Ways a company can restructure debt

Hello, I’m just wondering what some possible ways a company can restructure their current debt to make it more of a going concern. I’m not well versed in the fixed income department and was curious. A company I am looking at has a large debt load (bonds with 4-5 year maturities remaining) relative to its asset base and ability to generate cash flow in the near term. I’m assuming a debt for equity swap would be a last resort and I’m not sure what an early redemption or restructuring of the bonds would look like. Any insights would be appreciated, thanks in advance.
