Capital Markets Strategist

C3is completed a registered direct offering raising $2.0 million by selling 800,000 shares on October 9, 2025.

The transaction supplies immediate liquidity to C3is Inc. via sale of 800,000 common shares at $2.50 each for aggregate gross proceeds of approximately $2.0 million. The company states it will apply net proceeds and existing cash to general corporate purposes and working capital, which directly increases available short‑term funding for operations.

The primary dependency is how management allocates the proceeds; dilution from new shares is explicit and could affect existing ownership percentages. Legal and placement details are complete: the offering relied on an effective Form F-3 shelf and closed on October 9, 2025, with Aegis Capital Corp. as placement agent.

Watch for quarterly cash burn, any disclosure of specific uses of proceeds, and share count changes in the next periodic filings over the coming 90–180 days. These items will clarify whether the capital meaningfully extends liquidity or only covers short‑term needs.
