AmpliTech is booking a quantum backlog because cryogenic amplifier lead times for labs now exceed a year. Qubit readout needs amplifiers adding almost no noise at 4 kelvin, which very few shops build to spec and none can spin up in a quarter. Revenue is $24 million trailing at a 24% gross margin, with cash burn; July's $20.1 million rights offering funds the ramp but dilutes. The latest quarter fell 27% year over year; risks are lead times normalizing or Open RAN LOIs never converting. x.comÂ
