RSUs vest and are settled into shares later (or deferred per the plan). The $0.00 acquisition price reflects the grant reporting on the grant date and is common for awards; it is not a market transaction showing cash paid.
