  • The shares also hit a new 52-week low around the same time, suggesting investors are still focused on valuation pressure and broader weakness despite the favorable legal headline.
  • Analyst sentiment remains mixed-to-cautious, with recent commentary pointing to a Hold consensus and a downgrade tied to sector and valuation concerns, which has kept upside expectations in check.
