Insights

M&A Counsel

Regulatory approvals advancing; closing still conditional.

The Ohio order and earlier Kentucky approval show progress toward merger completion. The companies emphasize standard closing conditions, including Hart‑Scott‑Rodino clearance and other public utility commission approvals, which remain outstanding.

Completion depends on satisfying those conditions; subsequent filings and regulatory orders will specify any conditions or divestitures required. Parties should disclose material regulatory conditions in future SEC filings.

Regulatory Affairs Analyst

Two state approvals secured; multi‑jurisdiction review continues.

The communication notes PUCO approval (May 14, 2026) and Kentucky approval (April 21, 2026), and cites remaining approvals from other public utility commissions. The transaction remains subject to review under federal merger control (Hart‑Scott‑Rodino Act).

Regulatory timing and any imposed conditions will determine the ultimate closing timeline; investors should watch for additional commission orders and the parties' SEC filings for material conditions or remedies.

A public utility commission is a government agency that regulates providers of essential services such as electricity, gas, water and telecommunications by approving rates, service standards and major investments. Think of it as a referee and budget overseer for utilities—its decisions determine how much customers pay and which projects companies can build, so rulings directly affect revenue, profits and investment risk for shareholders.
