Joby Aviation (JOBY) drew fresh attention after finalizing a multi year commercial agreement with Virgin Atlantic, making the airline its exclusive UK partner and integrating Joby’s electric air taxi service at London Heathrow and Manchester.

Despite the Virgin Atlantic agreement and recent showings at Farnborough and other events, Joby Aviation’s 1 year total shareholder return is down 56.94%, while the year to date share price return has fallen 47.49%. This points to fading momentum despite a small 7 day share price rebound.

For Joby Aviation, the Virgin Atlantic deal and recent share price slide pull in opposite directions, so the real test now is how much of that future promise is already in the price and what patience might be worth.

Most Popular Narrative: 32.2% Undervalued

Compared with Joby Aviation’s last close at $7.54, the most followed fair value estimate of $11.12 suggests a sizeable gap that hinges on ambitious growth and margin assumptions.

The business model now spans manufacturing, a vertically integrated air taxi network, defense variants, autonomy software and Blade’s existing helicopter routes. This breadth of initiatives could stretch management focus, introduce integration risks and keep operating expenses elevated, which may weigh on future net margins and delay any path to sustained earnings.

Want to see what kind of revenue ramp and margin shift would need to sit behind that $11.12 figure? The narrative leans on rapid scaling, improving profitability and a future earnings multiple more often associated with mature high growth leaders, not loss making aviation stocks.

Result: Fair Value of $11.12 (UNDERVALUED)

However, if Joby Aviation’s FAA certification schedule slips, or early air taxi demand and pricing fall short, the current fair value story could be challenged.

Another View: What Joby Aviation’s P/B Says About the Story

The fair value narrative around Joby Aviation leans on future earnings and growth. Today the stock trades on a P/B of 3.8x versus 1.9x for the global airlines industry and 1.7x for peers. That premium suggests valuation risk if the air taxi thesis takes longer than hoped to play out.

For investors comparing these signals, the key question is whether Joby Aviation’s current premium is a cushion of confidence or a thin layer of optimism that could compress quickly if expectations change, and what that means for position sizing and holding periods.
