However, it became one of the most notorious bankruptcies in the clean energy sector. This thesis examines the strategic decisions and financial mechanisms that shaped SunEdison’s trajectory, linking corporate strategy to its financial outcomes. Through a combination of financial analysis, case comparison, and literature review, the work explores the multiple narratives that emerged around the company’s collapse and seeks to identify the underlying causes behind its failure.engSunEdisonRenewablesEnergyFinanceStrategyLeverageYieldCosSemiconductormaster thesis204134390
