Barclays Cuts Joby Aviation, Sending Stock Down 5% Friday

NEW YORK, October 10 —

Joby Aviation, Inc. (JOBY) dropped roughly 5% Friday after Barclays issued a downgrade, leaving the stock at $5.44 with trailing EPS of $-0.97.

$436mn Burned, $116mn Earned: That Gap Is What Friday Was About

JOBY generated $116mn in TTM revenue while burning $436mn in FCF over the same period. With trailing EPS at $-0.97 and a forward P/E of -8.4x, the stock has no earnings anchor today; its value rests entirely on terminal assumptions about commercial air taxi revenue that does not yet exist.

That makes the Barclays downgrade a call on timing, not viability. The company burns more cash than it earns, but the model only closes once FAA certification unlocks commercial operations. The question the note implicitly raises is how many dilutive capital raises stand between today's price and that date.

257,000% Revenue Growth Is This Story's Most Misleading Number

JOBY reported 257,493% YoY revenue growth to that level TTM. That number is real, but it reflects a near-zero prior-year base, not a commercial inflection. The company has not launched service; FAA certification remains the pending gate. Revenue at this stage tells you the prior year was negligible, not that the business model is proving out.

The gap-down visible in the chart is the market pricing the FCF reality, not the topline growth story. Barclays apparently reached the same conclusion.

Bears Were Already In Before Barclays Printed the Note

With 18.6% of JOBY's float already short, the downgrade was not a revelation for bears, it was a catalyst. The Friday move read as existing shorts holding position and longs stepping aside rather than a fresh wave of aggressive shorting. A decline of that size, not a flash crash, suggests the market absorbed the note without a structural repositioning.

Trefis published a contrarian take questioning whether the drop overshot. That view deserves tracking. Sell-side downgrades on pre-commercial aerospace names have a history of overweighting near-term burn while underweighting certification timeline optionality. That is not a refutation of Barclays, but it does define the live disagreement in this stock.

One FAA Milestone Would Make the Barclays Downgrade Look Early

The FAA's next official communication on JOBY's type certification progress is the one data point that genuinely resets the trade. A step forward compresses the loss runway, changes terminal value assumptions, and gives that revenue line a commercial context it currently lacks. The Barclays note would then look like a timing error, not a thesis.

If certification slips, the $436mn annual FCF burn becomes the dominant frame and the downgrade ages well. Run your own certification timing scenarios through the DCF calculator to map what the stock is worth under each outcome.
