What happened this week

State lawmakers introduced a bill on Saturday to remake California's wildfire liability framework without the utility protections Governor Gavin Newsom had pursued. The omission sent the state's utility stocks sharply lower. PG&E Corp. dropped as much as 21% intraday, its worst such move since 2020. Edison International plunged 24%, the biggest single-day slide since 2018. Sempra declined up to 5.6%, its sharpest intraday fall since April 2025. The companies had rallied earlier this year on expectations for favorable legislation and anticipated power demand growth from data centers.

For it to take effect, the bill still needs approval from both the assembly and the senate, followed by the governor's signature. Newsom's office did not respond to a request for comment.

Why the bill matters to markets

Investors had counted on liability relief that didn't materialize in the draft, triggering downgrades. BMO Capital Markets' James Thalacker cut PG&E to market perform from outperform, writing that the proposal does not ensure the state wildfire fund's financial strength or protect utilities from bankruptcy tied to fire risk. He added that investor caution around fire liabilities could make capital raising tougher for PG&E versus peers. Wells Fargo's Shahriar Pourreza cautioned that, without legal protections, utilities remain exposed to potentially billions in losses from severe, utility-sparked fires; he cut PG&E's rating to equal weight from overweight, while maintaining underweight on Edison. Mizuho's Anthony Crowdell moved PG&E, Edison and Sempra to neutral from outperform and reduced price targets, and he expects utilities to seek friendlier legislation next year - an "uphill climb" given that a different state administration will be in place following the November election.

The politics and the debate over costs

Before the bill appeared, Newsom floated a plan - supported by utilities - that would have prevented insurers from seeking reimbursement from utilities that ignite fires. He argued those reimbursements represent the largest pool of post-fire money, leaving less for survivors. Amid a warming climate, he has made overhauling liability and reinforcing mitigation and recovery central aims of his concluding legislative session.

Insurers, ratepayer advocates and fire victims countered that his idea would shift costs and could lift premiums by up to 20%, citing an analysis by the American Property Casualty Insurance Association. They also argued that allowing insurers to continue recovering payments from utilities would not drain California's wildfire fund and that the plan favored utility investors over survivors. "This outcome keeps costs with the parties responsible for wildfires and helps protect the progress California is making in stabilizing its insurance market," the insurance association said after lawmakers filed the bill. Opponents also told lawmakers the fund's solvency was not in jeopardy, saying the top-end damage estimate for the Eaton Fire remains below the wildfire fund's original capacity. As Every Fire Survivors Network wrote in an August letter, "Bankruptcy is hardly around the corner. So show us the emergency."

What utilities said and what's next

PG&E warned Sunday that the bill "does not adequately address the financing risks created by California's current wildfire liability framework," adding it falls short of delivering the long-term durability needed to attract "affordable investment to support a safer, more reliable energy system and help keep costs down for customers." PG&E's vulnerability is acute: it filed for Chapter 11 in 2019 after billions in wildfire liabilities, and, according to BMO's Thalacker, management has signaled that without meaningful improvements to the wildfire fund framework that both preserve the fund and protect investor-owned utilities against another bankruptcy, the company would contemplate alternative capital allocation strategies. Edison International's Southern California utility was "disappointed that the state couldn't develop a comprehensive wildfire reform," spokesperson Kathleen Dunleavy said.

For investors, the takeaway is that California policy remains a powerful driver of utility valuations. Watch the bill's progress in Sacramento and further analyst revisions, as the companies are likely to renew their push for liability relief next year.
