Sempra’s share price has climbed 65.1% over the past five years. With the stock recently closing at US$92.25 and broader checks flagging it as expensive, investors are weighing strong past returns against signals that it may no longer be a clear bargain.

• A 65.1% gain over five years highlights that Sempra has already delivered solid long term returns, which can raise the bar for what counts as attractively priced today.
• Progress at Sempra Infrastructure, including the first LNG cargo from the ECA LNG project and planned simplification of the business toward regulated utilities, can support higher earnings expectations. At the same time, execution risks around large projects and leadership changes may limit how much investors are willing to pay.
• Sempra passes 0 of 6 valuation checks. This indicates the stock leans expensive rather than showing up as a clear bargain on Simply Wall St’s broader screening of price versus fundamentals, see 0/6.

The issue now is whether Sempra’s current price already reflects these LNG milestones and planned portfolio shifts, or if there is still room for further upside without stretching valuation too far.

Is Sempra Getting Expensive on Earnings?

The P/E ratio is a common way to look at Sempra because it is designed to be an earnings driven utility company. Sempra currently trades on a P/E of about 31.3x, compared with an integrated utilities industry average of roughly 19.3x and a peer group average near 20.1x. This puts the stock at a clear premium to both sets of benchmarks.

The fair P/E multiple implied by Simply Wall St’s model is 27.3x, which is lower than where Sempra trades today and suggests investors are already paying up relative to what the company’s profile might support. Despite the recent LNG progress and planned shift toward a more regulated earnings mix, the current valuation still sits above this tailored fair ratio.

On this P/E yardstick, Sempra stock screens as overvalued compared with both its fair ratio and the broader utilities sector.

The Bottom Line

For investors looking at Sempra today, the key takeaway is that the stock currently screens as overvalued on earnings-based market multiples, with a low value score and little support from broader valuation checks. That does not rule out further upside. However, it does mean the market already prices in a lot of confidence around LNG execution, the shift toward regulated utilities and leadership transition. The crux of the debate from here is whether those expectations prove justified enough to support the premium P/E, or whether any hiccups on projects or earnings mix prompt investors to rethink how much they are willing to pay for Sempra.
