Hook - thesis
If you want a pure speculative play on urban air mobility with a company that already has an aircraft, an app strategy, and a multi-quarter cash runway, Joby Aviation (JOBY) is a clean, tradable idea. The company is still losing big money - its most recent quarter (ended 09/30/2025) logged a net loss of $401.2m and a diluted EPS of -$0.48 - but it also carries almost $1.0bn in cash (reported cash: $978.1m). That combination of a funded roadmap plus a binary commercialization path (FAA approval, airline/regulatory partnerships, manufacturing ramp) makes JOBY attractive for disciplined speculators.
Why the market should care
Joby is not a concept stage startup. It has a certified-looking airframe in flight-test, an app/service ambition, and it already generates small revenue from flight services to the Department of Defense. The fundamental driver here is execution on three fronts: regulatory certification, demonstrable unit economics in early commercial routes, and proving manufacturing scale. If Joby clears those hurdles, the company converts from a deep R&D story into a revenue-generating platform with a scarcity premium - there are very few credible global eVTOL manufacturers with demonstrated flight hours and an integrated service plan.
Business snapshot
Joby builds an all-electric vertical take-off and landing aircraft designed for pilot-plus-four passengers, targeting up to 100 miles per charge and top speeds near 200 mph. The company intends to operate an app-based aerial ridesharing service - meaning Joby is trying to capture both aerospace manufacturing margins and platform/service economics. For now, the company has a single operating segment - flight services - and nearly all revenue comes from government flight services in the dataset period.
Recent numbers that matter
- Q3 (ended 09/30/2025) revenues: $22.6m - still immaterial relative to the development scale.
- Q3 net loss: -$401.2m; operating loss: -$181.7m; R&D: $149.2m - R&D remains the dominant cash drain, as expected for an aerospace rollout.
- Cash on hand (09/30/2025): $978.1m and total assets of $1.366bn; total liabilities: $469.9m (noncurrent liabilities listed at $395m) - a funded position, but not infinite runway.
- Q3 cash flow: net cash flow from operations was -$139.2m; investing -$123.1m; financing +$134.7m resulting in net cash flow -$127.6m for the quarter.
- Basic/diluted average shares in the latest quarter: ~844.6m shares - useful for valuation math below.
Valuation framing
Using the last trade/quote near $15.39 and the diluted/basic average share count (~844.6m), the market capitalization is roughly $13.0bn (15.39 times 844.6m shares = ~ $13.0bn). With cash of $978m and reported noncurrent liabilities around $395m, enterprise value sits in the ballpark of $12.4bn (market cap - cash + noncurrent liabilities - rough math, not a formal EV calculation). That is a forehead-smacking valuation given negligible run-rate revenue; Q3 revenue of $22.6m annualized is orders of magnitude below the valuation. In other words, JOBY today trades like a large option on successful commercialization rather than a traditional revenue multiple.
There aren't clean public comparables in the dataset to create an apples-to-apples multiple - most listed peers are unrelated or commodity/audit tickers. So valuation logic has to be qualitative: you're paying for the path to being one of the first scalable eVTOL operators and the scarcity of proven competitors who can both certify and build at scale.
Why this is a tradable speculative pick
There are three constructive elements that make Joby a reasonable speculative trade rather than a blind gamble:
- Balance sheet - almost $1bn in cash at 09/30/2025 provides a runway through multiple certification and early pilot phases. Quarterly operational cash burn (~$100-140m) implies the company can reach multiple near-term milestones without an immediate dilutive capital raise if trends hold.
- Execution visible via flight test and pilot programs - Joby is moving from pure R&D into pilot training and operational readiness (news flow indicates pilot training and presence at CES 2026), which are the near-term de-risking items investors watch.
- Binary but definable catalysts - FAA certification decisions, announced airline or operator partnerships, and the first commercial revenue ramps are discrete events that can re-price the story quickly.
Catalysts (what to watch)
- FAA certification milestones and timelines - any firm dates for type certification or airworthiness approvals will materially re-rate risk premium.
- Commercial launch pilots and city permits - announcements that Joby secured vertiport agreements, route permits, or city-level approvals.
- Airline/transport partnerships - signed PPA/PSA agreements with major carriers or ground operator partners that demonstrate demand and distribution for the app platform.
- Manufacturing/procurement milestones - proof points that Joby can transition to serial production without major cost overruns or supply-chain bottlenecks.
- Pilot training and initial revenue guidance - early revenue growth or guidance that moves Joby from a developmental accounting line to recurring flight service revenue.
Trade plan - entry, sizing, stops, targets
This is a high-volatility, event-driven trade. The suggested plan is explicitly for a speculative sleeve - a size you can tolerate losing in full if the binary outcomes go against you.
Entry: Scale in between $13.50 - $16.00. (Primary signal: price weakness into $13s or momentum above $16)
Initial position size: 2-4% of portfolio (speculative sleeve only).
Stop-loss: $11.00 hard stop (roughly -28% from $15.39 current quote) - discipline is critical.
Profit targets (tiered):
- Target 1: $22.00 (near-term event re-rate, ~+40% from $15.4)
- Target 2: $30.00 (material de-risking and early commercial traction, ~+95%)
- Target 3: $50.00 (meaningful certification + production scale/partnerships; big upside scenario)
Rebalance: Trim into strength at each target and raise stop to breakeven after partial fill.
Rationale: The $11 stop is below several recent consolidation lows and protects against a major reassessment of the financing or certification timeline. Targets are event-driven; $22 is achievable if a near-term certification milestone or major partner deal removes near-term binary risk. $30+ requires repeated, verifiable progress on operations and production economics.
Risks and counterarguments
Joby is a textbook high-risk, high-reward story. I list the principal risks and close with a direct counterargument to the bullish path.
- Regulatory risk - FAA type certification can slip or add onerous conditions that delay commercialization and raise costs. Certification remains the single biggest binary. A delay would lengthen runway needs and compress valuation quickly.
- Cash burn and dilution - Q3 operating cash outflow was -$139.2m. If burn accelerates or capital markets are unfriendly, Joby may need to raise equity at lower prices, diluting early holders.
- Manufacturing and supply-chain risk - transitioning from prototypes to serial production exposes supplier reliability and cost curves. Cost overruns erode the unit economics that justify lofty valuations.
- Market adoption and unit economics - even with certification, public willingness to pay, infrastructure buildout (vertiports), and pilot availability determine long-term TAM capture. If average fares or utilization disappoint, revenue multiples will compress.
- Competition / follow-on entrants - other OEMs and incumbents could commercialize competing designs, potentially fragmenting the early market and compressing margins.
Counterargument - some skeptics argue Joby is priced for perfection: certification on schedule, unit economics that support premium pricing, and a rapid city-by-city rollout. That is a lot to ask. The valuation implies the market is not paying for current revenue; it's buying optionality on a successful roll-out. If certification timelines stretch or if evidence of poor unit economics shows up in pilot routes, the stock can fall sharply.
What would change my mind
My bullish stance would be strengthened if Joby delivered three things in sequence: (1) a clear, dated FAA certification timeline or approval; (2) a marquee airline or transport partner committing to purchase or operate units at scale; and (3) early revenue guidance showing rapid uptake (quarterly revenue materially above the current single-digit millions). Conversely, repeated certification delays, a material acceleration in cash burn without incremental financing, or credible reports of serial production issues would make me move to the sidelines or short-term hedge positions.
Bottom line
Joby is a prime pick for speculative investors who can accept high volatility and binary outcomes. The company has meaningful cash (roughly $978m at 09/30/2025) and a funded runway to advance certification and initial commercialization steps, which creates tradable, event-driven opportunities. That said, the valuation treats Joby like a winner-take-most story today - and the next big moves will come from non-linear catalysts like FAA milestones, commercial launch pilots, and manufacturing scale. If you trade it, do so in small size, with strict stops, and a plan to realize gains at tiered targets if the story derisks.
