Copa Holdings is experiencing currency weaknesses, flight suspensions, and delivery delays, which have led to a 15% stock decline since May. However, the company has strong operating margins above 20% and has reduced unit costs, indicating potential for margin recovery. Despite revised down EBITDA estimates, the stock is trading below its median EV/EBITDA multiple, making it undervalued compared to peers. This suggests a positive short-term impact on the stock price as the market may recognize its undervaluation.
