FOR RELEASE: IMMEDIATE

GATX CORPORATION REPORTS 2013 THIRD QUARTER RESULTS

CHICAGO, IL, October 24, 2013 - GATX Corporation (NYSE:GMT) today reported 2013 third quarter net income of $53.8 million or $1.15 per diluted share, compared to net income of $53.8 million or $1.13 per diluted share in the third quarter of 2012. The 2013 and 2012 third quarter results include benefits from Tax Adjustments and Other Items of $2.8 million or $.06 per diluted share and $18.2 million or $.38 per diluted share, respectively.

Net income for the first nine months of 2013 was $116.0 million or $2.45 per diluted share, compared to $107.6 million or $2.26 per diluted share in the prior year period. The 2013 and 2012 year-to-date results include benefits from Tax Adjustments and Other Items of $4.5 million or $.09 per diluted share and $0.7 million or $.02 per diluted share, respectively. Details related to the Tax Adjustments and Other Items are provided in the attached Supplemental Information.

Brian A. Kenney, president and chief executive officer of GATX, said, “The demand for tank cars in North America remains strong. During the third quarter, the renewal rate change of GATX’s Lease Price Index (“LPI”) was a positive 34.3% and the average renewal term for cars in the LPI was 63 months. Freight car markets are uneven, although demand for grain and coal cars improved modestly from very low levels.

“Within Rail International, we sold our 37.5% interest in AAE Cargo AG during the quarter. GATX Rail Europe (“GRE”), our wholly-owned tank car leasing business, is now better positioned to pursue opportunities in the European freight car market. GRE continues to have solid performance as we are investing in new tank cars and aggressively scrapping older equipment. Fleet utilization was 96.3% at the end of the third quarter.”

Mr. Kenney continued, “American Steamship Company (“ASC”) operated thirteen vessels during the quarter, as weather conditions were favorable and water levels normalized. Customer demand remains in line with expectations. Within the Portfolio Management segment, the Rolls-Royce and Partners Finance joint ventures continue to have strong operating results.”

Mr. Kenney concluded, “We continue to expect 2013 full year earnings to be in the range of $3.20 - $3.30 per diluted share. This guidance excludes any impact from Tax Adjustments and Other Items.”

RAIL NORTH AMERICA

Rail North America reported segment profit of $57.9 million in the third quarter of 2013, compared to $45.6 million in the third quarter of 2012. Year to date, Rail North America reported segment profit of $156.4 million, compared to $149.5 million in the same period of 2012. The increase in quarterly and year-to-date segment profit was driven by higher lease rates and improved asset remarketing results, partially offset by an expected increase in maintenance expense related to regulatory compliance work.

At September 30, 2013, Rail North America's wholly-owned fleet totaled approximately 110,000 cars, and fleet utilization was 98.5% compared to 98.2% at the end of the second quarter and 98.2% at September 30, 2012. During the third quarter of 2013, GATX's Lease Price Index (“LPI”), a weighted average lease renewal rate for a group of railcars representative of Rail North America's fleet, increased 34.3% over the weighted average expiring lease rate. This compares to a 36.0% increase in the prior quarter and a 26.4% increase in the third quarter 2012. The average lease renewal term for cars included in the LPI during the third quarter was 63 months, compared to 58 months in the second quarter and 59 months in the third quarter of 2012.

Rail North America's investment volume was $130.8 million during the third quarter, and included the purchase of new tank and freight cars.

RAIL INTERNATIONAL

Rail International reported segment profit of $34.8 million in the third quarter of 2013, compared to $17.9 million in the third quarter of 2012. The 2013 and 2012 third quarter results include the pre-tax benefit from Other Items of $15.1 million and the negative pre-tax impact from Other Items of $2.1 million, respectively. Excluding the impact from Other Items, third quarter segment profit was comparable to the prior year period.

Rail International reported segment profit of $77.8 million year-to-date 2013, compared to $22.2 million in 2012. The 2013 and 2012 results include the pre-tax benefit from Other Items of $17.0 million and the negative pre-tax impact from Other Items of $20.9 million, respectively. The increase in year-to-date segment profit was driven by increased lease income, scrapping gains, and fewer maintenance events, partially offset by higher depreciation expense at GRE.

GRE’s fleet totaled approximately 22,000 railcars as of September 30, 2013, and utilization was 96.3%, compared to 95.8% at the end of the second quarter and 96.6% at September 30, 2012.

During the third quarter, Rail International's investment volume was $43.7 million, primarily for new tank cars in Europe.

Additional current and historical fleet and operating data as well as macroeconomic data related to Rail North America's and Rail International's businesses can be found on the last page of this press release.

AMERICAN STEAMSHIP COMPANY

American Steamship Company (“ASC”) reported segment profit of $12.9 million in the third quarter of 2013, comparable to segment profit of $13.2 million in the third quarter 2012.

Segment profit year-to-date 2013 was $23.8 million, compared to $29.3 million year-to-date 2012. The decline in year-to-date segment profit was due to operating delays and low water levels early in the sailing season, and modestly lower iron ore tonnage.

PORTFOLIO MANAGEMENT

Portfolio Management reported segment profit of $17.7 million in the third quarter of 2013 compared to $15.0 million in the third quarter of 2012. The increase in segment profit was attributable to modest improvement from vessels operating in certain ocean-going markets.

Year to date, Portfolio Management reported segment profit of $47.5 million compared to $51.6 million in the same period of 2012. The decline in segment profit was driven by lower lease revenues due to equipment sales and the absence of warrant income recorded in the prior year, partially offset by the modest improvement from certain ocean-going vessels.

The Portfolio Management segment currently consists of approximately $852 million of owned assets and third-party managed portfolios of approximately $128 million.

 _________

(a) GATX's Lease Price Index ("LPI") is an internally-generated business indicator that measures general lease rate pricing on renewals within its North American railcar fleet. The index is calculated using the weighted average lease rate for a group of railcar types that GATX believes best represents its overall North American fleet. In addition, this representative group of North American railcars is used to calculate an average renewal lease rate change and an average renewal term. The average renewal lease rate change is the percentage change between the weighted average renewal lease rate and the weighted average expiring lease rate. The average renewal lease term index is reported in months.  It reflects the average renewal lease term of railcar types in the LPI weighted by fleet composition.

(b) As reported and revised by the Federal Reserve.

(c) As reported by the Association of American Railroads (AAR).

(d) As reported by the Railway Supply Institute (RSI).
