Series B Non-Voting Convertible Preferred Stock financial
"Each share of Series B Non-Voting Convertible Preferred Stock is convertible into 1,000 shares of Common Stock"
A Series B non-voting convertible preferred stock is a class of company shares that gives holders financial priority—such as fixed dividends and first claim on assets if the company is sold—while not granting voting rights. It can be converted into regular common shares under set conditions, which matters to investors because conversion can increase upside participation but also dilute existing owners; the preference reduces downside risk like a safety buffer.
Agreement and Plan of Merger financial
"Received in exchange for common stock of Faeth Holdings Therapeutics pursuant to an Agreement and Plan of Merger"
An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.
Certificate of Designation of Preferences, Rights and Limitations financial
"Subject to certain conditions set forth in the Certificate of Designation of Preferences, Rights and Limitations of the Series B Preferred Stock"
Employee Stock Option (right to buy) financial
"Security title listed as Employee Stock Option (right to buy) with an exercise price of $1.16"
vesting financial
"Beginning August 1, 2022, the shares subject to the option vest in a series of forty-eight successive equal monthly installments"
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
