Joby Aviation: Is It Finally Time to Buy Below $7?

Joby Aviation shares have fallen more than 50% year-to-date and trade roughly 67% below their 52-week high, despite flight demonstrations, progress through the FAA's final Type Inspection Authorization stage, and a planned roughly $500 million acquisition of Resonant Sciences. The company generated about $36 million of quarterly revenue, holds approximately $2.3 billion in cash and short-term investments, and expects around $400 million of second-half 2026 spending, while continuing to burn roughly $200 million per quarter. Commercial air-taxi approval, fleet scaling, consumer adoption, weather and maintenance constraints, and accident risk remain key obstacles, limiting the near-term investment outlook.

Analysis

JOBY's valuation is now primarily an execution-duration and dilution problem, not a near-term technology-readiness debate. At the indicated cash-use rate, the company has several years of runway, but commercial launch, fleet production, vertiport access, and operating certification are sequential gates; any slippage converts directly into a higher probability of equity issuance before meaningful air-taxi cash flow. The acquisition also shifts capital allocation toward defense-adjacent optionality, which may diversify revenue but risks obscuring the standalone economics and capital needs of the passenger network.

TM is a quieter beneficiary if eVTOL production milestones hold: its manufacturing involvement offers real-option exposure to advanced mobility without JOBY's concentrated certification and funding risk. Conversely, Archer Aviation (ACHR) is the more relevant public read-through and likely trades in sympathy on FAA timing, despite having independent aircraft, supplier, and commercialization risks. Blade's existing aviation customer base could reduce demand-acquisition friction, but it does not establish that eVTOL unit economics can absorb weather disruption, maintenance downtime, insurance, and premium-route infrastructure costs.

Near term, JOBY can rally sharply on any externally verified FAA conformity-test completion or operating-certification milestone because the share base is positioned skeptically. Over the next 1-3 months, however, the decisive data are quarterly net cash use, production-capex commitments, purchase obligations, and management's first credible delivery cadence—not demonstration activity. Over 6-18 months, a certification delay, safety event anywhere in eVTOL, or a manufacturing ramp that fails to lower unit cost would compress the sector's terminal-value assumptions simultaneously.

Contrarian view: the stock decline may be underestimating defense optionality, but investors should not capitalize it until Resonant's revenue, margins, backlog, and incremental funding requirements are disclosed. The more likely consensus error is treating certification as the main de-risking event; certification would validate airworthiness, not utilization, route density, customer willingness to pay, or return on deployed aircraft capital.

Key Decisions for Investors

• No directional JOBY long ahead of the next cash-flow and guidance update. Reassess only if cash burn remains at or below management's implied run rate while the company provides a dated production/delivery schedule; a burn-rate step-up or new equity authorization falsifies the improved-risk narrative.
• For a tactical certification-milestone trade, use a defined-risk JOBY call spread 3-6 months out rather than common equity. Size small: upside is a milestone-driven rerating, while premium loss is acceptable if regulatory timing slips; avoid selling naked puts given financing and safety-event gap risk.
• Express relative advanced-mobility exposure through long TM versus short a basket of pre-revenue eVTOL beta, led by JOBY/ACHR where borrow permits. The thesis is that TM retains upside from supplier/manufacturing participation while limiting direct exposure to certification delay and future dilution; close if TM's manufacturing commitment weakens or JOBY demonstrates sustained production execution.
• Set event alerts for FAA Type Inspection Authorization completion, FAA operating-certification progress, quarterly cash use above roughly $250 million, and any disclosed fleet purchase/delivery deferral. These are more investable signals than flight demonstrations and should determine whether to add or remove eVTOL exposure.
