Edison International (EIX)

Investment Committee Summary

Investment Thesis

At $55.64 (13 October 2026) on about 9x forward earnings, Edison International trades at a wide discount to the regulated-utility peer median despite comparable rate-base growth. That discount is the wildfire and California-regulatory overhang, not weak underlying fundamentals. The engine agrees the discount is warranted but not that it should be deeper: the base path assumes mid-single-digit growth at an operating margin near 23% (reported GAAP, TTM to Jun 2026) and a below-peer multiple, and the twelve-month target of $72.36 sits above the current quote while the probability-weighted expected value of $68.92 sits closer to it. Triangulation lands at $67.54, leaving the shares trading cheap to that anchor (+21%), so the rating is BUY: near fair value with a thin margin of safety rather than mispriced. Optionality from Southern California datacenter load sits in the higher-growth paths but is not yet contracted rate base and should not be capitalised until it is. The single most damaging risk is a fresh wildfire-liability charge: against net debt of ~$42.5B funding a capex programme running near a fifth of revenue, an incremental multi-billion reserve would compress earnings and the multiple simultaneously, the structural mechanism that carries the target below the 52-week low.

The dashboard below is the whole argument on one page: spot ($55.64) against each valuation anchor, the scenario tree, technicals and the options-implied move.

Anti-Thesis (The Real Bear Case)

The highest-probability bear mechanism is the adverse rate-case and rate-shock de-rate, and its logic is concrete. Edison funds a rising capital programme against net debt of ~$42.5B. If the California commission sets the allowed return below the level the plan assumes, or disallows recovery of a slice of that capital, the rate-base earnings stream stops compounding at the authorised pace exactly as financing cost rises. Layer a new wildfire liability, net of insurance and the state fund, on top of that, and the equity absorbs a charge the balance sheet is thin to carry. Earnings and the multiple then compress together, and the structural path drives the target below the 52-week low. In that world the peer discount is not an anomaly waiting to close but a correct assessment of regulatory and liability risk, and the dividend is the first thing that has to give.

Key Debate

Gross Margin explains 61% of Monte Carlo outcome variance — the single variable that decides which side is right.

What the Market Is Pricing In

At the current price, the market pays 9.1× consensus forward EPS, and a peer median 21.2×.

Variant perception: the house view is above-consensus, and the thesis is primarily growth-driven.

Scenario Analysis

The scenario tree spans a structural 'Structural — Adverse Rate Cases / Rate-Shock De-Rate' downside ($37.80) to a 'Bull — Defensive Re-Rate' bull case ($108); the probability-weighted blend (PWEV $68.92) is +24% versus spot.

SBC charge: scenario targets are gross per-share prices; the PWEV is reduced by one year of stock-based-compensation dilution (1.5% of shares, on SBC ≈ 0% of revenue), trimming the gross PWEV of $69.95 to $68.92 (-1.5%). SBC is charged once, as dilution — never also deducted from FCF.

Scenario rationale — the driver path behind every target:

• Structural — Adverse Rate Cases / Rate-Shock De-Rate (20%, $37.80). Structural impairment — adverse rate cases / rate-shock de-rate: earnings AND the multiple compress together. Target sits below the 52-week low by construction.
• Recession / Rate Spike / Cost Overrun (17%, $59.20). Cyclical downturn — rate-base growth + allowed ROE + rate cases + interest rates + load growth (datacenters) weakens for 1–2 years before normalising.
• Base — Rate-Base Growth + Allowed ROE (35%, $72.30). Mid-cycle — normalised rate-base growth + allowed ROE + rate cases + interest rates + load growth (datacenters); disciplined capital allocation; steady returns.
• Growth — Datacenter Load / Clean-Energy Capex (20%, $91.70). Upside — datacenter load growth + clean-energy capex lifts earnings above mid-cycle; the multiple expands modestly.
• Bull — Defensive Re-Rate (8%, $108). Upside tail — sustained tight conditions or a structural re-rate on datacenter load growth + clean-energy capex.

Valuation Triangulation

Two weighted anchors — a scenario-weighted pwev and a monte carlo median (student-t + regime switching) — read them with their basis in mind. The Monte Carlo, the scenario PWEV, any DCF's exit-multiple terminal and any peer re-rate key off a market multiple, so they are not independent; only a DCF's explicit-period cash flows are multiple-free, and its terminal usually carries most of its value. The discipline is to read the spread, not to treat two numbers as two independent votes.

The house blend DECLARES five anchor weights — DCF 35%, scenario PWEV 25%, Monte Carlo 15%, sum-of-parts 15%, peer re-rate 10%. For this name DCF, sum-of-parts are not computed, so 50% of the declared weight is redistributed across the anchors that exist — which is why the weights above differ from the declared ones. The fair value is unaffected by this disclosure; the blend has always worked this way.

Peer EV/Revenue re-rate — 0% weight: it duplicates the peer-multiple information already carried by the Peer P/E anchor while ignoring margin mix; weighting both would double-count the peer view. Shown as a cross-check.

peer P/E re-rate excluded from the weighted blend — diverges >55% from the Monte-Carlo / scenario core. For a high-leverage equity the per-share DCF (enterprise value less large net debt) is hypersensitive to the terminal multiple; a peer re-rate across heterogeneous margins is apples-to-oranges. Shown above for reference; the blend leans on the multiple-discipline and scenario anchors.

Monte Carlo — the outcome distribution

10,000 paths, Student-t shocks (fat tails) with a regime-switching overlay. The median lands at $65.25 and 63% of paths finish above spot. The variance decomposition shows the gross margin is the dominant swing factor (61% of variance). The fundamental driver, not the multiple, sets the spread — a cleaner setup.

Peer benchmarking — relative value

Against its 4 peers in the same GICS sub-industry, re-rating to their median forward multiple (P/E 21.2x) implies $130. A premium is only justified by superior growth/margins; otherwise it is multiple risk. Excluded from the weighted blend — shown only as a market cross-check.

Across all anchors the spread is 86% of the median — wide (genuine disagreement — the blend carries low valuation confidence).

Peer Quality & Weighting

Quality-weighted forward P/E: 21.1× (simple median 21.2×). Direct peers count 100%, segment 50%, broad 25%.

Historical-range cross-check: 52-week range $51.10–$81.62, centre $64.60 (+16% vs spot); spot sits at the 15th percentile of the range. Low-weight mean-reversion cross-check, not a fundamental anchor.

Risk / Reward & Margin of Safety

Reward/risk = (triangulated FV ÷ price − 1) ÷ (1 − 'Structural — Adverse Rate Cases / Rate-Shock De-Rate' target ÷ price). 'Structural — Adverse Rate Cases / Rate-Shock De-Rate' ($37.80, probability 20%) is the lowest-target scenario in the tree, taken gross of SBC dilution. Bull case (Bull — Defensive Re-Rate): $108.

How it makes money.

† Model margin = gross margin − the opex ratio calibrated so the Monte Carlo median EPS meets the EPS target; it is not a reported operating margin.

Reported operating margin (GAAP): 36.7% for the fiscal year ended 2025-12-31; 23.2% TTM to 2026-06-30 (Alpha Vantage INCOME_STATEMENT).

Edge. Wide moat — The moat is a state-granted regulated electric monopoly (Southern California Edison) with a CPUC-set rate base and allowed ROE; the franchise is wide but California wildfire liability is a genuine moat-impairing overlay. Falsifiable: the AB1054 wildfire fund and cost-recovery mechanism are the load-bearing assumption — if a major wildfire is deemed imprudent and costs fall outside the fund, franchise value is impaired and the multiple should stay one-third below the ~19-21x utility median rather than converge.

Decision Rules (Machine-Checked)

Stance: Hold — 1 bullish / 1 bearish / 0 caution rules triggered of 6 evaluable (0 lacked data).

Machine-checked rules over disclosed inputs. The authored falsification triggers elsewhere in this report are analyst judgment and are NOT evaluated here. The stance is what the model's own rules read on this name; it does not modify the published research rating, and it is not personal financial advice.

Reasons the Thesis Could Fail (Falsifiable)

Pre-registered signals that would break the thesis — each polices a specific scenario boundary and is checked at every earnings update:

• SCE authorised return on equity (GRC / cost-of-capital outcome) < 10.0% (single event). (rationale withheld pending re-authoring — frozen figure or verdict)
• Core EPS growth guidance (multi-year target) < 5% CAGR (single event). (rationale withheld pending re-authoring — frozen figure or verdict)
• Incremental Eaton/wildfire-related charge or reserve build > $1.0bn (single event). A material new wildfire charge net of insurance and the state fund would pressure the balance sheet and validate the structural-impairment mechanism rather than the recoverable-cost view.
• FFO / debt (Moody's-basis) < 14% (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)
• Annual capital-programme spend vs plan > $8.5bn (2 consecutive prints). Capex sustained above the top of the schedule without matching authorised rate-base recovery would signal cost overruns eroding return-on-capital rather than accretive rate-base growth.

Fact / Inference / Speculation

• FACT: Spot $55.64; 52-week range $51.10–$81.62; engine rating BUY; house target $72.36 (+30%). (source: Alpha Vantage 2026-10-12, 13 October 2026)
• INFERENCE: Triangulated FV $67.54 (+21% vs spot · triangulated FV); the rating tracks the Monte-Carlo + scenario-PWEV core.
• SPECULATION: At current prices the embedded bet is that Gross Margin keeps surprising favourably — an operating call the next two prints will test.

Conviction Score

Research Conviction measures the strength and quality of the research setup — input coverage, financial quality, valuation support, process agreement. It is NOT the probability that the recommendation succeeds; the forecast track record section is the evidence on that.

58.5/100 (confidence band 44.0–72.9), 53rd percentile of 928 covered names (as of 2026-10-12). Weighted composite under config ros-1.21.0 — every component and its inputs below.

Missing inputs (macro tailwinds) are excluded and the remaining weights renormalised; the confidence band widens accordingly.

Score history: 58.6 → 58.8 → 58.9 → 58.7 → 70.1 → 58.7 → 58.3 → 58.6.

Probability-Weighted Return Profile

Horizon: 1 year — at this horizon CAGR equals total return by definition. Expected values are the probability-weighted sums over the full scenario set below.

The gross expected return is the probability-weighted scenario return (it reconciles to the gross PWEV); the diluted figure applies the SBC share-count charge and matches the published PWEV-based target.

Expected Alpha

Expected return minus the return this name is REQUIRED to deliver for its risk (1-year horizon). Constants are pre-registered (preregistered-static (amendment #2, 2026-07-29); not fitted to MCH outcomes).

A negative expected alpha does not change the rating — it says the expected return does not clear the risk-adjusted hurdle at today's price. Rating mechanics are unchanged by this section.

Probability Cross-Checks

Not authoritative. The scenario probabilities in this report are AUTHORED — a judgement about how the world might go, not a measurement. Nothing below modifies them, the target, the rating or any position size. These checks ask only whether anything outside our own model agrees with us; where it does not, that is information for the reader, not a correction we have quietly applied.

Authored set: 5 scenarios, probabilities summing to 1.0, mean target $69.95.

Factor Exposures

Cross-sectional percentiles over 928 covered names (style scores sector-demeaned; thematic = return-beta to the theme's proxy ETF). 50 = estate median.

Market interaction: correlation vs SPY +0.21, vs QQQ +0.11 (trailing ~1y daily returns).

Rating Bridge

Rating = BUY because:

• Probability-weighted scenario value implies +24% vs spot
• Monte Carlo median implies +17% vs spot
• Bear case (Structural — Adverse Rate Cases / Rate-Shock De-Rate) downside is -32% vs spot
• Net: reward/risk of 0.7× supports a Buy — note this is below 1.0×, i.e. the modelled downside exceeds the modelled upside despite the Buy rating.
