Shelf Registrations (S-3)

A shelf registration allows a company to register securities with the SEC and sell them at any time over a 3-year period. Think of it as a "loaded gun" — the company can issue shares immediately without further SEC approval. A large shelf relative to market cap is a major dilution risk signal.

💰

ATM Programs (At-The-Market)

An ATM program lets a company sell shares directly into the open market at prevailing prices, often without announcing each sale. These programs can run quietly, causing gradual price erosion as supply increases. Watch for companies with large ATM capacity relative to daily volume.

📜

Outstanding Warrants

Warrants give holders the right to buy shares at a set price. When stock price exceeds the exercise price, warrant holders convert — creating new shares and diluting existing shareholders. High warrant-to-float ratios indicate significant potential dilution ahead.

🔄

Convertible Securities

Convertible notes and preferred shares can be exchanged for common stock, typically at a discount. Toxic convertibles — where conversion price floats with market price — are especially dangerous, creating a "death spiral" where dilution drives the price down further.
