This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.

The stock trades at a P/E ratio of 21.0x, above its 5-year median of 20.8x. The PEG ratio of 1.32 points to a price that reasonably reflects expected earnings growth.

The current price sits well above what projected cash flows justify, implying investors are paying for growth that has not yet materialized.

Financial quality is a concern. The Piotroski F-Score of 2/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
