FOR IMMEDIATE RELEASE

AMB PROPERTY CORPORATION^® ANNOUNCES FIRST QUARTER 2009 RESULTS

SAN FRANCISCO, April 28, 2009 — AMB Property Corporation^® (NYSE: AMB), a leading owner, operator and developer of industrial real estate, today reported results for the first quarter 2009. Funds from operations per fully diluted share and unit (“FFOPS”) was a $1.00 loss for the first quarter of 2009, as compared to $0.65 for the same quarter in 2008.

Consistent with its previous announcement, the company recognized non-cash impairment charges in the first quarter of 2009, related to valuation of its development and operating assets and land holdings, totaling approximately $182 million. The impairment charges are primarily attributed to changes in leasing and valuation assumptions. Excluding the impact of the impairments, FFOPS would have been $0.77 for the first quarter of 2009.

Net income available to common stockholders per fully diluted share (“EPS”) for the first quarter of 2009 was a loss of $1.24, as compared to $0.39 for the same quarter in 2008. The loss was attributable to impairment charges that the company incurred in the quarter.

Financing Activities

As previously announced, AMB completed the issuance and sale of 47.4 million shares of its common stock in a public offering at a price of $12.15 per share, generating $553 million in net proceeds to further strengthen the company’s balance sheet. The proceeds from the offering were used to reduce borrowings under the company’s unsecured credit facilities.

In addition to the reduction of its credit facilities, AMB has repaid, refinanced or extended approximately $751 million of its debt during the first quarter of 2009, demonstrating the company’s continued ability to access the credit markets. AMB’s share of total debt was reduced by approximately $787 million during the quarter, and at March 31, 2009, AMB’s share of total debt to share of total assets was 43.6 percent, as compared to 51.1 percent at the end of the fourth quarter 2008.

Contributions and Dispositions

Year-to-date the company has completed contributions and sales of approximately $391 million.

During the first quarter, the company completed contributions and sales totaling approximately $304 million, with gains of approximately $52 million, consisting of the following:

§

The contribution of one asset to AMB Japan Fund I and the sale of five development properties and a land parcel in the U.S. for an aggregate price of approximately $243 million, with a gain of more than $33 million and an average development margin of 20.6 percent; and

§

The sale of eight properties from its operating portfolio in the U.S. for an aggregate sales price of approximately $62 million, with a gain of approximately $19 million.

Subsequent to quarter end, the company completed sales in its development and operating portfolio totaling approximately $87 million, including two development properties for an aggregate sales price of approximately $50 million, and two properties from its operating portfolio for an aggregate sales price of approximately $37 million. The year-to-date stabilized capitalization rate for its asset sales in the U.S. was approximately 8.5 percent.

The company has other assets in its operating and development portfolios that are currently under contract for sale or scheduled for contribution in 2009, subject to certain conditions, for an aggregate sales price of approximately $219 million. The company also has approximately $51 million of operating and development properties for sale that are currently under non-binding letters of intent.

“We have made significant progress executing on our deleveraging objectives thus far in 2009. The company is even better positioned to weather this downturn with the completion of our follow-on offering, debt repayments, refinancings and dispositions. We have more than enough capacity to meet our needs into 2013 and have the ability to grow our business when compelling opportunities present themselves,” said Hamid R. Moghadam, AMB’s chairman & CEO.

Investment Activity

The company commenced two previously committed build-to-suit developments in Paris, France and Monterrey, Mexico, totaling 464,000 square feet (43,100 square meters) during the quarter, with a total estimated investment of $29 million.

AMB’s global development pipeline at quarter end, which included investments held through unconsolidated joint ventures, totaled approximately 11.8 million square feet (1.1 million square meters) scheduled for delivery through 2010, with an estimated total investment of $983.6 million before the recognition of the impairment charges. The company’s share of the remaining cash to fund the completion of its development pipeline is projected to be $135 million. The development pipeline was approximately 31 percent leased as of March 31, 2009, with approximately 7 million square feet (650,800 square meters) of leasing remaining in order to stabilize the pipeline.

Leasing Activity

During the first quarter of 2009, the company leased more than 1.0 million square feet (94,500 square meters) of its development pipeline. In its global operating portfolio, AMB leased approximately 5.6 million square feet (519,000 square meters) in the first quarter.

“Leasing activity has held up well, particularly in light of current economic conditions. First quarter leasing activity in our development pipeline surpasses the development leasing results achieved in the first quarters of 2007 and 2008. While we’re pleased with our level of development leasing in the quarter, we do not expect to sustain our normal run rate for the next couple of quarters due to slow demand for new space. Leasing in our operating portfolio is in-line with our forecast,” said Tom Olinger, AMB’s chief financial officer.

Owned and Managed Portfolio Operating Results

AMB’s operating portfolio was 92.2 percent occupied at March 31, 2009, with an average occupancy rate of 93.1 percent for the first quarter of 2009. Cash basis same store net operating income (“SS NOI”), without the effects of lease termination fees, decreased 1.1 percent in the first quarter compared with the same period in 2008, driven primarily by lower average same store occupancies. Average rent change on renewals and rollovers in AMB’s operating portfolio was flat for the quarter and 2.2 percent for the trailing four quarters ended March 31, 2009.

2009 FFO Guidance

The company maintains its previous full-year 2009 FFO guidance, without recognition of gains from development activities or non-cash impairment charges, of $1.41 to $1.49 per share. The full-year EPS guidance is a loss of $0.58 to $0.66 per share. Expected results have been adjusted for the estimated impact of the equity offering.

Annual Meeting of Stockholders

The Annual Meeting of Stockholders will be held on Thursday, May 7, 2009 at 2:00 PM PDT / 5:00 PM EDT. Stockholders are invited to attend the meeting at the company’s global headquarters located at Pier 1, Bay 1, in San Francisco, Calif. The proxy statement, Annual Report to Stockholders, voting materials and meeting information were mailed on or about March 25, 2009. Stockholders who are unable to attend the annual meeting may listen to a live webcast through a link on the company website at www.amb.com in the Investor Relations section. A replay will be available after 5:00 PM PDT / 8:00 PM EDT on Thursday, May 7, 2009, until 5:00 PM PDT / 8:00 PM EDT on Monday, June 8, 2009.

Supplemental Earnings Measure

Included in the footnotes to the company’s attached financial statements is a discussion of why management believes FFO, FFOPS and FFO, excluding impairment charges (the “FFO Measures”) are useful supplemental measures of operating performance, ways in which investors might use the FFO Measures when assessing the company’s financial performance and the FFO Measures’ limitations as a measurement tool. Reconciliation from net income to the FFO Measures are provided in the attached tables and published in the company’s quarterly supplemental analyst package, available on the company’s website at www.amb.com.

The company believes that net income, as defined by GAAP, is the most appropriate earnings measure. However, the company considers cash-basis same store net operating income (“SS NOI”) to be a useful supplemental measure of its operating performance. Properties that are considered part of the same store pool include all properties that were owned as of the end of both the current and prior year reporting periods and exclude development properties for both the current and prior reporting periods. The same store pool is set annually and excludes properties purchased and developments stabilized after December 31, 2007. In deriving SS NOI, the company defines NOI as rental revenues, including reimbursements, less property operating expenses, both of which are calculated in accordance with GAAP. Property operating expenses exclude depreciation, amortization, general and administrative expenses and interest expense. The company defines SS NOI to also exclude straight-line rents and amortization of lease intangibles. The company

		Page 4

considers SS NOI to be an appropriate and useful supplemental performance measure because it reflects the operating performance of the real estate portfolio excluding effects of non-cash adjustments and provides a better measure of actual cash basis rental growth for a year-over-year comparison. In addition, the company believes that SS NOI helps the investing public compare the company’s operating performance with that of other companies. While SS NOI is a relevant and widely used measure of operating performance of real estate investment trusts, it does not 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. SS NOI also does not reflect general and administrative expenses, interest expense, depreciation and amortization costs, capital expenditures and leasing costs, or trends in development and construction activities that could materially impact its results from operations. Further, the company’s computation of SS NOI may not be comparable to that of other real estate companies, as they may use different methodologies for calculating SS NOI. Reconciliation from net income to SS NOI is provided in the attached tables and published in the company’s quarterly supplemental analyst package, available on the company’s website at www.amb.com.

AMB includes the gains from development, including those from value-added conversion projects, before depreciation recapture, as a component of FFO. AMB believes that value-added conversion dispositions are in substance land sales and as such should be included in FFO, consistent with the real estate investment trust industry’s long standing practice to include gains on the sale of land in FFO. However, AMB’s interpretation of FFO or FFOPS may not be consistent with the views of others in the real estate investment trust industry, who may consider it to be a divergence from the NAREIT definition, and may not be comparable to FFO or FFOPS reported by other real estate investment trusts that interpret the current NAREIT definition differently than AMB does. In connection with the formation of a joint venture, AMB may warehouse assets that are acquired with the intent to contribute these assets to the newly formed venture. Some of the properties held for contribution may, under certain circumstances, be required to be depreciated under U.S. GAAP. If this circumstance arises, AMB intends to include in its calculation of FFO gains or losses related to the contribution of previously depreciated real estate to joint ventures. Although such a change, if instituted, will be a departure from the current NAREIT definition, AMB believes such calculation of FFO will better reflect the value created as a result of the contributions. To date, AMB has not included gains or losses from the contribution of previously depreciated warehoused assets in FFO.

In addition to presenting FFO as described above, AMB presents FFO, excluding impairment charges. AMB calculates FFO, excluding impairment charges, as FFO less impairment charges and adjustments to derive AMB’s share of impairment charges from consolidated and unconsolidated joint ventures. To the extent that the book value of a land parcel or development asset exceeded the fair market value of a property, based on its intended holding period, a non-cash impairment charge was recognized for the shortfall. The impairment charges were principally a result of increases in estimated capitalization rates and deterioration in market conditions that adversely impacted values. Although difficult to predict, these charges may be recurring given the uncertainty of the current economic climate and its adverse effects on the real estate markets. While not infrequent or unusual in nature, these charges are subject to market fluctuations that can have inconsistent effects on AMB’s results of operations. The economics underlying these charges reflect market conditions in the short-term but can obscure the value of AMB’s long-term investment decisions and strategies. Management believes

Page 8

FFO, excluding impairment charges, is significant and useful to both it and its investors because it more appropriately reflects the value and strength of AMB’s business model and its potential performance isolated from the volatility of the current economic environment. However, in addition to the limitations of FFO Measures generally discussed below, FFO, excluding impairment charges, does not present a comprehensive measure of AMB’s financial condition and operating performance. This measure is a modification of the NAREIT definition of FFO and should not be considered a replacement of FFO as AMB defines it or used as an alternative to net income or cash as defined by U.S. GAAP.

AMB believes that the FFO Measures are meaningful supplemental measures of its operating performance because historical cost accounting for real estate assets in accordance with U.S. 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, the FFO Measures are supplemental measures of operating performance for real estate investment trusts that exclude historical cost depreciation and amortization, among other items, from net income available to common stockholders, as defined by U.S. GAAP. AMB believes that the use of the FFO Measures, combined with the required U.S. 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. AMB considers the FFO Measures to be useful measures 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, the FFO Measures 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 and FFOPS are relevant and widely used measures of operating performance of real estate investment trusts, the FFO Measures do not represent cash flow from operations or net income as defined by U.S. GAAP and should not be considered as alternatives to those measures in evaluating AMB’s liquidity or operating performance. The FFO Measures also do not consider the costs associated with capital expenditures related to AMB’s real estate assets nor are the FFO Measures necessarily indicative of cash available to fund AMB’s future cash requirements. Management compensates for the limitations of the FFO Measures by providing investors with financial statements prepared according to U.S. GAAP, along with this detailed discussion of the FFO Measures and a reconciliation of the FFO Measures to net income available to common stockholders, a U.S. GAAP measurement.

See Consolidated Statements of Funds from Operations for a reconciliation of FFO from net income available to common stockholders.
