The company currently holds 292.97 M in liabilities with Debt to Equity (D/E) ratio of 1.63, which is about average as compared to similar companies. Bluebird Bio has a current ratio of 1.1, suggesting that it is in a questionable position to pay out its financial obligations when due. Debt can assist Bluebird Bio until it has trouble settling it off, either with new capital or with free cash flow. So, Bluebird Bio's shareholders could walk away with nothing if the company can't fulfill its legal obligations to repay debt. However, a more frequent occurrence is when companies like Bluebird Bio sell additional shares at bargain prices, diluting existing shareholders. Debt, in this case, can be an excellent and much better tool for Bluebird to invest in growth at high rates of return. When we think about Bluebird Bio's use of debt, we should always consider it together with cash and equity.
