Following today's proposed final decision by the Connecticut Public Utilities Regulatory Authority (PURA) to approve the proposed sale of the Aquarion Water Company to the South Central Connecticut Regional Water Authority, Eversource Energy (NYSE:ES) issued the statement below from Eversource Executive Vice President, Chief Financial Officer and Treasurer John Moreira.

Today's proposed final decision in the Aquarion case is a constructive development, and Eversource is currently considering the conditions described in PURA's decision. The sale of Aquarion is not included in our 2026 guidance. As communicated with our fourth quarter 2025 earnings call, we have already taken preliminary, necessary steps to position Eversource for stability with or without the sale of Aquarion. These steps included the recent issuance of Junior Subordinated Notes, the filing of a rate case for Aquarion, and last October's $600 million debt issuance at the parent company. Our annual 2026 and long-term guidance assumed that Aquarion remains part of Eversource, and is unchanged with 2026 earnings projected between $4.80 and $4.95 per share, and a cumulative long-term earnings per share growth rate within the range of 5 to 7 percent through 2030 using the 2025 non-GAAP results of $4.76 per share earned as the base year. Aquarion is led by a top-tier management team with a top-quality asset base and operations profile. We await PURA's final decision which is scheduled to be released March 25. Closing the transaction may extend past March 25^th, and could require additional process.
