Nyxoah is trading at $0.81, down 9.70%, with its October 19 cut to 2026 revenue guidance remaining the clearest company-specific explanation for the decline. - The company lowered its 2026 revenue outlook to €33–35 million from €36–40 million. - Preliminary third-quarter revenue was approximately €9.2 million. - Broader risk sentiment is weak, but available evidence does not establish it as the primary driver; no distinct October 22 company announcement was identified.
