Sempra stock plunged on Tuesday after the energy infrastructure company reported weaker-than-expected earnings for the fourth quarter and reduced its full-year guidance.

Shares fell 22% to $67.64, putting them on pace for the largest same-day percentage decrease since Feb. 5, 1992, according to Dow Jones Market Data. Sempra was the worst-performing stock in the S&P 500 on Tuesday.

The company reported fourth-quarter earnings of $1.50 a share, missing analysts' calls for $1.60. Revenue of $3.8 billion also fell sharply below the FactSet consensus estimate of $4.9 billion. But a weak outlook was weighing the most on the shares Tuesday, as Sempra said it was revising its full-year earnings guidance range due to "regulatory matters and the backdrop of a higher-cost environment."

The new range of $4.30 to $4.70 a share is down from an earlier range of $4.90 to $5.25 and below the $5.16 a share analysts expected, according to FactSet. The company also issued its 2026 outlook, calling for earnings between $4.80 and $5.30 a share. Wall Street was expecting $5.56 a share.
