convertible notes

A debt instrument that can be converted into a predetermined number of equity shares of the issuing company.

Convertible notes are hybrid financial instruments that start their life as corporate debt but contain an embedded option allowing the holder to convert the principal balance into a predetermined number of equity shares. Typically issued by early-stage startups or public companies seeking lower-cost funding, these notes pay regular interest (coupons) and have a set maturity date. If the company's stock price rises above a specified threshold, known as the conversion price, the noteholders can choose to swap their debt for equity, participating in the company's growth. For issuing companies, convertible notes are an attractive way to raise capital at a lower interest rate than traditional corporate bonds. Investors accept this lower yield in exchange for the equity upside potential. For investors, these instruments offer a degree of downside protection because they hold a debt claim on the company's assets if the equity fails to perform, combined with the unlimited upside of a stock option. From the perspective of existing public equity investors, convertible notes represent a potential dilution risk. If the stock price rises and the notes are converted, the total outstanding share count increases, which can dilute earnings per share (EPS). Analysts and investors must monitor a company's diluted share count to understand the potential impact of these outstanding hybrid securities.

Company A issues a convertible note with a face value of $1,000 and a conversion price of $50 per share. This means the note can be converted into 20 shares of stock ($1,000 / $50). If Company A's stock price rises to $70, the investor can convert the $1,000 note into 20 shares, which are now worth $1,400 (20 shares $70), securing a $400 gain.
