Eversource Energy filed a Post-Effective Amendment No. 1 to its Form S-3 to add junior subordinated notes as a class of securities registered under the existing shelf registration.
The prospectus states these securities may be offered from time to time after the effective date, with terms and amounts to be set in prospectus supplements.
Eversource Energy and its utility subsidiaries file a combined annual report describing a large regulated energy and water business across Connecticut, Massachusetts and New Hampshire. The company delivers electricity through CL&P, NSTAR Electric and PSNH, distributes natural gas via NSTAR Gas, EGMA and Yankee Gas, and provides water service through Aquarion’s utilities.
Eversource reports four main segments: electric distribution, electric transmission, natural gas distribution and water distribution, which together represent nearly all consolidated revenue. The filing explains detailed state-specific rate structures where regulators set tariffs that separately recover supply, delivery, public-benefit and infrastructure costs, often with annual true-ups and revenue decoupling mechanisms.
The report highlights a roughly $11.3 billion electric transmission rate base at year-end 2025, ongoing FERC proceedings over allowable transmission returns on equity, and extensive environmental and climate regulation. Eversource outlines climate targets, including a 45% reduction in Scope 1 and 2 emissions by 2035 and net-zero across Scopes 1–3 by 2050, and discusses system resiliency, safety performance and a 10,731-person workforce, about half represented by unions.
Eversource Energy reported a strong rebound in 2025 results, with GAAP earnings of $1.69 billion, or $4.56 per share, up from $811.7 million, or $2.27 per share, in 2024. Non-GAAP recurring earnings rose to $1.77 billion, or $4.76 per share, compared with $1.63 billion, or $4.57 per share, the prior year, reflecting growth after excluding large offshore wind and Aquarion-related losses.
Fourth-quarter 2025 earnings were $421.3 million, or $1.12 per share, versus $72.5 million, or $0.20 per share, in 2024, helped by the absence of prior-year charges and better underlying performance in natural gas and electric distribution. For 2025, transmission earned $776.7 million, electric distribution $667.1 million, natural gas distribution $360.5 million and water distribution $44.2 million.
The company issued 2026 EPS guidance of $4.80–$4.95 per share and targets 5–7 percent long-term earnings-per-share growth through 2030, based on 2025 non-GAAP EPS. Eversource outlined a $26.5 billion capital investment plan for 2026–2030 and expects to raise $800 million to $1.1 billion of equity over that period while maintaining credit metrics above downgrade thresholds.
Eversource Energy and its utility subsidiaries updated their Code of Ethics for Senior Financial Officers, effective January 27, 2026. The boards approved an Amended and Restated Code that modernizes descriptions of auditor oversight and compliance programs and makes clarifying, stylistic, non-substantive revisions.
The updated code now explicitly assigns ongoing oversight responsibility to the Audit Committee, aligning with current best practices. The company states that responsibilities and obligations for senior financial officers are not materially changed and no waivers of the prior code were granted. The full text is available on Eversource Energy’s investor relations website.
