Datavault AI is trading 10.01% down at $0.08 after regular-session gains on October 28, with the after-hours decline coinciding with weakness in software stocks following mixed technology earnings; no company-specific catalyst was identified.
- ServiceNow fell sharply after its results; Alphabet declined, while Microsoft rose.
- An October 26 filing about inaccessible Bitcoin and financial-statement restatements remains important background, but available reports do not establish it as the cause of this move.
