GATX CORP

We generate a significant amount of cash from operating activities and investment portfolio proceeds. We also access domestic and international capital markets by issuing debt. We use these resources, along with available cash balances, to fulfill our debt, lease, and dividend obligations, to support our share repurchase programs, and to fund portfolio investments and capital additions. We primarily use cash from operations to fund daily operations. The timing of asset dispositions and changes in working capital impact cash flows from portfolio proceeds and operations. As a result, these cash flow components may vary materially from quarter to quarter and year to year.

As of June 30, 2026, we had an unrestricted cash balance of $747.1 million. We also have a $632 million, 5-year unsecured revolving credit facility in the United States that matures in 2031 and a $368 million, 3-year unsecured revolving credit facility in the United States that matures in 2029, both of which were fully available as of June 30, 2026. In addition, we have a €250 million, 3-year unsecured revolving credit facility in Europe that matures in 2027, of which €212 million was available as of June 30, 2026. At GABX, we have a $250 million 5-year unsecured revolving credit facility in the United States that matures in 2030, all of which was fully available as of June 30, 2026.

The following table shows our cash flows from operating, investing, and financing activities for the six months ended June 30 (in millions):

Net Cash Provided by Operating Activities

Net cash provided by operating activities for the six months ended June 30, 2026 increased $189.8 million compared to the same period in 2025. Comparability among reporting periods is impacted by the timing of changes in working capital items. Specifically, higher cash receipts from revenue and lower payments for operating leases were partially offset by higher payments for maintenance, interest, income taxes, and other operating expenses.

Net Cash Used in Investing Activities

The following table shows our principal sources and uses of cash flows from investing activities for the six months ended June 30 (in millions):

(1) Portfolio investments and capital additions primarily consist of purchases of operating assets and capitalized asset improvements. See the discussions of segment operating results sections in this Item for more detail.

(2) Portfolio proceeds primarily consist of proceeds from sales of operating assets.

(3) Proceeds from sales of other assets were primarily related to railcar scrapping.

(4) In 2026, we purchased 187 railcars that were previously on operating leases, compared to 802 railcars in 2025.

The increase in portfolio investments and capital additions of $4,205.2 million for the six months ended June 30, 2026 was primarily due to the acquisition of railcars and locomotives from Wells Fargo and the cost of other railcars acquired at Rail North America and Rail India, partially offset by fewer railcars acquired at GRE. The timing of investments depends on purchase commitments, transaction opportunities, and market conditions.

Portfolio proceeds increased by $233.2 million for the six months ended June 30, 2026, primarily due to more railcars sold at Rail North America.

Net Cash Provided by Financing Activities

The following table shows our principal sources and uses of cash flows provided by financing activities for the six months ended June 30 (in millions):

(1) Cash paid for share repurchases consists of those transactions that settled during the period and includes excise taxes and commissions.
