Recent Developments

Proposed Acquisition of Manitowoc Ice

On March 2, 2022, Pentair Commercial Ice LLC, an indirect, wholly owned subsidiary of Pentair (“Pentair Ice”), and Pentair entered into the Purchase Agreement with Welbilt, Inc. (“Welbilt”), pursuant to which Pentair Ice agreed to acquire the issued and outstanding equity securities of certain subsidiaries of Welbilt and certain other assets, rights, and properties, and assume certain liabilities, comprising Welbilt’s Manitowoc Ice business (“Manitowoc Ice”), for an aggregate purchase price of $1.6 billion, subject to customary adjustments contemplated by the Purchase Agreement.

Manitowoc Ice is a leading designer, manufacturer, and distributor of commercial ice machines in the United States and globally. With a global installed base of approximately 1 million units and more than 200 models of commercial ice machines worldwide, Manitowoc Ice has excelled at delivering differentiated product innovation, food safety and sustainability in icemaking. Manitowoc Ice employs approximately 800 team members and operates facilities in Manitowoc, Wisconsin, Monterrey, Mexico and Hangzhou, China. Manitowoc Ice generated $315 million in revenue in 2021.

We intend to use the net proceeds of this offering and the term loan financing (as defined herein), together with cash on hand and/or borrowings under our revolving credit facility, and, if necessary, borrowings under our committed bridge facility, to finance the Manitowoc Ice acquisition and to pay related fees and expenses. See “Use of Proceeds.” We expect the Manitowoc Ice acquisition to close in the third quarter of calendar year 2022, subject to necessary regulatory approvals and satisfaction of certain customary closing conditions.

The Purchase Agreement contains certain termination rights for each party, including the right of each party to terminate the Purchase Agreement on or after January 14, 2023 if regulatory approvals have not been received and the transactions contemplated by the Purchase Agreement have not been consummated by such date. The consummation of the Manitowoc Ice acquisition is not contingent upon the consummation of this offering and this offering is not contingent upon the consummation of the Manitowoc Ice acquisition. See “Description of Notes — Special Mandatory Redemption.”

Financing of Proposed Acquisition

In connection with the Purchase Agreement, Pentair Finance and Pentair entered into a bridge facility commitment letter (the “bridge facility commitment letter”) pursuant to which a group of financial institutions committed to provide a 364-day senior unsecured bridge facility in an aggregate principal amount of $1.6 billion (the “bridge facility”) for the purpose of financing a portion of the purchase price for the Manitowoc Ice acquisition and to pay related fees and expenses. Unless we are unable to complete this offering and consummate the term loan financing, we do not expect to borrow under the committed bridge facility. See “Use of Proceeds.”

On March 24, 2022, Pentair Finance and Pentair entered into a new loan agreement (the “loan agreement”) with a syndicate of financial institutions, pursuant to which such financial institutions have committed to provide Pentair Finance with a senior unsecured term loan facility in an aggregate principal amount of $600.0 million with a five-year maturity. Pentair Finance has received commitments from such financial institutions, and expects to close an amendment to the loan agreement in June 2022, to increase the term loan facility by $400.0 million to an aggregate principal amount of $1.0 billion. However, we cannot provide any assurance that we will close such amendment to the loan agreement or with respect to the definitive terms and documentation thereof. We refer to the loan agreement, as we expect it to be amended, in this prospectus supplement as the “term loan facility”. Pentair Finance and Pentair intend to borrow the full $1.0 billion aggregate principal amount available under the term loan facility to finance a portion of the purchase price in the Manitowoc Ice acquisition and to pay related fees and expenses. The term loan facility is guaranteed by Pentair. The aggregate principal amount of the commitments under the term loan facility replace a corresponding amount of the commitments in respect of the bridge facility in accordance with the terms of the bridge facility commitment letter. As a result, upon the closing of the amendment to the loan agreement, there will be $600.0 million in bridge facility commitments remaining under the bridge

facility commitment letter. The remaining bridge facility commitments under the bridge facility commitment letter will be further reduced on a dollar-for-dollar basis by the net proceeds from this offering.

The availability of loans under the term loan facility is subject to the satisfaction or waiver of certain conditions that are substantially consistent with the conditions to the funding of the bridge facility, including (i) the closing of the Manitowoc Ice acquisition substantially concurrently with the funding of such loans, (ii) the absence of a material adverse effect with respect to Manitowoc Ice since March 2, 2022, (iii) the truth and accuracy in all material respects of certain representations and warranties, (iv) the receipt of certain certificates, and (v) the receipt of certain financial statements. Loans made under the term loan facility will rank equally in right of payment with the notes. We refer to the funding of the term loan facility in this prospectus supplement as the “term loan financing”.

We define free cash flow as net cash provided by operating activities less capital expenditures plus proceeds from sale of property and equipment. Free cash flow is a non-GAAP financial measure that we use to assess our cash flow performance. We believe free cash flow is an important measure of liquidity because it provides us and our investors a measurement of cash generated from operations that is available to pay dividends, repurchase shares and repay debt. In addition, free cash flow is used as a criterion to measure and pay annual incentive compensation. Our measure of free cash flow may not be comparable to similarly titled measures reported by other companies.

RISK FACTORS

Before you invest in the notes, you should consider the factors set forth below, together with all of the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, including the risk factors set forth under the heading “Risk Factors” in our most recent Annual Report on Form 10-K for the year ended December 31, 2021 and in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2022, as well as any of our subsequently filed quarterly or current reports. If any of the following risks and uncertainties develops into actual events, our business, financial condition, results of operations or cash flows could be materially adversely affected. In that case, the trading price of the notes could decline and you may lose all or part of your investment.

Risks Relating to the Manitowoc Ice Acquisition

We may not realize the anticipated benefits of the Manitowoc Ice acquisition and any benefit may take longer to realize than we expect.

The Manitowoc Ice acquisition will involve the integration of Manitowoc Ice’s operations with our existing operations, and there are uncertainties inherent in such an integration. We will be required to devote significant management attention and resources to integrating Manitowoc Ice’s operations. Delays or unexpected difficulties in the integration process could adversely affect our business, financial results and financial condition. Even if we are able to integrate Manitowoc Ice’s operations successfully, this integration may not result in the realization of the full benefits of revenue synergies, cost savings and operational efficiencies that we expect or the achievement of these benefits within a reasonable period of time or at all.

We could be subject to new risks, known and unknown, relating to the Manitowoc Ice acquisition.

We may experience risks, losses and damages associated with the Manitowoc Ice acquisition. The risks we could face include the following:

•

the Manitowoc Ice acquisition may lead to the incurrence of costs to review, upgrade and integrate Manitowoc Ice’s systems with our compliance and reporting systems, including our systems of internal control over financial reporting. The process of integrating Manitowoc Ice into our internal control over financial reporting could require significant time and effort from our management and other personnel and could increase our compliance costs; and

•

the Manitowoc Ice acquisition involves the inherent risk of liabilities, and these liabilities may prove more costly or produce more adverse effects than we anticipate, such as actual or potential litigation and regulatory matters. In addition, in the course of the due diligence review of Manitowoc Ice, we may not have discovered, or may have been unable to quantify, undisclosed liabilities of Manitowoc Ice, and we may not be indemnified or have insurance for any of these liabilities. Any such liabilities could have an adverse effect on our business, results of operations, financial condition and cash flows following the completion of the Manitowoc Ice acquisition.

Any of these risks associated with the Manitowoc Ice acquisition could have a material adverse impact on our business, results of operations and financial condition.

Increased leverage may harm our financial condition and results of operations.

As of March 31, 2022, we had $1,102.6 million of total debt on a consolidated basis. We expect our indebtedness to increase materially in connection with our acquisition of Manitowoc Ice. We intend to fund the Manitowoc Ice acquisition with the net proceeds of this offering and the term loan financing, together with cash on hand and/or borrowings under our revolving credit facility, and, if necessary, borrowings under the bridge facility for an aggregate amount of approximately $1.6 billion of new indebtedness in connection with the Manitowoc Ice acquisition. We and our subsidiaries may incur additional indebtedness in the future and, subject to limitations on the amount of secured indebtedness we may incur without securing the notes and other outstanding debt securities as described under “Description of Notes,” the indenture that will govern the notes will not restrict us from incurring indebtedness in the future. This increase and any future

S-11

TABLE OF CONTENTS

increase in our level of indebtedness will have several important effects on our future operations, including, without limitation:

•

we will have additional cash requirements in order to support the payment of interest on our outstanding indebtedness;

•

increases in our outstanding indebtedness and leverage may increase our vulnerability to adverse changes in general economic and industry conditions, as well as to competitive pressure;

•

our ability to obtain additional financing for working capital, capital expenditures, general corporate and other purposes may be reduced;

•

our flexibility in planning for, or reacting to, changes in our business and our industry may be reduced; and

•

our flexibility to make acquisitions and develop technology may be limited.

Our ability to make payments of principal and interest on our indebtedness, including the notes, depends upon our future performance, which will be subject to general economic conditions and financial, business and other factors affecting our consolidated operations, many of which are beyond our control. If we are unable to generate sufficient cash flow from operations in the future to service our debt and meet our other cash requirements, we may be required, among other things:

•

to seek additional financing in the debt or equity markets;

•

to refinance or restructure all or a portion of our indebtedness, including the notes;

•

to sell selected assets or businesses; or

•

to reduce or delay planned capital or operating expenditures.

Such measures might not be sufficient to enable us to service our debt and meet our other cash requirements, including the notes. In addition, any such financing, refinancing or sale of assets might not be available at all or on economically favorable terms.

Risks Relating to the Notes

Pentair Finance and Pentair are responsible for indebtedness other than the notes and guarantees offered hereby.

Pentair Finance and Pentair are responsible for indebtedness other than the notes offered hereby. Pentair Finance is a borrower under its existing term loan facility, under which there were $200.0 million of borrowings outstanding as of March 31, 2022, and revolving credit facility, under which there were $395.0 million of borrowings outstanding and borrowing capacity of $505.0 million available as of March 31, 2022. In connection with the Manitowoc Ice acquisition, Pentair Finance intends to borrow $1.0 billion on the term loan facility. As of March 31, 2022, Pentair Finance also had outstanding $507.6 million aggregate principal amount of existing senior notes. In addition, Pentair is a guarantor of the existing term loan facility and revolving credit facility, the guarantor of payment of principal and interest on the existing outstanding senior notes and will guarantee borrowings under the term loan facility (and borrowings, if any, under the bridge facility) in connection with the Manitowoc Ice acquisition.

We cannot assure you that an active trading market for the notes will develop.

The notes are a new issue of securities with no established trading market and Pentair Finance does not intend to list them on any securities exchange or automated quotation system. We have been informed by the underwriters that they intend to make a market in the notes after the offering is completed. However, the underwriters have no obligation to do so and may cease their market making at any time. In addition, such market-making activity will be subject to limits imposed by the Securities Act of 1933, as amended (the “Securities Act”) and the Exchange Act. Additionally, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for fixed income securities and by changes in our financial performance or prospects or in the prospects for

S-12

TABLE OF CONTENTS

companies in our industries generally. As a result, you cannot be sure that an active trading market for the notes will develop. If no active trading market develops, you may not be able to resell your notes at their fair market value or at all.

The notes do not restrict our ability to incur additional debt, repurchase our securities or take other actions that could adversely affect holders of the notes. In addition, the restrictions in the indenture on our ability to grant liens and enter into sale and lease-back transactions are subject to significant exceptions.

We are not restricted under the terms of the notes from incurring additional debt or repurchasing our securities. The terms of the indenture will limit our ability to secure additional debt and enter into sale and lease-back transactions without securing the notes and other outstanding debt securities under the indenture. However, these limitations will be subject to numerous exceptions, which, among other things, permit us to engage in certain permitted securitization transactions and grant liens securing certain indebtedness. The notes are unsecured and are effectively subordinated to any existing or future secured indebtedness of Pentair Finance and Pentair.

In addition, the limited covenants applicable to the notes do not require us to achieve or maintain any minimum financial results relating to our financial position or results of operations or debt ratings. Our ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the notes could have the effect of diminishing our ability to make payments on the notes when due.

Each of Pentair Finance and Pentair will depend on its respective subsidiaries for funds to meet its obligations under the notes and guarantees. The notes and the guarantees will be effectively subordinated to all existing and future liabilities of Pentair’s and Pentair Finance’s subsidiaries.

Pentair is a holding company established to own directly and indirectly substantially all of our operating and other subsidiaries. Pentair Finance is a holding company formed to own directly and indirectly substantially all of our operating and other subsidiaries and to issue debt securities, including the notes, or make other borrowings. Pentair’s principal source of cash flow, including cash flow to make payments on the notes pursuant to the guarantees, is dividends from Pentair Finance. Pentair Finance’s principal source of cash flow is interest income from our subsidiaries. None of the subsidiaries of Pentair Finance or Pentair (other than Pentair Finance) is under any direct obligation to pay or otherwise fund amounts due on the notes or the guarantees, whether in the form of dividends, distributions, loans or other payments. In addition, there may be statutory and regulatory limitations on the payment of dividends from certain subsidiaries of Pentair Finance or Pentair. If such subsidiaries are unable to transfer funds to Pentair Finance or Pentair and sufficient cash or liquidity is not otherwise available, Pentair Finance or Pentair may not be able to make principal and interest payments on their outstanding debt, including the notes or the guarantees.

In addition, Pentair Finance and Pentair’s right to receive any assets of any of their respective subsidiaries upon their bankruptcy, liquidation or reorganization, and therefore the right of the holders of the notes to participate in those assets under the terms of the notes or pursuant to the guarantees, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors. As of March 31, 2022, the aggregate outstanding liabilities of Pentair Finance’s subsidiaries to which the notes and the guarantees were structurally subordinated were $1,308.3 million. Even if Pentair Finance or Pentair were a creditor of the other Pentair subsidiaries, its right as a creditor would be subordinate to any security interest in the assets of such subsidiaries and any indebtedness of such subsidiaries senior to that held by it.

Pentair Finance may not be able to repurchase the notes upon a change of control triggering event.

Upon the occurrence of a change of control event that constitutes a “Change of Control Triggering Event” as described under “Description of Notes — Change of Control,” each holder of the notes will have the right to require Pentair Finance to repurchase all or any part of such holder’s notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. Additionally, upon the occurrence of certain events that would constitute a “Change of Control Triggering Event” each holder of other senior notes issued by Pentair Finance will have the right to require Pentair Finance to repurchase all or any part of such holder’s notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. If we experience

S-13

TABLE OF CONTENTS

such an event, there can be no assurance that Pentair Finance would have sufficient financial resources available to satisfy its obligation to repurchase the notes and the other senior notes. Pentair Finance’s failure to repurchase the notes as required under the respective indentures governing the notes and the other senior notes would result in a default under the indenture, which could have material adverse consequences for us and the holders of the notes. See “Description of Notes — Change of Control.” Additionally, certain events that would constitute a “Change of Control Triggering Event” would constitute an event of default under the revolving credit facility and term loan facility that would, if it should occur, permit the lenders to accelerate the debt outstanding under such revolving credit facility and term loan facility and that, in turn, would cause an event of default under the indenture that will govern the notes.

Our ability to complete the Manitowoc Ice acquisition is subject to various conditions, certain of which are beyond our control. The Purchase Agreement contains certain termination provisions permitting each party thereto to terminate the Purchase Agreement under certain circumstances.

If the consummation of the Manitowoc Ice acquisition does not occur on or prior to the outside date, Pentair Finance notifies the trustee and the holders of the notes that in its reasonable judgment the Manitowoc Ice acquisition will not be consummated on or prior to the outside date or the Purchase Agreement has been terminated without the consummation of the Manitowoc Ice acquisition, then Pentair Finance will be required to redeem all of the notes then outstanding on the Special Mandatory Redemption Date at a special mandatory redemption price equal to 101% of the principal amount of the notes then outstanding plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date. See “Description of Notes — Special Mandatory Redemption.” If we redeem the notes pursuant to the special mandatory redemption, you may not obtain the return that you expected on your investment in the special mandatory redemption notes. Whether or not the special mandatory redemption is ultimately triggered, it may adversely affect trading prices for the notes prior to the Special Mandatory Redemption Date.

You will have no rights under the special mandatory redemption provisions if the Manitowoc Ice acquisition closes, nor will you have any right to require us to repurchase your notes if, between the closing of this offering and the consummation of the Manitowoc Ice acquisition, we experience any changes (including any material adverse changes) in our business or financial condition, or if the terms of the Purchase Agreement change, including in material respects.

We may be unable to redeem any or all of the notes in the event of a special mandatory redemption.

We are not obligated to place the proceeds of the offering of any notes in escrow prior to the consummation of the Manitowoc Ice acquisition or to provide a security interest in those proceeds, and there are no other restrictions on our use of these proceeds during this time. Pending such uses, we may invest the net proceeds from this offering temporarily in investment grade securities, money market funds, bank deposit accounts or similar short-term investments, or use such net proceeds to repay outstanding borrowings under our revolving credit facility. Accordingly, we will need to fund any special mandatory redemption of the notes using proceeds that we have voluntarily retained and from other sources of liquidity, including borrowings under our revolving credit facility. In the event of a special mandatory redemption, we may not have sufficient funds to redeem any or all of the notes, which would constitute an event of default under the indenture and could result in defaults under our other debt agreements and have material adverse consequences for us and the holders of the notes.

It may not be possible to enforce U.S. judgments in Ireland.

It may not be possible to enforce court judgments obtained in the United States against Pentair (or its directors or officers) in Ireland, whether based on the civil liability provisions of the U.S. federal or state securities laws or otherwise. We have been advised that the United States currently does not have a treaty with Ireland providing for the reciprocal recognition and enforcement of judgments in civil matters. Therefore,

S-14

TABLE OF CONTENTS

a final judgment for the payment of money rendered by any U.S. federal or state court based on civil liability, whether or not based solely on U.S. federal or state securities laws, would be enforced to the extent described under “Enforcement of Civil Liabilities — Ireland” in the accompanying prospectus but would not be automatically enforceable in Ireland. In addition, Irish courts would be unlikely to entertain actions against us or those persons based on those laws.

Irish laws differ from the laws in effect in the United States and may afford less protection to holders of our securities.

As an Irish company, Pentair is governed by Irish company law (principally, the Irish Companies Act 2014 (as amended) (the “Companies Act 2014”)). Irish company law differs in some material respects from laws generally applicable to U.S. corporations and shareholders, including, among others, differences relating to interested director and officer transactions and shareholder lawsuits. Likewise, the duties of directors and officers of an Irish company generally are owed to the company only. Shareholders of Irish companies generally do not have a personal right of action against directors or officers of the company and may exercise such rights of action on behalf of the company only in limited circumstances. Accordingly, holders of Pentair’s securities may have more difficulty protecting their interests than would holders of securities of a corporation incorporated in a jurisdiction of the United States.

If Pentair is unable to pay its debts, an examiner may be appointed under Irish law to oversee its operations.

If Pentair is unable, or likely to be unable, to pay its debts, an examiner may be appointed to oversee its operations and to facilitate its survival and the whole or any part of its business by formulating proposals for a compromise or scheme of arrangement. If an examiner is appointed to Pentair, a protection period, not exceeding 100 days, will be imposed so that the examiner can formulate and implement its proposals for a compromise or scheme of arrangement. During the protection period, any enforcement action by a creditor is prohibited. In addition, any company to which an examiner has been appointed would be prohibited from paying any debts existing at the time of the presentation of the petition to appoint an examiner. The appointment of an examiner may restrict the ability of Pentair to make timely payments under its guarantee and holders may be unable to enforce their rights under the guarantee. During the course of examinership, holders’ rights under the Pentair guarantee may be affected by the examiner’s exercise of its powers, for example, repudiate a restriction or prohibition on further borrowings or the creation of a security interest.

Further, a scheme of arrangement may be approved involving the writing down of the debt due by Pentair to the holders of the notes irrespective of their views. In the event that a scheme of arrangement is not approved and Pentair subsequently goes into liquidation, the examiner’s remuneration and expenses (including certain borrowings incurred by the examiner on behalf of Pentair and approved by the Irish High Court) and the claims of certain other creditors (including the Irish Revenue Commissioners for certain unpaid taxes) will take priority over the amounts due by Pentair to the holders of the notes in accordance with the Companies Act 2014 and, where applicable, the Rules of the Superior Courts of Ireland.

The validity and enforceability of guarantees by Pentair may be subject to certain limitations.

Guarantees by Pentair may be subject to review under Irish law in the following circumstances:

•

if Pentair becomes the subject of liquidation proceedings within six months (or two years if such guarantee is given in favor of anyone who is, in relation to Pentair, a connected person) of issuing a guarantee and is made the subject of an application by the liquidator, on behalf of Pentair, to the Irish courts to void such guarantee on the grounds that the issuance of the guarantee constituted an unfair preference in accordance with Section 604 of the Companies Act 2014 over other creditors at a time when Pentair was insolvent. In order for any appointed liquidator to be successful in such an application, it would be necessary to establish that the “dominant intention” of Pentair was to prefer one creditor over another (to the detriment of other creditors);

•

if Pentair were wound up, then on the application of a liquidator or creditor (pursuant to Section 608 of the Companies Act 2014), if it can be shown that such guarantee or any payments made thereunder had the “effect” of perpetrating a fraud on Pentair, its creditors or shareholders, the Irish courts can order a return of payments made by Pentair under such guarantee. For the purposes of

S-15

TABLE OF CONTENTS

Section 608 of the Companies Act 2014, it is not necessary to establish that Pentair intended to defraud their creditors as it is sufficient if it can be shown that the transaction had the “effect” of perpetrating a fraud;

•

if the giving of such guarantee by Pentair constitutes the giving of unlawful financial assistance for the purpose of an acquisition (by subscription, purchase, exchange or otherwise) made or to be made by any person of any shares in Pentair;

•

if such guarantee is challenged on the grounds that it exceeded, where applicable, the corporate objects of Pentair or that there was no corporate benefit to Pentair in entering into such guarantee; or

•

Pentair having become insolvent, or deemed likely to become insolvent, is made the subject of court protection under the examinership procedure (see further below) and the court approves a scheme for the compromise of debts of Pentair.

Under the laws of Ireland, a guarantee may only be issued where the entity issuing the guarantee receives sufficient commercial benefit for doing so. If there is insufficient commercial benefit, the beneficiary of the guarantee may not be able to rely on the authority of the directors of that entity to grant the guarantee and accordingly a court may set aside the guarantee at the request of the entity’s shareholders or a liquidator. The board of directors of Pentair has passed a resolution that the entry into the guarantee is in Pentair’s best interests and for its corporate benefit. However, no assurance can be given that a court would agree with its conclusion in this regard. The notes may only be guaranteed by Pentair to the extent that it would not result in such guarantee constituting the giving of unlawful financial assistance within the meaning of Section 82 of the Companies Act 2014. In addition, in an insolvency of an Irish company, the claims of certain preferential creditors (including the Irish Revenue Commissioners for certain unpaid taxes, and certain employee claims) will rank in priority to claims of unsecured creditors. If Pentair becomes subject to an insolvency proceeding and Pentair has obligations to creditors that are treated under Irish law as creditors that are senior relative to the holders of the notes, the holders of the notes may suffer losses as a result of their subordinated status during such insolvency proceeding.

If the giving of any note guarantee by Pentair constituted the giving of unlawful financial assistance for the purpose of an acquisition (by subscription, purchase, exchange or otherwise) made or to be made by any person of any shares in Pentair, then such note guarantee would be voidable by Pentair (or any insolvency officer of Pentair) against any person (including the holders of the notes) who had notice of the facts which constituted such breach of law.

Luxembourg laws differ from the laws in effect in the United States and may afford less protection to holders of our securities, including the notes.

Pentair Finance is organized under the laws of Luxembourg. It may not be possible to enforce court judgments obtained in the United States against us or against Pentair Finance in Luxembourg based on the civil liability provisions of the U.S. federal or state securities laws. In addition, there is some uncertainty as to whether the courts of Luxembourg would recognize or enforce judgments of U.S. courts obtained against us or our directors or officers or the directors or officers of Pentair Finance based on the civil liability provisions of the U.S. federal or state securities laws or hear actions against us or those persons based on those laws. We have been advised that the United States currently does not have a treaty with Luxembourg providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. Therefore, a final judgment for the payment of money rendered by any U.S. federal or state court based on civil liability, whether or not based solely on U.S. federal or state securities laws, would not automatically be enforceable in Luxembourg.

Due to the nature of Luxembourg’s insolvency laws, the ability of the holders of the notes to protect their interests may be more limited than would be the case under U.S. bankruptcy laws. In the event of a winding up of Pentair Finance, the notes will be paid after payment of all secured debts, the cost of liquidation and certain debts of Pentair Finance that are entitled to priority under Luxembourg law. Such preferential debts include the following:

•

money owed to Luxembourg tax authorities, for example, in respect of income tax deducted at the source;

S-16

TABLE OF CONTENTS

•

value-added tax and certain other taxes and duties owed to Luxembourg Customs and Excise;

•

social security contributions; and

•

remuneration owed to employees.

If the bankruptcy administrator can show that “preference” has been given to any person by defrauding rights of creditors generally, regardless of when the transaction giving fraudulent preference to a party occurred, or if certain “abnormal” transactions have been effected during a relevant suspect period of six months plus ten days prior to the date of bankruptcy, a court has the power, among other things, to void the preferential or abnormal transaction. This provision of Luxembourg insolvency law may affect transactions entered into or payments made by Pentair Finance during the period before liquidation or administration.

Pentair and Pentair Finance 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 were required 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 should apply as of January 1, 2022). As adopted, ATAD introduces a new framework that limits the deduction of interest and other deductible payments and charges for Luxembourg companies subject to corporate income tax, including Pentair Finance. Under ATAD, if Pentair Finance is in an exceeding borrowing cost position as determined under ATAD or if any of the anti-hybrid rules under ATAD 2 apply, which could occur if the notes issued by Pentair Finance qualify for tax purposes as hybrid financial instruments, a portion of the interest accrued on the notes may not be tax deductible. As a result, these rules could increase Pentair Finance’s taxable base and may result in adverse financial impacts to Pentair Finance.

Ireland has implemented the interest limitation rules, but as Pentair is not resident for tax purposes in Ireland, the interest limitation rules should have no effect on it.

Our credit ratings may not reflect all risks of your investment in the notes.

The credit ratings assigned to the notes are limited in scope, and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. There can be no assurance that such 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 the applicable rating agencies, if, in such rating agency’s judgment, circumstances so warrant. 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 our credit ratings, including any announcement that our ratings are under further review for a downgrade, could affect the market value of the notes and increase our corporate borrowing costs. Furthermore, the ratings of the notes may not reflect the potential impact of all risks related to structure and other factors on any trading market for, or market price of, the notes.

Redemption of the notes prior to their maturity may adversely affect your return on the notes.

Pentair Finance has the right, or, in certain instances, may be required, to redeem some or all of the notes prior to maturity, as described under “Description of Notes — Optional Redemption” and “Description of Notes — Special Mandatory Redemption.” Pentair Finance 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 redeemed.

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $ million after deducting the underwriting discount and estimated offering expenses.

We intend to use the net proceeds of this offering and the term loan financing, together with cash on hand and/or borrowings under our revolving credit facility, and, if necessary, borrowings under the bridge facility to finance the Manitowoc Ice acquisition for approximately $1.6 billion and to pay related fees and expenses. We intend to use any remaining proceeds for general corporate purposes. Pending such uses, we may invest the net proceeds from this offering temporarily in investment grade securities, money market funds, bank deposit accounts or similar short-term investments, or use such net proceeds to repay outstanding borrowings under our revolving credit facility. See “Capitalization.”

This offering is not contingent upon, and may be settled before, the consummation of the Manitowoc Ice acquisition. However, in the event that the consummation of the Manitowoc Ice acquisition does not occur on or prior to the outside date, Pentair Finance notifies the trustee and the holders of the notes that in its reasonable judgment the Manitowoc Ice acquisition will not be consummated on or prior to the outside date or the Purchase Agreement has been terminated without the consummation of the Manitowoc Ice acquisition, then Pentair Finance will be required to redeem all outstanding notes offered hereby. See “Description of Notes — Special Mandatory Redemption.”

DESCRIPTION OF NOTES

The notes will be issued under the indenture, dated as of September 16, 2015, among Pentair Finance S.à r.l., as issuer, Pentair plc, as guarantor, and U.S. Bank Trust Company, National Association (as successor to U.S. Bank National Association), as trustee (the “Trustee”), as supplemented by the seventh supplemental indenture, dated as of June 22, 2020, and as further supplemented by a supplemental indenture to be dated as of the closing date of this offering (such indenture, as so supplemented by the supplemental indenture, the “Indenture”). The Indenture is subject to, and is governed by, the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). You are urged to read the form of notes and the Indenture because they, not the summaries below, define your rights. You may obtain a copy of the Indenture as described under “Incorporation by Reference.”

References to the “Issuer” or “Pentair Finance” are to Pentair Finance S.à r.l., the issuer of the notes, and references to Pentair Finance in this description do not, unless the context otherwise indicates, include any of its subsidiaries. References to the “Guarantor” or “Pentair” in this description refer to Pentair plc, not including its subsidiaries. Capitalized terms used but not defined in this section have the respective meanings set forth in the Indenture.

The following description of certain material terms of the notes offered hereby does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the Indenture, including definitions therein of certain terms. This description adds information to the description of the general terms and provisions of the debt securities set forth in “Description of Debt Securities and Guarantees of Debt Securities” in the accompanying prospectus, and the notes are a series of debt securities. To the extent this summary differs from the summary in the accompanying prospectus, you should rely on the description in this prospectus supplement.

General

The Issuer will issue $ million initial aggregate principal amount of the notes due 20 , which will mature on , 20 (the “notes”).

The notes will be issuable in whole in the registered form of one or more global securities, and the depository for such global securities will be The Depository Trust Company, New York, New York. The notes will be issuable in denominations of $2,000 or any integral multiple of $1,000 in excess thereof.

Except as provided below, the notes will not be subject to redemption, repurchase or repayment at the option of any holder thereof, upon the occurrence of any particular circumstances or otherwise. The notes will not have the benefit of any sinking fund. The notes are not convertible into shares of common stock or other securities of the Issuer or the Guarantor.

Ranking

The notes will be unsecured and unsubordinated obligations and will rank equally in right of payment with all of the Issuer’s other unsecured and unsubordinated debt. The guarantee will be an unsecured and unsubordinated obligation and will rank equally in right of payment with the Guarantor’s existing and future unsecured and unsubordinated indebtedness. As described under “— Guarantee,” the notes will be fully and unconditionally guaranteed by the Guarantor. The notes will not be guaranteed by, and therefore will not constitute obligations of, the Issuer’s subsidiaries or the Guarantor’s subsidiaries other than the Issuer. Creditors of the Issuer’s subsidiaries or the Guarantor’s other subsidiaries are entitled to a claim on the assets of those subsidiaries. Consequently, in the event of a liquidation or reorganization of such a subsidiary, creditors of such subsidiary are likely to be paid in full before any distribution is made to the Issuer or the Guarantor, except to the extent that the Issuer or the Guarantor, as applicable, is itself recognized as a creditor of that subsidiary, in which case the Issuer’s or the Guarantor’s claims, as applicable, would still be subordinate to any security interests in the assets of the subsidiary and any debt of the subsidiary senior to that held by the Issuer or the Guarantor, as applicable. As of March 31, 2022, Pentair’s subsidiaries (other than Pentair Finance) had approximately $1,308.3 million of liabilities, including indebtedness, outstanding.

S-21

TABLE OF CONTENTS

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 the Issuer may authorize from time to time. The Indenture also does not limit the amount of other unsecured indebtedness or securities that the Issuer may issue.

As of March 31, 2022, Pentair Finance had $1,102.6 million of indebtedness outstanding, none of which was secured. As of such date after giving effect to this offering and the use of the net proceeds thereof as described under “Use of Proceeds,” Pentair Finance would have had $ million of indebtedness outstanding. As of March 31, 2022, Pentair had no indebtedness other than its guarantees of indebtedness of Pentair Finance.

Interest

The notes will bear interest at a rate of % per year. The date from which interest will accrue on the notes will be , 2022, or the most recent interest payment date to which interest has been paid or provided for. The interest payment dates for the notes will be and of each year, beginning on , 2022. Interest will be payable on each interest payment date to the holders of record at the close of business on the or immediately prior to the interest payment date; however, interest payable at maturity will be paid to the person to whom principal is payable. Interest on the notes will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

If any interest payment date on the notes would otherwise be a day that is not a Business Day (as defined below), that interest payment date will be postponed to the next date that is a Business Day, and no interest on such payment will accrue in respect of the delay. If the maturity date or any date of redemption of the notes falls on a day that is not a Business Day, the related payment of principal and interest 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.

Guarantee

The Guarantor will fully and unconditionally guarantee the due and punctual payment of the principal of, premium, if any, and interest and any Additional Amounts, if any, on the notes, when and as the same shall become due and payable, whether at maturity, by acceleration, upon redemption or otherwise. The guarantee provides that in the event of a default in payment on a note, the holder of the note may institute legal proceedings directly against the Guarantor to enforce the guarantee without first proceeding against the Issuer.

If the Issuer exercises its covenant defeasance right, the Issuer and the Guarantor will no longer be subject to the covenants described under “— Limitation on Mergers and Other Transactions,” “— Limitation on Liens,” “— Limitation on Sale and Lease-Back Transactions” and “— Change of Control” and the covenants described in the accompanying prospectus under “Description of Debt Securities and Guarantees of Debt Securities — Certain Covenants — Reports by Pentair Finance.” In addition, the Events of Default described under clauses (3), (4) (as it relates to the covenants described under “— Certain Covenants”), (5), (8), (9) and (10) in the first paragraph under “— Events of Default” will no longer apply to the notes.

Additional Notes

The Issuer may, without the consent of the then existing holders of the notes, “re-open” the notes and issue additional notes, which additional notes will have the same terms as the 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 existing notes for U.S. federal income tax purposes, such additional notes will be issued with a separate CUSIP code from the existing notes. Additional notes issued in this manner will form a single series with the notes offered hereby.

Optional Redemption

Prior to the Par Call Date (defined below), the Issuer may redeem the notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

•

(a) the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed discounted to the redemption date (assuming the notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points less (b) interest accrued to the date of redemption, and

•

100% of the principal amount of the notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after the Par Call Date, the Issuer may redeem the notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

For purposes of the foregoing discussion of optional redemption, the following definitions are applicable:

“Par Call Date” means , 20 (the date that is prior to the maturity date).

“Treasury Rate” means, with respect to the redemption date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the Par Call Date on a straight-line basis (using

S-28

TABLE OF CONTENTS

the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third Business Day preceding the redemption date, H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 but not more than 60 days before the redemption date to each holder of the notes to be redeemed.

In the case of a partial redemption, selection of the notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes are held by The Depository Trust Company (the “DTC”) or another depositary, the redemption of the notes shall be done in accordance with the policies and procedures of the depositary.

Unless the Issuer defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

In addition, the Guarantor, the Issuer and their respective affiliates may purchase notes from the holders thereof from time to time, either in the open market at prevailing prices or in private transactions at negotiated prices. Any notes purchased by the Guarantor, the Issuer or any of their respective affiliates may, at the purchaser’s discretion, be held, resold or canceled.

Special Mandatory Redemption

The completion of this offering is not contingent on, and may be settled before, the consummation of the Manitowoc Ice acquisition.

If (a) the consummation of the Manitowoc Ice acquisition does not occur on or prior to January 14, 2023 (or such later date on or before April 14, 2023 as extended by the parties to the Purchase Agreement pursuant to the terms and conditions set forth therein, the “outside date”), (b) the Issuer notifies the Trustee and the holders of the notes that in its reasonable judgment the Manitowoc Ice acquisition will not be consummated on or prior to the outside date or (c) the Purchase Agreement has been terminated without the consummation of the Manitowoc Ice acquisition (each of (a), (b) and (c), a “Special Mandatory

Redemption Trigger”), the Issuer will be required to redeem all of the notes then outstanding on the date of the special mandatory redemption (such redemption, the “Special Mandatory Redemption”) at a redemption price equal to 101% of the principal amount of the notes then outstanding, plus accrued and unpaid interest, if any, to, but not including, the Special Mandatory Redemption Date (as defined below) (the “Special Mandatory Redemption Price”).

In the event that the Issuer becomes obligated to redeem the notes pursuant to the Special Mandatory Redemption, the Issuer will promptly, and in any event not more than two Business Days after the date on which a Special Mandatory Redemption Trigger occurred, deliver notice to the Trustee and the holders of the notes of the Special Mandatory Redemption and the date upon which the notes will be redeemed (the “Special Mandatory Redemption Date”, which date shall be on or about the tenth Business Day following the date of such notice (or such other minimum period as may be required by DTC)) together with a notice of a Special Mandatory Redemption for the Trustee to deliver to each registered holder of notes to be redeemed. At the Issuer’s written request, given at least one Business Day before such notice is to be sent, the Trustee will then promptly mail or electronically deliver (or otherwise transmit in accordance with the depositary’s procedures), such notice of Special Mandatory Redemption to each registered holder of the notes to be redeemed. Unless the Issuer defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the notes to be redeemed.

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

There is no escrow account for or security interest in the proceeds of this offering for the benefit of holders of the notes in the event of a Special Mandatory Redemption Trigger.

Payment of Additional Amounts and Redemption upon Changes in Withholding Taxes

The provisions described in “Description of Debt Securities and Guarantees of Debt Securities — Payment of Additional Amounts” and “— Redemption upon Changes in Withholding Taxes” in the accompanying prospectus will be applicable to the notes.

Change of Control

If a Change of Control Triggering Event (as defined below) with respect to the notes occurs, unless the Issuer has exercised its option to redeem the notes, it shall be required to make an offer (a “Change of Control Offer”) to each holder of the notes to repurchase, at the holder’s election, all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that holder’s notes on the terms set forth in the Indenture. In a Change of Control Offer, the Issuer shall be required to offer payment in cash equal to 101% of the principal amount of notes to be repurchased, plus accrued and unpaid interest, if any, on the notes to be repurchased to, but excluding, the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event with respect to the notes or, at the Issuer’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be sent to the Trustee and the holders of the notes describing in reasonable detail the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the notes on the date specified in the notice, which date shall, except as described in the immediately following sentence, be no earlier than 30 and no later than 60 days from the date such notice is sent (or, in the case of a notice prior to the consummation of the Change of Control Triggering Event, no earlier than 30 nor later than 60 days from the Change of Control Triggering Event) other than as may be required by law (a “Change of Control Payment Date”). The notice shall, if sent prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

If the Change of Control Payment Date 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

S-30

TABLE OF CONTENTS

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.

Any exercise by a holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of Control Offer may be accepted for less than the entire principal amount of a note, but in that event the principal amount of such note remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof.

The Issuer shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and the third party purchases all notes properly tendered and not withdrawn under its offer. In addition, the Issuer shall 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 upon a Change of Control Triggering Event.

Notwithstanding the foregoing, the Issuer and the Guarantor will comply 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. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the notes, neither the Issuer nor the Guarantor will be deemed to have breached its obligations under the Change of Control Offer provisions of the notes by virtue of its compliance with such securities laws or regulations.

For purposes of the Change of Control Offer provisions of the notes, the following terms are applicable:

“Change of Control” means the occurrence on or after the Issue Date of any of the following: (1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the assets of Pentair and its subsidiaries, taken as a whole, to any person, other than Pentair or a direct or indirect wholly-owned subsidiary of Pentair; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any person becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of Pentair’s outstanding Voting Stock or other Voting Stock into which Pentair’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; (3) Pentair consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, Pentair, in any such event pursuant to a transaction in which any of Pentair’s outstanding Voting Stock or the Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of Pentair’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, at least a majority of the Voting Stock of the surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; or (4) the approval by the holders of Pentair’s Voting Stock of a plan for Pentair’s liquidation or dissolution. Notwithstanding the foregoing, a transaction shall not be deemed to involve a Change of Control under clause (1), (2) or (4) above if (i) Pentair becomes a direct or indirect wholly-owned subsidiary of a holding company or a holding company becomes the successor to Pentair under the Indenture pursuant to a transaction that is permitted under the Indenture and (ii) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction (or a series of related transactions) are the same or substantially the same (and hold in the same or substantially the same proportions) as the holders of Pentair’s Voting Stock immediately prior to that transaction. The term “person,” as used in this definition, means any Person and any two or more Persons as provided in Section 13(d)(3) of the Exchange Act.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event; provided, however, that a Change of Control Triggering Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a Change of Control if the Rating Agency or Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or

S-31

TABLE OF CONTENTS

in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the purported Change of Control Triggering Event). Unless at least two of the three Rating Agencies are providing a rating for the notes at the commencement of any period referred to in the definition of “Rating Event” below, a Rating Event will be deemed to have occurred during such period. 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.

“Fitch” means Fitch Inc., and its successors.

“Investment Grade Rating,” means a rating equal to or higher than BBB– (or the equivalent) by Fitch, Baa3 (or the equivalent) by Moody’s and BBB– (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by the Issuer.

“Moody’s” means Moody’s Investors Service, Inc., and its successors.

“Rating Agencies” means (1) each of Fitch, Moody’s and S&P; and (2) if any of Fitch, Moody’s or S&P ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of the Issuer’s control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) under the Exchange Act, selected by the Issuer (as certified by a resolution of the Issuer’s Board of Managers) as a replacement agency for Fitch, Moody’s or S&P, or all of them, as the case may be.

“Rating Event” means the rating on the notes is lowered by at least two of the three Rating Agencies and the notes are rated below an Investment Grade Rating by at least two of the three Rating Agencies on any day during the period (which period shall be extended for so long as the rating of the notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) commencing on the date of Pentair’s first public notice of the occurrence of a Change of Control or Pentair’s intention to effect a Change of Control and ending 60 days following consummation or abandonment of such Change of Control.

“S&P” means S&P Global Ratings, a division of S&P Global Inc., and its successors.

“Voting Stock” means, with respect to any specified “Person” as of any date, the capital stock of such Person that is at the time entitled to vote generally in the election of the board of directors or managers of such Person.

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 assets of Pentair 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 the Issuer offer to repurchase the notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of Pentair’s and its subsidiaries’ assets taken as a whole to another “person” (as such term is used in Section 13(d)(3) of the Exchange Act) may be uncertain.

INCOME TAX CONSIDERATIONS

Luxembourg

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. Prospective investors in the 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), minimum net wealth tax (impôt sur la fortune minimum) as well as other duties, levies or taxes. Corporate income tax, net wealth tax, minimum net wealth tax, municipal business 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

Luxembourg Resident Holders

Under Luxembourg general tax laws currently in force and subject to the law of 23 December 2005, as amended, mentioned in the paragraph below, there is no withholding tax on payments of principal, premium or interest made to Luxembourg resident holders of notes, nor on accrued but unpaid interest in respect of the notes, nor is any Luxembourg withholding tax payable upon redemption or repurchase of the notes held by Luxembourg residents.

Under the law of 23 December 2005, as amended, payments of interest or similar income made or ascribed by a paying agent established in Luxembourg to or for the benefit of an individual beneficial owner who is 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. Payments of interest on the notes, to the extent within the scope of the law of 23 December 2005, as amended, would be subject to withholding tax of 20%.

Non-resident Holders

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 notes, nor on accrued but unpaid interest in respect of the notes, nor is any Luxembourg withholding tax payable upon redemption or repurchase of the notes held by non-residents.

Taxation of Corporate Holders

Luxembourg Resident Corporate Holders

A corporate holder of the notes, who is a resident of Luxembourg for tax purposes or who has a permanent establishment, a fixed place of business or a permanent representative in Luxembourg to which/whom the notes are attributable, is subject to Luxembourg corporation taxes in respect of the interest paid or accrued on the notes.

An individual holder of the notes, who acts in the course of the management of his/her private wealth and who is a resident of Luxembourg for tax purposes, is subject to income tax in respect of interest paid on the notes, except if (i) withholding tax has been levied on such payments in accordance with the law of 23 December 2005, as amended, or (ii) the individual holder of the notes has opted for the application of a 20% tax in full discharge of income tax in accordance with the law of 23 December 2005, as amended, which applies if a payment of interest has been made or ascribed by a paying agent established in a EU member state (other than Luxembourg), or in a member state of the European Economic Area (other than a EU member state).

Under Luxembourg tax laws, a gain realized by an individual holder of the notes, who acts in the course of the management of his private wealth and who is a resident of Luxembourg for tax purposes, on the sale or disposal of the notes, is not subject to Luxembourg income tax, provided this sale or disposal took place after six months of the acquisition of the notes. An individual holder of notes, who acts in the course of the management of his private wealth and who is a resident of Luxembourg for tax purposes, has further to include the portion of the gain corresponding to accrued but unpaid income in respect of the notes in his or her taxable income, except if tax is levied on such interest in accordance with the law of 23 December 2005, as amended.

No Stamp Duty

In principle, neither the issuance nor the transfer, repurchase or redemption of 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 notes in Luxembourg in the case where the 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 notes on a voluntary basis.

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 notes and should be treated with appropriate caution. Particular rules may apply to certain classes of taxpayers holding 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 notes and the receipt of interest thereon under the laws of their country of residence, citizenship or domicile.

Withholding Tax

Tax at the standard rate of income tax (currently 20%) is required to be withheld from payments of Irish source interest. An issuer of notes will not be obliged to withhold tax from payments of interest and premium (if any) on the notes so long as such payments do not constitute Irish source income. Interest and any premium paid on the notes may be treated as having an Irish source if:

•

the issuer is resident in Ireland for tax purposes;

S-37

TABLE OF CONTENTS

•

the issuer has a branch or permanent establishment in Ireland, the assets or income of which are used to fund the payment on the notes; or

•

the issuer is not resident in Ireland for tax purposes but the register for the notes is maintained in Ireland or (if the notes are in bearer form) the notes are physically held in Ireland.

Pentair Finance, the issuer of notes, confirms that it is not and will not be resident in Ireland for tax purposes and that it will not maintain a register of any registered notes in Ireland. If Pentair were to make payments under the guarantee, it is possible that such payments could be treated as having an Irish source, in which case tax at the standard rate of income tax (currently 20%) could be required to be withheld from such payments. We expect that, if such withholding were required, Additional Amounts would be due on such payments, as described in “Description of Debt Securities and Guarantees of Debt Securities — Payment of Additional Amounts” in the accompanying prospectus.

Taxation of Receipts

Notwithstanding that a noteholder may receive payments of interest or premium (if any) on the notes or guarantee payments under the notes free of Irish withholding tax, the noteholder may still be liable to pay Irish income or corporation tax on such interest, premium or guarantee payment if (i) such interest, premium or guarantee payment has an Irish source, (ii) the noteholder is resident or (in the case of a person other than a body corporate) ordinarily resident in Ireland for tax purposes or (iii) the notes are attributed to a branch or agency in Ireland. Noteholders who are individuals may also be liable to pay social insurance (PRSI) contributions and the universal social charge. Ireland operates a self-assessment system in respect of income and corporation tax, and each person must assess its own liability to Irish tax. Relief from Irish income tax may be available under the specific provisions of a double taxation agreement between Ireland and the country of residence of the recipient.

Encashment Tax

Irish tax will be required to be withheld at a rate of 25% from interest or premium paid on notes issued by a company not resident in Ireland, where such interest or premium is collected or realized by a bank or encashment agent in Ireland on behalf of any noteholder.

There is an exemption from encashment tax where the beneficial owner of the interest is (i) not resident in Ireland and has made a declaration to this effect in the prescribed form to the encashment agent or bank or (ii) a company which is within the charge to Irish corporation tax in respect of the interest.

Capital Gains Tax

A noteholder will not be subject to Irish tax on capital gains on a disposal of notes unless such holder is either resident or ordinarily resident in Ireland or carries on a trade or business in Ireland through a permanent establishment, branch or agency in respect of which the notes were used or held.

Stamp Duty

As the issuer is not registered in Ireland, stamp duty will not arise on a document effecting a transfer of the notes so long as (i) the notes do not derive their value or the greater part of their value directly or indirectly from any non-residential immovable property situated in Ireland and (ii) the instrument of transfer of the notes does not relate to:

•

any immoveable property in Ireland or any right over or interest in such property; or

•

stocks or marketable securities of a company registered in Ireland.

United States

The following is a summary of certain U.S. federal income tax consequences relevant to the purchase, ownership and disposition of the notes by a U.S. holder or a non-U.S. holder (each as defined below) that acquires the notes upon original issuance at their initial offering price and holds the notes as “capital assets”

S-38

TABLE OF CONTENTS

within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”) (generally, property held for investment). This summary is based upon provisions of the Code, U.S. Treasury Regulations issued thereunder, U.S. Internal Revenue Service (“IRS”) rulings and pronouncements and judicial decisions, all as of the date hereof. These authorities may be changed, possibly with retroactive effect, so as to result in U.S. federal income tax consequences different from those summarized below. Prospective investors should be aware that no ruling will be sought from the IRS with respect to the matters discussed below, and there can be no assurance that the IRS will not take a different position concerning the U.S. federal income tax consequences of the purchase, ownership or disposition of the notes or that any such position would not be sustained.

This summary does not discuss all aspects of U.S. federal income taxation that may be important to particular investors in light of their individual circumstances or to holders subject to special tax rules, such as financial institutions, banks, thrifts, insurance companies, broker-dealers, traders in securities that elect to use a mark-to-market method of accounting, certain U.S. expatriates, tax-exempt organizations (including private foundations), governmental organizations, qualified retirement plans, regulated investment companies, real estate investment trusts, persons that will hold the notes as a part of a straddle, hedge, wash sale, conversion, constructive sale or other integrated transaction for U.S. federal income tax purposes, entities or arrangements treated as partnerships for U.S. federal income tax purposes and partners in such partnerships, subchapter S corporations or other pass-through entities, persons subject to special tax accounting rules under Section 451(b) of the Code, controlled foreign corporations, passive foreign investment companies, corporations that accumulate earnings to avoid U.S. federal income tax, U.S. holders that hold their notes through non-U.S. brokers or other non-U.S. intermediaries, and U.S. holders whose functional currency is not the U.S. dollar. In addition, this summary does not address U.S. federal estate or gift tax laws, U.S. federal alternative minimum tax consequences or the tax considerations arising under the laws of any state, local or non-U.S. jurisdiction. For purposes of this summary, a “U.S. holder” is a beneficial owner of the notes that is (a) an individual who is a citizen of the United States or who is resident in the United States for U.S. federal income tax purposes, (b) an entity that is classified for U.S. federal income tax purposes as a corporation and that is organized under the laws of the United States, any state thereof, or the District of Columbia, or is otherwise treated for U.S. federal income tax purposes as a domestic corporation, (c) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (d) a trust (i) whose administration is subject to the primary supervision of a court within the United States and all substantial decisions of which are subject to the control of one or more United States persons as described in Section 7701(a)(30) of the Code (“United States persons”), or (ii) that has a valid election in effect under applicable Treasury Regulations to be treated as a United States person.

For purposes of this summary, a “non-U.S. holder” is a beneficial owner of notes (other than an entity that is classified for U.S. federal income tax purposes as a partnership or as a “disregarded entity”) that is not a U.S. holder. If an entity classified for U.S. federal income tax purposes as a partnership or as a “disregarded entity” owns notes, the tax treatment of a member of the entity will depend on the status of the member and the activities of the entity. The tax treatment of such an entity, and the tax treatment of any member of such an entity, are not addressed in this summary. Any entity that is classified for U.S. federal income tax purposes as a partnership or as a “disregarded entity” and that owns notes, and any members of such an entity, are encouraged to consult their own tax advisors.

U.S. Holders

Certain Contingent Payments

In certain circumstances, we may be obligated to pay amounts in excess of the stated interest or principal on the notes (see “Description of Notes — Change of Control” and “Description of Notes — Special Mandatory Redemption”). The obligation to make such payments may implicate the provisions of U.S. Treasury Regulations relating to “contingent payment debt instruments.” Under applicable U.S. Treasury Regulations, the possibility that such an amount will be paid will not affect the amount, timing or character of income recognized by a holder with respect to the notes if, as of the date the notes were issued, there is only a remote chance that such an amount will be paid, the amount is incidental or certain other exceptions apply. We intend to take the position that the contingencies associated with the notes should not cause the notes to be subject to the contingent payment debt instrument rules. Our determination

S-39

TABLE OF CONTENTS

is binding on a holder unless such holder discloses its contrary position in the manner required by applicable U.S. Treasury Regulations. Our determination is not, however, binding on the IRS, and if the IRS were to successfully challenge this determination, a U.S. holder might be required to accrue interest income at a higher rate than the stated interest rate on the notes, and to treat as ordinary income any gain realized on the taxable disposition of a note. The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments. Holders are urged to consult their own tax advisors regarding the potential application to the notes of the contingent payment debt instrument rules and the consequences thereof.

Interest

It is anticipated, and this summary assumes, that the notes will be issued with less than a de minimis amount of original issue discount, if any (as determined under the Code). Payments of stated interest on the notes (including any non-U.S. tax withheld on such payments and any Additional Amounts paid with respect thereto) will be included in a U.S. holder’s gross income as ordinary interest income at the time such payments are received or accrued in accordance with the U.S. holder’s usual method of accounting for U.S. federal income tax purposes. As a result of the inclusion of any amounts attributable to withheld non-U.S. taxes and Additional Amounts, the amount included in a U.S. holder’s gross income for U.S. federal income tax purposes with respect to a payment of interest may be greater than the amount of cash actually received (or receivable) by such U.S. holder.

Income earned by a U.S. holder with respect to the notes will generally constitute foreign-source income for purposes of computing the foreign tax credit allowable under the U.S. federal income tax laws. The limitation on foreign income taxes eligible for credit is calculated separately with respect to specific classes of income. In this regard, interest income in respect of the notes will constitute “passive category income” for most U.S. holders.

Any non-U.S. income taxes withheld from interest payments on a note will generally be allowed as a credit against a U.S. holder’s U.S. federal income tax liability, subject to applicable limitations that may vary depending upon the U.S. holder’s particular circumstances. Alternatively, the U.S. holder may deduct such non-U.S. income taxes in computing U.S. taxable income, provided that the U.S. holder elects to deduct (rather than credit) all foreign income taxes paid or accrued during the taxable year. The rules governing foreign tax credits and the deduction of foreign income taxes are complex and, therefore, U.S. holders are encouraged to consult their tax advisors regarding the availability of foreign tax credits or deductions in their particular circumstances.

Sale, Exchange, Retirement or Other Taxable Disposition of Notes

Upon a sale, exchange, retirement or other taxable disposition of notes, a U.S. holder will generally recognize gain or loss in an amount equal to the difference between the amount of cash and the fair market value of any property received on the disposition (other than any amount attributable to accrued but unpaid interest, which will be treated as ordinary income to the extent not previously included in income) and the U.S. holder’s adjusted tax basis in such notes. A U.S. holder’s adjusted tax basis in a note will generally equal the U.S. dollar cost of the note to such holder.

Any such gain or loss will generally be treated as capital gain or loss and will be treated as long-term capital gain or loss if the U.S. holder’s holding period in the notes exceeds one year at the time of the disposition. Long-term capital gains of non-corporate taxpayers are subject to reduced rates of taxation. The deductibility of capital losses is subject to limitations.

If any non-U.S. income tax is withheld on the sale or other taxable disposition of a note, the amount realized by a U.S. holder will include the gross amount of the proceeds of that sale or other taxable disposition before deduction of such tax. Capital gain or loss, if any, recognized by a U.S. holder on the sale or other taxable disposition of a note will generally be treated as U.S. source gain or loss for U.S. foreign tax credit purposes. Prospective investors should consult their own tax advisors as to the foreign tax credit implications of the sale, retirement or other taxable disposition of the Notes.

TABLE OF CONTENTS

Additional Tax on Net Investment Income

Certain U.S. holders that are not corporations will generally be subject to a 3.8% tax (the “Medicare tax”) on the lesser of (1) the U.S. holder’s “net investment income” (or “undistributed net investment income” in the case of an estate or trust) for the taxable year and (2) the excess of the U.S. holder’s modified adjusted gross income for the taxable year over a certain threshold. A U.S. holder’s net investment income will generally include any income or gain recognized by such holder with respect to the notes, unless such income or gain is derived in the ordinary course of the conduct of such holder’s trade or business (other than a trade or business that consists of certain passive or trading activities). Each U.S. Holder that is an individual, estate or trust is urged to consult its tax advisors regarding the applicability of the Medicare tax to its income and gains in respect of its investment in the notes.

Foreign Financial Asset Reporting

U.S. holders who are individuals (and certain entities) that own “specified foreign financial assets” with an aggregate value in excess of certain reporting thresholds are generally required to file an information report with respect to such assets with their tax returns, subject to certain exceptions. The notes are generally expected to constitute specified foreign financial assets subject to these reporting requirements (unless the notes are held in an account at a U.S. financial institution). U.S. holders are encouraged to consult their own tax advisor as to the possible application of this information reporting requirement.

Backup Withholding and Information Reporting

Information reporting requirements will generally apply to payments of interest on the notes within the United States and to the proceeds from a sale, exchange, retirement or other taxable disposition of notes effected at a U.S. office of a broker unless a U.S. holder is an exempt recipient and appropriately establishes that exemption. In addition, backup withholding will apply to any such payments or proceeds if a U.S. holder fails to provide a correct taxpayer identification number or certification of exempt status, or if the U.S. holder is notified by the IRS that it has failed to report in full payments of interest and dividend income, or if the U.S. holder otherwise fails to comply with applicable requirements of the backup withholding rules.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a credit against a U.S. holder’s U.S. federal income tax liability and may entitle such U.S. holder to a refund, provided that the required information is timely provided to the IRS.

Non-U.S. Holders

Payments on the notes to a non-U.S. holder and gain realized by a non-U.S. holder on its disposition of the notes will not generally be subject to U.S. federal income or withholding tax, unless (1) any such payment or gain is effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained in the United States by such non-U.S. holder) or (2) in the case of gain, the non-U.S. holder is an individual who is present in the United States for 183 days or more during the taxable year of the disposition and certain other conditions are met.

Backup Withholding and Information Reporting

In general, payments of principal and interest on the notes, and payments of the proceeds of a sale, exchange, retirement or other taxable disposition of notes, paid within the United States or through certain U.S.-related financial intermediaries to a non-U.S. holder, may be subject to information reporting and backup withholding unless the non-U.S. holder complies with certification procedures to establish that it is not a United States person or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a credit against the non-U.S. holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely provided to the IRS.

Foreign Account Tax Compliance

Pursuant to Sections 1471 through 1474 of the Code (provisions commonly known as “FATCA”) and related intergovernmental agreements, from no earlier than the date that is two years after the date on which applicable Treasury Regulations defining “foreign passthru payments” are filed, the Issuer may be required to withhold U.S. tax on certain payments on the notes to the extent such payments are considered to be “foreign passthru payments.” Obligations issued on or prior to the date that is six months after the date on which applicable final Treasury Regulations defining “foreign passthru payments” are filed generally would be “grandfathered” unless such obligations are materially modified after such date. As of the date of this prospectus supplement, applicable final Treasury Regulations defining “foreign passthru payments” have not yet been filed. Thus, payments on the notes would be considered “foreign passthru payments” subject to FACTA withholding only if there is a significant modification of the notes for U.S. federal income tax purposes after the expiration of this grandfathering period. In the event any withholding under FATCA is imposed with respect to any payments on the notes, there generally will be no Additional Amounts payable to compensate for the withheld amount.

Certain non-U.S. governments have entered into, and others are expected to enter into, intergovernmental agreements with the United States to implement FATCA in a manner that may alter the rules described herein. Holders are encouraged to consult their own tax advisors on how these rules may apply to their investment in the notes.

The above discussion is intended only as a general summary of certain aspects of U.S. federal income tax law and does not constitute a complete analysis of all tax consequences relating to the purchase, ownership and disposition of the notes. Prospective investors are encouraged to consult their own independent tax advisors concerning the U.S. federal, state, local and non-U.S. income and other tax consequences to them based upon their particular circumstances.

UNDERWRITING

We and the underwriters for the offering named below, for whom J.P. Morgan Securities LLC, BofA Securities, Inc. and Citigroup Global Markets Inc. are acting as representatives, have entered into an underwriting agreement with respect to the notes. Subject to the terms and conditions of the underwriting agreement, each underwriter has severally, and not jointly, agreed to purchase the principal amount of the notes indicated in the following table.

Underwriters	Principal Amount of Notes
J.P. Morgan Securities LLC		$
BofA Securities, Inc.
Citigroup Global Markets Inc.
Total		$

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. The underwriters are committed to take and pay for all of the notes being offered, if any such notes are taken.

Notes sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus supplement. Any notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price of up to % of the principal amount of the notes. Any such securities dealers may resell any notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price of up to % of the principal amount of the notes. If all the notes are not sold at the initial public offering price, the underwriters may change the offering price and the other selling terms. The underwriters may offer and sell notes through certain of their affiliates.

The notes are a new issue of securities with no established trading market and we do not intend to apply for listing of the notes on any securities exchange or for inclusion of the notes on any automated quotation system. 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 engage in stabilizing transactions, over-allotment transactions and syndicate covering transactions.

•

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

•

Over-allotment involves sales by the underwriters of notes in excess of the principal amount of the notes the underwriters are obligated to purchase, which creates a syndicate short position.

•

Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the notes in the open market after pricing that could adversely affect investors who purchase in the offering.

These stabilizing transactions, over-allotment transactions and syndicate covering transactions may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

S-43

TABLE OF CONTENTS

It is expected that delivery of the notes will be made against payment therefor on or about , 2022, which is the seventh business day following the date hereof (such settlement cycle being referred to as “T+7”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to the date that is the second business day before delivery of the notes will be required, by virtue of the fact that the notes initially will settle in T+7, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes prior to the date that is the second business day before delivery of the notes should consult their own advisors.

The following table shows the underwriting discount that we will pay to the underwriters in connection with the offering of the notes:

			Paid by us
Per note					%

We estimate that the total expenses for this offering will be $2.3 million, excluding the underwriting discount.

We have agreed to indemnify the several underwriters against some specified types of liabilities, including liabilities under the Securities Act, and to contribute to payments the underwriters may be required to make in respect of any of these liabilities.

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, investment research, principal investment, hedging, market making, financing and brokerage activities.

Certain of the underwriters and their affiliates have provided in the past to us and our affiliates and may provide from time to time in the future certain commercial banking, financial advisory, investment banking and other financial and non-financial services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive, or may in the future receive, customary fees and commissions. For example, J.P. Morgan Securities LLC has acted as our financial advisor in connection with the Manitowoc Ice acquisition. The underwriters for this offering and/or their affiliates are lenders and/or agents under the term loan financing. Also, certain of the underwriters and/or their affiliates are lenders and/or agents under our existing term loan facility and revolving credit facility. In addition, the underwriters and/or their affiliates have agreed to provide us with the bridge facility that we may draw upon in the event that this offering is not consummated. The amount of the commitments under the bridge facility will be reduced on a dollar-for-dollar basis by the principal amount of the notes offered hereby.

Certain of the underwriters and their affiliates that have a lending relationship with us routinely hedge, and certain 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 notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future. 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 (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the issuer. The underwriters and their affiliates may also make investment recommendations and/or publish or express

independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

(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 notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes.

Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

DESCRIPTION OF DEBT SECURITIES
AND GUARANTEES OF DEBT SECURITIES

The following is a general description of the debt securities that we 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 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.

Pentair Finance S.à r.l., or Pentair Finance, is the issuer of the applicable series of debt securities and references to Pentair Finance in this description do not, unless the context otherwise indicates, include any of its subsidiaries. References to Pentair in this description refer to Pentair plc, not including its subsidiaries. Capitalized terms used but not defined in this section have the respective meanings set forth in the applicable indenture.

General

The debt securities that we offer will be senior unsubordinated debt securities. Pentair Finance will issue senior debt securities under the indenture, dated as of September 16, 2015, among Pentair Finance, Pentair and U.S. Bank Trust Company, National Association (as successor to U.S. Bank National Association), as trustee. We refer to this indenture, as supplemented by the seventh supplemental indenture, dated as of June 22, 2020, as the indenture, and to the trustee under the indenture as the trustee. In addition, the indenture may be supplemented or amended as necessary to set forth the terms of the debt securities issued under the indenture. You should read the indenture, including any amendments or supplements, carefully to fully understand the terms of the debt securities. The indenture has been filed as an exhibit to the registration statement of which this prospectus is a part. The indenture is subject to, and is governed by, the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The senior debt securities will be unsubordinated obligations of Pentair Finance. They will rank equally with each other and all of Pentair Finance’s other unsubordinated debt, unless otherwise indicated in the applicable prospectus supplement.

Debt securities issued by Pentair Finance will be fully and unconditionally guaranteed by Pentair, unless otherwise specified in an applicable prospectus supplement. The debt securities will not be guaranteed by, and therefore will not constitute obligations of, Pentair Finance’s or Pentair’s subsidiaries other than Pentair Finance. Creditors of Pentair Finance’s subsidiaries are entitled to a claim on the assets of those subsidiaries. Consequently, in the event of a liquidation or reorganization of any subsidiary, creditors of a subsidiary are likely to be paid in full before any distribution is made to Pentair Finance and holders of its debt securities, except to the extent that Pentair Finance is itself recognized as a creditor of that subsidiary, in which case Pentair Finance’s claims would still be subordinate to any security interests in the assets of the subsidiary and any debt of the subsidiary senior to that held by Pentair Finance.

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. Unless otherwise provided in the applicable prospectus supplement, the indenture does not limit the amount of other indebtedness or securities that we may issue. We may issue debt securities of the same series at more than one time and, unless prohibited by the terms of the series, we may reopen a series for issuances of additional debt securities without the consent of the holders of the outstanding debt securities of that series. All debt securities issued as a series, including those issued pursuant to any reopening of a series, will vote together as a single class.

Reference is made to the prospectus supplement for the following and other possible terms of each series of the debt securities in respect of which this prospectus is being delivered:

•

the title of the debt securities;

The statements made hereunder relating to the indenture and the debt securities are summaries of certain provisions thereof and are qualified in their entirety by reference to all provisions of the indenture and the debt securities and the descriptions thereof, if different, in the applicable prospectus supplement.

Guarantees

Unless otherwise specified in an applicable prospectus supplement, Pentair will fully and unconditionally guarantee the due and punctual payment of the principal of, premium, if any, and interest on any debt securities issued by Pentair Finance, when and as the same shall become due and payable, whether at maturity, upon redemption, by acceleration or otherwise. The guarantee provides that in the event of a default in payment on a debt security, the holder of the debt security may institute legal proceedings directly against Pentair to enforce the guarantee without first proceeding against Pentair Finance.

Redemption at Pentair Finance’s Option

If specified in the applicable prospectus supplement, Pentair Finance may redeem the debt securities of any series, as a whole or in part, at Pentair Finance’s option on and after the dates and in accordance with

TABLE OF CONTENTS

the terms established for such series, if any, in the applicable prospectus supplement. If Pentair Finance redeems the debt securities of any series, Pentair Finance also must pay accrued and unpaid interest, if any, to the date of redemption on such debt securities.

Redemption Upon Changes in Withholding Taxes

Pentair Finance may redeem all, but not less than all, of the debt securities of any series under the following conditions:

•

If there is an amendment to, or change in, the laws or regulations of Luxembourg, Switzerland, Ireland, the United Kingdom or the United States, as applicable, or any political subdivision thereof or therein having the power to tax (a “Taxing Jurisdiction”), or any change in the application or official interpretation of such laws, including any action taken by a taxing authority or a holding by a court of competent jurisdiction, regardless of whether such action, change or holding is with respect to Pentair Finance or Pentair;

•

As a result of such amendment or change, Pentair Finance or Pentair becomes, or there is a material probability that Pentair Finance or Pentair will become, obligated to pay Additional Amounts, as defined below in “Payment of Additional Amounts,” on the next payment date with respect to the debt securities of such series;

•

The obligation to pay Additional Amounts cannot be avoided through Pentair Finance’s or Pentair’s commercially reasonable measures;

•

Pentair Finance delivers to the trustee:

•

a certificate of Pentair Finance and Pentair, stating that the obligation to pay Additional Amounts cannot be avoided by Pentair Finance or Pentair, as the case may be, taking commercially reasonable measures available to it; and

•

a written opinion of independent legal counsel to Pentair Finance or Pentair, as the case may be, of recognized standing to the effect that Pentair Finance or Pentair, as the case may be, has, or there is a material probability that it will become obligated, to pay Additional Amounts as a result of a change, amendment, official interpretation or application described above and that Pentair Finance or Pentair, as the case may be, cannot avoid the payment of such Additional Amounts by taking commercially reasonable measures available to it; and

•

Following the delivery of the certificate and opinion described in the previous bullet point, Pentair Finance provides notice of redemption not less than 30 days, but not more than 90 days, prior to the date of redemption. The notice of redemption cannot be given more than 90 days before the earliest date on which Pentair Finance or Pentair would be otherwise required to pay Additional Amounts, and the obligation to pay Additional Amounts must still be in effect when the notice is given.

Upon the occurrence of each of the bullet points above, Pentair Finance may redeem the debt securities of such series at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but excluding, the redemption date.

Notice of Redemption

Notice of any redemption will be mailed at least 30 days but not more than 90 days before the redemption date to the trustee and each holder of debt securities of a series to be redeemed at its address shown in the debt security register for the debt securities. If Pentair Finance elects to redeem a portion but not all of such debt securities, the trustee will select the debt securities to be redeemed in accordance with a method determined by Pentair Finance, in such manner as complies with applicable legal requirements, the rules and procedures of The Depository Trust Company, if applicable, and stock exchange requirements, if any.

Interest on such debt securities or portions of debt securities will cease to accrue on and after the date fixed for redemption, unless Pentair Finance defaults in the payment of such redemption price and accrued interest with respect to any such security or portion thereof.

TABLE OF CONTENTS

If any date of redemption of any security 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 date of redemption and no interest will accrue for the period after such nominal date.

Payment of Additional Amounts

Unless otherwise required by law, neither Pentair Finance nor Pentair will deduct or withhold from payments made by Pentair Finance or Pentair under or with respect to the debt securities and the guarantees on account of any present or future taxes, duties, levies, imposts, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any Taxing Jurisdiction (“Taxes”). In the event that Pentair Finance or Pentair is required to withhold or deduct any amount for or on account of any Taxes from any payment made under or with respect to any debt securities or guarantee, as the case may be, Pentair Finance or Pentair, as the case may be, will pay such additional amounts (“Additional Amounts”) so that the net amount received by each holder of debt securities (including Additional Amounts) after such withholding or deduction will equal the amount that such holder 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 of debt securities or a holder of beneficial interests in global securities where such holder is subject to taxation on such payment by a relevant Taxing Jurisdiction for any reason other than such holder’s mere ownership of the securities or for or on account of:

•

any Taxes that are imposed or withheld solely because such holder or a fiduciary, settlor, beneficiary, or member of such holder if such holder is an estate, trust, partnership, limited liability company or other fiscally transparent entity, or a person holding a power over an estate or trust administered by a fiduciary holder:

•

is or was present or engaged in, or is or was treated as present or engaged in, a trade or business in the Taxing Jurisdiction or has or had a permanent establishment in the Taxing Jurisdiction;

•

has or had any present or former connection (other than the mere fact of ownership of such securities) with the Taxing Jurisdiction imposing such taxes, including being or having been a citizen or resident thereof or being treated as being or having been a resident thereof;

•

with respect to any withholding taxes imposed by the United States, is or was with respect to the United States a personal holding company, a passive foreign investment company, a controlled foreign corporation, a foreign tax exempt organization or corporation that has accumulated earnings to avoid United States federal income tax; or

•

owns or owned 10% or more of the total combined voting power of all classes of stock or shares of Pentair Finance or Pentair;

•

any estate, inheritance, gift, sales, transfer, excise, personal property or similar Taxes imposed with respect to the securities, except as otherwise provided in the indenture;

•

any Taxes imposed solely as a result of the presentation of such debt securities, where presentation is required, for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever is later, except to the extent that the beneficiary or holder thereof would have been entitled to the payment of Additional Amounts had such debt securities been presented for payment on any date during such 30-day period;

•

any Taxes imposed or withheld solely as a result of the failure of such holder or any other person to comply with applicable certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connection with the Taxing Jurisdiction of such holder, if such compliance is required by statute or regulation of the relevant Taxing Jurisdiction as a precondition to relief or exemption from such Taxes;

•

with respect to withholding Taxes imposed by the United States, any such Taxes imposed by reason of the failure of such holder to fulfill the statement requirements of Sections 871(h) or 881(c) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”);

TABLE OF CONTENTS

•

any Taxes that are payable by any method other than withholding or deduction by Pentair Finance, Pentair or any paying agent from payments in respect of such securities;

•

any Taxes required to be withheld by any paying agent from any payment in respect of any securities if such payment can be made without such withholding by at least one other paying agent;

•

any Taxes required to be deducted or withheld pursuant to any directive implementing the conclusions of the ECOFIN Council meeting of November 26 and 27, 2000, on the taxation of savings income in the form of interest payments (or any amendment thereof), or any law implementing or complying with, or introduced in order to conform to, any such directive or the Luxembourg Law of December 23, 2005, as amended;

•

any withholding or deduction for Taxes which would not have been imposed if the relevant Securities had been presented to another paying agent in a Member State of the European Union;

•

any Taxes imposed or withheld by reason of a change in law, regulation or administrative or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever occurs later; or

•

any combination of the above conditions.

Additional Amounts will not be payable to or for the account of any holder of securities or holder of a beneficial interest in such securities if such payment would not be subject to such withholding or deduction of Taxes but for the failure of such holder of securities or holder of a beneficial interest in such securities to make a valid declaration of non-residence or other similar claim for exemption or to provide a certificate declaring its non-residence, if Pentair Finance were treated as a domestic corporation under United States federal income tax laws and if (x) the making of such declaration or claim or the provision of such certificate is required or imposed by statute, treaty, regulation, ruling or administrative practice of the relevant taxing authority as a precondition to an exemption from, or reduction in, the relevant Taxes, and (y) at least 60 days prior to the first payment date with respect to which Pentair or Pentair Finance shall apply this paragraph, Pentair or Pentair Finance shall have notified all holders of securities in writing that they shall be required to provide such declaration or claim.

Additional Amounts also will not be payable to any holder of securities or the holder of a beneficial interest in a global security that is a fiduciary, partnership, limited liability company or other fiscally transparent entity, or to such holder that is not the sole holder of such security or holder of such beneficial interests in such security, as the case may be. The exception, however, will apply only to the extent that a beneficiary or settlor with respect to the fiduciary, or a beneficial owner or member of the partnership, limited liability company or other fiscally transparent entity would not have been entitled to the payment of an Additional Amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment. In addition, no Additional Amounts will be paid on account of any taxes imposed or withheld pursuant to Sections 1471 through 1474 of the Code (or any amended or successor version that is substantively comparable) and any current or future regulations promulgated thereunder or official interpretations thereof.

Each of Pentair Finance and Pentair, as applicable, also:

•

will make such withholding or deduction of Taxes;

•

will remit the full amount of Taxes so deducted or withheld to the relevant Taxing Jurisdiction in accordance with all applicable laws;

•

will use its commercially reasonable efforts to obtain from each Taxing Jurisdiction imposing such Taxes certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld; and

•

upon request, will make available to the holders of the debt securities, within 90 days after the date the payment of any Taxes deducted or withheld is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by Pentair Finance or Pentair or if, notwithstanding Pentair Finance’s or Pentair’s efforts to obtain such receipts, the same are not obtainable, other evidence of such payments.

TABLE OF CONTENTS

At least 30 days prior to each date on which any payment under or with respect to the debt securities of a series or guarantees is due and payable, if Pentair Finance or Pentair will be obligated to pay Additional Amounts with respect to such payment, Pentair Finance or Pentair 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 debt securities on the payment date.

In addition, Pentair Finance will pay any stamp, issue, registration, documentary or other similar taxes and duties, including interest, penalties and Additional Amounts with respect thereto, payable in Luxembourg or the United States or any political subdivision or taxing authority of or in the foregoing in respect of the creation, issue, offering, enforcement, redemption or retirement of the debt securities except for any Luxembourg registration duties (droits d’enregistrement), that would become payable as a result of the registration by a holder of securities or a holder of a beneficial interest in a global security of any agreement relating to the debt securities with the Administration de l’enregistrement des domaines et de la TVA in Luxembourg, when such registration is not required to enforce such holder’s rights under such agreement.

The foregoing provisions shall survive any termination or the discharge of each indenture and shall apply to any jurisdiction in which Pentair Finance, Pentair or any successor to Pentair Finance or Pentair, as the case may be, is organized or is engaged in business for tax purposes or any political subdivisions or taxing authority or agency thereof or therein.

Whenever in an indenture, any debt securities, any guarantee or in this “Description of Debt Securities and Guarantees of Debt Securities” there is mentioned, in any context, the payment of principal, premium, if any, redemption price, interest or any other amount payable under or with respect to any debt securities, such mention includes the payment of Additional Amounts to the extent payable in the particular context.

Certain Covenants

Affirmative Covenants

Under the indenture:

•

Pentair Finance will duly and punctually pay or cause to be paid the principal of, premium, if any, and interest on the debt securities;

•

Pentair Finance will maintain an office or agency where securities may be presented or surrendered for payment; and

•

Pentair and Pentair Finance will furnish to the trustee on or before April 30 of each year a certificate executed by the principal executive, financial or accounting officer of each of Pentair and Pentair Finance on their respective behalf as to such officer’s knowledge of Pentair’s or Pentair Finance’s, as the case may be, compliance with all covenants and agreements under the indenture required to be complied with by Pentair and Pentair Finance, respectively.

Reports by Pentair Finance

So long as any debt securities are outstanding, Pentair Finance shall file with the trustee, within 15 days after Pentair files 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 Pentair may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act. Pentair Finance 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 Pentair Finance’s compliance with any of its covenants under the indenture (as to which the trustee is entitled to rely exclusively on officer’s certificates).

TABLE OF CONTENTS

Limitation on Mergers and Other Transactions

Each of Pentair and Pentair Finance covenants that it will not merge or consolidate with any other person or sell or convey all or substantially all of its assets to any person, unless:

•

either Pentair or Pentair Finance, as the case may be, shall be the continuing entity, or the successor entity or the person which acquires by sale or conveyance substantially all the assets of Pentair or Pentair Finance, as the case may be (if other than Pentair or Pentair Finance, as the case may be), (A) shall expressly assume the due and punctual payment of the principal of, premium, if any, and interest on the debt securities or the obligations under the guarantees, as the case may be, according to their tenor, and the due and punctual performance and observance of all of the covenants and agreements of the indenture to be performed or observed by Pentair or Pentair Finance, as the case may be, by supplemental indenture reasonably satisfactory to the trustee, executed and delivered to the trustee by such person, and (B) shall be an entity treated as a “corporation” for U.S. tax purposes or Pentair or Pentair Finance, as the case may be, and obtains either (x) an opinion, in form and substance reasonably acceptable to the trustee, of tax counsel of recognized standing reasonably acceptable to the trustee, which counsel shall include Foley & Lardner LLP, or (y) a ruling from the U.S. Internal Revenue Service, in either case to the effect that such merger or consolidation, or such sale or conveyance, will not result in an exchange of the debt securities for new debt instruments for U.S. federal income tax purposes; and

•

Pentair Finance shall deliver to the trustee prior to or simultaneously with the consummation of the proposed transaction an officer’s certificate to the foregoing effect and an opinion of counsel stating that the proposed transaction and any such supplemental indenture comply with the indenture.

Events of Default

With respect to debt securities of a particular series, an “Event of Default” means any one or more of the following events that has occurred and is continuing, except with respect to any series of debt securities for which the supplemental indenture or resolution of the board of directors under which such series of debt securities is issued or the form of security for such series expressly provides that any such Event of Default shall not apply to such series of debt securities:

default in the payment of any installment of interest upon any of the debt securities of such series as and when the same shall become due and payable, and continuance of such default for a period of 30 days;

default in the payment of all or any part of the principal of or premium, if any, on any of the debt securities of such series as and when the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise;

default in the payment of any sinking fund installment as and when the same shall become due and payable by the terms of the debt securities of such series;

default in the performance, or breach, of any covenant or agreement of Pentair or Pentair Finance in respect of the debt securities of such series and the related guarantee (other than a default or breach that is specifically dealt with elsewhere), and continuance of such default or breach for a period of 90 days after the date on which there has been given, by registered or certified mail, to Pentair and Pentair Finance by the trustee or to Pentair, Pentair Finance and the trustee by the holders of at least 25% in principal amount of the outstanding debt securities of such series, a written notice specifying such default or breach and requiring it to be remedied and stating that the notice is a “Notice of Default” under the indenture;

TABLE OF CONTENTS

the guarantee with respect to the debt securities of such series shall for any reason cease to be, or shall for any reason be asserted in writing by Pentair or Pentair Finance not to be, in full force and effect and enforceable in accordance with its terms except to the extent contemplated by the indenture and such guarantee;

a court having jurisdiction in the premises shall enter a decree or order for relief in respect of Pentair Finance or Pentair in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator or similar official of Pentair Finance or Pentair or for any substantial part of its property or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of 90 consecutive days;

Pentair Finance or Pentair shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator or similar official of Pentair Finance or Pentair or for any substantial part of its property, or make any general assignment for the benefit of creditors; or

any other Event of Default provided in the supplemental indenture or resolution of the board of directors under which such series of debt securities is issued or in the form of security for such series.

If an Event of Default shall have occurred and be continuing in respect of the debt securities of a series, in each and every case, unless the principal of all the debt securities of the series shall have already become due and payable, either the trustee at the request of the holder or the holders of not less than 25% in aggregate principal amount of the debt securities of such series then outstanding, by notice in writing to Pentair and Pentair Finance, as applicable, and to the trustee if given by such holder or holders, may declare the unpaid principal of all the debt securities of that series to be due and payable immediately.

The holders of a majority in aggregate principal amount of debt securities of any series, by written notice to Pentair and Pentair Finance and the trustee, may waive any existing default in the performance of any of the covenants contained in the indenture or established with respect to such series and its consequences, except a default in the payment of the principal of, premium, if any, or interest on, any of the debt securities of that series as and when the same shall become due by the terms of such securities. Upon any such waiver, the default covered thereby and any Event of Default arising therefrom shall be deemed to be cured for all purposes of the indenture.

The holders of a majority in aggregate principal amount of the outstanding debt securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such series; provided, however, that such direction shall not be in conflict with any rule of law or with the indenture or be unduly prejudicial to the rights of holders of securities of any other outstanding series. Subject to the terms of the indenture, the trustee shall have the right to decline to follow any such direction if the trustee in good faith, by a responsible officer or responsible officers of the trustee, shall determine that the proceeding so directed would involve the trustee in personal liability.

No holder of any debt security of any series shall have any right to institute any suit, action or proceeding in equity or at law under the indenture or to appoint a receiver or trustee, or to seek any other remedies under the indenture unless:

•

such holder previously shall have given to the trustee written notice of an Event of Default and the continuance thereof specifying such Event of Default;

•

the holders of not less than 25% in aggregate principal amount of the debt securities of such series then outstanding shall have made written request upon the trustee to institute such action, suit or proceeding in its own name as trustee;

•

such holder or holders shall have offered to the trustee such indemnity and security reasonably satisfactory to it against the costs, expenses and liabilities to be incurred therein or thereby;

TABLE OF CONTENTS

•

the trustee, for 60 days after its receipt of such written notice, request and offer of indemnity and security reasonably satisfactory to it, shall have failed to institute any such action, suit or proceeding; and

•

during such 60 day period, the holders of a majority in principal amount of the debt securities of that series do not give the trustee a direction inconsistent with such request.

The right of any holder to receive payment of principal of, and premium, if any, and interest on such security or to institute suit for the enforcement of any such payment shall not be impaired or affected without the consent of such holder.

Modification of the Indenture

Pentair Finance, Pentair and the trustee may from time to time and at any time enter into an indenture or indentures supplemental to the indenture without the consent of any holders of any series of debt securities for one or more of the following purposes:

•

to cure any ambiguity, defect or inconsistency in the indenture or debt securities of any series, including making any such changes as are required for the indenture to comply with the Trust Indenture Act;

•

to add an additional obligor on the debt securities or to add a guarantor of any outstanding series of debt securities, or to evidence the succession of another person to Pentair or Pentair Finance, or successive successions, and the assumption by the successor person of the covenants, agreements and obligations of Pentair or Pentair Finance, as the case may be, pursuant to provisions in the indenture described under “Certain Covenants — Limitations on Mergers and Other Transactions”;

•

to provide for uncertificated debt securities in addition to or in place of certificated debt securities;

•

to add to the covenants of Pentair Finance for the benefit of the holders of any outstanding series of debt securities or to surrender any of Pentair Finance’s or Pentair’s rights or powers under the indenture;

•

to add any additional Events of Default for the benefit of the holders of any outstanding series of debt securities;

•

to change or eliminate any of the provisions of the indenture, provided that any such change or elimination shall not become effective with respect to any outstanding debt security of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision;

•

to secure the debt securities of any series;

•

to make any other change that does not adversely affect the rights of any holder of outstanding debt securities of the affected series in any material respect;

•

to provide for the issuance of and establish the form and terms and conditions of a series of debt securities, to provide which, if any, of the covenants of Pentair Finance shall apply to such series, to provide which of the Events of Default it shall apply to such series, to name one or more guarantors and provide for guarantees of such series, to provide for the terms and conditions upon which the guarantee by Pentair of such series may be released or terminated, or to define the rights of the holders of such series of debt securities;

•

to issue additional debt securities of any series; provided that such additional debt securities have the same terms as, and be deemed part of the same series as, the applicable series of debt securities to the extent required under the indenture;

•

to evidence and provide for the acceptance of appointment by a successor trustee with respect to the debt securities of one or more series and to add to or change any of the provisions of the indenture as shall be necessary to provide for or facilitate the administration of the trust by more than one trustee;

•

to supplement any of the provisions in the indenture to permit or facilitate the defeasance and discharge of the debt securities of any series in a manner consistent with the provisions described

TABLE OF CONTENTS

under “Satisfaction and Discharge of Indenture”; provided, however, that any such action shall not adversely affect the interest of the holders of debt securities of such series or any other series in any material respect; or

•

to conform the text of the indenture, any supplemental indenture or any debt securities to the description thereof in any prospectus, prospectus supplement or offering circular or memorandum or supplement thereto with respect to the offer and sale of debt securities of any series, to the extent than such description is inconsistent with a provision in the indenture, any supplemental indenture or debt security, as provided in an officer’s certificate.

In addition, under the indenture, with the written consent of the holders of not less than a majority in aggregate principal amount of the debt securities of each series at the time outstanding that is affected, Pentair and Pentair Finance, when authorized by board resolutions, and the trustee, from time to time and at any time may enter into an indenture or indentures to supplement the indenture. However, the following changes may only be made with the consent of each holder of outstanding debt securities affected:

•

extend a fixed maturity of or any installment of principal of any debt securities of any series or reduce the principal amount thereof or reduce the amount of principal of any original issue discount security that would be due and payable upon declaration of acceleration of the maturity thereof;

•

reduce the rate of or extend the time for payment of interest on any debt security of any series;

•

reduce the premium payable upon the redemption of any debt security;

•

make any debt security payable in currency other than that stated in the debt security;

impair the right to institute suit for the enforcement of any payment on or after the fixed maturity thereof or, in the case of redemption, on or after the redemption date; or

•

reduce the percentage of debt securities, the holders of which are required to consent to any such supplemental indenture or indentures.

A supplemental indenture that changes or eliminates any covenant, Event of Default 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 securities of any other series.

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

Information Concerning the Trustee

In case an Event of Default with respect to the securities of a series has occurred (that has not been cured or waived), the trustee shall exercise with respect to securities of that series such of the rights and powers vested in it by the indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. None of the provisions contained in the indenture shall require the trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or liability is not assured to it under the terms of the indenture or indemnity and security reasonably satisfactory to it against such risk is not assured to it.

The trustee may resign with respect to one or more series of debt securities by giving a written notice to Pentair Finance and to the holders of that series of debt securities. The holders of a majority in principal amount of the outstanding debt securities of a particular series may remove the trustee by notifying Pentair Finance and the trustee. Pentair Finance may remove the trustee if:

•

the trustee has or acquires a “conflicting interest,” within the meaning of Section 310(b) of the Trust Indenture Act, and fails to comply with the provisions of Section 310(b) of the Trust Indenture Act;

TABLE OF CONTENTS

•

the trustee fails to comply with the eligibility requirements provided in the indenture and fails to resign after written request therefor by Pentair Finance or by any such holder in accordance with the indenture; or

•

the trustee becomes incapable of acting, or is adjudged to be bankrupt or insolvent, or commences a voluntary bankruptcy proceeding, or a receiver of the trustee or of its property is appointed or consented to, or any public officer takes charge or control of the trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation.

If the trustee resigns or is removed or if the office of the trustee is otherwise vacant, Pentair Finance will appoint a successor trustee in accordance with the provisions of the indenture.

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.

Payment and Paying Agents

The interest installment on any security that is payable, and is punctually paid or duly provided for, on the fixed date on which an installment of interest with respect to securities of that series is due and payable, shall be paid to the person in whose name such security (or one or more predecessor securities) is registered at the close of business on the regular record date for such interest installment.

Pentair Finance, upon notice to the trustee, may appoint one or more paying agents, other than the trustee, for all or any series of the debt securities. The debt securities of a particular series will be surrendered for payment at the office of the paying agents designated by Pentair Finance. If Pentair Finance does not designate such an office, the corporate trust office of the trustee will serve as the office of the paying agent for such series. Pentair Finance or any of its subsidiaries may act as paying agent upon written notice to the trustee.

All funds paid by Pentair or Pentair Finance to a paying agent or the trustee for the payment of the principal of, premium, if any, or interest on the debt securities which remains unclaimed for at least one year after such principal, premium, if any, or interest has become due and payable will be repaid to Pentair or Pentair Finance, as the case may be, and the holder of the debt securities thereafter may look only to Pentair and Pentair Finance, as applicable, for payment thereof.

Governing Law

The indenture and any debt securities 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. The application of articles 470-3 to 470-19 of the Luxembourg law on commercial companies dated 10 August 1915, as amended, to the indenture and to any debt securities issued thereunder is excluded.

Satisfaction and Discharge of Indenture

The indenture shall cease to be of further effect with respect to a series of debt securities if, at any time:

(a) Pentair or Pentair Finance have delivered or have caused to be delivered to the trustee for cancellation all debt securities of a series theretofore authenticated, other than any debt securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in the indenture, and securities for whose payment funds or U.S. governmental obligations have theretofore been deposited in trust or segregated and held in trust by Pentair or Pentair Finance and thereupon repaid to Pentair or Pentair Finance or discharged from such trust, as provided in the indenture; or

Covenant Defeasance

Upon compliance with specified conditions, Pentair Finance and Pentair will not be required to comply with some covenants contained in the indenture and any applicable supplemental indenture, and any omission to comply with such covenants will not constitute a default or Event of Default relating to the applicable series of debt securities, or, if applicable, Pentair Finance’s and Pentair’s obligations with respect to the applicable series of debt securities will be discharged. These conditions are:

•

Pentair or Pentair Finance irrevocably deposits in trust with the trustee or, at the option of the trustee, with a trustee satisfactory to the trustee and Pentair or Pentair Finance, as the case may be, under the terms of an irrevocable trust agreement in form and substance satisfactory to the trustee, funds or U.S. governmental obligations or a combination thereof sufficient to pay principal of, premium, if any, and interest on the outstanding debt securities of such series to maturity or redemption, as the case may be, and to pay all other amounts payable by it under the indenture with respect to the outstanding debt securities of such series, provided that (A) the trustee of the irrevocable trust shall have been irrevocably instructed to pay such funds or the proceeds of such U.S. governmental obligations to the trustee and (B) the trustee shall have been irrevocably instructed to apply such funds or the proceeds of such U.S. governmental obligations to the payment of principal, premium, if any, and interest with respect to the debt securities of such series;

•

Pentair or Pentair Finance, as the case may be, shall have delivered to the trustee an opinion of counsel or a ruling received from the U.S. Internal Revenue Service to the effect that the holders of the debt securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of Pentair’s or Pentair Finance’s exercise of such defeasance or covenant defeasance, as the case may be, and will be subject to U.S. federal income tax in the same amount and in the same manner and at the same times as would have been the case if such election had not been exercised;

•

such defeasance or covenant defeasance shall not (i) cause the trustee to have a conflicting interest for purposes of the Trust Indenture Act with respect to any securities or (ii) result in the trust arising from such deposit to constitute, unless it is registered as such, a regulated investment company under the Investment Company Act of 1940, as amended; and

TABLE OF CONTENTS

•

such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on Pentair or Pentair Finance pursuant to the indenture.

Book-Entry, Delivery and Form

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depository identified in the applicable prospectus supplement. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. Unless otherwise provided in such prospectus supplement, debt securities that are represented by a global security will be issued in denominations of $2,000 or any integral multiple of $1,000 in excess thereof and will be issued in registered form only, without coupons.

We anticipate that any global securities will be deposited with, or on behalf of the Depository Trust Company (“DTC”), and that such global securities will be registered in the name of Cede & Co., DTC’s nominee. We further anticipate that the following provisions will apply to the depository arrangements with respect to any such global securities. Any additional or differing terms of the depository arrangements will be described in the prospectus supplement relating to a particular series of debt securities issued in the form of global securities.

Beneficial interests in the global securities will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct or indirect participants in DTC. Investors may elect to hold their interests in the global securities through either DTC (in the United States) or (in Europe) through Clearstream or through Euroclear. Investors may hold their interests in the global securities directly if they are participants of such systems, or indirectly through organizations that are participants in these systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective U.S. depositaries, which in turn will hold these interests in customers’ securities accounts in the depositaries’ names on the books of DTC. Beneficial interests in the global securities will be held in denominations of $2,000 and integral multiples of $1,000 in excess thereof. Except as set forth below, the global securities may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

Debt securities represented by a global security can be exchanged for definitive securities in registered form only if:

•

DTC notifies us that it is unwilling or unable to continue as depositary for that global security and Pentair Finance does not appoint a successor depositary within 90 days after receiving that notice;

•

at any time DTC ceases to be a clearing agency registered or in good standing under the Exchange Act or other applicable statute or regulation and Pentair Finance does not appoint a successor depositary within 90 days after becoming aware that DTC has ceased to be registered as a clearing agency; or

•

Pentair Finance determines that that global security will be exchangeable for definitive securities in registered form and notifies the trustee of its decision.

A global security that can be exchanged as described in the preceding sentence will be exchanged for definitive securities issued in authorized denominations in registered form for the same aggregate amount. The definitive securities will be registered in the names of the owners of the beneficial interests in the global security as directed by DTC.

We will make principal and interest payments on all debt securities represented by a global security to the paying agent which in turn will make payment to DTC or its nominee, as the case may be, as the sole registered owner and the sole holder of the debt securities represented by a global security for all purposes under the indenture. Accordingly, we, the trustee and any paying agent will have no responsibility or liability for:

•

any aspect of DTC’ s records relating to, or payments made on account of, beneficial ownership interests in a debt security represented by a global security; and

TABLE OF CONTENTS

•

any other aspect of the relationship between DTC and its participants or the relationship between those participants and the owners of beneficial interests in a global security held through those participants; or the maintenance, supervision or review of any of DTC’ s records relating to those beneficial ownership interests.

DTC has advised us that its current practice is to credit participants’ accounts on each payment date with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security as shown on DTC’s records, upon DTC’s receipt of funds and corresponding detail information. The underwriters or agents for the debt securities represented by a global security will initially designate the accounts to be credited. Payments by participants to owners of beneficial interests in a global security will be governed by standing instructions and customary practices, as is the case with securities held for customer accounts registered in “street name,” and will be the sole responsibility of those participants. Book-entry notes may be more difficult to pledge because of the lack of a physical note.

Pentair Finance is also required, pursuant to Luxembourg law, to maintain at its registered office a register of debt securities in registered form (registre des obligations nominatives) (the “Register”). Any registrar shall provide Pentair Finance, on any issue date and after any change made to any registrar’s register, with a copy of the relevant registrar’s register to enable Pentair Finance to maintain the Register. For purposes of Luxembourg law, ownership of the debt securities in registered form (obligations nominatives) will be evidenced through registration from time to time in the Register, and such registration will be a means of evidencing title to the debt securities in registered form. In case of discrepancies between the Register and any registrar’s register, the registrations in the Register shall prevail for purposes of Luxembourg law.

DTC

So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee, as the case may be, will be considered the sole owner and holder of the debt securities represented by that global security for all purposes of the debt securities. Owners of beneficial interests in the debt securities will not be entitled to have debt securities registered in their names, will not receive or be entitled to receive physical delivery of the debt securities in definitive form and will not be considered owners or holders of debt securities under the indenture. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of DTC and, if that person is not a DTC participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder of debt securities. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of the securities in certificated form. These laws may impair the ability to transfer beneficial interests in a global security. Beneficial owners may experience delays in receiving distributions on their debt securities since distributions will initially be made to DTC and must then be transferred through the chain of intermediaries to the beneficial owner’s account.

We understand that, under existing industry practices, if we request holders to take any action, or if an owner of a beneficial interest in a global security desires to take any action which a holder is entitled to take under the indenture, then DTC would authorize the participants holding the relevant beneficial interests to take that action and those participants would authorize the beneficial owners owning through such participants to take that action or would otherwise act upon the instructions of beneficial owners owning through them.

Beneficial interests in a global security will be shown on, and transfers of those ownership interests will be effected only through, records maintained by DTC and its participants for that global security. The conveyance of notices and other communications by DTC to its participants and by its participants to owners of beneficial interests in the debt securities will be governed by arrangements among them, subject to any statutory or regulatory requirements in effect.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Exchange Act.

DTC holds the securities of its participants and facilitates the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of

TABLE OF CONTENTS

its participants. The electronic book-entry system eliminates the need for physical certificates. DTC’s participants include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and certain other organizations, some of which, and/or their representatives, own DTC. Banks, brokers, dealers, trust companies and others that clear through, or maintain a custodial relationship with, a participant, either directly or indirectly, also have access to DTC’s book-entry system. The rules applicable to DTC and its participants are on file with the SEC.

DTC has advised us that the above information with respect to DTC has been provided to its participants and other members of the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

Clearstream

Clearstream has advised us that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Clearstream Participants in the United States are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant either directly or indirectly.

Distributions with respect to debt securities held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

Euroclear

Euroclear has advised us that it was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear performs various other services, including securities lending and borrowing and interacts with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A/N.V. (the “Euroclear Operator”) under contract with Euroclear plc, a U.K. corporation. All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not Euroclear plc. Euroclear plc establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator is a Belgian bank. As such it is regulated by the Belgian Banking and Finance Commission.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law, herein the Terms and Conditions. The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no record of or relationship with persons holding through Euroclear Participants. Distributions with respect to debt

TABLE OF CONTENTS

securities held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for Euroclear.

Euroclear has further advised us that investors that acquire, hold and transfer interests in the debt securities by book-entry through accounts with the Euroclear Operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global securities.

Global Clearance and Settlement Procedures

Initial settlement for the debt securities will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System. Secondary market trading between Clearstream Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream Participants or Euroclear Participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving debt securities through DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to their respective U.S. depositaries.

Because of time-zone differences, credits of debt securities received through Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such debt securities settled during such processing will be reported to the relevant Euroclear Participants or Clearstream Participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of debt securities by or through a Clearstream Participant or a Euroclear Participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

If the debt securities are cleared only through Euroclear and Clearstream (and not DTC), you will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices, and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers, and other institutions are open for business in the United States. In addition, because of time-zone differences, U.S. investors who hold their interests in the securities through these systems and wish to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, U.S. investors who wish to exercise rights that expire on a particular day may need to act before the expiration date.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of debt securities among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be modified or discontinued at any time. Neither we nor any paying agent will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective direct or indirect participants of their obligations under the rules and procedures governing their operations.

TABLE OF CONTENTS

DESCRIPTION OF ORDINARY SHARES

The following description of the material terms of Pentair’s ordinary shares is based on the provisions of the amended and restated memorandum and articles of association of Pentair (the “Constitution”). This description is not complete and is subject to the applicable provisions of the Companies Act 2014 of Ireland (as amended) (the “Companies Act”) and the Constitution, which is filed as an exhibit to the registration statement related to this prospectus. The transfer agent and registrar for Pentair’s ordinary shares is Computershare Inc. Pentair’s ordinary shares are listed on the New York Stock Exchange under the ticker symbol “PNR.”

Capital Structure

The current authorized share capital of Pentair is €40,000 and $4,260,000 divided into 40,000 ordinary shares with a nominal value of €1.00 per share and 426,000,000 ordinary shares with a nominal value of $0.01 per share. Pentair will disclose in an applicable prospectus supplement and/or offering material the number of shares of Pentair’s ordinary shares then outstanding. The authorized share capital includes 40,000 shares with a nominal value of €1 per share, which was required on incorporation in order to satisfy statutory requirements for all Irish public limited companies commencing operations.

Pentair may issue shares subject to the maximum authorized share capital contained in the Constitution. The authorized share capital may be increased by a resolution approved by a two-thirds majority of the votes of Pentair’s shareholders cast at a general meeting (referred to as a “variation resolution”) or reduced by a resolution approved by a simple majority of the votes of Pentair’s shareholders cast at a general meeting (referred to under Irish law as an “ordinary resolution”). The shares comprising the authorized share capital of Pentair may be divided into shares of such nominal value as the resolution shall prescribe. As a matter of Irish law, the directors of a company (or a duly authorized committee thereof) may cause the company to issue new ordinary shares without shareholder approval once authorized to do so by the constitution of the company or by an ordinary resolution adopted by the shareholders at a general meeting. In accordance with current customary practice in Ireland, Pentair sought, and received, shareholder approval at Pentair’s 2022 annual general meeting of shareholders to authorize the board of directors to issue up to a maximum of 33% of Pentair’s issued ordinary share capital as of March 18, 2022 (an aggregate nominal amount of $545,819 or 54,581,892 ordinary shares), for a period to expire 18 months from the approval, or November 17, 2023.

The rights and restrictions to which the ordinary shares are subject are prescribed in the Constitution.

Preemption Rights

Under Irish law certain statutory preemption rights apply automatically in favor of shareholders where shares are to be issued for cash. However, Pentair initially opted out of these preemption rights in the Constitution as permitted under Irish law. Because Irish law requires this opt-out to be renewed at least every five years by a resolution approved by not less than 75% of the votes of the shareholders of Pentair cast at a general meeting (referred to under Irish law as a “special resolution”), the Constitution provides that this opt-out must be so renewed. If the opt-out is not renewed, shares issued for cash must be offered to existing shareholders of Pentair on a pro rata basis to their existing shareholding before the shares can be issued to any new shareholders. The statutory preemption rights do not apply where shares are issued for non-cash consideration (such as in a stock-for-stock acquisition) and do not apply 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 where shares are issued pursuant to an employee option or similar equity plan. In accordance with current customary practice in Ireland, Pentair sought, and received, shareholder approval at Pentair’s 2022 annual general meeting of shareholders to authorize Pentair to opt out of preemption rights with respect to the allotment of equity securities up to a maximum of 10% of Pentair’s issued ordinary share capital as of March 18, 2022 (an aggregate nominal amount of $165,400 or 16,539,967 ordinary shares), provided that any amount above 5% of Pentair’s issued ordinary share capital as of March 18, 2022 (an aggregate nominal amount of $82,700 or 8,269,984 ordinary shares) is to be used only for the purpose of an acquisition or a specific capital investment. This approval will expire 18 months from the date of the approval, or November 17, 2023.

TABLE OF CONTENTS

Dividends

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

The determination as to whether or not Pentair has sufficient distributable reserves to fund a dividend must be made by reference to “relevant financial statements” of Pentair. The “relevant financial statements” will be either the last set of unconsolidated annual audited financial statements or other financial statements properly prepared in accordance with the Companies Act, which give a “true and fair view” of Pentair’s 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 Constitution authorizes the directors to declare dividends to the extent they appear justified by profits without shareholder approval. The Pentair board of directors may also recommend a dividend to be approved and declared by the Pentair shareholders at a general meeting. The Pentair board of directors may direct that the payment be made by distribution of assets, shares or cash and no dividend issued may exceed the amount recommended by the directors. Dividends may be declared and paid in the form of cash or non-cash assets and may be paid in U.S. dollars or any other currency. All holders of ordinary shares of Pentair will participate pro rata in respect of any dividend which may be declared in respect of ordinary shares by Pentair.

The directors of Pentair may deduct from any dividend payable to any shareholder any amounts payable by such shareholder to Pentair in relation to the ordinary shares of Pentair.

Bonus Shares

The Constitution authorizes the Pentair board of directors to capitalize any amount credited to any reserve, including undenominated capital, or credited to the profit and loss account, and use such amount for the issuance to shareholders of shares as fully paid bonus shares on the same basis of entitlement as would apply in respect of a dividend distribution.

Share Repurchases, Redemptions and Conversions

Overview

The Constitution provides that unless the Board specifically elects to treat such acquisition as a purchase for the purposes of the Companies Act, any ordinary shares which Pentair has agreed to acquire shall be deemed to be a redeemable share on, and from the time of, existence or creation of an agreement, transaction, or trade between Pentair and any third party pursuant to which Pentair acquires, or will acquire, ordinary shares, or an interest in ordinary shares, from such third party. Accordingly, for Irish company law purposes, the repurchase of ordinary shares by Pentair will technically be effected as a redemption of those shares as described below under “Repurchases and Redemptions by Pentair”. If the Constitution did not contain such provision, all repurchases by Pentair would be subject to many of the same rules that apply to purchases of Pentair ordinary shares by subsidiaries described below under “Purchases by Subsidiaries of Pentair” including the shareholder approval requirements described below and the requirement that any on-market purchases be effected on a “recognized stock exchange”. Neither Irish law nor any constituent document of Pentair places limitations on the right of nonresident or foreign owners to vote or hold Pentair ordinary shares. Except where otherwise noted, references elsewhere in this prospectus to repurchasing or buying back ordinary shares of Pentair refer to the redemption of ordinary shares by Pentair or the purchase of ordinary shares of Pentair by a subsidiary of Pentair, in each case in accordance with the Constitution and Irish company law as described below.

TABLE OF CONTENTS

Repurchases and Redemptions by Pentair

Under Irish law, a company may issue redeemable shares and redeem them out of distributable reserves or the proceeds of a new issue of shares for that purpose. Pentair may only issue redeemable shares if the nominal value of the issued share capital that is not redeemable is not less than 10% of the nominal value of the total issued share capital of Pentair. 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 canceled or held in treasury. Based on the provision of the Constitution described above, shareholder approval will not be required to redeem Pentair ordinary shares.

Pentair may also be given an additional general authority by its shareholders to purchase its own shares on-market which would take effect on the same terms and be subject to the same conditions as applicable to purchases by Pentair’s subsidiaries as described below.

Repurchased and redeemed shares may be canceled or held as treasury shares. The nominal value of treasury shares held by Pentair at any time must not exceed 10% of the nominal value of the issued share capital of Pentair. Pentair may not exercise any voting rights in respect of any shares held as treasury shares. Treasury shares may be canceled by Pentair or re-issued subject to certain conditions.

Purchases by Subsidiaries of Pentair

Under Irish law, an Irish or non-Irish subsidiary may purchase Pentair ordinary shares either as overseas market purchases or off-market purchases. For a subsidiary of Pentair to make overseas market purchases of Pentair ordinary shares, the shareholders of Pentair must provide general authorization for such purchase by way of ordinary resolution. However, as long as this general authority has been granted, no specific shareholder authority for a particular overseas market purchase by a subsidiary of Pentair ordinary shares is required. For an off-market purchase by a subsidiary of Pentair, the proposed purchase contract must be authorized by special resolution of the shareholders before the contract is entered into. The person whose Pentair ordinary shares are to be bought back cannot vote in favor of the special resolution and, for at least 21 days prior to the special resolution being passed, the purchase contract must be on display or must be available for inspection by shareholders at the registered office of Pentair.

In order for a subsidiary of Pentair to make an overseas market purchase of Pentair ordinary shares, such shares must be purchased on a “recognized stock exchange”. The New York Stock Exchange, on which the shares of Pentair are listed, is specified as a recognized stock exchange for this purpose by Irish company law.

The number of Pentair ordinary shares acquired and held by the subsidiaries of Pentair 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 nominal value of the issued share capital of Pentair. While a subsidiary holds Pentair ordinary shares, it cannot exercise any voting rights in respect of those shares. The acquisition of Pentair ordinary shares by a subsidiary must be funded out of distributable reserves of the subsidiary.

Lien on Shares, Calls on Shares and Forfeiture of Shares

The Constitution provides that Pentair will have a first and paramount lien on every share that is not a fully paid up share for all moneys payable at a fixed time or called in respect of that share, whether presently due or not in respect of such Pentair ordinary shares. Subject to the terms of their allotment, directors may call for any unpaid amounts in respect of any Pentair ordinary shares to be paid, and if payment is not made, the shares may be forfeited. These provisions are standard inclusions in the constitution of an Irish public company limited by shares such as Pentair and will only be applicable to Pentair ordinary shares that have not been fully paid up.

Consolidation and Division; Subdivision

Under the Constitution, Pentair may, by ordinary resolution, consolidate and divide all or any of its share capital into shares of larger nominal value than its existing shares or subdivide its shares into smaller amounts than is fixed by the Constitution.

TABLE OF CONTENTS

Reduction of Share Capital

Pentair may, by special resolution, reduce its authorized share capital in any way. Pentair also may, by special resolution and subject to confirmation by the Irish High Court, reduce or cancel its issued share capital in any manner permitted by the Companies Act.

Extraordinary General Meetings of Shareholders

Extraordinary general meetings of Pentair may be convened (i) by the Pentair board of directors, (ii) on requisition of the shareholders holding not less than 10% of the paid up share capital of Pentair carrying voting rights, or (iii) on requisition of Pentair’s auditors. Extraordinary general meetings are generally held for the purposes of approving shareholder resolutions as may be required from time to time. At any extraordinary general meeting only such business shall be conducted as is set forth in the notice thereof.

Voting

Each ordinary share is entitled to one vote on each matter properly brought before the shareholders. At any meeting of Pentair, all resolutions will be decided on a poll.

Treasury shares or Pentair ordinary shares that are held by subsidiaries of Pentair are not entitled to be voted at general meetings of shareholders.

Irish company law requires special resolutions of the shareholders at a general meeting to approve certain matters. Examples of matters requiring special resolutions include:

•

amending the Constitution;

•

approving a change of name of Pentair;

•

authorizing the entering into of a guarantee or provision of security in connection with a loan, quasi-loan or credit transaction to a director or connected person;

•

opting out of preemption rights on the issuance of new shares;

•

re-registration of Pentair from a public limited company to a private company;

•

variation of class rights attaching to classes of shares (where the Constitution does not provide otherwise);

•

purchase of Pentair shares off-market;

•

reduction of issued share capital;

•

sanctioning a compromise/scheme of arrangement;

•

resolving that Pentair be wound up by the Irish courts;

•

resolving in favor of a shareholders’ voluntary winding-up;

•

re-designation of shares into different share classes;

•

setting the re-issue price of treasury shares; and

•

a merger pursuant to the EU Cross-Border Merger Directives 2005/56/EC.

Variation of Rights Attaching to a Class or Series of Shares

Under the Constitution and the Companies Act, any variation of class rights attaching to the issued shares of Pentair must be approved in writing by holders of three-quarters of the issued shares in that class or with the sanction of a special resolution passed at a separate general meeting of the holders of the shares of that class, provided that, if the relevant class of holders has only one holder, that person present in person or by proxy shall constitute the necessary quorum.

Inspection of Books and Records

Under Irish law, shareholders have the right to: (i) receive a copy of the Constitution and any act of the Irish government which alters the Constitution; (ii) inspect and obtain copies of the minutes of general

TABLE OF CONTENTS

meetings and resolutions of Pentair; (iii) 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 Pentair; (iv) receive copies of statutory financial statements (or summary financial statements, where applicable) and directors’ and auditors’ reports which have previously been sent to shareholders prior to an annual general meeting; and (v) receive financial statements of any subsidiary of Pentair which have previously been sent to shareholders prior to an annual general meeting for the preceding ten years. The auditors of Pentair also have the right to inspect all books, records and vouchers of Pentair. The auditors’ report must be circulated to the shareholders with Pentair’s financial statements prepared in accordance with Irish law 21 days before the annual general meeting.

Acquisitions

An Irish public limited company may be acquired in a number of ways, including:

•

a court-approved scheme of arrangement under the Companies Act. A scheme of arrangement with shareholders requires a court order from the Irish High Court and the approval of a majority in number representing 75% in value of the shareholders present and voting in person or by proxy at a meeting called to approve the scheme;

•

through a tender or takeover offer by a third party for all of the ordinary shares of Pentair. Where the holders of 80% or more of Pentair’s ordinary shares have accepted an offer for their shares in Pentair, the remaining shareholders may also be statutorily required to transfer their shares. If the bidder does not exercise its “squeeze out” right, then the non-accepting shareholders also have a statutory right to require the bidder to acquire their shares on the same terms. If ordinary shares of Pentair were to be listed on the Irish Stock Exchange or another regulated stock exchange in the European Union, this threshold would be increased to 90%;

•

it is also possible for Pentair to be acquired by way of a transaction with an EU-incorporated company under Directive (EU) 2017/1132 of 14 June 2017 relating to certain aspects of company law. Such a transaction must be approved by a special resolution. If Pentair is being merged with another EU company under Directive (EU) 2017/1132 and the consideration payable to Pentair shareholders is not all in the form of cash, Pentair shareholders may be entitled to require their shares to be acquired at fair value; and

•

by way of merger with another Irish company under the Companies Act, which must be approved by a special resolution and by the Irish High Court.

Appraisal Rights

Generally, under Irish law, shareholders of an Irish company do not have appraisal rights. However, it does provide for dissenters’ rights in certain situations, as described below.

Under a tender or takeover offer, the bidder may require any remaining shareholders to transfer their shares on the terms of the offer (i.e., a “squeeze out”) if it has acquired, pursuant to the offer, not less than 80% of the target shares to which the offer relates (in the case of a company that is not listed on an European Economic Area regulated market). Dissenting shareholders have the right to apply to the Irish High Court for relief.

A scheme of arrangement which has been approved by the requisite shareholder majority and approved by the Irish High Court will be binding on all shareholders. Dissenting shareholders have the right to appear at the Irish High Court hearing and make representations in objection to the scheme.

Under the European Communities (Cross-Border Mergers) Regulations 2008, as amended, governing the merger of an Irish public limited company and a company incorporated in the European Economic Area (the European Economic Area includes all member states of the European Union and Norway, Iceland and Liechtenstein), a shareholder (i) who voted against the special resolution approving the merger or (ii) of a company in which 90% of the shares are held by the other party to the merger of the transferor company has the right to request that the company acquire its shares for cash.

TABLE OF CONTENTS

Similar rights apply in the case of a merger of an Irish public limited company into another company to which the provisions of the Companies Act apply.

Disclosure of Interests in Shares

Under the Companies Act, Pentair shareholders must notify Pentair (but not the public at large) if, as a result of a transaction, the shareholder will become interested in 3% or more of the shares of Pentair; or if as a result of a transaction a shareholder who was interested in more than 3% of the shares of Pentair ceases to be so interested. Where a shareholder is interested in more than 3% of the shares of Pentair, the shareholder must notify Pentair (but not the public at large) of 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. The relevant percentage figure is calculated by reference to the aggregate nominal value of the shares in which the shareholder is interested as a proportion of the entire nominal value of the issued share capital of Pentair (or any such class of share capital in issue). 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. Pentair must be notified within five business days of the transaction or alteration of the shareholder’s interests that gave rise to the notification requirement. If a shareholder fails to comply with these notification requirements, the shareholder’s rights in respect of any Pentair ordinary shares it holds will not be enforceable, either directly or indirectly, by action or legal proceeding. However, such person may apply to the court to have the rights attaching to such shares reinstated.

In addition to these disclosure requirements, Pentair, under the Companies Act, may, by notice in writing, require a person whom Pentair knows or has 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 Pentair’s relevant share capital to: (i) indicate whether or not it is the case and (ii) where such person holds or has during that time held an interest in the shares of Pentair, to provide additional information, including the person’s own past or present interests in shares of Pentair. If the recipient of the notice fails to respond within the reasonable time period specified in the notice, Pentair may apply to court for an order directing that the affected shares be subject to certain restrictions, as prescribed by the Companies Act, as follows:

•

any transfer of those shares, or in the case of unissued shares any transfer of the right to be issued with shares and any issue of shares, shall be void;

•

no voting rights shall be exercisable in respect of those shares;

•

no further shares shall be issued in right of those shares or in pursuance of any offer made to the holder of those shares; and

•

no payment shall be made of any sums due from Pentair on those shares, whether in respect of capital or otherwise.

The court may also order that shares subject to any of these restrictions be sold with the restrictions terminating upon the completion of the sale.

In the event Pentair is in an offer period pursuant to the Irish Takeover Rules (as defined below), accelerated disclosure provisions apply for persons holding an interest in Pentair securities of 1% or more.

Anti-Takeover Provisions

Irish Takeover Rules and Substantial Acquisition Rules

A transaction in which a third party seeks to acquire 30% or more of the voting rights of Pentair will be governed by the Irish Takeover Panel Act 1997 and the Irish Takeover Rules 2007 (as amended) (the “Irish Takeover Rules”) made thereunder and is regulated by the Irish Takeover Panel (the “Panel”). The “General Principles” of the Irish Takeover Rules and certain important aspects of the Irish Takeover Rules are described below.

TABLE OF CONTENTS

General Principles

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

•

in the event of an offer, all holders of security of the target company should be afforded equivalent treatment and, if a person acquires control of a company, the other holders of securities must be protected;

•

the holders of the securities in the target company must have sufficient time and information to enable them to reach a properly informed decision on the offer; where it advises the holders of securities, the board of the target company must give its views on the effects of implementation of the offer on employment, conditions of employment and the locations of the target company’s places of business;

•

the board of the target company must act in the interests of the company as a whole and must not deny the holders of securities the opportunity to decide on the merits of the offer;

•

false markets must not be created in the securities of the target company, the bidder or of any other company concerned by the offer in such a way that the rise or fall of the prices of the securities becomes artificial and the normal functioning of the markets is distorted;

•

a bidder must announce an offer only after ensuring that he or she can fulfill in full, any cash consideration, if such is offered, and after taking all reasonable measures to secure the implementation of any other type of consideration;

•

a target company must not be hindered in the conduct of its affairs for longer than is reasonable by an offer for its securities; and

•

a “substantial acquisition” of securities (whether such acquisition is to be effected by one transaction or a series of transactions) shall take place only at an acceptable speed and shall be subject to adequate and timely disclosure.

Mandatory Bid

Under certain circumstances, a person who acquires shares or other voting rights in Pentair may be required under the Takeover Rules to make a mandatory cash offer for the remaining outstanding shares in Pentair 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 an acquisition of shares would 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 Pentair, unless the Panel otherwise consents. An acquisition of shares by a person holding (together with its concert parties) shares representing between 30% and 50% of the voting rights in Pentair would also trigger the mandatory bid requirement if, after giving effect to the acquisition, the percentage of the voting rights held by that person (together with its concert parties) would increase 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

If a person makes a voluntary offer to acquire outstanding Pentair ordinary shares, the offer price must be no less than the highest price paid for Pentair ordinary shares by the bidder or its concert parties during the three-month period prior to the commencement of the offer period. The Panel has the power to extend the “look back” period to 12 months if the Panel, taking into account the General Principles, believes it is appropriate to do so.

If the bidder or any of its concert parties has acquired Pentair ordinary shares (i) during the period of 12 months prior to the commencement of the offer period which represent more than 10% of the total Pentair ordinary shares or (ii) at any time after the commencement of the offer period, the offer must be in cash (or accompanied by a full cash alternative) and the price per Pentair ordinary shares must not be less than

TABLE OF CONTENTS

the highest price paid by the bidder or its concert parties during, in the case of (i), the 12-month period prior to the commencement of the offer period and, in the case of (ii), the offer period. The Panel may apply this rule to a bidder who, together with its concert parties, has acquired less than 10% of the total Pentair ordinary shares in the 12-month period prior to the commencement of the offer period if the Panel, taking into account 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 Pentair. 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 Pentair 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 Pentair 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, the Pentair board of directors is not permitted to take any action which might frustrate an offer for the shares of Pentair once the Pentair board of directors has received an approach which may lead to an offer or has reason to believe an offer is imminent, subject to certain exceptions. Potentially frustrating actions such as (i) the issue of shares, options or convertible securities, (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 Pentair board of directors has reason to believe an offer is imminent. Exceptions to this prohibition are available where:

•

the action is approved by Pentair’s shareholders at a general meeting; or

•

the Panel has given its consent, where:

•

it is satisfied the action would not constitute frustrating action;

•

Pentair shareholders that hold 50% of the voting rights state in writing that they approve the proposed action and would vote in favor of it at a general meeting;

•

the action is taken in accordance with a contract entered into prior to the announcement of the offer; or

•

the decision to take such action was made before the announcement of the offer and either has been at least partially implemented or is in the ordinary course of business.

Certain other provisions of Irish law or the Constitution may be considered to have anti-takeover effects, including those described under the following captions in this “Description of Ordinary Shares”: “Capital Structure”, “Preemption Rights” and “Disclosure of Interests in Shares”.

Duration; Dissolution; Rights Upon Liquidation

Pentair’s duration will be unlimited. Pentair may be dissolved and wound up at any time by way of a shareholders’ voluntary winding up or a creditors’ winding up. In the case of a shareholders’ voluntary winding-up, a special resolution of shareholders is required. Pentair may also be dissolved by way of court order on the application of a creditor, or by the Companies Registration Office as an enforcement measure where Pentair has failed to file certain returns.

The rights of the shareholders to a return of Pentair’s assets on dissolution or winding up, following the settlement of all claims of creditors, may be prescribed in the Constitution. If the Constitution contains no specific provisions in respect of dissolution or winding up then, subject to the priorities of any creditors,

TABLE OF CONTENTS

the assets will be distributed to shareholders in proportion to the paid-up nominal value of the shares held. The Constitution provides that the ordinary shareholders of Pentair are entitled to participate pro rata in a winding up.

No Sinking Fund

The Pentair ordinary shares have no sinking fund provisions.

No Liability for Further Calls or Assessments

All of our issued ordinary shares are duly and validly issued and fully paid.

Transfer and Registration of Shares

The transfer agent for Pentair maintains the share register, registration in which is determinative of membership in Pentair. A shareholder of Pentair who holds shares beneficially is not the holder of record of such shares. Instead, the depository or other nominee is the holder of record of those shares. Accordingly, a transfer of shares from a person who holds such shares beneficially to a person who also holds such shares beneficially through a depository or other nominee is not registered in Pentair’s official share register, as the depository or other nominee remains the record holder of any such shares.

A written instrument of transfer is required under Irish law to register on Pentair’s 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 change in the depository or other nominee that is the record owner of the transferred shares. An instrument of transfer is also 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 Pentair’s official Irish share register. However, a shareholder who directly holds shares may transfer those shares into his or her own broker account (or vice versa) without giving rise to Irish stamp duty, provided that the shareholder has confirmed to Pentair’s transfer agent that there is no change in the ultimate beneficial ownership of the shares as a result of the transfer and the transfer is not made in contemplation of a sale of the shares.

Any transfer of Pentair ordinary shares that is subject to Irish stamp duty is not registered in the name of the buyer unless an instrument of transfer was duly stamped and provided to the transfer agent. The Constitution allows Pentair, in its absolute discretion, to create an instrument of transfer and pay (or procure the payment of) any stamp duty, which is the legal obligation of a buyer. In the event of any such payment, Pentair is (on behalf of itself or its affiliates) entitled to (i) seek reimbursement from the buyer or seller (at its discretion), (ii) set-off the amount of the stamp duty against future dividends payable to the buyer or seller (at its discretion) and (iii) claim a lien against the Pentair ordinary shares on which it has paid stamp duty. Parties to a share transfer may assume that any stamp duty arising in respect of a transaction in Pentair ordinary shares has been paid unless one or both of such parties is otherwise notified by Pentair.

The Constitution delegates to Pentair’s secretary or assistant secretary (or their nominees) 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 Pentair ordinary shares occurring through normal electronic systems, Pentair intends to regularly produce any required instruments of transfer in connection with any transactions for which it pays stamp duty (subject to the reimbursement and set-off rights described above). In the event that Pentair notifies one or both of the parties to a share transfer that it believes stamp duty is required to be paid in connection with the transfer and that it will not pay the stamp duty, the parties may either themselves arrange for the execution of the required instrument of transfer (and may request a form of instrument of transfer from Pentair for this purpose) or request that Pentair execute an instrument of transfer on behalf of the transferring party in a form determined by Pentair. 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 Pentair’s transfer agent, the buyer will be

TABLE OF CONTENTS

registered as the legal owner of the relevant shares on Pentair’s official Irish share register (subject to the matters described below).

The directors may suspend registration of transfers from time to time, not exceeding 30 days in aggregate each year.

TABLE OF CONTENTS

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts for the purchase or sale of our debt securities 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.

TABLE OF CONTENTS

DESCRIPTION OF WARRANTS

We may from time to time issue warrants to purchase our debt securities or equity securities or those of third parties. We may offer warrants separately or together with one or more additional warrants, debt securities 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 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:

•

the specific designation and aggregate number of, and the price at which we will issue, the warrants;

•

the currency or currency units in which the offering price, if any, and the exercise price are payable;

whether the warrants will be issued in fully registered form or bearer form, in definitive or global form or in any combination of these forms, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any security included in that unit;

•

any applicable material United States federal income tax consequences;

•

the identity of the warrant agent for the warrants and of any other depositaries, execution or paying agents, transfer agents, registrars or other agents;

TABLE OF CONTENTS

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 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 designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

•

any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units;

•

the terms of any agreements governing the units;

•

U.S. federal income tax considerations relevant to the units; and

•

whether the units will be issued in fully registered or global form.

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.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

We may sell the offered securities through agents, 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 will identify the specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation in a prospectus supplement.

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

•

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price.

•

Over-allotment involves sales by an underwriter of securities in excess of the number of securities an underwriter is obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of securities over-allotted by an underwriter is not greater than the number of securities that it may purchase pursuant to an over-allotment option. In a naked short position the number of securities involved is greater than the number of securities in an over-allotment option. An underwriter may close out any short position by either exercising its over-allotment option and/or purchasing securities in the open market.

•

Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions where there is an over-allotment option. In determining the source of securities to close out the short position, an underwriter will consider, among other things, the price of securities available for purchase in the open market as compared to the price at which they may purchase securities through the over-allotment option. If an underwriter sells more securities than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying securities in the open market. A naked short position is more likely to be created if an underwriter is concerned that there could be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.

•

Penalty bids permit representatives to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our securities or preventing or retarding a decline in the market price of the securities. As a result, the price of our 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.

We may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions from time to time. If the applicable prospectus supplement or free writing prospectus indicates, in connection with those derivative transactions, such third parties (or affiliates of such third parties) may sell securities covered by this prospectus and the applicable prospectus supplement or free writing prospectus, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may use securities pledged by us or borrowed from us or any securityholder or others to settle those sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivative transactions to close out any related open borrowings of securities. The third parties (or affiliates of such third parties) in such sale transactions

TABLE OF CONTENTS

by us will be underwriters and will be identified in an applicable prospectus supplement (or a post-effective amendment) or free writing prospectus. We may also sell securities under this prospectus upon the exercise of rights that may be issued to our securityholders.

We may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus and an applicable prospectus supplement or free writing prospectus. Such financial institution or third party may transfer its economic short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus.

Underwriters, dealers and agents may be entitled under agreements entered into with us to be indemnified by us against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribution by us to payments which they may be required to make. The terms and conditions of such indemnification will be described in an applicable prospectus supplement. Underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for, us in the ordinary course of business.

TABLE OF CONTENTS

ENFORCEMENT OF CIVIL LIABILITIES

Pentair Finance and Pentair will consent in the indenture to jurisdiction in the U.S. federal and state courts in the City of New York and to service of process in the City of New York in any legal suit, action or proceeding brought to enforce any rights under or with respect to the indenture, the notes and the guarantees. Any judgment against Pentair Finance or Pentair in respect of the indenture, the notes or the guarantees, including for civil liabilities under the U.S. federal securities laws, obtained in any U.S. federal or state court may have to be enforced in the courts of Luxembourg or Ireland. Investors should not assume that the courts of Luxembourg or Ireland would enforce judgments of U.S. courts obtained against Pentair Finance or Pentair, respectively, predicated upon the civil liability provisions of the U.S. federal securities laws or that such courts would enforce, in original actions, liabilities against Pentair Finance or Pentair predicated solely upon such laws.

Luxembourg

Pentair Finance is a private limited liability company organized under the laws of Luxembourg. Certain members of Pentair Finance’s board of managers are non-residents of the United States, and a substantial portion of Pentair Finance’s assets and the assets of its managers are located outside the United States. As a result, in a lawsuit based on the civil liability provisions of the U.S. federal or state securities laws, U.S. investors may find it difficult to:

•

effect service within the United States upon Pentair Finance or its managers located outside the United States;

•

enforce judgments obtained against those persons in U.S. courts or in courts in jurisdictions outside the United States; and

enforce against those persons in Luxembourg, whether in original actions or in actions for the enforcement of judgments of U.S. courts, civil liabilities based solely upon the U.S. federal or state securities laws.

Pentair Finance has been advised by its legal advisors that the United States and the Grand Duchy of Luxembourg are not currently bound by a treaty providing for reciprocal recognition and enforcement of judgments (other than arbitral awards) rendered in civil and commercial matters. According to such counsel, an enforceable judgment for the payment of monies rendered by any U.S. federal or state court based on civil liability, whether or not predicated solely upon the U.S. securities laws, would not directly be enforceable in Luxembourg. However, a party who received such favorable judgment in a U.S. court may initiate enforcement proceedings in Luxembourg (exequatur) by requesting enforcement of the U.S. judgment to the president of the District Court (Tribunal d’Arrondissement) pursuant to article 678 of the New Luxembourg Code of Civil Procedure and Luxembourg case law. The president of the District Court will authorize the enforcement in Luxembourg of the U.S. judgment if it is satisfied that all of the following conditions are met:

•

the U.S. judgment is enforceable (executoire) in the United States;

•

the jurisdictional ground of the U.S. court is founded according to Luxembourg conflict of jurisdiction rules and to the applicable domestic U.S. federal or state jurisdiction rules;

•

the U.S. court has applied to the dispute the substantive law which would have been designated by Luxembourg conflict of law rules;

•

the U.S. court has acted in accordance with its own procedural laws;

•

the U.S. judgment must not have violated the right of the defendant to present a defense;

•

the U.S. judgment must not have been rendered as a result of or in connection with an evasion of Luxembourg law (“fraude à la loi”); and

•

the U.S. judgment does not contravene Luxembourg international public policy. In practice, Luxembourg courts tend not to review the merits of a U.S. judgment.

TABLE OF CONTENTS

Ireland

Pentair is a public limited company organized under the laws of Ireland. A substantial portion of Pentair’s assets, which consist of shares in Pentair Finance, are located outside the United States, and the assets of its directors may be located outside of the United States. As a result, in a lawsuit based on the civil liability provisions of the U.S. federal or state securities laws, U.S. investors may find it difficult to:

•

effect service within the United States upon Pentair or its directors and officers located outside the United States;

•

enforce judgments obtained against Pentair or those persons in U.S. courts or in courts in jurisdictions outside the United States; and

•

bring an action in an Irish court to enforce against Pentair or those persons, whether in original actions or in actions for the enforcement of judgments of U.S. courts, civil liabilities based solely upon the U.S. federal or state securities laws.

Pentair has been advised by its legal advisors that a judgment for the payment of money rendered by a court in the United States based on civil liability would not be automatically enforceable in Ireland. There is no treaty between Ireland and the United States providing for the reciprocal enforcement of U.S. judgments. The following requirements must be met before the U.S. judgment will be deemed to be enforceable in Ireland:

•

the U.S. judgment must be for a definite sum;

•

the U.S. judgment must be final and conclusive;

•

the U.S. judgment must be provided by a court of competent jurisdiction;

•

the U.S. court must have had jurisdiction in relation to the particular defendant according to Irish conflict of law rules; and

•

jurisdiction must be obtained by the Irish courts over judgment debtors in enforcement proceedings by service in Ireland or outside Ireland in accordance with the applicable court rules in Ireland.

An Irish court will also exercise its right to refuse judgment if the U.S. judgment was obtained by fraud, if the judgment violated Irish public policy, if the judgment is in breach of natural justice or if it is irreconcilable with an earlier U.S. judgment.
