FOR IMMEDIATE RELEASE

AMB PROPERTY CORPORATION ANNOUNCES FOURTH QUARTER AND FULL YEAR 2004 RESULTS

Improving Industrial Fundamentals Drive Strong Operating Results; Global Development Pipeline and New Private Capital Vehicles Provide for Future Growth

SAN FRANCISCO, February 1, 2005 – AMB Property Corporation (NYSE:AMB), a leading global developer and owner of industrial real estate, today reported fourth quarter and full year 2004 earnings per share (EPS) of $0.65 and $1.39, respectively, exceeding the company’s guidance of $0.47 to $0.57 for the quarter and $1.20 to $1.30 for the year. The better-than-expected EPS results stem primarily from higher gains on sales of operating properties associated with the company’s continued refinement of its portfolio.

Fourth quarter 2004 EPS increased 117% from EPS of $0.30 in the same period of 2003. EPS for fourth quarter 2004 included $0.40 per share in net gains on dispositions of real estate while the same period in the prior year included $0.04 per share in net gains. Full year 2004 EPS decreased 1.4% from EPS of $1.41 in 2003. Full year 2004 results include $0.55 of net gains on dispositions compared with $0.61 of net gains in 2003.

Operating Results

The company’s industrial operating portfolio was 94.8% leased as of December 31, 2004, up 20 basis points from September 30, 2004, and up 170 basis points from December 31, 2003. Preliminary data indicate U.S. industrial vacancy at the end of the fourth quarter was 10.9%, representing a 30 basis point improvement from the prior quarter - the third consecutive quarter of improving occupancy nationally.

Cash-basis same store net operating income (NOI) increased 0.4% in fourth quarter 2004, driven primarily by occupancy gains. For the full year 2004, same store NOI declined 0.9%, representing the impact of rental rate decreases on leases renewed or rolled over during the past 12 months, partially offset by occupancy increases.

Hamid R. Moghadam, chairman and CEO, said, “Demand fundamentals for industrial real estate continue to show positive momentum. The fourth quarter marked the largest quarterly gains in both the Industrial Production and Manufacturing Output indexes since the fourth quarter of 1999. Growth in business inventories is strong and broadly based across the manufacturing, retail and wholesale sectors. This macro activity supported a second consecutive quarter of national industrial real estate absorption in excess of 50 million square feet, well above the 10-year average of 33 million square feet per quarter. AMB’s portfolio has gained occupancy consistently over the course of the year with the strongest demand for distribution space coming from markets tied to global trade. We believe these occupancy improvements set the stage for rental rate growth in supply-constrained submarkets.”

Investment Activity

During the fourth quarter, AMB acquired 3.1 million square feet of distribution facilities in 16 buildings for a total expected investment of $200 million in metropolitan Paris, Amsterdam, Tokyo, Chicago and Minneapolis. The transactions bring the company’s full year acquisition activity to 7.6 million square feet in 64 buildings with a total expected investment of $695 million.

AMB stabilized three industrial development projects during the fourth quarter. The buildings, which are fully leased, comprise 1.2 million square feet for a total estimated investment of $47 million. During 2004, AMB’s development completions totaled 2.1 million square feet of new facilities with a total investment of $89 million.

New development and redevelopment starts in the quarter totaled approximately 1.6 million square feet in six projects in Europe and the United States with an estimated total investment of $151 million. The company began the highest level of new development in its history during 2004 with approximately 6.1 million square feet of starts with an estimated total investment at completion of $649 million. AMB’s industrial development and renovation pipeline now totals 30 projects of approximately 8.9 million square feet in North America, Europe and Asia. Total investment in the pipeline’s properties is estimated at $829 million. Deliveries are scheduled from the first quarter of 2005 through the first quarter of 2008.

AMB’s president, W. Blake Baird, commented, “Our acquisitions in the quarter advance our on- and near-airport presence in Europe, expand AMB’s existing customer offerings in Tokyo and build on our strong market position in Chicago. AMB’s capacity to create new distribution product has been well demonstrated by our development team in 2004. Today at more than $800 million, our development pipeline is the largest in our history. With over 60% of our development pipeline outside the United States, we are increasingly prepared to help our customers meet their global distribution facility needs.”

The quarter included sales of 14 buildings for a total disposition price of approximately $120 million, bringing the year’s disposition total to $200 million. In addition, the company generated net profits from its development-for-sale and contribution programs of $3.9 million in the quarter and $8.0 million in the full year 2004.

In other investment activity during the quarter, the company announced its planned acquisition of an approximately 41% interest in G. Acción S.A. de C.V. (G. Acción), one of Mexico’s largest public real estate companies. AMB began developing industrial real estate with G. Acción in Mexico in early 2002. Since then, AMB’s activity in Mexico City and Guadalajara has included approximately 3.1 million square feet of acquisition and development.

Private Capital Activity

AMB received approximately $336.5 million in private equity capital commitments during the fourth quarter in two separate investment funds. In what is believed to be the publicly traded REIT industry’s first open-end commingled fund, AMB raised $136.5 million of equity from 12 pension funds, foundations and private investors to form AMB Institutional Alliance Fund III. The fund’s primary investment focus is to acquire stabilized industrial facilities near key U.S. passenger and cargo airports, seaports and highway systems in major metropolitan markets.

During the fourth quarter, the company also formed AMB-SGP Mexico, LLC, a joint venture with GIC Real Estate Pte Ltd (GIC RE), a global investor in real estate on behalf of the Government of Singapore. The fund’s primary investment purpose is to invest in completed developments in targeted distribution markets in Mexico delivered by AMB and its local partner, G. Acción. GIC RE’s equity commitment to the fund is $200 million. AMB’s interest in the fund is approximately 20%.

Mr. Baird stated, “Expanding our private capital franchise to our global operating platform is an important element to improving our return on invested capital and increasing our ability to recognize value creation from our development business.”

Promotions and Addition of Company Officers

The company announced eight officer promotions effective January 1, 2005. Jay R. Cornforth, Martin J. Coyne, Rohn T. Grazer and Nina A. Tran have been promoted to senior vice president. R. Craig Blanchard, Drew Hess, Andrew G. Smith and Mohsen Vessali have been promoted to vice president.

Commenting on these promotions, Mr. Moghadam said, “AMB’s growth, expansion and pursuit of enduring excellence requires the sustained efforts of all our team members. This group of officers exemplifies the talent and dedication that will produce meaningful results for our customers and stockholders.”

In addition, vice presidents Elizabeth M. Wheeler, Amy A. Pallas, Scott Recknor, Robert B. Antrobius and Oliver J. Treneman have joined AMB offices in San Francisco, Los Angeles and Shanghai in renewal leasing and development roles.

Supplemental Earnings Measure

AMB reports funds from operations per fully diluted share and unit (FFOPS) in accordance with the standards established by NAREIT. Fourth quarter 2004 FFOPS was $0.62, compared with $0.59 in the same period of 2003. FFOPS for the full year ended December 31, 2004 was $2.30 compared with $2.13 for 2003. The quarterly and full year FFOPS results were at the low end of the company’s guidance of $0.62 to $0.68 per share and $2.30 to $2.36 per share respectively due primarily to delayed timing of anticipated profits associated with land sales. These land sales, with anticipated gains of approximately $0.05 per share, had previously been scheduled to occur by
year-end 2004 and are now expected to close during 2005.

Included in the footnotes to the company’s attached financial statements is a discussion of why management believes FFO is a useful supplemental measure of operating performance, ways in which investors might use FFO when assessing the company’s financial performance and FFO’s limitations as a measurement tool. A reconciliation from net income to funds from operations is provided in the attached tables and published in AMB’s quarterly supplemental analyst package, available on the company’s website at www.amb.com.

CONSOLIDATED STATEMENTS OF FUNDS FROM OPERATIONS ⁽²⁾
(dollars in thousands, except share data)

⁽¹⁾In the prior quarter, management restated AMB’s previously issued financial statements for the years ended December 31, 2003, 2002 and 2001 filed on Form 10-K/A and for the quarters ended March 31, 2004 and June 30, 2004 filed on Form 10-Q/A to reflect additional depreciation expense. The restatement affected the Company’s depreciation expense, net income and earnings per share for the prior periods. The net impact of the restatement of depreciation expense on earnings per share results reduced EPS by $0.02 from $1.43 to $1.41 for 2001; by $0.04 from $1.37 to $1.33 for 2002 and by $0.06 from $1.47 to $1.41 for 2003. This restatement of depreciation expense did not impact the Company’s previously reported funds from operations (FFO) per fully diluted share and unit as, in accordance with NAREIT’s FFO definition, the Company adds back real estate-related depreciation to calculate FFO. Please see the Company’s October 12, 2004 earnings press release, its annual report for the year ended December 31, 2003 in Amendment No. 2 on Form 10-K/A, its quarterly report for the quarter ended March 31, 2004 in Amendment No. 1 on Form 10-Q/A and its quarterly report for the quarter ended June 30, 2004 in Amendment No. 1 on Form 10-Q/A for more detail.

⁽²⁾Funds From Operations (“FFO”). The Company believes that net income, as defined by GAAP, is the most appropriate earnings measure. However, the Company considers funds from operations, or FFO, as defined by NAREIT, to be a useful supplemental measure of its operating performance. FFO is defined as net income, calculated in accordance with GAAP, less gains (or losses) from dispositions of real estate held for investment purposes and real estate-related depreciation, and adjustments to derive the Company’s pro rata share of FFO of consolidated and unconsolidated joint ventures. Further, the Company does not adjust FFO to eliminate the effects of non-recurring charges. The Company believes that FFO, as defined by NAREIT, is a meaningful supplemental measure of its operating performance because historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time, as reflected through depreciation and amortization expenses. However, since real estate values have historically risen or fallen with market and other conditions, many industry investors and analysts have considered presentation of operating results for real estate companies that use historical cost accounting to be insufficient. Thus, NAREIT created FFO as a supplemental measure of operating performance for real estate investment trusts that excludes historical cost depreciation and amortization, among other items, from net income, as defined by GAAP. The Company believes that the use of FFO, combined with the required GAAP presentations, has been beneficial in improving the understanding of operating results of real estate investment trusts among the investing public and making comparisons of operating results among such companies more meaningful. The Company considers FFO to be a useful measure for reviewing comparative operating and financial performance because, by excluding gains or losses related to sales of previously depreciated operating real estate assets and real estate depreciation and amortization, FFO can help the investing public compare the operating performance of a company’s real estate between periods or as compared to other companies. While FFO is a relevant and widely used measure of operating performance of real estate investment trusts, it does not

Page 9

represent cash flow from operations or net income as defined by GAAP and should not be considered as an alternative to those measures in evaluating the Company’s liquidity or operating performance. FFO also does not consider the costs associated with capital expenditures related to the Company’s real estate assets nor is FFO necessarily indicative of cash available to fund the Company’s future cash requirements. Further, the Company’s computation of FFO may not be comparable to FFO reported by other real estate investment trusts that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently than the Company does.

⁽³⁾Effective January 1, 2003, the Company discontinued its practice of deducting amortization of investments in leasehold interests from FFO as such an adjustment is not provided for in NAREIT’s FFO definition. As a result, FFO for the periods presented has been adjusted to reflect the changes.
