ROCKWELL AUTOMATION, INC.

1.750% Note due August 15, 2031

This Security is one of a duly authorized issue of Securities of the Company designated as its 1.750% Notes due August 15, 2031 (Securities of such series being hereinafter called the “Securities”), initially issued in an aggregate principal amount of $[•], issued under an Indenture dated as of December 1, 1996 (hereinafter called the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A., as successor to Mellon Bank, N.A.), as Trustee (hereinafter called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the Securities of this series), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and any Holder of the Securities, and the terms upon which the Securities are, and are to be, authenticated and delivered.

Except as set forth below, this Security will be issued in global form only registered in the name of the Depositary or its nominee. Except as set forth below, this Security will not be issued in definitive form, and ownership of this Security shall be maintained in book-entry form by the Depositary for the accounts of participating organizations of the Depositary.

The Depositary for the Securities shall initially be The Depository Trust Company. If the Depositary is at any time unwilling, unable or ineligible to continue as Depository for the Securities and the Company does not appoint a successor Depository within 90 days, the Company will issue Securities in definitive form to participants of the Depositary in exchange for the Global Security representing the Securities. In addition, the Company may, at any time and in its sole discretion, determine not to have any Securities represented in global form. In that event, the Company will issue Securities in definitive form to participants of the Depositary in exchange for the Global Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin and currency, herein prescribed.

This Security is not entitled to the benefit of a sinking fund or any analogous provision. Securities will be redeemable as a whole at any time or in part from time to time prior to May 15, 2031, at the option of the Company, on not less than 10 or more than 60 days’ notice mailed to Holders thereof, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities being redeemed and (ii) as determined by the Quotation Agent (as defined below), the sum of the present values of the Remaining Scheduled Payments (as defined below) of the Securities being redeemed as if such Securities matured on May 15, 2031 (excluding interest accrued as of the

Redemption Date), discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 10 basis points, together, in each case, with accrued interest on the principal amount at Maturity being redeemed to the date of redemption. Securities will be redeemable as a whole at any time or in part from time to time on or after May 15, 2031, at the option of the Company, on not less than 10 or more than 60 days’ notice mailed to Holders thereof, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed, together with accrued interest on the principal amount being redeemed to the date of redemption.

The covenant contained in Section 11.05 (Notice of Redemption) of the Indenture is modified with respect to the Securities such that each reference therein to “not less than 30 nor more than 60 days prior to the Redemption Date” shall be replaced with “not less than 10 nor more than 60 days prior to the Redemption Date”.

If (i) the consummation of the Plex Acquisition does not occur on or before 5:00 p.m. New York City time on January 31, 2022, (ii) the Company notifies the Trustee and the Holders of the Securities that the Company will not pursue the consummation of the Plex Acquisition or (iii) the Merger Agreement has been terminated without the consummation of the Plex Acquisition (each of (i), (ii) and (iii), a “Special Mandatory Redemption Trigger”), the Company will be required to redeem the Securities then outstanding (such redemption, the “Special Mandatory Redemption”) at a redemption price equal to 101% of the principal amount of such Securities plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”).

In the event that the Company becomes obligated to redeem the Securities pursuant to the Special Mandatory Redemption, the Company will promptly, and in any event not more than two business days after the date on which a Special Mandatory Redemption Trigger occurred, deliver notice to the Trustee and the Holders of the Securities of the Special Mandatory Redemption and the date upon which the Securities will be redeemed (the “Special Mandatory Redemption Date,” which date shall be on or about the fifth business day following the date of such notice) together with a notice of Special Mandatory Redemption for the Trustee to deliver to each registered Holder of the Securities to be redeemed. At the Company’s request, given at least two business days before such notice is to be sent, the Trustee will promptly mail, or electronically deliver, according to the procedures of DTC, such notice of Special Mandatory Redemption to each registered Holder of the Securities to be redeemed. Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the notes to be redeemed.

Notwithstanding the foregoing, installments of interest on the Securities are due and payable on interest payment dates falling on or prior to the Special Mandatory Redemption Date will be payable on such interest payment dates to the registered Holders as of the close of business on the relevant record dates in accordance with such notes and the indenture.

R-2

“Comparable Treasury Issue” means the United States Treasury Security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Securities to be redeemed (assuming for this purpose, that such notes matured on May 15, 2031) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities.

“Comparable Treasury Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains fewer than three such Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations.

LLC, Loop Capital Markets LLC and Wells Fargo Securities, LLC and their respective successors; provided, however, that if any of the foregoing ceases to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer as of 5:00 p.m., New York City time, on the third business day immediately preceding such Redemption Date.

“Remaining Scheduled Payments” means, with respect to each Security to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date but for such redemption assuming, for this purpose, that such notes matured on the applicable par call date; provided, however, that if such Redemption Date is not an Interest Payment Date with respect to such Security, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such Redemption Date.

R-3

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding such Redemption Date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or any portion thereof called for redemption. On or before any Redemption Date, the Company shall deposit with a Paying Agent (or the Trustee) money sufficient to pay the Redemption Price of and accrued interest on the Securities to be redeemed on such date. If less than all the Securities are to be redeemed, the Securities to be redeemed shall be selected by the Trustee in compliance with the requirements governing redemptions of the principal securities exchange, if any, on which the Securities are listed or if such securities exchange has no requirement governing redemption or the Securities are not then listed on a securities exchange, by any method as may be required by the Depositary in accordance with its applicable procedures.

“Change of Control” means the occurrence of any of the following: (i) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the Company and its Subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its Subsidiaries; (ii) the adoption of a plan relating to the Company’s liquidation or dissolution; or (iii) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) or group of persons, other than the Company or its Subsidiaries, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Company’s Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares.

As provided in the Indenture and subject to certain limitations therein set forth, this Security may be registered for transfer on the Security Register of the Company, upon surrender of this Security for registration of transfer at the office or agency of the Company in the Place of Payment, and at such other locations as the Company may from time to time designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder hereof or the Holder’s attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities are issuable only as Registered Securities without coupons in the denominations of $2,000 and any higher integral multiple of $1,000. As provided in the Indenture, and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of different authorized denominations, as requested by the Holder surrendering the same.

No service charge will be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment for registration of transfer of this Security, the Company, the Trustee, the Security Registrar, the Paying Agent and any agent of any one thereof may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee, the Security Registrar, the Paying Agent nor any such agent shall be affected by notice to the contrary.

If an Event of Default, with respect to the Securities shall occur, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not a notation of such consent or waiver is made upon this Security.

R-7

The Company at its option, subject to the terms and conditions contained in the Indenture, (a) will be discharged from any and all obligations in respect of the Securities (except for certain obligations to register the transfer and exchange of such Securities, to replace mutilated, destroyed, lost or stolen Securities, to compensate, reimburse and indemnify the Trustee, to maintain an office or agency with respect to the Securities and to hold moneys for payment in trust) or (b) may omit to comply with certain restrictive covenants contained in the Indenture, in each case upon irrevocable deposit with the Trustee in trust of money or U.S. government securities (as described in the Indenture) or a combination thereof, which through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to discharge the principal of and interest on such Securities on the Stated Maturity of such principal or interest.

Except as otherwise defined herein, all terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
