Convertible Bonds in Corporate Finance

Convertible bonds are often used by companies seeking to raise capital without diluting existing shareholders as much as a direct equity offering would. They can be particularly useful for companies with volatile stock prices, like TSLA, SQ, and COIN, as the bond's fixed income component provides some downside protection to investors.

Convertible bonds offer a mix of income from the bond's coupon payments and potential capital appreciation if the underlying stock price increases.

Risks include the issuer's credit risk, interest rate risk, and the potential for the stock price to decline, reducing the conversion value.

Convertible bonds can initially lower a company's debt burden but may lead to equity dilution if the bonds are converted into stock.
