OSIS intrinsic value (DCF)

DCF-based fair value estimate vs current market price.

DCF has limited applicability for OSIS

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 OSIS overvalued in 2026?

OSI Systems Inc (OSIS) currently trades at $231.92 per share with a market capitalization of $3,717,386,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 48/100. 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 25.8x, above its 5-year median of 24.2x. The PEG ratio of 1.64 points to a price that reasonably reflects expected earnings growth.

Looking at its own history, OSIS 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 OSIS 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: OSIS appears richly valued on our framework, with a Smart Value Score of 48/100. 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.

Frequently asked questions

Is OSIS overvalued?
