Key Highlights

  • American Electric Power is the largest of the five, with a market Capitalization near $67.1 billion and direct Leverage to AI-driven load growth.
  • Xcel Energy trades near $75.50 a share with a market cap around $47.2 billion and a Dividend Yield near 3.1%.
  • York Water holds the oldest continuous dividend record in the United States, stretching back to 1816, despite being the smallest name here.
  • Middlesex Water is a small-cap water Utility carrying its own PFAS-related contamination exposure alongside steady regulated returns.

The Nasdaq Composite is usually shorthand for technology and growth. Yet the same index quietly houses a group of regulated electric and water utilities that are riding one of the most powerful Demand stories in a generation: the electricity needed to run artificial-intelligence data centres. Five of them, Xcel Energy (NASDAQ:XEL), Evergy (NASDAQ:EVRG), Middlesex Water (NASDAQ:MSEX), American Electric Power (NASDAQ:AEP) and York Water (NASDAQ:YORW), span the full range from a $67 billion multi-state electric giant to a small-cap Pennsylvania water company. Each is Nasdaq-listed, so each is a Nasdaq Composite constituent. Together they show how "boring" regulated utilities are being repriced by AI-era load growth, heavy capital plans and the market's shifting view on interest rates. Here is what the filings and disclosures actually say heading into autumn 2026.

The Sector Backdrop: AI Load, Big Capex and Rate-Case Reality

Two forces dominate US utility investing in 2026. The first is demand. After roughly two decades of flat US electricity consumption, load forecasts have turned sharply higher, driven by data centres, electrification and domestic manufacturing. That reverses the sector's old "no-growth" reputation and gives regulated utilities a credible path to grow their rate base, the asset value on which they earn a regulated return.

The second force is capital. Meeting new demand requires enormous spending on transmission, distribution and generation. Utilities fund that through Debt and equity, which makes them sensitive to interest rates: higher rates raise financing costs and make bond-like dividend yields less attractive, while a friendlier rate environment tends to support utility valuations. Every dollar of that plan must still clear a regulator in a rate case, where affordability and allowed returns are negotiated. The companies below sit at different points on this spectrum, from AEP's continent-scale build-out to York Water's small, steady Pennsylvania footprint.

Xcel Energy (NASDAQ:XEL): Clean-Energy Scale Meets Load Growth

Xcel Energy is one of the larger names in the group. As of the 11 September 2026 close, the stock traded around $75.50, with a Market Capitalisation near $47.2 billion, a dividend yield around 3.1% and a P/E near 20.7, according to market data.

Xcel reported full-year 2025 Revenue of roughly $14.67 billion and Net Income near $2.0 billion, for reported EPS of about $3.42; trailing-twelve-month EPS through June 2026 stood near $3.65. For 2026, Xcel's investor materials reiterate ongoing EPS guidance of $4.04 to $4.16, against a consensus near $4.11. The company frames its financial model around long-term EPS growth of 6% to 8%-plus, annual dividend increases of 4% to 6%, and a Payout Ratio target of 45% to 55%.

Xcel operates across states such as Colorado, Minnesota and Texas, giving it exposure to renewables build-out and rising commercial load. Eighteen analysts tracked carry an average "Strong Buy" view and a twelve-month price target near $91.76, an implied premium that reflects forecast, not fact. Watch execution on wildfire-related liabilities and rate-case outcomes, both of which can move the story.

Evergy (NASDAQ:EVRG): A Data-Centre Pipeline in the Plains

Evergy, the Kansas-and-Missouri utility, closed near $81.62 on 11 September 2026, with a market cap around $18.8 billion, a dividend near $2.78 a share for a yield around 3.4%, and a P/E near 20.8.

The company reported 2025 revenue of about $5.96 billion and net income near $856 million, with reported EPS of roughly $3.66; trailing EPS through mid-2026 was near $3.92. In its 6 August 2026 update, Evergy guided to 2026 adjusted EPS of $4.14 to $4.34, a midpoint of about $4.24, and reiterated a Long-term Growth target of 6% to 8%-plus through 2030, with growth expected to exceed 8% from 2028 onward as its capital plan ramps. Evergy has outlined a capital-expenditure plan of about $21.6 billion through 2030.

The most watchable catalyst is large-load demand. Evergy has pointed to a robust pipeline of data-centre projects and, in the first quarter of 2026, signed an electric service agreement for a large customer project. If that pipeline converts into signed load, it supports the case for capex and rate-base growth above the current plan. Thirteen analysts hold a "Buy" consensus with an average target near $91.27, a forecast to treat with the usual caution.

Middlesex Water (NASDAQ:MSEX): Small-Cap Water With a PFAS Twist

Middlesex Water is a different animal: a small-cap New Jersey and Delaware water utility. Shares closed near $56.69 on 11 September 2026, giving a market cap around $1.07 billion, a yield near 2.5% on a $1.44 annual dividend ($0.36 quarterly), and a P/E near 21.9.

The company reported 2025 revenue of about $194.7 million and net income near $42.8 million, for EPS of roughly $2.36; trailing EPS through mid-2026 was near $2.59. For the second quarter of 2026, reported on 30 July, Middlesex posted diluted EPS of $0.79.

Two 2026 developments give the story texture. In January, Middlesex's Delaware Subsidiary Tidewater completed the Acquisition of the Pinewood Acres water system, a small bolt-on that fits the water sector's steady consolidation of municipal and private systems. And on 31 August, Tidewater announced a second customer bill Credit funded by PFAS ("forever chemicals") litigation proceeds, a reminder that water utilities carry both the cost and, occasionally, the recovery upside of contamination issues. Coverage is thin, but the two analysts covering the stock hold a "Buy" view near a $61 target, with individual notes from Baird and Huntington higher. Water utilities trade as defensive, rate-base compounders; the trade-off is a modest yield and premium multiple.

American Electric Power (NASDAQ:AEP): The Load-Growth Heavyweight

American Electric Power is the giant of this group, and, importantly for the headline, it is Nasdaq-listed, so it is a Nasdaq Composite member. Shares closed near $123.33 on 11 September 2026, with a market cap around $67.1 billion, a yield near 3.1% on an annualised dividend of about $3.80, and a P/E near 21.4.

AEP reported 2025 revenue of roughly $21.9 billion and reported EPS near $6.66. In its 30 July 2026 release the company raised full-year 2026 operating EPS guidance to $6.25 to $6.55 (operating figures differ from GAAP), and it targets long-term growth of 7% to 9%. The scale of the build-out is the headline: AEP has outlined a five-year, roughly $78 billion capital plan through 2030 and expanded expected new load additions to about 69 gigawatts through 2030, backed by signed agreements and, it says, up to $16 billion in expected cost offsets from that load growth. It has secured roughly 13 GW of gas-fired turbine capacity to meet demand, and its Texas unit obtained up to $3.26 billion in US Department of Energy loans for grid work.

The risk sits alongside the opportunity: funding an $78 billion plan pressures the Balance Sheet and invites Equity issuance, while rate cases, including an Indiana Michigan Power affordability plan advanced in August 2026, test how much cost customers absorb. Twenty-three analysts average a "Buy" and a target near $144.

York Water (NASDAQ:YORW): The Oldest Dividend in America

York Water is the smallest name here and one of the most storied. The Pennsylvania water utility, widely documented as the oldest investor-owned utility in the United States with a continuous dividend record stretching back to 1816, closed near $33.13 on 11 September 2026, a market cap around $538 million, a yield near 2.8% on a $0.91 annual dividend, and a P/E near 20.6.

York reported 2025 revenue of about $77.5 million and net income near $20.1 million, for EPS of roughly $1.39; trailing EPS through mid-2026 was near $1.61. It reported second-quarter 2026 results on 6 August. Two items matter for the forward view. First, York completed a public common-stock offering in April 2026, a routine but dilutive way small water utilities fund their systems. Second, the company filed a rate request with the Pennsylvania Public Utility Commission on 30 May 2025 based on roughly $145 million in investment, the mechanism by which that spending eventually flows into revenue. Analyst coverage is light; recent initiations include Huntington at "Outperform" with a $35 target and Freedom Capital at "Hold" near $34. York is a classic low-drama, rate-base-and-dividend compounder whose fortunes hinge on regulatory approvals and acquisition pace.

What Investors Should Watch

Three threads run through all five names. Rate cases come first: allowed returns and affordability rulings in Colorado, Kansas, Missouri, Indiana, New Jersey and Pennsylvania decide whether announced capital plans actually earn. Large-load conversion comes second, the gap between a data-centre "pipeline" and a signed, energised contract is where Evergy and AEP will be judged. Interest rates come third: as regulated, capital-hungry, dividend-paying businesses, every company here is sensitive to financing costs and to how income investors price yield. Watch balance-sheet management too, since AEP's scale and York's small-cap equity raises both point to ongoing funding needs.

Utilities Quietly Riding the AI Power Trade

All five, XEL, EVRG, MSEX, AEP and YORW, are verified Nasdaq-listed common stocks and therefore Nasdaq Composite constituents, which is why a technology-flavoured index is quietly a venue for utilities and power. The electric names offer leverage to AI-era load growth and larger capital plans; the water names offer defensive, steadier compounding. None is a technology stock in disguise, and every forward figure here is guidance or estimate, not a promise. The through-line is regulated growth funded by heavy spending, powerful when regulators cooperate and rates behave, and vulnerable when they do not.
