Joby Aviation Stock Is Down 54% This Year. Here's Why I'd Buy It Before 2027.

Joby Aviation shares have fallen more than 50% year-to-date amid heavy cash burn, dilution, rising operating costs, certification uncertainty, and a high valuation. The company expects $115 million-$125 million of revenue this year, supported by its Blade Air Mobility acquisition, while planned acquisition Resonant Sciences contributes more than $100 million in trailing revenue. Joby aims to begin pre-certification operations across 11 states in 2026 and could carry paying passengers as early as 2027, though commercialization remains contingent on FAA type certification and investors face substantial execution risk.

Analysis

JOBY's investable question is not whether eVTOL demand exists, but whether acquired revenue can reduce financing risk before certification-driven operating revenue arrives. Blade adds a customer-distribution and heliport-access channel, while Resonant potentially diversifies cash flow into defense; neither should be valued as evidence that the core aircraft economics or certification timeline are de-risked. The market is likely to discount acquired revenue heavily until management discloses segment margins, integration costs, recurring versus contract revenue, and consolidated quarterly cash burn.

Over the next 1-3 months, FAA milestones, fleet-production cadence, and any capital raise matter more than top-line guidance. A delayed certification pathway would extend the period in which JOBY must fund manufacturing, flight testing, and operations without meaningful unit economics, creating dilution and multiple-compression risk. Conversely, verified operating approvals, paid-service dates, or binding customer economics could re-rate the stock because the sector is priced primarily on probability of commercialization rather than near-term revenue.

The contrarian view is that the selloff may have already priced substantial execution risk, but the bullish narrative understates how hard it is to scale a regulated airline-like operation: pilot availability, battery-cycle economics, vertiport access, maintenance, insurance, and utilization must all work simultaneously. Archer Aviation (ACHR) is the clearest public competitive read-through; a certification or production setback at either company can reset sector probability-weighted valuations. The structural winner may ultimately be aerospace suppliers and defense customers rather than the first eVTOL operator, if aircraft manufacturers compete away passenger-service returns.

Key Decisions for Investors

• No directional core position until JOBY reports post-acquisition cash burn, liquidity runway, and segment-level gross-margin disclosure; treat these as gating data rather than accepting revenue guidance at face value.
• For high-risk tactical exposure, use a small long JOBY / short ACHR pair over the next 3-6 months only if JOBY demonstrates a clearly superior FAA or operating-permit milestone. Size for binary regulatory risk; exit if the certification timeline slips or quarterly cash use accelerates versus management guidance.
• Prefer defined-risk optionality over common equity for a 12-18 month certification catalyst: consider JOBY call spreads rather than outright calls after confirmation of sufficient cash runway. The thesis fails if a financing announcement materially dilutes shareholders or paid-service timing moves beyond 2027.
• Monitor ACHR production updates, FAA certification actions, and JOBY's cash balance each quarter. A sector-wide regulatory delay is a reason to avoid both names rather than rotate between them, as valuation support is probability-of-certification driven.
