Echo IQ is trading 50% down at $0.64 after the FDA determined on September 9, 2026, that its EchoSolv HF heart-failure software was not substantially equivalent to an existing device under the 510(k) pathway.

  • The decision prevents clearance for commercial use at this stage.
  • The company says the 510(k) pathway remains open and is reviewing regulatory options.
  • Its FDA-cleared EchoSolv AS platform remains unaffected.
