EVERSOURCE ENERGY

Eversource Energy’s shares trade publicly on the New York Stock Exchange under the ticker ES, so its shareholder base reflects the wide public float typical of a large listed utility rather than a fixed private shareholder register. The information reviewed lists ten disclosed shareholders as of 4 September 2026, all holding ordinary shares. The five largest are Vanguard Index Funds’ Vanguard 500 Index Fund (approximately 4.05%), iShares Trust’s iShares Select Dividend ETF (approximately 2.23%), iShares Trust’s iShares Core S&P 500 ETF (approximately 2.14%), the SPDR S&P 500 ETF Trust (approximately 2.00%) and State Street’s SPDR S&P Dividend ETF (approximately 1.55%). Together these five holdings represent roughly 12% of shares outstanding, and each appears to be a direct holding rather than part of a disclosed indirect chain.

Every disclosed shareholder is an investment fund rather than a natural person, so no ultimate beneficial owner can be identified from this information, and none should be assumed. Passive index and exchange-traded funds of this kind are diversified investment vehicles rather than controlling corporate shareholders, and none of the disclosed holdings approaches a level that would typically indicate control.

This is best treated as a major-shareholders-only disclosure: it reflects the largest identified institutional positions rather than a complete shareholder register, which for a company of Eversource Energy’s size and New York Stock Exchange listing would include a very large number of individual and institutional holders of record and beneficial owners not captured here. The absence of a verified ultimate beneficial owner should not be read as evidence that none exists, only that ownership is dispersed across public markets.

The officer information reviewed for Eversource Energy shows 17 officer records, of which the five most senior shown here are all listed as currently active. As a Massachusetts voluntary association, Eversource Energy is governed by a Board of Trustees rather than a conventional board of directors. Joseph R. Nolan, Jr. holds the combined roles of Chairman of the Board, President and Chief Executive Officer, and is also a Trustee. Other current senior officers include John M. Moreira, Executive Vice President, Chief Financial Officer and Treasurer; Penelope McLean-Conner, Executive Vice President of Customer Experience and Energy Strategy; Jeffrey R. Kotkin, Vice President of Investor Relations; and James A. Muntz, President of Transmission.

Nationality is not officially disclosed for any of these officers in the sources reviewed and should not be inferred from a person’s name. The “US” country field recorded against each officer reflects an address or filing jurisdiction rather than confirmed nationality or country of residence, and any correspondence address on file is a company service address, not a personal residential address.

Recent verified changes: Joseph R. Nolan, Jr. was promoted from Executive Vice President to President and Chief Executive Officer effective 5 May 2021, and became Chairman of the Board effective 1 January 2023, succeeding Jim Judge. John M. Moreira became Chief Financial Officer, while retaining his role as Treasurer, effective May 2019. Separately, W. Robert Mudge was elected to Eversource Energy’s Board of Trustees effective 1 January 2026.

Officer information for a New York Stock Exchange-listed company such as Eversource Energy is disclosed through SEC filings and official company announcements rather than a central public officer register. The information above reflects the company’s most recent disclosures reviewed and should be treated as current rather than exhaustive or historical.

Eversource Energy sits at the top of its own corporate group rather than being controlled by another company: the corporate-linkage data reviewed shows no parent or ultimate parent above it, consistent with its status as a New York Stock Exchange-listed public company. Beneath it, the group has historically comprised roughly three dozen direct and indirect subsidiaries, almost all incorporated in Massachusetts, Connecticut or New Hampshire, the three states where Eversource Energy’s regulated electric and natural gas utilities operate. Known direct or indirect subsidiaries include The Connecticut Light and Power Company, NSTAR Electric Company, NSTAR Gas Company, Public Service Company of New Hampshire and Western Massachusetts Electric Company, each a regulated utility operating company; ownership percentages for these entities were not disclosed in the sources reviewed.

The corporate-linkage data reviewed still lists Aquarion Water Company and its related water-utility entities, including Aquarion Water Company of Connecticut, Aquarion Water Company of Massachusetts and Aquarion Water Company of New Hampshire, as part of the group. This is outdated. According to Eversource Energy’s own SEC filing and investor announcement, the company completed the $2.4 billion cash sale of Aquarion Water Company to the Aquarion Water Authority, a quasi-public corporation and political subdivision of the State of Connecticut, on 30 June 2026. Aquarion Water Company and its related entities should therefore be treated as a historical relationship that ended on that date, not as current subsidiaries of Eversource Energy.

Data availability: the underlying corporate-structure information is best described as partial, and for the water-utility entities specifically as historical, since it identifies parent-subsidiary relationships but not ownership or voting percentages, and it has not been updated to reflect the completed Aquarion divestment. No other verified acquisitions, disposals or reorganisations beyond the Aquarion sale were identified in the sources reviewed.
