What Is Driving Growth
Obesity treatment demand adds 4.2 percentage points to annual growth, as strong weight loss in clinical programs gives patients and doctors a reason to start therapy and payers widen coverage. Label expansion into obstructive sleep apnea, heart failure and other indications widens the patient pool and gives payers clinical outcomes to cover, which makes growth more durable than demand driven by weight loss alone. Manufacturing scale-up adds 2.2 points, since sterile fill-and-finish and autoinjector assembly are scarce skills. Price pressure and payer limits are the largest restraint, removing 2.4 points, while competing incretin products and compounded or counterfeit supply add further pressure on net price.
