GATX Corporation Reports 2005 Third Quarter Results

CHICAGO--Oct. 2, 20057, 2005--GATX Corporation today announced net income from continuing operations for the third quarter of $34.3 million or $0.61 per diluted share, compared to $48.2 million or $0.85 per diluted share in the third quarter of 2004. Income from continuing operations for the third quarter 2004 includes $0.48 per diluted share of income from an insurance recovery.

Net income from continuing operations for the nine months ending September 30, 2005 was $97.2 million or $1.75 per diluted share, compared to $87.6 million or $1.62 per diluted share in the comparable prior year period. Income from continuing operations for the first nine months of 2004 includes $0.49 per diluted share of income from insurance recoveries.

Brian A. Kenney, president and CEO of GATX, stated, "The third quarter reflects continued high asset utilization and favorable lease rate renewal pricing in Rail.

"In Air, asset utilization was at 100% and lease rates on certain aircraft types are improving. However, the air market remains challenging and we continue to actively monitor the risk of lessee defaults and asset impairments. In Specialty, the marine joint ventures continue to experience high vessel utilization and charter rates, and remarketing income on both owned and managed assets is contributing significantly to Specialty's performance.

"Investment volume from continuing operations totaled $335 million year to date versus $517 million in the comparable 2004 period. The lower 2005 investment volume primarily reflects a significant reduction in Air investments. In addition, the current investment environment in each of our markets is characterized by high asset prices and intense competition for secondary market acquisitions. We remain disciplined in our investment strategy and focused on achievement of attractive long-term returns."

Mr. Kenney concluded, "We are carefully monitoring our customer base for indications of a sustained negative impact from the recent hurricanes and continued high fuel prices. Despite this uncertainty, we currently expect 2005 GAAP earnings to be in the range of $1.90-$2.10 per diluted share versus the previously announced earnings guidance of $1.90-$2.00 per diluted share."

GATX RAIL

GATX Rail reported net income of $20.7 million in the third quarter of 2005, compared to $13.2 million in the prior year period. Year to date, GATX Rail reported $63.8 million in net income versus $44.6 million in the first nine months of 2004. Net income increased year over year primarily due to an increased number of cars on lease and higher average lease rates.

At September 30, 2005, Rail's North American fleet totaled approximately 108,000 cars. North American fleet utilization was 98%, flat with year end 2004 and the first two quarters of 2005. During the quarter, lease renewal pricing on a basket of Rail's most common car types increased approximately 11% over expiring lease rates. This compares to increases of 8% in the fourth quarter of 2004, 9% in the first quarter and 15% in the second quarter of 2005.

Rail acquired 1,678 new and used cars for its fleet during the third quarter of 2005. Year to date, GATX Rail has acquired 3,800 cars for the fleet, compared to 4,800 in the comparable 2004 period.

Maintenance expense in the third quarter was higher than the comparable 2004 period due to an increase in railcar refurbishments, conversions and wheelset replacements.

In macroeconomic data associated with GATX Rail's business, North American manufacturing capacity utilization, as reported by the Federal Reserve, was 79%, down from 80% in the second quarter 2005 and up from 78% in the third quarter 2004. Backlogs at the railcar manufacturers remained high at more than 61,000 cars at the end of the quarter. Despite hurricane-related disruptions, carloadings on the North American rails, excluding intermodal, increased 1.4% over the same period in 2004. Chemical shipments were down slightly (-0.4%) in the first nine months of 2005 versus the prior year.

GATX AIR

GATX Air reported net income of $5.3 million in the third quarter of 2005 compared to net income of $5.0 million in the prior year period. For the nine months ending September 30, 2005, GATX Air reported net income of $10.1 million compared to $9.6 million in the comparable 2004 period.

Utilization of the owned fleet was 100% at September 30, 2005 and lease rates on certain aircraft types continued to recover. However, as highlighted by the recent concurrent bankruptcy filings by two major U.S. air carriers and continued high jet fuel prices, the air market remains volatile and GATX Air continues to closely monitor its portfolio.

An updated slide presentation summarizing the GATX Air portfolio and market data is available at www.gatx.com.

GATX SPECIALTY FINANCE

GATX Specialty Finance reported net income of $13.2 million in the third quarter of 2005 compared to $6.4 million in the prior year period. Specialty reported net income for the first nine months of 2005 of $47.0 million compared to $31.4 million in the same period in 2004. The 2005 third quarter and year-to-date results reflect strong performance of the shipping joint ventures and significant remarketing income.

The Specialty portfolio currently consists of $429 million of owned assets and third-party managed portfolios totaling approximately $560 million.

CREDIT STATISTICS

Net charge-offs and impairments totaled $5.2 million in the third quarter 2005, or an annualized 0.3% of average total assets, compared to net recoveries of $0.6 million in the same period for 2004. Non-performing investments (lease receivables, finance leases, operating lease assets and loans) at the end of the 2005 second quarter totaled $52.6 million, compared to $58.6 million at the end of the third quarter 2004.

DISCONTINUED OPERATIONS

In the second quarter of 2004, GATX completed the sale of substantially all its technology leasing assets. The technology leasing segment is accounted for as a discontinued operation in all periods presented.

                             (In Millions)

Financial Performance Measures:
Ratios are based on continuing operations and are shown for the
trailing 12-months ended:

                           September 30
                      ----------------------
                         2005        2004
                      ----------  ----------
Return on equity           15.8%       12.2%
Return on assets            2.5%        1.6%
SG&A efficiency            1.75%       1.75%

The 2005 12-month trailing return measures were positively affected by
2004 non-operating events including the gain from the sale of the
Staten Island property and other tax benefits.

Definitions:
Return on equity:  Income from continuing operations divided by 
                   average total shareholders' equity.
Return on assets:  Income from continuing operations divided by 
                   average total on and off balance sheet (owned) 
                   assets.
SG&A efficiency:   Selling, general and administrative expenses (SG&A)
                   before capitalized initial direct costs (IDC) 
                   divided by average total owned and managed assets.
                   IDC are expenses incurred by GATX to originate new 
                   leases and loans which are deferred and amortized 
                   over the term of the lease or loan.

Financial performance measures disclosed in this press release are
meant to provide additional information and insight into historical
operating results and the financial position of the business.
Management uses these performance measures to assist in analyzing
GATX's underlying financial performance from period to period and to
establish criteria for making compensation decisions. GATX includes
off balance sheet assets in its return on assets calculation because
it believes that the incorporation of off balance sheet assets,
primarily railcars financed with operating leases, results in a more
accurate measure of the return GATX receives on assets in which it has
an ownership-like interest. GATX also believes that the SG&A
efficiency ratio is a more accurate measurement of how SG&A relates to
the underlying owned and managed assets, an asset base which is more
reflective of the support services and administrative activities
performed for both GATX and its customers. These measures are not in
accordance with, or a substitute for, GAAP and may be different from,
or inconsistent with, non-GAAP financial measures used by other
companies.
