Series D Convertible Preferred Stock financial

"a total of 4,565 shares of Series D Convertible Preferred Stock"

Series D convertible preferred stock is a class of shares issued in a later-stage funding round that gives holders priority over common shareholders for payouts and often a fixed dividend, while including an option to convert those shares into common stock. It matters to investors because it affects who gets paid first if a company is sold or liquidates and can change ownership stakes and voting power when converted, similar to holding a safer ticket that can be exchanged for regular tickets later.

Warrants financial

"together with Warrants to purchase a total of 5,198,133 shares"

Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.

Securities Purchase Agreement financial

"the Company entered into a Securities Purchase Agreement and Registration Rights Agreement"

A securities purchase agreement is a written contract between a buyer and a seller outlining the terms for buying or selling financial assets such as stocks or bonds. It specifies details like the price, quantity, and conditions of the transaction, similar to a shopping list with agreed-upon terms. For investors, it provides clarity and legal protection when transferring ownership of these financial instruments.

Registration Rights Agreement financial

"Securities Purchase Agreement and Registration Rights Agreement with the investors"

A registration rights agreement is a contract that gives investors the option to have their ownership stakes officially registered with the government, making it easier to sell their shares later. This agreement matters because it provides investors with a clearer path to cash out their investments if they choose, offering more liquidity and confidence in their ability to sell their holdings when desired.

Section 4(a)(2) of the Securities Act of 1933 regulatory

"were exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933"

Rule 506(b) regulatory

"and Rule 506(b) promulgated thereunder"

Rule 506(b) is a U.S. securities exemption that lets companies sell shares or debt privately without full public registration, provided sales are primarily to accredited investors, up to 35 non‑accredited but financially knowledgeable buyers, and there is no public advertising or solicitation. It matters to investors because offerings under 506(b) usually include less public disclosure than registered securities—like buying from a private seller rather than a retail store—so buyers must do more of their own fact‑checking and rely on their financial sophistication.
