Alafi Capital bought 3,529,192 units in a $2.8M private placement at $0.8033 per unit, receiving common shares plus rights to Series A and Series B warrants. These warrants, with exercise prices of $0.8033 and $1.00, are subject to stockholder approval and beneficial ownership caps up to 19.99%, which moderates immediate dilution.

The structure links warrant expirations and extensions to milestones such as topline Phase 2 acute kidney injury data and FDA clearance of an IND for CM5480. Future impacts depend on achieving these clinical and regulatory events and subsequent warrant exercises.

Pre-Funded Warrant financial
"one pre-funded warrant to purchase one share of Common Stock (each, a "Pre-Funded Warrant""
A pre-funded warrant is a financial instrument that gives the holder the right to buy shares of a company's stock at a set price, with most of the purchase cost already paid upfront. It functions like a nearly fully paid option, allowing investors to secure shares quickly while minimizing the amount of additional money they need to invest later. This helps investors gain ownership rights efficiently, often used to avoid certain regulatory restrictions or to prepare for future stock purchases.
Series A Warrant financial
"one Series A warrant to purchase one share of Common Stock or a pre-funded warrant"
A Series A warrant is a contract issued alongside a company’s early funding round that gives the holder the right to buy a set number of shares later at a fixed price. Think of it like a coupon that lets an investor purchase stock at today’s agreed price even if the company’s value rises; it can boost potential upside for the warrant holder and create dilution for existing shareholders, so investors watch them when assessing ownership and future share value.
Series B Warrant financial
"one Series B warrant to purchase one share of Common Stock or a pre-funded warrant"
A Series B warrant is a tradable right issued alongside a Series B funding round that lets its holder buy a specified number of company shares at a fixed price for a set period. It matters to investors because exercising the warrant increases the total shares outstanding (dilution) and can be a cheap way to gain ownership if the company’s value rises — think of it like a coupon to buy stock later at today’s price.
beneficial ownership limitation financial
"would exceed a specified beneficial ownership limitation, not to exceed 19.99%"
A beneficial ownership limitation is a rule that caps the percentage of a company’s shares an investor can be treated as owning or controlling for voting, regulatory or tax purposes. It matters to investors because it can restrict how many shares a person or group can buy or vote, affect takeover chances, and influence share liquidity and value — like a speed limit that prevents any single driver from taking over the whole road.
Schedule 13D regulatory
"previously reported on the Schedule 13G filed with the Commission"
A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.
