Divestiture of Ohio natural gas LDC business (CenterPoint Energy and CERC)

On October 1, 2026, CenterPoint Energy and CERC completed the previously announced sale of all of the issued and outstanding equity interests in CEOH, pursuant to the Ohio Securities Purchase Agreement, for $2.62 billion, subject to adjustment as set forth in the Ohio Securities Purchase Agreement. The purchase price was $2.62 billion, which was comprised of the following: (i) $1.42 billion in cash payable to CERC Corp. upon closing of the transaction, subject to adjustments as set forth in the Ohio Securities Purchase Agreement, including adjustments based on net working capital, regulatory assets and liabilities and capital expenditures at closing of the transaction; and (ii) a promissory note issued by NFGC in the original principal amount of $1.20 billion. The promissory note bears interest at a rate of 6.50% per annum and will mature on September 30, 2027. Goodwill of $393 million and $219 million was allocated to CEOH by CenterPoint Energy and CERC, respectively, at the time the held for sale criteria were met and such amounts were subsequently derecognized following the completion of the sale on October 1, 2026. CenterPoint Energy and CERC will recognize the financial impact of the divestiture in the fourth quarter of 2026. The financial impact cannot be reasonably estimated at this time as certain post-closing adjustments and other transaction-related amounts have not yet been finalized.
