Eversource Energy Reports Full-Year Results

Announces Exploration of Sale of Water Distribution Business

HARTFORD, Conn. and BOSTON, Mass. (February 13, 2024) – Eversource Energy (NYSE: ES) today reported a full-year 2023 loss of $(442.2) million, or $(1.26) per share, compared with full-year 2022 earnings of $1,404.9 million, or $4.05 per share. Eversource also reported a fourth quarter 2023 loss of $(1,288.5) million, or $(3.68) per share, compared with fourth quarter 2022 earnings of $320.2 million, or $0.92 per share.

Results for the full year and the fourth quarter of 2023 include after-tax impairment charges of $1,953 million, or $5.58 per share, and $1,622 million, or $4.63 per share, respectively, related to Eversource Energy’s offshore wind investment. In addition, results for both years include other after-tax non-recurring costs and charges that totaled $6.9 million for the full year of 2023 compared with $15 million for the full year of 2022.

2023 Non-GAAP EPS of $4.34 – Focus on Core Electric and Natural Gas Distribution and Transmission Businesses

Excluding the charges noted above, Eversource Energy reported non-GAAP earnings of $1,517.7 million¹, or $4.34 per share¹, for the full-year 2023 and $333.5 million¹, or $0.95 per share¹, in the fourth quarter of 2023, compared with $1,419.9 million¹, or $4.09 per share¹, for the full-year 2022 and $322.3 million¹, or $0.92 per share¹, in the fourth quarter of 2022. Eversource’s core distribution and transmission businesses are well positioned to deliver solid operational and financial results as we move forward in supporting the region’s transition to a cleaner energy environment.

Full Exit of Offshore Wind Business

With the announcement today of the sale of South Fork Wind and Revolution Wind to Global Infrastructure Partners, the agreement reached with Ørsted for the sale of Sunrise Wind and the completed sale of the uncommitted lease area last year, we now have the pathway to a full exit of Eversource’s offshore wind business. Eversource will continue to hold its existing tax equity investment in South Fork Wind.

Potential Sale of Water Distribution Business

Eversource’s water distribution business segment comprises a set of valuable, well-performing and well managed assets. Although the business has been earnings accretive to Eversource, a potential sale of the water business is an opportunity to reduce equity needs and improve regulatory diversity. With its $1.3 billion rate base as of December 31, 2023, the water business is likely of substantial value to another owner as part of a larger strategic water business or infrastructure platform. As a result, Eversource plans to launch a process evaluating market interest in a transaction for this business segment, with the objective of delivering greater value to all stakeholders. Eversource cannot provide assurances regarding the ultimate outcome or the timing around this process.

“Aquarion has been a meaningful investment to Eversource, and I appreciate the hard work and dedication of the Aquarion team and its leadership. The company is well recognized and respected for its operational excellence in the water distribution business,” said Joe Nolan, Eversource Energy Chairman, President and Chief Executive Officer. “The Aquarion team truly shares the Eversource values of customer commitment and stewardship of the environment.”

Eversource Energy is focused on building the necessary transmission and distribution infrastructure for the clean energy future that its customers and states desire. We continue to work constructively with stakeholders to improve the regulatory environment in Connecticut to provide customers with a high level of safe, reliable and cost-effective investments.

Also today, Eversource Energy projected 2024 non-GAAP earnings of between $4.50 per share and $4.67 per share. The Company also projected that its compound annual earnings per share growth rate from its regulated businesses would be within the range of 5 to 7 percent through 2028, using the adjusted $4.34 per share¹ earned in 2023 as the base year. Eversource anticipates its equity issuances of up to $1.3 billion over the next several years, in combination with the potential sale of its water distribution business segment.

“Although we experienced great challenges over the past year, our core utility operations completed an excellent year owing to the dedication of our 10,000 employees in providing safe and reliable service to our 4.4 million customers,” said Nolan. “Our focus remains on improving our already strong service metrics, making the required investments to modernize the region’s energy delivery system and enabling our clean energy future while enhancing our balance sheet condition.”

Electric Transmission

Eversource Energy’s transmission segment earned $643.4 million in 2023, compared with earnings of $596.6 million in 2022. Transmission earnings were $167 million in the fourth quarter of 2023, compared with earnings of $140.7 million in the fourth quarter of 2022. Transmission segment results improved due to a higher level of investment in Eversource’s electric transmission system.

Electric Distribution

Eversource Energy’s electric distribution segment earned $608 million in 2023, compared with earnings of $592.8 million in 2022. Electric distribution earned $103.7 million in the fourth quarter of 2023, compared with earnings of $97.9 million in the fourth quarter of 2022. Improved full-year and fourth-quarter results were due primarily to higher revenues from investments in our distribution system and a base distribution rate increase for Eversource’s Massachusetts electric business, partially offset by higher operations and maintenance (O&M), interest expense, property taxes and depreciation. Fourth-quarter results also included the benefit of a seasonal rate design impact in Massachusetts that has no impact on annual results.

Natural Gas Distribution

Eversource Energy’s natural gas distribution segment earned $224.8 million in 2023, compared with earnings of $234.2 million in 2022. It earned $76.5 million in the fourth quarter of 2023, compared with earnings of $87.1 million in the fourth quarter of 2022. Lower full-year results were due primarily to higher depreciation, interest expense, and a higher effective tax rate, partially offset by higher revenues. Lower fourth-quarter results were due primarily to higher O&M and depreciation expense, partially offset by higher revenues.

Water Distribution

Eversource Energy’s water distribution segment earned $33.1 million in 2023, compared with earnings of $36.8 million in 2022. The water distribution segment earned $5.7 million in the fourth quarter of 2023, compared with earnings of $7.4 million in the fourth quarter of 2022. Lower full-year and fourth-quarter results were due primarily to higher depreciation, O&M and interest expense.

Eversource Parent and Other Companies

Eversource Energy parent and other companies earned $8.4 million¹ in 2023, compared with a loss of $(40.5) million¹ in 2022. It lost $(19.4) million¹ in the fourth quarter of 2023, compared with a loss of $(12.9) million¹ in the fourth quarter of 2022. Improved full-year results primarily reflect a lower effective tax rate and a benefit from the disposition of Eversource’s interest in a clean energy fund and a resultant contribution in the first quarter of 2023 to the Eversource Energy Foundation, partially offset by higher interest expense. Lower fourth-quarter results were due primarily to higher interest expense, partially offset by a lower effective tax rate.

The following table reconciles 2023 and 2022 fourth quarter and full-year GAAP earnings per share:
