SUPN ▼ -0.1% - Supernus Pharmaceuticals, Inc. $SUPN - Chloe Kim Teams Up with Qelbree®, the #1 Prescribed Branded Non-Stimulant ADHD Treatment*, to Help Empower People Navigating ADHD Supernus Pharmaceuticals' stock was essentially flat today despite the company announcing a partnership between Olympic athlete Chloe Kim and its Qelbree medication. The collaboration appears designed to raise awareness around Qelbree, which the company identifies as the leading prescribed branded non-stimulant ADHD treatment. The minimal stock movement suggests investors viewed the marketing initiative as routine business activity rather than a material catalyst for the company. 31-AUG-2026 08:30 AM ET
