| F1 | GATX Corporation's 401(k) plan is a unitized stock fund made up of company stock plus short term investments. Because the fund includes more than company stock, participants hold units of the fund rather than company shares of stock. The number of units held by a participant may vary depending on the performance of the company stock, the overall stock market, and the amount of short term investments in the fund. Such a variance has caused the value of the units in the reporting person's 401(k) fund to be reduced without any actual disposition of shares. |
| F2 | The price of the stock is based on the closing price on December 31, 2025. |
| F3 | Consists of shares held through the GATX 401(k) Plan. |
