The relentless ATM issuance (6th 424B5 in 12 months) combined with pending dilutive transactions (Toyota, Resonant, Blade) signals that Joby's cash burn continues to outpace its ability to raise non-dilutive capital. With the stock down ~50% over 60 days, heavy insider selling, and 11.2% short interest, the path of least resistance is lower. Traders should watch for accelerated ATM sales on any bounce, which will cap upside. The Resonant Sciences acquisition closing conditions (regulatory approvals, pre-closing restructuring) add execution risk. Avoid catching this falling knife.
Price Chart
Executive Summary
Joby Aviation filed a 424B5 prospectus supplement for an at-the-market (ATM) equity offering of up to $750 million in common stock, underwritten by Morgan Stanley, J.P. Morgan, Allen & Co., and BofA Securities. This is the company's sixth 424B5 filing in the last 12 months, continuing a pattern of aggressive equity dilution to fund certification, manufacturing, and commercial operations. The filing also references the pending $500 million Resonant Sciences acquisition (partially stock-funded) and other dilutive instruments (Toyota tranche, Blade consideration, convertible notes), creating substantial future overhang. With a pre-money market cap of ~$8.7B, the $750M ATM represents ~8.6% dilution at the current price, and the stock has declined ~50% over the past 60 days amid heavy insider selling and high short interest.
Key Facts
- ATM offering of up to $750 million in common stock via Morgan Stanley, J.P. Morgan, Allen & Co., and BofA Securities.

- Agents receive up to 3.0% commission; estimated offering expenses of ~$415,000.
- Proceeds to fund certification, manufacturing, commercial operations, and general corporate purposes; may also fund acquisitions.

Financial Impact
Up to $750 million in gross proceeds from ATM; potential dilution of ~8.6% at $8.81/share; combined with other pending dilutive instruments (Toyota, Blade, Resonant, warrants, converts) creates substantial future overhang.
Risk Factors
- Continued dilution from ATM and pending transactions (Toyota, Resonant, Blade) will pressure stock price.
- Pre-revenue company with negative cash flows since inception; cash burn may accelerate.
- Heavy insider selling ($5M in 30 days) suggests management lacks confidence in near-term valuation.
- High short interest (11.2%) indicates strong bearish sentiment; potential for short squeezes but limited given ATM overhang.
- Resonant Sciences acquisition subject to closing conditions; failure could impair strategic plans.
- Regulatory certification risk: FAA type certification timeline uncertain; any delays would further pressure stock.
