Is Joby Stock Priced For The Wrong Business?

Joby Aviation (JOBY) stock has fallen 49.2% over the trailing twelve months to about $6.84, about 65% below its 52-week high. The shares change hands at 57.0 times sales, against 3.2 for the S&P 500. That multiple is accurate. It also measures a passenger brokerage business that represents a transitional step rather than the long-term eVTOL manufacturing thesis driving the stock’s valuation.

What Is Joby Selling You Right Now?

Blade is where the revenue comes from. The passenger flight business supplied most of the $39 million Joby booked in Q2 2026. Seats sold were up over 50% from a year earlier, Blade’s best second quarter on record by that measure, and route expansions drove more than 40% year-on-year growth in Hamptons revenue.

Set that against a market value of about $6.6 billion and the sales multiple explains itself. Joby raised its full-year 2026 revenue guidance to $115 million to $125 million on Blade’s strength; yet despite an initial post-earnings pop, the stock has trended lower as investors weigh long-term cash burn against commercial delivery milestones.

So Why Did Joby Fall On Good News?

Because the price is not about the revenue line. Joby has 5 electric air taxis in the air, including its first FAA-conforming aircraft, and 12 more in various stages of production. Management is targeting at least 2 aircraft off the line over the back half of 2026, and says building conforming aircraft is a step change in complexity.

The next test is Texas. Joby intends to fly its first routes across the Dallas-Fort Worth area in September 2026 under the White House-backed eVTOL Integration Pilot Program, or eIPP, starting with pilots on board before nonpaying and then paying passengers. Ask what that program is worth and there is no dollar figure yet—the CFO called it premature to guide on eIPP revenue, though he noted the program’s markets alone could absorb Joby’s entire aircraft production for quite some time.”

Can You Afford To Wait For The Aircraft?

You fund the wait. Joby’s operating margin is deeply negative at -759.2%, against 18.6% for the S&P 500, on a trailing-twelve-month operating loss of about $0.9 billion. Management guides $385 million to $415 million of cash use in the second half of 2026, and Joby has agreed to buy Resonant Sciences for about $500 million.

The balance sheet is the honest counter. Cash and equivalents are 82.3% of total assets against 6.6% for the market, and the company ended Q2 2026 with about $2.3 billion in cash, cash equivalents and short-term investments. Joby does not have to hurry, though a potential $750 million share sale is linked to the Resonant deal—a dilution headwind offset by bringing in a defense business generating more than $100 million in revenue.

A downturn has already shown what that costs. JOBY fell 51% in the 2022 inflation shock while the S&P 500 fell 24%, and from its low it took about 16 months to reclaim its pre-crisis high.

So what are you buying? A sales multiple built on Blade’s seats, a cash pile of about $2.3 billion, and a certification schedule that has reached the fifth and final stage of FAA approval—targeting its first passengers this year—even if management will not yet hang a dollar figure on the timing. That is a genuinely hard call, and the market has spent a year marking it down while the revenue guide went up. Watch the aircraft leaving the line over the back half of 2026 rather than the guidance range.
