Why is a firm's credit rating significant?

A firm's credit rating is significant primarily because it provides an assessment of the company's creditworthiness, reflecting its ability to repay debts. When a firm's credit rating is lower, it indicates a higher perceived risk of default, meaning investors see it as more likely that the firm may face financial difficulties, including bankruptcy. This level of perceived risk directly impacts the firm's ability to borrow money and the costs associated with that borrowing.

A lower credit rating typically leads to higher interest rates demanded by lenders, as they want to be compensated for the increased risk they are taking.
