Omeros Corporation (NASDAQ: OMER) opened over 150% up this morning after announcing a new licensing agreement worth up to $2.1 billion with the Bagsværd-headquartered Novo Nordisk.

According to OMER’s press release, this deal grants Novo exclusive global rights to develop and commercialise its MASP-3 inhibitor, zaltenibart (formerly OMS906), across all indications.

At its intraday peak, Omeros stock was up nearly 300% versus its year-to-date low on Wednesday.

Why OMER stock soared on Novo Nordisk deal

OMER stock is aggressively pushing to the upside today primarily because the Novo Nordisk deal is a major validation of the company’s scientific platform and commercial potential.

Zaltenibart targets MASP-3 – a key protein in the complement system’s alternative pathway – and has shown promising results in mid-stage trials for paroxysmal nocturnal hemoglobinuria (PNH).

Novo Nordisk’s commitment to initiate a global Phase 3 program signals confidence in the drug’s efficacy and market viability.

Meanwhile, the $340 million in upfront and near-term milestone payments provides Omeros with immediate liquidity, while the potential $2.1 billion total deal value and tiered royalties offer long-term upside.

For a company with a modest market cap and no approved blockbuster drugs, this agreement could reshape its financial trajectory and investor perception. This is what’s driving Omeros shares up today.

OMER shares are a speculative investment at best

Despite the euphoria, caution is warranted in jumping into OMER shares at current levels.

Omeros remains a micro-cap biotech with a history of cash burn and limited revenue.

Its financials show persistent operating losses, and its lead asset, narsoplimab, has yet to win regulatory approval.

While the zaltenibart deal sure is promising, it’s contingent on regulatory clearance and successful Phase 3 outcomes – neither of which are guaranteed.

Moreover, Omeros’ stock’s low float and minimal institutional interest makes it prone to volatility and speculative trading.

Without broader analyst coverage (only two Wall Street analysts cover OMER currently) or a clear path to profitability, Omeros’ cosmic run today could prove short-lived.

In fact, it’s already down some 20% versus its intraday peak at the time of writing.

Investors should weigh the potential windfall against execution risk and the firm’s thin pipeline beyond MASP-3 assets.

How to play Omeros at current levels

The Novo Nordisk agreement gives Omeros a rare lifeline and shot at relevance in the competitive biotech landscape.

However, long-term value creation will depend on clinical success, regulatory approvals, and disciplined capital management.

For now, OMER’s stock price rally reflects optimism – but sustaining it will require more than a headline.

Investors should monitor pipeline progress, cash flow discipline, and broader market sentiment before treating Omeros as a long-term winner.

Note that the biotech stock doesn’t currently pay a dividend, either to appear any more attractive for the income-focused investors.
