• Registration of $300M ATM Program

  Alumis Inc. filed an S-3ASR to register an At-The-Market (ATM) offering, allowing the company to sell up to $300 million of its common stock from time to time through Cantor Fitzgerald & Co. as its sales agent. This program is for general corporate purposes, including clinical trial expenses, R&D, and capital expenditures.

• Strategic Timing Post-Positive Phase 3 Data

  This capital raise is strategically timed immediately after the company announced highly positive Phase 3 topline results for its lead candidate, envudeucitinib, in moderate-to-severe plaque psoriasis. This allows Alumis to strengthen its balance sheet and fund future development and commercialization efforts by leveraging favorable market sentiment.

• Potential Dilution from Offering

  The offering of up to $300 million represents a significant potential capital raise. If fully utilized, this program would result in substantial dilution for existing shareholders, as indicated by the pro forma dilution of $19.10 per share for new investors based on the March 18, 2026 closing price.

Alumis Inc. has filed an S-3ASR registration statement to enable an At-The-Market (ATM) offering of up to $300 million in common stock. This filing follows closely on the heels of the company's announcement of highly positive Phase 3 topline results for its lead candidate, envudeucitinib. While an ATM program introduces potential dilution and an overhang on the stock, the timing suggests a strategic move to capitalize on the recent positive clinical data. As a clinical-stage biopharmaceutical company, securing capital is crucial for funding ongoing research and development, preparing for a New Drug Application (NDA) submission in late 2026, and potentially commercializing its lead candidate. This capital raise strengthens the company's financial position to advance its pipeline and leverage its recent success.
