Another View: Caution from Revenue Multiples

Looking at PubMatic from the perspective of its revenue ratio, the picture is less optimistic. The company currently trades at 1.8 times revenue, which is notably higher than both the US Media industry average of 1.0x and its own fair ratio of 0.8x. This premium suggests investors are already paying up for potential, leaving less margin for safety if growth stalls. If the market eventually adjusts toward that fair ratio, what would happen to today's upside?
