Is Joby Aviation (JOBY) Above Fair Value As Sales Stay Thin?

Simply Wall St · 1d ago

Joby Aviation has seen its stock slide sharply over the past year, even as the business moves closer to launching electric air taxi services. With the share price now reflecting a very different market mood, the key issue for investors is how well that price lines up with the company’s sales.

  • The stock has fallen 66.5% over the past 12 months, which puts fresh focus on whether the current valuation can still be explained by Joby Aviation’s revenue base.
  • Progress toward FAA certification and preparations for commercial flights, backed by Toyota’s investment and manufacturing support, may influence how quickly future sales can ramp and how much funding the business might still require.
  • Your read on Joby Aviation is one view; the desks covering it have another. See what analysts think Joby Aviation's shares could be worth.

The issue now is whether Joby Aviation’s current share price is justified by its sales when judged against the Fair Ratio benchmark.

Has Joby Aviation Run Too Far on Sales?

The price-to-sales (P/S) ratio fits Joby Aviation better than earnings-based metrics because the business is still loss making and investors are effectively paying for future revenue potential rather than current profits.

On this yardstick, the stock trades on a P/S of 48.9x, far above the Airlines industry average of 0.5x and a peer group around 0.7x. That is a very rich top line multiple for any transport business, even one building a new category, and it means each dollar of Joby Aviation sales is priced at a heavy premium to more mature operators. The Fair Ratio model, which adjusts for factors such as growth profile, margins, size and risk, flags the current P/S as higher than the level it would expect and effectively treats the gap as a warning signal rather than a precise target.

Because Joby Aviation is progressing toward FAA certification and first commercial flights, and has visible backing from Toyota, faith in the story already appears heavily embedded in the valuation multiple. Despite that support and the Dallas Fort Worth launch plans, the current P/S still screens as expensive on this framework compared with what the Fair Ratio would imply for the stock.
