Is NPO overvalued in 2026?
Enpro Industries (NPO) currently trades at $280.84 per share with a market capitalization of $6,119,000,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 44/100. 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 150.8x, above its 5-year median of 52.7x. The PEG ratio of 2.20 indicates the price has run ahead of the underlying growth rate.
Looking at its own history, NPO is currently trading more expensive than 96% of the last 5Y on P/E. This places it in the 96th percentile of its historical range, a zone where forward returns have typically been muted.
A standard DCF model does not produce reliable output for NPO under current conditions. For unprofitable or near-breakeven companies, revenue-based multiples such as EV/Sales and historical P/S percentile are more informative than intrinsic value calculations.
The Piotroski F-Score of 4/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: NPO appears richly valued on our framework, with a Smart Value Score of 44/100. At current levels the risk/reward is skewed against the buyer. A materially lower price or significant operational improvement would be needed to change the picture.
