Basis Of Presentation [Abstract]
Basis Of Presentation	Note 1 – Basis of Presentation The accompanying unaudited consolidated balance sheets and statements of capitalization of Essential Utilities, Inc. and subsidiaries (collectively, the “Company”, “we”, “us” or “our”) at March 31, 2023, and the unaudited consolidated statements of operations and comprehensive income, cash flows, and equity for the three months ended March 31, 2023 and 2022, have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim reporting and the rules and regulations for reporting on Quarterly Reports on Form 10-Q. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures and notes normally provided in annual financial statements and, therefore, should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Interim results are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, consisting of only recurring accruals, which are necessary to present a fair statement of its consolidated balance sheets, consolidated statements of equity, consolidated statements of operations and comprehensive income, and consolidated cash flow for the periods presented, have been made. The preparation of financial statements often requires the selection of specific accounting methods and policies. Significant estimates and judgments may be required in selecting and applying those methods and policies in the recognition of the assets and liabilities in its consolidated balance sheets, the revenues and expenses in its consolidated statements of operations and comprehensive income, and the information that is contained in its summary of significant accounting policies and notes to consolidated financial statements. Making these estimates and judgments requires the analysis of information concerning events that may not yet be complete and of facts and circumstances that may change over time. Furthermore, we are exposed to the uncertain state of the economy and macroeconomic conditions, including inflation and rising interest rates. As these continue to evolve, future events and effects related to these conditions cannot be determined with precision. Accordingly, actual amounts or future results can differ materially from those estimates that the Company includes currently in its consolidated financial statements, summary of significant accounting policies, and notes. There have been no changes to the summary of significant accounting policies previously identified in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

The purchase price allocation for these acquisitions consisted primarily of acquired property, plant and equipment.

The pro forma effect of the utility systems acquired is not material either individually or collectively to the Company’s results of operations.

Water and Wastewater Utility Acquisitions – Pending Completion

In April 2023, the Company entered into a purchase agreement to acquire Greenville Sanitation Authority’s wastewater utility assets, which serves approximately 2,300 customers in Greenville, Pennsylvania for $18,000.

In January 2023, the Company entered into a purchase agreement to acquire the water utility assets of La Rue, an Ohio municipality, which serves approximately 300 customers for $2,250.

In December 2022, the Company entered into a purchase agreement to acquire the wastewater utility assets of Union Rome Sewer, which serves approximately 5,300 customers in the southeast corner of Lawrence County, Ohio, for $25,500.

In August 2022, the Company entered into a purchase agreement to acquire a portion of the water and wastewater utility assets of the Village of Frankfort, an Illinois municipality, which serves approximately 1,400 customers for $1,400.

The purchase price for these pending acquisitions are subject to certain adjustments at closing, and are subject to regulatory approval, including the final determination of the fair value of the rate base acquired. We plan to finance the purchase price of these acquisitions by utilizing our revolving credit facility until permanent debt and common equity are secured. These pending acquisitions are expected to close in 2023 and in 2024. Closing for our utility acquisitions are subject to the timing of the respective regulatory approval processes.

DELCORA Purchase Agreement

In September 2019, the Company entered into a purchase agreement to acquire the wastewater utility system assets of the Delaware County Regional Water Quality Control Authority (“DELCORA”), which consists of approximately 16,000 customers, or the equivalent of 198,000 retail customers, in 42 municipalities in Southeast Pennsylvania for $276,500. In May 2020, Delaware County, Pennsylvania filed a lawsuit alleging that DELCORA does not have the legal authority to establish and fund a customer trust with the net proceeds of the transaction. In December 2020, the judge in the Delaware County Court lawsuit issued an order that (1) the County cannot interfere with the purchase agreement between DELCORA and the Company; (2) the County cannot terminate DELCORA prior to the closing

of the transaction; and (3) the establishment of the customer trust was valid. Delaware County appealed this decision to Commonwealth Court of Pennsylvania. On March 3, 2022, the Commonwealth Court issued a decision finding that Delaware County can dissolve the Authority if it so chooses, but the purchase agreement must be upheld regardless of who is operating the system. The case was remanded back to the trial court for the entry of an order consistent with the Commonwealth Court’s opinion. This order was issued on September 8, 2022 (“Remand Order”). Since then, the County has challenged the Remand Order through two separate actions:

First, Delaware County filed an Application for Determination of Finality (“Application”) on October 13, 2022. The Company filed its opposition to the Application on October 27, 2022, and on November 2, 2022, the Delaware County Court of Common Pleas denied Delaware County’s Application for Determination of Finality indicating that its previous order already constituted a final order that addressed the claims of all parties. On December 2, 2022, following the denial of its Application, Delaware County filed a Petition for Permission to Appeal (“Petition”) the Remand Order in the Commonwealth Court of Pennsylvania. On December 16, 2022, the Company filed an Answer in opposition to the Petition. The Commonwealth Court issued an Order denying the County’s Petition on February 2, 2023. The County filed an Application for Reconsideration of the Commonwealth Court’s February 2 Order, which the Commonwealth Court granted on April 4, 2023.

Second, on November 2, 2022, Delaware County filed a Notice of Appeal (“Notice of Appeal”) from the Remand Order. On December 2, 2022, the Delaware County of Common Pleas issued an Opinion concluding that the County Court did not err in issuing the Remand Order. On January 13, 2023, Delaware County filed an Application in Commonwealth Court seeking confirmation of briefing deadlines with respect to the Notice of Appeal. In response, by Order dated January 24, 2023, the Commonwealth Court stated that “the record received from the Court of Common Pleas of Delaware County is currently under review for finality. A briefing schedule will be issued upon completion of this review.” The Company filed an Application to quash the County’s Appeal on February 7, 2023. On April 4, 2023, the Commonwealth Court granted the Company’s Application and quashed the appeal.

On January 25, 2023, DELCORA filed in the Delaware Court of Common Pleas a complaint for Declaratory Judgment seeking resolution of whether the County Ordinance dissolving DELCORA is a final action prohibiting DELCORA from carrying out the material transaction of the Asset Purchase Agreement and, in the event that DELCORA retains the ability to close the transaction, whether DELCORA is permitted to exist as a trust.

Meanwhile, the administrative law judges (“ALJ”) in the regulatory approval process recommended that the Company’s application to acquire DELCORA be denied, and subsequently, the Company provided exceptions to the recommended decision. On March 30, 2021, the Pennsylvania Public Utility Commission (“PUC”) ruled that the case be remanded back to the Office of Administrative Law Judge and vacated the original administrative law judges’ recommended decision (“2021 Order”). This 2021 Order was also appealed to the Commonwealth Court by Delaware County on April 29, 2021. A decision was issued by the Commonwealth Court on September 12, 2022, which dismissed the appeal of the County.

After the PUC issued the 2021 Order, on April 16, 2021, the ALJ issued an order staying the proceeding until the Delaware County Court lawsuit is final and unappealable. On March 25, 2022, the Company sent a letter notifying the PUC of the March 3, 2022 Commonwealth Court decision (that originated in Delaware County Court of Common Pleas) and requested that the PUC move forward with processing the application. On July 14, 2022, the Commission moved to lift the stay imposed by the ALJ, and required the ALJ to establish a schedule on remand for the proceeding. The published procedural schedule has the proceeding concluding in June 2023.

On January 26, 2023, several parties involved in the PUC case filed a joint motion for stay based on DELCORA’s filing of the January 25, 2023 Complaint for Declaratory Judgment and referenced the City of Chester’s bankruptcy filing in which the City of Chester has asserted reversionary contract interests regarding to DELCORA’s wastewater assets. On February 6, 2023, the ALJ stayed the PUC DELCORA application proceedings again

The purchase price for this pending acquisition is subject to certain adjustments at closing, and is subject to regulatory approval, including the final determination of the fair value of the rate base acquired. We plan to finance the purchase price of this acquisition by the issuance of common stock and by utilizing our revolving credit facility until permanent debt is secured. Closing of our acquisition of DELCORA is subject to the timing of the regulatory approval process and on-going litigation.

Assets Held for Sale

Note 4 – Assets Held for Sale

In the fourth quarter of 2022, the Company decided to market for sale the assets of its regulated natural gas system in West Virginia that serves approximately 13,000 customers and is part of the Company’s Regulated Natural Gas segment. On December 31, 2022, the Company entered into a definitive agreement with Hope Gas, Inc. for the sale of its membership interests in its West Virginia assets for cash at closing of $37,000. The purchase price is subject to certain adjustments at closing and is subject to applicable regulatory approvals. Closing on the sale is expected in mid-2023, and completion of this transaction will conclude the Company’s operations in West Virginia. Based on an assessment of the sale price and the carrying value of the planned disposition, there is no anticipated impairment expected to be recognized because of this sale agreement. These assets and liabilities do not qualify as discontinued operations, are reported as held for sale in the Company’s consolidated balance sheet, and consist of the following:

The reclassification of goodwill to utility plant acquisition adjustment results from a mechanism approved by the applicable utility commission. The mechanism provides for the transfer over time, and the recovery through customer rates, of goodwill associated with some acquisitions upon achieving specific objectives.

Note 6 – Capitalization

At-the-Market Offering

On October 14, 2022, the Company entered into at-the market sales agreements (“ATM”) with third-party sales agents, under which the Company may offer and sell shares of its common stock, from time to time, at its option, having an aggregate gross offering price of up to $500,000 pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-255235). The Company intends to use the net proceeds from the sales of shares through the ATM for working capital, capital expenditures, water and wastewater utility acquisitions and repaying outstanding indebtedness. As of December 31, 2022, the Company issued 1,321,994 shares of common stock under the ATM for proceeds of $63,040, net of expenses. In January 2023, the Company issued 399,128 shares of common stock under the ATM for proceeds of $19,294, net of expenses.

Tangible Equity Units

On April 23, 2019, the Company issued $690,000, less expenses of $16,358, of its tangible equity units (the “Units”), with a stated amount of $50.00 per unit. This issuance was part of the permanent financing to close the Peoples Gas Acquisition. Each Unit consisted of a prepaid stock purchase contract and an amortizing note, each issued by the Company. The amortizing notes had an initial principal amount of $8.62909, or $119,081 in aggregate, and yielded interest at a rate of 3.00% per year, and paid equal quarterly per unit cash installments of $0.75 per amortizing note (except for the July 30, 2019 installment payment, which was $0.80833 per amortizing note), that constituted a payment of interest and a partial repayment of principal. This cash payment in the aggregate was equivalent to 6.00% per year with respect to each $50.00 stated amount of the Units. The amortizing notes represented unsecured senior obligations of the Company.

Certain holders of the tangible equity units had early settled their prepaid stock purchase contracts prior to the due date, and, in exchange, the Company issued shares of its common stock. During April 2022, 981,919 stock purchase contracts were early settled by the holders of the contracts, resulting in the issuance of 1,166,107 shares of the Company’s common stock. On May 2, 2022, the remaining 6,621,315 stock purchase contracts were each mandatorily settled for 1.18758 shares of the Company’s common stock, and in the aggregate the Company issued 7,863,354 shares of its common stock. Additionally, the final quarterly installment payment was made, which resulted in the complete pay-off of the amortizing notes.

Long-term Debt and Loans Payable

In January 2023 and October 2022, the Company’s subsidiary, Aqua Pennsylvania, issued $75,000 and $125,000 of first mortgage bonds, due in 2043 and 2052, and with interest rates of 5.60% and 4.50%, respectively. The proceeds from these bonds were used to repay existing indebtedness and for general corporate purposes.

On June 30, 2022, the following debt amendments were executed: (1) Peoples Natural Gas Companies amended its 364-day revolving credit agreement primarily to increase the amount of the facility from $100,000 to $300,000 and to update the termination date of the facility to June 29, 2023, and (2) Aqua Pennsylvania amended its 364-day revolving credit agreement primarily to update the termination date of the facility to June 29, 2023 to coincide with the term of the Peoples Natural Gas Companies’ facility.

On December 14, 2022, the Company entered into a five year $1,000,000 unsecured revolving credit facility, which replaced the Company’s prior five year $1,000,000 unsecured revolving credit facility. The Company’s new unsecured revolving credit facility was used to repay all indebtedness and fees under our prior unsecured revolving credit facility, and for other general corporate purposes. The facility includes a $100,000 sublimit for daily demand loan. Funds borrowed under this facility are classified as long-term debt and are used to provide working capital as well as support for letters of credit for insurance policies and other financing arrangements. As of March 31, 2023, the Company has the following sublimits and available capacity under the credit facility: $100,000 letter of credit sublimit, $82,362 of letters of credit available capacity, $0 borrowed under the swing-line commitment, $100,000 was available for borrowing under the swing-line commitment, $440,362 available for borrowing and $542,000 of funds borrowed under the agreement.

Financial Instruments

Note 7 – Financial Instruments

Financial instruments are recorded at carrying value in the financial statements and approximate fair value as of the dates presented. The fair value of these instruments is disclosed below in accordance with current accounting guidance related to financial instruments. There have been no changes in the valuation techniques used to measure fair value, or asset or liability transfers between the levels of the fair value hierarchy for the three months ended March 31, 2023 and 2022.

The fair value of loans payable is determined based on its carrying amount and utilizing Level 1 methods and assumptions. As of March 31, 2023 and December 31, 2022, the carrying amount of the Company’s loans payable was $22,500 and $228,500, respectively, which equates to their estimated fair value. The fair value of cash and cash equivalents, is determined based on Level 1 methods and assumptions. As of March 31, 2023 and December 31, 2022, the carrying amounts of the Company's cash and cash equivalents was $20,149 and $11,398, respectively, which equates to their fair value. The Company’s assets underlying the deferred compensation and non-qualified pension plans are determined by the fair value of mutual funds, which are based on quoted market prices from active markets utilizing Level 1 methods and assumptions. As of March 31, 2023 and December 31, 2022, the carrying amount of these securities was $24,934 and $24,962, respectively, which equates to their fair value, and is reported in the consolidated balance sheet in deferred charges and other assets.

Unrealized gain and losses on equity securities held in conjunction with our non-qualified pension plan is as follows:



	Three Months Ended
	March 31,
	2023		2022
Net gain (loss) recognized during the period on equity securities	$	131	$	(278)
Less: net gain / loss recognized during the period on equity securities sold during the period		-		-
Unrealized gain (loss) recognized during the reporting period on equity securities still held at the reporting date	$	131	$	(278)

The net gain (loss) recognized on equity securities is presented on the consolidated statements of operations and comprehensive income on the line item “Other.”

The carrying amounts and estimated fair values of the Company’s long-term debt is as follows:

The fair value of long-term debt has been determined by discounting the future cash flows using current market interest rates for similar financial instruments of the same duration utilizing Level 2 methods and assumptions.

The Company’s customers’ advances for construction have a carrying value of $118,269 as of March 31, 2023, and $114,732 as of December 31, 2022. Their relative fair values cannot be accurately estimated because future refund payments depend on several variables, including new customer connections, customer consumption levels, and future rates. Portions of these non-interest-bearing instruments are payable annually through 2032, and amounts not paid by the respective contract expiration dates become non-refundable. The fair value of these amounts would, however, be less than their carrying value due to the non-interest-bearing feature.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Net Income Per Common Share [Abstract]

Net Income Per Common Share

Note 8 – Net Income per Common Share

Basic net income per common share is based on the weighted average number of common shares outstanding and the weighted average minimum number of shares issued upon settlement of the stock purchase contracts issued under the tangible equity units. Diluted net income per common share is based on the weighted average number of common shares outstanding and potentially dilutive shares. The dilutive effect of employee stock-based compensation is included in the computation of diluted net income per common share. The dilutive effect of stock-based compensation is calculated using the treasury stock method and expected proceeds upon exercise of the stock-based compensation. The treasury stock method assumes that the proceeds from stock-based compensation is used to purchase the Company’s common stock at the average market price during the period. The following table summarizes the shares, in thousands, used in computing basic and diluted net income per common share:



	Three Months Ended
	March 31,
	2023	2022
Average common shares outstanding during the period for basic computation	264,192	261,952
Effect of dilutive securities:
Employee stock-based compensation	559	479
Average common shares outstanding during the period for diluted computation	264,751	262,431

For the three months ended March 31, 2022, the average common shares outstanding during the period for basic computation includes the weighted-average impact of 9,029,461 shares, based on the minimum number of shares to be issued upon settlement of the stock purchase contracts issued in April 2019 under the tangible equity units. On May 2, 2022, all of the remaining stock purchase contracts under the tangible equity units were mandatorily settled.

The number of outstanding employee stock options that were not included in the diluted earnings per share calculation because the effect would have been anti-dilutive was 152,138 for the three months ended March 31, 2023. For the three months ended March 31, 2022, all of the Company’s outstanding employee stock options were included in the calculations of diluted net income per share as the calculated cost to exercise employee stock options was less than the average market price of the Company’s common stock during this period. Additionally, the dilutive effect of performance share units and restricted share units granted are included in the Company’s calculation of diluted net income per share.

Stock-Based Compensation [Abstract]

Stock-Based Compensation

Note 9 – Stock-based Compensation

Under the Company’s Amended and Restated Equity Compensation Plan (the “Plan”) approved by the Company’s shareholders on May 2, 2019, to replace the 2004 Equity Compensation Plan, stock options, stock units, stock awards, stock appreciation rights, dividend equivalents, and other stock-based awards may be granted to employees, non-employee directors, and consultants and advisors. The Plan authorizes 6,250,000 shares for issuance under the Plan. A maximum of 3,125,000 shares under the

Plan may be issued pursuant to stock awards, stock units and other stock-based awards, subject to adjustment as provided in the Plan. During any calendar year, no individual may be granted (i) stock options and stock appreciation rights under the Plan for more than 500,000 shares of Company stock in the aggregate or (ii) stock awards, stock units or other stock-based awards under the Plan for more than 500,000 shares of Company stock in the aggregate, subject to adjustment as provided in the Plan. Awards to employees and consultants under the Plan are made by a committee of the Board of Directors of the Company, except that with respect to awards to the Chief Executive Officer, the committee recommends those awards for approval by the non-employee directors of the Board of Directors. In the case of awards to non-employee directors, the Board of Directors makes such awards. At March 31, 2023, 1,506,059 shares were still available for issuance under the Plan. No further grants may be made under the Company’s 2004 Equity Compensation Plan.

Performance Share Units – A performance share unit (“PSU”) represents the right to receive a share of the Company’s common stock if specified performance goals are met over the three year performance period specified in the grant, subject to exceptions through the respective vesting period, which is generally three years. Each grantee is granted a target award of PSUs and may earn between 0% and 200% of the target amount depending on the Company’s performance against the performance goals. The following table provides compensation expense for PSUs:



	Three Months Ended
	March 31,
	2023		2022
Stock-based compensation within operations and maintenance expenses	$	2,443	$	1,650
Income tax benefit		612		467

The following table summarizes the PSU transactions for the three months ended March 31, 2023:



	Number	Weighted
	of	Average
	Share Units	Fair Value
Nonvested share units at beginning of period	556,462	$	42.77
Granted	161,981		45.06
Actual vested	(157,862)		53.83
Forfeited	(1,310)		42.79
Nonvested share units at end of period	559,271		43.81

A portion of the fair value of PSUs was estimated at the grant date based on the probability of satisfying the market-based conditions using the Monte Carlo valuation method, which assesses probabilities of various outcomes of market conditions. The other portion of the fair value of the PSUs is based on the fair market value of the Company’s stock at the grant date, regardless of whether the market-based condition is satisfied. The per unit weighted-average fair value at the date of grant for PSUs granted during the three months ended March 31, 2023 and 2022 was $45.06 and $42.31, respectively. The fair value of each PSU grant is amortized monthly into compensation expense on a straight-line basis over their respective vesting periods, generally 36 months. The accrual of compensation costs is based on the Company’s estimate of the final expected value of the award and is adjusted as required for the portion based on the performance-based condition. The Company assumes that forfeitures will be minimal, and recognizes forfeitures as they occur, which results in a reduction in compensation expense. As the payout of the PSUs includes dividend equivalents, no separate dividend yield assumption is required in calculating the fair value of the PSUs. The recording of compensation expense for PSUs has no impact on net cash flows.

Restricted Stock Units – A restricted stock unit (“RSU”) represents the right to receive a share of the Company’s common stock. RSUs are eligible to be earned at the end of a specified restricted period, which is generally three years, beginning on the date of grant. The Company assumes that forfeitures will be minimal and recognizes forfeitures as they occur, which results in a reduction in compensation expense. As the payout of the RSUs includes dividend equivalents, no separate dividend yield assumption is required in calculating the fair value of the RSUs. The following table provides the compensation expense and income tax benefit for RSUs:



	Three Months Ended
	March 31,
	2023		2022
Stock-based compensation within operations and maintenance expenses	$	681	$	777
Income tax benefit		171		219

The following table summarizes the RSU transactions for the three months ended March 31, 2023:



	Number	Weighted
	of	Average
	Stock Units	Fair Value
Nonvested stock units at beginning of period	180,306	$	45.94
Granted	73,696		45.61
Stock units vested and issued	(50,555)		49.44
Forfeited	(495)		43.29
Nonvested stock units at end of period	202,952		44.95

The per unit weighted-average fair value at the date of grant for RSUs granted during the three months ended March 31, 2023 and 2022 was $45.61 and $45.10, respectively.

Stock Options – A stock option represents the option to purchase a number of shares of common stock of the Company as specified in the stock option grant agreement at the exercise price per share as determined by the closing market price of our common stock on the grant date. Stock options are exercisable in installments of 33% annually, starting one year from the grant date and expire 10 years from the grant date, subject to satisfaction of designated performance goals. The fair value of each stock option is amortized into compensation expense using the graded-vesting method, which results in the recognition of compensation costs over the requisite service period for each separately vesting tranche of the stock options as though the stock options were, in substance, multiple stock option grants. The following table provides the compensation cost and income tax benefit for stock-based compensation related to stock options:



	Three Months Ended
	March 31,
	2023		2022
Stock-based compensation within operations and maintenance expenses	$	77	$	100
Income tax benefit		19		28

The fair value of options was estimated at the grant date using the Black-Scholes option-pricing model. The following assumptions were used in the application of this valuation model:


	2023
Expected term (years)		5.5
Risk-free interest rate		4.03%
Expected volatility		27.80%
Dividend yield		2.53%
Grant date fair value per option	$	11.37

Historical information was the principal basis for the selection of the expected term and dividend yield. The expected volatility is based on a weighted-average combination of historical and implied volatilities over a time period that approximates the expected term of the option. The risk-free interest rate was selected based upon the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option.

The following table summarizes stock option transactions for the three months ended March 31, 2023:



		Weighted		Weighted
		Average		Average	Aggregate
		Exercise		Remaining	Intrinsic
	Shares	Price		Life (years)	Value
Outstanding at beginning of period	820,061	$	36.29
Granted	74,632		45.39
Exercised	(2,917)		35.21
Outstanding at end of period	891,776	$	37.05	6.3	$	6,130,820

Exercisable at end of period	766,704	$	35.71	5.8	$	6,130,820

Restricted Stock – Restricted stock awards provide the grantee with the rights of a shareholder, including the right to receive dividends and to vote such shares, but not the right to sell or otherwise transfer the shares during the restriction period. Restricted stock awards result in compensation expense that is equal to the fair market value of the stock on the date of the grant and is amortized ratably over the restriction period. The Company expects forfeitures of restricted stock to be de minimis. The following table provides the compensation cost and income tax benefit for stock-based compensation related to restricted stock:

The following table summarizes restricted stock transactions for the three months ended March 31, 2023:


	Number	Weighted

Vested	-		-
Nonvested restricted stock at end of period	1,170	$	42.75

There were no restricted stock awards granted during the three months ended March 31, 2023.

Stock Awards – Stock awards represent the issuance of the Company’s common stock, without restriction. The issuance of stock awards results in compensation expense that is equal to the fair market value of the stock on the grant date and is expensed immediately upon grant. The following table provides the compensation cost and income tax benefit for stock-based compensation related to stock awards:



	Three Months Ended

Rate Activity [Abstract]

Rate Activity

Note 11 – Rate Activity

On March 28, 2023, the Company received authorization, in advance of the final order being approved, to implement infrastructure rehabilitation surcharges designed to increase total operating revenues on an annual basis by $7,685 in its water and wastewater utility operating divisions in Texas effective on April 1, 2023. The additional revenue billed and collected prior to the final order is subject to refund based on the outcome of the ruling.

During the first three months of 2023, the Company’s two other water utility operating divisions in Ohio implemented base rate increases designed to increase total operating revenues on an annual basis by $1,569. Further, one of the Company’s wastewater divisions in Indiana implemented a base rate increase designed to increase operating revenues on an annual basis by $134. Lastly, during the first three months of 2023, the Company implemented infrastructure rehabilitation surcharges designed to increase total operating revenues on an annual basis by $1,846 in its water and wastewater utility operating divisions in Illinois and by $1,483 in its natural gas operating division in Kentucky.

On December 30, 2022, our water and wastewater utility operating divisions in Ohio filed an application with the Public Utilities Commission of Ohio designed to increase rates by $9,816 annually.

On September 21, 2022, our regulated water and wastewater utility operating divisions in Ohio received an order from the Public Utilities Commission of Ohio which will increase operating revenues by $5,483 annually. New rates for water and sewer service went into effect on September 21, 2022.

On June 30, 2022, the Company’s regulated water and wastewater operating subsidiary in North Carolina, Aqua North Carolina, filed an application with the North Carolina Utilities Commission designed to increase rates by $18,064 in the first year of new rates being implemented, then an

additional $4,303 and $4,577 in the second and third years, respectively. In February 2023, the Company implemented interim rates which may be subject to refund for the difference between interim and final approved rates pending the final order.

On May 16, 2022, the Company’s regulated water and wastewater operating subsidiary in Pennsylvania, Aqua Pennsylvania, received an order from the Pennsylvania Public Utility Commission that allowed base rate increases that would increase total annual operating revenues by $69,251. New rates went into effect on May 19, 2022. At the time the rate order was received, the rates in effect also included $35,470 in Distribution System Improvement Charges (“DSIC”), which was 7.2% above prior base rates. Consequently, the aggregate base rates increased by $104,721 since the last base rate increase and DSIC was reset to zero.

On January 3, 2022, the Company’s natural gas operating division in Kentucky received an order from the Kentucky Public Service Commission resulting in an increase of $5,238 in annual revenues, and new rates went into effect on January 4, 2022. On June 7, 2022, an additional $260 was approved and made effective by the Commission, resulting from a rehearing requested by the operating division.

Segment Information [Abstract]

Segment Information

Note 13 – Segment Information

The Company has eleven operating segments and two reportable segments. The Regulated Water segment is comprised of eight operating segments representing its water and wastewater regulated utility companies, which are organized by the states where the Company provides water and wastewater services. The eight water and wastewater utility operating segments are aggregated into one reportable segment, because each of these operating segments has the following similarities: economic characteristics, nature of services, production processes, customers, water distribution or wastewater collection methods, and the nature of the regulatory environment. The Regulated Natural Gas segment is comprised of one operating segment representing natural gas utility companies, acquired in the Peoples Gas Acquisition, for which the Company provides natural gas distribution services.

In addition to the Company’s two reportable segments, we include two of our operating segments within the Other category below. These segments are not quantitatively significant and are comprised of our non-regulated natural gas operations and Aqua Resources. Our non-regulated natural gas operations consist of utility service line protection solutions and repair services to households and the operation of gas marketing and production entities. Aqua Resources offers, through a third party, water and sewer service line protection solutions and repair services to households. In addition to these segments, Other is comprised of business activities not included in the reportable segments, corporate costs that have not been allocated to the Regulated Water and Regulated Natural Gas segments, and intersegment eliminations. Corporate costs include general and administrative expenses, and interest expense. The Company reports these corporate costs within Other as they relate to corporate-focused responsibilities and decisions and are not included in internal measures of segment operating performance used by the Company to measure the underlying performance of the operating segments.

The following table presents information about the Company’s reportable segments:

Commitments And Contingencies	3 Months Ended
Commitments And Contingencies	Mar. 31, 2023
Commitments And Contingencies [Abstract]
Commitments And Contingencies	Note 14 – Commitments and Contingencies The Company is routinely involved in various disputes, claims, lawsuits and other regulatory and legal matters, including both asserted and unasserted legal claims, in the ordinary course of business. The status of each such matter, referred to herein as a loss contingency, is reviewed and assessed in accordance with applicable accounting rules regarding the nature of the matter, the likelihood that a loss will be incurred, and the amounts involved. As of March 31, 2023, the aggregate amount of $19,500 is accrued for loss contingencies and is reported in the Company’s consolidated balance sheet as other accrued liabilities and other liabilities. These accruals represent management’s best estimate of probable loss (as defined in the accounting guidance) for loss contingencies or the low end of a range of losses if no single probable loss can be estimated. For some loss contingencies, the Company is unable to estimate the amount of the probable loss or range of probable losses. Further, Essential Utilities has insurance coverage for certain of these loss contingencies, and as of March 31, 2023, estimates that approximately $1,476 of the amount accrued for these matters are probable of recovery through insurance, which amount is also reported in the Company’s consolidated balance sheet as deferred charges and other assets, net. During a portion of 2019, the Company initiated a do not consume advisory for some of its customers in one division served by the Company’s Illinois subsidiary. The do not consume advisory was lifted in 2019 and, in 2022, the water system was determined to be in compliance with the federal Lead and Copper Rule. During the second quarter of 2021, an amount was accrued for the portion of the fine or penalty that we determined to be probable and estimable of being incurred. In addition, on September 3, 2019, two individuals, on behalf of themselves and those similarly situated, commenced an action against the Company’s Illinois subsidiary in the State court in Will County, Illinois related to this do not consume advisory. The complaint seeks class action certification, attorney's fees, and "damages, including, but not limited to, out of pocket damages, and discomfort, aggravation, and annoyance” based upon the water provided by the Company’s subsidiary to a discrete service area in University Park, Illinois. The complaint contains allegations of damages as a result of supplied water that exceeded the standards established by the federal Lead and Copper Rule. The complaint is in the discovery phase and class certification has not been granted. During the third quarter of 2022, the Company established an accrual for the amount of loss asserted in the complaint that we determined to be probable and estimable of being incurred. The Company is vigorously defending against this claim. The Company submitted a claim for the expenses incurred to its insurance carrier for potential recovery of a portion of these costs and is currently in litigation with one of its carriers seeking to enforce its claims. The Company continues to assess the potential loss contingency on this matter. While the final outcome of this claim cannot be predicted with certainty, and unfavorable outcomes could negatively impact the Company, at this time in the opinion of management, the final resolution of this matter is not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows. Although the results of legal proceedings cannot be predicted with certainty, other than disclosed above, there are no pending legal proceedings to which the Company or any of its subsidiaries is a party or to which any of its properties is the subject that are material or are expected to have a material effect on the Company’s financial position, results of operations, or cash flows. In addition to the aforementioned loss contingencies, the Company self-insures a portion of its employee medical benefit program, and maintains stop-loss coverage to limit the exposure arising from these claims. The Company’s reserve for these claims totaled $2,327 at March 31, 2023 and represents a reserve for unpaid claim costs, including an estimate for the cost of incurred but not reported claims.

Income Taxes [Abstract]

Income Taxes

Note 15 – Income Taxes

The Company’s effective tax rate was (19.8)% and (9.5)% for the three months ended March 31, 2023 and 2022, respectively. The decrease in the effective tax rate for the first quarter of the year is primarily attributed to the increase in income tax benefits associated with the tax deduction for qualifying infrastructure. In determining its interim tax provision, the Company reflects its estimated permanent and flow-through tax differences for the taxable year.

The statutory Federal tax rate is 21.0% for the three months ended March 31, 2023 and 2022. For states with a corporate net income tax, the state corporate net income tax rates range from 2.5% to 8.99% for all periods presented. On July 8, 2022, Pennsylvania enacted House Bill 1342 into law, which among other things, reduces Pennsylvania’s corporate income tax rate from 9.99% to 8.99% beginning January 1, 2023, and an additional 0.5% annually through 2031, when it reaches to 4.99%. The Company evaluated the impacts of the tax rate change and recorded, in the year ended December 31, 2022, a reduction to our deferred tax liabilities of $244,537 with a corresponding reduction primarily to our regulatory assets.

The Company uses a method of tax accounting for certain qualifying infrastructure investments at its Peoples Natural Gas and Peoples Gas Company subsidiaries, its largest natural gas subsidiaries in Pennsylvania, that allows a tax deduction for qualifying utility infrastructure. In the fourth quarter of 2022, the Company applied the same method of tax accounting for its Aqua New Jersey subsidiary. Consistent with the Company’s accounting for differences between book and tax expenditures in Pennsylvania in its other regulated subsidiaries, the Company uses the flow-through method to account for this timing difference. In April 2023, the Internal Revenue Service issued Revenue Procedure 2023-15 which provides a safe harbor method of accounting that taxpayers may use to determine whether expenses to repair, maintain, replace, or improve natural gas transmission and distribution property must be capitalized for tax purposes. The Company is evaluating this guidance to determine the impact, if any, on the Company’s tax position.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Recent Accounting Pronouncements

Note 16 – Recent Accounting Pronouncements

Pronouncement adopted during the year:

In October 2021, the FASB issued accounting guidance on accounting for acquired revenue contracts with customers in a business combination. The guidance specifies for all acquired revenue contracts, regardless of their timing of payment, the circumstances in which the acquirer should recognize contract assets and contract liabilities that are acquired in a business combination, as well as how to measure those contract assets and contract liabilities. The updated accounting guidance is effective for fiscal years beginning after December 15, 2022 with early adoption permitted. The Company adopted this guidance effective January 1, 2023, and will apply it prospectively to business combinations occurring on or after that date.

Basis Of Presentation [Abstract]

Basis of Presentation

The accompanying unaudited consolidated balance sheets and statements of capitalization of Essential Utilities, Inc. and subsidiaries (collectively, the “Company”, “we”, “us” or “our”) at March 31, 2023, and the unaudited consolidated statements of operations and comprehensive income, cash flows, and equity for the three months ended March 31, 2023 and 2022, have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim reporting and the rules and regulations for reporting on Quarterly Reports on Form 10-Q. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures and notes normally provided in annual financial statements and, therefore, should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Interim results are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, consisting of only recurring accruals, which are necessary to present a fair statement of its consolidated balance sheets, consolidated statements of equity, consolidated statements of operations and comprehensive income, and consolidated cash flow for the periods presented, have been made.

The preparation of financial statements often requires the selection of specific accounting methods and policies. Significant estimates and judgments may be required in selecting and applying those methods and policies in the recognition of the assets and liabilities in its consolidated balance sheets, the revenues and expenses in its consolidated statements of operations and comprehensive income, and the information that is contained in its summary of significant accounting policies and notes to consolidated financial statements. Making these estimates and judgments requires the analysis of information concerning events that may not yet be complete and of facts and circumstances that may change over time. Furthermore, we are exposed to the uncertain state of the economy and macroeconomic conditions, including inflation and rising interest rates. As these continue to evolve, future events and effects related to these conditions cannot be determined with precision. Accordingly, actual amounts or future results can differ materially from those estimates that the Company includes currently in its consolidated financial statements, summary of significant accounting policies, and notes.
