AMPH exhibits strong deterministic health with a Piotroski F-Score of 7/9, indicating solid operational efficiency and financial stability, though the absence of an Altman Z-Score raises concern about default risk. The stock trades at a discount to its Graham Number ($28.09) and intrinsic value ($14.21), suggesting undervaluation on a defensive basis. However, this is overshadowed by deteriorating fundamentals: negative revenue and earnings growth (YoY -1.8% and -31.0%), declining quarterly earnings, and a significant 36.4% drop in price over the past month. Insider selling activity further undermines confidence, with $0.95M in sales over six months despite no buy activity.
