Fermi is trading 4.1% down at $4.04, with no confirmed company-specific explanation for the October 1 decline. - Sharply higher Treasury yields may be a factor; major indices were each down less than 0.5%, so no clear market-wide cause is established. - Recent coverage describes shares as near a 52-week low amid execution and valuation concerns. - The TensorWave lease closing extension was announced September 22, not October 1, and is background rather than a confirmed catalyst.
