Edison Falls 24% as California Declines to Cap Wildfire Damages

Monday was the last day of California's legislative session; the bill that passed in Sacramento lacked the three provisions the market wanted.

No fire started, no court ruled, no company reported earnings. Edison International and PG&E still lost $13.2 billion in combined market value.

Edison fell 23.9% to $53.41; in the 2001 California energy crisis it lost more than 35% in one session.

PG&E fell 18.4% to $13.55; Sempra fell 2%, XLU just 1%. Not a sector story, a state-statute story.

California's Strict Liability Rule

State courts treat damage from a utility's equipment under the doctrine of inverse condemnation.

That rule pushed PG&E into bankruptcy after the 2017-2018 fires.

In 2019 the state answered with AB 1054: strict liability stayed, with a buffer behind it. The three large investor-owned utilities put in $7.5 billion up front plus $3 billion over ten years, and a bill charge was to raise $10.5 billion more; capacity was cited as $21 billion.

It also capped shareholder repayments to the fund at 20% of the three-year T&D equity rate base — about $2.2 billion for Southern California Edison, $2.1 billion for PG&E, $692 million for SDG&E.

How the Eaton Fire Broke the Balance

The Eaton Canyon fire of January 7, 2025 burned roughly 14,100 acres, destroyed 9,418 structures, damaged 1,071 more and killed 19 people.

UCLA puts total cost between $24 billion and $45 billion, insured losses alone at up to $15.2 billion; state documents warn the claims may exhaust the fund if Edison is found liable.

Edison has booked about $1 billion; its direct payment program has 2,405 claims and 593 offers totaling $183 million, with up to 18,000 properties eligible. Jefferies models total liability at $13.5 billion: 2.5 claims per property at $300,000.

The Mechanism: A Cap Tethered to a Fund

The 20% cap is not free-standing; it caps what the utility repays the fund. Drain the fund and there is nothing to repay and nothing to pay claimants with, and strict liability lands on the balance sheet.

Mizuho's reasoning in cutting Edison: nothing in the bill severs the link between the fund's solvency and the cap.

"SB 492 provides no new funding into the wildfire fund."

That is what the market priced on Monday: no mechanism to add money, no repeal of the 2028 sunset on the continuation fund, no $6 billion per-incident cap.

Edison's entire market capitalization at Monday's close was $20.55 billion — less than the stated capacity of the fund behind it.

The Clause the Insurers Won

The most contested item was the elimination of subrogation, under which an insurer pays its policyholder and then pursues the utility. Strike it and up to $15.2 billion of insured Eaton losses moves to the insurance industry's ledger.

The industry called it a bailout; it did not make it into law.

Consumer Watchdog, which represents fire survivors, called the text a win: no smoke-damage perimeter restriction, subrogation preserved.

"does not cap economic or noneconomic damages"

Sempra's 2% is no accident: much of its revenue comes from Texas and Mexico.

Friday's decline shows the news was partly priced; Monday told the market the other two clauses were not coming.

The Second Channel: Cost of Capital

A utility's profit is the spread between the allowed return on its regulated asset base and the cost of financing it; borrowing cost goes straight to earnings.

PG&E's credit rating sits one notch below investment grade at S&P. Edison's five-year capital plan runs $38 billion to $41 billion.

On that plan, 100 basis points of extra financing cost is roughly $400 million a year. Against 2026 guidance of $5.90 to $6.20 a share and roughly 385 million shares, net income is about $2.3 billion — a sixth of it.

PG&E made the same point:

"does not adequately address the financing risks"

Mizuho cut Edison to Neutral, $86 to $70, and Sempra to Neutral, $104 to $84. BMO cut PG&E to Market Perform, $28 to $21, raising the wildfire drag from $6 to $10 a share. Wells Fargo took PG&E to Equal Weight.

The other side: the fund still stands, Eaton claims are unsettled, the fast-pay track shortens the litigation tail, Edison has booked only $1 billion, and the stock trades at 8.8 times midpoint guidance.

The S&P 500 tracker fell 0.27%, the Dow tracker 0.65%, the Nasdaq 100 tracker rose 0.07%; Hormuz military activity pushed Brent up 3.4% to $91.10.

What Is Left

No cash changed hands on Monday; what changed was uncertainty about whose ledger a future loss lands on.

A company is priced partly on its insulation against that tail; remove it and the same assets price lower. That is the valuation side.

Three things to watch: the rating agencies' September decisions, the Catastrophe Response Council's assessment of the fund, and whether a fresh attempt comes in 2027 — Mizuho sees that as difficult with a new administration in January.

California's electric utilities have long counted as defensive stocks paying a steady dividend. Monday showed which assumption that rested on.
