Insights

Equity Capital Markets Analyst

Corbus priced a ~$75 million equity offering to fund clinical work; material dilution and cash runway effects follow.

Corbus Pharmaceuticals is selling 4,744,231 common shares and pre-funded warrants for 1,025,000 shares at a combined public offering price near $75 million, with a 30-day overallotment option. Proceeds will fund clinical development and general corporate needs, so the company converts market demand into near-term liquidity to support programs.

The move reduces share ownership for existing holders and may pressure per‑share metrics until clinical milestones arrive. Key dependencies include successful closing on or about November 3, 2025, receipt of net proceeds, and the pace of clinical spending. Watch closing confirmation, the underwriter option exercise within 30 days, and any disclosed changes to planned use of proceeds over the next 3–12 months.
