Is OMER overvalued in 2026?
Omeros Corporation (OMER) currently trades at $11.67 per share with a market capitalization of $708,555,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 41/100. 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 8.6x, below its 5-year median of 8.8x. The PEG ratio of 0.81 suggests earnings growth is outpacing the multiple, a classic sign of undervaluation.
Looking at its own history, OMER is currently trading more expensive than 50% of the last 5Y on P/E. This places it in the 50th percentile of its historical range, a reasonable but unremarkable position.
Our discounted cash flow model estimates OMER's intrinsic value at $24.93 per share, against the current market price of $11.67. This implies a margin of safety of +54.95%. A meaningful cushion exists against model error, making this a reasonable risk-adjusted entry.
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: OMER appears richly valued on our framework, with a Smart Value Score of 41/100. 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 OMER overvalued?
OMER scores 41/100 on our Smart Value Score (Grade D), a weak overall profile. The DCF also shows a positive margin of safety, so price and fundamentals line up reasonably well.
What is OMER's fair value?
Our DCF model estimates OMER's intrinsic value at $24.93 per share, versus the current price of $11.67, a margin of safety of +54.95%. Fair value is the present value of the cash flows we project the business to produce, so a price below it means the market is pricing the stock below that conservative estimate.
What P/E ratio does OMER trade at?
OMER trades at a P/E of 8.6x on trailing twelve-month earnings, against a 5-year median of 8.8x. P/E is what you pay per dollar of profit, and sitting below its own median means the stock is cheaper than usual relative to its earnings.
Is OMER a buy based on valuation?
Our Smart Value rating for OMER is Sell, from a Smart Value Score of 41/100 that blends growth, quality, and valuation. The profile skews cautious, and a better price or clearer operating improvement would strengthen the case. This is research to inform your decision, not personalized financial advice.
