CENTERPOINT ENERGY INC (CNP)

CenterPoint Energy, Inc. is a public utility holding company whose operating subsidiaries own and operate electric transmission, distribution and generation facilities and natural gas distribution systems. The filing is a combined Form 10-K for CenterPoint Energy, CenterPoint Energy Houston Electric, LLC and CenterPoint Energy Resources Corp. (CERC). Its principal operating subsidiaries are Houston Electric, CERC Corp. and SIGECO.

CenterPoint Energy reports three segments: Electric, Natural Gas, and Corporate and Other. The Electric segment combines Houston Electric and Indiana Electric. Houston Electric is a transmission and distribution utility operating wholly in Texas. It delivers power for retail electric providers (REPs) and builds and maintains transmission and distribution facilities under PUCT-approved tariffs. It does not sell electricity at retail or wholesale and owns no generation other than temporary emergency electric energy facilities (TEEEF). Indiana Electric is SIGECO's vertically integrated electric business, with generation, transmission and distribution. It sells into the MISO market and buys coal, wind and solar power under long-term supply and power purchase agreements. In 2025 SIGECO acquired Posey Solar, which was building a 191 MW solar array in Indiana. The Natural Gas segment, through CERC and SIGECO, provides regulated intrastate gas sales, transportation and storage. It also has pipeline interconnects through CEIP, and it has offered appliance repair, HVAC sales and home repair protection plans. In 2025 CERC Corp. sold its Louisiana and Mississippi gas distribution businesses for about $1.2 billion. It also agreed to sell its Ohio gas business (CEOH) for about $2.62 billion, with closing expected in the fourth quarter of 2026.

Houston Electric serves nearly all of the Houston/Galveston area on the Texas Gulf Coast. At year-end 2025 its service area had 67 REPs and about 2.86 million metered customers, mostly residential. Its direct customers are REPs plus municipalities, cooperatives and other distribution companies. It has no long-term customer contracts and bills REPs on a continuous cycle. Indiana Electric serves about 154,000 electric customers near Evansville in southwestern Indiana. The natural gas business serves about 4.03 million customers across Texas, Minnesota, Indiana and Ohio, with the largest metropolitan areas being Houston, Minneapolis, Evansville and Dayton. Commercial, industrial and transportation customers account for about two-thirds of gas throughput, and residential customers about one-third. Revenues are seasonal, rising with cooling demand in electric service and with both cooling and heating demand in Indiana.

The utilities operate under regulation by the PUCT, the IURC and municipal authorities, and Houston Electric holds non-exclusive municipal franchises. Houston Electric has no other transmission and distribution utility competing in its territory, and Indiana service territory certificates are exclusive. Distributed generation has not been a significant factor so far. Indiana Electric's coal comes entirely from Sunrise LLC, and it holds a 1.5% interest in OVEC. It operates under MISO control and NERC reliability standards. The registrants' principal executive offices are at 1111 Louisiana Street, Houston, Texas.
