Vertiv Holdings (NYSE:VRT) Extends 2026 Rally After 64 Surge AI Data Center Demand and Cooling Backlog in Focus

Vertiv Holdings Co. NYSE VRT has continued its 2026 rally after the stock gained about 64 year-to-date, as investors track accelerating spending on AI data centers and power-and-thermal infrastructure. The company’s positioning in liquid cooling, power management and critical digital infrastructure has kept it in focus alongside broader AI capex trends from hyperscalers. Market participants are also weighing valuation against operating momentum and order visibility, including management commentary on backlog and margin trajectory.

Vertiv Holdings NYSE VRT has extended its AI-infrastructure-led advance in 2026, with shares up about 64 year-to-date as of March 24, 2026, a move that has put the company near the center of investor debate around which picks-and-shovels suppliers stand to benefit most from the ongoing AI data-center buildout.

The rally is being tied less to a single product cycle and more to a structural shift in how new AI-focused facilities are designed and provisioned. Higher rack densities driven by AI training and inference clusters place disproportionate stress on power delivery, power quality/backup, and cooling areas where Vertiv sells critical infrastructure such as power distribution and UPS systems alongside thermal management equipment.

Fundamentally, the most cited catalyst has been a sharp step-up in demand signals exiting 2025.

Market coverage summarizing Vertiv’s reported results highlighted orders up 252% year-over-year, a 2.9x book-to-bill ratio, and backlog expanding to roughly 15 billion up 109% year-over-year metrics that, if sustained, imply unusually strong revenue visibility for a hardware-and-services provider that historically has been more exposed to cyclical infrastructure spending.

Profitability and cash generation have also helped underpin the re-rating.

Vertiv delivered Q4 2025 revenue of 2.88 billion up 22.7% year-over-year and adjusted EPS of 1.36 vs. 0.99 a year earlier, alongside sharp improvement in free cash flow in that quarter.

Against that backdrop, investors are now weighing a more nuanced question after a 64% YTD surge: is VRT still the top AI infrastructure stock to buy, or has the market already priced in a best-case conversion of backlog into 2026-2027 revenue and earnings? The company’s 2026 outlook often cited in market commentary at roughly 13.25-13.75 billion of revenue and about 5.97-6.07 of adjusted EPS has raised the stakes.
