01 · Inspect first

What to inspect first 5

  1. Did-it-already-run check could not be completed from the supplied corpus because the requested Stooq price source was not present in the packet.

    The thesis appears to rely on this valuation assumption, but this pass did not verify it from the reviewed sources. The request listed PX_STOOQ_JOBY_2026-07-04, but no such file was present under sources/.

    Not confirmed in the reviewed corpus

  2. Peer valuation versus Archer/Beta/Vertical could not be grounded with a quotable source from the supplied corpus or accessible web results in this run.

    The thesis appears to rely on this valuation assumption, but this pass did not verify it from the reviewed sources. The packet lacked the price file and web search did not return a stable quotable market-cap/peer valuation page.

    Not confirmed in the reviewed corpus

  3. Joby still needs to comply with FAA eVTOL operational SFARs before adding its aircraft to its Part 135 certificate, creating launch-timeline risk.

    This challenges the risk part of the thesis, so it deserves review before supportive evidence gets much weight.

    Primary source: 10-Q, 2026-05-06

  4. Joby warns that FAA modifications to its G-1 basis, SFAR changes, or other regulatory revisions could delay certification and commercial launch.

    This challenges the risk part of the thesis, so it deserves review before supportive evidence gets much weight.

    Primary source: 10-Q, 2026-05-06

  5. Joby used $144.4 million of operating cash in Q1 2026, implying roughly 17 quarters of runway against $2.467 billion of liquidity before growth capex and business changes.

    Financing and runway can change dilution risk, timing, and how much room the company has to execute.
