Joby's Q2 loss more than doubled — Blade revenue isn't the eVTOL story

Joby Aviation reported a stronger quarter — or so the headlines say. Revenue beat estimates. Blade is generating real passenger income. The FAA certification machine keeps turning. The stock jumped 5.5% on the news.

The net loss more than doubled, from $110 million in Q1 to a Q2 net loss of $245 million. The market's reaction is backward.

The variable swap: Blade is a bridge, not the destination

Joby's Q2 revenue was $38.6 million, well ahead of the $31 million estimate. The eVTOL aircraft that the entire thesis rests on generated virtually zero revenue.

Blade matters as infrastructure. It gives Joby existing heliports in Manhattan, routes that are already operational, and a customer base to transition when electric aircraft arrive. It's a smart bridge play. But it's not proof the eVTOL business works. It's helicopter revenue dressed up as air taxi revenue.

The loss widened, not shrank

Q2 GAAP net loss was $245 million, up from $110 million in Q1. Operating expenses climbed to $300 million from $258 million. Gross profit improved to $10.3 million — that's a real positive — but the expense base is growing faster than the top line.

The Q2 loss was roughly double Q1 because of the full-quarter drag of integrating Blade, scaling the Ohio manufacturing footprint, and pushing through the final stage of FAA testing. Some of that is one-time integration cost. Some of it is the reality of building an aircraft certification program from scratch. But the operating expense trajectory — up 16% quarter-over-quarter while revenue grew 60% — is the number that matters.

The valuation math

Joby trades at roughly $8.1 billion of market cap, or $6.3 billion of enterprise value after accounting for cash. The company raised its full-year 2026 revenue guidance to $115 million to $125 million, midpoint $120 million. That enterprise value implies 53 times forward sales.

Aircraft OEMs with actual production, actual revenue, and actual earnings — Lockheed Martin trades at 1.7 times sales. GE Aerospace trades at 7.7 times. Joby is trading at 53 times revenue that's almost entirely helicopter operations, with the real product still waiting for regulatory approval.

The enterprise-value-to-forward-sales multiple doesn't price in success. It prices in a flawless certification timeline, immediate commercial uptake, rapid fleet deployment, and a competitive moat that hasn't been tested. The margin for error at this multiple is thin.

Where the bull case still has legs

FAA Stage 4 is complete. Joby's first FAA-conforming aircraft (N547JX) is in flight testing. Stage 5 — the final gate — is where the company reports its "strongest quarterly progress yet."

What would have to go right

The stock needs three things to justify its current price:

Stage 5 closes without major safety findings. The FAA doesn't work on schedules, and even Joby's "strongest progress yet" doesn't guarantee a clean path through the last gate. A significant finding that resets the testing clock is the single biggest execution risk.

eVTOL revenue materializes in 2027. The real revenue story doesn't start until the aircraft are certified, an air carrier certificate is issued, and vertiports are operational. FY2027 is the earliest Joby can realistically generate meaningful eVTOL revenue. Until then, the business remains a cash-consuming development program.

Insider selling stops. Management conviction is a binary signal at this stage. Selling is normal for employees with vesting schedules, but sustained selling at these levels — especially by the CEO — undermines the case that insiders believe the current valuation reflects the future business.

The bottom line

Joby is the most advanced player in the U.S. eVTOL race. The Blade acquisition was a smart structural move. The FAA certification path, while not guaranteed, is the furthest along of any American competitor. Archer Aviation, Joby's closest rival, trades at half Joby's market cap despite a similar pre-revenue status.

But "most advanced" doesn't automatically mean "undervalued." At 53 times forward sales with a $245 million quarterly loss and widening operating expenses, the stock doesn't trade at a discount. It trades at a premium that assumes execution perfection.

AInvest's aggregate signal labels Joby a Hold — sitting between the bulls who see the first air taxi platform and the bears who see an expensive development program with no revenue from its core product. The signal reflects the tension, not a resolution.

The stock likely needs to find a bottom before it becomes attractive on a valuation basis. A catalyst-driven re-rate is possible if Stage 5 closes on time and eVTOL revenue starts flowing in 2027. But the break condition is clear: if Stage 5 drags, if losses continue to outpace the guidance envelope, or if insider selling persists through the certification finish line, the premium has no anchor.
