NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Background and Basis of Presentation

Background

Xylem Inc. (“Xylem” or the “Company”) is a leading equipment and service provider for water and wastewater applications with a broad portfolio of products and services addressing the full cycle of water, from collection, distribution and use to the return of water to the environment.

Xylem operates in three segments, Water Infrastructure, Applied Water and Measurement & Control Solutions. See Note 17, "Segment Information", to the condensed consolidated financial statements for further segment background information.

Except as otherwise indicated or unless the context otherwise requires, "Xylem," "we," "us," "our" and the "Company" refer to Xylem Inc. and its subsidiaries.

Basis of Presentation

The interim condensed consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions between our businesses have been eliminated.

The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair statement of the financial position and results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such SEC rules. We believe that the disclosures made are adequate to make the information presented not misleading. We consistently applied the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2020 ("2020 Annual Report") in preparing these unaudited condensed consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2020 Annual Report.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, post-retirement obligations and assets, revenue recognition, income taxes, valuation of intangible assets, goodwill and indefinite-lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates. The global outbreak of the novel coronavirus ("COVID-19") disease in March 2020, declared a pandemic by the World Health Organization, has created significant global volatility, uncertainty and economic disruption. The COVID-19 pandemic also has caused increased uncertainty in estimates and assumptions affecting the condensed consolidated financial statements. Actual results could differ from these estimates.

Our quarterly financial periods end on the Saturday closest to the last day of the calendar quarter, except for the fourth quarter which ends on December 31. For ease of presentation, the condensed consolidated financial statements included herein are described as ending on the last day of the calendar quarter.

(a)Emerging Markets revenue includes results from the following regions: Eastern Europe, the Middle East and Africa, Latin America and Asia Pacific (excluding Japan, Australia and New Zealand, which are presented in "Other")

Contract Balances

We receive payments from customers based on a billing schedule as established in our contracts. Contract assets relate to costs incurred to perform in advance of scheduled billings. Contract liabilities relate to payments received in advance of performance under the contracts. Changes in contract assets and liabilities are due to our performance under the contract.

9

The table below provides contract assets, contract liabilities, and significant changes in contract assets and liabilities:

(in millions)	Contract Assets (a)		Contract Liabilities
Balance at January 1, 2020	$	106	$	135
Additions, net	63		85

Other	—		(1)
Balance at June 30, 2021	$	121	$	171

(a)Excludes receivable balances which are disclosed on the balance sheet

Performance obligations

Delivery schedules vary from customer to customer based upon their requirements. Typically, large projects require longer lead production cycles and delays can occur from time to time. As of June 30, 2021, the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied for contracts with performance obligations, amount to $438 million. We expect to recognize the majority of revenue upon the completion of satisfying these performance obligations in the following 60 months. The Company elects to apply the practical expedient to exclude from this disclosure revenue related to performance obligations that are part of a contract whose original expected duration is less than one year.

Note 3. Restructuring and Asset Impairment Charges

Restructuring

From time to time, the Company will incur costs related to restructuring actions in order to optimize our cost base and more strategically position ourselves. During the three and six months ended June 30, 2021, we recognized restructuring charges of $3 million and $8 million, respectively, of which $2 million and $6 million relate to actions previously announced in 2020. These charges included reduction of headcount across all segments and asset impairments within our Measurement & Control Solutions segment.

In response to the changes in business and economic conditions arising as a result of the COVID-19 pandemic, in June 2020 management committed to a restructuring plan that includes actions across our businesses and functions globally. The plan is designed to support our long-term financial resilience, simplify our operations, strengthen our competitive positioning and better serve our customers. During the three and six months ended June 30, 2020, we recognized restructuring charges of $38 million and $40 million, respectively. These charges included reduction of headcount across all segments and asset impairments within our Measurement & Control Solutions segment.

The following table presents the components of restructuring expense and asset impairment charges:

	Three Months Ended				Six Months Ended
	June 30,				June 30,

The following table presents expected restructuring spend in 2021 and thereafter:

(in millions)	Water Infrastructure		Applied Water		Measurement & Control Solutions		Corporate		Total
Actions Commenced in 2021:
Total expected costs	$	5	$	—	$	—	$	—	$	5

Costs incurred during Q2 2021	2		—		—		—		2
Total expected costs remaining	$	2	$	3	$	2	$	2	$	9

The Water Infrastructure actions commenced in 2021 consist primarily of severance charges. These actions are expected to continue through the second quarter of 2022.

The Water Infrastructure, Applied Water, and Measurement & Control Solutions actions commenced in 2020 consist primarily of severance charges across segments and asset impairment charges in our Measurement & Control Solutions segment. These actions are expected to continue through the second quarter of 2022.

During the second quarter of 2020 the discontinuance of a product line resulted in $17 million of asset impairments, primarily related to customer relationships, trademarks and fixed assets within our Measurement & Control Solutions segment.

Asset Impairment

During the second quarter of 2020 we determined that internally developed in-process software within our Measurement & Control Solutions segment was impaired as a result of actions taken to prioritize strategic investments. Accordingly, we recognized an impairment charge of $10 million. Refer to Note 7, "Goodwill and Other Intangible Assets," for additional information.

Note 4. Income Taxes

Our quarterly provision for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items within periods presented. The comparison of our effective tax rate between periods is significantly impacted by the level and mix of earnings and losses by tax jurisdiction and discrete items.

The income tax provision for the three months ended June 30, 2021 was $25 million resulting in an effective tax rate of 18.5%, compared to a $4 million expense resulting in an effective tax rate of 10.9% for the same period in 2020. The income tax provision for the six months ended June 30, 2021 was $52 million resulting in an effective tax rate of 20.7%, compared to an $8 million expense resulting in an effective tax rate of 10.4% for the same period in 2020. The effective tax rate for the three and six month periods ended June 30, 2021 was lower than the U.S. federal statutory rate primarily due to favorable earnings mix, partially offset by the Global Intangible Low Taxed Income ("GILTI") inclusion. Additionally, the effective tax rate for the three and six month periods ended June 30, 2021 differ from the same periods in 2020 due to unfavorable earnings mix as compared to the prior year and favorable equity compensation deductions in the prior year. The effective tax rate for the six month period ended June 30, 2021 differs from the same period in 2020 due to the impact of tax settlements in the current period.

12

Unrecognized Tax Benefits

During 2019, Xylem’s Swedish subsidiary received a tax assessment for the 2013 tax year related to the tax treatment of an intercompany transfer of certain intellectual property that was made in connection with a reorganization of our European businesses. The assessment asserts an aggregate amount of approximately $80 million for tax, penalties and interest. Xylem filed an appeal with the Administrative Court of Stockholm. Management, in consultation with external legal advisors, believes it is more likely than not that Xylem will prevail on the proposed assessment and is vigorously defending our position through litigation. As of June 30, 2021, we have not recorded any unrecognized tax benefits related to this uncertain tax position.

Note 5. Earnings Per Share

The following is a reconciliation of the shares used in calculating basic and diluted net earnings per share:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2021		2020		2021		2020
Net income (in millions)	$	113	$	31	$	200	$	69
Shares (in thousands):
Weighted average common shares outstanding	180,072		179,933		180,162		180,043
Add: Participating securities (a)	34		32		24		29
Weighted average common shares outstanding — Basic	180,106		179,965		180,186		180,072
Plus incremental shares from assumed conversions: (b)
Dilutive effect of stock options	897		563		845		644
Dilutive effect of restricted stock units and performance share units	346		79		380		234
Weighted average common shares outstanding — Diluted	181,349		180,607		181,411		180,950
Basic earnings per share	$	0.63	$	0.17	$	1.11	$	0.38
Diluted earnings per share	$	0.62	$	0.17	$	1.10	$	0.38

(a)Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

(b)Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 13, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.

Note 8. Derivative Financial Instruments

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions, and we principally manage our exposures to these risks through management of our core business activities. Certain of our foreign operations expose us to fluctuations of foreign interest rates and exchange rates that may impact revenue, expenses, cash receipts, cash payments, and the value of our stockholders' equity. We enter into derivative financial instruments to protect the value or fix the amount of certain cash flows in terms of the functional currency of the business unit with that exposure and also reduce the volatility in stockholders' equity.

Cash Flow Hedges of Foreign Exchange Risk

We are exposed to fluctuations in various foreign currencies against our functional currencies. We use foreign currency derivatives, including currency forward agreements, to manage our exposure to fluctuations in the various exchange rates. Currency forward agreements involve fixing the foreign currency exchange rate for delivery of a specified amount of foreign currency on a specified date.

Certain business units with exposure to foreign currency exchange risks have designated certain currency forward agreements as cash flow hedges of forecasted intercompany inventory purchases and sales. Our principal currency exposures relate to the Euro, Swedish Krona, British Pound, Canadian Dollar, Polish Zloty and Australian Dollar. We had foreign exchange contracts with purchased notional amounts totaling $270 million and $0 million as of June 30, 2021 and December 31, 2020, respectively. As of June 30, 2021, our most significant foreign currency derivatives included contracts to sell U.S. Dollar and purchase Euro, purchase Swedish Krona and sell Euro, sell British Pound and purchase Euro, purchase Polish Zloty and sell Euro, purchase U.S. Dollar and sell Canadian Dollar, and to sell Canadian Dollar and purchase Euro. The purchased notional amounts associated with these currency derivatives are $97 million, $88 million, $36 million, $14 million, $13 million and $12 million, respectively.

Hedges of Net Investments in Foreign Operations

We are exposed to changes in foreign currencies impacting our net investments held in foreign subsidiaries.

Cross-Currency Swaps

Beginning in 2015, we entered into cross-currency swaps to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. During the second quarter of 2019 and third quarter of 2020 we entered into additional cross-currency swaps. The total notional amount of derivative instruments designated as net investment hedges was $1,208 million and $1,249 million as of June 30, 2021 and December 31, 2020, respectively.

Foreign Currency Denominated Debt

On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023. We designated the entirety of the outstanding balance, or $591 million and $610 million as of June 30, 2021 and December 31, 2020, respectively, net of unamortized discount, as a hedge of a net investment in certain foreign subsidiaries.

Senior Notes

On June 26, 2020, we issued 1.950% Senior Notes of $500 million aggregate principal amount due January 2028 (the “Senior Notes due 2028”) and 2.250% Senior Notes of $500 million aggregate principal amount due January 2031 (the “Senior Notes due 2031" and, together with the Senior Notes due 2028, the “Green Bond”).

The Green Bond includes covenants that restrict our ability, and the ability of our restricted subsidiaries, to incur debt secured by liens on certain property above a threshold, to engage in certain sale and leaseback transactions involving certain property above a threshold, and to consolidate or merge, or convey or transfer all or substantially all of our assets. We may redeem the Green Bond at any time, at our option, subject to certain conditions, at specified redemption prices, plus accrued and unpaid interest to the redemption date.

17

If a change of control triggering event (as defined in the applicable Green Bond indenture) occurs, we will be required to make an offer to purchase the notes at a price equal to 101% of their principal amount plus accrued and unpaid interest to the date of repurchase.

Interest on the Green Bond is payable on January 30 and July 30 of each year. As of June 30, 2021, we are in compliance with all covenants for the Green Bond.

On September 20, 2011, we issued 4.875% Senior Notes of $600 million aggregate principal amount due October 2021 (the "Senior Notes due 2021"). On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023 (the "Senior Notes due 2023"). On October 11, 2016, we issued 3.250% Senior Notes of $500 million aggregate principal amount due October 2026 (the “Senior Notes due 2026”) and 4.375% Senior Notes of $400 million aggregate principal amount due October 2046 (the “Senior Notes due 2046” and, together with the Senior Notes due 2021, the Senior Notes due 2023 and the Senior Notes due 2026, the “Senior Notes”).

The Senior Notes include covenants that restrict our ability, and the ability of our restricted subsidiaries, to incur debt secured by liens on certain property above a threshold, to engage in certain sale and leaseback transactions involving certain property above a threshold, and to consolidate or merge, or convey or transfer all or substantially all of our assets. We may redeem the Senior Notes, as applicable, in whole or in part, at any time at a redemption price equal to the principal amount of the Senior Notes to be redeemed, plus a make-whole premium. We may also redeem the Senior Notes in certain other circumstances, as set forth in the applicable Senior Notes indenture.

If a change of control triggering event (as defined in the applicable Senior Notes indenture) occurs, we will be required to make an offer to purchase the Senior Notes at a price equal to 101% of their principal amount plus accrued and unpaid interest to the date of repurchase.

Interest on the Senior Notes due 2021 is payable on April 1 and October 1 of each year. Interest on the Senior Notes due 2023 is payable on March 11 of each year. Interest on the Senior Notes due 2026 and the Senior Notes due 2046 is payable on May 1 and November 1 of each year.

Credit Facilities

2019 Five-Year Revolving Credit Facility

On March 5, 2019, Xylem entered into a Five-Year Revolving Credit Facility (the “2019 Credit Facility”) with Citibank, N.A., as Administrative Agent, and a syndicate of lenders. The 2019 Credit Facility provides for an aggregate principal amount of up to $800 million (available in U.S. Dollars and in Euros), with increases of up to $200 million for a maximum aggregate principal amount of $1 billion at the request of Xylem and with the consent of the institutions providing such increased commitments.

Interest on all loans under the 2019 Credit Facility is payable either quarterly or at the expiration of any LIBOR or EURIBOR interest period applicable thereto. Borrowings accrue interest at a rate equal to, at Xylem's election, a base rate or an adjusted LIBOR or EURIBOR rate plus an applicable margin. The 2019 Credit Facility includes customary provisions for implementation of replacement rates for LIBOR-based and EURIBOR-based loans. The 2019 Credit Facility also includes a pricing grid that determines the applicable margin based on Xylem's credit rating, with a further adjustment depending on Xylem's annual Sustainalytics Environmental, Social and Governance ("ESG") score, determined based on the methodology in effect as of March 5, 2019. Xylem will also pay quarterly fees to each lender for such lender’s commitment to lend accruing on such commitment at a rate based on our credit rating, whether such commitment is used or unused, as well as a quarterly letter of credit fee accruing on the letter of credit exposure of such lender during the preceding quarter at a rate based on the credit rating of Xylem (as adjusted for the ESG score). 

The 2019 Credit Facility requires that Xylem maintain a consolidated total debt to consolidated EBITDA ratio (or maximum leverage ratio), which will be based on the last four fiscal quarters; and in addition contains a number of customary covenants, including limitations on the incurrence of secured debt and debt of subsidiaries, liens, sale and lease-back transactions, mergers, consolidations, liquidations, dissolutions and sales of assets. The 2019 Credit Facility also contains customary events of default. Finally, Xylem has the ability to designate subsidiaries that can borrow under the 2019 Credit Facility, subject to certain requirements and conditions set forth in the 2019 Credit Facility. 

18

On June 22, 2020, Xylem entered into Amendment No. 1 to the 2019 Credit Facility (the "Amendment") which modified the financial covenant from a test based on the maximum leverage ratio (defined as consolidated total debt to consolidated EBITDA) to a test based on the net leverage ratio (defined as consolidated total debt less unrestricted cash and cash equivalents to consolidated EBITDA). This modification is effective through the quarter ending September 30, 2021, after which the covenant will revert back to the prior maximum leverage ratio test. The Amendment also restricted stock repurchases until March 31, 2021, except for shares of common stock in an amount not to exceed the number of shares issued after the date of the Amendment, subject to customary exceptions. As of June 30, 2021, the 2019 Credit Facility was undrawn and we are in compliance with all revolver covenants. 

Commercial Paper

U.S. Dollar Commercial Paper Program

Our U.S. Dollar commercial paper program generally serves as a means of short-term funding with a $600 million maximum issuing balance and a combined limit of $800 million inclusive of the 2019 Credit Facility. As of June 30, 2021 and December 31, 2020, none of the Company's $600 million U.S. Dollar commercial paper program was outstanding. We have the ability to continue borrowing under this program going forward in future periods.

Euro Commercial Paper Program

On June 3, 2019, Xylem entered into a Euro commercial paper program with ING Bank N.V., as administrative agent, and a syndicate of dealers. The Euro commercial paper program provides for a maximum issuing balance of up to €500 million (approximately $592 million) which may be denominated in a variety of currencies. The maximum issuing balance may be increased in accordance with the Dealer Agreement. As of June 30, 2021 and December 31, 2020, none of the Company's Euro commercial paper program was outstanding. We have the ability to continue borrowing under this program going forward in future periods.

The total net periodic benefit cost for other post-retirement employee benefit plans was less than $1 million, including net credits recognized into other comprehensive income of less than $1 million, for both the three and six months ended June 30, 2021 and 2020, respectively.

19

We contributed $12 million and $16 million to our defined benefit plans during the six months ended June 30, 2021 and 2020, respectively. Additional contributions ranging between approximately $7 million and $15 million are expected to be made during the remainder of 2021.

During the first quarter of 2020, the Company purchased a bulk annuity policy with an insurance company for its largest defined benefit plan in the U.K., as a plan asset, to facilitate the termination and buy-out of the plan. The bulk annuity fully insures the benefits payable to the participants of the plan until a full buy-out of the plan can be executed, which is expected to occur in 2022. Included in the Company's six months ended June 30, 2020 contributions is $5 million paid to meet the shortfall between the cost of the bulk annuity policy and the plan assets.

Stock Option Grants

The following is a summary of the changes in outstanding stock options for the six months ended June 30, 2021:

	Share units (in thousands)	Weighted Average Exercise Price / Share		Weighted  Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2021	1,961	$	56.66	6.4
Granted	259	102.31
Exercised	(135)	58.39
Forfeited and expired	(22)	83.88

Options exercisable at June 30, 2021	1,409	$	51.45	5.0	$	98
Vested and expected to vest as of June 30, 2021	1,987	$	60.98	6.2	$	119

The total intrinsic value of options exercised (which is the amount by which the stock price exceeded the exercise price of the options on the date of exercise) during the six months ended June 30, 2021 was $7.1 million.

Stock Option Fair Value

The fair value of each option grant was estimated on the date of grant using the binomial lattice pricing model which incorporates multiple and variable assumptions over time, including assumptions such as employee exercise patterns, stock price volatility and changes in dividends. The following are weighted-average assumptions for 2021 grants:

Volatility	26.30		%
Risk-free interest rate	0.86		%
Dividend yield	1.10		%
Expected term (in years)	5.7
Weighted-average fair value / share	$	23.20

Expected volatility is calculated based on an analysis of historic volatility measures for Xylem. We use historical data to estimate option exercise and employee termination behavior within the valuation model. Employee groups and option characteristics are considered separately for valuation purposes. The expected term represents an estimate of the period of time options are expected to remain outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of option grant.

Restricted Stock Unit Grants

The following is a summary of restricted stock unit activity for the six months ended June 30, 2021. The fair value of the restricted share unit awards is determined using the closing price of our common stock on date of grant:

Outstanding at January 1, 2021	537	$	74.62
Granted	213	103.36
Vested	(233)	74.47
Forfeited	(15)	85.91
Outstanding at June 30, 2021	502	$	86.47

The fair value of TSR performance share units was calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The following are weighted-average assumptions for 2021 grants:

Volatility	33.5	%
Risk-free interest rate	0.24	%

ESG Performance Share Unit Grants

During the first quarter of 2021, we issued a special grant of less than 0.1 million ESG performance share units. The shares will vest after five years based on our performance against certain of the Company's 2025 sustainability goals.

Note 14. Capital Stock

For the three and six months ended June 30, 2021, the Company repurchased less than 0.1 million shares of common stock for $1 million and approximately 0.7 million shares of common stock for $68 million, respectively. For the three and six months ended June 30, 2020, the Company repurchased less than 0.1 million shares of common stock for less than $1 million and approximately 0.8 million shares of common stock for $60 million, respectively.

repurchases in relation to settlement of employee tax withholding obligations due as a result of the vesting of restricted stock units. The details of repurchases by each program are as follows:

On August 24, 2015, our Board of Directors authorized the repurchase of up to $500 million in shares with no expiration date. The program's objective is to deploy our capital in a manner that benefits our shareholders and maintains our focus on growth. There were no shares repurchased under the program for the three months ended June 30, 2021. For the six months ended June 30, 2021, we repurchased approximately 0.6 million shares for $60 million. There were no shares repurchased under the program for the three months ended June 30, 2020. For the six months ended June 30, 2020, we repurchased approximately 0.7 million shares for $50 million. There are up to $228 million in shares that may still be purchased under this plan as of June 30, 2021.

Aside from the aforementioned repurchase program, we repurchased less than 0.1 million shares and approximately 0.1 million shares for $1 million and $8 million for the three and six months ended June 30, 2021, respectively, in relation to settlement of employee tax withholding obligations due as a result of the vesting of restricted stock units. Likewise, we repurchased less than 0.1 million shares and approximately 0.1 million shares for less than $1 million and $10 million for the three and six months ended June 30, 2020, respectively.

Note 16. Commitments and Contingencies

Legal Proceedings

From time to time, we are involved in legal and regulatory proceedings that are incidental to the operation of our businesses (or the business operations of previously-owned entities). These proceedings may seek remedies relating to matters including environmental, tax, intellectual property, acquisitions or divestitures, product liability, property damage, personal injury, privacy, employment, labor and pension, government contract issues and commercial or contractual disputes.

From time to time, claims may be asserted against Xylem alleging injury caused by any of our products resulting from asbestos exposure. We believe there are numerous legal defenses available for such claims and would defend ourselves vigorously. Pursuant to the Distribution Agreement among ITT Corporation (now ITT LLC; acquired by Delticus HoldCo, L.P., a portfolio company of Warburg Pincus LLC, on July 1, 2021), Exelis (acquired by Harris Corporation, now L3Harris Technologies, Inc.) and Xylem, ITT LLC has an obligation to indemnify, defend and hold Xylem harmless for asbestos product liability matters, including settlements, judgments, and legal defense costs associated with all pending and future claims that may arise from past sales of ITT’s legacy products. We believe ITT LLC remains a substantial entity with sufficient financial resources to honor its obligations to us.

25

See Note 4, "Income Taxes", of our condensed consolidated financial statements for a description of a pending tax litigation matter.

Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on present information, including our assessment of the merits of the particular claims, we do not believe it is reasonably possible that any asserted or unasserted legal claims or proceedings, individually or in aggregate, will have a material adverse effect on our results of operations, or financial condition. We have estimated and accrued $5 million and $6 million as of June 30, 2021 and December 31, 2020, respectively, for these general legal matters.

Indemnifications

As part of our 2011 spin-off from our former parent, ITT Corporation (now ITT LLC; acquired by Delticus HoldCo, L.P., a portfolio company of Warburg Pincus LLC, on July 1, 2021), Exelis Inc. (acquired by Harris Corporation, now L3Harris Technologies, Inc.) and Xylem will indemnify, defend and hold harmless each of the other parties with respect to such parties’ assumed or retained liabilities under the Distribution Agreement and breaches of the Distribution Agreement or related spin agreements. ITT LLC's indemnification obligations include asserted and unasserted asbestos and silica liability claims that relate to the presence or alleged presence of asbestos or silica in products manufactured, repaired or sold prior to October 31, 2011, the Distribution Date, subject to limited exceptions with respect to certain employee claims, or in the structure or material of any building or facility, subject to exceptions with respect to employee claims relating to Xylem buildings or facilities. The indemnification associated with pending and future asbestos claims does not expire. Xylem has not recorded a liability for material matters for which we expect to be indemnified by the former parent or Exelis Inc. through the Distribution Agreement and we are not aware of any claims or other circumstances that would give rise to material payments from us under such indemnifications.

Guarantees

We obtain certain stand-by letters of credit, bank guarantees, surety bonds and insurance letters of credit from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance-related requirements. As of June 30, 2021 and December 31, 2020, the amount of surety bonds, bank guarantees, insurance letters of credit and stand-by letters of credit was $410 million and $378 million, respectively.

Environmental

In the ordinary course of business, we are subject to federal, state, local, and foreign environmental laws and regulations. We are responsible, or are alleged to be responsible, for ongoing environmental investigation and remediation of sites in various countries. These sites are in various stages of investigation and/or remediation and in many of these proceedings our liability is considered de minimis. We have received notification from the U.S. Environmental Protection Agency, and from similar state and foreign environmental agencies, that a number of sites formerly or currently owned and/or operated by Xylem or for which we are responsible under the Distribution Agreement, and other properties or water supplies that may be or have been impacted from those operations, contain disposed or recycled materials or wastes and require environmental investigation and/or remediation. These sites include instances where we have been identified as a potentially responsible party under federal and state environmental laws and regulations.

Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. Our accrued liabilities for these environmental matters represent our best estimates related to the investigation and remediation of environmental media such as water, soil, soil vapor, air and structures, as well as related legal fees. These estimates, and related accruals, are reviewed quarterly and updated for progress of investigation and remediation efforts and changes in facts and legal circumstances. Liabilities for these environmental expenditures are recorded on an undiscounted basis. We have estimated and accrued $3 million as of both June 30, 2021 and December 31, 2020 for environmental matters.

It is difficult to estimate the final costs of investigation and remediation due to various factors, including incomplete information regarding particular sites and other potentially responsible parties, uncertainty regarding the extent of investigation or remediation and our share, if any, of liability for such conditions, the selection of alternative remedial approaches, and changes in environmental standards and regulatory requirements. We believe the total amount accrued is reasonable based on existing facts and circumstances.

26

Warranties

We warrant numerous products, the terms of which vary widely. In general, we warrant products against defect and specific non-performance. The table below provides changes in the combined current and non-current product warranty accruals over each period:

(in millions)	2021		2020

Overview

Xylem is a leading global water technology company. We design, manufacture and service highly engineered products and solutions ranging across a wide variety of critical applications in utility, industrial, residential and commercial building services settings. Our broad portfolio of solutions addresses customer needs across the water cycle, from the delivery, measurement and use of drinking water to the collection, test, treatment and analysis of wastewater to the return of water to the environment. Our product and service offerings are organized into three reportable segments that are aligned around the critical market applications they provide: Water Infrastructure, Applied Water and Measurement & Control Solutions.

•Water Infrastructure serves the water infrastructure sector with pump systems that transport water from aquifers, lakes, rivers and seas; with filtration, ultraviolet and ozone systems that provide treatment, making the water fit to use; and pumping solutions that move the wastewater and storm water to treatment facilities where our mixers, biological treatment, monitoring and control systems provide the primary functions in the treatment process. We also provide sales and rental of specialty dewatering pumps and related equipment and services. Additionally, our offerings use monitoring and control, smart and connected technologies to allow for remote monitoring of performance and enable products to self-optimize pump operations maximizing energy efficiency and minimizing unplanned downtime and maintenance for our customers. In the Water Infrastructure segment, we provide the majority of our sales directly to customers along with strong applications expertise, while the remaining amount is through distribution partners.

•Applied Water serves the water usage applications sector with water pressure boosting systems for heating, ventilation and air conditioning, and for fire protection systems to the residential and commercial building services markets. In addition, our pumps, heat exchangers and controls provide cooling to power plants and manufacturing facilities, circulation for food and beverage processing, as well as boosting systems for agricultural irrigation. In the Applied Water segment, we provide the majority of our sales through long-standing relationships with many of the leading independent distributors in the markets we serve, with the remainder going directly to customers.

•Measurement & Control Solutions primarily serves the utility infrastructure solutions and services sector by delivering communications, smart metering, measurement and control technologies and critical infrastructure technologies that allow customers to more effectively use their distribution networks for the delivery, monitoring and control of critical resources such as water, electricity and natural gas. We also provide analytical instrumentation used to measure and analyze water quality, flow and level in clean water, wastewater, surface water and coastal environments. Additionally, we offer software and services including cloud-based analytics, remote monitoring and data management, leak detection, condition assessment, asset management and pressure monitoring solutions. In the Measurement & Control Solutions segment, we generate our sales through a combination of long-standing relationships with leading distributors and dedicated channel partners as well as direct sales depending on the regional availability of distribution channels and the type of product.

COVID-19 Pandemic Update

Depending on the severity, magnitude and duration of the COVID-19 pandemic and its economic consequences, we anticipate that it will become more difficult to distinguish specific aspects of our operational and financial performance that are most directly related to the pandemic from those more broadly influenced by ongoing macroeconomic, market and industry dynamics that may be, to varying degrees, related to the pandemic and its consequences.

The COVID-19 pandemic as well as broader market dynamics have adversely affected, and are expected to continue to adversely affect, our supply chains. We have experienced, and expect to continue experiencing, shortages in the supply of components, parts and raw materials, and, in some cases, unpredictable interruptions with our external suppliers in 2021. We have also experienced increased logistics costs related to the current global capacity shortages. We continue to enhance our supplier pulsing and redundancy to help mitigate these challenges. Additionally, we have in the past and may continue to take measures with respect to buffer stock or use of alternative suppliers to mitigate the impacts of freight and logistics delays and bolster our access to raw materials and components. If these shortages and interruptions are sustained, or if additional interruptions occur, they could have a negative impact on our results of operations. Our current overall operating capacity approximates normal levels globally.

30

Xylem Watermark, our corporate social responsibility program, continues to support our communities in addressing the challenges posed by this global pandemic through its partnership with Americares and UNICEF, as well as the Partner Community Grants program and matching donations program for employees and partners, and other philanthropic commitments.

Xylem continues to focus on the health and safety of our employees, working with our customers to help them minimize potential disruptions and positively impact our communities. Our support pay program for employees impacted by COVID-19 will remain in place into the fourth quarter of 2021 and is evaluated for continuation, as necessary.

Many of our offices globally remain in a substantially remote work from home status and our COVID-19 Response Team applies a set of Xylem "Return to Workplace" health and safety guidelines for remote workers to return to our facilities.

We continue to assess the evolving nature of the pandemic and its possible implications to our business, employees, supply chain, customers and communities, and to take actions in an effort to mitigate adverse consequences.

Risk related to the impact of COVID-19 as well as our supply chain are described in further detail under "Item 1A. Risk Factors" in the Company's 2020 Annual Report.

Executive Summary

Xylem reported revenue for the second quarter of 2021 of $1,351 million, an increase of 16.5% compared to $1,160 million reported in the second quarter of 2020. On a constant currency basis, revenue increased by $125 million, or 10.8%, driven by organic revenue growth across all segments and in all end markets.

We generated operating income of $160 million (margin of 11.8%) during the second quarter of 2021, as compared to $54 million (margin of 4.7%) in 2020. Operating income in the second quarter of 2021 benefited from a decrease in restructuring and realignment costs of $37 million as compared to the second quarter of 2020 and special charges of $11 million incurred during 2020 that did not recur. Excluding the impact of these items, adjusted operating income was $166 million (adjusted margin of 12.3%) during the second quarter of 2021 as compared to $108 million (adjusted margin of 9.3%) in 2020. The increase in adjusted operating margin was primarily due to cost reductions from our productivity, restructuring and other cost saving initiatives and favorable volume, impacted by COVID-19 recovery. These impacts were partially offset by cost inflation and increased spending on strategic investments.

Additional financial highlights for the quarter ended June 30, 2021 include the following:

•Orders of $1,660 million, up 34.7% from $1,232 million in the prior year, and up 28.8% on an organic basis.

•Earnings per share of $0.62, up 264.7% when compared to the prior year ($0.66, up 65.0% on an adjusted basis).

•Net income as a percent of revenue of 8.4%, up 570 basis points compared to 2.7% in the prior year. EBITDA margin of 16.2%, up 650 basis points when compared to 9.7% in the prior year (17.3%, up 200 basis points on an adjusted basis)

•Net cash flow provided by operating activities of $206 million for the six months ended June 30, 2021, an increase of $27 million from cash provided in the same period of the prior year. Free cash flow was $126 million, up $42 million from the prior year.

Key Performance Indicators and Non-GAAP Measures

Management reviews key performance indicators including revenue, gross margins, segment operating income and operating income margins, orders growth, working capital and backlog, among others. In addition, we consider certain non-GAAP (or "adjusted") measures to be useful to management and investors evaluating our operating performance for the periods presented, and to provide a tool for evaluating our ongoing operations, liquidity and management of assets. This information can assist investors in assessing our financial performance and measures our ability to generate capital for deployment among competing strategic alternatives and initiatives, including, but not limited to, dividends, acquisitions, share repurchases and debt repayment. Excluding revenue, Xylem provides guidance only on a non-GAAP basis due to the inherent difficulty in forecasting certain amounts that would be included in GAAP earnings, such as discrete tax items, without unreasonable effort. These adjusted metrics are consistent with how management views our business and are used to make financial, operating and planning decisions. These metrics, however, are not measures of financial performance under GAAP and should not be considered a substitute for revenue, operating income, net income, earnings per share (basic and diluted) or net cash from operating activities as determined in accordance with GAAP. We consider the following items to represent the non-GAAP measures we consider to be key performance indicators, as well as the related reconciling items to the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measures may not be comparable to similarly-titled measures reported by other companies.

•"organic revenue" and "organic orders" defined as revenue and orders, respectively, excluding the impact of fluctuations in foreign currency translation and contributions from acquisitions and divestitures. Divestitures include sales or discontinuance of insignificant portions of our business that did not meet the criteria for classification as a discontinued operation. The period-over-period change resulting from foreign currency translation impacts is determined by translating current period and prior period activity using the same currency conversion rate.

•"constant currency" defined as financial results adjusted for foreign currency translation impacts by translating current period and prior period activity using the same currency conversion rate. This approach is used for countries whose functional currency is not the U.S. Dollar.

•"adjusted net income" and "adjusted earnings per share" defined as net income and earnings per share, respectively, adjusted to exclude restructuring and realignment costs, special charges, gain or loss from sale of businesses and tax-related special items, as applicable. A reconciliation of adjusted net income and adjusted earnings per share is provided below.

2021 Outlook

We anticipate total revenue growth in the range of 8% to 10% in 2021, with organic revenue growth anticipated to be in the range of 6% to 8%. The following is a summary of our organic revenue outlook by end markets:

•Utilities revenue increased by approximately 5% organically through the first half of the year driven by strength in western Europe and the emerging markets, partially offset by weakness in North America. For 2021, we expect organic revenue growth in the mid to high-single-digit range with continued resilience on the wastewater side, as utilities remain focused on mission-critical applications and anticipate modest growth on a global basis through the year. The timing of large clean water utility project deployments has been impacted by the global shortage of electronic components, which we expect to continue throughout the remainder of 2021. We anticipate that these deployments will ramp up when supply constraints ease based on our strong backlog position and orders momentum. Additionally, we expect healthy momentum in the test and treatment markets globally and increased demand for our smart water solution and digital offerings.

•Industrial revenue increased by approximately 15% organically through the first half of the year driven by strength across all major geographic regions. For 2021, we expect organic revenue growth in the high-single-digit range as activity across all segments rebounds globally and our dewatering business continues to recover, especially in the emerging markets, as demand increases and site access restrictions continue to ease. We anticipate growth in during the second half of the year led by North America, with growth in emerging markets and western Europe as well.

•In the commercial markets, organic revenue growth was approximately 8% through the first half of the year driven by strength in western Europe, North America and the emerging markets. For 2021, we expect organic revenue growth in the mid to high-single-digit range. We expect replacement business in the U.S. to be stable during the year and anticipate continued healthy activity in Europe. We expect new construction activity in North America to be soft, however we are optimistic that conditions will begin to recover late in the year.

•In the residential markets, organic revenue growth was approximately 30% through the first half of the year driven by strength in the emerging markets, North America and western Europe. This market is primarily driven by replacement revenue serviced through our distribution network. For 2021, we expect organic revenue growth in the low-teens, driven by healthy demand activity from increased residential users in the U.S. and Europe. Additionally, we anticipate strong demand in China for secondary water supply product applications.

We will continue to strategically execute restructuring and realignment actions in an effort to optimize our cost structure, improve our operational efficiency and effectiveness, strengthen our competitive positioning and better serve our customers. During 2021, we expect to incur between $30 million and $40 million in restructuring and realignment costs. We expect to realize between $35 million and $40 million of net savings in 2021, consisting of between $33 million and $35 million of incremental net savings from restructuring and realignment actions initiated in 2020, and between $2 million and $5 million of net savings from the restructuring, realignment and other structural cost actions initiated during this year.

Revenue

Revenue generated during the three and six months ended June 30, 2021 was $1,351 million and $2,607 million, reflecting increases of $191 million, or 16.5%, and $324 million, or 14.2%, respectively, compared to the same prior year periods. On a constant currency basis, revenue grew 10.8% and 9.4% for the three and six months ended June 30, 2021. The increases on a constant currency basis were driven by organic revenue growth of $128 million and $219 million, respectively, reflecting strong organic growth across all major geographic regions and segments.

The following table illustrates the impact from organic growth, recent divestitures, and foreign currency translation in relation to revenue during the three and six months ended June 30, 2021:

Water Infrastructure

Water Infrastructure revenue increased $68 million, or 13.6%, for the second quarter of 2021 (6.4% increase on a constant currency basis) as compared to the prior year. Revenue benefited from $36 million of foreign currency translation, with the change at constant currency coming entirely from organic growth of $32 million. Organic growth for the quarter was driven by strength in the industrial end market, particularly across the emerging markets and, to a lesser extent, in western Europe. Organic growth for the quarter was also driven by strength in the utility end market, primarily in western Europe where we saw strong demand in utilities' operational spending coupled with recovery from prior year COVID-19 impacts. Organic growth in the utility end market was marginally offset by declines in North America during the quarter.

From an application perspective, organic revenue growth for the second quarter was driven by our transport application. The transport application had strong revenue growth in the emerging markets, where the dewatering business in Latin America and Africa benefited from strong market conditions in mining during the quarter and Asia Pacific had strong revenue growth during the quarter, and in western Europe, where we had strong industrial and utility demand, positively impacted by COVID-19 recovery. Organic revenue growth from our transport application was partially offset by a modest decline in the treatment application, driven by the timing of project deliveries in the U.S. as compared to the prior year.

For the six months ended June 30, 2021, revenue increased $139 million, or 14.8% (8.4% increase on a constant currency basis) as compared to the prior year. Revenue benefited from $60 million of foreign currency translation during the six month period, with the change at constant currency coming entirely from organic growth of $79 million. Organic growth during the year was driven by strength in the both the utility and industrial end markets. Strength in the utility end market was led by western Europe, where utilities' operational spending continues to be strong, and in the emerging markets, where China benefited from healthy order intake coming into the year. Organic growth in the industrial end market was particularly strong across the emerging markets, which included growth from the COVID-19 recovery in Latin America and healthy order intake in China and Africa, and in western Europe.

From an application perspective, organic revenue growth during the six month period was primarily driven by our transport application. The transport application was driven by strong revenue growth across the emerging markets, where we benefited from healthy order intake in Asia Pacific and Africa and a favorable prior year comparison in Latin America, as well as growth from the COVID-19 recovery in western Europe. Organic revenue from our treatment application also contributed to the segment's growth during the period, driven by strength in the emerging markets, particularly in China, which was partially offset by the timing of project deliveries in the U.S. during the year.

Applied Water

Applied Water revenue increased $77 million, or 22.8%, for the second quarter of 2021 (17.5% increase on a constant currency basis) as compared to the prior year. Revenue benefited from $18 million of foreign currency translation, with the change at constant currency coming entirely from organic growth of $59 million. Organic growth for the quarter was driven by strength in every end market and across all major geographic regions, with particular strength in North America and western Europe.

36

From an application perspective, organic revenue growth in the second quarter was led by strength in the industrial water application which was primarily driven by market growth across the emerging markets, strong order intake in North America, with particular strength in specialty flow control applications (marine and food & beverage), and market recovery in western Europe, where the industry was more significantly impacted by the COVID-19 pandemic in the prior year. The residential building services application also had strong organic growth, primarily driven by western Europe, as market conditions recover from the COVID-19 pandemic, strength in North America, where we benefited from healthy backlog execution, and the emerging markets, specifically driven by strong second water supply business in China. The commercial building services application also contributed organic growth during the quarter, primarily driven by strength in the U.S. and western Europe, where the industry was more significantly impacted by the COVID-19 pandemic in the prior year.

For the six months ended June 30, 2021, revenue increased $132 million, or 19.6% (15.3% increase on a constant currency basis) as compared to the prior year. Revenue benefited from $29 million of foreign currency translation during the six month period, with the change at constant currency coming entirely from organic growth of $103 million. Organic growth during the period was driven by strength in every end market and across all major geographic regions.

From an application perspective, organic revenue growth during the six month period was led by strength in the industrial water application, which was primarily driven by market growth in the emerging markets, particularly in Asia Pacific where the industry was more significantly impacted by the COVID-19 pandemic in the first half of the prior year, strong order intake in North America and western Europe, reflecting recovery from the COVID-19 pandemic during the second quarter of the year. The residential building services application revenue also had strong organic growth during the first half of the year, primarily driven by the emerging markets where we experienced strong second water supply business and a favorable prior year comparison in China, as markets conditions recover from the COVID-19 pandemic. Strength in North America also contributed to the growth in the residential building services application, as we benefited from healthy backlog execution coming into the year, and market growth in western Europe during the period. The commercial building services application contributed organic growth during the first half of the year, primarily driven by strength in western Europe, North America and the emerging markets, particularly Asia Pacific.

Measurement & Control Solutions

Measurement & Control Solutions revenue increased $46 million, or 14.3%, for the second quarter of 2021 (10.6% increase on a constant currency basis) as compared to the prior year. Revenue benefited from $12 million of foreign currency translation, with the change at constant currency driven by organic growth of $37 million which was partially offset by reduced revenue related to divestiture impacts of $3 million. Organic revenue growth during the quarter was driven by strength in both the utility and industrial end markets and across all major geographic regions.

In order to simplify and focus the application discussion, beginning with the first quarter of 2021, we are aggregating the test application into the water application and the software as a service and other application into the water and energy applications, as applicable, as both of these sub-applications provide products and services to the broader, ultimate applications of water and energy. From an application perspective, organic revenue growth was driven by the timing of project deployments in the water application, coupled with COVID-19 recovery in the U.S. and western Europe during the quarter. The energy application experienced a modest decrease during the quarter, primarily driven project timing and supply chain constraints in the U.S.

For the six months ended June 30, 2021, revenue increased $53 million, or 7.9% (4.8% increase on a constant currency basis) as compared to the prior year. Revenue benefited from $21 million of foreign currency translation during the six month period, with the change at constant currency driven by organic growth of $37 million which was partially offset by reduced revenue related to divestiture impacts of $5 million. Organic revenue growth during the period was driven by strength in both end markets and across all major geographic regions, particularly in western Europe.

From an application perspective, organic revenue growth during the period was driven by the water application, particularly in the U.S. and western Europe, where regions benefited from a favorable prior year comparison during the period coupled with strong backlog execution. This organic revenue growth was partially offset by a decline in the energy application during the period driven by the gas business, where large project deployments in the U.S. during the prior year did not repeat and we experienced project delays driven by the COVID-19 pandemic during the year.

Orders / Backlog

An order represents a legally enforceable, written document that includes the scope of work or services to be performed or equipment to be supplied to a customer, the corresponding price and the expected delivery date for the applicable products or services to be provided. An order often takes the form of a customer purchase order or a signed quote from a Xylem business. Orders received during the second quarter of 2021 were $1,660 million, an increase of $428 million, or 34.7%, over the prior year (28.7% increase on a constant currency basis). Orders received during the six months ended June 30, 2021 were $3,198 million, an increase of $705 million, or 28.3%, over the prior year (23.3% increase on a constant currency basis). Order intake benefited from $74 million and $123 million of foreign currency translation for the three and six months ended June 30, 2021, respectively. The increase on a constant currency basis was primarily driven by organic order growth of $355 million and $590 million for the three and six months ended June 30, 2021, respectively.

Water Infrastructure

Water Infrastructure segment orders increased $41 million, or 6.9%, to $639 million (flat on a constant currency basis) for the second quarter of 2021 as compared to the prior year. Order growth for the quarter benefited from $41 million of foreign currency translation. Organic orders remained essentially flat during the quarter as strength in the treatment application, which was driven by strong order intake across all major geographies, was offset by decline in the transport application, which included a significant project order of greater than $100 million in India during the second quarter of 2020 that did not recur. Excluding the impact of the significant India order in 2020, the transport application had organic order growth driven by healthy market conditions in western Europe and North America during the quarter, including order growth in the dewatering business.

38

For the six months ended June 30, 2021, orders increased $138 million, or 12.4%, to $1,250 million (6.3% increase on a constant currency basis) as compared to the same prior year period. Order growth during the period benefited from $68 million of foreign currency translation. The order increase on a constant currency basis consisted primarily of organic order growth in the treatment application. Organic growth in the treatment application was driven by strength in North America, the emerging markets, particularly in China, and western Europe. Organic orders for the transport application also increased during the period, primarily driven by healthy market conditions in western Europe and North America which were partially offset by weakness in the emerging markets, where we had a significant project order of greater than $100 million in India during the second quarter of 2020 which more than offset strength in Latin America and Africa during period.

Applied Water

Applied Water segment orders increased $160 million, or 49.1%, to $486 million (42.9% increase on a constant currency basis) for the second quarter of 2021 as compared to the prior year. Order growth for the quarter benefited from $20 million of foreign currency translation. The order increase on a constant currency basis was driven by organic order growth across all end markets, primarily in the U.S., where we benefited from strong demand recovery, amplified by longer lead times for delivering product, and to a lesser extent, in western Europe and the emerging markets.

For the six months ended June 30, 2021, orders increased $265 million, or 38.0%, to $963 million (33.2% increase on a constant currency basis) as compared to the same prior year period. Order growth during the period benefited from $33 million of foreign currency translation. The order increase on a constant currency basis was driven by organic order growth across all end markets during the first half of the year, primarily in the U.S., where we benefited from strong demand, amplified by early ordering to mitigate longer lead times, and to a lesser extent, in western Europe and the emerging markets, particularly in China where order intake was weakened by COVID-19 impacts in the prior year.

Measurement & Control Solutions

Measurement & Control Solutions segment orders increased $227 million, or 73.7%, to $535 million (69.5% increase on a constant currency basis) for the second quarter of 2021 as compared to the prior year. Order growth for the quarter benefited from $13 million of foreign currency translation. The order increase on a constant currency basis consisted almost entirely of organic order growth of $215 million, or 69.8%. Organic order growth was led by the water application, which experienced strong order intake in the U.S., amplified by increased ordering due to component shortages, and benefited from a favorable comparison, driven by COVID-19 recovery, as well as strength in western Europe. Order intake in the energy application also grew organically during the quarter, primarily in North America where the gas business benefited from a favorable comparison, driven by COVID-19 recovery, coupled with project related ordering in the electric business during the quarter.

For the six months ended June 30, 2021, orders increased $302 million, or 44.2%, to $985 million (41.0% increase on a constant currency basis) as compared to the same prior year period. Order growth during the period benefited from $22 million of foreign currency translation. The order increase on a constant currency basis included organic order growth of $288 million, or 42.2%, which was partially offset by a $8 million reduction in orders related to divestiture impacts during the period. Organic order growth was led by the water application, which was driven by strong order intake in the U.S., amplified by increased ordering due to component shortages, and in western Europe, coupled with a favorable comparison, driven by COVID-19 recovery. Order intake in the energy application also grew organically during the first half of the year, primarily driven by large projects in North America.

Backlog

Backlog includes orders on hand as well as contractual customer agreements at the end of the period. Delivery schedules vary from customer to customer based on their requirements. Annual or multi-year contracts are subject to rescheduling and cancellation by customers due to the long-term nature of the contracts. As such, beginning total backlog, plus orders, minus revenues, will not equal ending total backlog due to contract adjustments, foreign currency fluctuations, and other factors. Typically, large projects require longer lead production cycles and deployment schedules and delays occur from time to time. Total backlog was $2,779 million at June 30, 2021, an increase of $766 million or 38.1%, as compared to June 30, 2020 backlog of $2,013 million, and an increase of $655 million or 30.8%, as compared to December 31, 2020 backlog of $2,124 million driven by the significant increase in orders in the year. We anticipate that approximately 50% of the backlog at June 30,

39

2021 will be recognized as revenue in the remainder of 2021. There were no significant order cancellations during the quarter.

Gross Margin

Gross margin as a percentage of revenue increased 110 and 180 basis points to 38.5% and 38.7% for the three and six months ended June 30, 2021, as compared to 37.4% and 36.9% for the comparative 2020 periods. The gross margin increase for both periods was primarily driven by cost reductions from our global procurement and productivity improvement initiatives and favorable volume, impacted by COVID-19 recovery, which were partially offset by cost inflation.

Selling, General and Administrative ("SG&A") Expenses

SG&A expenses increased by $16 million to $304 million, or 22.5% of revenue, in the second quarter of 2021, as compared to $288 million, or 24.8% of revenue, in the comparable 2020 period; and increased by $20 million to $605 million, or 23.2% of revenue, in the six months ended June 30, 2021, as compared to $585 million, or 25.6% of revenue, in the comparable 2020 period. The improvement in SG&A as a percent of revenue for both periods was primarily driven by cost reductions from our productivity, restructuring and other cost saving initiatives and decreased quality management costs, which were partially offset by cost inflation, additional investments in strategic growth initiatives and other costs.

Research and Development ("R&D") Expenses

R&D expense was $53 million, or 3.9% of revenue, in the second quarter of 2021, as compared to $44 million, or 3.8% of revenue, in the comparable 2020 period; and was $103 million, or 4.0% of revenue, in the six months ended June 30, 2021, as compared to $93 million, or 4.1% of revenue, in the comparable 2020 period.

Restructuring and Asset Impairment Charges

Restructuring

During the three and six months ended June 30, 2021, we recognized restructuring charges of $3 million and $8 million, respectively, of which $2 million and $6 million relate to actions previously announced in 2020. These charges included reduction of headcount across all segments and asset impairments within our Measurement & Control Solutions segment.

In response to the changes in business and economic conditions arising as a result of the COVID-19 pandemic, in June 2020 management committed to a restructuring plan that includes actions across our businesses and functions globally. The plan is designed to support our long-term financial resilience, simplify our operations, strengthen our competitive positioning and better serve our customers. During the three and six months ended June 30, 2020, we recognized restructuring charges of $38 million and $40 million, respectively. These charges included reduction of headcount across all segments and asset impairments within our Measurement & Control Solutions segment.

The following is a roll-forward for the six months ended June 30, 2021 and 2020 of employee position eliminations associated with restructuring activities:

	2021	2020
Planned reductions - January 1	319	196

The Water Infrastructure actions commenced in 2021 consist primarily of severance charges. These actions are expected to continue through the second quarter of 2022.

The Water Infrastructure, Applied Water, and Measurement & Control Solutions actions commenced in 2020 consist primarily of severance charges across segments and asset impairment charges in our Measurement & Control Solutions segment. These actions are expected to continue through the second quarter of 2022.

During the second quarter of 2020 the discontinuance of a product line resulted in $17 million of asset impairments, primarily related to customer relationships, trademarks and fixed assets within our Measurement & Control Solutions segment.

We currently expect to incur between $15 million and $25 million in restructuring costs for the full year. These

41

restructuring charges are primarily related to actions taken in response to the changes in business and economic conditions arising as a result of the COVID-19 pandemic as well as other efforts to optimize our cost structure, improve our operational efficiency and effectiveness, strengthen our competitive positioning and better serve our customers. We expect to realize between $33 million and $35 million of incremental net savings in 2021 from restructuring actions initiated in 2020. As a result of all of the actions taken and expected to be taken in 2021, we anticipate between $1 million and $3 million of total net savings to be realized during 2021.

Asset Impairment

During the second quarter of 2020 we determined that internally developed in-process software within our Measurement & Control Solutions segment was impaired as a result of actions taken to prioritize strategic investments. Accordingly, we recognized an impairment charge of $10 million. Refer to Note 7, "Goodwill and Other Intangible Assets," for additional information.

Operating Income

Operating income during the second quarter of 2021 was $160 million, reflecting an increase of 196.3% compared to $54 million in the second quarter of 2020. Operating margin was 11.8% for the second quarter of 2021 versus 4.7% for the comparable period in 2020, an increase of 710 basis points. Operating margin benefited from a decrease in restructuring and realignment costs of $37 million as compared to the second quarter of 2020 and special charges of $11 million incurred during 2020 that did not recur. Excluding the impact of these items, adjusted operating income was $166 million with an adjusted operating margin of 12.3% in the second quarter of 2021 as compared to adjusted operating income of $108 million with an adjusted operating margin of 9.3% in the second quarter of 2020. The increase in adjusted operating margin was primarily due to cost reductions from our productivity, restructuring and other cost saving initiatives and favorable volume, impacted by COVID-19 recovery. These impacts were partially offset by cost inflation and increased spending on strategic investments.

Operating income for the six months ended June 30, 2021 was $293 million, reflecting an increase of 154.8% compared to $115 million in 2020. Operating margin was 11.2% for the six months ended June 30, 2021 versus 5.0% for the comparable period in 2020, an increase of 620 basis points. Operating margin benefited from a decrease in restructuring and realignment costs of $38 million and a decrease in special charges of $9 million as compared to 2020. Excluding the impact of these items, adjusted operating income was $309 million with an adjusted operating margin of 11.9% for the six months ended June 30, 2021 as compared to adjusted operating income of $178 million with an adjusted operating margin of 7.8% in 2020. The increase in adjusted operating margin was primarily due to cost reductions from our productivity, restructuring and other cost saving initiatives and favorable volume, impacted by COVID-19 recovery. These impacts were partially offset by cost inflation and increased spending on strategic investments.

NM - Not meaningful percentage change

Water Infrastructure

Operating income for our Water Infrastructure segment increased $20 million, or 27.4%, for the second quarter of 2021 compared to the prior year, with operating margin also increasing from 14.6% to 16.3%. Operating margin benefited from a decrease in restructuring and realignment costs of $4 million during the quarter. Excluding these restructuring and realignment costs, adjusted operating income increased $16 million, or 19.8%, with adjusted operating margin increasing from 16.2% to 17.0%. The increase in adjusted operating margin for the quarter was primarily due to cost reductions from our productivity, restructuring and other cost saving initiatives, favorable volume and decreased inventory management costs. These impacts were partially offset by cost inflation, increased spending on strategic investments, increased employee-related costs and negative foreign currency impacts.

43

For the six months ended June 30, 2021, operating income for our Water Infrastructure segment increased $52 million, or 46.4%, as compared to the prior year, with operating margin also increasing from 11.9% to 15.2%. Operating margin benefited from a decrease in restructuring and realignment costs of $4 million in 2021. Excluding these restructuring and realignment costs, adjusted operating income increased $48 million, or 38.4%, with adjusted operating margin increasing from 13.3% to 16.0%. The increase in adjusted operating margin during the period was primarily due to cost reductions from our productivity, restructuring and other cost saving initiatives and favorable volume. These impacts were partially offset by cost inflation, increased spending on strategic investments, increased employee-related costs and other lesser impacts.

Applied Water

Operating income for our Applied Water segment increased $23 million, or 56.1%, for the second quarter of 2021 compared to the prior year, with operating margin also increasing from 12.2% to 15.5%. Operating margin benefited from a decrease in restructuring and realignment costs of $2 million during the quarter. Excluding these restructuring and realignment costs, adjusted operating income increased $21 million, or 46.7%, with adjusted operating margin increasing from 13.4% to 15.9%. The increase in adjusted operating margin for the quarter was primarily due to favorable volume, impacted by COVID-19 recovery, and cost reductions from our productivity, restructuring and other cost saving initiatives. These impacts were partially offset by cost inflation, increased logistics costs, increased employee-related costs and increased spending on strategic investments.

For the six months ended June 30, 2021, operating income for our Applied Water segment increased $42 million, or 47.7%, as compared to the prior year, with operating margin also increasing from 13.0% to 16.1%. Operating margin benefited from a decrease in restructuring and realignment costs of $3 million during the year which was partially offset by $1 million of special charges incurred in 2021. Excluding these items, adjusted operating income increased $40 million, or 42.6%, with adjusted operating margin increasing from 13.9% to 16.6%. The increase in adjusted operating margin during the period was primarily due to cost reductions from our productivity, restructuring and other cost saving initiatives and favorable volume, impacted by COVID-19 recovery. These impacts were partially offset by cost inflation, increased logistics costs, increased spending on strategic investments and increased employee-related costs.

Measurement & Control Solutions

Operating income for our Measurement & Control Solutions segment increased $59 million, or 128.3%, for the second quarter of 2021 compared to the prior year, with operating margin increasing from (14.3)% to 3.5%. Operating margin benefited from $31 million of restructuring and realignment costs and $10 million of special charges that were incurred during 2020 that did not recur during the quarter. Excluding these items, adjusted operating income increased $18 million, or 360.0%, with adjusted operating margin increasing from (1.6)% to 3.5%. The increase in adjusted operating margin for the quarter was primarily due to cost reductions from our restructuring, productivity and other cost saving initiatives, favorable volume, impacted by COVID-19 recovery, and favorable mix. These impacts were partially offset by cost inflation, increased spending on strategic investments and increased employee-related costs.

For the six months ended June 30, 2021, operating income for our Measurement & Control Solutions segment increased $80 million, or 137.9%, as compared to the prior year, with operating margin increasing from (8.7)% to 3.0%. Operating margin benefited from a decrease in restructuring and realignment costs of $31 million during the year and $10 million of special charges incurred in 2020 that did not recur. Excluding these items, adjusted operating income increased $39 million, or 260.0%, with adjusted operating margin increasing from (2.2)% to 3.3%. The increase in adjusted operating margin during the period was primarily due to cost reductions from our restructuring, productivity and other cost saving initiatives, decreased quality management costs, primarily due to a specific warranty charge recorded during the prior year that did not recur related to a firmware issue that was identified and addressed timely, favorable volume, driven by COVID-19 recovery and favorable mix. These impacts were partially offset by cost inflation, increased spending on strategic investments, increased employee-related costs and other lesser impacts.

Corporate and other

Operating loss for corporate and other decreased $4 million, or 28.6%, during the second quarter of 2021 compared to the prior year period. For the six months ended June 30, 2021, operating loss for corporate and other decreased $4 million, or 14.8%, compared to the same prior year period. The decreases in cost are driven by reduced costs related to COVID-19 initiatives.

44

Interest Expense

Interest expense was $21 million and $42 million for the three and six months ended June 30, 2021 and $18 million and $34 million for the three and six months ended June 30, 2020. The increase in interest expense for both periods is primarily driven by the issuance of our Green Bond during the second quarter of 2020. See Note 10, "Credit Facilities and Debt", of our condensed consolidated financial statements for a description of our credit facilities and long-term debt and related interest.

Income Tax Expense

The income tax provision for the three months ended June 30, 2021 was $25 million resulting in an effective tax rate of 18.5%, compared to a $4 million expense resulting in an effective tax rate of 10.9% for the same period in 2020. The income tax provision for the six months ended June 30, 2021 was $52 million resulting in an effective tax rate of 20.7%, compared to a $8 million expense resulting in an effective tax rate of 10.4% for the same period in 2020. The effective tax rate for the three and six month periods ended June 30, 2021 was lower than the U.S. federal statutory rate primarily due to favorable earnings mix, partially offset by the Global Intangible Low Taxed Income ("GILTI") inclusion. Additionally, the effective tax rate for the three and six month periods ended June 30, 2021 differ from the same periods in 2020 due to unfavorable earnings mix as compared to the prior year and favorable equity compensation deductions in the prior year. The effective tax rate for the six month period ended June 30, 2021 differs from the same period in 2020 due to the impact of tax settlements in the current period.

Liquidity and Capital Resources

The following table summarizes our sources and (uses) of cash:

	Six Months Ended
	June 30,
(In millions)	2021		2020		Change
Operating activities	$	206	$	179	$	27
Investing activities	(69)		(88)		19
Financing activities	(162)		774		(936)
Foreign exchange (a)	(10)		(12)		2
Total	$	(35)	$	853	$	(888)

(a)The impact is primarily due to the strengthening of the Canadian Dollar, the Chinese Yuan, the Russian Ruble and various other currencies against the U.S. Dollar.

Sources and Uses of Liquidity

Operating Activities

Net cash provided by operating activities was $206 million for the six months ended June 30, 2021 as compared to $179 million in the comparable prior year period. This increase was primarily driven by increased net cash earnings, partially offset by higher tax payments and increased working capital levels to support year-over-year growth.

Investing Activities

Cash used in investing activities was $69 million for the six months ended June 30, 2021 as compared to $88 million in the comparable prior year period. This decrease in cash used of $19 million was mainly driven by lower spending on capital expenditures compared to the prior year.

Financing Activities

Cash used by financing activities was $162 million for the six months ended June 30, 2021 as compared to cash generated of $774 million in the comparable prior year period. This net decrease in cash generated by financing activities during the period was primarily driven by the issuance of our Green Bond and higher levels of short-term debt during the prior year period, partially offset by the repayment of short-term debt during 2020 and an increase in share repurchase activity of $8 million.

Funding and Liquidity Strategy

Our ability to fund our capital needs depends on our ongoing ability to generate cash from operations and access to bank financing and the capital markets. As a result of uncertainties caused by the COVID-19 pandemic, we continue to evaluate aspects of our spending, including capital expenditures, strategic investments and dividends. We will continue to evaluate aspects of our spending as the year progresses and anticipate our capital expenditures will gradually begin to increase to normal levels during the year as the markets we operate in recover.

Historically, we have generated operating cash flow sufficient to fund our primary cash needs. We will continue to monitor the economic effects of the COVID-19 pandemic and its impact on the Company's future operating cash flows going forward. If our cash flows from operations are less than we expect, we may need to incur debt or issue equity. From time to time, we may need to access the long-term and short-term capital markets to obtain financing. Our access to, and the availability of, financing on acceptable terms and conditions in the future will be impacted by many factors, including: (i) our credit ratings or absence of a credit rating, (ii) the liquidity of the overall capital markets, and (iii) the current state of the economy. There can be no assurance that such financing will be available to us on acceptable terms or that such financing will be available at all. Our securities are rated investment grade. A significant change in credit rating could impact our ability to borrow at favorable rates. Refer to Note 10, "Credit Facilities and Debt", of our condensed consolidated financial statements for a description of limitations on obtaining additional funding.

We monitor our global funding requirements and seek to meet our liquidity needs on a cost-effective basis. As of June 30, 2021, the COVID-19 pandemic has not materially impacted our borrowing costs or other costs of capital, however the future impact of the COVID-19 pandemic is uncertain and may increase our borrowing costs and other costs of capital and otherwise adversely affect our business, results of operations, financial condition and liquidity.

We have considered the impacts of the COVID-19 pandemic on our liquidity and capital resources and do not currently expect it to impact our ability to meet future liquidity needs or continue to comply with debt covenants. Based on our current global cash positions, cash flows from operations and access to the capital markets, we believe there is sufficient liquidity to meet our funding requirements and service debt and other obligations in both the U.S. and outside of the U.S. during the year. In addition, we believe our existing committed credit facilities and access to the public debt markets would provide further liquidity if required. Currently, we have available liquidity of approximately $2.6 billion, consisting of $1.8 billion of cash and $800 million of available credit facilities as disclosed in Note 10, "Credit Facilities and Debt", of our condensed consolidated financial statements. Our debt repayment obligations in 2021 consist of $600 million in Senior Notes, which we expect to pay out of cash. Our next long-term debt maturity is March 2023.

Risk related to these items are described in our risk factor disclosures referenced under “Item 1A. Risk Factors" in our 2020 Annual Report.

Credit Facilities & Long-Term Contractual Commitments

See Note 10, "Credit Facilities and Debt", of our condensed consolidated financial statements for a description of our credit facilities and long-term debt.

Non-U.S. Operations

We generated approximately 56% of our revenue from non-U.S. operations for both the three and six months ended June 30, 2021 and approximately 51% and 50% for the three and six months ended June 30, 2020, respectively. As we continue to grow our operations in the emerging markets and elsewhere outside of the U.S., we expect to continue to generate significant revenue from non-U.S. operations and expect that a substantial portion of our cash will be predominately held by our foreign subsidiaries. We expect to manage our worldwide cash requirements considering available funds among the many subsidiaries through which we conduct business and the cost effectiveness with which those funds can be accessed. We may transfer cash from certain international subsidiaries to the U.S. and other international subsidiaries when we believe it is cost-effective to do so. We continually review our domestic and foreign cash profile, expected future cash generation and investment opportunities, and reassess whether there is a need to repatriate funds held internationally to support our U.S. operations. As of June 30, 2021, we have provided a deferred tax liability of $6 million for net foreign withholding taxes and state income taxes on $235 million of earnings expected to be repatriated to the U.S. parent as deemed necessary in the future.

Critical Accounting Estimates

Our discussion and analysis of our results of operations and capital resources are based on our condensed consolidated financial statements, which have been prepared in conformity with GAAP. The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities. We believe the most complex and sensitive judgments, because of their significance to the condensed consolidated financial statements, result primarily from the need to make estimates about the effects of matters that are inherently uncertain, particularly at this time and moving forward given the uncertainty around the magnitude and duration of the COVID-19 pandemic. Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2020 Annual Report describes the critical accounting estimates used in preparation of the condensed consolidated financial statements. Actual results in these areas could differ from management’s estimates. Other than as discussed below, there have been no significant changes in the information concerning our critical accounting estimates as stated in our 2020 Annual Report.

In the third quarter of 2020, management updated forecasts of future cash flows for the Advanced Infrastructure Analytics ("AIA") businesses, which reflected significant negative volume impacts from the COVID-19 pandemic, primarily on our assessment services business. Our ongoing investment in the AIA businesses also continues to impact near-term profitability. Based on these factors, we determined that there were indicators that the AIA reporting unit’s goodwill may be impaired, and accordingly, we performed an interim goodwill impairment test as of July 1, 2020. The results of the impairment test showed that the fair value of the AIA reporting unit was lower than the carrying value, resulting in a $58 million goodwill impairment charge. As of June 30, 2021, the remaining goodwill balance in our AIA reporting unit after recording the goodwill impairment charge was $112 million.

The uncertainty of the future impact of the COVID-19 pandemic may also contribute to further deterioration of our future cash flows. If we do not achieve our forecasts, it is possible that the goodwill of the AIA reporting unit could be deemed to be impaired again in a future period. The risks and potential impacts of COVID-19 on the fair value of our assets are included in our risk factor disclosures referenced under “Item 1A. Risk Factors" in the Company's 2020 Annual Report.

ITEM 3.             QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There has been no material change in the information concerning market risk as stated in our 2020 Annual Report.

ITEM 4.             CONTROLS AND PROCEDURES

Our management, with the participation of the Chief Executive Officer and Chief Financial Officer of the Company, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this quarterly report. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Based on such evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were effective at the reasonable assurance level.

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the 1934 Act) during the fiscal quarter covered by this quarterly report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

2011 OMNIBUS INCENTIVE PLAN

[YEAR] NON-QUALIFIED STOCK OPTION AWARD AGREEMENT

FOR CERTAIN EXECUTIVES & EXECUTIVE OFFICERS AS APPROVED BY THE LEADERSHIP DEVELOPMENT AND COMPENSATION COMMITTEE

This Agreement (the “Agreement”) between Xylem Inc. (the “Company”) and ###PARTICIPANT_NAME### (the “Participant”) is effective as of ###GRANT_DATE###. Terms used in this Agreement that are not defined in this Agreement are defined in the Company’s 2011 Omnibus Incentive Plan (the “Plan”). This Agreement is only being provided in English. The Participant is an employee of the Company or an Affiliate. In recognition of the Participant’s valued services, the Company, through the Leadership Development and Compensation Committee of its Board of Directors (the “Committee”), is providing the Participant an inducement to remain employed and an incentive for increased efforts while employed. In consideration of the terms and conditions in this Agreement, the parties agree as follows:

1.Grant of Non-Qualified Stock Options. The Company confirms the grant on ###GRANT_DATE###, (the “GrantDate”) to the Participant of the option to purchase from the Company all or any part of an aggregate of ###TOTAL_AWARDS### shares (the “Options”), at the purchase price of ###GRANT_PRICE### per share (the “ExercisePrice”).

Nature of the Grant:

(a)    The grant of Options is voluntary and occasional and does not create any contractual or other right to receive future grants of Options, or benefits in lieu of Options, even if Options have been granted in the past. All decisions with respect to future grants will be at the sole discretion of the Company;

(b)    The Participant is voluntarily participating in the Plan;

(c)    The Options are not part of normal or expected compensation for any purpose, including for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, pension or retirement or welfare benefits or similar payments;

(d)    Future value of the underlying shares is unknown, indeterminable and cannot be predicted with certainty;

(e)    No claim or entitlement to compensation or damages will arise from forfeiture of the Options resulting from the termination of the Participant's employment; and

(f)    The Company will not be liable for any foreign exchange rate fluctuation between the Participant’s local currency and the United States Dollar that may affect the value of the Options or of any amounts due to the Participant on exercise of the Options or on the subsequent sale of any shares acquired on exercise.

2.Terms and Conditions. The Options are subject to the following additional terms and conditions:

(a)    Expiration Date. The Options will expire on ###EXPIRY_DATE###, or, if the Participant’s employment terminates before that date, on the date specified in subsection 2(e) below.

1

(b)    Exercise of Options. The Options cannot be exercised until vested.

(c)    Vesting. Options will vest if the Participant has been actively employed by the Company or an Affiliate from the Grant Date through the vesting date. Active employment does not include any potential severance period.

Subject to subsections 2(a), 2(d), and 2(e), the Options will vest in 3 installments as follows:

###VEST_SCHEDULE_TABLE###

March 1, 2021, March 1, 2022, March 1, 2023 are the respective “Vest Period Start Dates” for each of the 3 installments.

(d)    Effect of Change in Control. In the event of a Change in Control prior to the vesting date, if the acquiring or surviving company in the transaction assumes or continues any then outstanding Options, then the unvested Options will continue to vest based on the Options’ service-based vesting criteria until the vesting date. If the Participant's active employment with the Company or an Affiliate is terminated by the Company or an Affiliate without Cause or by the Participant (for applicable Participants only) for Good Reason within 2 years of a Change in Control, any unvested and any converted Options will become 100% vested on the termination date. Any vested Options will expire on the earlier of ###EXPIRY_DATE###, or the date 3 months after the Participant's termination of active employment.

“Cause” means (i) the Participant’s willful and continued failure to substantially perform his, her or their duties with the Company or an Affiliate (other than any such failure resulting from the Participant’s incapacity due to physical or mental illness) or (ii) the Participant willfully engaging in conduct that demonstrably and materially injures the Company or its Affiliates, monetarily or otherwise. “Willful” means the action is done or omitted in bad faith or without reasonable belief that the action or omission was in the best interests of the Company.

“Good Reason” means (i) a reduction in annual target total cash compensation (base salary and target bonus), (ii) the assignment of any duties inconsistent in any material adverse respect with the Participant’s position, authority, duties or responsibilities, (iii) any other action by the Company or an Affiliate which results in a material diminution in such position, authority, duties or responsibilities; or (iv) the Company or an Affiliate requiring the Participant to relocate to a work location 50 miles or more from the location where the Participant was principally working immediately prior to the Change in Control. The Participant must give notice within 90 days of any Good Reason event.

Good Reason only applies to Company or Affiliate employees who are, at the time of termination of employment, covered by the Xylem Special Senior Executive Severance Pay Plan or the Xylem Enhanced Severance Pay Plan and will exclude an isolated, insubstantial and inadvertent action not taken in bad faith that is resolved by the Company or an Affiliate within 30 days of receiving notice.

(e)    Effect of Termination of Employment. Options will only vest while the Participant is actively employed by the Company or an Affiliate. If the Participant's active employment with the Company or an Affiliate is terminated for any reason prior to the vesting date, and such termination constitutes a “separation from service” within the meaning of Section 409A of the Code and any related regulations or other effective guidance promulgated thereunder (“Section 409A”), subject to subsection 2(d), the following would apply to any outstanding Options:

(i)    Termination due to Death or Disability. Any unvested Options will immediately become 100% vested on the Participant’s termination of employment. Any vested Options will expire on the

2

earlier of ###EXPIRY_DATE###, or the date 3 years after the Participant’s termination of employment.

(ii)    Termination due to Retirement or while Retirement Eligible. A prorated portion (as described below) of the unvested Options with a vesting date within 12 months of termination will immediately vest on the Participant’s termination of employment. All other unvested Options will automatically be forfeited. Any vested Options will expire on the earlier of ###EXPIRY_DATE###, or the date 3 years after the Participant’s termination of employment.

(iii)    Termination other than for Death, Disability and Retirement. Any unvested Options will automatically forfeit on the date of the Participant’s termination of employment. Any vested portion of the Options will expire on the earlier of ###EXPIRY_DATE###, or the date 3 years after the Participant’s termination of employment.

“Disability” means the complete and permanent inability of the Participant to perform all duties under the terms of his, her or their employment, as determined by the Company based on evidence, including independent medical reports and data, as deemed appropriate or necessary.

“Retirement” means the termination of the Participant's employment (either by the Company or an Affiliate, or the Participant), if, at the time of such termination, the Participant is at least age 55 and has completed 10 years of service with the Company or an Affiliate, or the Participant is age 65 or older.

Prorated Vesting Upon Retirement. The prorated portion of the Options that vests on the Participant’s termination of employment due to the Participant's Retirement will be determined by multiplying the total number of unvested Options with a vesting date within 12 months of termination by a fraction, of which the numerator is the number of full months (not to exceed 12) the Participant has been continually employed since the Vest Period Start Date, and the denominator is 12. For this purpose, full months of employment will be based on monthly anniversaries of the Grant Date, not calendar months.

(f)    Payment of Exercise Price. Permissible methods for payment of the Exercise Price on exercise of the Options are described in Section 6.6 of the Plan, or, if the Plan is amended, successor provisions. In addition to the methods of exercise permitted by Section 6.6 of the Plan, the Participant may exercise all or part of the Options by way of (i) broker-assisted cashless exercise in a manner consistent with the Federal Reserve Board's Regulation T, unless the Committee determines that this is prohibited by law, or (ii) net-settlement, where the Participant directs the Company to withhold shares that otherwise would be issued upon exercise of the Options having an aggregate Fair Market Value on the date of the exercise equal to the Exercise Price, or the portion being exercised by way of net-settlement (rounding up to the nearest whole share).

(g)    Tax Withholding. The Company will have the power and the right to deduct or withhold, or require the Participant to remit to the Company, all applicable federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to the exercise of the Options. The Participant may elect to satisfy the withholding requirement, in whole or in part, by having the Company withhold shares that otherwise would be issued upon exercise of the Options, with the number of shares withheld having a Fair Market Value on the date the tax is to be determined equal to the minimum statutory total tax that could be imposed on the transaction (or such other amount that will not cause an adverse accounting consequence or cost) (rounding up to the nearest whole share). Any election will be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate.

(h)    Automatic Exercise in Certain Circumstances. Subject to subsection 2(i) of this Agreement, if any Options held by an active Participant are otherwise exercisable but remain unexercised at the

3

close of business on ###EXPIRY_DATE###, and if on that date the Fair Market Value of the shares subject to the exercisable but unexercised Options exceeds the aggregate payment that would have been required to exercise the Options, the Participant will automatically be paid an amount of Company shares having a Fair Market Value equal to such excess (rounding up to the nearest whole share), if any, and the Options will be cancelled. An automatic exercise will not occur if the Participant (and, if applicable, the Participant’s authorized legal representative) waives this subsection 2(h) in writing.

The Participant acknowledges that tax and other legal requirements must be met prior to any settlement of Options under this subsection and consents to any tax or other consequences that may arise in connection with this subsection.

(i)    Compliance with Laws and Regulations. Notwithstanding anything to the contrary in this Agreement, the Company will not be obligated to issue any shares under this Agreement issuance of the shares, or the exercise of the Options by the Participant, violates or is not in compliance with any laws, rules or regulations of the United States or any state or country. The Participant understands that, if applicable, the laws of the country where the Participant is working at the time of grant, vesting, and/or exercise of the Options (including any rules or regulations governing securities, foreign exchange, tax, labor or other matters) may restrict or prevent exercise of the Options or may subject the Participant to additional procedural or regulatory requirements that the Participant is solely responsible for and that the Participant will have to independently fulfill. The Company reserves the right to impose other requirements on the Participant’s participation in the Plan, awards under the Plan, and any shares acquired under the Plan, if the Company determines the requirement is necessary or advisable to comply with applicable law or facilitate the administration of the Plan.

(j)    Participant Acknowledgements. The Participant acknowledges and agrees that:

(i)    Participant Obligations. In partial consideration for the award of these Options, if at any time during the period between the Grant Date and the 12-month period following the Participant’s termination of Employment (the “Obligation Period”), the Participant: (i) directly or indirectly, hires or solicits or arranges for the hiring or solicitation of any employee or customer of the Company or its Affiliates, or encourages any employee to leave the Company or an Affiliate; (ii) uses, discloses, misappropriates or transfers confidential or proprietary information concerning the Company or its Affiliates (except as required by the Participant’s work responsibilities with the Company or its Affiliates); or (iii) engages in any activity in violation of Company policies, including the Company’s Code of Conduct, or engages in conduct adverse to the best interests of the Company or its Affiliates; then the Options, whether previously vested or not, will be cancelled in full, and the Participant will be required to return to the Company any shares received on exercise of vested Options or the pre-tax income derived from any disposition of any shares received upon exercise of vested Options, unless the Company, in its sole discretion, elects not to cancel the Options.

The obligations in this subsection are in addition to any other agreements related to non-solicitation and preservation of Company confidential and proprietary information entered into between the Participant and the Company, or otherwise applicable to the Participant, and nothing in this Agreement is intended to waive, modify, alter or amend the terms of any such other agreement. THE PARTICIPANT UNDERSTANDS THAT THIS SUBSECTION IS NOT INTENDED TO AND DOES NOT PROHIBIT THE CONDUCT DESCRIBED, BUT PROVIDES FOR THE CANCELLATION OF THE AWARD IN FULL AND A RETURN TO THE COMPANY OF ANY SHARES RECEIVED UPON SETTLEMENT OF EXERCISED VESTED OPTIONS OR THE GROSS TAXABLE PROCEEDS FROM THE DISPOSITION OF ANY SHARES RECEIVED UPON SETTLEMENT OF EXERCISED VESTED OPTIONS IF THE PARTICIPANT SHOULD CHOOSE TO VIOLATE THIS PARAGRAPH DURING THE

4

OBLIGATION PERIOD. Nothing in this Agreement prohibits the Participant from voluntarily communicating, without notice to or approval by the Company, with any federal government agency about a potential violation of a federal law or regulation.

(ii)    Electronic Delivery and Acceptance. The Participant consents to electronic delivery of any Plan documents. The Participant consents to any and all procedures that the Company has established or may establish for an electronic signature system for delivery and acceptance of Plan related documents. The Participant agrees that his, her or their electronic signature is the same as, and will have the same force and effect as, his, her or their manual signature. Participant agrees that these procedures and delivery may be effected by a third party engaged by the Company to provide administrative services related to the Plan.

(iii)    Right of Set-Off. If the Company in its reasonable judgment determines that the Participant owes the Company or an Affiliate any amount due to any loan, obligation or indebtedness, including amounts owed under the Company’s tax equalization program or the Company’s policies with respect to travel and business expenses, and if the Participant has not satisfied such obligation(s), then the Company may instruct the plan administrator to withhold and/or sell shares acquired by the Participant on exercise of the Options (to the extent such shares are not subject to Code Section 409A), or the Company may deduct funds equal to the amount of the obligation from other funds due to the Participant from the Company to the maximum extent permitted by Code Section 409A.

(iv)    Data Privacy. Participant acknowledges and consents to the collection, use, processing and transfer of personal data. Participant is not obliged to consent to such collection, use, processing and transfer of personal data. However, failure to provide the consent may affect Participant’s ability to participate in the Plan. The Company holds certain personal information about Participant, that may include his/her name, home address and telephone number, date of birth, social security number or other employee identification number, salary grade, hire data, salary, nationality, job title, or details of all options or performance stock units or any other entitlement to shares of stock awarded, canceled, purchased, vested, or unvested, for the purpose of managing and administering the Plan (“Data”). The Company and its Affiliates will transfer Data amongst themselves as necessary for the purpose of implementation, administration and management of Participant’s participation in the Plan, and the Company or its Affiliates may each further transfer Data to any third parties assisting the Company with the implementation, administration and management of the Plan. These recipients may be located throughout the world, including the United States. The Participant authorizes them to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing participation in the Plan, including any transfer of Data that may be required for the administration of the Plan and/or the subsequent holding of shares of stock on Participant’s behalf to a broker or other third party with whom Participant may elect to deposit any shares of stock acquired pursuant to the Plan. Participant may, at any time, review Data, require any necessary amendments to it or withdraw this consent in writing by contacting Participant’s designated Human Resources professional; however, withdrawing consent may affect Participant’s ability to participate in the Plan. All Data will be managed in compliance with the Company’s Data Privacy Guidelines and applicable employee notifications, which may contain more stringent requirements, but in any case will not be less stringent than subsection 2(j)(iv).

(k)    Governing Law. This Agreement is issued, and the Options are granted, in Rye Brook, New York and will be governed and construed in accordance with the laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

5

By signing a copy of this Agreement, the Participant acknowledges that s/he has received a copy of the Plan and that s/he has read and understands the Plan and this Agreement and agrees to their terms and conditions. The Participant also acknowledges that the Options awarded under to this Agreement must be exercised prior to the expiration date, that it is the Participant's responsibility to exercise the Options, and that the Company has no further responsibility to notify the Participant of the expiration of the Options.

Restructuring Charges

Restructuring and Asset Impairment Charges

Restructuring

From time to time, the Company will incur costs related to restructuring actions in order to optimize our cost base and more strategically position ourselves. During the three and six months ended June 30, 2021, we recognized restructuring charges of $3 million and $8 million, respectively, of which $2 million and $6 million relate to actions previously announced in 2020. These charges included reduction of headcount across all segments and asset impairments within our Measurement & Control Solutions segment.

In response to the changes in business and economic conditions arising as a result of the COVID-19 pandemic, in June 2020 management committed to a restructuring plan that includes actions across our businesses and functions globally. The plan is designed to support our long-term financial resilience, simplify our operations, strengthen our competitive positioning and better serve our customers. During the three and six months ended June 30, 2020, we recognized restructuring charges of $38 million and $40 million, respectively. These charges included reduction of headcount across all segments and asset impairments within our Measurement & Control Solutions segment.

The following table presents the components of restructuring expense and asset impairment charges:

	Three Months Ended				Six Months Ended
	June 30,				June 30,

The Water Infrastructure actions commenced in 2021 consist primarily of severance charges. These actions are expected to continue through the second quarter of 2022.

The Water Infrastructure, Applied Water, and Measurement & Control Solutions actions commenced in 2020 consist primarily of severance charges across segments and asset impairment charges in our Measurement & Control Solutions segment. These actions are expected to continue through the second quarter of 2022.

During the second quarter of 2020 the discontinuance of a product line resulted in $17 million of asset impairments, primarily related to customer relationships, trademarks and fixed assets within our Measurement & Control Solutions segment.

Asset Impairment

During the second quarter of 2020 we determined that internally developed in-process software within our Measurement & Control Solutions segment was impaired as a result of actions taken to prioritize strategic investments. Accordingly, we recognized an impairment charge of $10 million. Refer to Note 7, "Goodwill and Other Intangible Assets," for additional information.

Background and Basis of Presentation

Background and Basis of Presentation

Background

Xylem Inc. (“Xylem” or the “Company”) is a leading equipment and service provider for water and wastewater applications with a broad portfolio of products and services addressing the full cycle of water, from collection, distribution and use to the return of water to the environment.

Xylem operates in three segments, Water Infrastructure, Applied Water and Measurement & Control Solutions. See Note 17, "Segment Information", to the condensed consolidated financial statements for further segment background information.

Except as otherwise indicated or unless the context otherwise requires, "Xylem," "we," "us," "our" and the "Company" refer to Xylem Inc. and its subsidiaries.

Basis of Presentation

The interim condensed consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions between our businesses have been eliminated.

The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair statement of the financial position and results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such SEC rules. We believe that the disclosures made are adequate to make the information presented not misleading. We consistently applied the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2020 ("2020 Annual Report") in preparing these unaudited condensed consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2020 Annual Report.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, post-retirement obligations and assets, revenue recognition, income taxes, valuation of intangible assets, goodwill and indefinite-lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates. The global outbreak of the novel coronavirus ("COVID-19") disease in March 2020, declared a pandemic by the World Health Organization, has created significant global volatility, uncertainty and economic disruption. The COVID-19 pandemic also has caused increased uncertainty in estimates and assumptions affecting the condensed consolidated financial statements. Actual results could differ from these estimates.

Our quarterly financial periods end on the Saturday closest to the last day of the calendar quarter, except for the fourth quarter which ends on December 31. For ease of presentation, the condensed consolidated financial statements included herein are described as ending on the last day of the calendar quarter.

Contract Balances

We receive payments from customers based on a billing schedule as established in our contracts. Contract assets relate to costs incurred to perform in advance of scheduled billings. Contract liabilities relate to payments received in advance of performance under the contracts. Changes in contract assets and liabilities are due to our performance under the contract.

The table below provides contract assets, contract liabilities, and significant changes in contract assets and liabilities:

Performance obligations

Delivery schedules vary from customer to customer based upon their requirements. Typically, large projects require longer lead production cycles and delays can occur from time to time. As of June 30, 2021, the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied for contracts with performance obligations, amount to $438 million. We expect to recognize the majority of revenue upon the completion of satisfying these performance obligations in the following 60 months. The Company elects to apply the practical expedient to exclude from this disclosure revenue related to performance obligations that are part of a contract whose original expected duration is less than one year.

Income Taxes

Income Taxes

Our quarterly provision for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items within periods presented. The comparison of our effective tax rate between periods is significantly impacted by the level and mix of earnings and losses by tax jurisdiction and discrete items.

The income tax provision for the three months ended June 30, 2021 was $25 million resulting in an effective tax rate of 18.5%, compared to a $4 million expense resulting in an effective tax rate of 10.9% for the same period in 2020. The income tax provision for the six months ended June 30, 2021 was $52 million resulting in an effective tax rate of 20.7%, compared to an $8 million expense resulting in an effective tax rate of 10.4% for the same period in 2020. The effective tax rate for the three and six month periods ended June 30, 2021 was lower than the U.S. federal statutory rate primarily due to favorable earnings mix, partially offset by the Global Intangible Low Taxed Income ("GILTI") inclusion. Additionally, the effective tax rate for the three and six month periods ended June 30, 2021 differ from the same periods in 2020 due to unfavorable earnings mix as compared to the prior year and favorable equity compensation deductions in the prior year. The effective tax rate for the six month period ended June 30, 2021 differs from the same period in 2020 due to the impact of tax settlements in the current period.

Unrecognized Tax BenefitsDuring 2019, Xylem’s Swedish subsidiary received a tax assessment for the 2013 tax year related to the tax treatment of an intercompany transfer of certain intellectual property that was made in connection with a reorganization of our European businesses. The assessment asserts an aggregate amount of approximately $80 million for tax, penalties and interest. Xylem filed an appeal with the Administrative Court of Stockholm. Management, in consultation with external legal advisors, believes it is more likely than not that Xylem will prevail on the proposed assessment and is vigorously defending our position through litigation. As of June 30, 2021, we have not recorded any unrecognized tax benefits related to this uncertain tax position.

(a)Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

(b)Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 13, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions, and we principally manage our exposures to these risks through management of our core business activities. Certain of our foreign operations expose us to fluctuations of foreign interest rates and exchange rates that may impact revenue, expenses, cash receipts, cash payments, and the value of our stockholders' equity. We enter into derivative financial instruments to protect the value or fix the amount of certain cash flows in terms of the functional currency of the business unit with that exposure and also reduce the volatility in stockholders' equity.

Cash Flow Hedges of Foreign Exchange Risk

We are exposed to fluctuations in various foreign currencies against our functional currencies. We use foreign currency derivatives, including currency forward agreements, to manage our exposure to fluctuations in the various exchange rates. Currency forward agreements involve fixing the foreign currency exchange rate for delivery of a specified amount of foreign currency on a specified date.

Certain business units with exposure to foreign currency exchange risks have designated certain currency forward agreements as cash flow hedges of forecasted intercompany inventory purchases and sales. Our principal currency exposures relate to the Euro, Swedish Krona, British Pound, Canadian Dollar, Polish Zloty and Australian Dollar. We had foreign exchange contracts with purchased notional amounts totaling $270 million and $0 million as of June 30, 2021 and December 31, 2020, respectively. As of June 30, 2021, our most significant foreign currency derivatives included contracts to sell U.S. Dollar and purchase Euro, purchase Swedish Krona and sell Euro, sell British Pound and purchase Euro, purchase Polish Zloty and sell Euro, purchase U.S. Dollar and sell Canadian Dollar, and to sell Canadian Dollar and purchase Euro. The purchased notional amounts associated with these currency derivatives are $97 million, $88 million, $36 million, $14 million, $13 million and $12 million, respectively.

Hedges of Net Investments in Foreign Operations

We are exposed to changes in foreign currencies impacting our net investments held in foreign subsidiaries.

Cross-Currency Swaps

Beginning in 2015, we entered into cross-currency swaps to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. During the second quarter of 2019 and third quarter of 2020 we entered into additional cross-currency swaps. The total notional amount of derivative instruments designated as net investment hedges was $1,208 million and $1,249 million as of June 30, 2021 and December 31, 2020, respectively.

Foreign Currency Denominated Debt

On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023. We designated the entirety of the outstanding balance, or $591 million and $610 million as of June 30, 2021 and December 31, 2020, respectively, net of unamortized discount, as a hedge of a net investment in certain foreign subsidiaries.

The table below presents the effect of our derivative financial instruments on the Condensed Consolidated Income Statements and Statements of Comprehensive Income:

Credit Facilities

2019 Five-Year Revolving Credit Facility

On March 5, 2019, Xylem entered into a Five-Year Revolving Credit Facility (the “2019 Credit Facility”) with Citibank, N.A., as Administrative Agent, and a syndicate of lenders. The 2019 Credit Facility provides for an aggregate principal amount of up to $800 million (available in U.S. Dollars and in Euros), with increases of up to $200 million for a maximum aggregate principal amount of $1 billion at the request of Xylem and with the consent of the institutions providing such increased commitments.

Interest on all loans under the 2019 Credit Facility is payable either quarterly or at the expiration of any LIBOR or EURIBOR interest period applicable thereto. Borrowings accrue interest at a rate equal to, at Xylem's election, a base rate or an adjusted LIBOR or EURIBOR rate plus an applicable margin. The 2019 Credit Facility includes customary provisions for implementation of replacement rates for LIBOR-based and EURIBOR-based loans. The 2019 Credit Facility also includes a pricing grid that determines the applicable margin based on Xylem's credit rating, with a further adjustment depending on Xylem's annual Sustainalytics Environmental, Social and Governance ("ESG") score, determined based on the methodology in effect as of March 5, 2019. Xylem will also pay quarterly fees to each lender for such lender’s commitment to lend accruing on such commitment at a rate based on our credit rating, whether such commitment is used or unused, as well as a quarterly letter of credit fee accruing on the letter of credit exposure of such lender during the preceding quarter at a rate based on the credit rating of Xylem (as adjusted for the ESG score). 

The 2019 Credit Facility requires that Xylem maintain a consolidated total debt to consolidated EBITDA ratio (or maximum leverage ratio), which will be based on the last four fiscal quarters; and in addition contains a number of customary covenants, including limitations on the incurrence of secured debt and debt of subsidiaries, liens, sale and lease-back transactions, mergers, consolidations, liquidations, dissolutions and sales of assets. The 2019 Credit Facility also contains customary events of default. Finally, Xylem has the ability to designate subsidiaries that can borrow under the 2019 Credit Facility, subject to certain requirements and conditions set forth in the 2019 Credit Facility. 

On June 22, 2020, Xylem entered into Amendment No. 1 to the 2019 Credit Facility (the "Amendment") which modified the financial covenant from a test based on the maximum leverage ratio (defined as consolidated total debt to consolidated EBITDA) to a test based on the net leverage ratio (defined as consolidated total debt less unrestricted cash and cash equivalents to consolidated EBITDA). This modification is effective through the quarter ending September 30, 2021, after which the covenant will revert back to the prior maximum leverage ratio test. The Amendment also restricted stock repurchases until March 31, 2021, except for shares of common stock in an amount not to exceed the number of shares issued after the date of the Amendment, subject to customary exceptions. As of June 30, 2021, the 2019 Credit Facility was undrawn and we are in compliance with all revolver covenants. 

Commercial Paper

U.S. Dollar Commercial Paper Program

Our U.S. Dollar commercial paper program generally serves as a means of short-term funding with a $600 million maximum issuing balance and a combined limit of $800 million inclusive of the 2019 Credit Facility. As of June 30, 2021 and December 31, 2020, none of the Company's $600 million U.S. Dollar commercial paper program was outstanding. We have the ability to continue borrowing under this program going forward in future periods.

Euro Commercial Paper Program

On June 3, 2019, Xylem entered into a Euro commercial paper program with ING Bank N.V., as administrative agent, and a syndicate of dealers. The Euro commercial paper program provides for a maximum issuing balance of up to €500 million (approximately $592 million) which may be denominated in a variety of currencies. The maximum issuing balance may be increased in accordance with the Dealer Agreement. As of June 30, 2021 and December 31, 2020, none of the Company's Euro commercial paper program was outstanding. We have the ability to continue borrowing under this program going forward in future periods.

The components of net periodic benefit cost, other than the service cost component, are included in the line item "Other non-operating expense, net" in the Condensed Consolidated Income Statements.

The total net periodic benefit cost for other post-retirement employee benefit plans was less than $1 million, including net credits recognized into other comprehensive income of less than $1 million, for both the three and six months ended June 30, 2021 and 2020, respectively.

We contributed $12 million and $16 million to our defined benefit plans during the six months ended June 30, 2021 and 2020, respectively. Additional contributions ranging between approximately $7 million and $15 million are expected to be made during the remainder of 2021.

During the first quarter of 2020, the Company purchased a bulk annuity policy with an insurance company for its largest defined benefit plan in the U.K., as a plan asset, to facilitate the termination and buy-out of the plan. The bulk annuity fully insures the benefits payable to the participants of the plan until a full buy-out of the plan can be executed, which is expected to occur in 2022. Included in the Company's six months ended June 30, 2020 contributions is $5 million paid to meet the shortfall between the cost of the bulk annuity policy and the plan assets.

The unrecognized compensation expense related to our stock options, restricted stock units and performance share units was $9 million, $30 million and $16 million, respectively, at June 30, 2021 and is expected to be recognized over a weighted average period of 2.1, 2.0 and 2.8 years, respectively. The amount of cash received from the exercise of stock options was $9 million and $5 million for the six months ended June 30, 2021 and 2020, respectively.

Stock Option Grants

The following is a summary of the changes in outstanding stock options for the six months ended June 30, 2021:

	Share units (in thousands)	Weighted Average Exercise Price / Share		Weighted  Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2021	1,961	$	56.66	6.4
Granted	259	102.31
Exercised	(135)	58.39
Forfeited and expired	(22)	83.88
Outstanding at June 30, 2021	2,063	$	61.93	6.3	$	122
Options exercisable at June 30, 2021	1,409	$	51.45	5.0	$	98
Vested and expected to vest as of June 30, 2021	1,987	$	60.98	6.2	$	119

The total intrinsic value of options exercised (which is the amount by which the stock price exceeded the exercise price of the options on the date of exercise) during the six months ended June 30, 2021 was $7.1 million.

Stock Option Fair Value

The fair value of each option grant was estimated on the date of grant using the binomial lattice pricing model which incorporates multiple and variable assumptions over time, including assumptions such as employee exercise patterns, stock price volatility and changes in dividends. The following are weighted-average assumptions for 2021 grants:

Volatility	26.30		%
Risk-free interest rate	0.86		%
Dividend yield	1.10		%
Expected term (in years)	5.7
Weighted-average fair value / share	$	23.20

Expected volatility is calculated based on an analysis of historic volatility measures for Xylem. We use historical data to estimate option exercise and employee termination behavior within the valuation model. Employee groups and option characteristics are considered separately for valuation purposes. The expected term represents an estimate of the period of time options are expected to remain outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of option grant.

Restricted Stock Unit Grants

The following is a summary of restricted stock unit activity for the six months ended June 30, 2021. The fair value of the restricted share unit awards is determined using the closing price of our common stock on date of grant:

	Share units (in thousands)	Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2021	537	$	74.62
Granted	213	103.36
Vested	(233)	74.47
Forfeited	(15)	85.91
Outstanding at June 30, 2021	502	$	86.47

ROIC Performance Share Unit Grants

The following is a summary of Return on Invested Capital ("ROIC") performance share unit grants for the six months ended June 30, 2021. The fair value of the ROIC performance share units is equal to the closing share price on the date of the grant:

	Share units  (in thousands)	Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2021	182	$	76.12
Granted	60	102.30
Forfeited (a)	(65)	76.04
Outstanding at June 30, 2021	177	$	84.66

(a) Includes ROIC performance share unit awards forfeited during the period as a result of the final performance condition not being achieved on vest date.

TSR Performance Share Unit Grants

The following is a summary of our Total Shareholder Return ("TSR") performance share unit grants for the six months ended June 30, 2021:

	Share units (in thousands)	Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2021	182	$	96.98
Granted	60	117.56
Adjustment for Market Condition Achieved (a)	35	98.79
Vested	(93)	98.79
Forfeited	(7)	102.66
Outstanding at June 30, 2021	177	$	102.86

(a) Represents an increase in the number of original TSR performance share units awarded based on the final market condition achievement at the end of the performance period of such awards.

The fair value of TSR performance share units was calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The following are weighted-average assumptions for 2021 grants:

Volatility	33.5	%
Risk-free interest rate	0.24	%

ESG Performance Share Unit Grants

During the first quarter of 2021, we issued a special grant of less than 0.1 million ESG performance share units. The shares will vest after five years based on our performance against certain of the Company's 2025 sustainability goals.

Commitments and Contingencies

Legal Proceedings

From time to time, we are involved in legal and regulatory proceedings that are incidental to the operation of our businesses (or the business operations of previously-owned entities). These proceedings may seek remedies relating to matters including environmental, tax, intellectual property, acquisitions or divestitures, product liability, property damage, personal injury, privacy, employment, labor and pension, government contract issues and commercial or contractual disputes.

From time to time, claims may be asserted against Xylem alleging injury caused by any of our products resulting from asbestos exposure. We believe there are numerous legal defenses available for such claims and would defend ourselves vigorously. Pursuant to the Distribution Agreement among ITT Corporation (now ITT LLC; acquired by Delticus HoldCo, L.P., a portfolio company of Warburg Pincus LLC, on July 1, 2021), Exelis (acquired by Harris Corporation, now L3Harris Technologies, Inc.) and Xylem, ITT LLC has an obligation to indemnify, defend and hold Xylem harmless for asbestos product liability matters, including settlements, judgments, and legal defense costs associated with all pending and future claims that may arise from past sales of ITT’s legacy products. We believe ITT LLC remains a substantial entity with sufficient financial resources to honor its obligations to us.

See Note 4, "Income Taxes", of our condensed consolidated financial statements for a description of a pending tax litigation matter.

Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on present information, including our assessment of the merits of the particular claims, we do not believe it is reasonably possible that any asserted or unasserted legal claims or proceedings, individually or in aggregate, will have a material adverse effect on our results of operations, or financial condition. We have estimated and accrued $5 million and $6 million as of June 30, 2021 and December 31, 2020, respectively, for these general legal matters.

Indemnifications

As part of our 2011 spin-off from our former parent, ITT Corporation (now ITT LLC; acquired by Delticus HoldCo, L.P., a portfolio company of Warburg Pincus LLC, on July 1, 2021), Exelis Inc. (acquired by Harris Corporation, now L3Harris Technologies, Inc.) and Xylem will indemnify, defend and hold harmless each of the other parties with respect to such parties’ assumed or retained liabilities under the Distribution Agreement and breaches of the Distribution Agreement or related spin agreements. ITT LLC's indemnification obligations include asserted and unasserted asbestos and silica liability claims that relate to the presence or alleged presence of asbestos or silica in products manufactured, repaired or sold prior to October 31, 2011, the Distribution Date, subject to limited exceptions with respect to certain employee claims, or in the structure or material of any building or facility, subject to exceptions with respect to employee claims relating to Xylem buildings or facilities. The indemnification associated with pending and future asbestos claims does not expire. Xylem has not recorded a liability for material matters for which we expect to be indemnified by the former parent or Exelis Inc. through the Distribution Agreement and we are not aware of any claims or other circumstances that would give rise to material payments from us under such indemnifications.

Guarantees

We obtain certain stand-by letters of credit, bank guarantees, surety bonds and insurance letters of credit from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance-related requirements. As of June 30, 2021 and December 31, 2020, the amount of surety bonds, bank guarantees, insurance letters of credit and stand-by letters of credit was $410 million and $378 million, respectively.

Environmental

In the ordinary course of business, we are subject to federal, state, local, and foreign environmental laws and regulations. We are responsible, or are alleged to be responsible, for ongoing environmental investigation and remediation of sites in various countries. These sites are in various stages of investigation and/or remediation and in many of these proceedings our liability is considered de minimis. We have received notification from the U.S. Environmental Protection Agency, and from similar state and foreign environmental agencies, that a number of sites formerly or currently owned and/or operated by Xylem or for which we are responsible under the Distribution Agreement, and other properties or water supplies that may be or have been impacted from those operations, contain disposed or recycled materials or wastes and require environmental investigation and/or remediation. These sites include instances where we have been identified as a potentially responsible party under federal and state environmental laws and regulations.

Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. Our accrued liabilities for these environmental matters represent our best estimates related to the investigation and remediation of environmental media such as water, soil, soil vapor, air and structures, as well as related legal fees. These estimates, and related accruals, are reviewed quarterly and updated for progress of investigation and remediation efforts and changes in facts and legal circumstances. Liabilities for these environmental expenditures are recorded on an undiscounted basis. We have estimated and accrued $3 million as of both June 30, 2021 and December 31, 2020 for environmental matters.

It is difficult to estimate the final costs of investigation and remediation due to various factors, including incomplete information regarding particular sites and other potentially responsible parties, uncertainty regarding the extent of investigation or remediation and our share, if any, of liability for such conditions, the selection of alternative remedial approaches, and changes in environmental standards and regulatory requirements. We believe the total amount accrued is reasonable based on existing facts and circumstances.

Warranties

We warrant numerous products, the terms of which vary widely. In general, we warrant products against defect and specific non-performance. The table below provides changes in the combined current and non-current product warranty accruals over each period:

(in millions)	2021		2020

Segment Reporting [Abstract]

Segment Information

Segment Information

Our business has three reportable segments: Water Infrastructure, Applied Water and Measurement & Control Solutions. The Water Infrastructure segment focuses on the transportation and treatment of water, offering a range of products including water, wastewater and storm water pumps, treatment equipment, and controls and systems. The Applied Water segment serves many of the primary uses of water and focuses on the residential, commercial and industrial markets. The Applied Water segment's major products include pumps, valves, heat exchangers, controls and dispensing equipment. The Measurement & Control Solutions segment focuses on developing advanced technology solutions that enable intelligent use and conservation of critical water and energy resources as well as analytical instrumentation used in the testing of water. The Measurement & Control Solutions segment's major products include smart metering, networked communications, measurement and control technologies, critical infrastructure technologies, software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions and testing equipment.

Additionally, we have Regional selling locations, which consist primarily of selling and marketing organizations and related support services, that offer products and services across our reportable segments. Corporate and other consists of corporate office expenses including compensation, benefits, occupancy, depreciation, and other administrative costs, as well as charges related to certain matters, such as environmental matters, that are managed at a corporate level and are not included in the business segments in evaluating performance or allocating resources.

The accounting policies of each segment are the same as those described in the summary of significant accounting policies (see Note 1 in the 2020 Annual Report). The following table contains financial information for each reportable segment:

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The interim condensed consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions between our businesses have been eliminated.

The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair statement of the financial position and results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such SEC rules. We believe that the disclosures made are adequate to make the information presented not misleading. We consistently applied the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2020 ("2020 Annual Report") in preparing these unaudited condensed consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2020 Annual Report.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, post-retirement obligations and assets, revenue recognition, income taxes, valuation of intangible assets, goodwill and indefinite-lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates. The global outbreak of the novel coronavirus ("COVID-19") disease in March 2020, declared a pandemic by the World Health Organization, has created significant global volatility, uncertainty and economic disruption. The COVID-19 pandemic also has caused increased uncertainty in estimates and assumptions affecting the condensed consolidated financial statements. Actual results could differ from these estimates.

Our quarterly financial periods end on the Saturday closest to the last day of the calendar quarter, except for the fourth quarter which ends on December 31. For ease of presentation, the condensed consolidated financial statements included herein are described as ending on the last day of the calendar quarter.

Diluted earnings per share	$	0.62	$	0.17	$	1.10	$	0.38

(a)Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

(b)Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 13, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.

[1] Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

[2] Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 13, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.
