AXT Announces Closing of Public Offering of Common Stock and Full Exercise of Underwriters’ Option to Purchase Additional Shares

Key Terms

underwritten public offering financial

An underwritten public offering is when a company sells new shares of its stock to the public with the help of a financial firm, called an underwriter. The underwriter agrees to buy all the shares upfront, reducing the company's risk, and then sells them to investors. This process helps companies raise money quickly and confidently from a wide range of buyers.

indium phosphide medical

Indium phosphide is a high-performance semiconductor material used to make chips, lasers and detectors that carry and process light and very fast electrical signals. Think of it as a specialized road surface designed for high-speed light traffic—better suited than ordinary silicon for fiber-optic communications, high-frequency electronics and some sensors. Investors care because demand and supply for this material affect companies in telecom, data centers, photonics and semiconductor supply chains, influencing costs, production capacity and technology competitiveness.

shelf registration statement regulatory

A shelf registration statement is a document a company files with regulators that allows it to sell shares or bonds quickly when it’s a good time to raise money. It’s like having a pre-approved plan ready so the company can act fast without going through lengthy paperwork each time they want to sell, making fundraising more flexible.

form s-3 regulatory

Form S-3 is a legal document companies use to register their stock sales with the government, making it easier and faster for them to raise money by selling shares to investors. It’s like having a pre-approved shopping list that lets a company quickly sell new shares when they need funds, without going through a lengthy approval process each time.

prospectus supplement regulatory

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.
