ITEM 1.01 Entry into a Material Definitive Agreement

On December 10, 2013, Pentair Ltd. (“Pentair”) entered into a Merger Agreement (the “Merger Agreement”) with Pentair plc, a newly-formed Irish public limited company and subsidiary of Pentair (“Pentair-Ireland”). Under the Merger Agreement, and subject to the conditions set forth in the Merger Agreement, Pentair will merge with and into Pentair-Ireland, with Pentair-Ireland being the surviving company (the “Merger”), thereby changing the jurisdiction of organization of the publicly-traded parent company from Switzerland to Ireland. Pentair shareholders will receive one ordinary share of Pentair-Ireland for each common share of Pentair held immediately prior to the Merger.

Upon completion of the Merger, Pentair-Ireland intends to manage its affairs so that it is centrally managed and controlled in the United Kingdom (the “U.K.”) and therefore have its tax residency in the U.K. Pentair-Ireland will continue to own and conduct the same businesses as Pentair owned and conducted prior to the Merger, except that Pentair-Ireland will replace Pentair as the publicly-traded parent company. Pentair-Ireland will remain subject to U.S. Securities and Exchange Commission (“SEC”) reporting requirements and the applicable corporate governance rules of the New York Stock Exchange (the “NYSE”).

The Merger is subject to Pentair shareholder approval of the Merger Agreement and certain other conditions. Pentair’s shareholders will be asked to vote to approve the Merger Agreement at an extraordinary general meeting of shareholders, which Pentair expects to be held during the second quarter of 2014.

The foregoing description of the Merger and related transactions does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement filed as Exhibit 2.1 and incorporated herein by reference.

This Merger Agreement (the “Agreement”) is made as of December 10, 2013 by and between Pentair Ltd. (“Pentair”), a Swiss company limited by shares (Aktiengesellschaft), with registered number CH-290.3.017.440-3 and whose registered office is at Freier Platz 10. CH-8200 Schaffhausen, Switzerland, and Pentair plc (“MergerCo”), a public liability company incorporated in Ireland with registered number 536025 and whose registered office is at Arthur Cox Building, Earlsfort Terrace, Dublin 2, Ireland.

WHEREAS:

1. MergerCo is 100% beneficially owned by Pentair.

2. The board of directors of Pentair has concluded to reorganise the Pentair group structure by having a new Irish holding company, MergerCo, serving as the publicly traded parent of the Pentair group of companies. To achieve this reorganisation, Pentair intends to merge with MergerCo on the terms and conditions set out in this Agreement.

3. As the merger results in MergerCo absorbing Pentair, at the direction of Pentair, the shareholders of Pentair (each a “Pentair Shareholder”) will receive, as merger consideration for each issued registered share (par value CHF 0.50 per share) in Pentair, including those held by Pentair Shares Ltd., being referred to herein as a “Pentair Share”), one ordinary share (par value US$0.01) credited as fully paid in MergerCo (each, a “MergerCo Share”).

4. The Parties have agreed that Pentair shall merge with MergerCo in accordance with the provisions of this Agreement and as stipulated by (and to the extent applicable to a cross-border merger) Art. 3 et seq. of the Swiss Act on Merger, Demerger, Transformation and Transfer of Assets (Fusionsgesetz) (Merger Act, “MerA”) and Art. 163b, 163c and 164 Swiss Private International Law Act (IPRG) (“PILA”) (emigration merger by absorption) as well as the applicable laws of Ireland. MergerCo shall be the surviving and Pentair the absorbed company, the latter being dissolved without liquidation.

5. The merger is intended to qualify as a reorganisation, within the meaning of Section 368(a)(1)(F) of the U.S. Internal Revenue Code of 1986, as amended (the “Tax Code”), and the rules and regulations promulgated thereunder (the “U.S. Treasury Regulations”), and this Agreement is intended to constitute a “plan of reorganisation” within the meaning of Section 368 of the Tax Code and related U.S. Treasury Regulations.

NOW IT IS AGREED as follows:

1. THE MERGER

1.1 Agreement to Merge by Absorption

The Parties hereby agree that:

(a) Pentair shall merge with MergerCo in accordance with the provisions of this Agreement and as stipulated by (to the extent applicable to a cross-border merger) Art. 3 et seq. MerA and Art. 163b, 163c and 164 PILA (emigration merger by absorption) as well as the applicable laws of Ireland (the “Merger”);

(b) MergerCo shall be the surviving and Pentair the absorbed company, the latter being dissolved without liquidation; and

1

(c) MergerCo shall:

(i) accept all of the assets of Pentair;

(ii) assume all of the liabilities of Pentair (with the effect that the obligees have a right to enforce such liabilities directly against MergerCo);

(iii) reconstitute its board of directors to match that of Pentair; and

(iv) issue MergerCo Shares to the Pentair Shareholders in accordance with the exchange ratio pursuant to Section 2 of this Agreement in consideration and acceptance of all the assets and liabilities of Pentair.

1.2 Merger Report

The board of directors of Pentair shall approve a merger report pursuant to Art. 14 MerA (the “Merger Report”) following the signing of this Agreement, as soon as practicable but no later than the date occurring 31 calendar days prior to the meeting of the Pentair Shareholders at which this Agreement will be submitted for shareholder approval (the “Pentair Shareholders’ Meeting”).

1.3 Merger Balance Sheet

The Merger shall take place on the basis of the audited, non-consolidated, stand-alone balance sheet of Pentair as of September 28, 2013 (the “Balance Sheet Date”) (the “Merger Balance Sheet”).

1.4 Balance Sheet Date

As from the Balance Sheet Date, all acts and operations of Pentair shall be deemed to be conducted for MergerCo’s account.

1.5 Audit of the Agreement, the Merger Report and the Merger Balance Sheet

The board of directors of Pentair shall appoint Deloitte AG, a licensed audit expert, to conduct the audit of this Agreement, the Merger Report and the Merger Balance Sheet pursuant to Art. 15 MerA.

1.6 Effective Time

The Merger, resulting in the transfer of any and all assets of Pentair to MergerCo and the assumption by MergerCo of any and all obligations and liabilities of Pentair, shall become legally effective on the date of the entry of the Merger in the daily ledger of the commercial register of the Canton of Schaffhausen, Switzerland (the “Commercial Register”), subject to approval by the Swiss Federal Commercial Register Office (EHRA) (the date and time of such entry hereinafter referred to as the “Effective Time”).

1.7 Transfer of Assets and Liabilities to MergerCo

(a) At the Effective Time, MergerCo shall accept the assignment, transfer, conveyance, assumption and delivery (as the case may be) of any and all of the rights, assets (including, for the avoidance of doubt, any and all goodwill, intellectual property rights, know-how, stock, property, records, cash, bank or brokerage accounts, artwork, contracts and the benefit of any claims or debts)

2

and liabilities (including, for the avoidance of doubt, any and all legal positions, obligations, claims, debts and environmental, health and safety, employer, contractual, financing or other liabilities, including contingent liabilities and guarantees) of Pentair.

(b) MergerCo particularly undertakes, for the benefit of each person to whom Pentair owes any obligation or has any liability, from and after the Effective Time, to accept, assume and agree to faithfully perform and fulfil such obligations and discharge such liabilities as if it originally owed or had them instead of Pentair. MergerCo accordingly agrees for the benefit of each such person that such person may enforce any such liability directly against MergerCo, without recourse to Pentair, on the same terms and to the same extent that such liability would have been enforceable by such person against Pentair had the Merger not been completed, regardless of where or against whom such liability is asserted or determined (including any liability arising out of claims made by Pentair’s or MergerCo’s respective shareholders, directors, officers, employees, agents, subsidiaries or affiliates) or whether asserted or determined prior to, on or after the Effective Time, and regardless of whether arising from or alleged to arise from negligence, recklessness, violation of the laws of any jurisdiction, fraud, misrepresentation or any other cause.

(c) As and from the Effective Time, MergerCo shall take the place, and assume control, of any claim made or proceedings threatened or issued by or against Pentair or where Pentair is otherwise a party or notice party to, whether asserted or determined prior to, on or after the Effective Time, and MergerCo shall seek to have its name substituted for that of Pentair in any proceedings ongoing before any court, arbitration or other judicial or administrative tribunal in any jurisdiction.

1.8 Completion

The transfer of all the assets and liabilities of Pentair (including, for the avoidance of doubt, any and all legal positions and obligations) to MergerCo shall be effected by implementing the completion measures herein agreed, all with legal effect as of the Effective Time.

2. MERGER CONSIDERATION

2.1 At the Effective Time and by virtue of the Merger, each holder of a Pentair Share, including Pentair Shares Ltd., shall receive one MergerCo Share in exchange for each Pentair Share held by such shareholder, and each such Pentair Share shall cease to be outstanding and shall be cancelled and shall cease to exist, and each holder of Pentair Shares shall thereafter cease to have any rights with respect to such Pentair Shares.

2.2 The Parties acknowledge and agree that as of the Effective Time, the MergerCo Shares issued to those holders of Pentair Shares shall all rank equally and have the same entitlement to dividend and any other shareholders’ rights, all in accordance with Irish law.

2.3 The Parties agree that on consummation of the Merger on the Effective Time, MergerCo shall acquire and cancel, for no consideration, all of the shares in the capital of MergerCo issued and outstanding as of immediately prior to the consummation of the Merger, being 40,000 ordinary shares of EUR 1.00 each in the capital of MergerCo (the “Initial Share Capital”).

Before the Effective Time, the MergerCo shareholders shall have authorised its directors to issue and allot, as per the Effective Time, one MergerCo Share for each Pentair Share in accordance with the exchange ratio pursuant to Section 2 of this Agreement in consideration for the transfer and assumption (as the case may be) of all of the assets and liabilities of Pentair and the cancellation of the Pentair Shares.

3.2 Settlement

At the Effective Time, MergerCo shall take any and all actions necessary or desirable to deliver the MergerCo Shares to holders of the Pentair Shares immediately prior to the Effective Time, including appointing a transfer agent selected by MergerCo (the “Transfer Agent”). Subject to, and with effect as from the Effective Time, the Transfer Agent or an affiliate of the Transfer Agent shall procure that the share register of MergerCo is written up as per the Effective Time showing that the Pentair Shareholders immediately prior to the Effective Time acquired MergerCo Shares in exchange for their Pentair Shares on a one-for-one basis as set out in Section 2.

3.3 Stock Plans

At the Effective Time, by virtue of the Merger, all other options or awards issued, or benefits available or based on Pentair Shares then outstanding (individually, an “Award” and collectively, the “Awards”) under the plans of Pentair (collectively, the “Stock Plans”) shall remain outstanding and, after the Effective Time, be deemed to provide for the issuance or purchase of, or otherwise relate to, the MergerCo Shares.

Each Award that is a stock option shall be assumed by MergerCo in such a manner that MergerCo would be a corporation “assuming a stock Option in a transaction to which Section 424(a) applies” within the meaning of Section 424 of the Tax Code, were Section 424 of the Tax Code applicable to such Award, without regard to the requirements of Treasury Regulation Section 1.424-1(a)(5)(iii), except to the extent such requirements specifically apply to such Award.

Each Award assumed by MergerCo shall be exercisable, issuable or available upon substantially the same terms and conditions as under the applicable Stock Plan and the applicable award agreement issued thereunder, except that upon the exercise, issuance or availability of such Awards, MergerCo Shares shall be issuable or available in lieu of Pentair Shares. The number of MergerCo Shares issuable or available upon the exercise or issuance of an Award immediately after the Effective Time and, if applicable, the exercise price of each such Award, shall be the number of shares and the exercise price as in effect for such Award immediately prior to the Effective Time. All Awards issued pursuant to the Stock Plans after the Effective Time shall entitle the holder thereof to purchase or receive MergerCo Shares in accordance with the terms of the Stock Plans.

3.4 Registration of Pentair Shareholders as MergerCo Shareholders

MergerCo shall, promptly following the Effective Time, register in its register of members as holders of the MergerCo Shares all former Pentair Shareholders who were registered in the share register of Pentair as at the Effective Time.

4.1 Adoption of Amended Articles of Association of MergerCo

At the Effective Time, MergerCo shall have adopted memorandum and articles of association setting out the rights and liabilities in respect of the MergerCo Shares provided that nothing in this Section 4.1 shall limit or fetter in any way the ability of MergerCo to amend, vary or substitute its memorandum and articles of association from time to time after the Effective Time.

At the Effective Time, the employee benefit and compensation plans and agreements of Pentair, together with any other plan and agreement of Pentair or its subsidiaries, as determined by the management of Pentair or MergerCo in its sole discretion, (together, the “Assumed Plans”) shall be assumed by and become plans and agreements of MergerCo. To the extent any Assumed Plan relates to Pentair Shares, then, as of the Effective Time, such plan shall be deemed to relate to MergerCo Shares. Any amendments deemed necessary or appropriate by Pentair and/or MergerCo to reflect the Merger and related transactions, including facilitating the assignment to MergerCo of one or more Assumed Plans, shall be adopted and entered into with respect to the Assumed Plans. The Pentair shareholder approval of this Agreement shall also be deemed to satisfy any requirement of shareholder approval of such amendments of the Assumed Plans and the Stock Plans and the assumption by MergerCo of the Assumed Plans and the Stock Plans and any Awards thereunder.

5.3 New Indemnity Agreements

MergerCo shall offer to enter into indemnity agreements (the “New Indemnity Agreements”) with each executive officer and director of MergerCo who, immediately prior to the Effective Time, is a party to an indemnity agreement with Pentair (each an “Old Indemnity Agreement”) and, to the extent permitted by Irish law, the terms and conditions of the New Indemnity Agreements shall be identical in all material respects (subject to such modifications or amendments as may be necessary or desirable to give effect to the primary contractual intention of the Old Indemnity Agreements) to those set forth in the Old Indemnity Agreements. Pentair shall procure that a subsidiary of Pentair shall offer to enter into indemnity agreements (the “Subsidiary Indemnity Agreements”) with each officer and director of MergerCo who immediately prior to the Effective Time is a party to an Old Indemnity Agreement such that the terms and conditions of the Subsidiary Indemnity Agreement when considered cumulatively with the terms and conditions of the New Indemnity Agreements shall be as extensive and provide at least the same level of indemnity protection as the Old Indemnity Agreements.
