The Mergers

The Merger Agreement (See page 99)

        The Prologis parties and the DCT parties have entered into the merger agreement attached as Annex A to this proxy statement/prospectus, which is incorporated herein by reference. Prologis and DCT encourage you to carefully read the merger agreement in its entirety because it is the principal document governing the mergers and the other transactions contemplated by the merger agreement.

        The merger agreement provides that the closing of the mergers will take place at the offices of Goodwin Procter LLP, Three Embarcadero Center, San Francisco, California 94111 on the second business day following the date on which the last of the conditions to closing of the mergers has been satisfied or waived.

The Mergers (See page 54)

        Upon the terms and subject to the conditions set forth in the merger agreement:

•

DCT will merge with and into Prologis, so that Prologis will be the surviving entity in the merger; and



•

DCT OP will merge with and into Prologis OP, so that Prologis OP will be the surviving entity in the merger.

        Upon the consummation of the mergers described above, the separate existences of DCT and DCT OP will cease.

The Merger Consideration (See page 100)

        In the company merger, each share of DCT common stock issued and outstanding immediately prior to the company merger effective time will be automatically converted into the right to receive 1.02 validly issued, fully paid and non-assessable shares of Prologis common stock, subject to any withholding required under applicable tax law, plus the right, if any, to receive cash in lieu of fractional shares of Prologis common stock into which such shares of DCT common stock would have been converted pursuant to the merger agreement.

        In the partnership merger, each DCT OP common unit outstanding immediately prior to the partnership merger effective time will be automatically converted into the right to receive 1.02 validly issued common units of Prologis OP. No fractional common units of Prologis OP will be issued in the partnership merger. Any fractional common unit of Prologis OP that would otherwise be issued to any holder of DCT OP common units will be rounded up to the nearest whole number.

Recommendation of the DCT Board of Directors (See page 48)

        The DCT Board has unanimously (i) determined and declared that the mergers are advisable and in the best interests of DCT and its stockholders; (ii) approved each of the mergers and the other transactions contemplated by the merger agreement; and (iii) approved the merger agreement. The DCT Board made its determination after consultation with its legal and financial advisors and consideration of numerous factors.

        The DCT Board unanimously recommends that the DCT stockholders vote FOR the proposal to approve the company merger on the terms and conditions set forth in the merger agreement, FOR the non-binding advisory proposal to approve certain compensation that may be paid or become payable to certain named executive officers of DCT in connection with the mergers and the transactions contemplated under the merger agreement, and FOR the proposal to approve one or more adjournments of the DCT special meeting to another date, time or place, if necessary, to solicit additional proxies in favor of the proposal to approve the company merger on the terms and conditions set forth in the merger agreement.

The DCT Special Meeting (See page 48)

        DCT has agreed to hold a special meeting for the purpose of voting upon the approval of the company merger and other related matters. The DCT Board has agreed to recommend that the DCT stockholders approve the company merger and to use its reasonable best efforts to solicit the approval of the company merger at the special meeting. The special meeting of the DCT stockholders will be held at 555 17th Street, Suite 3700, Denver, Colorado 80202 on August 20, 2018, commencing at 10:00 a.m., local time.

        At the DCT special meeting, the DCT stockholders will be asked to consider and vote upon the following matters:

1.

a proposal to approve the company merger on the terms and conditions set forth in the merger agreement;



2.

a non-binding advisory proposal to approve certain compensation that may be paid or become payable to certain named executive officers of DCT in connection with the mergers and the transactions contemplated under the merger agreement; and



3.

a proposal to approve one or more adjournments of the DCT special meeting to another date, time or place, if necessary, to solicit additional proxies in favor of the proposal to approve the company merger on the terms and conditions set forth in the merger agreement.

        Approval of the proposal to approve the company merger on the terms and conditions set forth in the merger agreement requires the affirmative vote of holders of a majority of the shares of outstanding DCT common stock entitled to vote on such proposal.

        Approval of the non-binding advisory proposal to approve certain compensation that may be paid or become payable to certain named executive officers of DCT in connection with the mergers and the transactions contemplated under the merger agreement requires the affirmative vote of a majority of all votes cast on such proposal.

        Approval of the proposal to approve one or more adjournments of the DCT special meeting to another date, time or place, if necessary, to solicit additional proxies in favor of the proposal to approve the company merger on the terms and conditions set forth in the merger agreement requires the affirmative vote of a majority of all votes cast on such proposal. Regardless of the outcome of the foregoing proposal, in accordance with DCT's bylaws and Maryland law, the chairman of the DCT special meeting will retain full authority to conclude, recess or adjourn the DCT special meeting to a later date and time and at a place announced at the DCT special meeting for any purpose, including, without limitation, to solicit additional proxies in favor of the proposal to approve the company merger on the terms and conditions set forth in the merger agreement, or to postpone the DCT special meeting before it is convened, without a vote of the DCT stockholders.

        At the close of business on the record date, directors and executive officers of DCT were entitled to vote 163,380 shares of DCT common stock, or approximately 0.17% of the shares of DCT common stock issued and outstanding on that date. DCT currently expects that all DCT directors and executive officers will vote their shares of DCT common stock in favor of the proposal to approve the company merger on the terms and conditions set forth in the merger agreement as well as the other proposals to be considered at the DCT special meeting, although none of them is contractually obligated to do so.

        Your vote as a DCT stockholder is very important. Accordingly, please sign and return the enclosed proxy card whether or not you plan to attend the DCT special meeting in person.

Opinion of DCT's Financial Advisor (See page 67 and Annex B)

        In connection with the company merger, Merrill Lynch, Pierce, Fenner & Smith Incorporated, or BofA Merrill Lynch, DCT's financial advisor, delivered to the DCT Board a written opinion, dated April 29, 2018, as to the fairness, from a financial point of view and as of the date of the opinion, to the holders of DCT common stock of the Exchange Ratio provided for in the company merger. The full text of the written opinion, dated April 29, 2018, of BofA Merrill Lynch, which describes, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken, is attached as Annex B to this document and is incorporated by reference herein in its entirety. BofA Merrill Lynch provided its opinion to the DCT Board (in its capacity as such) for the benefit and use of the DCT Board in connection with and for purposes of its evaluation of the merger consideration from a financial point of view. BofA Merrill Lynch's opinion does not address any other aspect of the company merger and no opinion or view was expressed as to the relative merits of the company merger in comparison to other strategies or transactions that might be available to DCT or in which DCT might engage or as to the underlying business decision of DCT to proceed with or effect the company merger. BofA Merrill Lynch's opinion does not constitute a recommendation to any stockholder as to how to vote or act in connection with the company merger or any other matter.

Treatment of the DCT Equity Awards (See pages 83 and 102)

        Long-Term Incentive Plan Units.    Immediately prior to the partnership merger effective time, each issued and outstanding (i) unvested DCT LTIP unit shall automatically become fully vested in accordance with the terms of the DCT equity incentive plan and award agreement or other agreement or document evidencing such DCT LTIP unit, and (ii) vested DCT LTIP unit eligible for conversion

into a DCT OP common unit prior to or at the partnership merger effective time shall automatically be converted into a DCT OP common unit pursuant to the DCT OP partnership agreement. At the partnership merger effective time, each issued and outstanding DCT LTIP unit not previously converted into a DCT OP common unit, if any, shall be automatically converted into 1.02 Prologis LTIP units. No fractional Prologis LTIP units will be issued in connection with the conversion of such DCT LTIP units. Any fractional Prologis LTIP units that would otherwise be issued to any holder of DCT LTIP units shall be rounded up to the nearest whole number and the holder of DCT LTIP units shall not be entitled to any further consideration with respect thereto.

        Restricted Stock.    Immediately prior to the company merger effective time, each issued and outstanding unvested share of DCT common stock subject to a DCT restricted stock award granted under the DCT equity incentive plan shall automatically become fully vested, contingent upon the closing of the company merger, and shall automatically be converted into the right to receive the merger consideration in the same manner as all other shares of DCT common stock.

        Stock Options.    At the company merger effective time, each outstanding and unexercised option to purchase DCT common stock granted under the DCT equity incentive plan will vest in full and will terminate and will be converted into the right of the holder thereof to receive a number of shares of Prologis common stock, rounded down to the nearest whole number of shares, equal to (a) the Exchange Ratio multiplied by (b) the number of shares of DCT common stock obtained by (i) multiplying (A) the number of shares of DCT common stock that were subject to such option immediately prior to the company merger effective time by (B) the excess, if any, of the fair market value of a share of DCT common stock determined immediately prior to the company merger effective time over the per share exercise price of such option, and (ii) dividing the resulting amount determined under (i) by the fair market value of a share of DCT common stock determined immediately prior to the company merger effective time.

        Phantom Shares.    At the company merger effective time, each outstanding DCT phantom share granted under the DCT equity incentive plan will vest in full and the holder thereof will receive a number of shares of Prologis common stock per DCT phantom share equal to the number of shares of Prologis common stock that each DCT stockholder is entitled to receive per share of DCT common stock as the merger consideration.

        See "The Merger Agreement—Merger Consideration; Effects of the Company Merger and the Partnership Merger—DCT Equity Incentive Plans" on page 102 for more information.

Directors and Management of the Combined Company After the Mergers (See page 129)

        Immediately following the effective time of the company merger, the board of directors of the Combined Company will be increased to 12 members, with the 11 current Prologis directors, Hamid R. Moghadam, Irving F. Lyons III, Cristina G. Bita, George L. Fotiades, Lydia H. Kennard, J. Michael Losh, David P. O'Connor, Olivier Piani, Jeffrey L. Skelton, Carl B. Webb and William D. Zollars, continuing as directors of the Combined Company. In addition, Philip L. Hawkins will join the board of directors of the Combined Company, to serve until the next annual meeting of the stockholders of the Combined Company (and until his successor qualifies and is duly elected). In the merger agreement, Prologis also agreed to nominate Mr. Hawkins for reelection at the 2019 annual meeting of Prologis' stockholders to serve until the next subsequent annual meeting of Prologis' stockholders and until his successor is duly elected and qualifies. Mr. Hawkins is currently DCT's President and Chief Executive Officer and a member of the DCT Board.

        The executive officers of Prologis immediately prior to the effective time of the company merger will continue to serve as the executive officers of the Combined Company, with Hamid R. Moghadam continuing to serve as the Chief Executive Officer of the Combined Company. See "The Merger

Agreement—Board of Directors of Prologis Following the Mergers" on page 100 and "Directors and Management of the Combined Company After the Mergers" on page 129 for more information.

Interests of DCT's Directors and Executive Officers in the Mergers (See page 82)

        The interests of DCT's directors and executive officers in the mergers that are different from, or in addition to, those of DCT's stockholders generally are described below. The DCT Board was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the mergers, and in recommending that the DCT stockholders approve the company merger and the other transactions contemplated by the merger agreement. These interests include:

•

accelerated vesting of all outstanding equity awards and settlement of all outstanding DCT phantom shares;



•

payment of pro rata annual cash bonuses for 2018;



•

entitlement to severance benefits under a preexisting employment agreement with DCT's Chief Executive Officer and DCT's Executive Change in Control and Severance Plan covering DCT's other executive officers; and



•

entitlement to continued indemnification, expense advancement and insurance coverage under indemnification agreements and the merger agreement.

Listing of Prologis Common Stock; Delisting and Deregistration of DCT Common Stock (See page 98)

        It is a condition to each party's obligation to complete the mergers that the shares of Prologis common stock to be issued in connection with the mergers be approved for listing on the NYSE, subject to official notice of issuance. Prologis has agreed to use its reasonable best efforts to have the application for the listing of the Prologis common stock accepted by the NYSE as promptly as is practicable. After the company merger is completed, the shares of DCT common stock currently listed on the NYSE will cease to be listed on the NYSE and will be deregistered under the Exchange Act.

Stockholder Appraisal Rights in the Mergers (See page 103)

        No dissenters' or appraisal rights or rights of objecting stockholders will be available with respect to the mergers or the other transactions contemplated by the merger agreement.

Conditions to Completion of the Mergers (See page 122)

        The respective obligations of each of the DCT, DCT OP, Prologis and Prologis OP to effect the mergers are subject to the satisfaction or waiver of certain customary conditions, including the approval of the company merger by the DCT stockholders, the absence of any legal prohibitions, the accuracy of the representations and warranties, subject to customary materiality qualifiers, and compliance by the other parties with their respective obligations under the merger agreement, subject to customary materiality qualifiers.

        Neither DCT nor Prologis can be certain when, or if, the conditions to the mergers will be satisfied or waived, or that the mergers will be effected. See "The Merger Agreement—Conditions to Completion of the Mergers" beginning on page 122 for more information.

Regulatory Approvals Required for the Mergers (See page 91)

        The consummation of the mergers and the other transactions contemplated by the merger agreement is not subject to the receipt of any governmental approvals or the expiration of any regulatory waiting period.

Non-Solicitation of Acquisition Proposals (See page 115)

        The merger agreement provides that DCT shall not, and shall cause its subsidiaries and its and their respective officers and directors not to, and shall instruct and use its reasonable best efforts to cause its and their respective affiliates, trustees, employees or consultants or investment bankers, financial advisors, attorneys, accountants or other representative retained by such person or entity not to, directly or indirectly:

•

solicit, initiate or knowingly encourage or knowingly facilitate (including by way of furnishing non-public information), any inquiries, indications of interest or the making of any proposal or offer that constitutes, or would reasonably be expected to lead to, an acquisition proposal (as defined in "The Merger Agreement—No Solicitation of Transactions");



•

engage in, continue or otherwise participate in any negotiations or discussions concerning, or provide any non-public information or data to any person or entity relating to, an acquisition proposal or any inquiries, proposals, indications of interest or offers that constitute, or would reasonably be expected to lead to an acquisition proposal;



•

approve or execute or enter into any letter of intent, agreement in principle, merger agreement, asset purchase or share exchange agreement, option agreement or other similar agreement providing for any acquisition proposal; or



•

propose or agree to do any of the foregoing.

        DCT or its representatives may, however, contact a person or entity who has submitted an unsolicited bona fide written acquisition proposal for the sole purpose of clarifying the terms of such acquisition proposal in connection with determining whether such acquisition proposal constitutes, or would reasonably be likely to lead to, a superior proposal.

        Notwithstanding these restrictions, under certain circumstances, and to the extent that the DCT Board concludes in good faith, after receiving the advice of its outside legal counsel and its financial advisors, that an acquisition proposal either constitutes or would reasonably be expected to lead to a superior proposal (as defined in "The Merger Agreement—No Solicitation of Transactions") and that failure to do so would be inconsistent with their duties as directors under applicable law, DCT may, prior to the time the company merger is approved by the DCT stockholders, make available non-public information or data, and engage in discussions and negotiations, with respect to certain unsolicited bona fide written acquisition proposals that did not result from a breach of the merger agreement.

        See "The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions" on page 115 for more information.

No Change of Board Recommendation; No Entry into Alternative Transactions (See page 115)

        Prior to obtaining the approval of the DCT stockholders of the company merger, the DCT Board may make a change in company recommendation (as defined in "The Merger Agreement—No Solicitation of Transactions" beginning on page 115), if and only if:

•

(i) DCT has received an unsolicited bona fide written acquisition proposal that did not result from a breach of DCT's non-solicitation covenant and covenants restricting the sharing of information in the merger agreement (and such proposal is not withdrawn) and the DCT Board concludes in good faith (after consultation with its outside legal counsel and its financial advisors) that such acquisition proposal constitutes a superior proposal or (ii) an intervening event (as defined in "The Merger Agreement—No Solicitation of Transactions") has occurred, and in the case of either (i) or (ii), the DCT Board concludes in good faith (after consultation with its outside counsel) that the failure to take such action would be inconsistent with their duties as directors under applicable law;

•

DCT gives Prologis at least four business days' prior written notice of its intention to take such action and which notice (i) in the case of an acquisition proposal, specifies in reasonable detail the reasons for DCT taking such action, including the material terms and conditions of any such superior proposal that is the basis of the proposed action and (ii) in the case of an intervening event, advising Prologis that DCT intends to take such action and specifying in reasonable detail the reasons therefor; and



•

during such notice period, the DCT Board considers, and, if requested by Prologis, engages and causes its representatives to engage in good faith discussions with Prologis regarding any adjustment or modification of the terms of the merger agreement proposed by Prologis and the DCT Board, following such notice period, again concludes in good faith (after consultation with its outside legal counsel and its financial advisors and taking into account any adjustment or modification of the terms of the merger agreement proposed by Prologis) that (i) in the case of both an acquisition proposal and an intervening event, the failure to do so would be inconsistent with their duties as directors under applicable law and (ii) in the case of an acquisition proposal, such acquisition proposal continues to constitute a superior proposal.

        Unless the merger agreement is terminated with respect to a superior proposal, notwithstanding a change in company recommendation, DCT shall cause the approval of the company merger to be submitted to a vote of its stockholders. In addition, DCT shall not submit to the vote of its stockholders any acquisition proposal other than the company merger prior to the termination of the merger agreement.

        See "The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions" on page 115 for more information.

Termination of the Merger Agreement (See page 125)

        The merger agreement may be terminated and the mergers may be abandoned at any time prior to the partnership merger effective time, whether before or after the receipt of the approval of the company merger by the DCT stockholders, under the following circumstances:

•

by mutual written consent of DCT and Prologis;



•

by either DCT or Prologis if:



•

upon a vote at the DCT stockholder meeting, the approval of the company merger by the DCT stockholders is not obtained (except this right to terminate is not available to DCT if the failure to obtain such DCT stockholder approval was primarily caused by any action or failure to act of any of the DCT parties that constitutes a material breach of their respective obligations with respect to the preparation of the proxy statement/prospectus or holding the DCT stockholder meeting or non-solicitation of acquisition proposals and changes in the recommendation of the DCT Board);



•

a governmental authority of competent jurisdiction shall have issued an order, decree, judgment, injunction or taken any other action, which permanently restrains, enjoins or otherwise prohibits or makes illegal the consummation of the mergers, and such order, decree, judgment, injunction or other action shall have become final and non-appealable; or



•

the mergers shall not have been consummated on or before 5:00 p.m. (New York time) on December 31, 2018, or the Outside Closing Date, unless the failure to consummate the mergers on or before such date shall have been primarily caused by, or the result of, the failure of the party seeking to terminate the merger agreement to comply with any provision of the merger agreement.

•

by DCT if:



•

at any time prior to the receipt of the approval of the company merger by the DCT stockholders, in order to enter into an acquisition agreement with respect to a superior proposal in compliance with the terms of the merger agreement (provided that the merger agreement may not be so terminated unless DCT concurrently pays the termination fee described below); or



•

there has been a breach or failure to perform in any material respect by any of the Prologis parties of any of the covenants or agreements or any of the representations or warranties set forth in the merger agreement on the part of any of the Prologis parties, which breach or failure to perform, either individually or in the aggregate, would result in, if occurring or continuing on the closing date, the failure to be satisfied of certain closing conditions, unless such breach is reasonably capable of being cured by the earlier of 30 days after notice of such breach or failure to perform is given or two business days prior to the Outside Closing Date unless any of the DCT parties is in breach of any of its own respective representations, warranties, covenants or agreements set forth in the merger agreement such that certain closing conditions would not be satisfied.



•

by Prologis if:



•

prior to obtaining the approval of the DCT stockholders of the company merger, the DCT Board shall make a change in company recommendation;



•

upon a willful breach of the non-solicitation covenants by any DCT party; or



•

there has been a breach or failure to perform in any material respect by any of the DCT parties of any of the covenants or agreements or any of the representations or warranties set forth in the merger agreement on the part of any of the DCT parties, which breach or failure to perform, either individually or in the aggregate, would result in, if occurring or continuing on the closing date, the failure to be satisfied of certain closing conditions, unless such breach is reasonably capable of being cured by the earlier of 30 days after notice of such breach or failure to perform is given or two business days prior to the Outside Closing Date unless any of the Prologis parties is in breach of any of its own respective representations, warranties, covenants or agreements set forth in the merger agreement such that certain closing conditions would not be satisfied.

        See "The Merger Agreement—Termination of the Merger Agreement" beginning on page 125 for more information.

Termination Fee and Expenses (See page 126)

        DCT must pay to Prologis a termination fee in the amount of $216 million if the merger agreement is terminated in the following circumstances:

•

DCT terminates the merger agreement, at any time prior to the receipt of the DCT stockholder approval, to enter into an acquisition agreement with respect to a superior proposal; or



•

Prologis terminates the merger agreement following a change in company recommendation by the DCT Board.

        DCT must pay to Prologis a termination fee in the amount of $216 million in the following instances (provided that for purposes of the analysis below, the references to "20%" in the definition of "acquisition proposal" in the merger agreement shall instead be "50%"):

•

In the event that:



•

DCT receives or has received a bona fide acquisition proposal with respect to DCT that has been publicly announced or otherwise communicated to the DCT Board prior to the time of the DCT stockholder meeting;



•

thereafter (i) DCT or Prologis terminates the merger agreement as a result of the failure to obtain the approval of the company merger by the DCT stockholders following a vote at the DCT stockholder meeting, (ii) DCT or Prologis terminates the merger agreement for the failure of the consummation of the mergers to occur on or before the Outside Closing Date or (iii) Prologis terminates the merger agreement as a result of DCT's or DCT OP's breach or failure to perform in any material respect any of its representations, warranties, covenants or agreements contained in the merger agreement, subject to a cure right as further described below; and



•

before the date that is twelve months after the date of termination of the merger agreement, DCT consummates an acquisition proposal or enters into an acquisition agreement.

        However, the termination fee will only be $100 million if:

•

the merger agreement is terminated:



•

by DCT prior to the receipt of the DCT stockholder approval in order to enter into an acquisition agreement with respect to a superior proposal from a qualified bidder in compliance with the merger agreement; or



•

by Prologis following a change in company recommendation by the DCT Board as a result of superior proposal from a qualified bidder; and



•

a bidder will be a qualified bidder if such bidder made a bona fide written acquisition proposal on or prior to 11:59 p.m. (New York time) on May 29, 2018 that, on or prior to such date, the DCT Board concluded in good faith (after consultation with its outside legal counsel and its financial advisors) either constituted or would reasonably be expected to lead to a superior proposal; and



•

the termination of the merger agreement occurred prior to the later of the following:



•

11:59 p.m. (New York time) on June 13, 2018; and



•

11:59 p.m. (New York time) on the first day after the end of any notice period (including any extensions thereof) with respect to a superior proposal by a qualified bidder for which such notice period commenced on or prior to June 13, 2018.

        DCT did not receive a bona fide written acquisition proposal from any bidders, including any qualified bidders, on or prior to 11:59 p.m. (New York time) on May 29, 2018.

        DCT has agreed to pay to Prologis all documented reasonable out-of-pocket expenses (including fees and expenses of counsel and other advisors) paid or payable by any of the Prologis parties in connection with the merger agreement and the transactions contemplated by the merger agreement up to a maximum of $15 million if the merger agreement is terminated by either DCT or Prologis because the DCT stockholders fail to approve the company merger at a duly convened meeting. See "The Merger Agreement—Termination of the Merger Agreement" beginning on page 125 for more information.

Table of Contents

Remedies (See page 128)

        The parties to the merger agreement are entitled to seek an injunction or injunctions to prevent breaches of the merger agreement by any other party and to specifically enforce the terms and provisions of the merger agreement.

Litigation Relating to the Mergers (See page 98)

        On July 2, 2018, DCT, DCT OP, the DCT Board, Prologis, and Prologis OP were sued in a putative class action lawsuit, captioned Rosenblatt v. DCT Industrial Trust Inc. et al., Case No. 1:18-cv-01678 (the "Rosenblatt Action"), filed in the United States District Court for the District of Colorado, in connection with DCT's proposed merger with Prologis and the related Form S-4. The complaint in the Rosenblatt Action alleges that DCT, DCT OP, the DCT Board, Prologis, and Prologis OP violated federal securities laws by omitting material information from the Form S-4, rendering the Form S-4 materially deficient. On July 10, 2018, DCT and the DCT Board were sued in another putative class action lawsuit, captioned Bushansky v. DCT Industrial Trust, Inc., Case No. 1:18-cv-01758 (the "Bushansky Action"), also filed in the United States District Court for the District of Colorado, and also in connection with DCT's proposed merger with Prologis and the related Form S-4. The complaint in the Bushansky Action alleges that DCT and the DCT Board violated federal securities laws by omitting from the Form S-4, and/or misrepresenting in the Form S-4, material information, rendering the Form S-4 materially deficient. Plaintiffs in the Rosenblatt and Bushansky Actions seek, among other things, (i) to enjoin the transaction (or rescind it to the extent it is completed), and (ii) attorneys' fees and costs in connection with these lawsuits. If additional similar complaints are filed, absent new or different allegations that are material, neither DCT nor Prologis will necessarily announce such additional filings.

        Although the ultimate outcome of litigation cannot be predicted with certainty, DCT and Prologis believe that these lawsuits are without merit and intend to defend against these actions vigorously.

        Prologis and DCT intend that the company merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. The closing of the mergers is conditioned on the receipt by each of Prologis and DCT of an opinion from its respective counsel to the effect that the company merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Assuming that the company merger qualifies as a reorganization, United States holders of shares of DCT common stock are not expected to recognize gain or loss as a result of the company merger (except with respect to the receipt of cash in lieu of fractional shares of Prologis common stock).

        For further discussion of certain United States federal income tax consequences of the company merger and the ownership and disposition of the Combined Company common stock, see "The Mergers—Material United States Federal Income Tax Consequences of the Company Merger" beginning on page 92 and "Material United States Federal Income Tax Considerations Applicable to Holders of the Combined Company Stock" beginning on page 130.

        Holders of shares of DCT common stock should consult their tax advisors to determine the tax consequences to them (including the application and effect of any state, local or non-United States income and other tax laws) of the company merger and the ownership and disposition of the Combined Company common stock.

Accounting Treatment of the Mergers (See page 97)

        Prologis prepares its financial statements in accordance with United States generally accepted accounting principles, which we refer to as GAAP. The mergers will be accounted for by using the

business combination accounting rules. See "The Merger—Accounting Treatment" beginning on page 97 for more information.

Comparison of Rights of Prologis Stockholders and DCT Stockholders (See page 163)

        The rights of DCT stockholders are currently governed by and subject to the provisions of the Maryland General Corporation Law, or the MGCL, and the charter and bylaws of DCT. Upon consummation of the company merger, the rights of the former DCT stockholders who receive shares of Prologis common stock in the company merger will be governed by the MGCL and the Prologis charter and bylaws, rather than the charter and bylaws of DCT. In particular, as is typical for REITs in order to protect their status as a REIT, the Prologis charter provides that, with limited exceptions, no person may beneficially own, or be deemed to beneficially own by virtue of the attribution provisions of the Code, more than 9.8% of the outstanding shares of Prologis' capital stock.

Funds From Operations Attributable to Common Stockholders/Unitholders

        Funds From Operations, or FFO, is a non-GAAP financial measure that is commonly used in the real estate industry. The most directly comparable GAAP measure to FFO is net earnings.

        The National Association of Real Estate Investment Trusts, or NAREIT, defines FFO as earnings computed under GAAP to exclude historical cost depreciation and gains and losses from the sales, along with impairment charges, of depreciable properties. Prologis also excludes the gains on revaluation of equity investments upon acquisition of a controlling interest and the gain recognized from a partial sale of its investment, as these are similar to gains from the sales of depreciable properties. Prologis excludes similar adjustments from its unconsolidated entities and the third parties' share of its consolidated co-investment ventures.

        Prologis' FFO Measures.    Prologis' FFO measures begin with NAREIT's definition, and Prologis makes certain adjustments to reflect its business and the way that management plans and executes its business strategy. While not infrequent or unusual, the additional items Prologis adjusts for in calculating FFO, as modified by Prologis and Core FFO (both as defined below), are subject to significant fluctuations from period to period. Although these items may have a material impact on Prologis' operations and are reflected in its financial statements, the removal of the effects of these items allows Prologis to better understand the core operating performance of its properties over the long-term. These items have both positive and negative short-term effects on Prologis' results of operations in inconsistent and unpredictable directions that are not relevant to its long-term outlook.

        Prologis calculates its FFO measures, as defined below, based on its proportionate ownership share of both its unconsolidated and consolidated ventures. Prologis reflects its share of its FFO measures for unconsolidated ventures by applying its average ownership percentage for the period to the applicable reconciling items on an entity by entity basis. Prologis reflects its share for consolidated ventures in which it does not own 100% of the equity by adjusting its FFO measures to remove the noncontrolling interests share of the applicable reconciling items based on its average ownership percentage for the applicable periods.

        These FFO measures are used by Prologis' management as supplemental financial measures of operating performance and it believes that it is important that stockholders, potential investors and financial analysts understand the measures management uses. Prologis does not use its FFO measures as, nor should they be considered to be, alternatives to net earnings computed under GAAP, as indicators of Prologis' operating performance, as alternatives to cash from operating activities computed under GAAP or as indicators of Prologis' ability to fund its cash needs.

        Prologis analyzes its operating performance primarily by the rental revenues of its real estate and the revenues from its strategic capital business, net of operating, administrative and financing expenses. This income stream is not directly impacted by fluctuations in the market value of our investments in real estate or debt securities.

        FFO, as modified by Prologis attributable to common stockholders and unitholders, or FFO, as modified by Prologis.    To arrive at FFO, as modified by Prologis, Prologis adjusts the NAREIT defined FFO measure to exclude the impact of foreign currency related items and deferred tax, specifically:

•

deferred income tax benefits and deferred income tax expenses recognized by its subsidiaries;



•

current income tax expense related to acquired tax liabilities that were recorded as deferred tax liabilities in an acquisition, to the extent the expense is offset with a deferred income tax benefit in earnings that is excluded from its defined FFO measure;



•

unhedged foreign currency exchange gains and losses resulting from debt transactions between Prologis and its foreign consolidated subsidiaries and its foreign unconsolidated entities;



•

foreign currency exchange gains and losses from the remeasurement (based on current foreign currency exchange rates) of certain third-party debt of Prologis' foreign consolidated and unconsolidated entities; and



•

mark-to-market adjustments associated with derivative financial instruments.

        Prologis uses FFO, as modified by Prologis, so that management, analysts and investors are able to evaluate Prologis' performance against other REITs that do not have similar operations or operations in jurisdictions outside the United States.

        Core FFO attributable to common stockholders and unitholders, or Core FFO.    In addition to FFO, as modified by Prologis, Prologis also uses Core FFO. To arrive at Core FFO, Prologis adjusts FFO, as modified by Prologis, to exclude the following recurring and nonrecurring items that Prologis recognized directly in FFO, as modified by Prologis:

•

gains or losses from the disposition of land and development properties that were developed with the intent to contribute or sell;



•

income tax expense related to the sale of investments in real estate and third-party acquisition costs related to the acquisition of real estate;



•

impairment charges recognized related to Prologis' investments in real estate generally as a result of its change in intent to contribute or sell these properties;



•

gains or losses from the early extinguishment of debt and redemption and repurchase of preferred stock; and



•

expenses related to natural disasters.

        Prologis uses Core FFO, including by segment and region, to: (i) assess its operating performance as compared to other real estate companies; (ii) evaluate its performance and the performance of its properties in comparison with expected results and results of previous periods; (iii) evaluate the performance of its management; (iv) budget and forecast future results to assist in the allocation of resources; (v) provide guidance to the financial markets to understand its expected operating performance; and (vi) evaluate how a specific potential investment will impact its future results.

        Limitations on the use of Prologis' FFO measures.    While Prologis believes its modified FFO measures are important supplemental measures, neither NAREIT's nor Prologis' measures of FFO should be used alone because they exclude significant economic components of net earnings computed

under GAAP and are, therefore, limited as an analytical tool. Accordingly, these are only a few of the many measures Prologis uses when analyzing its business. Some of the limitations are:

•

The current income tax expenses and acquisition costs that are excluded from Prologis' modified FFO measures represent the taxes and transaction costs that are payable.



•

Depreciation and amortization of real estate assets are economic costs that are excluded from FFO. FFO is limited, as it does not reflect the cash requirements that may be necessary for future replacements of the real estate assets. Furthermore, the amortization of capital expenditures and leasing costs necessary to maintain the operating performance of logistics facilities are not reflected in FFO.



•

Gains or losses from non-development property dispositions and impairment charges related to expected dispositions represent changes in value of the properties. By excluding these gains and losses, FFO does not capture realized changes in the value of disposed properties arising from changes in market conditions.



•

The deferred income tax benefits and expenses that are excluded from Prologis' modified FFO measures result from the creation of a deferred income tax asset or liability that may have to be settled at some future point. Prologis' modified FFO measures do not currently reflect any income or expense that may result from such settlement.



•

The foreign currency exchange gains and losses that are excluded from Prologis' modified FFO measures are generally recognized based on movements in foreign currency exchange rates through a specific point in time. The ultimate settlement of Prologis' foreign currency-denominated net assets is indefinite as to timing and amount. Prologis' FFO measures are limited in that they do not reflect the current period changes in these net assets that result from periodic foreign currency exchange rate movements.



•

The gains and losses on extinguishment of debt or preferred stock that Prologis excludes from its Core FFO, may provide a benefit or cost to Prologis as it may be settling its debt at less or more than its future obligation.



•

The natural disaster expenses that Prologis excludes from Core FFO are costs that Prologis has incurred.

        Prologis compensates for these limitations by using its FFO measures only in conjunction with net earnings computed under GAAP when making its decisions. This information should be read with Prologis' complete consolidated financial statements prepared under GAAP. To assist investors in compensating for these limitations, Prologis reconciles its modified FFO measures to its net earnings computed under GAAP below.

        The following table is a reconciliation of Prologis' FFO measures to net earnings computed under GAAP for the three months ended March 31, 2018 and 2017 and for each of the years during the five-year period ended December 31, 2017:
