NRG Energy stock has more than tripled over the past three years, yet the current checks suggest it is no longer a clear bargain and now looks closer to fairly priced on market multiples.

• NRG Energy has delivered a 214.2% return over three years, which puts extra focus on whether today's price still offers an attractive entry point.

• Growth tied to the LS Power assets and the Vivint Smart Home segment can support earnings expectations, while execution risks around the large Texas data center generation project may weigh on how much investors are willing to pay for the stock.

• The company scores just 2 out of 6 on our valuation checks . This leans more toward expensive than clearly undervalued on the broader set of metrics.

For investors, the debate is whether NRG Energy's recent pullback has reset the price enough after such a strong three year run, or if the stock is still pricing in much of the good news already.

Find out why NRG Energy's -21.8% return over the last year is lagging behind its peers.

Does NRG Energy Look Fairly Valued on Earnings?

The P/E multiple is a useful way to look at NRG Energy because earnings remain a key focus for this type of utility and energy services business. NRG Energy currently trades on a P/E of about 30.0x, which is higher than the electric utilities industry average of 20.3x and also above the peer group average of 18.0x.

The company's model based fair P/E ratio is 29.5x, which is very close to where NRG Energy trades today. Despite the recent positive attention around LS Power, Vivint Smart Home and the Texas data center project, the current valuation already aligns closely with what this framework suggests investors might pay given its profile. On this P/E view the stock does not screen as a clear bargain or as especially expensive relative to its own fundamentals.

Overall, NRG Energy looks priced roughly in line with what the tailored P/E multiple suggests is fair right now.
