Exhibit 99.1

ESSENTIAL UTILITIES, INC. REPORTS EARNINGS FOR 2019

BRYN MAWR, PA – Essential Utilities, Inc. (NYSE:WTRG) (Essential), formerly Aqua America, Inc., today reported results for the fourth quarter and year ended Dec. 31, 2019. The new name and ticker became effective Monday, Feb. 3, 2020 to reflect the combination, following the pending acquisition of Peoples, a natural gas distribution company, of regulated water utilities and natural gas utilities that offer essential utility services to customers. Upon completion of the acquisition, the water and wastewater utility services will be provided through Essential Utilities’ Aqua companies and the natural gas utility services will be provided primarily through its Peoples natural gas companies.

Full-year 2019 operating results

Essential reported total operating revenues of $889.7 million in 2019, an increase of 6.2 percent compared to $838.1 million in the prior year. Rates and customer growth from both acquisitions and organic growth were the largest contributors to the increase in revenues.

Operations and maintenance expenses were $333.1 million for 2019 compared to $308.5 million in the prior year. Peoples transaction-related expenses, employee-related costs, and growth-related costs were the primary drivers of the increase in operations and maintenance expenses. The expense growth rate would have been more in line with Essential’s historic expectations without the impact from current and prior year items, such as a favorable regulatory liability adjustment recognized in 2018 and the Peoples transaction-related expenses and acquisition costs in 2019 and 2018.

For the full year 2019, Essential reported net income of $224.5 million (GAAP) or $1.04 per share (GAAP), compared to $192.0 million (GAAP) or $1.08 per share (GAAP) in 2018, an increase in net income of 17.0 percent from the prior year. Excluding the Peoples transaction-related items and the

additional shares issued through the April 2019 equity offerings, adjusted income for 2019 was $263.5 million (non-GAAP) or $1.47 per share (non-GAAP), compared to $1.41 per share (non-GAAP) in 2018, an increase in adjusted income per share of 4.3 percent from the prior year. Higher earnings from rates and surcharge revenues and customer growth contributed to the strong performance in net income. The mark-to-market adjustment on interest rate swaps also contributed favorably to GAAP earnings growth. Please refer to the reconciliation of GAAP to non-GAAP financial measures later in this press release for additional information on Essential’s use of non-GAAP financial measures as a supplement to its GAAP results.

“2019 marked a historic year for the company with record capital spending of $550 million on infrastructure improvements, our announcement of an agreement with Delaware County Regional Water Quality Control Authority (DELCORA), which represents the largest municipal acquisition in our history, receiving Kentucky and West Virginia regulatory approval of the Peoples transaction, and completing Pennsylvania’s rate proceeding to begin recovery of our infrastructure investment,” said Essential Chairman and CEO Christopher Franklin. “These accomplishments and the introduction of our new company name, Essential, have positioned us to play an important role in solving today’s infrastructure challenges and support our mission of delivering safe and reliable natural resources that are essential to everyday life.”

Fourth quarter 2019 operating results

Revenues increased to $226.0 million in the fourth quarter compared to $205.7 million in the same period of 2018, an increase of 9.9 percent. Rate and surcharges, volume and customer growth increased revenues.

Operations and maintenance expenses in the fourth quarter of 2019 were $85.3 million compared to $92.4 million in 2018. The Peoples-related transaction items in 2018 were the largest driver of this decrease.

For the fourth quarter 2019, Essential reported net income of $64.2 million (GAAP) or $0.28 per share (GAAP) compared to the net loss of $3.7 million (GAAP) or $0.02 per share (GAAP) for the fourth quarter of 2018. The increase in GAAP earnings was a result of increased rates and surcharges, a prior year mark-to-market adjustment on interest rate swaps and other transaction expenses related to the Peoples transaction in 2018. Excluding the impact of the Peoples transaction, adjusted income for the fourth quarter of 2019 was $61.4 million (non-GAAP) or $0.34 per share (non-GAAP), compared to $55.2 million (non-GAAP) or $0.31 (non-GAAP) in 2018. Please refer to the reconciliation of GAAP to non-GAAP financial measures later in this press release for additional information on Essential’s use of non-GAAP financial measures as a supplement to its GAAP results.

Dividend

On Jan. 31, 2020, Essential’s board of directors declared a quarterly cash dividend of $0.2343 per share of common stock. This dividend is payable on March 1, 2020, to all shareholders of record on Feb. 14, 2020. The March dividend marks the 75th year Essential has paid a consecutive quarterly dividend.

Water utility acquisition growth

In 2019, Essential invested $59.7 million to acquire eight water and wastewater systems. These acquisitions added approximately 12,000 new customers to the company’s operating footprint. Coupled with organic growth, the company increased its customer base by 2.1 percent with 21,114 new customer connections.

In December, Essential announced the completed acquisitions of the Cheltenham Township wastewater system for $50.25 million and the Phoenixville Borough water system for $3.5 million, both in Pennsylvania, and the Skyline water and wastewater systems for $3.5 million and the Village of Grant Park wastewater system for $2.3 million, all in Illinois. To date in 2020, the company also completed the purchase of the City of Campbell’s water system, which serves about 3,200 customer connections in Ohio, for $7.5 million.

The company currently has three signed purchase agreements for other municipal wastewater acquisitions that are expected to serve approximately 205,000 equivalent retail customers and add approximately $327 million in expected rate base upon closing. This includes a signed purchase agreement with DELCORA to acquire the municipal authority’s wastewater assets for $276.5 million. The pending transaction is subject to Pennsylvania Public Utility Commission approval. Essential estimates that DELCORA serves the equivalent of 198,000 retail customers. The customer base consists of retail, commercial and industrial customers and wholesale agreements with 42 municipal authorities in Southeast Pennsylvania. Its assets include 168 miles of combined and separate sewer mains, 14 miles of large-diameter force mains, and a 50-million gallon-per-day wastewater treatment plant. DELCORA will be the largest municipal transaction the company has ever completed.

The pipeline of potential water and wastewater municipal acquisitions the company is actively pursuing represents approximately 320,000 total customers. The company expects overall water and wastewater customer growth to be between 2 and 3 percent annually, depending upon regulatory approval.

Peoples acquisition regulatory update

Peoples is a natural gas distribution utility that serves over 746,000 customer connections in Western Pennsylvania, Kentucky and West Virginia. In March 2019, Essential received regulatory approval for the Peoples transaction from the Kentucky Public Service Commission, in April 2019, the company received approval from the West Virginia Public Service Commission, and in January 2020, the company received approval from the Pennsylvania Public Utility Commission. Essential now expects the Peoples acquisition will close on March 16, 2020.

Capital expenditures

In 2019, Essential invested a record $550 million to rehabilitate and improve its infrastructure systems. To replace and expand its water and wastewater utility infrastructure, Essential’s Aqua subsidiaries expect to invest approximately $550 million in 2020. The company expects to invest approximately $400 million in gas infrastructure in 2020. The capital investments made to rehabilitate and expand the infrastructure of the communities Essential serves are critical to its mission of delivering safe and reliable natural resources.

Rate activity

In 2019, the company’s Aqua subsidiaries in New Jersey, North Carolina, Ohio and Pennsylvania received rate awards or infrastructure surcharges totaling an estimated increase to annualized revenues of $58.2 million.

To date in 2020, the company’s Aqua subsidiaries in Illinois, Ohio and North Carolina have received rate awards or infrastructure surcharges totaling $4.8 million. Additionally, the company currently has rate proceedings pending in Indiana, New Jersey, North Carolina and Virginia totaling $8.3 million.

Reconciliation of GAAP to Non-GAAP Financial Measures

(In thousands, except per share amounts)

(Unaudited)

The Company is providing disclosure of the reconciliation of the non-GAAP financial measures to the most comparable GAAP financial measures. The Company believes that the non-GAAP financial measures “adjusted income” and “adjusted diluted income per common share” provide investors the ability to measure the Company’s financial operating performance by adjustment, which is more indicative of the Company’s ongoing performance and is more comparable to measures reported by other companies. The Company further believes that the presentation of these non-GAAP financial measures is useful to investors as a more meaningful way to compare the Company’s operating performance against its historical financial results.

This reconciliation includes a presentation of “adjusted income” and “adjusted diluted income per common share.” Both of these amounts are non-GAAP financial measures and have been adjusted to exclude the following:

(1) Transaction-related expenses for the Company’s pending Peoples acquisition, which consists of costs of $1,005 recorded as operations and maintenance expenses for the three months ended December 31, 2019 and $22,891 for the year ended December 31, 2019, primarily representing expenses associated with obtaining regulatory approvals, investment banking fees, legal expenses, and integration planning. Additionally, mark-to-market fair value adjustments of $23,742 for the year ended December 31, 2019 associated with our interest rate swap agreements for debt issued related to this transaction are included in transaction-related expenses. The interest rate swap agreements were settled on April 24, 2019, which coincided with the debt financings to partially fund the Peoples acquisition. Further, expenses of $19,433 for the year ended December 31, 2019 associated with the refinancing of existing debt that occurred in May 2019 are included in transaction-related expenses;

(2) Pre-acquisition interest expense of $4,684, net of interest income of $2,041 for the three months ended December 31, 2019 and $12,933, net of interest income of $6,972 for the year ended December 31, 2019, commencing in the second quarter of 2019 for funds borrowed for our pending acquisition of Peoples since the acquisition for which the funds were borrowed for is not yet complete;

(3) On April 26, 2019, the Company issued $313,500 of notes so as to complete an early extinguishment of $313,500 of existing debt on May 18, 2019. The Company incurred overlapping net interest expense during this 22-day period of $452, based on interest expense incurred of $858, net of interest income earned of $406;

(4) Interest income earned on the proceeds received from our April 2019 equity offerings of common shares and tangible equity units;

(5) The income tax impact of the non-GAAP adjustments described above; and

(6) The effect on average diluted shares outstanding of the shares issued in April 2019 for our common share and tangible equity unit issuances for our acquisition of Peoples since the acquisition for which the equity offerings were issued for is not yet complete.

These financial measures are measures of the Company’s operating performance that do not comply with U.S. generally accepted accounting principles (GAAP), and are thus considered to be “non-GAAP financial measures” under applicable Securities and Exchange Commission regulations. These non-GAAP financial measures are derived from our consolidated financial information, and should only be used as a supplement to our GAAP disclosures, and should not be considered as a substitute for measures of financial performance prepared in accordance with GAAP.

The following reconciles our GAAP results to the non-GAAP information we disclose :

Essential Utilities, Inc. and Subsidiaries

Reconciliation of GAAP to Non-GAAP Financial Measure

(Unaudited)

The Company is providing disclosure of the reconciliation of the Company’s outlook of the non-GAAP financial measure “adjusted diluted income per common share” to the most comparable GAAP financial measure “diluted net income per common share.” The diluted income per share guidance for 2020 assumes that the Peoples acquisition is completed in March 2020. The Company believes that the non-GAAP financial measure “adjusted diluted income per common share” for Essential’s 2020 full-year illustrative guidance provides investors the ability to measure the Company’s future financial operating performance with adjustments, by providing an estimate of the full-year effects of the Peoples acquisition as if this transaction closed on January 1, 2020. The adjusted results are more indicative of the Company’s future performance and are more comparable to measures reported by other companies. The Company believes that the presentation of this non-GAAP financial measure is more indicative of the Company’s future performance and is more comparable to measures reported by other companies.

This reconciliation includes a presentation of the non-GAAP financial measure “adjusted diluted income per common share” for Essential’s 2020 full-year guidance and has been adjusted for the following items:

(1) Excludes transaction-related expenses for the Company’s pending Peoples acquisition, which consists of costs primarily representing expenses associated with obtaining regulatory approvals, investment banking fees, legal expenses, and integration planning;

(2) Excludes the impact of Peoples transaction-related rate credits of $23 million to be granted to Pennsylvania water and gas customers;

(3) In order to illustrate the full-year 2020 effects of the Peoples acquisition as if this transaction closed on January 1, 2020, this adjustment includes both the estimated impact of Peoples Gas pre-tax operating results for the period in 2020 prior to closing, as well as the additional net interest expense expected to have been incurred for partially funding the estimated purchase price of Peoples;

(4) Excludes the income tax impact of the non-GAAP adjustments described above.

This financial measure is a measure of the Company’s operating performance that does not comply with U.S. generally accepted accounting principles (GAAP), and is thus considered to be a “non-GAAP financial measure” under applicable Securities and Exchange Commission regulations. The non-GAAP financial measure is provided to supplement the Company’s GAAP outlook and should not be considered as a substitute for measures of financial performance prepared in accordance with GAAP.
