Another View: Market Multiples Offer a Mixed Message

Taking a look at Seagate’s valuation through the lens of its price-to-earnings ratio reveals some tension. The company trades at 30.6x earnings, which is well above the global tech industry average of 22.2x and even peers at 60.1x. However, this is still notably below the fair ratio of 40.7x, indicating there is still a valuation gap the market could close or widen. What if the crowded optimism in AI storage leads to volatility before multiples ever catch up?
