Is ARQ overvalued in 2026?

Arq Inc (ARQ) currently trades at $2.27 per share with a market capitalization of $98,125,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 40/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.

ARQ 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 0.8x, the market is valuing the company primarily on its revenue rather than its earnings.

Our discounted cash flow model estimates ARQ's intrinsic value at $13.59 per share, against the current market price of $2.27. This implies a margin of safety of +72.04%. A meaningful cushion exists against model error, making this a reasonable risk-adjusted entry.

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.

Bottom line: ARQ appears richly valued on our framework, with a Smart Value Score of 40/100. 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.
