Sempra Stock Slides After Mizuho Downgrade on California Wildfire Reform Failure

Sempra Energy (SRE) shares declined 3.6% in pre-open trading after analysts downgraded the stock in response to California lawmakers failing to enact key wildfire liability reforms sought by utility investors.

Analyst Actions and Price Target Cuts

The primary catalyst for the sell-off was a downgrade from Mizuho, which lowered its rating on Sempra to Neutral from a previous Outperform. The investment firm also significantly cut its price target on the stock to $84 from $104, according to a report from Investing.com.

Adding to the negative sentiment, Ladenburg Thalmann also trimmed its price target on Sempra to $98 from $102.50, although it maintained its Buy rating on the shares. The stock's decline pushed it toward its 52-week low of $78.97.

Wildfire Legislation Disappoints Investors

The analyst revisions followed the passage of California Senate Bill 492 on August 29. Investors had anticipated the legislation would provide financial relief for utilities, but the final bill disappointed those expectations. Specifically, the bill omitted two key provisions:

Ad

• A replenishment mechanism for the state's wildfire insurance fund.
• Changes to the linkage between the fund's solvency and utility liability caps.

This outcome leaves Sempra's California subsidiaries, San Diego Gas & Electric (SDG&E) and SoCalGas, with significant ongoing financial exposure to liabilities from future wildfires, creating a more uncertain regulatory outlook.

Sector-Wide Impact

The legislative disappointment weighed on the entire California utility sector. Shares of peer PG&E (PCG) also dropped sharply on the news. The broader Utilities Select Sector SPDR Fund (XLU) also declined, reflecting widespread concern among investors.

A generally weaker tone in the broader market, with the S&P 500, Dow Jones, and Nasdaq all trading lower, further amplified the selling pressure on Sempra and other utility stocks sensitive to regulatory risk.
