CENTERPOINT ENERGY INC (CNP) stock intrinsic value fair value estimate & owner earnings analysis

CenterPoint Energy is the regulated electric transmission and distribution utility serving the Houston, Texas metropolitan area, plus regulated natural gas distribution utilities in Indiana, Ohio and Minnesota. Over the past several years the company has simplified itself into these two core, government-regulated franchises — selling off its stake in the Enable Midstream pipeline business, its non-utility Energy Systems Group unit, and several smaller gas utilities — so that essentially all of its earnings now come from assets that operate under a regulated return on invested capital. The company is in the middle of a large, multi-year build-out of its regulated asset base: net utility plant grew from about $23.5 billion at the end of 2021 to about $34.1 billion at the end of 2025, a roughly 10% annual pace. That growth is real and it is what drives the company's future earning power, but it is being funded mostly with new debt and new shares rather than out of the cash the business throws off today — the share count has grown by roughly half since 2017. That is normal for a utility mid-way through a large capital program, but it means the cash available to today's shareholders, after the spending needed just to keep the existing system running, is fairly thin right now relative to the size of the company. Cash flow in this business has also been genuinely lumpy for a specific, identifiable reason: Winter Storm Uri in February 2021 forced the Texas gas utility to spend heavily on natural gas that it could not immediately bill back to customers, which is recovered later through a regulatory mechanism (in some cases via securitized bonds). That single event nearly wiped out reported operating cash flow in 2021 and then inflated it again as the deferred cost was recovered in 2023. We treated both of those years as one-time distortions and anchored the valuation on the more representative years around them (2022, 2024 and 2025), which put normalized owner earnings at roughly $1 per share today. We do not extrapolate the sharp jump seen in 2025's cash flow into the future; the growth path we use starts well below that pace and is tied instead to the pace of the company's actual regulated investment program. A judgment call worth noting: because so much of this company's revenue is simply the pass-through cost of the natural gas it buys for customers, revenue is not a reliable yardstick for separating spending that merely maintains the existing system from spending that grows it. We instead used depreciation — a more standard measure of how fast the existing asset base wears out — as the estimate of maintenance-level spending, with the remainder of each year's capital spending counted as growth investment. Base case: the regulated investment program continues at roughly the pace it has run since 2021, growing per-share owner earnings by about 6-7% a year over the next several years, tapering toward the mid-single digits as the current capital program matures and the company relies less on issuing new shares to fund it. Beyond the explicit ten-year forecast, we assume growth settles at a modest, inflation-and-population-linked pace, consistent with a franchise that has operated continuously in a growing service area for decades — not a continuation of the current elevated build-out forever. Bear case: the two big weather events of the last five years — Winter Storm Uri in 2021 and Hurricane Beryl in 2024, which caused extended outages across the Houston area — show that large, cash-disruptive storm events are a recurring feature of this service territory, not a one-off. We also see the pace of growth in the company's actual rate base slowing even as cash capital spending keeps rising (net plant grew by only about $2 billion in 2025 versus roughly $3.7 billion in 2022, on a larger spending total), a sign that some recent spending may not yet be earning a return. Combined with a debt load that has risen steadily to fund the buildout, the bear case assumes per-share owner earnings grow only slightly, near flat, with heavier reliance on new shares to keep the balance sheet sound. Bull case: the same investment program executes at the faster end of what it has already demonstrated (closer to the 2022-2023 pace of rate-base growth) while cash generation keeps improving the way it has in 2024 and 2025, reducing the need for further share issuance and letting more of the earnings growth flow through to existing shareholders. Putting this together, we get roughly $22 per share in the bear case, $44 per share in the base case, and $49 per share in the bull case. Given the real leverage and storm-related cash-timing risk in this business — more than a bond-like utility, but still a well-established, essential-service monopoly franchise — the margin-of-safety price sits meaningfully below the base-case estimate, around $30 per share, to leave room for results closer to the bear case. One limitation: a couple of smaller items — stock-based compensation expense and the exact working-capital detail behind the 2021/2023 cash swings — were not separately broken out in the data available to us for recent years and were estimated from the reported totals and other disclosed figures. Both are a small share of the total and do not change the overall picture.
