CVS Health is trading 7.95% lower at $85.20, down from its October 15 regular-session close of $92.56; no clear late-breaking catalyst directly explaining the after-hours decline was found. - A $315 million Justice Department opioid-case settlement was reported earlier in the week, but coverage said shares barely reacted at the time. - The October 15 company announcement concerned a healthcare collaboration; available evidence does not link either item to this after-hours move.
