Key Terms

private placement, warrants, securities purchase agreement, convertible bridge notes, +2 more

6 terms

private placement financial

"today announced the closing of a $2.15 million private placement of common stock and warrants"

A private placement is a sale of securities directly to a selected group of investors, typically institutions or accredited investors, instead of through a public offering. It lets a company raise money faster and with fewer regulatory steps; for existing shareholders it matters because the newly issued shares, often sold at a discount, increase the share count and can dilute their ownership.

warrants financial

"private placement of common stock and warrants, and an additional $2.69 million if cash warrants are fully"

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.

View in glossary

securities purchase agreement financial

"The Company entered into a securities purchase agreement with a group of investors for the private"

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.

convertible bridge notes financial

"from the conversion of convertible bridge notes previously issued to certain directors who had made"

A convertible bridge note is a short-term loan a company takes to 'bridge' its funding until a larger financing round, with the loan automatically converting into shares instead of being repaid in cash. For investors, it matters because it behaves like an IOU that will become ownership at a future price (often at a reduced rate compared with new investors), affecting future share count, potential upside, and dilution risk.

NYSE American financial

"Milestone Scientific Inc. (NYSE American: MLSS), a leading developer of computerized drug delivery"

NYSE American is a stock exchange where companies can list their shares to be bought and sold by investors. It functions like a marketplace, helping businesses raise money and providing investors with opportunities to buy ownership in these companies. Its role is important because it facilitates the trading of smaller or emerging companies, offering investors access to a broader range of investment options.

Form 8-K regulatory

"set forth in the Company's Current Report on Form 8-K filed with the Securities and Exchange"

A Form 8-K is a report that companies file with the government to share important news quickly, such as changes in leadership, major business deals, or financial updates. It matters because it helps investors stay informed about significant events that could affect the company's value or stock price.
