      In the third quarter of 2006, GATX signed an agreement to sell the
majority of its aircraft leasing business to Macquarie Aircraft Leasing Limited
(MALL). As a result, the aircraft leasing segment is reported as discontinued
operations and prior periods have been restated to conform to the current
presentation.

      In the 2006 fourth quarter, net income from continuing operations was
$27.7 million or $.50 per diluted share, compared with net income of $9.4
million or $.19 per diluted share in the fourth quarter of 2005. The fourth
quarter of 2005 included $9.9 million or $.19 per diluted share of tax expense
associated with the repatriation of foreign earnings.

      Net income from continuing operations for the full-year 2006 was $150.5
million or $2.63 per diluted share, including a total of $9.9 million or $.16
per diluted share of benefits from a tax rate change, and derivative activity at
an affiliate. This compares with $105.6 million or $1.94 per diluted share in
the prior year, which included the aforementioned tax expense from repatriation
of foreign earnings.

      Highlights for the 2006 fourth quarter and year include:

      -     Utilization of Rail's North American fleet remained at 99% and the
            lease renewal success rate remained at a historical high throughout
            2006. In the fourth quarter, lease renewal rates increased 19% over
            expiring rates and average renewal lease term remained long at 70
            months, both on a basket of common car types.

      -     Investment volume in 2006 exceeded levels achieved in 2005 and 2004.
            Total investment volume reached $763 million in 2006, up from $503
            million in 2005 and $535 million in 2004.

      -     On November 30, 2006, GATX sold its wholly-owned aircraft to MALL.
            On January 17, 2007, GATX sold its interests in joint venture
            aircraft to MALL, completing GATX's exit from the aircraft leasing
            business.

      -     American Steamship Company (ASC) results improved in 2006 due to the
            contribution from the six vessels purchased in June from Oglebay
            Norton, increasing rates, and favorable operating conditions on the
            Great Lakes.

      Brian A. Kenney, president and CEO of GATX, stated, "Our 2006 results
reflect continuing strength in our markets. Net income from continuing
operations increased substantially over 2005. We grew our rail, marine and
industrial equipment assets while maintaining our disciplined investment
approach. We also improved the risk profile of the Company through the sale of
the air business, and this is reflected in our higher credit ratings. GATX
earned a return on equity from continuing operations of approximately 14% in
2006 -- a return that I believe is attractive on a risk-adjusted basis given our
new business mix.

      "We expect that GATX will show continued improvement in financial returns
in 2007. Average lease rates in Rail should continue increasing, and we will
work hard to continue extending average lease terms. We invested $534 million in
rail assets in 2006, representing a 33% increase over 2005 investment volume of
$403 million. This is encouraging given the historically high price for new
railcars and intense competition in the secondary market. Despite signs of
increasing weakness in certain segments of the freight car market, we expect
Rail's income contribution to increase significantly in 2007."

      Mr. Kenney continued, "Net income at Specialty was down slightly in 2006,
as the shipping market cooled from its record-breaking performance in 2005.
Vessel utilization remained high and even with the expected decrease in rates,
our shipping joint ventures performed very well. We expect similar results from
these joint ventures in 2007. Asset remarketing income, primarily from the
managed portfolios, was stronger than originally expected in 2006. In 2007, we
expect Specialty's income contribution to decline versus 2006 as we do not
anticipate the same level of remarketing gains that were achieved in the prior
year.

      "ASC's operating performance in 2006 improved due to the contribution of
the six vessels acquired in June and the strong market environment. We expect
similar operating performance in 2007. Due to this acquisition and the sale of
the Air leasing business, we will break out ASC as a segment for financial
reporting purposes, beginning with the Form 10-K to be filed later this quarter.

      "As a result of the successful completion of the Air sale and factors such
as our current outlook for investment volume and leverage, the GATX Board of
Directors has authorized a $300 million share repurchase program. This
authorization enables GATX to return a sizable portion of the net Air sale
proceeds to shareholders while also providing the continued flexibility to
invest in rail, marine, and industrial equipment assets -- and to do so even
more aggressively when warranted by asset prices."

      Mr. Kenney concluded, "We look forward in 2007 to capitalizing on
continued strength in the rail market and more fully capturing the benefits of
refocusing the Company on its most attractive assets. We expect 2007 income from
continuing operations to be in the range of $2.90-$3.10 per diluted share,
representing a substantial increase over 2006 levels. This reflects expectations
for continued improvement in Rail's income contribution, a decrease in
Specialty's income versus recent high levels, and the positive impact of a lower
share count."

GATX RAIL

      Rail reported net income of $26.9 million in the fourth quarter of 2006,
compared with $17.9 million in the fourth quarter of 2005. For the full year,
Rail reported $116.4 million in net income versus $81.7 million in 2005. Net
income increased year over year primarily due to an increased number of cars on
lease, higher average lease rates, improved contributions from European
operations, and increased remarketing income. The 2006 full-year results include
$4.0 million of after-tax benefit related to derivative activity at an affiliate
and $5.9 million of deferred tax benefits from an enacted reduction in Canadian
statutory tax rates, while the 2005 fourth quarter and full-year results
included $5.3 million of tax expense related to the repatriation of foreign
earnings.

      At December 31, 2006, Rail's North American fleet totaled more than
110,000 cars and fleet utilization remained at 99% each quarter in 2006, up from
98% at year end 2005.

      During the fourth quarter, lease renewal pricing on a basket of Rail's
most common car types increased 19% over expiring lease rates, comparable to the
prior quarter. Rail also extended the average term on basket renewals during the
fourth quarter to 70 months, compared with 62 months in the fourth quarter of
2005. This action is expected to temper future earnings volatility.

      Total investment volume at Rail was $534 million, up from $403 million in
2005 and $490 million in 2004. Rail acquired 6,302 cars for its North American
fleet during 2006, comprised of 3,495 new and 2,807 used railcars, and sold or
scrapped 3,975 cars. These actions created net growth in the fleet of more than
2,300 cars during the year. Many of the new railcars were acquired at advantaged
prices through our Committed Purchase Program. Additionally, Rail's success in



Page 4

acquiring used railcars is a result of a proactive initiative to target certain
used car types. Rail also identified additional attractive investment
opportunities in Europe, investing more than $45 million in this important
market.

      In macroeconomic data related to Rail's business, North American
manufacturing capacity utilization, as reported by the Federal Reserve, was 82%
in December 2006, up from 81% in the same period 2005. Backlogs at the railcar
manufacturers, as reported by the Railway Supply Institute, totaled nearly
86,000 cars at the end of the fourth quarter 2006, up from approximately 69,000
during the same period 2005 and down from 88,000 in the third quarter 2006.
Carloadings on the U.S. rails, excluding intermodal, as reported by the
Association of American Railroads, increased 1.2% over 2005. Chemical shipments
were down 1.1% in 2006 versus 2005.

GATX SPECIALTY

      Specialty reported net income of $7.0 million in the fourth quarter of
2006 compared with $4.8 million in the prior year period. For the full-year
2006, Specialty reported net income of $55.1 million, compared with $60.9
million in 2005. Both 2006 and 2005 results reflect very strong remarketing
activity. The 2006 results also reflect marine joint venture income that slowed
as expected from record levels in 2005.

      Remarketing gains in 2006 were robust, totaling $27.9 million, comprised
of $.8 million from gains on sales of owned assets and $27.1 million in residual
sharing income from the managed portfolio. Similarly, in 2005, remarketing gains
at Specialty totaled $28.1 million. These high levels of remarketing activity
are not expected to occur again in 2007.

      Note that the Specialty segment now includes the results of GATX's 50%
interest in the aircraft engine leasing joint venture, Rolls-Royce & Partners
Finance, which was previously included in the Air segment. GATX plans to retain
its interest in this investment. Prior periods have been restated to conform to
the current presentation.

      The Specialty portfolio currently consists of approximately $500 million
of owned assets (including on and off balance sheet assets) and third-party
managed portfolios totaling approximately $470 million.

DISCONTINUED OPERATIONS

      In the third quarter of 2006, GATX signed an agreement to sell the
majority of its aircraft leasing business to MALL. The sale of the wholly-owned
aircraft was completed on November 30, 2006 and sale of the interests in joint
venture aircraft was completed on January 17, 2007.



Page 5

      In addition to the sale to MALL, GATX sold 27 aircraft to AerCap in the
latter half of the year, and in July 2006 completed the sale of GATX's share of
the Pembroke joint venture to management.

      In the first quarter of 2007, GATX will record final Air sale purchase
price adjustments in Discontinued Operations; adjustments are not expected to be
material to GATX's overall financial position.

SEGMENT REPORTING

      Based on GATX's exit from the aircraft leasing business, the Company may
reformat segment results in the future. Any changes to segment reporting will be
detailed in the Company's 2006 Annual Report on Form 10-K.
