Is LFUS overvalued in 2026?
Littelfuse Inc (LFUS) currently trades at $465.86 per share with a market capitalization of $11,939,903,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 50/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
LFUS currently has no meaningful P/E ratio, which typically signals that the company is unprofitable, near breakeven, or emerging from a loss-making period. With a P/S ratio of 4.8x, the market is valuing the company primarily on its revenue rather than its earnings.
Looking at its own history, LFUS is currently trading cheaper than 100% of the last 5Y on P/E. This places it in the 0th percentile of its historical range, a level that has historically coincided with attractive entry points.
Our discounted cash flow model estimates LFUS's intrinsic value at $225.69 per share, against the current market price of $465.86. This implies a premium to fair value of -58.57%. The current price sits well above what projected cash flows justify, implying investors are paying for growth that has not yet materialized.
The Piotroski F-Score of 5/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: LFUS trades at a fair valuation on our framework, with a Smart Value Score of 50/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.

Is LFUS overvalued?
LFUS scores 50/100 on our Smart Value Score (Grade C), a mixed overall profile. On valuation specifically, the DCF puts intrinsic value below the current price, so the stock is expensive on cash flow today. The score reflects growth and quality carrying it, not a cheap entry point.
What is LFUS's fair value?
Our DCF model estimates LFUS's intrinsic value at $225.69 per share, versus the current price of $465.86, a margin of safety of -58.57%.
