GATX CFO Thomas Ellman Exercises Options, Sells 18,200 Shares

What Happened

• Thomas A. Ellman, EVP & CFO of GATX Corp (GATX), exercised stock options to acquire 18,200 shares on 2026-08-05 at an exercise price of $77.07 (cost $1,402,674). He then sold all 18,200 shares in open-market trades the same day for total gross proceeds of $3,277,410 (weighted avg ≈ $180.18), yielding roughly $1.87M in proceeds before taxes and fees.
• This was effectively a cashless exercise followed by immediate sales — a routine way for insiders to cover option costs and tax withholding rather than a straight directional buy.

Context

• For retail investors: exercising options and immediately selling the acquired shares is common and typically done to cover exercise costs and taxes; it does not necessarily signal a personal view on the company's long-term prospects.
• The filing provides weighted average sale info and price ranges; more granular per-price share counts can be requested from the filer or the SEC if needed.
