Is MTX overvalued in 2026?
Minerals Technologies Inc (MTX) currently trades at $66.98 per share with a market capitalization of $2,095,277,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 45/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
MTX 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 1.0x, the market is valuing the company primarily on its revenue rather than its earnings.
Looking at its own history, MTX 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 MTX's intrinsic value at $85.19 per share, against the current market price of $66.98. This implies a margin of safety of +12.95%. The stock is priced close to its estimated fair value, offering limited upside without further operational improvement.
Financial quality is a concern. The Piotroski F-Score of 3/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
Bottom line: MTX appears richly valued on our framework, with a Smart Value Score of 45/100. 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.

Is MTX overvalued?
MTX scores 45/100 on our Smart Value Score (Grade C), a weak overall profile. The DCF also shows a positive margin of safety, so price and fundamentals line up reasonably well.
