6 terms

Series A Convertible Non-Redeemable Preferred Stock financial

"Each share of Series A Convertible Non-Redeemable Preferred Stock ("Series A Preferred Stock") automatically converted into 8,128.1 shares of common stock..."

Certificate of Designations regulatory

"...subject to the terms of the Certificate of Designations, Preferences and Rights of Series A Convertible Non-Redeemable Preferred Stock of Azitra, Inc...."

A certificate of designations is a formal legal document that spells out the specific rights and rules attached to a particular class of stock, most often preferred shares. It tells investors who gets paid first, what dividends or conversion rights exist, and any voting or liquidation priorities—like an instruction sheet that decides which shareholders get preference if a company pays out or is sold. Those terms directly affect a security’s value and risk.

Beneficial Ownership Limitations financial

"...at 5 p. m. Eastern Time on June 16, 2026, subject to the... Certificate of Designations... and subject to the applicable Beneficial Ownership Limitations..."

Beneficial ownership limitations are rules or contractual caps that restrict how much of a company’s stock an individual or entity can be treated as owning or controlling for legal, regulatory or corporate-governance purposes. They matter to investors because such limits affect voting power, reporting obligations, takeover risk and the ability to increase a stake — like an elevator weight limit or a lane divider that prevents any one car from taking over the whole road.

Series B Common Stock Purchase Warrant financial

"Each share of Series A Preferred Stock was sold together with a Series B Common Stock Purchase Warrant to purchase shares of common stock..."

Series C Common Stock Purchase Warrant financial

"...and a Series C Common Stock Purchase Warrant to purchase shares of common stock (collectively, a "Security")."

Incentive Stock Options financial

"Includes 22,241 Incentive Stock Options held by Mr. Salva and exercisable within 60 days of June 16, 2026."

Incentive stock options are a type of employee stock option that gives eligible workers the right to buy company shares at a fixed price later on, often below future market value. They matter to investors because they align employee incentives with company performance, can dilute existing ownership when exercised, and create potential tax advantages for option holders if certain holding-time rules are met — think of them as a coupon to buy stock at today’s price with extra tax rules attached.
