Corporate finance is a field of study that examines how businesses acquire and utilize their financial resources. Its primary objective is to achieve a sustainable long-term equilibrium, ensured through meticulous planning and programming processes, as well as the ability to control and manage risks associated with both ordinary and extraordinary operations. Due to these characteristics, corporate finance is relevant not only to entrepreneurs and enterprises but also to institutions, through market dynamics and financial flows; in fact, it aims to create a systemic balance increasingly oriented towards sustainability. The book offers a comprehensive and organic overview of the main aspects of corporate finance, presented in simple and accessible language, constantly drawing examples from real-world business scenarios: from financial analysis to investment evaluation; from financing decisions to extraordinary financial transactions; from treasury management to corporate governance aspects.
