JOHNSON CONTROLS INTERNATIONAL PLC

TYCO FIRE & SECURITY FINANCE S.C.A.

$250,000,000 4.900% Senior Notes due 2032

Johnson Controls International plc (the “Company”) and Tyco Fire & Security Finance S.C.A., a wholly owned subsidiary of the Company (the “Co-Issuer” and together with the Company, the “Issuers”), are offering $250,000,000 aggregate principal amount of 4.900% Senior Notes due 2032 (the “New Notes”). The New Notes are being offered as additional notes under the Indenture (as defined herein) pursuant to which the Issuers previously issued $400,000,000 aggregate principal amount of their 4.900% Senior Notes due 2032 on September 14, 2022 (the “Initial Notes” and, together with the New Notes, the “Notes”). The Issuers will pay interest on the New Notes semi-annually in arrears on June 1 and December 1 of each year, beginning June 1, 2025.

The Notes bear interest at a rate of 4.900% per annum and will mature on December 1, 2032, unless previously redeemed as described below. See “Description of Notes—Maturity and Interest.”

The Issuers may redeem some or all of the Notes at the redemption price set forth in this prospectus supplement, plus accrued and unpaid interest, if any, thereon to, but excluding, the redemption date. In addition, we may, at our option, redeem all, but not less than all, of the Notes at any time upon the occurrence of specified tax events as described herein. If we experience a Change of Control Triggering Event (as defined herein), unless we have exercised our right to redeem the Notes or have defeased the Notes as described herein, we will be required to offer to purchase the Notes from holders. See “Description of Notes—Offer to Repurchase Upon Change of Control Triggering Event.”

The New Notes offered hereby will have the same terms (other than the issue price, issue date and initial interest payment date) as, will vote together as a single class with, and will have the same CUSIP/ISIN numbers as, and be fungible for U.S. federal income tax purposes with, the Initial Notes. Upon completion of this offering, the aggregate principal amount of the Notes, assuming all New Notes offered hereby are sold, will be $650,000,000.

The Initial Notes are listed for trading on the New York Stock Exchange and we intend to list the New Notes on the New York Stock Exchange. Trading in the New Notes is expected to begin within 30 days of the issue date of the New Notes. If such a listing is obtained, we will have no obligation to maintain such listing, and we may delist the Notes at any time.

The Notes are the Issuers’ unsecured, unsubordinated obligations. The Notes rank senior in right of payment to the Issuers’ existing and future indebtedness and other obligations that are expressly subordinated in right of payment to the Notes; equal in right of payment to the Issuers’ existing and future indebtedness and other obligations that are not so subordinated; effectively junior to any of the Issuers’ secured indebtedness and other obligations to the extent of the value of the assets securing such indebtedness or other obligations; and structurally junior to all existing and future indebtedness and other obligations incurred by the Issuers’ subsidiaries. The New Notes will be issued only in minimum denominations of $2,000 and whole multiples of $1,000 in excess thereof.

Investing in the New Notes involves risks. See “Risk Factors” beginning on page S-9 of this prospectus supplement for important factors you should consider before investing in the New Notes.

FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus or any document incorporated by reference into this prospectus supplement or the accompanying prospectus may contain statements that are forward-looking and therefore are subject to risks and uncertainties. All statements other than statements of historical fact are or could be “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Statements regarding Johnson Controls’ future financial position, sales, costs, earnings, cash flows, other measures of results of operations, synergies and integration opportunities, capital expenditures and debt levels are forward-looking statements. Words such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “should,” “forecast,” “project” or “plan” and terms of similar meaning are also generally intended to identify forward-looking statements. However, the absence of these words does not mean that a statement is not forward-looking. Johnson Controls cautions that these statements are subject to numerous important risks, uncertainties, assumptions and other factors, some of which are beyond Johnson Controls’ control, that could cause Johnson Controls’ actual results to differ materially from those expressed or implied by such forward-looking statements. Investors are therefore cautioned not to place undue reliance on any forward-looking statements. The forward-looking statements included are made only as of the date of the document in which they are included, unless otherwise specified, and, except as required by law, Johnson Controls assumes no obligation, and disclaims any obligation, to update forward-looking statements to reflect events or circumstances occurring after the date of such document.

The following are some important factors that could cause the actual results of Johnson Controls to differ from its current expectations:

S-v

The foregoing list sets forth many, but not all, of the factors that could impact Johnson Controls’ ability to achieve results described in any forward-looking statements. See also the factors set forth under “Risk Factors” in this prospectus supplement and in Item 1A of Johnson Controls’ most recent Annual Report on Form 10-K for the fiscal year ended September 30, 2024 filed with the SEC on November 19, 2024, which is incorporated by reference in this prospectus supplement and the accompanying prospectus.

Investors should understand that it is not possible to predict or identify all such factors and should not consider this list to be a complete statement of all potential risks and uncertainties.

RISK FACTORS

Investing in the New Notes involves various risks, including the risks described below. The risks described below are not the only ones facing us. Our business also is subject to the risks that affect many other companies, such as competition, technological obsolescence, labor relations, general economic conditions, geopolitical events, climate change and international operations. Additional risks not currently known to us or that we currently believe are immaterial also may impair our business operations and our liquidity. You should carefully consider the following risks and the risks set forth under the caption “Risk Factors” in Johnson Controls’ Annual Report on Form 10-K for the fiscal year ended September 30, 2024, which is incorporated by reference herein, before investing in the Notes.

Risks Related to the Notes

The Notes are effectively junior to all of the Issuers’ secured obligations and to the obligations of subsidiaries of JCI plc (other than TFSCA).

The Notes rank senior in right of payment to the Issuers’ existing and future indebtedness and other obligations that are expressly subordinated in right of payment to the Notes; equal in right of payment to the Issuers’ existing and future indebtedness and other obligations that are not so subordinated; effectively junior to any of the Issuers’ secured indebtedness and other obligations to the extent of the value of the assets securing such indebtedness or other obligations; and structurally junior to all existing and future indebtedness and other obligations incurred by subsidiaries of JCI plc (other than TFSCA).

As such, in the event of a bankruptcy, examination, liquidation, administration, dissolution, reorganization or similar proceeding involving the Issuers or any of their subsidiaries, the assets of the affected entity could not be used to pay you until after:

Holders of the Notes will participate ratably in Johnson Controls’ remaining assets with all holders of its other unsecured, unsubordinated debt that is deemed to be of the same class as the Notes and potentially with all of its other general creditors based upon the respective amounts owed to each holder or creditor. If any of the foregoing events were to occur, the Issuers cannot assure you that there will be sufficient assets to pay amounts due on the Notes. As a result, the holders of the Notes may receive less, ratably, than the holders of secured debt or holders of indebtedness of its subsidiaries.

As of September 30, 2024, Johnson Controls had outstanding, on a consolidated basis, approximately $9,493 million of total debt, $233 million of which constituted debt of the subsidiaries of the consolidated company (excluding TFSCA). The Notes are structurally subordinated to the debt of the subsidiaries of the consolidated company other than TFSCA.

As of September 30, 2024, Johnson Controls had no secured indebtedness outstanding.

The Issuers are not restricted under the terms of the Indenture or the Notes from incurring additional indebtedness. The terms of the Indenture limit Johnson Controls’ ability to secure additional debt without also securing the Notes and to enter into sale and leaseback transactions. However, these limitations are subject to numerous exceptions.

The Notes are obligations of the Issuers only, but the Issuers’ operations are conducted through, and a substantial portion of the Issuers’ consolidated assets are held by, their subsidiaries.

The Notes are obligations of the Issuers only. A substantial portion of the Issuers’ consolidated assets are held by their subsidiaries, which means that the Issuers’ ability to service their debt, including the Notes, depends

S-9

on the results of operations of their subsidiaries and upon the ability of those subsidiaries to provide the Issuers with cash, whether in the form of dividends, loans or otherwise, to pay amounts due on the Issuers’ obligations, including the Notes. The Issuers’ subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make payments on the Notes or to make any funds available for that purpose. In addition, dividends, loans or other distributions to the Issuers from such subsidiaries may be subject to contractual and other restrictions and are subject to other business considerations.

Despite Johnson Controls’ current debt levels, Johnson Controls may still incur substantially more debt or take other actions which would intensify the risks discussed above.

Despite Johnson Controls’ current debt levels, Johnson Controls and its subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in Johnson Controls’ debt agreements, some of which may be secured debt. Johnson Controls is not restricted under the terms of the Indenture or the Notes from incurring additional indebtedness. Johnson Controls also continually evaluates market conditions and intends to be opportunistic in refinancing a portion of its upcoming short term maturities.

The terms of the Indenture limit Johnson Controls’ ability to secure additional debt without also securing the Notes and to enter into sale and leaseback transactions. However, these limitations apply only to principal property (of which Johnson Controls believes it currently has none), and are subject to numerous significant exceptions. In addition, the Notes do not require Johnson Controls to achieve or maintain any minimum financial results relating to its financial position or results of operations. Johnson Controls’ ability to recapitalize, incur additional debt, secure existing or future debt or take a number of other actions that are not limited by the terms of the Indenture and the Notes could have the effect of diminishing the Issuers’ ability to make payments on the Notes when due, causing a loss in the trading value of your Notes, and increasing the risk that the credit rating of the Notes is lowered or withdrawn.

Johnson Controls’ credit ratings may not reflect all risks of your investment in the New Notes.

The credit ratings assigned to the New Notes are limited in scope, and do not address all material risks relating to an investment in the New Notes, but rather reflect only the view of each rating agency at the time the rating is issued. There can be no assurance that those credit ratings will remain in effect for any given period of time or that a rating will not be lowered, suspended or withdrawn entirely by one or more rating agencies if, in that rating agency’s judgment, circumstances so warrant.

Agency credit ratings are not a recommendation to buy, sell or hold any security. Each agency’s rating should be evaluated independently of any other agency’s rating. Actual or anticipated changes or downgrades in Johnson Controls’ credit ratings, including any announcement that its ratings are under further review for a downgrade, could affect the market value of the New Notes and increase its corporate borrowing costs.

There are limited covenants in the Indenture.

Neither the Issuers nor any of their subsidiaries are restricted under the terms of the Indenture or the Notes from incurring additional debt or other liabilities. If the Issuers or their subsidiaries incur additional debt or liabilities, the Issuers’ ability to pay their obligations on the Notes, and the ability of the Issuers’ subsidiaries to fund such payments on behalf of the Issuers, could be adversely affected. Johnson Controls expects that it will from time to time incur additional debt and other liabilities.

In addition, (i) the Issuers and their subsidiaries are not restricted under the Indenture from granting security interests over their respective assets, except to the extent described under “Description of Notes—Certain Covenants—Limitation on Liens” in this prospectus supplement, or from paying dividends, making investments or issuing or repurchasing their respective securities, and (ii) there are no financial covenants in the Indenture. You are not protected under the Indenture in the event of a highly leveraged transaction, reorganization, restructuring, merger or similar transaction that may adversely affect you.

S-10

Furthermore, although the Issuers are required under certain circumstances to make additional payments to holders as a result of tax withholdings or deductions, such obligations are subject to certain important exceptions as described under “Description of Notes—Payment of Additional Amounts,” including with respect to taxes imposed by or on behalf of the United States. Prospective holders of the New Notes are advised to seek their own professional advice in relation to any such risk.

Servicing Johnson Controls’ debt requires a significant amount of cash, and Johnson Controls may not have sufficient cash flow from its business to pay its substantial debt.

Johnson Controls’ ability to make scheduled payments of the principal of, to pay interest on or to refinance its indebtedness, including the New Notes offered hereby, depends on its future performance, which is subject to economic, financial, competitive and other factors beyond its control. Johnson Controls’ business may not continue to generate cash flow from operations in the future sufficient to service its debt and make necessary capital expenditures. If Johnson Controls is unable to generate such cash flow, it may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Johnson Controls’ ability to refinance its indebtedness will depend on the capital markets and its financial condition at that time, including interest rates, the stability of financial institutions with which Johnson Controls partners, the liquidity of the overall global capital markets and the state of the global economy. Johnson Controls may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on its debt obligations.

You may not be able to sell your Notes if active trading markets for the Notes is not maintained.

The Initial Notes are listed on the New York Stock Exchange. Johnson Controls intends to list the New Notes on the New York Stock Exchange. However, Johnson Controls cannot provide you with any assurance regarding whether active trading markets for the Notes will be maintained, the ability of holders of the Notes to sell their Notes or the prices at which holders may be able to sell their Notes. In addition, even if the listing of the New Notes on the New York Stock Exchange is obtained, Johnson Controls will have no obligation to maintain such listing, and we may delist the Notes at any time.

The price at which you will be able to sell your New Notes prior to maturity will depend on a number of factors.

Johnson Controls believes that the value of the New Notes in any secondary market that may develop will be affected by the supply of, and demand for, the New Notes together with the Initial Notes, interest rates and a number of other factors. Some of these factors are interrelated in complex ways. As a result, the effect of any one factor may be offset or magnified by the effect of another factor. The following paragraphs describe what Johnson Controls expects to be the impact on the market value of the New Notes of a change in a specific factor, assuming all other conditions remain constant.

S-11

Johnson Controls may not be able to repurchase all of the Notes upon a Change of Control Triggering Event.

As described under “Description of Notes—Offer to Repurchase Upon Change of Control Triggering Event,” Johnson Controls will be required to offer to purchase the Notes upon the occurrence of a Change of Control Triggering Event. Johnson Controls may not have sufficient funds to purchase the Notes at that time or have the ability to arrange financing on acceptable terms. If we are unable to purchase the Notes as required upon the occurrence of a Change of Control Triggering Event, it would result in a default under the Indenture. A default under the Indenture could also lead to a default under the agreements governing our existing or future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and purchase the Notes being repurchased.

Redemption may adversely affect your return on the Notes.

Johnson Controls has the right to redeem some or all of the Notes prior to maturity, as described under “Description of Notes—Optional Redemption.” Johnson Controls may redeem the Notes at times when prevailing interest rates may be relatively low. Accordingly, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of the Notes.

In the event interest paid on the Notes is treated as U.S. source interest, a non-U.S. beneficial owner may be subject to a 30% U.S. withholding tax unless the beneficial owner qualifies for an exemption.

In the event that either Issuer, or any successor thereto, is or becomes domiciled in the United States, or the Notes otherwise became subject to U.S. federal withholding tax, a beneficial owner of a Note that is not a U.S. Holder (as defined in “—Certain U.S. Federal Income Tax Considerations”) may be subject to withholding tax at a rate of 30% (or a lower treaty rate) unless the beneficial owner qualifies for an applicable exemption from U.S. withholding tax on payments of interest. We will not be required to pay any additional amounts with respect to amounts so withheld.

The Proposed Financial Transaction Tax (“FTT”) remains uncertain and could, if introduced, apply to certain dealings in the Notes (including secondary market transactions) in certain circumstances.

On February 14, 2013, the European Commission published a proposal (the “Commission’s Proposal”) for a Directive for a common FTT in Belgium, Germany, Estonia, Greece, Spain, France, Italy, Austria, Portugal,

S-12

Slovenia and Slovakia (the “participating Member States” although Estonia has since stated that it will not participate).

Under the Commission’s Proposal, the FTT could apply in certain circumstances to persons both within and outside of the participating Member States. Generally, it would apply to certain dealings in the Notes where at least one party is a financial institution, and at least one party is established in a participating Member State. A financial institution may be, or be deemed to be, “established” in a participating Member State in a broad range of circumstances, including (a) by transacting with a person established in a participating Member State or (b) where the financial instrument which is subject to the dealings is issued in a participating Member State.

However, the FTT proposal remains subject to negotiation between the participating Member States and the scope of any such tax is uncertain. It may therefore be altered prior to any implementation, the timing of which remains unclear. Additional EU Member States may decide to participate. Prospective holders of the New Notes are advised to seek their own professional advice in relation to the FTT.

The insolvency laws of Luxembourg and/or Ireland may not be as favorable to you as the U.S. bankruptcy laws and may preclude holders of the Notes from recovering payments due on the Notes.

JCI plc is incorporated under the laws of Ireland and TFSCA is incorporated and organized under the laws of Luxembourg. In the event of a bankruptcy, insolvency, reorganization or similar event, proceedings, including winding-up proceedings, could be initiated in Luxembourg and/or Ireland. The bankruptcy, insolvency, administrative, debtor relief and other laws of Luxembourg or Ireland, as applicable, may be materially different from, or in conflict with, those of the United States, including in the areas of rights of creditors, priority of governmental and other creditors, ability to obtain post-petition interest and duration of the proceeding. The application of these laws, or any conflict among them, could adversely affect your ability to enforce your rights under the New Notes in those jurisdictions or limit any amounts that you may receive.

The Issuers may be adversely affected by anti-tax avoidance directives adopted by European Union Member States.

Directive 2016/1164/EU, called the anti-tax avoidance directive (“ATAD”), was adopted on July 12, 2016 to implement in the EU Member States’ domestic legal frameworks common measures to tackle tax avoidance practices. ATAD lays down (i) controlled foreign company rules, (ii) anti-hybrid mismatches within the EU context rules, (iii) general interest limitation rules, (iv) a general anti-abuse rule, and (v) exit taxation rules.

Following the adoption of ATAD, the EU Member States decided to go further as regards to hybrid-mismatches with third countries, and adopted the Directive 2017/952/EU (“ATAD 2”) amending the ATAD provisions with respect to anti-hybrid mismatches, on May 29, 2017.

EU Member States had until December 31, 2018 to implement ATAD (subject to derogations for EU Member States which had equivalent measures in their domestic law) and had until December 31, 2019 to implement ATAD 2 (except for measures relating to reverse hybrid mismatches, which had to be implemented by December 31, 2021).

Luxembourg adopted (i) the Law of December 21, 2018 implementing ATAD with effect as of January 1, 2019 and (ii) the Law of December 20, 2019 implementing ATAD 2 with effect as of January 1, 2020 (except for the reverse hybrid mismatch rules, which apply as of January 1, 2022). These rules could increase the Co-Issuer’s taxable base and may result in adverse financial impacts to the Co-Issuer.

Ireland has implemented ATAD and ATAD 2, including the interest limitation rules which restrict the deductibility of an entity’s “exceeding borrowing costs” to the higher of (a) €3.0 million or (b) 30% of its EBITDA (earnings before interest, tax, depreciation and amortization) in the year in which they are incurred but the balance would remain available for carry forward, subject to certain conditions.

S-13

For these purposes, “exceeding borrowing costs” means the amount by which an entity’s borrowing costs exceeds its taxable interest revenues and other economically equivalent taxable revenues. For example, where the Company funds interest payments it makes under the Notes from payments it receives as part of its day to day activities which are interest or “interest equivalent” (as defined in the implementing legislation), then the Company should not have any exceeding borrowing costs and so the rules may have not have a significant impact on the Company.

If the Company’s “exceeding borrowing costs” do not exceed €3.0 million, then the entity would fall outside the interest limitation rule even where the rule would normally apply. If the Company has “exceeding borrowing costs” in excess of €3.0 million in a tax year and its ability to deduct interest in that tax year is restricted by Ireland’s interest limitation rule, the Company may have material tax liabilities in Ireland as a consequence of this interest not being deductible in computing its profits for Irish corporation tax purposes.

S-14

USE OF PROCEEDS

Johnson Controls estimates that the net proceeds from the New Notes offered hereby will be approximately $246.5 million after deducting the underwriting discount and estimated offering expenses. We intend to use the net proceeds from the sale of the New Notes for general corporate purposes, including the repayment, redemption or refinancing of outstanding commercial paper and other near-term indebtedness. General corporate purposes may also include acquisitions, additions to working capital, repurchase of ordinary shares, dividends, capital expenditures and investments in our subsidiaries. Pending such use, the net proceeds may be invested in short-term, investment-grade, interest-bearing securities, certificates of deposit or indirect or guaranteed obligations of the United States.

S-15

CAPITALIZATION

The following table sets forth, as of September 30, 2024, our consolidated cash and cash equivalents and total capitalization:

You should read the table in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and the notes thereto which are included in Johnson Controls’ Annual Report on Form 10-K for the year ended September 30, 2024 filed with the SEC on November 19, 2024, which is incorporated by reference in this prospectus supplement and the accompanying prospectus.

S-16

DESCRIPTION OF NOTES

Capitalized terms used in this “Description of Notes” section and not otherwise defined have the meanings set forth under the heading “—Definitions” below. For purposes of this “Description of Notes” section, (a) the terms “JCI plc” or “Company” refer only to Johnson Controls International plc, a public limited company incorporated under the laws of Ireland, and its successors permitted by the terms of the Indenture (b) the terms “TFSCA” or “Co-Issuer” refer to Tyco Fire & Security Finance S.C.A., a corporate partnership limited by shares incorporated and organized under the laws of the Grand Duchy of Luxembourg, and its successors permitted by the terms of the Indenture, (c) the terms “Issuers,” “we,” “us” and “our” refer to JCI plc and TFSCA together, and (d) the term “Johnson Controls” refers to JCI plc and its consolidated subsidiaries, including TFSCA.

We are offering $250,000,000 initial aggregate principal amount of our 4.900% Senior Notes due 2032 (the “New Notes”). We previously issued $400,000,000 aggregate principal amount of 4.900% Senior Notes due 2032 on September 14, 2022 (the “Initial Notes” and, together with the New Notes, the “Notes”). Unless the context requires otherwise, for all purposes of the Indenture (as defined below) and this “Description of Notes,” references to the Notes include the New Notes offered hereby and the Initial Notes. The following description supplements, and to the extent it is inconsistent with replaces, the description of the general terms and provisions contained in “Description of Debt Securities” in the accompanying prospectus.

The New Notes offered hereby will form a part of the same series and will have the same terms (other than the issue price, issue date and initial interest payment date) as, will vote together as a single class with, and will have the same CUSIP/ISIN numbers as, and be fungible for U.S. federal income tax purposes with, the Initial Notes. Upon completion of this offering, the aggregate principal amount of the Notes, assuming all New Notes offered hereby are sold, will be $650,000,000.

The Initial Notes were issued under the Indenture, dated as of December 28, 2016 (the “Base Indenture”), between JCI plc and U.S. Bank Trust Company, National Association (successor in interest to U.S. Bank National Association), as trustee (the “Trustee”) and a Ninth Supplemental Indenture, dated as of September 14, 2022, entered into among JCI plc, TFSCA and the Trustee (the “Ninth Supplemental Indenture”). The New Notes will be issued under the Base Indenture and the Ninth Supplemental Indenture as further amended or supplemented by the Twelfth Supplemental Indenture relating to the New Notes to be entered into among JCI plc, TFSCA and the Trustee (together with the Base Indenture and the Ninth Supplemental Indenture, the “Indenture”). The terms of the New Notes will include those expressly set forth in such notes and the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§77aaa-77bbbb), as in effect from time to time (the “Trust Indenture Act”).

The Issuers are jointly and severally liable for all obligations under the Notes. The Co-Issuer is a wholly-owned consolidated subsidiary of the Company that is 99.924% owned directly by the Company and 0.076% owned by TFSCA’s sole general partner and manager, Tyco Fire & Security S.à r.l., which is itself wholly owned by the Company. The Co-Issuer is a holding company that directly and indirectly holds substantially all of the subsidiaries of JCI plc. The Co-Issuer engages in intercompany financial services on behalf of JCI plc, including engaging in intercompany loan transactions and engaging in currency hedging transactions on behalf of JCI plc and its subsidiaries.

This description is a summary of the material provisions of the Notes and the Indenture. This description does not restate those agreements and instruments in their entirety. We urge you to read the Notes and the Indenture because they, not the summaries below and in the accompanying prospectus, will define the rights of holders of the Notes.

General

The Notes are JCI plc’s and the Co-Issuer’s unsecured, unsubordinated obligations. The Notes rank senior in right of payment to JCI plc’s and the Co-Issuer’s existing and future indebtedness and other obligations that are

S-17

expressly subordinated in right of payment to the Notes; equal in right of payment to JCI plc’s and the Co-Issuer’s existing and future indebtedness and other obligations that are not so subordinated; effectively junior to any of JCI plc’s and the Co-Issuer’s secured indebtedness and other obligations to the extent of the value of the assets securing such indebtedness or other obligations; and structurally junior to all existing and future indebtedness and other obligations incurred by JCI plc’s and the Co-Issuer’s subsidiaries. TFSCA is not a co-issuer in respect of JCI plc’s outstanding senior notes other than the 0.375% Senior Notes due 2027, 3.000% Senior Notes due 2028, 5.500% Senior Notes due 2029, 1.750% Senior Notes due 2030, 2.000% Sustainability-Linked Senior Notes due 2031, 1.000% Senior Notes due 2032 and 4.250% Senior Notes due 2035.

As of September 30, 2024, Johnson Controls had outstanding, on a consolidated basis, approximately $9,493 million of total debt, $233 million of which constituted debt of the subsidiaries of the consolidated company, excluding TFSCA. The Notes are structurally subordinated to the debt of the subsidiaries of the consolidated company other than TFSCA.

As of September 30, 2024, Johnson Controls had no secured indebtedness outstanding.

The New Notes will be issued in book-entry form, represented by one or more Global Securities (as defined below), and delivered through the facilities of DTC.

The New Notes will be issued in registered form without interest coupons and only in minimum denominations of $2,000 and whole multiples of $1,000 in excess thereof.

Maturity and Interest

The Notes will mature on December 1, 2032 and will bear interest at a rate of 4.900% per annum. The date from which interest will accrue on the New Notes will be December 1, 2024. Interest in respect of the New Notes shall be payable semi-annually in arrears on June 1 and December 1 of each year, beginning on June 1, 2025, to the applicable holders of record at the close of business on the May 15 and November 15 next preceding such interest payment date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Except as provided below, the Notes shall not be subject to redemption, repurchase or repayment at the option of any holder thereof, upon the occurrence of any particular circumstance or otherwise. The Notes will not have the benefit of any sinking fund. The Notes will not be convertible into or exchangeable for shares or other securities of the Issuers.

For the avoidance of doubt, articles 470-1 to 470-19 of the Luxembourg law of 10 August 1915 relating to commercial companies, as amended, do not apply to the Notes.

Indenture May Be Used for Future Issuances

We may, without the consent of the then existing holders of the Notes, “re-open” and issue additional Notes, which additional Notes will have the same terms as the Initial Notes and the New Notes offered hereby except for the issue price, issue date and, under some circumstances, the first interest payment date; provided that, if such additional Notes are not fungible with the Initial Notes and the New Notes for U.S. federal income tax purposes, such additional Notes will have a separate CUSIP, ISIN and/or other identifying number from the Initial Notes and the New Notes. Notes issued in this manner will form a single series with the Initial Notes and the New Notes offered hereby.

In addition, the Indenture does not limit the amount of debt securities that can be issued thereunder and provides that debt securities of any series may be issued thereunder up to the aggregate principal amount that we may authorize from time to time. All debt securities issued as a series, including those issued pursuant to any

S-18

reopening of a series, will vote together as a single class. Debt securities issued pursuant to the Indenture may have terms that differ from those of the Notes offered hereby, as set forth in Section 2.01 of the Indenture.

Optional Redemption

Prior to September 1, 2032 (three months prior to the maturity date of the Notes) (the “Par Call Date”), the Issuers may, at their option, redeem the Notes, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) as determined by the Quotation Agent and delivered to the Trustee in writing, the sum of the present values of the remaining scheduled payments of principal and interest thereon that would be due if the Notes matured on the Par Call Date (exclusive of interest accrued to the redemption date), discounted to the redemption date (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Redemption Treasury Rate plus 30 basis points, plus, in either case, accrued and unpaid interest, if any, thereon to, but excluding, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

On or after the Par Call Date, the Issuers may, at their option, redeem the Notes, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, thereon to, but excluding, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

“Adjusted Redemption Treasury Rate” means, with respect to any redemption date for the Notes, the rate equal to the semiannual equivalent yield to maturity or interpolated (on a 30/360 day count basis) yield to maturity of the Comparable Redemption Treasury Issue, assuming a price for the Comparable Redemption Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Redemption Treasury Price for such redemption date.

“Comparable Redemption Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes to be redeemed if the Notes matured on the Par Call Date 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 such remaining term of the Notes.

“Comparable Redemption Treasury Price,” with respect to any redemption date for the Notes, means (i) the average of the Redemption Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Redemption Reference Treasury Dealer Quotations (unless there is more than one highest or lowest quotation, in which case only one such highest and/or lowest quotation shall be excluded), or (ii) if the Quotation Agent obtains fewer than four such Redemption Reference Treasury Dealer Quotations, the average of all such Redemption Reference Treasury Dealer Quotations.

“Independent Investment Banker” means one of the Redemption Reference Treasury Dealers appointed by JCI plc.

“Quotation Agent” means a Redemption Reference Treasury Dealer appointed as such by JCI plc.

“Redemption Reference Treasury Dealer” means (1) each of J.P. Morgan Securities LLC, BofA Securities, Inc. and Morgan Stanley & Co. LLC (or their respective Affiliates that are Primary Treasury Dealers (as defined below)) and their respective successors and (2) two other Primary Treasury Dealers selected by JCI plc after consultation with the Independent Investment Banker; provided, however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer in New York City (a “Primary Treasury Dealer”), JCI plc will substitute therefor another Primary Treasury Dealer.

S-19

“Redemption Reference Treasury Dealer Quotations,” with respect to each Redemption Reference Treasury Dealer and any redemption date for the Notes, means the average, as determined by the Quotation Agent, of the bid and offer prices at 11:00 a.m., New York City time, for the Comparable Redemption Treasury Issue (expressed in each case as a percentage of its principal amount) for settlement on the redemption date quoted in writing to the Quotation Agent by such Redemption Reference Treasury Dealer on the third business day preceding such redemption date.

Redemption Upon Changes in Withholding Taxes

Either or both of the Issuers may redeem all, but not less than all, of the Notes under the following conditions:

Upon the occurrence of each of the bullet points above, the relevant Issuer (or Issuers) may redeem the Notes at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, thereon to, but excluding, the redemption date and all Additional Amounts (if any) then due and that will become due on such redemption date as a result of the redemption or otherwise (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is prior to the redemption date and Additional Amounts (if any) in respect thereof).

The foregoing provisions shall apply mutatis mutandis to any Successor Company or Successor Co-Issuer (each as defined below).

Notice of Redemption

Notice of any redemption will be mailed, or delivered electronically if the Notes to be redeemed are held by any depositary, at least 10 days but not more than 90 days before the date fixed for such redemption to each holder of Notes to be redeemed. If less than all of the Notes are to be redeemed, the Trustee will select the

S-20

outstanding Notes to be redeemed in accordance with a method that complies with the requirements, if any, of any stock exchange on which the Notes are listed, and the applicable procedures of DTC; provided, however, that with respect to any Notes not listed on any stock exchange and/or held through DTC, the Trustee will select such Notes by lot or by such other method that the Trustee considers fair and appropriate.

No Notes of a principal amount of $2,000 or less shall be redeemed in part. Unless the Issuers default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on Notes or portions thereof called for redemption. Additionally, at any time, the Issuers may repurchase Notes in the open market and may hold such Notes or surrender such Notes to the trustee for cancellation.

If any redemption date of any Note is not a business day, then payment of principal and interest may be made on the next succeeding business day with the same force and effect as if made on the nominal redemption date and no interest will accrue for the period after such nominal date.

Payment of Additional Amounts

All payments in respect of the Notes will be made by (or on behalf of) the Issuers free and clear of, and without withholding or deduction for or on account of, any present or future taxes, duties, levies, imposts, assessments or governmental charges of whatever nature (including, without limitation, penalties and interest and other similar liabilities related thereto) (“Taxes”), unless the withholding or deduction of such Taxes is required by law.

In the event that the Issuers are required to withhold or deduct any amount for or on account of any Taxes imposed or levied by or on behalf of Ireland, Luxembourg or any other jurisdiction (other than the United States) in which either of the Issuers is incorporated, resident or doing business for tax purposes or from or through which payments by or on behalf of the Issuers are made, or any political subdivision or any authority thereof or therein (each, but not including the United States or any political subdivision or any authority thereof or therein, a “Relevant Taxing Jurisdiction”), from any payment made under or with respect to any Note (including, without limitation, payments of principal, redemption price, purchase price, interest or premium), the Issuers will pay such additional amounts (“Additional Amounts”) so that the net amount received by each holder or beneficial owner of Notes (including Additional Amounts) after such withholding or deduction will equal the amount that such holder or beneficial owner would have received if such Taxes had not been required to be withheld or deducted.

Additional Amounts will not be payable with respect to a payment made to a holder or beneficial owner of Notes or a holder of beneficial interests in Global Securities where such holder or beneficial owner is subject to taxation on such payment by the Relevant Taxing Jurisdiction for or on account of:

S-21

Additional Amounts also will not be payable for any Taxes that are imposed with respect to any payment on a Note to any holder who is a fiduciary or partnership or person other than the sole beneficial owner of such payment to the extent that no Additional Amounts would have been payable had the beneficial owner of the applicable Note been the holder of such Note.

The Issuers also:

At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable, if the Issuers will be obligated to pay Additional Amounts with respect to such payment, the Issuers will deliver to the Trustee an Officer’s Certificate stating the fact that such Additional Amounts will be payable, the amounts so payable and such other information as is necessary to enable the Trustee to pay such Additional Amounts to holders of such Notes on the payment date (unless such obligation to pay Additional Amounts arises less than 30 days prior to the relevant payment date, in which case the Issuers may deliver such Officer’s Certificate as promptly as practicable after the date that is 30 days prior to the payment date).

S-22

In addition, the Issuers will pay for any present or future stamp, issue, registration, property, excise, transfer, court or documentary or other similar Taxes and duties, including interest, penalties and Additional Amounts with respect thereto, payable in a Relevant Taxing Jurisdiction in respect of the creation, execution, issue, offering, enforcement, redemption or retirement of the Notes or any other document or instrument referred to therein, or the receipt of any payments with respect thereto.

Upon the Issuers’ request, each holder and beneficial owner shall provide a properly completed and executed IRS Form W-9 or IRS Form W-8, as applicable, as would have been applicable if the Issuers were incorporated in the United States of America, any State thereof or the District of Columbia.

The foregoing provisions shall survive any termination or the discharge of the Indenture and shall apply mutatis mutandis to any Successor Company or Successor Co-Issuer.

Whenever in the Indenture, any Notes, or in this “Description of Notes” there is mentioned, in any context, the payment of principal, premium, if any, redemption price, repurchase price, interest or any other amount payable under or with respect to any Notes, such mention shall be deemed to include the payment of Additional Amounts to the extent payable in the particular context.

Offer to Repurchase Upon Change of Control Triggering Event

Upon the occurrence of a Change of Control Triggering Event, unless we have exercised our right to redeem the Notes as described above under “—Optional Redemption,” each holder of the Notes will have the right to require us to purchase all or a portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such holder’s Notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to, but excluding, the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date) (the “Change of Control Payment”). If the Change of Control Payment Date (as defined below) falls on a day that is not a business day, the related payment of the Change of Control Payment will be made on the next business day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next business day.

Within 30 days following the date upon which the Change of Control Triggering Event occurs or, at our option, prior to and conditioned on the occurrence of, any Change of Control, but after the public announcement of the pending Change of Control, we will be required to send, by first class mail, or deliver electronically if the Notes are held by any depositary, a notice to each holder of Notes, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed or delivered electronically (or, in the case of a notice mailed or delivered electronically prior to the date of consummation of a Change of Control, no earlier than the date of the occurrence of the Change of Control), other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed or delivered electronically prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, we will, to the extent lawful:

S-23

We will not be required to make a Change of Control Offer with respect to the Notes if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by us and such third party purchases all the Notes properly tendered and not withdrawn under its offer. In addition, we will not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a Default in the payment of the Change of Control Payment on the Change of Control Payment Date.

We must comply in all material respects with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, we will be required to comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the Indenture with respect to the Notes by virtue of any such conflict.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of JCI plc and its subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the applicability of the requirement that we offer to repurchase the Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of JCI plc and its subsidiaries taken as a whole to another “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) may be uncertain.

Other Provisions of the Notes

Claims against the Issuers for the payment of principal or Additional Amounts, if any, of the Notes will be prescribed ten years after the applicable due date for payment thereof. Claims against the Issuers for the payment of interest, if any, of the Notes will be prescribed five years after the applicable due date for payment of interest.

Certain Covenants

The Indenture contains the following covenants:

Limitation on Liens

JCI plc will not, and will not permit any Restricted Subsidiary to, issue, incur, assume or guarantee any Indebtedness that is secured by a mortgage, pledge, security interest, lien or encumbrance (each a “lien”) upon any asset that at the time of such issuance, assumption or guarantee constitutes a Principal Property, or any shares of, stock of or Indebtedness issued by any Restricted Subsidiary, whether now owned or hereafter acquired, without effectively providing that, for so long as such lien shall continue in existence with respect to such secured Indebtedness, the Notes and any other debt securities issued pursuant to the Base Indenture (together with, if JCI plc shall so determine, any other Indebtedness of JCI plc ranking equally with the Notes and any other debt securities issued pursuant to the Base Indenture, it being understood that for purposes hereof, Indebtedness which is secured by a lien and Indebtedness which is not so secured shall not, solely by reason of such lien, be deemed to be of different ranking) shall be equally and ratably secured by a lien ranking ratably with or equal to (or at JCI plc’s option prior to) such secured Indebtedness; provided, however, that the foregoing covenant shall not apply to:

S-24

S-25

Limitation on Sale and Lease-Back Transactions

JCI plc will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Lease-Back Transaction unless:

Merger and Consolidation

JCI plc will not, directly or indirectly, consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its assets in one or a series of related transactions to, any Person, unless:

(1) the resulting, surviving or transferee Person (the “Successor Company”) will be a corporation, limited liability company, public limited company, limited partnership or other entity organized and existing under the

S-26

laws of (u) the United States of America, any State thereof or the District of Columbia, (v) Ireland, (w) England and Wales, (x) Jersey, (y) any member state of the European Union as in effect on the date the Notes are first issued or (z) Switzerland; provided that the Successor Company (if not the Company) will expressly assume, by a supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company under the Notes and the Indenture;

(2) immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Company or any Restricted Subsidiary as a result of such transaction as having been incurred by the Successor Company or such Restricted Subsidiary at the time of such transaction), no Default shall have occurred and be continuing; and

(3) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with the Indenture.

Notwithstanding the foregoing, (A) any conveyance, transfer or lease of assets between or among the Company and its subsidiaries, including the Co-Issuer, shall not be prohibited under the Indenture and (B) the Company may, directly or indirectly, consolidate with or merge with or into an Affiliate incorporated solely for the purpose of reincorporating the Company in another jurisdiction within the United States of America, any State thereof or the District of Columbia, Ireland, England and Wales, Jersey, any member state of the European Union as in effect on the date the Notes are first issued or Switzerland to realize tax or other benefits.

The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture, and the predecessor issuer, other than in the case of a lease, will be automatically released from all obligations under the Notes and the Indenture, including, without limitation, the obligation to pay the principal of and interest on the Notes.

The Co-Issuer will not, directly or indirectly, consolidate with or merge with or into, or convey, transfer or lease all or substantially all of the Co-Issuer’s assets in one or a series of related transactions to, any Person, unless:

(1) the resulting, surviving or transferee Person (the “Successor Co-Issuer”) will be a corporation, limited liability company, public limited company, limited partnership or other entity organized and existing under the laws of (u) the United States of America, any State thereof or the District of Columbia, (v) Ireland, (w) England and Wales, (x) Jersey, (y) any member state of the European Union as in effect on the date the Notes are first issued or (z) Switzerland; provided that the Successor Co-Issuer (if not the Co-Issuer) will expressly assume, by a supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Co-Issuer under the Notes and the Indenture;

(2) immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Co-Issuer or any Restricted Subsidiary as a result of such transaction as having been incurred by the Successor Co-Issuer or such Restricted Subsidiary at the time of such transaction), no Default shall have occurred and be continuing; and

(3) the Co-Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with the Indenture.

Notwithstanding the foregoing, the Co-Issuer may, directly or indirectly, consolidate with or merge with or into an Affiliate incorporated solely for the purpose of reincorporating the Co-Issuer in another jurisdiction within the United States of America, any State thereof or the District of Columbia, Ireland, England and Wales, Jersey, any member state of the European Union as in effect on the date the Notes are first issued or Switzerland to realize tax or other benefits.

S-27

The Successor Co-Issuer will succeed to, and be substituted for, and may exercise every right and power of, the Co-Issuer under the Indenture, and the predecessor issuer, other than in the case of a lease, will be automatically released from all obligations under the Notes and the Indenture, including, without limitation, the obligation to pay the principal of and interest on the Notes.

Reports by JCI plc

So long as any Notes are outstanding, JCI plc shall file with the Trustee, within 15 days after JCI plc is required to file with the SEC, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may from time to time by rules and regulations prescribe) that JCI plc may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act. JCI plc shall be deemed to have complied with the previous sentence to the extent that such information, documents and reports are filed with the SEC via EDGAR, or any successor electronic delivery procedure; provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to the EDGAR system (or its successor).

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuers’ compliance with any of their covenants under the Indenture (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

The Issuers will furnish to the Trustee on or before 120 days after the end of each fiscal year an Officer’s Certificate stating that in the course of the performance by the signers of their duties as Officers of the Issuers, they would normally have knowledge of any Default by the Issuers in the performance or fulfillment or observance of any covenants or agreements contained in the Indenture during the preceding fiscal year, stating whether or not they have knowledge of any such Default and, if so, specifying each such Default of which the signers have knowledge and the nature thereof.

Listing

We intend to apply to list the New Notes on the New York Stock Exchange. The listing application will be subject to approval by the New York Stock Exchange. If such a listing is obtained, we will have no obligation to maintain such listing, and we may delist the New Notes at any time.

Events of Default

As to the Notes, an “Event of Default” means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1) failure to pay any interest on the Notes when due, which failure continues for 30 days;

(2) failure to pay principal or premium, if any, with respect to the Notes when due;

(3) failure on the part of the Issuers to observe or perform any other covenant, warranty or agreement in the Notes, or in the Indenture as it relates to the Notes, other than a covenant, warranty or agreement, a Default in whose performance or whose breach is specifically dealt with elsewhere in the section of the Indenture governing Events of Default, if the failure continues for 90 days after written notice by the Trustee or the holders of at least 25% in aggregate principal amount of the Notes then outstanding;

(4) an Event of Default with respect to any other series of debt securities issued under the Indenture or an uncured or unwaived failure to pay principal of or interest on any of our other obligations for borrowed money

S-28

beyond any period of grace with respect thereto if, in either case, (a) the aggregate principal amount thereof is in excess of $300,000,000; and (b) the default in payment is not being contested by us in good faith and by appropriate proceedings; and

(5) specified events of bankruptcy, insolvency, receivership or reorganization.

However, the Event of Default in clause (4) above is subject to the following:

Notice and Declaration of Defaults

The Indenture provides that the Trustee will, within the later of 90 days after the occurrence of a Default with respect to any Notes outstanding which is continuing and which is known to a Trust Officer of the Trustee, or 60 days after such Default is actually known to such Trust Officer of the Trustee or written notice of such Default is received by the Trustee, give to the holders of the Notes notice, by mail as the names and addresses of such holders appear on the security register, or electronically if the Notes are held by any depositary, of all uncured Defaults known to it, including events specified above without grace periods, unless such Defaults shall have been cured before the giving of such notice; provided that, except in the case of Default in the payment of the principal of, premium, if any, or interest on any of the Notes, the Trustee shall be protected in withholding such notice to the holders if the Trustee in good faith determines that withholding of such notice is in the interests of the holders of the Notes.

The Trustee or the holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the Notes immediately due and payable upon the occurrence of any Event of Default. The holders of a majority in principal amount of the outstanding debt securities of all series issued under the Base Indenture affected by such waiver (voting as one class), on behalf of the holders of all of the debt securities of all such series, may waive any existing Default and its consequences, except a Default in the payment of principal, premium, if any, or interest, including sinking fund payments (provided, however, that only holders of a majority in aggregate principal amount of the debt securities of an applicable series may rescind an acceleration with respect to such series and its consequences, including any related payment default that resulted from such acceleration).

Actions upon Default

In case an Event of Default with respect to the Notes occurs and is continuing, the Indenture provides that the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the holders of Notes unless the applicable holders have offered to the Trustee security and indemnity, satisfactory to the Trustee in its sole discretion, against any loss, liability or expense which may

S-29

be incurred thereby. The right of a holder of any Note to institute a proceeding with respect to the Notes is subject to conditions precedent including notice and indemnity to the Trustee, but the right of any holder of any Note to receive payment of the principal of, and premium, if any, and interest on their due dates or to institute suit for the enforcement thereof shall not be impaired or affected without the consent of such holder.

The holders of a majority in aggregate principal amount of the Notes outstanding will have the right to direct the time, method and place for conducting any proceeding for any remedy available to the Trustee or exercising any power or trust conferred on the Trustee. Any direction by such holders will be in accordance with law and the provisions of the Indenture. Subject to certain provisions of the Indenture, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith, by a Trust Officer or Trust Officers of the Trustee, shall determine that the action or proceeding so directed may not be lawfully taken, would involve the Trustee in personal liability, would be materially or unjustly prejudicial to the rights of holders of Notes not joining in such direction or would be unduly prejudicial to the interests of the holders of the debt securities issued under the Base Indenture of all series not joining in the giving of such direction. The Trustee will be under no obligation to act in accordance with any such direction unless the applicable holders offer the Trustee reasonable security and indemnity, satisfactory to the Trustee in its sole discretion, against costs, expenses and liabilities which may be incurred thereby.

Modification of the Indenture

The Issuers and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental to the Indenture, which shall conform to the provisions of the Trust Indenture Act as then in effect, without the consent of the holders of the Notes, for one or more of the following purposes:

In addition, under the Indenture, with the consent (evidenced as provided in the Indenture) of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of all series affected by such supplemental indenture or indentures (voting as one class), the Issuers and the Trustee from time to time and at any time may enter into an indenture or indentures supplemental to the Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture thereto or of modifying in any manner not covered by the immediately preceding paragraph the rights of the holders of the debt securities of each such series under the Indenture. However, the following changes may only be made with the consent of each holder of outstanding Notes affected:

A supplemental indenture that changes or eliminates any covenant, event of default set forth in the Base Indenture or other provision of the Indenture that has been expressly included solely for the benefit of one or more particular series of debt securities, if any, or which modifies the rights of the holders of debt securities of such series with respect to such covenant, event of default or other provision, shall be deemed not to affect the rights under the Indenture of the holders of debt securities of any other series.

Notwithstanding anything herein or otherwise, the provisions under the Indenture relative to the Issuers’ obligation to make any offer to repurchase the Notes as a result of a Change of Control Triggering Event as provided in Section 4.08 of the Base Indenture may be waived or modified with the written consent of the holders of a majority in principal amount of the outstanding debt securities of the applicable series or multiple affected series.

S-31

It will not be necessary for the consent of the holders of the Notes to approve the particular form of any proposed supplement, amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

Information Concerning the Trustee

If an Event of Default with respect to the Notes has occurred and is continuing, the Trustee shall exercise with respect to the Notes such of the rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise, as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs. If an Event of Default has occurred and is continuing, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any holders of Notes, unless such holders shall have offered to the Trustee security and indemnity, satisfactory to it in its sole discretion, against any loss, liability or expense which may be incurred thereby, and then only to the extent required by the terms of the Indenture. No provision of the Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties under the Indenture or in the exercise of any of its rights or powers.

The Trustee may resign with respect to the Notes by giving a written notice to the Issuers. The holders of a majority in principal amount of the outstanding Notes may remove the Trustee with respect to the Notes by notifying the Issuers and the Trustee in writing. The Issuers may remove the Trustee if:

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee with respect to the Notes for any reason, the Issuers shall promptly appoint a successor Trustee with respect to the Notes.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of the appointment as provided in the Indenture.

The Trustee and its Affiliates have engaged, currently are engaged, and may in the future engage in financial or other transactions with the Issuers and our Affiliates in the ordinary course of their respective businesses.

Payment and Paying Agents

The Issuers will pay the principal of, premium, if any, and interest on the Notes at any office of ours or any agency designated by us.

The initial paying agent for the Notes will be the Trustee. In addition, the Issuers will maintain a transfer agent and a security registrar for the Notes. The initial transfer agent and security registrar will be the Trustee. The Trustee’s registered address is 1555 North RiverCenter Drive, Suite 203, Milwaukee, WI 53212.

The security registrar as to the Notes will maintain a register reflecting ownership of the Notes outstanding from time to time, if any, and together with the applicable transfer agent, will make payments on and facilitate transfers of the Notes on behalf of the Issuers. No service charge will be made for any registration of transfer or exchange of Notes. However, we may require holders to pay any transfer taxes or other similar governmental charges payable in connection with any such transfer or exchange.

S-32

The Issuers may change or appoint any paying agent, security registrar or transfer agent with respect to the Notes without prior notice to the holders of the Notes. The Issuers or any of their subsidiaries may act as paying agent, transfer agent or security registrar in respect of any Notes.

Governing Law

The Indenture and any Notes issued thereunder shall be deemed to be a contract made under the internal laws of the State of New York, and for all purposes shall be construed in accordance with the laws of the State of

New York without regard to conflicts of laws principles that would require the application of any other law. The Indenture is subject to the provisions of the Trust Indenture Act that are required to be part of the Indenture and shall, to the extent applicable, be governed by such provisions.

For the avoidance of doubt, articles 470-1 to 470-19 of the Luxembourg law of 10 August 1915 relating to commercial companies, as amended, do not apply to the Notes.

Satisfaction and Discharge of the Indenture

The Indenture shall cease to be of further effect with respect to the Notes if, at any time:

(a) The Issuers have delivered or have caused to be delivered to the Trustee for cancellation all Notes theretofore authenticated, other than any Notes that have been destroyed, lost or stolen and that have been replaced or paid as provided in the Indenture, and Notes for whose payment funds or Governmental Obligations have theretofore been deposited in trust or segregated and held in trust by the Issuers and thereupon repaid to the Issuers or discharged from such trust, as provided in the Indenture; or

(b) all such Notes not theretofore delivered to the Trustee for cancellation have become due and payable or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and the Issuers shall irrevocably deposit or cause to be deposited with the Trustee as trust funds the entire amount, in funds or Governmental Obligations, or a combination thereof, sufficient to pay at maturity or upon redemption all Notes not theretofore delivered to the Trustee for cancellation, including principal, premium, if any, and interest due or to become due on such date of maturity or redemption date, as the case may be, and if in either case the Issuers shall also pay or cause to be paid all other sums payable under the Indenture with respect to such Notes by the Issuers.

With respect to any redemption of any Notes that requires the payment of any premium, the amount deposited pursuant to the above paragraph shall be sufficient for purposes of the Indenture to the extent that an amount is so deposited with the Trustee or paying agent, as applicable, equal to such premium on such Notes calculated as of the date of the notice of redemption, with any deficit on the redemption date only required to be deposited with the Trustee or paying agent, as applicable, on or prior to the redemption date.

Notwithstanding the above, the Issuers may not be discharged from the following obligations, which will survive until the date of maturity or the redemption date, as the case may be, for the Notes:

S-33

The Issuers also may not be discharged from the following obligations, which will survive the defeasance and discharge of the Notes:

Defeasance and Discharge of Obligations

The Issuers’ obligations with respect to the Notes will be discharged upon compliance with the conditions under the caption “Covenant Defeasance”; provided that the Issuers may not be discharged from the following obligations, which will survive until such date of maturity or the redemption date, as the case may be, for the Notes:

The Issuers also may not be discharged from the following obligations, which will survive the satisfaction and discharge of the Notes:

Covenant Defeasance

Upon compliance with specified conditions, the Issuers may, at their option and at any time, by written notice executed by an Officer delivered to the Trustee, elect to have their obligations, to the extent applicable, under the covenants described under “—Offer to Repurchase Upon Change of Control Triggering Event” and “—Certain Covenants” above, and the operation of the Event of Default described in clause (3) of the first paragraph under the caption “—Events of Default” above, discharged with respect to all outstanding Notes and the Indenture insofar as such Notes are concerned. For this purpose, such covenant defeasance means that, with respect to the outstanding Notes, the Issuers may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference in the Indenture to any such covenant or by reason of reference in any such covenant to any other provision of the Indenture or in any other document and such omission to comply shall not constitute a Default or an Event of Default relating to the Notes. These conditions are:

S-34

The term “net rental payments” under any lease of any period shall mean the sum of the rental and other payments required to be paid in such period by the lessee thereunder, not including any amounts required to be paid by such lessee, whether or not designated as rental or additional rental, on account of maintenance and repairs, reconstruction, insurance, taxes, assessments, water rates or similar charges required to be paid by such lessee thereunder or any amounts required to be paid by such lessee thereunder contingent upon the amount of sales, maintenance and repairs, reconstruction, insurance, taxes, assessments, water rates or similar charges.

“Change of Control” means the occurrence of any of the following after the date of issuance of the Notes:

(1) the direct or indirect sale, lease, 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 Company’s assets and the assets of its subsidiaries taken as a whole to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries, other than any such transaction or series of related transactions where holders of our Voting Stock outstanding immediately prior thereto hold Voting Stock of the transferee Person representing a majority of the voting power of the transferee Person’s Voting Stock immediately after giving effect thereto;

(2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than us or one of our subsidiaries) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of the Company’s Voting Stock representing a majority of the voting power of the Company’s outstanding Voting Stock;

“Change of Control Triggering Event” means, the Notes cease to be rated Investment Grade by each of the Rating Agencies on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement by us of any Change of Control (or pending Change of Control) and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended following consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings downgrade or withdrawal). However, a Change of Control Triggering Event otherwise arising by virtue of a particular reduction in, or withdrawal of, rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Change of Control Triggering Event for purposes of the definition of Change of Control Triggering Event) if the Rating Agencies making the reduction in, or withdrawal of, rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at our request that the reduction or withdrawal was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Change of Control Triggering Event). If a Rating Agency is not providing a rating for the Notes at the commencement of any Trigger Period, the Notes will be deemed to have ceased to be rated Investment Grade by such Rating Agency during that Trigger Period.

S-36

Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

BOOK-ENTRY, DELIVERY AND FORM

We have obtained the information in this section concerning DTC, Clearstream and Euroclear and their book-entry systems and procedures from sources that we believe to be reliable. We take no responsibility for an accurate portrayal of this information. In addition, the description of the clearing systems in this section reflects our understanding of the rules and procedures of DTC, Clearstream and Euroclear as they are currently in effect. The clearing systems may change their rules and procedures at any time without notice.

The New Notes will initially be represented by one or more fully registered global notes (“Global Securities”). The Global Securities will be deposited with or on behalf of The Depository Trust Company, which we refer to as DTC, and registered in the name of Cede & Co., as nominee of DTC or such other name as may be requested by an authorized representative of DTC.

Beneficial interests in the New Notes will be shown on, and transfers thereof will be effected only through, records maintained by DTC and its direct and indirect participants, including Euroclear Bank SA/NV, as operator of the Euroclear System (“Euroclear”) and Clearstream Banking, société anonyme, Luxembourg (“Clearstream Banking”). Investors may elect to hold interests in the New Notes through any of DTC, Euroclear or Clearstream Banking, if they are participants in these systems, or indirectly through organizations which are participants in these systems. Euroclear and Clearstream Banking hold securities on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries, which in turn hold the securities in customers’ securities accounts in the depositaries’ names on the books of DTC.

DTC has informed us that DTC is:

Euroclear and Clearstream Banking have informed us that: Euroclear and Clearstream Banking each hold securities for their customers and facilitate the clearance and settlement of securities transactions by electronic book-entry transfer between their respective account holders. Euroclear and Clearstream Banking provide various services including safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Euroclear and Clearstream Banking also deal with domestic securities markets in several countries through established depositary and custodial relationships. Euroclear and Clearstream Banking have established an electronic bridge between their two systems across which their respective participants may settle trades with each other.

Euroclear and Clearstream Banking customers are world-wide financial institutions including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations. Indirect access to Euroclear and Clearstream Banking is available to other institutions, which clear through or maintain a custodial relationship with an account holder of either system.

DTC holds securities that its participants (“Direct Participants”) deposit with DTC. DTC also facilitates the settlement among Direct Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Direct Participants’ accounts, which eliminates the need for physical movement of securities certificates. Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC,

S-40

National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as securities brokers and dealers, banks, and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The rules applicable to DTC and its Direct and Indirect Participants are on file with the SEC.

Purchases of New Notes under the DTC system must be made by or through Direct Participants, which receive a credit for the New Notes on DTC’s records. The ownership interest of each actual purchaser of each Note (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmations from DTC of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the New Notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the New Notes except in the event that use of the book-entry system for the New Notes is discontinued. As a result, the ability of a person having a beneficial interest in the New Notes to pledge such interest to persons or entities that do not participate in the DTC system, or to otherwise take actions with respect to such interest, may be affected by the lack of a physical certificate evidencing such interest. In addition, the laws of some states require that certain persons take physical delivery in definitive form of securities that they own and that security interests in negotiable instruments can only be perfected by delivery of certificates representing the instruments. Consequently, the ability to transfer New Notes evidenced by the Global Securities will be limited to such extent.

To facilitate subsequent transfers, all New Notes deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of New Notes with DTC and their registration in the name of Cede & Co. or such other nominee do not affect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the New Notes; DTC’s records reflect only the identity of the Direct Participants to whose accounts such New Notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Beneficial Owners of New Notes may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the New Notes, such as redemptions, tenders, defaults, and proposed amendments to the documents related to the Notes. For example, Beneficial Owners of Notes may wish to ascertain that the nominee holding the New Notes for their benefit has agreed to obtain and transmit notices to Beneficial Owners. In the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of notices be provided directly to them. Redemption notices will be sent to DTC. If less than all of the New Notes are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the New Notes. Under its usual procedures, DTC mails an Omnibus Proxy to the issuer as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts the New Notes are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Payments of principal, interest and premium, if any, on the New Notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct

S-41

Participants’ accounts, upon DTC’s receipt of funds and corresponding detail information from us on the payable date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name” and will be the responsibility of such Participant and not of DTC, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is our responsibility and disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

Investors electing to hold their New Notes through DTC will follow the settlement practices applicable to U.S. corporate debt obligations. The securities custody accounts of investors will be credited with their holdings on the settlement date against payment in same-day funds within DTC effected in U.S. dollars.

Investors electing to hold their New Notes through Euroclear or Clearstream Banking accounts will follow the settlement procedures applicable to conventional eurobonds.

Secondary market sales of book-entry interests in the New Notes between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled using the procedures applicable to United States corporate debt obligations in DTC’s Settlement System. Secondary market sales of book-entry interests in the New Notes held through Euroclear or Clearstream Banking to purchasers of book-entry interests in the New Notes through Euroclear or Clearstream Banking will be conducted in accordance with the normal rules and operating procedures of Euroclear and Clearstream Banking and will be settled using the procedures applicable to conventional eurobonds.

DTC may discontinue providing its services as securities depositary with respect to the New Notes at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor securities depositary is not obtained, note certificates are required to be printed and delivered. In addition, we may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depositary). In that event, we will issue New Notes in registered definitive form in exchange for the Global Securities representing such New Notes. We will not have any responsibility or obligation to participants in the DTC system or the persons for whom they act as nominees with respect to the accuracy of the records of DTC, its nominee or any Direct or Indirect Participant with respect to any ownership interest in the New Notes, or with respect to payments to or providing of notice for the Direct Participants, the Indirect Participants or the beneficial owners of the New Notes.

The information in this section concerning DTC, Euroclear, Clearstream Banking and their book-entry systems has been obtained from sources that we believe to be reliable. Neither we, the trustee nor the underwriters, dealers or agents are responsible for the accuracy or completeness of this information.

CERTAIN IRELAND TAX CONSIDERATIONS

Ireland

The following is a summary based on the laws and practices currently in force in Ireland of certain matters regarding the tax position of investors who are the absolute beneficial owners of their New Notes and who are not associated with the Issuers (otherwise then by virtue of holding the Notes). It should be treated with appropriate caution. Particular rules not discussed may apply to certain classes of taxpayers holding New Notes including dealers in securities and trusts. The summary does not constitute tax or legal advice and the comments below are of a general nature only. Investors should consult their professional advisers on the tax implications of the purchase, holding, redemption or sale of the New Notes and the receipt of interest thereon under the laws of their country of residence, citizenship or domicile.

Withholding Tax

Payments of accrued discount should not be subject to any withholding or deduction for or on account of Irish income tax.

In general, tax at the standard rate of income tax (currently 20%) is required to be withheld from payments of Irish source interest which should include interest payable on the New Notes by the Company. The Company will not be obliged to make a withholding or deduction for or on account of Irish income tax from a payment of interest on a New Note where:

Thus, so long as the New Notes continue to be quoted on the New York Stock Exchange and are held in a clearing system recognised by the Irish Revenue Commissioners (Euroclear, Clearstream and DTC, amongst others, so recognised), interest on the New Notes can be paid by any paying agent acting on behalf of the Issuers free of any withholding or deduction for or on account of Irish income tax.

If the New Notes continue to be quoted on the New York Stock Exchange but cease to be held in a recognised clearing system, interest on the New Notes may be paid without any withholding or deduction for or on account of Irish income tax provided such payment is made through a paying agent outside Ireland.

Encashment Tax

In certain circumstances, Irish tax will be required to be withheld at a rate of 25% from interest on any New Note, where such interest is collected or realized by a bank or encashment agent in Ireland on behalf of any holder of a New Note. There is an exemption from encashment tax where (i) the beneficial owner of the interest is not resident in Ireland and has made a declaration to this effect in the prescribed form to the encashment agent or bank or (ii) the beneficial owner of the interest is a company which is within the charge to Irish corporation tax in respect of the interest.

S-43

Stamp Duty

No Irish stamp duty or similar tax is imposed in Ireland on the issue of the New Notes.

The transfer of interests in the New Notes may, in certain circumstances, result in a charge to Irish stamp duty. However, a transfer of the New Notes in bearer form by physical delivery only (and not otherwise) should not give rise to a charge to Irish stamp duty.

No stamp duty will arise on any transfer or redemption of the New Notes (on the basis of an exemption provided for in Section 85(2) of the Stamp Duties Consolidation Act, 1999) where the New Notes satisfy the following four conditions. The New Notes:

CERTAIN LUXEMBOURG TAX CONSIDERATIONS

The following information is of a general nature only and is based on the laws presently in force in Luxembourg, though it is not intended to be, nor should it be construed to be, legal or tax advice. Investors in the New Notes should therefore consult their own professional advisers as to the effects of state, local or foreign laws, including Luxembourg tax law, to which they may be subject.

Please be aware that the residence concept used under the respective headings below applies for Luxembourg income tax assessment purposes only. Any reference in the present section to a tax, duty, levy, impost or other charge or withholding of a similar nature, or to any other concepts, refers to Luxembourg tax law and/or concepts only. Also, please note that a reference to Luxembourg income tax encompasses corporate income tax (impôt sur le revenu des collectivités), municipal business tax (impôt commercial communal), a solidarity surcharge (contribution au fonds pour l’emploi) as well as personal income tax (impôt sur le revenu) generally. Investors may further be subject to net wealth tax (impôt sur la fortune) as well as other duties, levies or taxes. Corporate income taxes, municipal business tax, net wealth tax, as well as the solidarity surcharge invariably apply to most corporate taxpayers resident in Luxembourg for tax purposes. Individual taxpayers are generally subject to personal income tax and the solidarity surcharge. Under certain circumstances, where an individual taxpayer acts in the course of the management of a professional or business undertaking, municipal business tax may apply as well.

Withholding Tax

Non-resident holders of New Notes

Under Luxembourg general tax laws currently in force, there is no withholding tax on payments of principal, premium or interest made to non-resident holders of New Notes, nor on accrued but unpaid interest in respect of the New Notes, nor is any Luxembourg withholding tax payable upon redemption or repurchase of the New Notes held by non-resident holders of New Notes.

Resident holders of New Notes

Under Luxembourg general tax laws currently in force and subject to the law of 23 December 2005, as amended (the “Relibi Law”), there is no withholding tax on payments of principal, premium or interest made to Luxembourg resident holders of New Notes, nor on accrued but unpaid interest in respect of New Notes, nor is any Luxembourg withholding tax payable upon redemption or repurchase of New Notes held by Luxembourg resident holders of New Notes.

Under the Relibi Law, payments of interest or similar income made or ascribed by a paying agent established in Luxembourg to an individual beneficial owner who is a resident of Luxembourg will be subject to a withholding tax of 20%. Such withholding tax will be in full discharge of income tax if the beneficial owner is an individual acting in the course of the management of his/her private wealth. Responsibility for the withholding of the tax will be assumed by the Luxembourg paying agent. Payment of interest under the New Notes coming within the scope of the Relibi Law will be subject to a withholding tax at a rate of 20%.

Income Taxation

Holders of the New Notes—Luxembourg tax residency

Holders of New Notes will not be deemed to be resident, domiciled or carrying on business in Luxembourg solely by reason of holding, execution, performance, delivery, exchange and/or enforcement of the New Notes.

Non-resident holders of New Notes

A non-resident holder of New Notes, not having a permanent establishment or permanent representative in Luxembourg to which/whom such New Notes are attributable, is not subject to Luxembourg income tax on

S-45

interest accrued or received, redemption premiums or issue discounts, under the New Notes. A gain realised by such non-resident holder of New Notes on the sale or disposal, in any form whatsoever, of the New Notes is further not subject to Luxembourg income tax.

A non-resident corporate holder of New Notes or an individual holder of New Notes acting in the course of the management of a professional or business undertaking, who has a permanent establishment or permanent representative in Luxembourg to which or to whom such New Notes are attributable, is subject to Luxembourg income tax on interest accrued or received, redemption premiums or issue discounts, under the New Notes and on any gains realised upon the sale or disposal, in any form whatsoever, of the New Notes.

Resident holders of New Notes

Holders of New Notes who are residents of Luxembourg will not be liable for any Luxembourg income tax on repayment of principal.

(i) Luxembourg resident corporate holder of New Notes

A corporate holder of New Notes must include any interest accrued or received, any redemption premium or issue discount, as well as any gain realised on the sale or disposal, in any form whatsoever, of the New Notes, in its taxable income for Luxembourg income tax assessment purposes.

A corporate holder of New Notes that is governed by the law of 11 May 2007 on family estate management companies, as amended, or by the law of 17 December 2010 on undertakings for collective investment, as amended, by the law of 13 February 2007 on specialised investment funds, as amended, or by the law of 23 July 2016 on reserved alternative investment funds, as amended, and which does not fall under the special tax regime set out in article 48 thereof is neither subject to Luxembourg income tax in respect of interest accrued or received, any redemption premium or issue discount, nor on gains realised on the sale or disposal, in any form whatsoever, of the New Notes.

(ii) Luxembourg resident individual holder of New Notes

An individual holder of New Notes, acting in the course of the management of his/her private wealth, is subject to Luxembourg income tax at progressive rates in respect of interest received, redemption premiums or issue discounts, under the New Notes, except if:

A gain realised by an individual holder of New Notes, acting in the course of the management of his/her private wealth, upon the sale or disposal, in any form whatsoever, of New Notes is not subject to Luxembourg income tax, provided this sale or disposal took place more than six months after the New Notes were acquired. However, any portion of such gain corresponding to accrued but unpaid interest income is subject to Luxembourg income tax, except if tax has been levied on such interest in accordance with the Relibi Law.

An individual holder of New Notes acting in the course of the management of a professional or business undertaking must include this interest in its taxable basis. If applicable, the tax levied in accordance with the Relibi Law will be credited against his/her final tax liability.

S-46

Net Wealth Taxation

A corporate holder of New Notes, whether it is a resident of Luxembourg for tax purposes or, if not, it maintains a permanent establishment or a permanent representative in Luxembourg to which/whom such New Notes are attributable, is subject to Luxembourg wealth tax on such New Notes, except if the holder of New Notes is governed by:

Please however note that securitisation companies governed by the law of 22 March 2004 on securitisation, as amended, or capital companies governed by the law of 15 June 2004 on venture capital vehicles, as amended, or reserved alternative investment funds governed by the law of 23 July 2016 and which fall under the special tax regime set out under article 48 thereof may, under certain conditions, be subject to minimum net wealth tax.

An individual holder of New Notes, whether he/she is a resident of Luxembourg or not, is not subject to Luxembourg wealth tax on such New Notes.

Other Taxes

In principle, neither the issuance nor the transfer, repurchase or redemption of New Notes will give rise to any Luxembourg registration tax or similar taxes.

However, a fixed or ad valorem registration duty may be due upon the registration of the New Notes in Luxembourg in the case where the New Notes are physically attached to a public deed or to any other document subject to mandatory registration, as well as in the case of a registration of the New Notes on a voluntary basis.

Where a holder of New Notes is a resident of Luxembourg for tax purposes at the time of his/her death, the New Notes are included in his/her taxable estate for inheritance tax assessment purposes.

Gift tax may be due on a gift or donation of New Notes if embodied in a Luxembourg deed passed in front of a Luxembourg notary or recorded in Luxembourg.

S-47

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax consequences of the purchase, ownership and disposition of the New Notes. This summary deals only with New Notes that are held as capital assets (generally, property held for investment) by a U.S. Holder (as defined below) who acquires the New Notes pursuant to this offering at their initial offering price. A “U.S. Holder” means a beneficial owner of the New Notes that is, for U.S. federal income tax purposes, any of the following:

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those summarized below. This summary does not address all of the U.S. federal income tax consequences that may be relevant to U.S. Holders in light of their personal circumstances, nor does it address the Medicare contribution tax on net investment income, U.S. federal estate and gift taxes or any state, local, non-U.S. or other tax considerations that may be relevant to U.S. Holders in light of their particular circumstances. In addition, it does not represent a detailed description of the U.S. federal income tax consequences applicable to you if you are subject to special treatment under the U.S. federal income tax laws. For example, this summary does not address:

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the New Notes, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner of a partnership holding the New Notes, you should consult your tax advisors.

If you are considering the purchase of New Notes, you should consult your own tax advisors concerning the particular U.S. federal income tax consequences to you of the purchase, ownership and disposition of the New Notes, as well as the consequences to you arising under other U.S. federal tax laws and the laws of any other taxing jurisdiction.

S-48

Qualified Reopening

We intend to treat the issuance of the New Notes offered hereby as constituting a “qualified reopening” of the Initial Notes for U.S. federal income tax purposes. In such case, the New Notes offered hereby will be deemed to have the same issue date and issue price as the Initial Notes, and will be fungible with the Initial Notes for U.S. federal income tax purposes. The remainder of this discussion assumes that the issuance of the New Notes offered hereby will be treated as a qualified reopening of the Initial Notes for U.S. federal income tax purposes.

Pre-Issuance Accrued Interest

The initial offering price for the New Notes will include amounts attributable to unpaid interest accrued from December 1, 2024 through the closing date of this offering, which we call “pre-issuance accrued interest.” For U.S. federal income tax purposes, we intend to take the position (to the extent we are required to take a position) that the New Notes offered hereby are purchased for a price that does not include any pre-issuance accrued interest. Accordingly, the portion of the first interest payment equal to the pre-issuance accrued interest should be treated as a nontaxable return of such pre-issuance accrued interest and should not be taxable as interest on the New Notes.

Payments of Interest

Interest on a New Note (including any non-U.S. tax withheld and additional amounts paid in respect thereof but excluding any pre-issuance accrued interest excluded from the purchase price of the New Notes, as discussed above under “—Pre-Issuance Accrued Interest”) will generally be taxable to you as ordinary income at the time it is paid or accrued in accordance with your method of accounting for U.S. federal income tax purposes.

Subject to certain conditions and limitations (including a minimum holding period requirement) and the Foreign Tax Credit Regulations (as defined below), any non-U.S. withholding taxes on interest may be treated as foreign taxes eligible for credit against your U.S. federal income tax liability. For purposes of calculating the U.S. foreign tax credit, interest (including any additional amounts) on a New Note will be treated as income from sources outside the United States and will generally constitute passive category income. However, certain United States Treasury regulations addressing foreign tax credits (the “Foreign Tax Credit Regulations”) impose additional requirements for foreign taxes to be eligible for a foreign tax credit if the relevant taxpayer does not elect to apply the benefits of an applicable income tax treaty, and there can be no assurance that those requirements will be satisfied. The Department of the Treasury and the Internal Revenue Service (the “IRS”) are considering proposing amendments to the Foreign Tax Credit Regulations. In addition, recent notices from the IRS provide temporary relief by allowing taxpayers that comply with applicable requirements to apply many aspects of the foreign tax credit regulations as they previously existed (before the release of the current Foreign Tax Credit Regulations) for taxable years ending before the date that a notice or other guidance withdrawing or modifying the temporary relief is issued (or any later date specified in such notice or other guidance). Instead of claiming a foreign tax credit, you may be able to deduct any non-U.S. withholding taxes on interest in computing your taxable income, subject to generally applicable limitations under U.S. law (including that a U.S. Holder is not eligible for a deduction for otherwise creditable foreign income taxes paid or accrued in a taxable year if such U.S. Holder claims a foreign tax credit for any foreign income taxes paid or accrued in the same taxable year). The rules governing the foreign tax credit and deductions for foreign taxes are complex. You are urged to consult your tax advisors regarding the Foreign Tax Credit Regulations (and the related temporary relief in the IRS notices) and the availability of the foreign tax credit or a deduction under your particular circumstances.

Sale, Exchange, Retirement, Redemption or other Taxable Disposition of New Notes

Upon the sale, exchange, retirement, redemption or other taxable disposition of a New Note, you will recognize gain or loss equal to the difference, if any, between the amount you receive for the New Note in cash or other property valued at fair market value on the date of such disposition (less an amount equal to any accrued

S-49

but unpaid interest (including pre-issuance accrued interest), which will be treated in the manner described above) and your adjusted tax basis in the New Note. Your adjusted tax basis in a New Note will generally be your cost for that New Note (excluding any amount attributable to pre-issuance accrued interest excluded from the purchase price of a New Note, as discussed above under “—Pre-Issuance Accrued Interest”).

Any gain or loss you recognize will generally be capital gain or loss and will generally be long-term capital gain or loss if you have held the New Note for more than one year. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains of non-corporate U.S. Holders (including individuals) are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss you recognize will generally be treated as U.S. source gain or loss.

Backup Withholding and Information Reporting

Generally, information reporting will apply to all payments of interest and principal on a New Note and the proceeds from a sale or other disposition of a New Note that are paid to you within the United States (and in certain cases, outside the United States), unless you establish that you are an exempt recipient such as a corporation. Additionally, if you fail to provide your taxpayer identification number, or, in the case of interest payments, fail either to report in full dividend and interest income or to make certain certifications, you may be subject to backup withholding on any such payments or proceeds.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is timely furnished to the IRS.

UNDERWRITING

BofA Securities, Inc. and U.S. Bancorp Investments Inc. are acting as joint book-running managers of the offering and as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally, and not jointly, agreed to purchase, and we have agreed to sell to that underwriter, the principal amount of notes set forth opposite the underwriter’s name.

The underwriters have agreed, severally and not jointly, to take and pay for all of the New Notes being offered, if any are taken. The offering of the New Notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part. The underwriting agreement provides that the obligations of the several underwriters to pay and accept for delivery of the New Notes offered by this prospectus supplement are subject to approval of legal matters by counsel and to certain other conditions.

New Notes sold by the underwriters to the public will initially be offered at the price set forth on the cover of this prospectus supplement. Any New Notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price of up to 0.400% of the principal amount of the New Notes. If all the New Notes are not sold at the price set forth on the cover of this prospectus supplement, the underwriters may change the offering price and the other selling terms.

The following table shows the underwriting discount that we are to pay to the underwriters in connection with this offering:

We estimate that our share of the total expenses of the offering, excluding the underwriting discount, will be approximately $0.9 million. We have also agreed to reimburse the underwriters for certain of their expenses in connection with any filings required to be made with Financial Industry Regulatory Authority (FINRA) relating to the New Notes in an amount of up to $25,000.

We expect that delivery of the New Notes will be made against payment therefor on or about the closing date of this offering specified on the cover page, which is three business days following the date of pricing of the New Notes (this settlement cycle being referred to as “T+3”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade New Notes prior to the business day before the delivery of the New Notes hereunder will be required, by virtue of the fact that the New Notes initially will settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the New Notes who wish to trade the New Notes prior to their date of delivery hereunder should consult their advisors.

S-51

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or under certain circumstances to contribute to payments which the underwriters may be required to make in that respect.

We intend to apply to list the New Notes on the New York Stock Exchange. We expect trading in the New Notes on the New York Stock Exchange to begin within 30 days after the issue date of the New Notes. If such a listing is obtained, we will have no obligation to maintain such listing, and we may delist the Notes at any time. The New Notes are a new issue of securities with no established trading market. We have been advised by the underwriters that the underwriters intend to make a market in the Notes but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the Notes.

In connection with the offering, the underwriters may purchase and sell New Notes in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions and stabilizing purchases.

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the New Notes. They may also cause the price of the New Notes to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise.

To the extent any underwriter that is not a U.S.-registered broker-dealer intends to effect sales of the New Notes in the United States, it will do so through one or more U.S.-registered broker-dealers in accordance with the applicable U.S. securities laws and regulations.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities. The underwriters and their respective affiliates have from time to time provided, and may provide in the future, various financial advisory, investment banking and commercial banking services to us and our affiliates, for which they have received or will receive customary fees and reimbursement of expenses. In particular, certain of the underwriters or their affiliates act as lenders and/or as agents under JCI plc’s or JCI plc’s subsidiaries’ credit facilities and commercial paper program, for which they receive and may continue to receive customary fees and expenses. In addition, U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the trustee.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (which may include bank loans, commercial paper and/or credit default swaps) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain

S-52

other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the New Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the New Notes. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Selling Restrictions

The New Notes are being offered for sale in the United States and may be offered for sale in jurisdictions outside the United States, subject to applicable law.

European Economic Area

The New Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes,

(A) a “retail investor” means a person who is one (or more) of the following:

(i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or

(ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or

(iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”), and

(B) the expression an “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the New Notes to be offered so as to enable an investor to decide to purchase or subscribe for the New Notes.

Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the New Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the New Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of New Notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of New Notes. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the Prospectus Regulation or the Luxembourg law dated 16 July 2019 on prospectuses for securities (Loi relative aux prospectus pour valeurs mobilières).

United Kingdom

The New Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (“UK”). For these purposes,

(A) a retail investor means a person who is one (or more) of the following:

(i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law in the UK by virtue of the European Union (Withdrawal) Act 2018 (“EUWA”); or

S-53

(ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, “FSMA”) and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law in the UK by virtue of the EUWA; or

(iii) not a qualified investor as defined in Article 2 of the Prospectus Regulation as it forms part of domestic law in the UK by virtue of the EUWA (the “UK Prospectus Regulation”); and

(B) the expression an “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the New Notes to be offered so as to enable an investor to decide to purchase or subscribe for the New Notes.

Consequently, no key information document required by the PRIIPs Regulation as it forms part of domestic law in the UK by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the New Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the New Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of New Notes in the UK will be made pursuant to an exemption under the FSMA and the UK Prospectus Regulation from the requirement to publish a prospectus for offers of notes. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the UK Prospectus Regulation.

In the UK, this prospectus supplement is being distributed only to, and is directed only at, persons who are “qualified investors” (as defined in the UK Prospectus Regulation) who are (i) persons having professional experience in matters relating to investments and who qualify as investment professionals within the meaning of Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the “Order”), (ii) persons falling within Article 49(2)(a) to (d) of the Order, or (iii) (“high net worth companies, unincorporated associations etc.”) persons to whom it would otherwise be lawful to distribute it, all such persons together being referred to as “Relevant Persons.” In the UK, the New Notes are only available to, and any invitation, offer or agreement to subscribe, purchase or otherwise acquire such New Notes will be engaged in only with, Relevant Persons. This prospectus supplement and its contents are confidential and should not be distributed, published or reproduced (in whole or in part) or disclosed by any recipients to any other person in the UK. Any person in the UK that is not a Relevant Person should not act or rely on this prospectus supplement or its contents. The New Notes are not being offered to the public in the UK.

Ireland

No action may be taken with respect to the New Notes in or involving Ireland otherwise than in conformity with the provisions of (a) the European Union (Markets in Financial Instruments) Regulations 2017 (S.I. No. 375 of 2017) (as amended) of Ireland (the “MiFID Regulations”), including, without limitation, Regulation 5 (Regulation for authorisation (and certain provisions concerning MTFs and OTFs)) thereof, or any corresponding provision of any replacement legislation, or any codes of conduct used in connection therewith and the provisions of the Investor Compensation Act 1998 of Ireland, (b) the Companies Act 2014 of Ireland (as amended, the “Companies Act”), the Central Bank Acts 1942 to 2018 of Ireland (as amended) and any codes of conduct rules made under Section 117(1) of the Central Bank Act 1989 of Ireland (as amended), (c) the Prospectus Regulation and any rules or guidance issued under Section 1363 of the Companies Act by the Central Bank of Ireland, and (d) the Market Abuse Regulation (EU 596/2014) (as amended), the European Union (Market Abuse) Regulations 2016 (as amended) of Ireland and any rules and guidance issued by the Central Bank of Ireland under Section 1370 of the Companies Act.

Hong Kong

The New Notes may not be offered or sold by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong), or (ii) to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap.571, Laws of Hong Kong) and any rules made thereunder, or (iii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong), and no advertisement, invitation or document relating to the New Notes may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the laws of Hong Kong) other than with respect to New Notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder.

Japan

The New Notes have not been and will not be registered under the Financial Instruments and Exchange Law of Japan (the Financial Instruments and Exchange Law) and each underwriter has agreed that it will not offer or sell any New Notes, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan (which term as used herein means any person resident in Japan, including any corporation or other entity organized under the laws of Japan), or to others for re-offering or resale, directly or indirectly, in Japan or to a resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Financial Instruments and Exchange Law and any other applicable laws, regulations and ministerial guidelines of Japan.

CAUTIONARY NOTE FOR FORWARD-LOOKING INFORMATION

This prospectus, any prospectus supplement or any document incorporated by reference may contain statements that are forward-looking and therefore are subject to risks and uncertainties. All statements other than statements of historical fact are, or could be, “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Statements regarding Johnson Controls’ future financial position, sales, costs, earnings, cash flows, other measures of results of operations, synergies and integration opportunities, capital expenditures and debt levels are forward-looking statements. Words such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “should,” “forecast,” “project” or “plan” and terms of similar meaning are also generally intended to identify forward-looking statements. However, the absence of these words does not mean that a statement is not forward-looking. Johnson Controls cautions that these statements are subject to numerous important risks, uncertainties, assumptions and other factors, some of which are beyond Johnson Controls’ control, that could cause Johnson Controls’ actual results to differ materially from those expressed or implied by such forward-looking statements. Investors are therefore cautioned not to place undue reliance on any forward-looking statements. The forward-looking statements included are made only as of the date of the document in which they are included, unless otherwise specified, and, except as required by law, Johnson Controls assumes no obligation, and disclaims any obligation, to update forward-looking statements to reflect events or circumstances occurring after the date of such document.

The following are some important factors that could cause the actual results of Johnson Controls to differ from its current expectations:

10

USE OF PROCEEDS

Unless otherwise specified in a prospectus supplement accompanying this prospectus, the net proceeds from the sale of the securities to which this prospectus relates will be used for general corporate purposes. General corporate purposes may include repayment of indebtedness, acquisitions, additions to working capital, repurchase of ordinary shares, dividends, capital expenditures and investments in our subsidiaries. Net proceeds may be temporarily invested prior to use.

11

DESCRIPTION OF DEBT SECURITIES

The following is a general description of the debt securities that we and, as applicable, TFSCA, may offer from time to time. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions described below may apply to those securities will be described in the applicable prospectus supplement. We and TFSCA also may sell hybrid securities that combine certain features of debt securities and other securities described in this prospectus. As you read this section, please remember that the specific terms of a debt security as described in the applicable prospectus supplement will supplement and may modify or replace the general terms described in this section. If there are any differences between the applicable prospectus supplement and this prospectus, the applicable prospectus supplement will control. As a result, the statements we make in this section may not apply to the debt security you purchase.

JCI is the issuer of the applicable series of debt securities and TFSCA may be a co-issuer of one or more series of debt securities. JCI and TFSCA will be jointly and severally liable for all obligations under any series of debt securities that they co-issue. In this section, “Issuer” refers to JCI for any series of debt securities where it is the sole issuer or JCI and TFSCA for any series of debt securities co-issued by JCI and TFSCA. Capitalized terms used but not defined in this section have the respective meanings set forth in the indenture (as defined below).

The Issuer may issue debentures, notes or other evidences of indebtedness, which we refer to as “debt securities,” from time to time in one or more distinct series. The debt securities may be senior debt securities or subordinated debt securities, in each case with the same or various maturities, at par, a premium or at a discount. Unless otherwise indicated in the applicable prospectus supplement, the aggregate principal amount of debt securities that may be issued under the indenture is unlimited.

The debt securities will be governed by an indenture dated as of December 28, 2016 (the “indenture”), between us and U.S. Bank Trust Company, National Association (successor in interest to U.S. Bank National Association), as trustee, which is filed as an exhibit to the registration statement of which this prospectus forms a part. The indenture is subject to the provisions of the Trust Indenture Act of 1939, as in effect from time to time, that are deemed to be incorporated into the indenture and shall, to the extent applicable, be governed by those provisions. As more specifically set forth in the indenture, the trustee under the indenture has two main roles:

The statements and descriptions in this prospectus or in any prospectus supplement or any document incorporated by reference into this prospectus or applicable prospectus supplement regarding provisions of debt securities and the indenture are summaries of those provisions, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the debt securities and the indenture (including any amendments or supplements we may enter into from time to time which are permitted under the debt securities or the indenture). You should read the summary below, the applicable prospectus supplement and indenture and any related documents before making your investment decision.

The applicable prospectus supplement will set forth the terms of the debt securities or any series thereof, including, if applicable:

12

13

The indenture contains certain restrictive covenants that will apply to the Issuer and its subsidiaries unless otherwise indicated in the applicable prospectus supplement, including limitations on incurring certain secured debt and limitations on certain sale and lease-back transactions. Any such covenants and the other terms applicable to a series of debt securities will be described in the applicable prospectus supplement. For the avoidance of doubt, articles 470-1 to 470-19 of the Luxembourg law of 10 August 1915 relating to commercial companies as amended (the “Companies Act 1915”) will not apply in respect of the debt securities co-issued by TFSCA.

14

DESCRIPTION OF ORDINARY SHARES

The following description of the material terms of JCI’s ordinary shares is based on the provisions of its Irish memorandum and articles of association. This description is not complete and is subject to the applicable provisions of Irish law and our memorandum and articles of association, which are filed as exhibits to the registration statement of which this prospectus forms a part. The transfer agent and registrar for our ordinary shares is Equiniti Trust Company. Our ordinary shares are listed on the New York Stock Exchange under the ticker symbol “JCI.”

Capital Structure

Authorized and Issued Share Capital

Our authorized share capital is $22,000,000 and €40,000, divided into 2,000,000,000 ordinary shares with a par value of $0.01 per share, 200,000,000 preferred shares with a par value of $0.01 per share, and 40,000 ordinary A shares with a par value of €1.00 per share. The authorized share capital includes 40,000 ordinary A shares with a par value of €1.00 per share in order, at the time of its incorporation, to satisfy statutory requirements for the incorporation of all Irish public limited companies. We may issue shares subject to the maximum amount prescribed by our authorized share capital contained in our memorandum and articles of association.

As a matter of Irish company law, the directors of a company may issue new ordinary or preferred shares (including the grant of options and issue of warrants) without shareholder approval once authorized to do so by the memorandum and articles of association of the company or by an ordinary resolution adopted by the shareholders at a general meeting. An ordinary resolution requires over 50% of the votes cast by a company’s shareholders at a general meeting. The authority conferred can be granted for a maximum period of five years, at which point it will lapse unless renewed by the shareholders of the company by an ordinary resolution. The board of directors is authorized, under an annual authorization by shareholders pursuant to an ordinary resolution, to issue ordinary shares subject to a maximum of approximately 33% of our issued share capital. The current annual authorization will expire at the earlier of the date of our annual general meeting in 2023 or September 9, 2023 unless renewed (a renewal of the authorization will be proposed at our annual general meeting in 2023, which if approved would expire on the date of our annual general meeting in 2024 or 18 months after the date of our 2023 annual general meeting (whichever is earlier)).

Notwithstanding this authority, under the Irish Takeover Rules the board of directors would not be permitted to issue any shares, during a period when an offer has been made for us or is believed to be imminent unless the issue is (i) approved by shareholders at a general meeting, (ii) consented to by the Irish Takeover Panel on the basis it would not constitute action frustrating the offer, (iii) consented to by the Irish Takeover Panel and approved by the holders of more than 50% of our voting rights, (iv) consented to by the Irish Takeover Panel in circumstances where a contract for the issue of the shares had been entered into prior to that period, or (v) consented to by the Irish Takeover Panel in circumstances where the issue of the shares was decided by our board of directors prior to that period and either action has been taken to implement the issuance (whether in part or in full) prior to such period or the issuance was otherwise in the ordinary course of business.

The board of directors has previously represented that it will not, without prior shareholder approval, approve the issuance or use of any of the preferred shares for any defensive or anti-takeover purpose or for the purpose of implementing any shareholder rights plan. Within these limits, the board of directors may approve the issuance or use of preferred shares for capital raising, financing or acquisition needs or opportunities that has the effect of making a takeover of us or other acquisition transaction more difficult or costly, as could also be the case if the board of directors were to issue additional ordinary shares.

The authority to issue preferred shares provides us with the flexibility to consider and respond to future business needs and opportunities as they arise from time to time, including in connection with capital raising, financing, and acquisition transactions or opportunities.

15

The authorized but unissued share capital may be increased or reduced by way of an ordinary resolution of our shareholders. The shares comprising our authorized share capital may be divided into shares of such par value as the resolution shall prescribe. The rights and restrictions to which the ordinary shares will be subject are prescribed in our memorandum and articles of association.

Irish law does not recognize fractional shares held of record; accordingly, our memorandum and articles of association do not provide for the issuance of fractional shares, and our official Irish register will not reflect any fractional shares.

Dividends

Under Irish law, dividends and distributions may only be made from distributable reserves. Distributable reserves, broadly, means our accumulated realized profits less our accumulated realized losses. In addition, no distribution or dividend may be made unless our net assets are equal to, or in excess of, the aggregate of our called up share capital plus undistributable reserves and the distribution does not reduce our net assets below such aggregate. Undistributable reserves include the share premium account, the par value of shares acquired by us and the amount by which our accumulated unrealized profits, so far as not previously utilized by any capitalization, exceed our accumulated unrealized losses, so far as not previously written off in a reduction or reorganization of capital.

The determination as to whether or not we have sufficient distributable reserves to fund a dividend must be made by reference to our “relevant financial statements.” The “relevant financial statements” will be either the last set of unconsolidated annual audited financial statements or unaudited financial statements prior to the declaration of a dividend prepared in accordance with the Irish Companies Act, which give a “true and fair view” of our unconsolidated financial position and accord with accepted accounting practice. The relevant financial statements must be filed in the Companies Registration Office (the official public registry for companies in Ireland).

The mechanism as to who declares a dividend and when a dividend shall become payable is governed by our articles of association, which authorize the directors to declare such dividends as appear justified from our profits without the approval of the shareholders at a general meeting. The board of directors may also recommend a dividend to be approved and declared by the shareholders at a general meeting. Although the shareholders may direct that the payment be made by distribution of assets, shares or cash, no dividend issued may exceed the amount recommended by the directors. The dividends can be declared and paid in the form of cash or non-cash assets.

Our directors may deduct from any dividend payable to any shareholder all sums of money (if any) payable by him or her to us in relation to our shares. Our directors are also entitled to issue shares with preferred rights to participate in dividends we declare. The holders of such preferred shares may, depending on their terms, be entitled to claim arrears of a declared dividend out of subsequently declared dividends in priority to ordinary shareholders.

Preemptive Rights and Advance Subscription Rights

Certain statutory pre-emption rights apply automatically in favor of our shareholders where our shares are to be issued for cash (including pursuant to non-compensatory options). Statutory preemption rights do not apply (i) where shares are issued for non-cash consideration (such as in a stock-for-stock acquisition), (ii) to the issue of non-equity shares (that is, shares that have the right to participate only up to a specified amount in any income or capital distribution) or (iii) where shares are issued pursuant to an employee option or similar equity plan. In addition, and without prejudice to any existing authorities granted to the board of directors, the board of directors is authorized, under an annual authorization by shareholders pursuant to a special resolution, to issue ordinary shares without the application of preemption rights of up to approximately 5% of our issued share capital. The

16

current annual authorization will expire at the earlier of the date of our annual general meeting in 2023 or September 9, 2023 unless renewed (a renewal of the authorization will be proposed at our annual general meeting in 2023, which if approved would expire on the date of our annual general meeting in 2024 or 18 months after the date of our 2023 annual general meeting (whichever is earlier)).

A special resolution requires not less than 75% of the votes cast by our shareholders at a general meeting. If the opt-out is not renewed, shares issued for cash must be offered to our pre-existing shareholders pro rata to their existing shareholding in accordance with the statutory preemption rights described above before the shares can be issued to any new shareholders.

Issuance of Warrants and Options

Our articles of association provide that, subject to any shareholder approval requirement under any laws, regulations or the rules of any stock exchange to which we are subject, the board is authorized, from time to time, in its discretion, to grant such persons, for such periods and upon such terms as the board deems advisable, options to purchase such number of shares of any class or classes or of any series of any class as the board may deem advisable, and to cause warrants or other appropriate instruments evidencing such options to be issued. The issuance of warrants or options is subject to the same requirements for shareholder authority and statutory preemption rights as applies to the issue of ordinary shares described under the headings “—Capital Structure—Authorized and Issued Share Capital” and “—Preemptive Rights and Advance Subscription Rights” in this section and the number of shares capable of being issued under options and warrants are aggregated with the number of shares issued under those authorizations for determining the utilization of those authorizations. The board may issue shares upon exercise of warrants or options without shareholder approval or authorization provided that the original warrants or options were issued when valid authorization was in place.

Share Repurchases and Redemptions

Overview

Article 3 of our articles of association provides that any ordinary share which we have acquired or agreed to acquire shall be deemed to be a redeemable share. Accordingly, for Irish company law purposes, the repurchase of ordinary shares by us will technically be effected as a redemption of those shares as described below. If our articles of association did not contain Article 3(d), repurchases of our ordinary shares would be subject to many of the same rules that apply to purchases of our ordinary shares by subsidiaries described below, including the shareholder approval requirements described below and the requirement that any on-market purchases be effected on a “recognized stock exchange.” Except where otherwise noted, when we refer elsewhere in this prospectus to repurchasing or buying back our ordinary shares, we are referring to the redemption of ordinary shares by us pursuant to Article 3(d) of the articles of association or the purchase of our ordinary shares by a subsidiary of ours, in each case in accordance with our articles of association and Irish company law as described below.

Repurchases and Redemptions by Us

Under Irish law, a company can issue redeemable shares and redeem them out of distributable reserves or the proceeds of a new issue of shares for that purpose. The issue of redeemable shares may only be made by us where the nominal value of the issued share capital that is not redeemable is not less than 10% of the aggregate of the par value and share premium in respect of the allotment of our shares together with the par value of any shares acquired by us. All redeemable shares must also be fully paid and the terms of redemption of the shares must provide for payment on redemption. Redeemable shares may, upon redemption, be cancelled or held in treasury. Shareholder approval will not be required to redeem our ordinary shares. Our board of directors will also be entitled to issue preferred shares which may be redeemed at either our option or that of the shareholder, depending on the terms of such preferred shares.

17

Repurchased and redeemed shares may be cancelled or held as treasury shares. The nominal value of treasury shares held by us at any time must not exceed 10% of our company capital (consisting of the aggregate of the par value and share premium in respect of the allotment of our shares together with the par value of any shares acquired by us). While we hold shares as treasury shares, we cannot exercise any voting rights in respect of those shares. We may cancel or reissue treasury shares subject to certain conditions.

Purchases by Our Subsidiaries

Under Irish law, it may be permissible for an Irish or non-Irish subsidiary to purchase our shares either on-market or off-market. A general authority of our shareholders is required to allow a subsidiary of ours to make on-market purchases of our ordinary shares; however, as long as this general authority has been granted, no specific shareholder authority for a particular on-market purchase by a subsidiary of our ordinary shares is required. Such an authority has been adopted by our shareholders. We have sought such general authority, which must expire no later than 18 months after the date on which it was granted, at previous annual general meetings and expect to seek to renew such authority at subsequent annual general meetings. In order for a subsidiary of ours to make an on-market purchase of our shares, such shares must be purchased on a “recognized stock exchange.” The New York Stock Exchange, on which our shares are listed, is a recognized stock exchange for this purpose under Irish company law. For an off-market purchase by a subsidiary of ours, the proposed purchase contract must be authorized by special resolution of our shareholders before the contract is entered into. The person whose shares are to be bought back cannot vote in favor of the special resolution and, from the date of the notice of the meeting at which the resolution approving the contract is to be proposed, the purchase contract must be on display or must be available for inspection by shareholders at our registered office.

The number of shares held by our subsidiaries at any time will count as treasury shares and will be included in any calculation of the permitted treasury share threshold of 10% of the aggregate of the par value and share premium in respect of the allotment of our shares together with the par value of any shares acquired by us. While a subsidiary holds our shares, it cannot exercise any voting rights in respect of those shares. The acquisition of our shares by a subsidiary must be funded out of distributable reserves of the subsidiary.

Lien on Shares, Calls on Shares and Forfeiture of Shares

Our articles of association provide that we will have a first and paramount lien on every share for all moneys payable, whether presently due or not, in respect of such share. Subject to the terms of their allotment, directors may call for any unpaid amounts in respect of any shares to be paid, and if payment is not made, the shares may be forfeited. These provisions are standard inclusions in the articles of association of an Irish company limited by shares, such as us.

Bonus Shares

Under our articles of association, the board of directors may resolve to capitalize any amount credited to any reserve or fund available for distribution or the share premium account or other undistributable reserve of ours for issuance and distribution to shareholders as fully paid up bonus shares on the same basis of entitlement as would apply in respect of a dividend distribution.

Consolidation and Division; Subdivision

Under our articles of association, we may by ordinary resolution consolidate and divide all or any of our share capital into shares of larger par value than its existing shares or subdivide our shares into smaller amounts than is fixed by our articles of association.

Reduction of Share Capital

We may, by ordinary resolution, reduce our authorized but unissued share capital in any way and reduce the nominal value of any of its shares. We also may, by special resolution and subject to confirmation by the Irish

18

High Court (or as otherwise permitted under the Irish Companies Act), reduce or cancel our issued share capital in any way.

General Meetings of Shareholders

We are generally required to hold an annual general meeting at intervals of no more than fifteen months, provided that an annual general meeting is held in each calendar year, no more than nine months after our fiscal year-end.

Our articles of association provide that shareholder meetings may be held outside of Ireland (subject to compliance with the Irish Companies Act). Where a company holds its annual general meeting or extraordinary general meeting outside of Ireland, the Irish Companies Act requires that the company, at its own expense, make all necessary arrangements to ensure that members can by technological means participate in the meeting without leaving Ireland (unless all of the members entitled to attend and vote at the meeting consent in writing to the meeting being held outside of Ireland).

Extraordinary general meetings may be convened by (i) the board of directors, (ii) on requisition of the shareholders holding not less than 10% of the paid up share capital of our shares carrying voting rights or (iii) on requisition of our auditors. Extraordinary general meetings are generally held for the purposes of approving shareholder resolutions as may be required from time to time.

Notice of a general meeting must be given to all of our shareholders and to our auditors. Our articles of association provide that the maximum notice period is 60 days. The minimum notice periods are 21 days’ notice in writing for an annual general meeting or an extraordinary general meeting to approve a special resolution and 14 days’ notice in writing for any other extraordinary general meeting. In each case, the notice period excludes the date of mailing and the date of the meeting and is in addition to two days for deemed delivery where this is by electronic means. General meetings may be called by shorter notice, but only with the consent of our auditors and all of the shareholders entitled to attend and vote thereat. Because of the 21-day and 14-day requirements described in this paragraph, our articles of association include provisions reflecting these requirements of Irish law.

In the case of an extraordinary general meeting convened by our shareholders, the proposed purpose of the meeting must be set out in the requisition notice. The requisition notice can contain any resolution. Upon receipt of this requisition notice, the board of directors has 21 days to convene a meeting of our shareholders to vote on the matters set out in the requisition notice. This meeting must be held within two months of the receipt of the requisition notice. If the board of directors does not convene the meeting within such 21-day period, the requisitioning shareholders, or any of them representing more than one half of the total voting rights of all of them, may themselves convene a meeting, which meeting must be held within three months of the receipt of the requisition notice.

The only matters which must, as a matter of Irish company law, be transacted at an annual general meeting are the presentation of the annual accounts, balance sheet and reports of the directors and auditors, the appointment of auditors and the fixing of the auditor’s remuneration (or delegation of same). If no resolution is made in respect of the reappointment of an auditor at an annual general meeting, the previous auditor will be deemed to have continued in office. Directors are elected by the affirmative vote of a majority of the votes cast by shareholders at an annual general meeting and, pursuant to our articles of association, serve for one-year terms. Any nominee for director who does not receive a majority of the votes cast is not elected to the board. However, because Irish law requires a minimum of two directors at all times, in the event that an election results in no directors being elected, each of the two nominees receiving the greatest number of votes in favor of his or her election shall hold office until his or her successor shall be elected. In the event that an election results in only one director being elected, that director shall be elected and shall serve for a one-year term, and the nominee receiving the greatest number of votes in favor of their election shall hold office until his or her successor shall be elected.

19

If the directors become aware that our net assets are half or less of the amount of our called-up share capital, the directors must convene an extraordinary general meeting of our shareholders not later than 28 days from the date that they learn of this fact. This meeting must be convened for the purposes of considering whether any, and if so what, measures should be taken to address the situation.

Voting

General

Where a poll is demanded at a general meeting, every shareholder shall have one vote for each ordinary share that he or she holds as of the record date for the meeting. Voting rights on a poll may be exercised by shareholders registered in our share register as of the record date for the meeting or by a duly appointed proxy of such a registered shareholder, which proxy need not be a shareholder. Where interests in shares are held by a nominee trust company this company may exercise the rights of the beneficial holders on their behalf as their proxy. All proxies must be appointed in the manner prescribed by the Irish Companies Act. Our articles of association permit the appointment of proxies by the shareholders to be notified by us electronically, when permitted by the directors.

Our articles of association provide that all resolutions shall be decided by a show of hands unless a poll is demanded by the chairman, by at least three shareholders as of the record date for the meeting or by any shareholder or shareholders holding not less than 10% of the total voting rights of ours as of the record date for the meeting. Each of our shareholders of record as of the record date for the meeting has one vote at a general meeting on a show of hands.

In accordance with our articles of association, our directors may from time to time cause us to issue preferred shares. These preferred shares may have such voting rights as may be specified in the terms of such preferred shares (e.g., they may carry more votes per share than ordinary shares or may entitle their holders to a class vote on such matters as may be specified in the terms of the preferred shares).

Treasury shares will not be entitled to vote at general meetings of shareholders

Supermajority Voting

Irish company law requires “special resolutions” of the shareholders at a general meeting to approve certain matters. A special resolution requires not less than 75% of the votes cast by our shareholders at a general meeting. This may be contrasted with “ordinary resolutions,” which require a simple majority of the votes cast by our shareholders at a general meeting. Examples of matters requiring special resolutions include:

20

A scheme of arrangement with shareholders requires a court order from the Irish High Court and the approval of (1) 75% of the voting shareholders by value and (2) 50% in number of the voting shareholders, at a meeting called to approve the scheme.

Variation of Class Rights Attaching to Shares

Variation of all or any special rights attached to any class of our shares is addressed in our articles of association as well as the Irish Companies Act. Any variation of class rights attaching to our issued shares must be approved by a special resolution of the shareholders of the class affected.

Quorum for General Meetings

The presence, in person or by proxy, of the holders of our ordinary shares outstanding which entitle the holders to a majority of the voting power of shares outstanding constitutes a quorum for the conduct of business. No business may take place at a general meeting if a quorum is not present in person or by proxy. The board of directors has no authority to waive quorum requirements stipulated in our articles of association. Abstentions and broker non-votes will be counted as present for purposes of determining whether there is a quorum in respect of the proposals.

Inspection of Books and Records

Under Irish law, shareholders have the right to: (1) receive a copy of our memorandum and articles of association and any act of the Irish government which alters our memorandum of association; (2) inspect and obtain copies of our minutes of general meetings and resolutions; (3) inspect and receive a copy of the register of shareholders, register of directors and secretaries, register of directors’ interests and other statutory registers maintained by us; (4) receive copies of financial statements and directors’ and auditors’ reports which have previously been sent to shareholders prior to an annual general meeting; and (5) receive financial statements of a subsidiary company of ours which have previously been sent to shareholders prior to an annual general meeting for the preceding ten years. Our auditors will also have the right to inspect all of our books, records and vouchers. The auditors’ report must be circulated to the shareholders with our audited financial statements 21 days before the annual general meeting and must be laid before the shareholders at our annual general meeting.

Acquisitions and Appraisal Rights

There are a number of mechanisms for acquiring an Irish public limited company, including:

21

Under Irish law, there is no requirement for a company’s shareholders to approve a sale, lease or exchange of all or substantially all of a company’s property and assets. However, our articles of association provide that the affirmative vote of the holders of a majority of the outstanding voting shares on the relevant record date is required to approve a sale, lease or exchange of all or substantially all of its property or assets.

Disclosure of Interests in Shares

Under the Irish Companies Act, there is a notification requirement for shareholders who acquire or cease to be interested in 3% of the shares of an Irish public limited company. A shareholder of ours must therefore make such a notification to us if as a result of a transaction the shareholder will be interested in 3% or more of our shares; or if as a result of a transaction a shareholder who was interested in more than 3% of our shares ceases to be so interested. Where a shareholder is interested in more than 3% of our shares, any alteration of his or her interest that brings his or her total holding through the nearest whole percentage number, whether an increase or a reduction, must be notified to us. The relevant percentage figure is calculated by reference to the aggregate par value of the shares in which the shareholder is interested as a proportion of the entire par value of our share capital. Where the percentage level of the shareholder’s interest does not amount to a whole percentage this figure may be rounded down to the next whole number. All such disclosures should be notified to us within 5 business days of the transaction or alteration of the shareholder’s interests that gave rise to the requirement to notify. Where a person fails to comply with the notification requirements described above no right or interest of any kind whatsoever in respect of any of our shares concerned, held by such person, shall be enforceable by such person, whether directly or indirectly, by action or legal proceeding. However, such person may apply to the court to have the rights attaching to the shares concerned reinstated.

In addition to the above disclosure requirement, under the Irish Companies Act we may by notice in writing require a person whom we know or have reasonable cause to believe to be, or at any time during the three years immediately preceding the date on which such notice is issued, to have been interested in shares comprised in our relevant share capital to: (a) indicate whether or not it is the case, and (b) where such person holds or has during that time held an interest in our shares, to give such further information as may be required by us including particulars of such person’s own past or present interests in our shares. Any information given in response to the notice is required to be given in writing within such reasonable time as may be specified in the notice.

Where such a notice is served by us on a person who is or was interested in our shares and that person fails to give us any information required within the reasonable time specified, we may apply to court for an order directing that the affected shares be subject to certain restrictions.

Under the Irish Companies Act, the restrictions that may be placed on the shares by the court are as follows:

22

Where our shares are subject to these restrictions, the court may order the shares to be sold and may also direct that the shares shall cease to be subject to these restrictions. Failure to comply with such a court order is a criminal offence.

Anti-Takeover Provisions

Business Combinations with Interested Shareholders

Our articles of association include a provision similar to Section 203 of the Delaware General Corporation Law, which generally prohibits us from engaging in a business combination with an interested shareholder for a period of three years following the date the person became an interested shareholder, unless, in general:

A “business combination” is generally defined as a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested shareholder. An “interested shareholder” is generally defined as a person who, together with affiliates and associates, owns or, within three years prior to the date in question, owned 15% or more of our outstanding voting shares.

Shareholder Rights Plans and Share Issuances

Irish law does not expressly prohibit companies from issuing share purchase rights or adopting a shareholder rights plan as an anti-takeover measure. However, there is no directly relevant case law on the validity of such plans under Irish law, and shareholder approval may be required under Irish law to implement such a plan. In addition, such a plan would be subject to the Irish Takeover Rules described below.

Subject to the Irish Takeover Rules described below, the board also has power to issue any of our authorized and unissued shares on such terms and conditions as it may determine and any such action should be taken in our best interests. It is possible, however, that the terms and conditions of any issue of preferred shares could discourage a takeover or other transaction that holders of some or a majority of the ordinary shares believe to be in their best interests or in which holders might receive a premium for their shares over the then market price of the shares. The board of directors represents that it will not, without prior shareholder approval, approve the issuance or use of any of the preferred shares for any defensive or anti-takeover purpose or for the purpose of implementing any shareholder rights plan. Within these limits, the board of directors may approve the issuance or use of preferred shares for capital raising, financing or acquisition needs or opportunities that has the effect of making a takeover of us or other acquisition transactions more difficult or costly, as could also be the case if the board of directors were to issue additional ordinary shares.

Irish Takeover Rules and Substantial Acquisition Rules

A transaction by virtue of which a third party is seeking to acquire 30% or more of the voting rights of our shares will be governed by the Irish Takeover Panel Act 1997 and the Irish Takeover Rules made thereunder and will be regulated by the Irish Takeover Panel. The “General Principles” of the Irish Takeover Rules and certain important aspects of the Irish Takeover Rules are described below.

23

General Principles

The Irish Takeover Rules are built on the following General Principles which will apply to any transaction regulated by the Irish Takeover Panel:

Mandatory Bid

Under certain circumstances, a person who acquires our shares or other voting rights may be required under the Irish Takeover Rules to make a mandatory cash offer for our remaining outstanding shares at a price not less than the highest price paid for the shares by the acquirer (or any parties acting in concert with the acquirer) during the previous 12 months. This mandatory bid requirement is triggered if, unless the Irish Takeover Panel otherwise consents, an acquisition of shares would (i) increase the aggregate holding of an acquirer (including the holdings of any parties acting in concert with the acquirer) to shares representing 30% or more of the voting rights in us, or (ii) in the case of a person holding (together with its concert parties) shares representing 30% or more of the voting rights in us, after giving effect to the acquisition, increase the percentage of the voting rights held by that person (together with its concert parties) by 0.05% within a 12-month period. Any person (excluding any parties acting in concert with the holder) holding shares representing more than 50% of the voting rights of a company is not subject to these mandatory offer requirements in purchasing additional securities.

Voluntary Bid; Requirements to Make a Cash Offer and Minimum Price Requirements

A voluntary offer is an offer that is not a mandatory offer. If a bidder or any of its concert parties acquire our ordinary shares within the period of three months prior to the commencement of the offer period, the offer price must be not less than the highest price paid for our ordinary shares by the bidder or its concert parties during that period. The Irish Takeover Panel has the power to extend the “look back” period to 12 months if the Irish Takeover Panel, having regard to the General Principles, believes it is appropriate to do so.

If the bidder or any of its concert parties has acquired our ordinary shares (i) during the period of 12 months prior to the commencement of the offer period which represent more than 10% of our total ordinary shares or (ii) at any time after the commencement of the offer period, the offer shall be in cash (or accompanied by a full

24

cash alternative) and the price per ordinary share shall be not less than the highest price paid by the bidder or its concert parties during, in the case of (i), the period of 12 months prior to the commencement of the offer period and, in the case of (ii), the offer period. The Irish Takeover Panel may apply this rule to a bidder who, together with its concert parties, has acquired less than 10% of our total ordinary shares in the 12-month period prior to the commencement of the offer period if the Irish Takeover Panel, having regard to the General Principles, considers it just and proper to do so.

An offer period will generally commence from the date of the first announcement of the offer or proposed offer.

Substantial Acquisition Rules

The Irish Takeover Rules also contain rules governing substantial acquisitions of shares which restrict the speed at which a person may increase his or her holding of shares and rights over shares to an aggregate of between 15% and 30% of the voting rights of our shares. Except in certain circumstances, an acquisition or series of acquisitions of shares or rights over shares representing 10% or more of the voting rights of our shares is prohibited, if such acquisition(s), when aggregated with shares or rights already held, would result in the acquirer holding 15% or more but less than 30% of the voting rights of our shares and such acquisitions are made within a period of seven days. These rules also require accelerated disclosure of acquisitions of shares or rights over shares relating to such holdings.

Frustrating Action

Under the Irish Takeover Rules, our board of directors is not permitted to take any action which might frustrate an offer for our shares once the board of directors has received an approach which may lead to an offer or has reason to believe an offer is imminent except as noted below. Potentially frustrating actions such as (i) the issue of shares, options or convertible securities, or the redemption or purchase of our securities (other than under a contract entered into prior to the announcement of the offer or the board of directors having reason to believe an offer is imminent), (ii) material acquisitions or disposals, (iii) entering into contracts other than in the ordinary course of business or (iv) any action, other than seeking alternative offers, which may result in frustration of an offer, are prohibited during the course of an offer or at any time during which the board has reason to believe an offer is imminent. Exceptions to this prohibition are available where:

Corporate Governance

Our articles of association delegate the day-to-day management of us to the board of directors. The board of directors may then delegate the management of us to committees, executives or to a management team, but regardless, the directors will remain responsible, as a matter of Irish law, for the proper management of our affairs.

Our corporate governance guidelines and general approach to corporate governance as reflected in our memorandum and articles of association and our internal policies and procedures are guided by U.S. practice and

25

applicable federal securities laws and regulations and the requirements of the New York Stock Exchange. Although we are an Irish public limited company, we are not subject to the listing rules of Euronext Dublin or the listing rules of the U.K. Financial Conduct Authority and we are therefore not subject to, nor will we adopt, the U.K. Corporate Governance Code, any guidelines issued by the Investment Association or the Pre-Emption Group Statement of Principles, or any other non-statutory Irish or U.K. governance standards or guidelines. While there are many similarities and overlaps between the U.S. corporate governance standards applied by us and the U.K. Corporate Governance Code and other Irish/U.K. governance standards or guidelines, there are differences, in particular relating to the extent of the authorization to issue share capital and effect share repurchases that may be granted to the board and the criteria for determining the independence of directors.

Duration; Dissolution; Rights upon Liquidation

Our duration is unlimited. We may be dissolved and wound up at any time by way of either a shareholders’ voluntary winding up or a creditors’ winding up. In the case of a shareholders’ voluntary winding up, the consent of not less than 75% of the votes cast by our shareholders is required. We may also be dissolved by way of court order on the application of a creditor or the Director of Corporate Enforcement (where the court is satisfied on a petition of the Director of Corporate Enforcement that it is in the public interest that we should be would up), or by the Companies Registration Office (by way of strike-off) as an enforcement measure where we have failed to file certain returns.

The rights of the shareholders to a return of our assets on dissolution or winding up, following the settlement of all claims of creditors, may be prescribed in our memorandum and articles of association or the terms of any preferred shares issued by our directors from time to time. The holders of preferred shares in particular may have the right to priority in a dissolution or winding up of us. If the articles of association contain no specific provisions in respect of a dissolution or winding up then, subject to the priorities of any creditors, the assets will be distributed to shareholders in proportion to the paid-up par value of the shares held. Our articles of association provide that our ordinary shareholders are entitled to participate pro rata in a winding up, but their right to do so may be subject to the rights of any preferred shareholders to participate under the terms of any series or class of preferred shares.

Stock Exchange Listing

Our ordinary shares are listed on the New York Stock Exchange under the symbol “JCI”.

Uncertificated Shares

Pursuant to the Irish Companies Act a shareholder is entitled to be issued a share certificate on request and subject to payment of a nominal fee.

Transfer and Registration of Shares

Our share register is maintained by our transfer agent. Registration in this share register is determinative of membership in us. A shareholder of ours who holds shares beneficially is not the holder of record of such shares. Instead, the depository (for example, Cede & Co., as nominee for DTC) or other nominee is the holder of record of such shares. Accordingly, a transfer of shares from a person who holds such shares beneficially to a person who also holds such shares beneficially through the same depository or other nominee will not be registered in our official share register, as the depository or other nominee will remain the record holder of such shares.

A written instrument of transfer is required under Irish law in order to register on our official share register any transfer of shares (i) from a person who holds such shares directly to any other person, (ii) from a person who holds such shares beneficially to a person who holds such shares directly, or (iii) from a person who holds such shares beneficially to another person who holds such shares beneficially where the transfer involves a

26

change in the depository or other nominee that is the record owner of the transferred shares. An instrument of transfer also is required for a shareholder who directly holds shares to transfer those shares into his or her own broker account (or vice versa). Such instruments of transfer may give rise to Irish stamp duty, which must be paid prior to registration of the transfer on our official Irish share register.

We may, in our absolute discretion, pay or cause one of our affiliates to pay any stamp duty. Our articles of association provide that, in the event of any such payment, we shall be entitled to (i) seek reimbursement from the buyer, (ii) set-off the amount of the stamp duty against future dividends on such shares, and (iii) claim a first and permanent lien on our ordinary shares acquired by such buyer and any dividends paid on such shares. Parties to a share transfer may assume that any stamp duty arising in respect of a transaction in our ordinary shares has been paid unless one or both of such parties is otherwise notified by us.

Our articles of association delegate to our Secretary (or his or her nominee) the authority to execute an instrument of transfer on behalf of a transferring party. In order to help ensure that the official share register is regularly updated to reflect trading of our ordinary shares occurring through normal electronic systems, we regularly produce any required instruments of transfer in connection with any transactions for which we pay stamp duty (subject to the reimbursement and set-off rights described above). In the event that we notify one or both of the parties to a share transfer that we believe stamp duty is required to be paid in connection with such transfer and that we will not pay such stamp duty, such parties may either themselves arrange for the execution of the required instrument of transfer (and may request a form of instrument of transfer from us for this purpose) or request that we execute an instrument of transfer on behalf of the transferring party in a form determined by us. In either event, if the parties to the share transfer have the instrument of transfer duly stamped (to the extent required) and then provide it to our transfer agent, the transferee will be registered as the legal owner of the relevant shares on our official Irish share register (subject to the matters described below).

Our directors have general discretion to decline to register an instrument of transfer unless the transfer is in respect of one class of shares only, the instrument of transfer is accompanied by the certificate of shares to which it relates and such other evidence as the directors may reasonably require to show the right of the transferor to make the transfer, a fee of €10 or such lesser sum is paid to us, the instrument of transfer is in favor of not more than four transferees and it is lodged at our registered office or such other place as the board of directors may appoint.

The registration of transfers may be suspended by the directors at such times and for such period, not exceeding in the whole 30 days in each year, as the directors may from time to time determine.

Formation; Fiscal Year; Registered Office

We were incorporated in Ireland as a public limited company on May 9, 2014 (under the name “Tyco International plc”) with company registration number 543654. Our fiscal year ends on September 30 of each year and our registered address is One Albert Quay, Cork, T12 X8N6, Ireland.

No Sinking Fund

The ordinary shares have no sinking fund provisions.

No Liability for Further Calls or Assessments

When the ordinary shares offered hereby are issued, they will be duly and validly issued, fully paid and non-assessable.

DESCRIPTION OF PREFERRED SHARES

The following description of the material terms of JCI’s preferred shares is based on the provisions of its Irish memorandum and articles of association. This description is not complete and is subject to the applicable provisions of Irish law and our memorandum and articles of association, which are filed as exhibits to the registration statement of which this prospectus forms a part.

The board of directors is authorized to issue our entire authorized preferred share capital (i.e., up to a maximum of up to 200,000,000 preferred shares with a par value of $0.01 per share), under an annual authorization by shareholders pursuant to an ordinary resolution, subject to an overall limit of approximately 33% of our issued share capital not being exceeded. The current annual authorization will expire at the earlier of the date of our annual general meeting in 2023 or September 9, 2023 unless renewed (a renewal of the authorization will be proposed at our annual general meeting in 2023, which if approved, would expire on the date of our annual general meeting in 2024 or 18 months after the date of our 2023 annual general meeting (whichever is earlier)). Such authorization includes preferred shares issued on a non-pre-emptive basis, with discretion as to the terms attaching to the preferred shares, including as to voting, dividend and conversion rights and priority relative to other classes of shares with respect to dividends and upon a liquidation.

Notwithstanding this authority, under the Irish Takeover Rules the board of directors would not be permitted to issue any of our shares, including the preferred shares, during a period when an offer has been made for us or is believed to be imminent unless the issue is (i) approved by shareholders at a general meeting; (ii) consented to by the Irish Takeover Panel on the basis it would not constitute action frustrating the offer; (iii) consented to by the Irish Takeover Panel and approved by the holders of more than 50% of our voting rights; (iv) consented to by the Irish Takeover Panel in circumstances where a contract for the issue of the shares had been entered into prior to that period; or (v) consented to by the Irish Takeover Panel in circumstances where the issue of the shares was decided by our board of directors prior to that period and either action has been taken to implement the issuance (whether in part or in full) prior to such period or the issuance was otherwise in the ordinary course of business.

Our board of directors has previously represented that it will not, without prior shareholder approval, approve the issuance or use of any of the preferred shares for any defensive or anti-takeover purpose or for the purpose of implementing any shareholder rights plan. Within these limits, the board of directors may approve the issuance or use of preferred shares for capital raising, financing or acquisition needs or opportunities that has the effect of making a takeover of us or other acquisition transaction more difficult or costly, as could also be the case if the board of directors were to issue additional ordinary shares.

Our articles of association entitle the board of directors, without shareholder approval, to determine the terms of the preferred shares issued by us. Preferred shares may be preferred as to dividends, rights on a winding up or voting in such manner as our directors may resolve. The preferred shares may also be redeemable at the option of the holder of the preferred shares or at our option, and may be convertible into or exchangeable for shares of any other class or classes of our securities, depending on the terms of such preferred shares.

28

DESCRIPTION OF DEPOSITARY SHARES

We may, at our option, elect to offer fractional interests in preferred shares instead of a full preferred share. In that event, depositary receipts may be issued for depositary shares, each of which will represent a fraction of a share of a particular class or series of preferred shares, as described in the applicable prospectus supplement and/or other offering material.

Any series of preferred shares represented by depositary shares will be deposited under a deposit agreement between us and the depositary. The prospectus supplement and/or other offering material relating to a series of depositary shares will set forth the name and address of the depositary for the depositary shares and summarize the material provisions of the deposit agreement. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a preferred share represented by such depositary share, to all the rights and preferences of the preferred shares represented by such depositary share, including dividend and liquidation rights and any right to convert or exchange the preferred shares into other securities.

The applicable prospectus supplement will describe the particular terms of any depositary shares we offer. You should review the documents pursuant to which the depositary shares will be issued, which will be described in more detail in the applicable prospectus supplement.

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts for the purchase or sale of our debt securities, including debt securities co-issued by TFSCA, or equity securities or securities of third parties including any of our affiliates, a basket of such securities, an index or indices of such securities or any combination of the above as specified in the applicable prospectus supplement.

We may issue purchase contracts obligating holders to purchase from us, and obligating us to sell to holders, at a future date, a specified or varying number of securities at a purchase price, which may be based on a formula. Alternatively, we may issue purchase contracts obligating us to purchase from holders, and obligating holders to sell to us, at a future date, a specified or varying number of securities at a purchase price, which may be based on a formula. We may satisfy our obligations, if any, with respect to any purchase contract by delivering the subject securities or by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will specify the methods by which the holders may purchase or sell such securities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, and these payments may be unsecured or prefunded and may be paid on a current or deferred basis. The purchase contracts may require holders thereof to secure their obligations under the contracts in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued as described in the applicable prospectus supplement.

DESCRIPTION OF WARRANTS

We may from time to time issue warrants, in one or more series, to purchase our debt securities, including debt securities co-issued by TFSCA, or equity securities. We may offer warrants separately or together with one or more additional warrants, debt securities, preferred shares or ordinary shares, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. If we issue warrants as part of a unit, the accompanying supplement will specify whether those warrants may be separated from the other securities in the unit prior to the warrants’ expiration date.

Below is a description of certain general terms and provisions of the warrants that we may offer. Further terms of the warrants will be described in the applicable prospectus supplement. You should read the particular terms of any warrants we offer described in the related prospectus supplement, together with any warrant agreement relating to the particular warrant, for provisions that may be important to you.

The applicable prospectus supplement will contain, where applicable, the following terms of and other information relating to the warrants:

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit may also include debt obligations, including debt securities co-issued by TFSCA, or other securities of third parties not affiliated with us, such as U.S. Treasury securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The applicable unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or any time before a specified date.

The applicable prospectus supplement will describe the terms of the units offered pursuant to it, including one or more of the following:

The preceding description and any description of units in the applicable prospectus supplement does not purpose to be complete and is subject to and is qualified in its entirety by reference to each unit agreement and, if applicable, collateral arrangements relating to such units.

32

PLAN OF DISTRIBUTION

We and, as applicable, TFSCA, may sell the offered securities through agents, to or through underwriters or dealers, directly to one or more purchasers, through a combination of any of these methods of sale or through any other methods described in a prospectus supplement. The distribution of securities may be effected, from time to time, in one or more transactions, including block transactions and transactions on the New York Stock Exchange or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities. We and, as applicable, TFSCA, will identify the specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation and the purchase price and the proceeds we and, as applicable, TFSCA, will receive from the sale in a prospectus supplement.

In connection with any particular offering pursuant to this shelf registration statement, an underwriter may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of the securities or preventing or retarding a decline in the market price of the securities. As a result, the price of the securities may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the New York Stock Exchange or otherwise and, if commenced, may be discontinued at any time.
