Joby Aviation stock slips premarket as Uber Air tie-up and FAA certification timeline draw scrutiny

New York, Feb 27, 2026, 08:03 EST — Premarket

  • Joby Aviation slipped 1.7% before the bell, giving up some gains after its 4.2% jump last session.
  • Air-taxi maker tapped Dubai for its initial passenger rollout this year and detailed new progress with the FAA.
  • The quarter saw the company pull in $30.8 million in revenue, yet it ultimately posted a net loss of $121.5 million.

Joby Aviation slipped 1.7% to $10.06 before Friday’s bell, giving back some ground after a 4.2% jump the day before. Traders have been quick to react to new certification updates and talk of a possible Uber partnership.

Electric air taxi startups are racing the clock. Money’s burning as they bide their time on regulatory nods, with timelines slipping. For Joby, the next phase is critical—turning all those test flights and paperwork into a real, running commercial service is the new benchmark.

Joby says it’s on track to fly its first passengers in Dubai before year-end, following what the company called a record 18-point jump in stage four of the FAA type certification process. The firm added that its first FAA-conforming aircraft, which is required for “Type Inspection Authorization”—the milestone that gets FAA pilots actually flying the aircraft for certification—should be in the air shortly.

Joby CEO and founder JoeBen Bevirt described 2026 as a “key inflection point” for the company. He said the focus now shifts to aircraft production figures and identifying where these vehicles will be put into service.

Joby posted fourth-quarter revenue of $30.8 million, the company said in its latest shareholder letter. Net loss for the period reached $121.5 million. Operating expenses totaled $237.6 million. Joby also pointed investors to a run of upcoming conferences with Raymond James, Morgan Stanley, Cantor Fitzgerald and J.P. Morgan.

Uber’s latest move: “Uber Air powered by Joby” will give users the option to schedule flights right inside the Uber app. Ground travel? That still runs through Uber Black. “The goal is a simple and familiar, one-tap experience,” said Chief Product Officer Sachin Kansal. Uber Investor Relations

Eric Allison, Joby’s Chief Product Officer, says the company aims to build “a new layer of urban transportation.” He framed Joby’s partnership with Uber as a way to bring air taxi service into a context users are already familiar with. Uber Investor Relations

Joby dropped its annual report on Friday, detailing its FAA certification route and its discussions with regulators from the UK, Japan, and the UAE. The report also flagged efforts to boost manufacturing, with a nod to the new Ohio facility bought in January.

The company is zeroing in on defense-adjacent work now. A hybrid turbine-electric demonstrator gets center stage, along with a partnership with L3Harris. Management says that pairing could factor into longer-range missions and government demonstrations planned for 2026.

Archer Aviation, Vertical Aerospace, and a handful of rivals are chasing similar regulatory green lights. Right now, shifts in the rulebook and new funding math are moving the needle across the sector, rather than direct sales numbers.

Still, there’s plenty that could go wrong. Certification delays, infrastructure setbacks, or even a single test going sideways would leave Joby burning through its reserves before seeing any revenue—or force it to hunt for fresh capital again.

Attention shifts to Joby, with traders watching to see if those gains stick once the bell rings. The company is expected to deliver fresh updates soon, as it hits the stage at Cantor Fitzgerald’s Global Technology & Industrial Growth Conference, March 10-11, then J.P. Morgan’s Industrials Conference on March 17.
