May you please explain number 4 that you solved for me two days ago:Based on the information provided in the case, value Orangina?

Example:

Using the EBITDA multiple (Market capitalization divided by EBITDA), and Coca Cola and PepsiCo as comparable companies, we get a value of Orangina at $2690.2 million. If using sales multiple, Orangina will have a value of $3402.26 million. We also use APV method, assuming market risk premium at 7.5%, a spread of 2%, and interest grows constantly at 2% after 2010. The WACC we derive is 7.6%, and our estimate is $4777.75 million.
