Horizon Technology Finance Corporation Prices Offering of 7.00% Notes due 2028

Key Terms

registered direct offering financial

A registered direct offering is a way for a company to sell new shares of its stock directly to select investors with regulatory approval. This method allows the company to raise funds quickly and efficiently without needing a public auction, similar to offering exclusive access to a limited number of buyers. For investors, it often provides an opportunity to purchase shares at a favorable price, while giving the company immediate access to capital.

make-whole premium financial

A make-whole premium is an extra payment a borrower must give bondholders when repaying debt early to compensate them for lost future interest; think of it as a lump-sum “catch-up” to leave lenders financially where they would have been if the loan had run its full term. It matters to investors because it affects how much they receive on early redemption and influences a company’s decision to refinance or repay debt, altering bond value and expected returns.

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.

book-running manager financial

A book-running manager is the lead organizer responsible for coordinating a large financial sale, such as issuing new stocks or bonds. They oversee preparing all necessary documents, setting the sale’s price, and finding buyers, much like a concert promoter arranging a major event. Their role matters to investors because they help ensure the offering is successfully sold at the best possible terms.
