Exhibit 99.1

PROLOGIS AND AMB PROPERTY CORPORATION^® ANNOUNCE MERGER OF EQUALS

Creates the Pre-eminent Global Industrial Real Estate Company with Assets Owned and Under
Management of Approximately $46 Billion

Deepens Global Presence Including High-Growth Emerging Markets

Generates $80 Million of Estimated Annual Gross G&A Savings

Positions Combined Company for Sustainable Long-Term Growth and Value Creation

Companies Declare First Quarter Dividends

San Francisco and Denver, January 31, 2011 — AMB Property Corporation (NYSE: AMB) and ProLogis (NYSE: PLD) today announced a definitive agreement to combine through a merger of equals, creating the pre-eminent global owner, operator and developer of industrial real estate. Combined, the companies are expected to have a pro forma equity market capitalization of approximately $14 billion, a total market capitalization in excess of $24 billion, and gross assets owned and managed of approximately $46 billion.

Under the terms of the agreement, each ProLogis common share will be converted into 0.4464 of a newly issued AMB common share, and the combined company will be an UPREIT. The merger is subject to customary closing conditions, including receipt of approval of AMB and ProLogis shareholders. The parties currently expect the transaction to close during the second quarter of 2011. The all-stock merger is intended to be a tax-free transaction. Upon completion of the merger, the company will be named ProLogis and will trade under the ticker symbol PLD (NYSE).

The combined company brings together two of the most complementary customer franchises in real estate. The combined portfolio encompasses approximately 600 million square feet (55.7 million square meters) of modern distribution facilities located in key gateway markets and logistics corridors in 22 countries. Both companies have substantial portfolios in North America, Western Europe and Japan. ProLogis is well-established in the United Kingdom and Central and Eastern Europe, and AMB has a significant presence in China and Brazil.

“This merger is about two great companies coming together to create a stronger platform for sustainable value creation and growth. By joining forces, this merger will create a company positioned to be the leading global provider of logistics real estate — a Blue Chip REIT,” said Hamid R. Moghadam, AMB CEO. “The combined company will be a global player active on four continents. This enhanced platform will enable us to better serve the needs of multi-market customers and provide them with both existing world-class facilities and unmatched development capabilities. The combined company will also be well-positioned to create more opportunities and value for both our shareholders and fund investors.”

“This combination will help create the most efficient, effective industrial real estate organization with the best, most diverse talent. And, we have developed an achievable plan to put these companies together seamlessly,” added Walter C. Rakowich, ProLogis CEO. “The merger of these two leading industrial platforms will advance a number of priorities already underway at each company. These priorities include improving efficiency and reducing costs by better aligning our portfolios through the reduction of non-core assets and the recycling of capital into higher growth opportunities; increasing asset utilization by stabilizing the operating portfolio; leasing up the development portfolio; and monetizing the land bank.”

1

Leadership and Integration

Moghadam, AMB’s CEO, and Rakowich, ProLogis’ CEO, will serve as co-CEOs through December 31, 2012, at which time Rakowich will retire, and Moghadam will become sole CEO of the combined company. Moghadam also will be Chairman of the Board of the combined company and will be primarily responsible for shaping the company’s vision, strategy and private capital franchise. Rakowich will be principally responsible for operations, integration of the two platforms and optimizing the merger synergies. Until December 31, 2012, Rakowich also will serve as Chairman of the Board’s executive committee. William E. Sullivan, current ProLogis CFO, will continue to serve as CFO and will retire from ProLogis on December 31, 2012. During this period, Thomas S. Olinger, AMB’s current CFO, will be responsible for day-to-day integration activities and report to the CEOs; he will become the CFO of the combined company on December 31, 2012.

The board of directors of the combined company will consist of six board members designated by ProLogis and five board members designated by AMB. Irving F. “Bud” Lyons, III, an existing ProLogis Board member, will serve as Lead Independent Director.

Following the close of the transaction, the combined company’s corporate headquarters will be located in San Francisco, and the combined company’s operations headquarters will be located in Denver.

Accretion / Cost Savings

The transaction is expected to be immediately accretive, with approximately $80 million in estimated annual gross G&A savings, to be realized upon full integration, which is expected to occur over the 18-month period following the closing.

“We continue to see improvements in operating fundamentals across the globe with increasing occupancies and more positive net absorption,” said Rakowich. “As global demand picks up and trade activity returns to more robust levels, we believe our combined footprint and capabilities will allow us to better meet the real estate needs of our global customers and drive future growth.”

Private Capital

“Another benefit of this transaction is the companies’ complementary private capital businesses. Our combined company will be a market leader in the industrial real estate private capital sector, with a broad range of product offerings across the major markets including the Americas, Europe and Asia and across the risk/return spectrum,” said Moghadam. “The combined company will have a global team with deep experience in investment management spanning three decades.”

Ownership and Liquidity

On a pro forma basis, following the merger, former ProLogis equity holders will hold approximately 60 percent of the combined company’s equity, and former AMB equity holders will hold approximately 40 percent based on the exchange ratio. The combined entity is expected to provide shareholders with enhanced liquidity.

Pro forma Operations and Balance Sheet

Both companies have high-quality, well-located assets. On a pro forma basis, the combined company’s owned and managed assets, excluding development, were on average approximately 93 percent leased as of December 31, 2010, outperforming market averages over the last three years. The combined company is expected to have significant liquidity, a strong balance sheet and a well-staggered debt maturity profile provided by long-standing lending partners.

“Our goal is to create one of the strongest balance sheets in the REIT industry, which will provide greater financial flexibility to capture market opportunities across business cycles, improve cost of capital and help better manage currency risk,” said Sullivan.

2

Dividend Policy and Declaration

The timing of the pre-closing dividends of ProLogis and AMB will be coordinated such that, if one set of shareholders receives their dividend for a particular quarter prior to the closing of the merger, the other set of shareholders will also receive their dividend for such quarter prior to the closing of the merger.

Today, AMB announced that its Board has declared its first quarter dividend of $0.28 per common share, payable on February 28, 2011, to stockholders of record on February 14, 2011. Also, today, ProLogis announced that its Board has declared its first quarter dividend of $0.1125 per common share, payable on February 28, 2011, to stockholders of record on February 14, 2011.

Morgan Stanley acted as financial advisor to ProLogis, and Greenberg Traurig and Mayer Brown acted as legal advisors to ProLogis. J.P. Morgan Securities LLC acted as financial advisor to AMB, and Wachtell, Lipton, Rosen & Katz acted as legal advisor to AMB.

Reporting Definitions .. Core EBITDA, as Adjusted: The companies use core adjusted earnings before interest, tax, depreciation and amortization, impairment charges, gains or losses from the disposition of real estate investments, losses on early extinguishment of debt and derivatives contracts (including cash charges), and other non- cash charges (such as stock based compensation amortization, unrealized gains or losses on foreign currency and derivative activity) , including the companies share of these items (other than interest and current taxes) from their unconsolidated investees or ("Core EBITDA, as adjusted"), to measure both their operating performance and liquidity. The companies consider Core EBITDA, as adjusted to provide investors relevant and useful information because it permits investors to view income from operations on an unleveraged basis before the effects of tax, non-cash depreciation and amortization expense and other items(including stock-based compensation amortization and certain unrealized gains and losses), gains from the disposition of real estate investments, and other significant non-cash items. By excluding interest expense, adjusted EBITDA allows investors to measure the company's operating performance independent of their capital structure and indebtedness and, therefore, allows for a more meaningful comparison of its operating performance to that of other companies, both in the real estate industry and in other industries. The impairment charges were principally a result of the companies' changed intent with respect to the holding period of certain of its real estate properties and decreases in fair value due to increases in capitalization rates and deterioration in market conditions that adversely impacted values. Losses on the early extinguishment of debt and derivatives contracts generally included the costs of repurchasing debt securities. Although difficult to predict, these items may be recurring given the uncertainty of the current economic climate and its adverse effects on the real estate and financial markets. While not infrequent or unusual in nature, these items result from market fluctuations that can have inconsistent effects on each company's results of operations. The economics underlying these items reflect market and financing conditions in the short-term but can obscure each company's performance and the value of each company's long-term investment decisions and strategies. As a liquidity measure, the companies believe that Core EBITDA, as adjusted helps investors to analyze their ability to meet interest payment obligations and to make quarterly preferred share dividends and unit distributions. The companies believe that investors should consider Core EBITDA, as adjusted , in conjunction with net income (the primary measure of each company's performance) and the other required Generally Accepted Accounting Principles ("GAAP") measures of its performance and liquidity, to improve their understanding of each company's operating results and liquidity, and to make more meaningful comparisons of their performance against other companies. By using Core EBITDA, as adjusted, an investor is assessing the earnings generated by each company's operations, but not taking into account the eliminated expenses or gains incurred in connection with such operations. As a result, adjusted EBITDA has limitations as an analytical tool and should be used in conjunction with each company's required GAAP presentations. Core EBITDA, as adjusted does not reflect each company's historical cash expenditures or future cash requirements for working capital, capital expenditures distribution requirements or contractual commitments. Core EBITDA, as adjusted also does not reflect the cash required to make interest and principal payments on each company's outstanding debt. While Core EBITDA, as adjusted is a relevant and widely used measure of operating performance and liquidity, it does not represent net income or cash flow from operations as defined by GAAP and it should not be considered as an alternative to those indicators in evaluating operating performance or liquidity. Further, the companies' computation of Core EBITDA, as adjusted may not be comparable to EBITDA reported by other companies. The companies compensate for the limitations of Core EBITDA, as adjusted by providing investors with financial statements prepared according to U.S. GAAP, along with this detailed discussion of Core EBITDA, as adjusted and a reconciliation of Core EBITDA, as adjusted to net income (or loss), a U.S. GAAP measurement.

Definitions .. The following table reconciles Core EBITDA, as adjusted to estimated net earnings (loss) for the quarter ended December 31, 2010 (dollars in thousands):

Definitions .. Fixed charge coverage: Fixed charge coverage is defined as Core EBITDA, as adjusted divided by fixed charges. Fixed charges consist of interest expense less finance costs and debt premiums, from continuing and discontinued operations, plus capitalized interest, preferred unit distributions and preferred stock dividends. The companies use fixed charge coverage to measure liquidity. The companies believe fixed charge coverage is relevant and useful to investors because it permits fixed income investors to measure the company's ability to meet its interest payments on outstanding debt, make distributions to its preferred unitholders and pay dividends to its preferred shareholders. The company's computation of fixed charge coverage may not be comparable to fixed charge coverage reported by other companies. The following table details the calculation of fixed charges for three months ended December 31, 2010 (dollars in thousands):
