Business Model
What each company does and how it makes money
Edison International is a regulated electric utility that generates, transmits, and distributes electricity to approximately 15 million customers across Southern California. It makes money primarily through regulated rate-based operations — earning a return on its capital investments in power generation, transmission, and distribution infrastructure — with its Southern California Edison subsidiary contributing the vast majority of revenue. The company's key advantage is its regulated monopoly status in its service territory, providing stable cash flows through authorized returns on its massive infrastructure investments.
National Grid is a regulated utility that operates electricity and gas transmission and distribution networks in the UK and northeastern United States. It earns revenue through regulated asset returns — collecting fees from customers for using its infrastructure — with its UK transmission business contributing roughly 40% of operating profit and its US operations about 35%. The company's primary moat comes from its natural monopoly position as an owner of critical energy infrastructure, protected by high regulatory barriers to entry and long-term, stable rate-of-return frameworks.
Exelon is a major regulated electric utility that operates one of the largest clean energy generation fleets in the U.S., primarily from nuclear power. It makes money through regulated electricity distribution and transmission services—which provide stable cash flows—and wholesale power generation from its nuclear, renewable, and fossil fuel plants. Its key advantage is its massive scale as the largest nuclear operator in the U.S., giving it cost advantages and regulatory expertise in clean energy markets.
FirstEnergy is a regulated electric utility that generates, transmits, and distributes electricity to approximately 6 million customers across six Mid-Atlantic and Midwestern states. It makes money primarily through regulated rate structures — with its distribution segment contributing about 60% of revenue and transmission about 40% — earning a government-approved return on its infrastructure investments. Its key advantage is its monopoly-like position as a regulated utility with exclusive service territories, providing stable cash flows through cost-plus regulation.
Empresa Distribuidora y Comercializadora Norte Sociedad Anónima is an Argentine electricity distribution utility that operates regulated power networks in northern Buenos Aires. It generates revenue primarily through regulated electricity distribution tariffs — which account for the vast majority of its income — with additional income from connection fees and commercial electricity sales. Its key competitive advantage is its government-granted monopoly over electricity distribution in its exclusive service territory, creating a stable, regulated revenue stream.

EIX vs NGG vs EXC vs FE vs EDN: Key Questions Answered
9 questions · data-driven answers · updated daily
01Is EIX or NGG or EXC or FE or EDN a better buy right now?
Empresa Distribuidora y Comercializadora Norte Sociedad Anónima (EDN) offers the better valuation at 5.2x trailing P/E (0.1x forward), making it the more compelling value choice. Analysts rate Edison International (EIX) a "Buy" — based on 36 analyst ratings — the highest consensus in this comparison. The "better buy" depends entirely on your goals: growth investors should weight revenue trajectory, value investors should weight P/E and PEG, and income investors should weight dividend yield and streak.
02Which has the better valuation — EIX or NGG or EXC or FE or EDN?
On trailing P/E, Empresa Distribuidora y Comercializadora Norte Sociedad Anónima (EDN) is the cheapest at 5.2x versus FirstEnergy Corp. at 29.1x. On forward P/E, Empresa Distribuidora y Comercializadora Norte Sociedad Anónima is actually cheaper at 0.1x. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Empresa Distribuidora y Comercializadora Norte Sociedad Anónima wins at 0.00x versus Exelon Corporation's 2.75x — a PEG below 1.0 traditionally signals the market is underpricing earnings growth.
03Which is the better long-term investment — EIX or NGG or EXC or FE or EDN?
Over the past 5 years, Empresa Distribuidora y Comercializadora Norte Sociedad Anónima (EDN) delivered a total return of +585.1%, compared to +63.5% for Edison International (EIX). A $10,000 investment in EDN five years ago would be worth approximately $69K today (assuming dividends reinvested). Over 10 years, the gap is even starker: EXC returned +172.6% versus EIX's +48.9%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.
04Which is safer — EIX or NGG or EXC or FE or EDN?
By beta (market sensitivity over 5 years), Exelon Corporation (EXC) is the lower-risk stock at -0.04β versus Empresa Distribuidora y Comercializadora Norte Sociedad Anónima's 1.67β — meaning EDN is approximately -4173% more volatile than EXC relative to the S&P 500. On balance sheet safety, Edison International (EIX) carries a lower debt/equity ratio of 20% versus 188% for FirstEnergy Corp. — giving it more financial flexibility in a downturn.
05Which has better profit margins — EIX or NGG or EXC or FE or EDN?
Edison International (EIX) is the more profitable company, earning 24.3% net margin versus 8.4% for FirstEnergy Corp. — meaning it keeps 24.3% of every revenue dollar as bottom-line profit. Operating margin tells a similar story: EIX leads at 36.7% versus 2.1% for EDN. At the gross margin level — before operating expenses — NGG leads at 77.4%, reflecting greater pricing power or product mix advantage. Stronger margins indicate durable pricing power, lower cost of revenue, or higher mix of software/services. They are one of the clearest signs of business quality.
06Is EIX or NGG or EXC or FE or EDN more undervalued right now?
The PEG ratio (forward P/E divided by expected earnings growth rate) is the most precise measure of undervaluation relative to growth potential. By this metric, Empresa Distribuidora y Comercializadora Norte Sociedad Anónima (EDN) is the more undervalued stock at a PEG of 0.00x versus Exelon Corporation's 2.75x. A PEG below 1.0 is traditionally considered the threshold for growth-adjusted undervaluation. On forward earnings alone, Empresa Distribuidora y Comercializadora Norte Sociedad Anónima (EDN) trades at 0.1x forward P/E versus 23.1x for National Grid plc — 23.1x cheaper on a one-year earnings basis. Analyst consensus price targets imply the most upside for EXC: 2.2% to $50.55.
07Which pays a better dividend — EIX or NGG or EXC or FE or EDN?
In this comparison, FE (3.4% yield), EXC (3.2% yield), NGG (2.2% yield), EIX (0.5% yield) pay a dividend. EDN does not pay a meaningful dividend and should not be held primarily for income.
08Is EIX or NGG or EXC or FE or EDN better for a retirement portfolio?
For long-horizon retirement investors, Exelon Corporation (EXC) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β -0.04), 3.2% yield, +172.6% 10Y return). Empresa Distribuidora y Comercializadora Norte Sociedad Anónima (EDN) carries a higher beta of 1.67 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (EXC: +172.6%, EDN: +52.2%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.
09What are the main differences between EIX and NGG and EXC and FE and EDN?
Both stocks operate in the Utilities sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both. In terms of investment character: EIX is a mid-cap deep-value stock; NGG is a mid-cap quality compounder stock; EXC is a mid-cap income-oriented stock; FE is a small-cap income-oriented stock; EDN is a small-cap deep-value stock. NGG, EXC, FE pay a dividend while EIX, EDN do not, making them suitable for different income and tax situations. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
