Joby Aviation Q1 Progress Highlights Certification Gating Risk Remains

What happened

Joby Aviation's Q1 earnings call touted progress in demonstration flights, certification milestones, and manufacturing expansion, but the company's 10-Q reveals Stage 4 'Testing & Analysis' is only 15% complete and Stage 5 at 6%, underscoring how much hard work remains. Revenue of $24.2 million from the Blade acquisition does little to offset a $110 million net loss and $144 million operating cash burn, keeping the story anchored to certification throughput. A massive $1.29 billion capital raise bolstered liquidity to $2.47 billion, but runway alone cannot substitute for dated regulatory milestones that investors need to see. Management's narrative of 'more than halfway through Stage 4' masks schedule fragility evidenced by a proxy-documented internal milestone miss that reduced PSU achievement to 38%. At $10.50, the stock prices an optimistic timeline; disciplined investors should wait for a specific for-credit Type Inspection Authorization start date and SR4 completion before upgrading from WAIT.

Implication

Investors should not read the Q1 call as de-risking certification. Stage 4 and 5 completion percentages remain low, and the company's own proxy showed internal schedule misses. The strengthened balance sheet buys time but doesn't accelerate the FAA process. The path to revenue still requires observable, dated milestones—SR4 completion and for-credit TIA testing start. Position sizing should reflect binary outcome risk; attractive entry is $8.50 with trim above $14. The thesis remains WAIT until those milestones are met.

Thesis delta

This Q1 update does not change the fundamental timeline. The core risk—Stage 4/5 throughput—remains unaddressed. The call provided incremental color but no new dates for TIA or SR4 completion, leaving the WAIT rating and 3-6 month re-assessment window intact.
