Frontier Group Holdings (ULCC) is back in focus after the company reported first quarter results that exceeded analyst expectations on both earnings per share and revenue, along with stronger guidance for the upcoming quarter.

The earnings beat and stronger guidance have arrived alongside a sharp improvement in momentum, with a 90 day share price return of 65.47% and a 1 year total shareholder return of 50.13%, while the 3 and 5 year total shareholder returns remain well below break even.

So with the stock around US$5.99, recent gains above 50% over the past year and a market value near US$1.4b, are you looking at an undervalued airline turnaround, or is the market already pricing in future growth?

Most Popular Narrative: 22.5% Overvalued

Frontier Group Holdings' most followed narrative pegs fair value at $4.89 per share, compared with the latest close of $5.99, setting up a valuation story driven by growth, margins and future earnings multiples.

The expansion of premium product offerings (e.g., first-class seating, UpFront Plus), increased loyalty cardholder engagement, and enhanced ancillary service monetization are driving higher non-fare revenue per passenger, supporting both top-line growth and margin expansion over the medium term.

Want to see what kind of revenue curve and margin reset would need to sit behind that fair value? The narrative leans on faster top line growth, a swing into profitability and a future earnings multiple that has to be justified by those targets. The full breakdown shows how those pieces fit together.

Result: Fair Value of $4.89 (OVERVALUED)

However, there is still the risk that ongoing oversupply in U.S. domestic routes and rising non fuel costs could squeeze margins and challenge the current fair value narrative.

Another Lens On Valuation

The fair value narrative points to Frontier Group Holdings trading above the US$4.89 estimate. However, its P/S ratio of 0.4x sits below both peer levels at 0.5x and the global airlines average at 0.6x, and in line with a fair ratio of 0.4x. This raises the question of whether sentiment is already too cautious.
