Sempra (SRE), What Is Behind The Fresh Attention?

Listen to the news

Sempra (SRE) has reignited investor discussion after signing a 20-year LNG supply agreement with Petrobras related to its Port Arthur Phase 2 project, which involves approximately US$12 billion of planned capital spending.

Recent trading tells a mixed story. Sempra’s 1-day share price return of 0.59% contrasts with a 30-day share price decline of 5.74% and a 90-day slide of 9.38%, even as its 5-year total shareholder return of 47.73% keeps the long-term record in focus.

After a solid 5 year record and a fresh LNG deal on the table, Sempra now sits in a very different spot than it did a year ago. Is today’s pullback enough of an entry, or is patience worth more?

Most Popular Narrative: 20.6% Undervalued

On the most followed view, Sempra’s fair value of $103.50 sits well above the recent $82.18 close. This puts the current pullback against a backdrop of fairly modest modeled growth and a relatively low discount rate of 7.11%.

Grid modernization, wildfire hardening, and the integration of renewables and storage in California and Texas will expand the company's regulated asset base and enable approved rate increases, supporting both margins and top-line growth as electrification and decarbonization accelerate.

Result: Fair Value of $103.50 (UNDERVALUED)

Still, the whole Sempra story can change quickly if regulators squeeze allowed returns in California, or if LNG projects face demand or policy setbacks.
