Vertiv shares fall sharply: Is the AI rally cooling?

Vertiv's recent acquisition of UtilityInnovation Group has added another layer of volatility. The company agreed to pay $1.45 billion upfront in cash, with potential EBITDA-linked earnouts of up to $1.15 billion.

Vertiv has benefited from strong spending by hyperscalers on AI data centres, particularly demand for power and thermal-management solutions. But its elevated valuation has made the stock more vulnerable to profit-taking and shifts in investor sentiment.

TradingKey said Vertiv's trailing P/E was above 60x, leaving the stock sensitive to any slowdown or reprioritisation in AI-related capital expenditure. Analysts tracked by the publication had an average price target of about $331, with estimates ranging from $188 to $400.

Vertiv continues to benefit from the long-term AI data-centre buildout and has a substantial order backlog. However, investors are now closely watching acquisition integration, project execution, supply-chain pressures and hyperscaler spending.
