Why is ams OSRAM stock sliding today?
ams OSRAM (AOS) shares fell 6.6% to CHF 15.67 after Q3 2026 results and Q4 guidance. Q4 revenue forecast (€750M-€850M) and adjusted EBITDA margin (16% ±1.5%) missed expectations. Q3 revenue (€829M) beat consensus, but adjusted EBITDA dropped 19% YoY. The stock declined on cautious outlook and margin compression.
