REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustee and Participants of
Pentair, Inc. Retirement Savings and Stock Incentive Plan
5500 Wayzata Blvd, Suite 800
Golden Valley, Minnesota

Opinion on the Financial Statements
We have audited the accompanying statements of net assets available for benefits of the Pentair, Inc. Retirement Savings and Stock Incentive Plan (the “Plan”) as of December 31, 2017 and 2016, and the related statement of changes in net assets available for benefits for the year ended December 31, 2017, and the related notes (collectively, the “financial statements”). In our opinion, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2017 and 2016, and the changes in net assets available for benefits for the year ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statement. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Report on Supplemental Information
The supplemental schedules of (1) Assets (held at end of year) as of December 31, 2017, and (2) Delinquent Participant Contributions for the Year Ended December 31, 2017 have been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental schedules are the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental schedules reconcile to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedules. In forming our opinion on the supplemental schedules, we evaluated whether the supplemental schedules, including their form and content, are presented in compliance with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, such schedules are fairly stated, in all material respects, in relation to the financial statements as a whole.

1.
DESCRIPTION OF THE PLAN
The following description of the Pentair, Inc. Retirement Savings and Stock Incentive Plan (the "Plan") provides only general information. Participants should refer to the Plan document for a more complete description of the Plan.
General Information The Plan is a defined contribution profit-sharing plan with a cash or deferred arrangement described in Internal Revenue Code ("IRC") Section 401(k) and an employee stock ownership plan ("ESOP") component of the stock-bonus type. With certain exceptions, the Plan covers employees of Pentair, Inc. (the "Company") and its U.S. subsidiaries who have attained age 18, although such employees must have one year of service before becoming eligible for employer discretionary contributions. The Company is a subsidiary of Pentair plc and is the Plan sponsor as well as Plan administrator. Fidelity Management Trust Company ("Fidelity") is recordkeeper and trustee of the Plan, including the ESOP. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended.
On December 30, 2016, the ERICO Retirement Savings Plan ("ERICO Plan") was merged into the Plan. The circumstances set forth in Notes 1 and 2 to the financial statements included in Pentair, Inc.'s Annual Report on Form 11-K for the year ended Dec. 31, 2016, appropriately represent, in all material respects, the detailed disclosures discussing the merger of the ERICO Plan, and are incorporated herein by reference.
Participation Participation for regular full- and part-time employees may commence effective with the date of hire, provided that the employee is at least age 18, and provided that a non-regular employee must complete six months of service before becoming a participant. Participant contributions are subject to a maximum of 50% of pretax compensation and 15% of after-tax compensation for a combined limit of 65% of compensation. Employee contributions are also subject to the IRC 402(g) limitation of $18,000 for 2017 and 2016, respectively, provided that employees who will be age 50 or older are permitted to make additional catch-up contributions to the Plan up to the IRC limitation of $6,000 for 2017 and 2016, respectively.
The Plan has an automatic enrollment feature for new non-union employees at a rate of 3% with an automatic annual increase of 1% per year until the participant reaches a deferral rate of 10%. Employees can opt-out of automatic enrollment and automatic annual increase at any time.
Non-union matching contributions are 100% of the first 1% and 50% of the next 5% of compensation that is contributed by a participant and are made in the form of cash. Union matching contributions are made in accordance with the respective union contract agreements, with the majority of the union matching contributions being 50% of the first 5% of pretax participant contributions.
An employer discretionary contribution of 1.5% of annual base compensation was made at year-end for all non-union participants who had completed a year of eligible service during the Plan years 2017 and 2016. Discretionary contributions are made in the form of cash to purchase Pentair plc common stock. Discretionary contributions for union participants are made in accordance with the respective union contract agreements, which provide for contributions that range from 0% to 1.5% of annual based compensation.
Certain grandfathered groups of employees may receive an additional employer discretionary contribution of 1% to 5% in addition to the 1.5% employer discretionary contribution.
Participant Accounts Individual accounts are maintained for each Plan participant. Each participant's account is credited with the participant's contributions, the Company's matching contributions and allocations of Company discretionary contributions and Plan earnings, and charged with withdrawals and allocations of Plan losses and administrative expenses. Allocations are based on participant compensation or account balances, as defined in the Plan document. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.
Investments Participants direct the investment of their contributions into various investment options offered by the Plan. Company discretionary contributions are automatically invested in Pentair plc common stock. The Plan currently offers various investment alternatives to Plan participants, consisting of corporate stock, mutual funds and stable value funds. Investment management fees are charged against 401(k) trust earnings prior to the allocation of earnings.
Notes receivable from participants Loans for any reason are allowed under the Plan. The interest rate charged is prime rate plus 1% at the time funds are borrowed. The maximum maturity of the loans is five years (15 years for loans to

Notes to financial statements

purchase a primary residence). The minimum loan amount is $1,000, and the maximum is the lesser of 50% of the vested account balance, not including employer contributions, or $50,000. Due to transfers of notes receivable from participants related to plan mergers in the current and prior years, loans outstanding as of December 31, 2017 may bear interest at rates higher than the prime rate plus 1%, however, there are no loans outstanding with an original maturity greater than 15 years.
Vesting All elective deferral, after-tax, matching and discretionary contributions are immediately 100% vested.
Administrative Expenses Administrative expenses of the Plan are paid in part by the Plan sponsor and the participants as provided in the Plan document.
Payment of Benefits Upon severance from service for any reason, a participant may elect to receive a lump-sum amount equal to the value of the participant's vested interest in his or her account. Some participants can also elect annual installments over a term-certain period.
Withdrawals Hardship withdrawals are available for immediate and heavy financial need up to the amount of before-tax contributions, but not earnings. Hardship withdrawals can occur any time with a maximum of two per calendar year.
2.
SIGNIFICANT ACCOUNTING POLICIES
The financial statements of the Plan have been prepared on the accrual basis of accounting and in accordance with accounting principles generally accepted in the United States of America ("GAAP").
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and changes therein and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
The Plan provides various investment options to its participants, including corporate stock, mutual funds and stable value funds. Investment securities, in general, are exposed to various risks, such as interest rate risk, credit risk and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the financial statements.
The Plan's investments are stated at fair value, except for fully benefit-responsive investment contracts which are stated at contract value. Accounting guidance related to fair value measurements, which establishes a single authoritative definition of fair value, sets a framework for measuring fair value, and requires additional disclosures about fair value measurements (see Note 4). Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation and depreciation in the fair value of investments includes gains and losses in investments sold during the year as well as appreciation and depreciation of the investments held at year end.
The Managed Income Portfolio II Fund is valued using the net asset value ("NAV") per share. The fund's contract value as of December 31, 2017 was $113,939,948. The redemption frequency is daily. There is no redemption notice period for the individual participant level; however, there is up to a 12 month redemption notice period for the Plan level.
Notes receivable from participants are measured at their unpaid balance plus any accrued but unpaid interest. Delinquent participant loans are recorded as distributions based on the terms of the Plan document.
Benefit payments to participants are recorded upon distribution. There were no participants who have elected to withdraw from the Plan but had not yet been paid at December 31, 2017 and 2016.
3.
SYNTHETIC GUARANTEED INVESTMENT CONTRACT
The Plan provides participants a stable value investment option managed by Fidelity. The fund, the Managed Income Portfolio II Fund of the Fidelity Group for Employee Benefit Plans ("MIP II") includes synthetic guaranteed investment contracts (the "wrap contracts"), is a portfolio of financial instruments that are held in trust and owned by the plans participating in MIP II. The wrap contracts cover the underlying portfolio of financial instruments and require that all participant-initiated transactions be executed at contract value. Contract value represents contributions made to the fund, plus earnings, less participant withdrawals.
Wrap contracts accrue interest using a formula called the "crediting rate." Wrap contracts use the crediting rate formula to convert market value changes in the covered assets into income distributions in order to minimize the difference between

5

Notes to financial statements
As of December 31, 2017 and 2016, and for the year ended December 31, 2017


the market and contract value of the covered assets over time. Using the crediting rate formula, an estimated future market value is calculated by compounding the fund's current market value at the fund's current yield to maturity for a period equal to the fund's duration. The crediting rate is the discount rate that equates the estimated future market value with the fund's current contract value. Crediting rates are reset quarterly. The wrap contracts provide a guarantee that the crediting rate will not fall below 0%. The crediting rate is 1.77% for 2017.
The crediting rate, and hence the fund's return, may be affected by many factors, including purchases and redemptions by shareholders. The precise impact on the fund depends on whether the market value of the covered assets is higher or lower than the contract value of those assets. If the market value of the covered assets is higher than their contract value, the crediting rate will ordinarily be higher than the yield of the covered assets. Under these circumstances, cash from new investors will tend to lower the crediting rate and the fund's return, and redemptions by existing shareholders will tend to increase the crediting rate and the fund's return.
If the market value of the covered assets is lower than their contract value, the crediting rate will ordinarily be lower than the yield of the covered assets. When market value is lower than contract value, the fund will have, for example, less than $10 in cash and bonds for every $10 in NAV. Under these circumstances, cash from new investors will tend to increase the market value attributed to the covered assets and to increase the crediting rate and the fund's return. Redemptions by existing shareholders will have the opposite effect and will tend to reduce the market value attributed to remaining covered assets and to reduce the crediting rate and the fund's return. Generally, the market value of covered assets will tend to be higher than contract value after interest rates have fallen due to higher bond prices. Conversely, the market value of covered assets will tend to be lower than their contract value after interest rates have risen due to lower bond prices.
If the fund experiences significant redemptions when the market value is below the contract value, the fund's yield may be reduced significantly to a level that is not competitive with other investment options. This may result in additional redemptions, which would tend to lower the crediting rate further. If redemptions continue, the fund's yield could be reduced to zero. If redemptions continue thereafter, the fund might have insufficient assets to meet redemption requests, at which point the fund would require payments from the wrap issuer to pay further shareholder redemptions.
The fund and the wrap contracts purchased by the fund are designed to pay all participant-initiated transactions at contract value. Participant-initiated transactions are those transactions allowed by the Plan (typically this would include withdrawals for benefits, loans, or transfers to noncompeting funds within a plan). However, the wrap contracts limit the ability of the fund to transact at contract value upon the occurrence of certain events. These events include:
The Plan's failure to qualify under Section 401(a) or Section 401(k) of the IRC
The establishment of a defined contribution plan that competes with the Plan for employee contributions
Any substantive modification of the Plan or the administration of the Plan that is not consented to by the wrap issuer
Complete or partial termination of the Plan
Any change in law, regulation, or administrative ruling applicable to the Plan that could have a material adverse effect on the fund's cash flow
Merger or consolidation of the Plan into another plan; the transfer of Plan assets to another plan; or the sale, spin-off, or merger of a subsidiary or division of the Plan sponsor
Any communication given to participants by the Plan sponsor or any other Plan fiduciary that is designed to induce or influence participants not to invest in the fund or to transfer assets out of the fund
Exclusion of a group of previously eligible employees from eligibility in the Plan
Any early retirement program, group termination, group layoff, facility closing, or similar program
Any transfer of assets from the fund directly to a competing option
A wrap issuer may terminate a wrap contract at any time. In the event that the market value of the fund's covered assets is below its contract value at the time of such termination, Fidelity may elect to keep the wrap contract in place until such time as the market value of the fund's covered assets is equal to its contract value. A wrap issuer may also terminate a wrap contract if Fidelity's investment management authority over the fund is limited or terminated as well as if all of the terms of the wrap contract failed to be met. In the event that the market value of the fund's covered assets is below its contract value at the time of such termination, the terminating wrap provider would not be required to make a payment to the fund. The Plan sponsor does not believe that any events that may limit the ability of the Plan to transact at contract value are probable.

FAIR VALUE MEASUREMENTS
The Plan's estimates of fair value for financial assets are based on the framework established in the fair value accounting guidance. Fair value is the price that would be received by the Plan for an asset or paid by the Plan to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date in the Plan's principal or most advantageous market for the asset or liability. Fair value measurements are determined by maximizing the use of observable inputs and minimizing the use of unobservable inputs. The hierarchy places the highest priority on unadjusted quoted market prices in active markets for identical assets or liabilities (level 1 measurements) and gives the lowest priority to unobservable inputs (level 3 measurements). The three levels of inputs within the fair value hierarchy are defined as follows:
Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Plan has the ability to access.
Level 2: Significant other observable inputs other than level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
Level 3: Significant unobservable inputs that reflect the Plan's own assumptions about the assumptions that market participants would use in pricing an asset or liability.
In some cases, a valuation technique used to measure fair value may include inputs from multiple levels of the fair value hierarchy. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy.
Certain investments are measured at fair value on a recurring basis in the statements of net assets available for benefits. The following methods and assumptions were used to estimate the fair values:
Mutual funds, common stock and other investments These investments are classified as Level 1 and consist of various publicly-traded money market funds, mutual funds, common stock and other investments. Common stock is valued at quoted market prices. Shares of mutual funds are valued at quoted market prices, which represent the NAV of shares held by the Plan at period-end, and are actively traded.
Common/collective trusts These investments consist of various other collective investment trust funds. The underlying investments in these collective investment trust funds primarily include intermediate and long-term debt securities, corporate debt securities, equity securities and fixed income securities. The overall fair value of the common/collective trusts are valued at NAV, which is based on the fair value of the underlying securities owned by the fund and divided by the number of shares outstanding.

Certain investments that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented as investments in the statement of net assets available for benefits.
Transfers Between Levels The availability of observable market data is monitored to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period.
We evaluate the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total net assets available for benefits. For the years ended December 31, 2017 and 2016, there were no transfers between levels.
5.
FEDERAL INCOME TAX STATUS
The Internal Revenue Service ("IRS") has determined and informed the Company by a letter dated August 27, 2015, that the Plan was designed in accordance with applicable regulations of the IRC. The Plan has been amended since receiving the determination letter. However, the Company and Plan management believe that the Plan is currently designed and operated in compliance with the applicable requirements of the IRC, and the Plan continues to be tax-exempt. Therefore, no provision for income taxes has been included in the Plan's financial statements.

Notes to financial statements
As of December 31, 2017 and 2016, and for the year ended December 31, 2017


GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2014.
Prohibited Transactions — During 2017, the Company failed to remit timely certain employee contributions to the Plan aggregating to $12,026. The Company computed the lost earnings on these 2017 contributions, and their related matching contributions, and subsequently remitted the deposits and made a contribution for lost earnings to the Plan.
6.
EXEMPT PARTY-IN-INTEREST TRANSACTIONS
Certain Plan investments are shares of mutual funds managed by Fidelity. Fidelity is the trustee and recordkeeper as defined by the Plan. These transactions qualify as exempt party-in-interest transactions. Fees paid by the Plan for investment management services were included as a reduction of the return earned on each fund.
At December 31, 2017 and 2016, the Plan held 1,836,057 and 1,952,376 shares, respectively, of common stock of Pentair plc, the parent of the sponsoring employer, with a cost basis of $66,222,327 and $64,542,747, respectively. During the year ended December 31, 2017, the Plan recorded dividend income of $2,304,479 with respect to the common stock of Pentair plc.
7.
PLAN TERMINATION
Although it has not expressed any intention to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions set forth in ERISA.
