Vertiv Holdings Co, Costco Wholesale, and one other stock are highlighted from a Low-Risk Leaders screener focusing on resilient companies with strong balance sheets. Vertiv Holdings Co (VRT), with a market cap of US$124.4b, provides power, cooling, and thermal management systems for data centers and communication networks, including those supporting AI. It generates most of its revenue from the Americas at about US$7.0b, with additional contributions of roughly US$2.4b from Asia Pacific and US$2.3b from Europe, the Middle East, and Africa, partly offset by around US$1.0b of intersegment sales. Vertiv stands out due to its role in AI data center buildouts, strong free cash flow, a sizeable backlog, recent acquisitions in cooling and services, robust earnings growth, and profitability metrics, though a high P/E multiple and reliance on a small group of big customers create sensitivity to AI infrastructure spending. Costco Wholesale (COST), with a market cap of US$404.9b, runs membership-only warehouse clubs and generates about US$293.6b in revenue, with roughly US$212.2b from the United States, US$39.7b from Canada, and US$41.8b from other international markets.
