Investment thesis
What must happen next
Omeros’ complement-centered first-in-class pipeline must deliver value-inflecting clinical or regulatory validation before ongoing R&D burn consumes its financing flexibility.WeakeningMateriality: High
FY2025 GAAP operating cash flow was negative $116.1 million, showing the company is still funding development rather than self-financing from operations. If validation arrives first, the equity can re-rate around drug value; if burn arrives first, future upside may accrue to new capital rather than current holders.
Watch: A lead complement-mediated disease program misses its pivotal or registrational endpoint, reducing the probability that current R&D burn converts into an approved product.

Open source ↗The pipeline only becomes a durable business if approvals, royalties, milestones, or product economics can absorb the fixed R&D base without requiring a proportionate increase in operating expense.HoldingMateriality: High
FY2025 GAAP operating income was a loss of $122.8 million, confirming that current operations are not yet self-sustaining. This is the path from scientific optionality to owner earnings; without operating leverage, even successful programs may not create attractive per-share value.
Watch: Commercial uptake after an approval is slow because physicians, payers, or treatment guidelines favor existing alternatives.
