The document summarizes a comparable companies analysis valuation of GM using multiple automotive companies. Key steps included selecting comparable public companies, collecting financial data, calculating ratios and growth rates, determining trading multiples based on forward EV/EBITDA, and applying those multiples to GM's EBITDA to calculate an implied valuation range. GM's implied valuation range was then compared to its current enterprise value to assess whether it was under or overvalued based on the comparable company analysis.
