QTREX Quantum is trading at $1.01, with a change of -8.18% after hours; no specific catalyst for the decline was identified.
- Earlier, QTREX Quantum announced independent testing showing over 100 dB channel isolation at 20 millikelvin and said it was finalizing a binding commercial agreement.
- That announcement was associated with Friday morning strength, not an explicitly reported cause of the after-hours drop.
- Major U.S. indices were higher, and available reporting does not establish why shares reversed after the regular-session close.
