Key Terms

4 terms

Prospectus Supplement regulatory

"This Prospectus Supplement is being filed to update and supplement the information"

A prospectus supplement is an additional document provided alongside a company's main offering details, offering updated or extra information about a specific financial product being sold. It helps investors understand the latest terms, risks, and details of the investment, similar to how an update or revision clarifies or expands on original instructions, ensuring they have current and complete information before making a decision.

Senior Convertible Note financial

"we may issue upon the conversion of that certain Senior Convertible Note"

A senior convertible note is a loan a company issues that sits near the top of its repayment order and can be exchanged for the company’s stock under set conditions. Think of it like a high-priority IOU that also includes a coupon you can choose to turn into shares instead of taking cash back. It matters to investors because it affects who gets paid first if the company struggles and can dilute existing shareholders if the notes convert into new shares.

Waiver Agreement legal

"the Company entered into an amendment and waiver agreement (the “Waiver Agreement”)"

selling shareholders regulatory

"offer and sale, from time to time, by the selling shareholders identified in the Prospectus"

Shareholders who are offering some or all of their shares for sale in a market transaction or as part of an offering; they can be founders, early investors, employees, or other holders deciding to convert ownership into cash. Investors care because selling shareholders can change the ownership mix, increase the number of shares available to trade, and signal insiders’ confidence or need for liquidity—like a large owner putting a big parcel on the market, which can affect price and voting control.
