 Exhibit 4.2 

Officers’ Certificate 

June 7, 2017 
 The
undersigned officers of Prologis, Inc. (“Prologis, Inc.”), general partner of Prologis, L.P. (the “Company”), on behalf of the Company, acting pursuant to resolutions adopted by the Board of Directors of Prologis,
Inc. (the “Board”) on May 3, 2017 and the Securities Offering Transaction Committee of the Board on May 31, 2017, hereby establish a series of debt securities by means of this Officers’ Certificate in accordance with
the Indenture, dated as of June 8, 2011 (the “Base Indenture,” and as supplemented by the First Supplemental Indenture thereto, the Second Supplemental Indenture thereto, the Third Supplemental Indenture thereto, the Fourth
Supplemental Indenture thereto, the Fifth Supplemental Indenture thereto, the Sixth Supplemental Indenture thereto, the Seventh Supplemental Indenture and the Eighth Supplemental Indenture thereto, the “Indenture”), among the
Company, Prologis, Inc., as parent guarantor, and U.S. Bank National Association, as trustee (the “Trustee”). Capitalized terms used but not defined in this Officers’ Certificate shall have the meanings ascribed to them in the
Indenture. 
 2.250% Notes due 2029 
 1. The series
shall be entitled the “2.250% Notes due 2029” (the “Notes”) and shall be a series of Sterling Notes as defined in the Eighth Supplemental Indenture. 

2. The Notes initially shall be limited to an aggregate principal amount of £500,000,000 (except in each case for Notes authenticated and delivered upon
registration of transfer of, or in exchange for, or in lieu of, other Notes of or within the Series pursuant to Section 304, 305, 306, 906, 1107 or 1305 of the Base Indenture); provided, the Company may increase such aggregate principal amount
upon the action of the Board to do so from time to time. 
 3. The Notes shall bear interest at the rate of 2.250% per annum. The aggregate principal amount
of the Notes is payable at maturity on June 30, 2029. The interest on this Series shall accrue from and including June 7, 2017 or from and including the most recent Interest Payment Date (as defined below) to which interest has been paid
or duly provided for. Interest on the Notes shall be payable annually in arrears on June 30 of each year (each an “Interest Payment Date”), commencing on June 30, 2018, to persons in whose names the Notes are registered on
the June 15 preceding the Interest Payment Date, whether or not a Business Day (each a “Regular Record Date”). Interest on the Notes shall be computed on the basis of an ACTUAL/ACTUAL (ICMA) (as defined in the rulebook of the
International Capital Markets Association) day count convention. 
 4. The Notes may be surrendered for registration of transfer or exchange and notices or
demands to or upon the Company in respect of the Notes and the Indenture may be served at the Corporate Trust Office of the Paying Agent located at 125 Old Broad Street, London EC2N 1AR, United Kingdom. The principal of the Notes payable at maturity
or upon earlier redemption shall be paid against presentation and surrender of the Notes at the Corporate Trust Office of the Paying Agent. 







 5. The Notes may be redeemed in whole at any time or in part from time to time, at the option of the Company,
upon notice of not more than 60 nor less than 30 days prior to the Redemption Date, at a redemption price (the “Make-Whole Amount”) equal to the greater of 
  

	 	(1)	100% of the principal amount of the Notes to be redeemed; or 

  

	 	(2)	the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (exclusive of interest accrued to, but not including, the Redemption Date) discounted to the
Redemption Date on annual basis (ACTUAL/ACTUAL (ICMA)) at the then applicable Comparable Government Bond Rate plus 20 basis points. 


In each case the Company shall pay accrued and unpaid interest on the principal amount being redeemed to, but not including, the Redemption
Date. 
 The following definitions apply with respect to the Make-Whole Amount: 

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an
Independent Investment Banker, a United Kingdom government bond whose maturity is closest to the maturity of the Notes to be redeemed, or if the Independent Investment Banker in its discretion determines that such similar bond is not in issue, such
other United Kingdom government bond as such Independent Investment Banker may, with the advice of the Reference Bond Dealers, determine to be appropriate for determining the Comparable Government Bond Rate. 

“Comparable Government Bond Rate” means the price, expressed as a percentage (rounded to three decimal places, with 0.0005
being rounded upwards), at which the gross redemption yield on the Notes to be redeemed, if they were to be purchased at such price on the third Business Day prior to the date fixed for redemption, would be equal to the gross redemption yield on
such Business Day of the Comparable Government Bond on the basis of the middle market price of the Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by an Independent Investment Banker. 

“Independent Investment Banker” means one of the Reference Bond Dealers that the Company appoints to act as the Independent
Investment Banker from time to time. 
 “Reference Bond Dealer” means each of HSBC Bank plc, J.P. Morgan Securities plc and
Merrill Lynch International and their successors, and two other firms that are brokers of, and/or market makers in United Kingdom government bonds (each a “Primary Bond Dealer”) which the Company specifies from time to time; provided,
however, that if any of them ceases to be a Primary Bond Dealer, the Company shall substitute another Primary Bond Dealer. 

“sterling” or “£” means the lawful currency of the United Kingdom. 

  
 2 








 In addition, if, as a result of any change in, or amendment to, the laws (or any regulations or
rulings promulgated under the laws) of the United States (or any taxing authority thereof or therein), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which
change or amendment is announced or becomes effective on or after May 31, 2017, the Company becomes or, based upon a written opinion of independent counsel selected by the Company, shall become obligated to pay Additional Amounts with respect
to the Notes, then the Notes may be redeemed at the option of the Company, in whole, but not in part, having given not less than 30 days nor more than 60 days prior notice to the Holders of the Notes, at a redemption price (the “Tax
Redemption Price”) equal to 100% of the principal amount of the Notes being redeemed, together with accrued and unpaid interest thereon, to, but not including, the Redemption Date, all in accordance with the provisions of Article Eleven of
the Base Indenture. 
 If notice of redemption has been given as provided in the Base Indenture and funds for the redemption of any Notes
called for redemption shall have been made available on the Redemption Date referred to in such notice, such Notes shall cease to bear interest on the Redemption Date and the only right of the Holders of the Notes from and after the Redemption Date
shall be to receive payment of the Redemption Price upon surrender of such Notes in accordance with such notice. 
 6. All payments in respect of the Notes
shall be made by or on behalf of the Company without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature, imposed or levied by the United States or any taxing
authority thereof or therein, unless such withholding or deduction is required by law. If such withholding or deduction is required by law, the Company shall pay to a holder who is not a United States person such additional amounts (the
“Additional Amounts”) on the Notes as are necessary in order that the net payment by the Company or the Paying Agent of the principal of, and premium or Redemption Price, if any, and interest on, the Notes to such holder, after such
withholding or deduction, shall not be less than the amount provided in the Notes to be then due and payable; provided, however, that the foregoing obligation to pay Additional Amounts shall not apply: 

(i) to any tax, assessment or other governmental charge that would not have been imposed but for the holder, or a fiduciary, settlor,
beneficiary, member or shareholder of the holder if the holder is an estate, trust, partnership or corporation, or a person holding a power over an estate or trust administered by a fiduciary holder, being considered as: 

(a) being or having been engaged in a trade or business in the United States or having or having had a permanent establishment
in the United States or having or having had a qualified business unit which has the U.S. Dollar as its functional currency; 

(b) having a current or former connection with the United States (other than a connection arising solely as a result of the
ownership of the Notes, the receipt of any payment or the enforcement of any rights thereunder) or being considered as having such relationship, including being or having been a citizen or resident of the United States; 

(c) being or having been a personal holding company, a passive foreign investment company or a controlled foreign corporation
with respect to the United States or a foreign personal holding company that has accumulated earnings to avoid United States federal income tax;

 (d) being or having been an owner of a 10% or greater interest in the capital or
profits of the Company within the meaning of Section 871(h)(3) of the United States Internal Revenue Code of 1986, as amended (the “Code”), or any successor provision; or 

(e) being a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the ordinary
course of its trade or business; 
 (ii) to any Holder that is not the sole beneficial owner of the Notes, or a portion of the Notes, or
that is a fiduciary, partnership or limited liability company, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership or limited liability company would not have been
entitled to the payment of an Additional Amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment; 

(iii) to any tax, assessment or other governmental charge that would not have been imposed but for the failure of the Holder or any other
person to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the Holder or beneficial owner of the Notes, if compliance is required
by statute, by regulation of the United States or any taxing authority therein or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge; 

(iv) to any tax, assessment or other governmental charge that is imposed otherwise than by withholding by the Company or a paying agent from
the payment; 
 (v) to any tax, assessment or other governmental charge that would not have been imposed but for a change in law,
regulation, or administrative or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever occurs later; 

(vi) to any estate, inheritance, gift, sales, excise, transfer, wealth, capital gains or personal property tax or similar tax, assessment or
other governmental charge; 
 (vii) to any withholding or deduction that is imposed on a payment to an individual and that is required to be
made pursuant to any law implementing or complying with, or introduced in order to conform to, any European Union Directive on the taxation of savings; 

(viii) to any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal of or
interest on any Note, if such payment can be made without such withholding by at least one other paying agent; 
 (ix) to any tax,
assessment or other governmental charge that would not have been imposed but for the presentation by the Holder of any Note, where presentation is required, for payment on a date more than 30 days after the date on which payment became due and
payable or the date on which payment thereof is duly provided for, whichever occurs later; 

  
 4 








 (x) to any withholding or deduction that is imposed on a payment pursuant to Sections 1471
through 1474 of the Code and related Treasury regulations, pronouncements relating thereto or official interpretations thereof or any successor provisions, any agreements entered into pursuant to Section 1471(b)(1) of the Code, any applicable
intergovernmental agreement entered into between the United States and any other governmental authority in connection with the implementation of the foregoing and any regulations or official law, agreement or interpretations thereof implementing an
intergovernmental approach thereto; or 
 (xi) in the case of any combination of items (i), (ii), (iii), (iv), (v), (vi), (vii),
(viii), (ix) and (x). 
 The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial
interpretation applicable to the Notes. Except as specifically provided under this Paragraph 6, the Company shall not be required to make any payment for any tax, duty, assessment or governmental charge of whatever nature imposed by any government
or a political subdivision or taxing authority of or in any government or political subdivision. 
 7. The Notes shall not provide for any sinking fund or
analogous provision. None of the Notes shall be redeemable at the option of the Holder. 
 8. The Notes shall be issuable in registered form in the form set
out in Exhibit A of the Eighth Supplemental Indenture without coupons in minimum denominations of £100,000 and any integral multiple of £1,000 in excess thereof. 

9. The principal amount of, and the Make-Whole Amount or Tax Redemption Price, if any, on, the Notes shall be payable upon declaration of acceleration pursuant
to Section 502 of the Base Indenture. 
 10. The Notes shall be denominated in and principal of or interest on the Notes (or Make-Whole Amount,
Redemption Price or Tax Redemption Price, if applicable) shall be payable in sterling. If sterling is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond the Company’s control or for the
settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Notes shall be made in U.S. Dollars until sterling is again available to the Company or so used. In such
circumstances, the amount payable on any date in sterling shall be converted into U.S. Dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant
payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. Dollar/sterling exchange rate published in The Wall Street Journal on or prior to the second
Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate shall be determined in the Company’s sole discretion on the basis of the most recently available market
exchange rate for sterling. Any payment in respect of the Notes so made in U.S. Dollars shall not constitute an Event of Default. Neither the Trustee nor the Paying Agent shall be responsible for obtaining exchange rates, effecting conversions or
otherwise handling redenominations.

stated to be payable.
