Joby Aviation (JOBY) Stock Trades At A Premium Despite Weaker Sentiment

Simply Wall St·07/23/2026 08:25:01
Listen to the news

Joby Aviation stock has given up much of its earlier enthusiasm, with a steep share price decline over the past year sitting alongside valuation checks that currently flag the company as expensive rather than a bargain.

  • Over the past 12 months, Joby Aviation shares are down 56.6%, which means anyone buying a year ago is sitting on a large loss even after the recent pullback.
  • On the one hand, a sizeable cash balance may support Joby Aviation as it works toward eVTOL certification. On the other hand, regulatory delays and a patent dispute with Archer add uncertainty that can weigh heavily on what investors are willing to pay today.
  • Joby Aviation passes 0 of 6 valuation checks on Simply Wall St, which signals that, on the broader measures, the stock does not currently screen as a clear bargain for investors looking at price versus fundamentals (0/6 valuation score).

The issue now is whether Joby Aviation's weaker share price has created an entry point or if the stock still asks too much for the risks in front of it.

Find out why Joby Aviation's -56.6% return over the last year is lagging behind its peers.

Is Joby Aviation Getting Expensive on Book Value?

P/B is often a useful check for pre-revenue companies like Joby Aviation, because it anchors the share price to the net assets on the balance sheet rather than earnings that are not yet in place.

Joby Aviation currently trades on a P/B of 3.8x, compared with an airline industry average of about 1.9x and a peer level of roughly 1.8x. That is a sizeable premium for each dollar of book value, even though the business is still working through regulatory approvals and continues to report large cash outflows. Despite the recent pullback after news of certification delays and the patent dispute, the stock still prices in materially more optimism about future use of that asset base than is reflected in the typical airline or peer company.

On this P/B yardstick, Joby Aviation stock screens as overvalued relative to both its industry and peer benchmarks.

The Bottom Line

Joby Aviation still screens as overvalued on traditional market multiples, with the current P/B premium asking investors to pay up for a business that is pre-revenue and working through certification and legal risks. The low value score underlines how few standard checks currently support the case that the stock is cheap. From here, the key question is whether Joby Aviation can turn its cash, partnerships and manufacturing footprint into commercial scale fast enough to justify that premium, or whether the market is already paying too much for a story that will take time and execution to prove out.
