Corporate valuation using multiples is one of the most popular corporate valuation approaches. In this book, the different steps of this valuation approach such as the selection of comparable companies or the choice of the reference variables are discussed. Then, the circumstances required for a sound valuation (e.g., the degree of efficiency of the equity market) are described. Additionally, the book gives insight on how the state of the industry and/or the company has an impact on the proper choice of the reference variables. Finally, it is shown how multi-factor models can enrich the universe of valuation models. While always maintaining the academic rigor, the author addresses practice-relevant topics and delivers hands-on solutions for typical valuation problems.
