Another View: Looking at Market Multiples

While the analyst consensus points to Infineon being undervalued, market multiples paint a different picture. Infineon's price-to-earnings ratio stands at 41.8x, which is notably higher than both its industry average of 33.5x and its peers at 22.1x. Even compared to the fair ratio of 32x, the current valuation is elevated.
