Contrary to a common misconception widely propagated by the mainstream media, company valuation is not about applying "methods" and mixing them to arrive at a random "range." In reality, it is a rigorous professional practice that relies on a series of precise operations, emulating those implemented by real market players. This training aims to propose the various phases of this methodology so that participants can replicate it or simply ensure that the "experts" they consult have correctly applied it. It applies to all companies except for micro-enterprises and start-ups, which have specific issues.
