ISTR intrinsic value (DCF)

DCF-based fair value estimate vs current market price.

DCF has limited applicability for ISTR

Standard discounted cash flow models produce unreliable output for unprofitable or near-breakeven companies. Revenue-based multiples such as P/S and EV/Sales, combined with the historical valuation position above, give a more reliable read for this stock.

Intrinsic value calculated using discounted cash flow (DCF) model based on projected free cash flows, discount rate, and terminal growth assumptions. A positive margin of safety indicates the current price is below estimated fair value, providing a cushion against estimation error.

Is ISTR overvalued in 2026?

Investar Holding Corp (ISTR) currently trades at $27.75 per share with a market capitalization of $380,907,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 69/100. 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 12.2x, above its 5-year median of 10.8x.

Looking at its own history, ISTR is currently trading more expensive than 60% of the last 5Y on P/E. This places it in the 60th percentile of its historical range, a reasonable but unremarkable position.

A standard DCF model does not produce reliable output for ISTR 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.

Financial quality is a concern. The Piotroski F-Score of 0/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.

Bottom line: ISTR trades at a fair valuation on our framework, with a Smart Value Score of 69/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
