Missed Nvidia in 2009? This Rare Signal Is Flashing Again.<\/strong>\u00a0In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia.\u00a0For the first time in years, that same “Total Conviction” signal is flashing for a company 1\/100th the size of Nvidia.\u00a0Continue \u00bb<\/strong><\/a> <\/p>\n The logic is simple. Every new AI cluster needs enormous amounts of electricity and a way to keep thousands of chips from overheating. That demand flows to a different set of suppliers than the ones making the processors. <\/p>\n Two names sit near the center of that shift. Vertiv Holdings<\/strong> (NYSE: VRT) makes data-center power and cooling gear, and Bloom Energy<\/strong> (NYSE: BE) builds on-site fuel cells that generate electricity where the grid can’t keep up. Here’s what each one has going for it, and what could trip it up. <\/p>\n Vertiv sells the hardware buried inside a data center: power distribution, backup systems, and the liquid cooling that dense AI racks increasingly demand. When a hyperscaler builds new cloud computing<\/a> capacity, Vertiv’s equipment often goes in. <\/p>\n Demand is strong. First-quarter revenue rose 30% year over year to $2.65 billion, with organic sales up 23% and the Americas region growing 44% on data-center strength. <\/p>\n And profits are soaring. Adjusted earnings per share jumped 83% to $1.17, and adjusted operating margin expanded more than four percentage points to about 21%. <\/p>\n Looking ahead, Vertiv’s backlog more than doubled last year to $15 billion, roughly a year to 18 months of revenue booked in advance, and management raised its full-year outlook to about $13.75 billion in sales. <\/p>\n But one reason to tread carefully is valuation<\/a>. At about $319 as of this writing, up about 97% this year, Vertiv trades around 50 times forward earnings. That’s a rich multiple that assumes the build-out keeps compounding. And a stock priced this way has a long way to fall if AI spending slows. <\/p>\n 2. Bloom Energy: power when the grid can’t keep up <\/p>\n Bloom’s pitch is different. Its fuel cells generate electricity on-site, which matters because the grid in many regions simply can’t deliver power fast enough for a new AI campus. Rather than wait years for a utility connection, a developer can install Bloom’s systems and start running. <\/p>\n Story Continues <\/p>\n That need is translating into explosive growth. First-quarter revenue jumped 130% year over year to $751 million, and the company swung to a profit of about $71 million from a loss a year earlier. Operating cash flow turned positive, too. <\/p>\n The catalysts carry big names. Bloom recently expanded a master agreement with Oracle<\/strong> to supply up to 2.8 gigawatts of fuel cells, with an initial 1.2 gigawatts contracted and deployment underway. And it also scaled an AI-focused power financing partnership with Brookfield Asset Management<\/strong> to $25 billion. Additionally, back in April, management raised full-year revenue guidance to as much as $3.8 billion. <\/p>\n But Bloom is the more speculative of the two. The stock is up more than 180% this year and more than 800% over the past 12 months, and at about $245 it trades at well over 100 times expected earnings. <\/p>\n So which is the better bet? <\/p>\n The rotation itself makes sense to me. Powering and cooling AI is a durable, physical need — and it’s less crowded than the chip trade, which arguably leaves it more room to run. <\/p>\n But less crowded doesn’t mean cheap. <\/p>\n Both stocks already price in years of strong growth. What gives me pause is how much investors are paying for these growth stories. <\/p>\n Between the two, I lean toward Vertiv as the steadier way to play the theme. It’s profitable, spread across thousands of customers, and its backlog offers real visibility, even at a demanding price. But even it may be overpriced. <\/p>\n Should you buy stock in Vertiv right now? <\/p>\n Before you buy stock in Vertiv, consider this: <\/p>\n The Motley Fool Stock Advisor analyst team just identified what they believe are the\u00a010 best stocks<\/strong><\/a> for investors to buy now\u2026 and Vertiv wasn’t one of them.
