DOCUMENTS INCORPORATED BY REFERENCE

Portions of Part III of this report are incorporated by reference to the registrant’s definitive proxy statement for the 2016 annual meeting of its stockholders or will be provided in an amendment filed on Form 10-K/A.

EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 2015, of Prologis, Inc. and Prologis, L.P. Unless stated otherwise or the context otherwise requires, references to “Prologis, Inc.” or the “Parent” mean Prologis, Inc. and its consolidated subsidiaries; and references to “Prologis, L.P.” or the “Operating Partnership” mean Prologis, L.P., and its consolidated subsidiaries. The terms “the Company,” “Prologis,” “we,” “our” or “us” means Prologis, Inc. and the Operating Partnership collectively.

Prologis, Inc. is a real estate investment trust (a “REIT”) and the general partner of the Operating Partnership. At December 31, 2015, Prologis, Inc. owned an approximate 97.12% common general partnership interest in the Operating Partnership and 100% of the preferred units in the Operating Partnership. The remaining approximate 2.88% common limited partnership interests are owned by nonaffiliated investors and certain current and former directors and officers of Prologis, Inc. As the sole general partner of the Operating Partnership, Prologis, Inc. has complete responsibility and discretion in the day-to-day management and control of the Operating Partnership.

We operate Prologis, Inc. and the Operating Partnership as one enterprise. The management of Prologis, Inc. consists of the same members as the management of the Operating Partnership. These members are officers of Prologis, Inc. and employees of the Operating Partnership or one of its subsidiaries. As general partner with control of the Operating Partnership, Prologis, Inc. consolidates the Operating Partnership for financial reporting purposes. Because the only significant asset of Prologis, Inc. is its investment in the Operating Partnership, the assets and liabilities of Prologis, Inc. and the Operating Partnership are the same on their respective financial statements.

We believe combining the annual reports on Form 10-K of Prologis, Inc. and the Operating Partnership into this single report results in the following benefits:

It is important to understand the few differences between Prologis, Inc. and the Operating Partnership in the context of how we operate the Company. Prologis, Inc. does not conduct business itself, other than acting as the sole general partner of the Operating Partnership and issuing public equity from time to time. Prologis, Inc. itself does not incur any indebtedness, but it guarantees the unsecured debt of the Operating Partnership. The Operating Partnership holds substantially all the assets of the business, directly or indirectly, and holds the ownership interests in the Company’s investment in certain entities. The Operating Partnership conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from equity issuances by Prologis, Inc., which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates capital required by the business through the Operating Partnership’s operations, incurrence of indebtedness and issuance of partnership units to third parties.

Noncontrolling interests, stockholders’ equity and partners’ capital are the main areas of difference between the consolidated financial statements of Prologis, Inc. and those of the Operating Partnership. The noncontrolling interests in the Operating Partnership’s consolidated financial statements include the interests in consolidated entities not owned by the Operating Partnership. The noncontrolling interests in Prologis, Inc.’s consolidated financial statements include the same noncontrolling interests at the Operating Partnership level, as well as the common limited partnership interests in the Operating Partnership, not owned by Prologis, Inc., which are accounted for as partners’ capital by the Operating Partnership.

To highlight the differences between Prologis, Inc. and the Operating Partnership, separate sections in this report, as applicable, individually discuss Prologis, Inc. and the Operating Partnership, including separate financial statements and separate Exhibit 31 and 32 certifications. In the sections that combine disclosure of Prologis, Inc. and the Operating Partnership, this report refers to actions or holdings as being actions or holdings of Prologis.

The statements in this report that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are based on current expectations, estimates and projections about the industry and markets in which we operate as well as management’s beliefs and assumptions. Such statements involve uncertainties that could significantly impact our financial results. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” and “estimates” including variations of such words and similar expressions are intended to identify such forward-looking statements, which generally are not historical in nature. All statements that address operating performance, events or developments that we expect or anticipate will occur in the future — including statements relating to rent and occupancy growth, development activity and changes in sales or contribution volume of properties, disposition activity, general conditions in the geographic areas where we operate, our debt, capital structure and financial position, our ability to form new co-investment ventures and the availability of capital in existing or new co-investment ventures — are forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Although we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be attained, and therefore actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements.

Risk Factors in this report. We undertake no duty to update any forward-looking statements appearing in this report except as may be required by law.

PART I

ITEM 1. Business

The Company

We are the global leader in logistics real estate, focused on high-barrier, high-growth markets across the Americas, Europe and Asia. At December 31, 2015, we owned or had investments in, on a wholly owned basis or through co-investment ventures, properties and development projects expected to total approximately 669 million square feet (62 million square meters) in 20 countries. We lease modern distribution facilities to a diverse base of more than 5,200 customers across two major categories: business-to-business and retail/online fulfillment. For business-to-business enterprises, our buildings serve a variety of sectors, including automotive, transportation, pharmaceuticals and general consumer goods. In the area of retail/online fulfillment, our state-of-the-art logistics facilities foster the seamless flow of goods around the world.

Details of the 669 million square feet at December 31, 2015 was as follows (dollars and square feet in millions):

Our operating portfolio includes stabilized industrial properties in our owned and managed portfolio. A developed property moves into the operating portfolio when it meets stabilization. The property is considered stabilized when a development project has been completed for one year or is at least 90% occupied whichever occurs first. Our other real estate properties include properties in which we have an ownership interest but do not manage, and other properties we own, such as value-added

3

properties and assets held for sale to third parties. Value-added properties are those which are expected to be repurposed or redeveloped to a higher and better use. They also include newly acquired properties that present opportunities to create greater value.

Prologis, Inc. began operating as a fully integrated real estate company in 1997 and elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”). We believe the current organization and method of operation will enable Prologis, Inc. to maintain its status as a REIT. The Operating Partnership also was formed in 1997.

Our global corporate headquarters are at Pier 1, Bay 1, San Francisco, California 94111, and our other principal offices are in Amsterdam, Denver, Luxembourg, Mexico City, Sao Paulo, Shanghai, Singapore and Tokyo.

Our Internet address is www.prologis.com. All reports required to be filed with the Securities and Exchange Commission (“SEC”) are available and can be accessed free of charge through the Investor Relations section of our website after we electronically submit material to the SEC. The common stock of Prologis, Inc. is listed on the New York Stock Exchange (“NYSE”) under the ticker “PLD” and is a component of the Standard & Poor’s (“S&P”) 500.

Investment Strategy

Our investment strategy focuses on providing high-quality distribution facilities to customers whose businesses are tied to consumption and global trade and as such depend on the efficient movement of goods through the supply chain. We have a significant worldwide presence of $51.5 billion of real estate assets in our owned and managed portfolio which spans 20 countries on four continents. We focus our investments in large population centers with high per-capita consumption rates located near major airports, seaports and rail and highway systems. We classify our properties into two main market categories: global and regional. Global markets comprise approximately 30 of the largest markets tied to global trade and consumption. Regional markets benefit from large population centers but typically are not as tied to the global supply chain; instead, they serve local consumption and are less supply constrained.

We intend to hold primarily Class-A product in global and regional markets. At December 31, 2015, global and regional markets represented approximately 89% and 11%, respectively, of our owned and managed portfolio (based on our share, as determined by our ownership percentage for consolidated and unconsolidated entities, of the properties’ gross book value).

We have deep knowledge of our local markets, extensive construction expertise and a demonstrated commitment to sustainable design across our portfolio. We are supported by a diverse customer base and our relationships with multinational corporations bring us repeat business across our global portfolio. See below for information on our customers. For more detail on our properties, see Item 2. Properties.

Both macroeconomics and demographics are important drivers of our business; these drivers include population growth, consumption and rising affluence. In the developed markets of the United States (or “U.S.”), Europe and Japan, the reconfiguration of supply chains, which is strongly influenced by e-commerce trends, as well as the operational efficiencies that can be realized from our modern logistics facilities, are key factors. In emerging markets, such as Brazil, China and Mexico, new affluence and the rise of the consumer classes together have prompted demand as supply chains are constructed. Taken together, logistics real estate markets benefit from economic growth, as well as from the modernization of supply chains around the world.

In addition to our wholly owned investments we also have investments in a variety of ventures. We co-invest with partners and investors in entities that own multiple properties. We refer to these entities as co-investment ventures (consolidated or unconsolidated).

Business Strategy and Operating Segments

Our business comprises two operating segments: Real Estate Operations and Strategic Capital.

Real Estate Operations

Rental Operations. Rental operations is the largest segment and contributed approximately 90% of our revenues, earnings and funds from operations in 2015 (see below for our definition of funds from operations and a complete reconciliation to net earnings in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations). We collect rent from our customers through operating leases, including reimbursements for the majority of our property operating costs. We expect to generate long-term internal growth by maintaining high occupancy rates, controlling expenses and increasing rents. Our rental revenue is diversified by customer segment and geography. We believe our property management, leasing and maintenance teams, together with our capital expenditure, energy and risk management programs, create cost efficiencies that allow us to capitalize on the economies of scale inherent in owning, operating and growing a global portfolio.

Capital Deployment. Capital deployment includes the development, redevelopment and acquisition of industrial properties to increase rental income and therefore is reported with rental operations. We primarily deploy capital in global and regional markets to serve our customers’ requirements. We capitalize on the following: (i) our land bank, (ii) the development expertise of our local teams, (iii) our customer relationships, and (iv) the demand for high-quality distribution facilities. We aim to increase our rental revenue and our net asset value by leasing newly developed space and acquiring operating properties. We develop properties for long-term hold, for contribution to our co-investment ventures and, occasionally, for sale to third parties. In 2015, we stabilized $1.6 billion of development projects with an estimated gross margin of 32%, creating $515 million in value for Prologis.

Strategic Capital

Real estate is a capital intensive business that requires growth capital. We manage third-party capital on behalf of the world’s largest institutional partners in order to grow our business, provide incremental revenues, and align our assets and liabilities in local currencies thereby mitigating foreign currency risk associated with our international investments. We tailor logistics portfolios to meet our partners’ specific needs, with a focus on long-term ventures and open-ended funds. We also access alternative sources of equity through the publicly traded vehicles Nippon Prologis REIT, Inc. (“NPR”) and FIBRA Prologis. We hold a significant ownership interest in these ventures, aligning our interests with those of our partners. We generate strategic capital revenues from our unconsolidated ventures through asset management and property management services and we earn additional revenues by providing leasing, acquisition, construction, development, financing and disposition services. At December 31, 2015, we managed 276.5 million square feet of operating properties in nine unconsolidated co-investment ventures. For more detail of our co-investment ventures, see Item 2. Properties. Depending on the structure of the venture and the returns provided to our partners, we also earn revenues through incentive fees during the life of a venture or upon liquidation (called “promotes”). In 2015, this segment contributed approximately 10% of our revenues, earnings and our funds from operations. We plan to grow this business generally through our existing ventures.

Competition

Competitively priced distribution space could impact our occupancy rates and have an adverse effect on how much rent we can charge, which in turn could affect both of our operating segments. We may face competition with regard to our capital deployment activities, including local, regional and national operators or developers. We also face competition from investment managers for institutional capital within our strategic capital business.

We believe we have competitive advantages due to our:

Customers

Our broad customer base represents a spectrum of international, national, regional and local distribution users. At December 31, 2015, in Real Estate Operations, we had more than 4,600 customers occupying 338.3 million square feet of distribution space. On an owned and managed basis, we had more than 5,200 customers occupying 614.7 million square feet of distribution space.

In Strategic Capital, we view our partners and investors as our customers. At December 31, 2015, in our private ventures, we partnered with approximately 100 investors, several of which invest in multiple ventures.

The following table details our top 25 customers at December 31, 2015 (square feet in thousands):

Employees

The following table summarizes our global employee base at December 31, 2015:

We believe we have good relationships with our employees. Prologis employees are not organized under collective bargaining agreements, although some employees in Europe are represented by statutory Works Councils and as such they benefit from applicable labor agreements.

Code of Ethics and Business Conduct

We maintain a Code of Ethics and Business Conduct applicable to our board of directors (the “Board”) and all of our officers and employees, including the principal executive officer, the principal financial officer and the principal accounting officer, or other people performing similar functions. A copy of our Code of Ethics and Business Conduct is available on our website, www.prologis.com. In addition to being accessible through our website, copies of our Code of Ethics and Business Conduct can be obtained, free of charge, upon written request to Investor Relations, Pier 1, Bay 1, San Francisco, California 94111. Any amendments to or waivers of our Code of Ethics and Business Conduct that apply to the principal executive officer, the principal financial officer, or the principal accounting officer, or other people performing similar functions, and that relate to any matter enumerated in Item 406(b) of Regulation S-K, will be disclosed on our website.

Environmental Matters

We are exposed to various environmental risks that may result in unanticipated losses and affect our operating results and financial condition. Either the previous owners or we have conducted environmental reviews on a majority of the properties we have acquired, including land. While some of these assessments have led to further investigation and sampling, none of the environmental assessments has revealed an environmental liability that we believe would have a material adverse effect on our business, financial condition or results of operations. See Item 1A. Risk Factors and Note 17 to the Consolidated Financial Statements in Item 8.

Insurance Coverage

We carry insurance coverage on our properties. We determine the type of coverage and the policy specifications and limits based on what we deem to be the risks associated with our ownership of properties and our business operations in specific markets. Such coverage typically includes property damage and rental loss insurance resulting from such perils as fire, windstorm, flood, earthquake and terrorism; commercial general liability insurance; and environmental insurance. Insurance is maintained through a combination of commercial insurance, self-insurance and a wholly-owned captive insurance entity. The costs to insure our properties are primarily covered through reimbursements from our customers. We believe that our insurance coverage contains policy specifications and insured limits that are customary for similar properties, business activities and markets and we believe our properties are adequately insured. See further discussion in Item 1A. Risk Factors.

ITEM 1A. Risk Factors

Our operations and structure involve various risks that could adversely affect our business and financial condition, including but not limited to, our financial position, results of operations, cash flow, ability to make distributions and payments to security holders and the market value of our securities. These risks relate to our consolidated company as well as our investments in unconsolidated entities and include among others, (i) general risks; (ii) risks related to our business; (iii) risks related to financing and capital and (iv) income tax risks.

General Risks

As a global company, we are subject to social, political and economic risks of doing business in many countries.

We conduct a significant portion of our business and employ a substantial number of people outside of the U.S. During 2015, we generated approximately $335.3 million or 15.3% of our revenue from operations outside the U.S. Circumstances and developments related to international operations that could negatively affect us include, but are not limited to, the following factors:

6

In addition, we may be impacted by the ability of our non-U.S. subsidiaries to dividend or otherwise transfer cash among our subsidiaries, including transfers of cash to pay interest and principal on our debt, due to currency exchange control regulations, transfer pricing regulations and potentially adverse tax consequences, among other factors.

Disruptions in the global capital and credit markets may adversely affect our operating results and financial condition.

To the extent there is turmoil in the global financial markets, this turmoil has the potential to adversely affect (i) the value of our properties; (ii) the availability or the terms of financing that we have or may anticipate utilizing; (iii) our ability to make principal and interest payments on, or refinance any outstanding debt when due; and (iv) the ability of our customers to enter into new leasing transactions or satisfy rental payments under existing leases. Disruptions in the capital and credit markets may also adversely affect our ability to make distributions and payments to our security holders and the market price of our securities.

Our business and operations could suffer in the event of system failures or cyber security attacks.

Despite system redundancy, the implementation of security measures and the existence of a disaster recovery plan for our internal information technology systems, our systems are vulnerable to damages from any number of sources, including energy blackouts, natural disasters, terrorism, war, telecommunication failures and cyber security attacks, such as computer viruses or unauthorized access. Any system failure or accident that causes interruptions in our operations could result in a material disruption to our business. We may also incur additional costs to remedy damages caused by such disruptions. Any compromise of our security could result in a violation of applicable privacy and other laws, unauthorized access to information of ours and others, significant legal and financial exposure, damage to our reputation, loss or misuse of the information and a loss of confidence in our security measures, which could harm our business.

Risks associated with our dependence on key personnel.

We depend on the deep industry knowledge and the efforts of our executive officers and other key employees. From time to time, our personnel and their roles may change. While we believe that we are able to retain our key talent and find suitable employees to meet our personnel needs, the loss of key personnel, any change in their roles or the limitation of their availability could adversely affect our business. If we are unable to continue to attract and retain our executive officers, or if compensation costs required to attract and retain key employees become more expensive, our performance and competitive position could be materially adversely affected.

Our business could be adversely impacted if we have deficiencies in our disclosure controls and procedures or internal control over financial reporting.

The design and effectiveness of our disclosure controls and procedures and internal control over financial reporting may not prevent all errors, misstatements or misrepresentations. While management continually reviews the effectiveness of our disclosure controls and procedures and internal control over financial reporting, there can be no guarantee that our internal control over financial reporting will be effective in accomplishing all control objectives all of the time. Deficiencies, including any material weakness, in our internal control over financial reporting that may occur in the future could result in misstatements or restatements of our financial statements or a decline in the price of our securities.

The depreciation in the value of the foreign currency in countries where we have a significant investment may adversely affect our results of operations and financial position.

We pursue growth opportunities in international markets where the U.S. dollar is not the functional currency. At December 31, 2015, approximately $6.3 billion or 20.1% of our total assets are invested in a currency other than the U.S. dollar, primarily the British pound sterling, euro and Japanese yen. As a result, we are subject to foreign currency risk due to potential fluctuations in exchange rates between foreign currencies and the U.S. dollar. A significant change in the value of the foreign currency of one or more countries where we have a significant investment may have a material adverse effect on our business and, in particular, our U.S. dollar reported financial position and results of operations and debt covenant ratios. Although we attempt to mitigate adverse effects by borrowing under debt agreements denominated in foreign currencies and using derivative contracts, there can be no assurance that those attempts to mitigate foreign currency risk will be successful.

Our hedging of foreign currency and interest rate risk may not effectively limit our exposure to other risks.

Hedging arrangements involve risks, such as the risk of fluctuation in the relative value of the foreign currency or interest rates and the risk that counterparties may fail to honor their obligations under these arrangements. The funds required to settle such arrangements could be significant depending on the stability and movement of the hedged foreign currency or the size of the underlying financing and the applicable interest rates at the time of the breakage. The failure to hedge effectively against exchange rate changes or interest rate changes may adversely affect our business.

Compliance or failure to comply with regulatory requirements could result in substantial costs.

We are required to comply with many regulations in different countries, including (but not limited to) the Foreign Corrupt Practices Act, the United Kingdom Bribery Act and similar laws and regulations. Our properties are also subject to various federal, state and local regulatory requirements, such as the Americans with Disabilities Act and state and local fire and life-safety requirements. Noncompliance could result in the imposition of governmental fines or the award of damages to private litigants. While we believe that we are currently in material compliance with these regulatory requirements, the requirements may change or new requirements may be imposed that could require significant unanticipated expenditures by us. If we are required to make unanticipated expenditures to comply with these regulations we may be adversely affected.

Risks Related to our Business

Real estate investments are not as liquid as certain other types of assets, which may reduce economic returns to investors.

Real estate investments are not as liquid as certain other types of investments and this lack of liquidity may limit our ability to react promptly to changes in economic or other conditions. Significant expenditures associated with real estate investments, such as secured mortgage payments, real estate taxes and maintenance costs, are generally not reduced when circumstances cause a reduction in income from the investments. As a REIT, under the Internal Revenue Code, we are only able to hold property for sale in the ordinary course of business through taxable REIT subsidiaries in order to not incur punitive taxation on any tax gain from the sale of such property. We may dispose of certain properties that have been held for investment to generate liquidity. If we do not satisfy certain safe harbors or we believe there is too much risk of incurring the punitive tax on any tax gain from the sale, we may not pursue such sales.

7

We may decide to sell properties to certain of our unconsolidated co-investment ventures or third parties to generate proceeds to fund our capital deployment activities. Our ability to sell properties on advantageous terms is affected by: (i) competition from other owners of properties that are trying to dispose of their properties; (ii) market conditions, including the capitalization rates applicable to our properties; and (iii) other factors beyond our control. If our competitors sell assets similar to assets we intend to divest in the same markets or at valuations below our valuations for comparable assets, we may be unable to divest our assets at favorable pricing or at all. The unconsolidated co-investment venture or third party who might acquire our properties may need to have access to debt and equity capital, in the private and public markets, in order to acquire properties from us. Should they have limited or no access to capital on favorable terms, then dispositions could be delayed.

If we do not have sufficient cash available to us through our operations, sales or contributions of properties or available credit facilities to continue operating our business as usual, we may need to find alternative ways to increase our liquidity. Such alternatives may include, without limitation, divesting ourselves of properties, whether or not they otherwise meet our strategic objectives to keep in the long term, at less than optimal terms, incurring debt, entering into leases with new customers at lower rental rates or less than optimal terms or entering into lease renewals with our existing customers without an increase in rental rates. There can be no assurance, however, that such alternative ways to increase our liquidity will be available to us. Additionally, taking such measures to increase our liquidity may adversely affect our business, and in particular, our distributable cash flow and debt covenants.

Our investments are concentrated in the industrial distribution sector and our business would be adversely affected by an economic downturn in that sector.

Our investments in real estate assets are primarily concentrated in the industrial distribution sector. This concentration may expose us to the risk of economic downturns in this sector to a greater extent than if our business activities were more diversified.

General economic conditions and other events or occurrences that affect areas in which our properties are geographically concentrated, may impact financial results.

We are exposed to general economic conditions, local, regional, national and international economic conditions and other events and occurrences that affect the markets in which we own properties. Our operating performance is further impacted by the economic conditions of the specific markets in which we have concentrations of properties.

At December 31, 2015, approximately 31.9% of our consolidated operating properties or $7.7 billion (based on gross book value, or investment before depreciation) are located in California, which represented 25.1% of the aggregate square footage of our operating properties and 31.0% of our net operating income. Our revenue from, and the value of, our properties located in California may be affected by local real estate conditions (such as an oversupply of or reduced demand for industrial properties) and the local economic climate. Business layoffs, downsizing, industry slowdowns, changing demographics and other factors may adversely impact California’s economic climate. Because of the number of properties we have located in California, a downturn in California’s economy or real estate conditions could adversely affect our business.  

In addition to California, we also have significant holdings (defined as more than 3.0% of total investment before depreciation) in operating properties in certain global and regional markets located in Atlanta, Central and Eastern Pennsylvania, Chicago, Dallas/Fort Worth, New Jersey/New York City, and South Florida. Our operating performance could be adversely affected if conditions become less favorable in any of the markets in which we have a concentration of properties. Conditions such as an oversupply of distribution space or a reduction in demand for distribution space, among other factors, may impact operating conditions. Any material oversupply of distribution space or material reduction in demand for distribution space could adversely affect our overall business.  

In addition, our owned and managed portfolio, including the unconsolidated co-investment ventures in which we invest, has concentrations of properties in the same markets mentioned above, as well as in markets in France, Germany, Japan, Mexico and the United Kingdom, and are subject to the economic conditions in those markets.

A number of our investments, both wholly-owned and owned through co-investment ventures, are located in areas that are known to be subject to earthquake activity. U.S. properties located in active seismic areas include properties in the San Francisco Bay Area, Los Angeles, and Seattle. International properties located in active seismic areas include Japan and Mexico. We generally carry earthquake insurance on our properties located in areas historically subject to seismic activity, subject to coverage limitations and deductibles, if we believe it is commercially reasonable. We evaluate our earthquake insurance coverage annually in light of current industry practice through an analysis prepared by outside consultants and in some specific instances have elected to self-insure our earthquake exposure based on this analysis. We have elected not to carry earthquake insurance for our assets in Japan based on this analysis.

Furthermore, a number of our properties are located in areas that are known to be subject to hurricane or flood risk. We carry hurricane and flood hazard insurance on all of our properties located in areas historically subject to such activity, subject to coverage limitations and deductibles, if we believe it is commercially reasonable. We evaluate our insurance coverage annually in light of current industry practice through an analysis prepared by outside consultants.

Investments in real estate properties are subject to risks that could adversely affect our business.

Investments in real estate properties are subject to varying degrees of risk. While we seek to minimize these risks through geographic diversification of our portfolio, market research and our asset management capabilities, these risks cannot be eliminated. Factors that may affect real estate values include:

We may be unable to lease vacant space or renew leases or re-lease space on favorable terms as leases expire.

Our operating results and distributable cash flow would be adversely affected if a significant number of our customers were unable to meet their lease obligations. We are also subject to the risk that, upon the expiration of leases for space located in our properties, leases may not be renewed by existing customers, the space may not be

re-leased to new customers or the terms of renewal or re-leasing (including the cost of required renovations or concessions to customers) may be less favorable to us than current lease terms. Our competitors may offer space at rental rates below current market rates or below the rental rates we currently charge our customers, we may lose potential customers, and we may be pressured to reduce our rental rates below those we currently charge to retain customers when our customers’ leases expire. In the event of default by a significant number of customers, we may experience delays and incur substantial costs in enforcing our rights as landlord, and we may be unable to re-lease spaces. A customer may experience a downturn in its business, which may cause the loss of the customer or may weaken its financial condition, resulting in the customer’s failure to make rental payments when due or requiring a restructuring that might reduce cash flow from the lease. In addition, a customer may seek the protection of bankruptcy, insolvency or similar laws, which could result in the rejection and termination of such customer’s lease and thereby cause a reduction in our available cash flow.

We may acquire properties, which involves risks that could adversely affect our business and financial condition.  

We have acquired properties and will continue to acquire properties, both through the direct acquisition of real estate and through the acquisition of entities that own the real estate and through additional investments in co-investment ventures that acquire properties. The acquisition of properties involves risks, including the risk that the acquired property will not perform as anticipated and that any actual costs for rehabilitation, repositioning, renovation and improvements identified in the pre-acquisition due diligence process will exceed estimates. When we acquire properties, we may face risks associated with a lack of market knowledge or understanding of the local economy, forging new business relationships in the area and unfamiliarity with local government and permitting procedures. Additionally, there is, and it is expected there will continue to be, significant competition for properties that meet our investment criteria as well as risks associated with obtaining financing for acquisition activities. The acquired properties or entities may be subject to liabilities, which may be without any recourse, or with only limited recourse, with respect to unknown liabilities. As a result, if a liability were asserted against us based on ownership of any of these entities or properties, then we may have to pay substantial sums to settle it.

Our real estate development strategies may not be successful.

Our real estate development strategy is focused on monetizing land in the future through sales to third parties, development of industrial properties to hold for long-term investment or contribution or sale to a co-investment venture or third party, depending on market conditions, our liquidity needs and other factors. We may increase our investment in the development, renovation and redevelopment business and we expect to complete the build-out and leasing of our current development portfolio. We may also develop, renovate and redevelop properties within existing or newly formed co-investment ventures. The real estate development, renovation and redevelopment business includes the following significant risks:

We are subject to risks and liabilities in connection with forming co-investment ventures, investing in new or existing co-investment ventures, attracting third-party investment and investing in and managing properties through co-investment ventures.

At December 31, 2015, we had investments in real estate containing approximately 393 million square feet held through co-investment ventures, both public and private. Our organizational documents do not limit the amount of available funds that we may invest in these ventures, and we may and currently intend to develop and acquire properties through co-investment ventures and investments in other entities when warranted by the circumstances. However, there can be no assurance that we will be able to form new co-investment ventures, or attract third-party investment or that additional investments in new or existing ventures to develop or acquire properties will be successful. Further, there can be no assurance that we are able to realize value from such investments.

Our co-investment ventures involve certain additional risks that we do not otherwise face, including:

We generally seek to maintain sufficient influence over our co-investment ventures to permit us to achieve our business objectives; however, we may not be able to continue to do so indefinitely. We have formed publicly traded investment vehicles, such as NPR and FIBRA Prologis, for which we serve as sponsor or manager. We have contributed, and may continue to contribute, assets into such vehicles. There is a risk that our managerial relationship may be terminated. 

We are exposed to various environmental risks, including the potential impacts of future climate change, which may result in unanticipated losses that could affect our business and financial condition.

Under various federal, state and local laws, ordinances and regulations, a current or previous owner, developer or operator of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances. The costs of removal or remediation of such substances could be substantial. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release or presence of such hazardous substances. In addition, third parties may sue the owner or operator of a site for damages based on personal injury, property damage or other costs, including investigation and clean-up costs, resulting from the environmental contamination.

Environmental laws in some countries, including the U.S., also require that owners or operators of buildings containing asbestos properly manage and maintain the asbestos, adequately inform or train those who may come into contact with asbestos and undertake special precautions, including removal or other abatement, in the event that asbestos is disturbed during building renovation or demolition. These laws may impose fines and penalties on building owners or operators who fail to comply with these requirements and may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos. Some of our properties are known to contain asbestos-containing building materials.

In addition, some of our properties are leased or have been leased, in part, to owners and operators of businesses that use, store or otherwise handle petroleum products or other hazardous or toxic substances, creating a potential for the release of such hazardous or toxic substances. Furthermore, certain of our properties are on, adjacent to or near other properties that have contained or currently contain petroleum products or other hazardous or toxic substances, or upon which others have engaged, are engaged or may engage in activities that may release such hazardous or toxic substances. From time to time, we may acquire properties, or interests in properties, with known adverse environmental conditions for which we believe that the environmental liabilities associated with these conditions are quantifiable and that the acquisition will yield a superior risk-adjusted return. In connection with certain divested properties, we have agreed to remain responsible for, and to bear the cost of, remediating or monitoring certain environmental conditions on the properties.

We are also exposed to potential physical risks from possible future changes in climate. Our distribution facilities may be exposed to rare catastrophic weather events, such as severe storms or floods. If the frequency of extreme weather events increases due to climate change, our exposure to these events could increase. We do not currently consider ourselves to be exposed to regulatory risks related to climate change, as our operations generally do not emit a significant amount of greenhouse gases. However, we may be adversely impacted as a real estate developer in the future by potential impacts to the supply chain or stricter energy efficiency standards for buildings. We cannot give any assurance that other such conditions do not exist or may not arise in the future. The presence of such substances on our real estate properties could adversely affect our ability to lease, develop or sell such properties or to borrow using such properties as collateral, and this may have an adverse effect on our business and financial condition, and in particular, our distributable cash flow.

Our insurance coverage does not include all potential losses.

We and our unconsolidated co-investment ventures carry insurance coverage including property damage and rental loss insurance resulting from certain perils such as fire and additional perils as covered under an extended coverage policy, namely windstorm, flood, earthquake and terrorism; commercial general liability insurance; and environmental insurance, as appropriate for the markets where each of our properties and business operations are located. The insurance coverage contains policy specifications and insured limits customarily carried for similar properties, business activities and markets. We believe our properties and the properties of our unconsolidated co-investment ventures are adequately insured. Certain losses, however, including losses from floods, earthquakes, acts of war, acts of terrorism or riots, generally are not insured against or generally are not fully insured against because it is not deemed economically feasible or prudent to do so. If an uninsured loss or a loss in excess of insured limits occurs with respect to one or more of our properties, we could experience a significant loss of capital invested and future revenues in these properties and could potentially remain obligated under any recourse debt associated with the property.

Furthermore, we cannot be sure that the insurance companies will be able to continue to offer products with sufficient coverage at commercially reasonable rates. If we experience a loss that is uninsured or that exceeds insured limits with respect to one or more of our properties or if the insurance companies fail to meet their coverage commitments to us in the event of an insured loss, then we could lose the capital invested in the damaged properties, as well as the anticipated future revenue from those properties and, if there is recourse debt, then we would remain obligated for any mortgage debt or other financial obligations related to the properties. Any such losses or higher insurance costs could adversely affect our business.  

Risks Related to Financing and Capital

We may be unable to refinance our debt or our cash flow may be insufficient to make required debt payments.

We are subject to risks normally associated with debt financing, including the risk that our cash flow will be insufficient to meet required payments of principal and interest. There can be no assurance that we will be able to refinance any maturing indebtedness, that such refinancing would be on terms as favorable as the terms of the maturing indebtedness, or that we will be able to otherwise obtain funds by selling assets or raising equity to make required payments on maturing indebtedness. If we are unable to refinance our indebtedness at maturity or meet our payment obligations, our business and financial condition will be negatively impacted and, if the maturing debt is secured, the lender may foreclose on the property securing such indebtedness. Our credit facilities and certain other debt bears interest at variable rates. Increases in interest rates would increase our interest expense under these agreements.

Covenants in our credit agreements could limit our flexibility and breaches of these covenants could adversely affect our financial condition.

The terms of our various credit agreements, including our credit facilities, the indentures under which our senior notes are issued and other note agreements, require us to comply with a number of customary financial covenants, such as maintaining debt service coverage, leverage ratios, fixed charge ratios and other operating covenants including maintaining insurance coverage. These covenants may limit our flexibility to run our business, and breaches of these covenants could result in defaults under the instruments governing the applicable indebtedness. If we default under the covenant provisions and are unable to cure the default, refinance the indebtedness or meet payment obligations, our business and financial condition generally and, in particular, the amount of our distributable cash flow could be adversely affected.

Adverse changes in our credit ratings could negatively affect our financing activity.

The credit ratings of our senior unsecured notes and preferred stock are based on our operating performance, liquidity and leverage ratios, overall financial position and other factors employed by the credit rating agencies in their rating analyses of us. Our credit ratings can affect the amount of capital we can access, as well as the terms and pricing of any debt we may incur. There can be no assurance that we will be able to maintain our current credit ratings, and in the event our credit ratings are downgraded, we would likely incur higher borrowing costs and may encounter difficulty in obtaining additional financing. Also, a downgrade in our credit ratings may trigger additional payments or other negative consequences under our credit facilities and other debt instruments. Adverse changes in our credit ratings could negatively impact our business and, in particular, our refinancing and other capital market activities, our ability to manage debt maturities, our future growth and our development and acquisition activity.

At December 31, 2015, our credit ratings were Baa1 from Moody’s and BBB+ from S&P, both with outlook stable. A securities rating is not a recommendation to buy, sell or hold securities and is subject to revision or withdrawal at any time by the rating organization.

We depend on external sources of capital.

To qualify as a REIT, we are required each year to distribute to our stockholders at least 90% of our REIT taxable income (determined without regard to the dividends-paid deduction and by excluding any net capital gain) and we may be subject to tax to the extent our taxable income is not fully distributed. Historically, we have satisfied these distribution requirements by making cash distributions to our stockholders, but we may choose to satisfy these requirements by making distributions of cash or other property, including, in limited circumstances, our own stock. For distributions with respect to taxable years that ended on or before December 31, 2015, and in some cases declared as late as December 31, 2016, a REIT can satisfy up to 90% of the distribution requirements discussed above through the distribution of shares of our stock if certain conditions are met. Assuming we continue to satisfy these distribution requirements with cash, we may not be able to fund all future capital needs, including acquisition and development activities, from cash retained from operations and may have to rely on third-party sources of capital. Furthermore, to maintain our REIT status and not have to pay federal income and excise taxes, we may need to borrow funds on a short-term basis to meet the REIT distribution requirements even if the then-prevailing market conditions are not favorable for these borrowings. These short-term borrowing needs could result from differences in timing between the actual receipt of cash and inclusion of income for federal income tax purposes, or the effect of nondeductible capital expenditures, the creation of reserves or required debt or amortization payments. Our ability to access debt and equity capital on favorable terms or at all depends on a number of factors, including general market conditions, the market’s perception of our growth potential, our current and potential future earnings and cash distributions and the market price of our securities.

Our stockholders may experience dilution if we issue additional common stock or units in the Operating Partnership.

Any additional future issuance of common stock or operating partnership units will reduce the percentage of our common stock and units owned by investors. In most circumstances, stockholders and unitholders will not be entitled to vote on whether or not we issue additional common stock or units. In addition, depending on the terms and pricing of any additional offering of our common stock or units and the value of the properties, our stockholders and unitholders may experience dilution in both book value and fair value of their common stock or units.

Income Tax Risks

The failure of Prologis, Inc. to qualify as a REIT would have serious adverse consequences.

Prologis, Inc. elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code commencing with the taxable year ended December 31, 1997. We believe we have operated Prologis, Inc. to qualify as a REIT under the Internal Revenue Code and believe that the current organization and method of operation comply with the rules and regulations promulgated under the Internal Revenue Code to enable Prologis, Inc. to continue to qualify as a REIT. However, it is possible that we are organized or have operated in a manner that would not allow Prologis, Inc. to qualify as a REIT, or that our future operations could cause Prologis, Inc. to fail to qualify. Qualification as a REIT requires us to satisfy numerous requirements (some annually and others on a quarterly basis) established under highly technical and complex sections of the Internal Revenue Code for which there are only limited judicial and administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. For example, to qualify as a REIT, Prologis, Inc. must derive at least 95% of its gross income in any year from qualifying sources. In addition, Prologis, Inc. must pay dividends to its stockholders aggregating annually at least 90% of its taxable income (determined without regard to the dividends paid deduction and by excluding capital gains) and must satisfy specified asset tests on a quarterly basis. The provisions of the Internal Revenue Code and applicable Treasury regulations regarding qualification as a REIT are more complicated for Prologis, Inc. because we hold assets through the Operating Partnership.

If Prologis, Inc. fails to qualify as a REIT in any taxable year, we will be required to pay federal income tax (including any applicable alternative minimum tax) on taxable income at regular corporate rates. Unless we are entitled to relief under certain statutory provisions, Prologis, Inc. would be disqualified from treatment as a REIT for the four taxable years following the year in which it lost the qualification. If Prologis, Inc. lost its REIT status, our net earnings would be significantly reduced for each of the years involved.

Furthermore, we own a direct or indirect interest in certain subsidiary REITs that elected to be taxed as REITs under Sections 856 through 860 of the Internal Revenue Code. Provided that each subsidiary REIT qualifies as a REIT, our interest in such subsidiary REIT will be treated as a qualifying real estate asset for purposes of the REIT asset tests, and any dividend income or gains derived by us from such subsidiary REIT will generally be treated as income that qualifies for purposes of the REIT gross income tests. To qualify as a REIT, the subsidiary REIT must independently satisfy all of the REIT qualification requirements. If such subsidiary REIT were to fail to qualify as a REIT, and certain relief provisions did not apply, it would be treated as a regular taxable corporation and its income would be subject to U.S. federal income tax. In addition, a failure of the subsidiary REIT to qualify as a REIT would have an adverse effect on the ability of Prologis, Inc. to comply with the REIT income and asset tests, and thus its ability to qualify as a REIT.

Certain property transfers may generate prohibited transaction income, resulting in a penalty tax on gain attributable to the transaction.

From time to time, we may transfer or otherwise dispose of some of our properties, including by contributing properties to our co-investment ventures. Under the Internal Revenue Code, any gain resulting from transfers of properties we hold as inventory or primarily for sale to customers in the ordinary course of business is treated as income from a prohibited transaction subject to a 100% penalty tax. We do not believe that our transfers or disposals of property or our contributions of properties into our co-investment ventures are prohibited transactions. However, whether property is held for investment purposes is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. The Internal Revenue Service may contend that certain transfers or dispositions of properties by us or contributions of properties into our co-investment ventures are prohibited transactions. While we believe that the Internal Revenue Service would not prevail in any such dispute, if the Internal Revenue Code were to argue successfully that a transfer, disposition or contribution of property constituted a prohibited transaction, we would be required to pay a 100% penalty tax on any gain allocable to us from the prohibited transaction. In addition, income from a prohibited transaction might adversely affect our ability to satisfy the income tests for qualification as a REIT.

11

Legislative or regulatory action could adversely affect us.

In recent years, numerous legislative, judicial and administrative changes have been made to the U.S. and foreign income tax laws applicable to investments in real estate, REITs, similar entities and investments. Additional changes are likely to continue to occur in the future, both in and outside of the U.S. and may impact our taxation or that of our stockholders.

Geographic Distribution

We are invested in real estate properties that are predominately industrial properties. Our properties are typically used for distribution, storage, packaging, assembly and light manufacturing of consumer and industrial products. The vast majority of our operating properties are used by our customers for bulk distribution.

We manage our business on an owned and managed basis whether a property is wholly owned by us or owned by one of our co-investment ventures. We believe that the operating fundamentals of our owned and managed portfolio are consistent with those of our consolidated portfolio and therefore allow us to make business decisions based on the property operations versus our ownership. As such, we have included operating property information for Real Estate Operations and our owned and managed portfolio. The owned and managed portfolio includes the properties we consolidate and the properties owned by our unconsolidated co-investment ventures reflected at 100% of the ventures, not our proportionate share.

Included in Real Estate Operations are 628 buildings owned primarily by two co-investment ventures that we consolidate but of which we own less than 100% of the equity. No individual property or group of properties operating as a single business unit amounted to 10% or more of our consolidated total assets at December 31, 2015, or generated income equal to 10% or more of our consolidated gross revenues for the year ended December 31, 2015.
