Essential Utilities reports financial results for Q3 2020

Earns $0.22 per share (GAAP) and adjusted earnings per share of $0.23 (Non-GAAP)

Refines 2020 annual adjusted earnings guidance to the top end of the $1.53 to $1.58 range

Signs agreement with Lower Makefield for 11,000 customer connections

Publishes Environmental, Social and Governance (ESG) report

BRYN MAWR, Pa. – Essential Utilities Inc. (NYSE: WTRG), today reported results for the third quarter ended Sept. 30, 2020.

Company Highlights

“Our commitment to providing safe, reliable, affordable resources during these uncertain times has never been more important for our customers and the communities we serve,” said Essential Chairman and CEO Christopher Franklin. The company has made donations to several nonprofits to support communities in need and enhanced the low-income assistance program to ensure customers continue to receive its services.

“We are pleased to have published our 2019 Environmental, Social and Governance (ESG) report, highlighting our commitment to environmental stewardship, sustainable business practices, employee safety, diversity and inclusion, customer experience and community engagement. We look to bring the same ESG focus to the natural gas business as we expect to announce a companywide emissions reduction target in the next six months. We are also pleased that, due to the combined efforts across our 10-state footprint, we are able to refine our annual adjusted earnings per share guidance to the top end of the $1.53 to $1.58 range,” stated Franklin.

Operating Results

Essential reported net income of $55.7 million (GAAP) for the third quarter 2020, or $0.22 per share (GAAP), compared to $88.5 million, or $0.38 per share, for the third quarter 2019. Results for the third quarter of 2020 include the operating results of Peoples, which largely comprises the company’s regulated natural gas segment, and results for the third quarter of 2019 include Peoples transaction-

related items. Adjusting for transaction-related water rate credits issued to utility customers, adjusted net income in the third quarter of 2020 was $58.6 million (non-GAAP), or $0.23 per share (non-GAAP). 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.

Revenues for the quarter were $348.6 million, an increase of 43.1% compared to $243.6 million in the third quarter of 2019. The natural gas utility acquired in the first quarter contributed $92.1 million of this revenue growth, while the remainder was due to increased volume, growth and rate and surcharge increases in the regulated water segment. Adjusted revenues for the third quarter of 2020, which exclude water rate credits issued to utility customers, were $352.7 million (non-GAAP). Operations and maintenance expenses increased to $136.2 million for the third quarter of 2020 compared to $82.0 million in the third quarter of 2019. The increase in operations and maintenance expenses was primarily a result of operations and maintenance expenses of $62.2 million from the acquisition of Peoples.

The regulated water segment reported revenues for the quarter of $255.7 million, an increase of 5.3% compared to $242.9 million in the third quarter of 2019. Increased volume and rates and surcharges were the largest contributors to the increase in revenues for the period, in addition to customer growth from both organic growth and acquisitions. Operations and maintenance expenses for the regulated water segment decreased by 2.2% to $79.3 million for the third quarter of 2020.

The regulated natural gas segment reported revenues for the third quarter of 2020 of $88.9 million. Operations and maintenance for the same period for the regulated natural gas segment were $59.6 million and purchased gas costs were $14.8 million.

For the first nine months of 2020, the company reported revenues of $988.7 million compared to $663.7 million in the first nine months of 2019. Adjusted revenues for the first nine months, which exclude water rate credits issued to utility customers, were $992.8 million (non-GAAP). Operations and maintenance expenses for the first nine months of 2020 were $371.4 million compared to $247.8 million in 2019.

As of Sept. 30, 2020, Essential reported year-to-date net income of $182.1 million or $0.71 per share (GAAP) compared to $160.3 million or $0.76 per share (GAAP) reported through the same period of 2019. Adjusted income and adjusted income per share (both non-GAAP financial measures) for the first nine months of 2020, exclude the impact of both the Peoples transaction-related water rate credits issued to utility customers of $4.1 million and Peoples transaction-related expenses, and include a normalized pro forma adjustment for the Peoples operating results for the period Jan. 1, 2020 to March 15, 2020 to provide the basis for a 2020 full-year run rate of operating results. Adjusted income for the first nine months of 2020 was $286.9 million or $1.12 per share (non-GAAP). The fourth quarter of 2020 will include additional rate credits to be issued to gas utility customers of $18.9 million. 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 Oct. 21, 2020, Essential’s board of directors declared a quarterly cash dividend of $0.2507 per share of common stock. This dividend will be payable on Dec. 1, 2020 to shareholders of record on Nov. 13, 2020. The company has paid a consecutive quarterly cash dividend for more than 75 years.

Financing

In August, Essential announced an offering of 6.7 million shares of common stock via a forward equity sale agreement. The company will not receive any proceeds from the sale of our common stock by the forward purchaser until settlement of all or a portion of the agreement. If assuming full settlement today, the company would receive approximately $306 million in proceeds which are expected to be used to fund general corporate purposes, including the acquisition of the Delaware County Regional Water Quality Control Authority (DELCORA) and other water and wastewater acquisitions in its pipeline. The forward sale agreement allows the company to settle the transaction between now and Aug. 10, 2021.

Water utility acquisition growth

Essential’s continued acquisition growth allows the company to provide safe and reliable water and wastewater service to an even larger customer base. On October 8, 2020, the company’s regulated water segment subsidiary, Aqua Illinois, closed its acquisition of the Rockwell Utilities water and wastewater system, adding approximately $5.15 million in rate base. In the first nine months of 2020, customer growth for the company’s water utilities has totaled 1.5% including organic growth.

The company has signed purchase agreements for other municipal water and wastewater acquisitions that are expected to add the equivalent of over 212,000 water and wastewater retail customers and approximately $363 million in expected rate base. This includes the recently announced, signed purchase agreement to acquire the wastewater system of Lower Makefield, a Pennsylvania utility with approximately 11,000 customer connections and the previously announced, signed purchase agreement between Essential’s regulated water segment subsidiary, Aqua Pennsylvania Wastewater, and DELCORA.

“We remain focused on advancing the DELCORA acquisition, while continuing to partner with municipalities, like Lower Makefield, to provide the operational excellence that has become synonymous with our 134-year-old company,” added Franklin.

Capital expenditures

Essential invested $554.1 million in the first nine months of the year to improve its regulated water and natural gas infrastructure systems and to enhance its customer service across its operations. This does not include an additional $53.5 million that was invested by Peoples, pre-closing, during the period from Jan. 1, 2020 to March 15, 2020. The company remains on track to replace and expand its water and wastewater utility infrastructure by investing approximately $550 million in 2020. Additionally, the company expects to invest approximately $400 million in 2020 to replace and upgrade its natural gas utility infrastructure (including capital invested in 2020 prior to Essential’s ownership), leading to significant reductions in methane emissions that occur in aged gas pipes. In total, infrastructure investments of approximately $2.8 billion are expected through 2022 to improve water and natural gas systems (including capital invested at Peoples in 2020 prior to Essential’s ownership) and better serve our customers through improved information technology. The capital investments made to rehabilitate and expand the infrastructure of the communities Essential serves are critical to its mission of safely and reliably delivering Earth’s most essential resources.

Rate activity

To date in 2020, the regulated water segment has received rate awards or infrastructure surcharges in Illinois, Indiana, North Carolina, Ohio, Virginia and Pennsylvania totaling an estimated increase in annualized revenues of $21.0 million. Additionally, the regulated natural gas segment has received infrastructure surcharges in Kentucky and Pennsylvania totaling an estimated increase to annualized revenues of $1.0 million. The company currently has proceedings pending in New Jersey, Virginia and Indiana for its regulated water segment, which would add $2.9 million in incremental revenue.

Essential refines 2020 guidance

The company continues to monitor the effects of the COVID-19 pandemic on its customers, employees and the business and will update guidance impacts from the pandemic in the future if needed. At this time, the company’s updated 2020 full-year guidance is:

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 operating revenues,” “adjusted income,” and “adjusted 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 the non-GAAP financial measures “adjusted operating revenues,” “adjusted income,” and “adjusted income per common share” and have been adjusted for the following items:

(1) Transaction-related water rate credits issued to Pennsylvania utility customers in September 2020.

(2) Transaction-related expenses for the Company’s Peoples acquisition that closed on March 16, 2020, which consists of costs of $2,496 recorded as operations and maintenance expenses for the three months ended September 30, 2019 and $25,397 and $21,886 for the nine months ended September 30, 2020 and 2019, respectively, primarily representing expenses associated with investment banking fees, obtaining regulatory approvals, legal expenses, and integration planning. Additionally included in transaction-related expenses for the nine months ended September 30, 2019 are mark-to-market fair value adjustments of $23,742 associated with interest rate swap agreements for debt issued related to the Peoples transaction. 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 $871 for the three months ended September 30, 2019 and $19,825 for the nine months ended September 30, 2019 associated with the refinancing of existing debt that occurred in May 2019 are included in transaction-related expenses;

(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 from January 1, 2020 to March 15, 2020, as well as the additional net interest expense expected to have been incurred for partially funding the estimated purchase price of Peoples;

(4) Pre-acquisition interest expense of $4,757, net of interest income of $2,757, for the three months ended September 30, 2019 and $8,249, net of interest income of $4,931 for the nine months ended September 30, 2019, commencing in the second quarter of 2019 for funds borrowed prior to the completion of the Company’s Peoples acquisition on March 16, 2020;

(5) 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 interest expense during this 22-day period of $858, net of interest income earned of $406, on the borrowed funds, and considers this overlapping net interest expense of $452 to be a transaction-related expense;

(6) Interest income earned on the proceeds received from our April 2019 equity offerings of common shares and tangible equity units prior to the completion of the Company’s Peoples acquisition on March 16, 2020;

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

(8) The effect on average diluted shares outstanding of the shares issued in April 2019 for our common share and tangible equity unit issuances prior to the completion of the Company’s Peoples acquisition on March 16, 2020.

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, if available, and is provided to supplement the Company’s GAAP measures, 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 reflects the completion of the Peoples acquisition March 16, 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 of $25.6 million for the Company’s Peoples acquisition completed in March 2020, which consisted 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 $23.0 million granted to Pennsylvania water and gas customers, which includes $4.1 million of water rate credits issued to Pennsylvania utility customers in the third quarter of 2020;

(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 of $108.1 million 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 $38.4 million for 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.
