Vertiv (VRT) shares plummet 6%: Are AI infrastructure stocks still worth buying?

Core Points

Vertiv Holdings (VRT) shares fell sharply in Wednesday trading, down 6.7% to close at $245.17 and open at $259.10.

The focus of investor concerns is the company's $1.45 billion acquisition of Utility Innovation Group (UIG), but the transaction lacks transparent financial indicators to support it.

Second-quarter 2026 results were disappointing, with revenue approximately US$110 million lower than analysts 'expectations.

New Massachusetts regulations require local approval for data center construction, fueling concerns across the industry.

Analyst Mike Khouw maintained an optimistic view, emphasizing the company's strong earnings trajectory and attractive PEG valuation.

Vertiv Holdings (VRT) shares plummet: Does AI infrastructure still have buying value?

Vertiv Holdings (VRT) experienced a significant decline on Wednesday. The stock plunged 6.7% in early trading to $245.17 as market participants digested the uncertainty caused by mergers and acquisitions, continued weak quarterly results and broader market weakness.

The stock price correction follows the company's plan disclosed on September 1: Vertiv plans to acquire Utility Innovation Group (UIG) for an initial consideration of approximately US$1.45 billion, which could rise to approximately US$2.6 billion if an earnings payment clause is included. However, the challenge is that the company has not disclosed UIG's sales data, order backlogs or operating cash flow indicators, making it impossible for market participants to fully assess the rationality of the transaction.

The acquisition is based on projected 2027 EBITDA at a valuation multiple of approximately 13 times, relying on forecasts rather than historical financial performance. The deal structure has sparked suspicion among investors, with many demanding specific financial data before backing the nearly $2.6 billion commitment.

M & A uncertainty exacerbates revenue disappointment

Vertiv's forward valuation is at a high level, trading at about 63 times forward earnings expectations, providing a minimal buffer for negative developments. When highly valued stocks encounter execution challenges or transparency issues, share prices often fall quickly and sharply.

Adjusted operating profit margin reached 22.6% in the second quarter, an expansion of 410 basis points, demonstrating the organization's ability to achieve large-scale profitability. However, the revenue gap was followed by a major acquisition with limited transparency, triggering investor caution.

Previously, the governor of Massachusetts issued an administrative order requiring data center projects to obtain local municipal authorization before starting. The move introduces additional regulatory concerns for a wide range of AI infrastructure companies and puts pressure on industry peers, including Vertiv.

The overall market context also failed to provide support. In Wednesday trading, the S & P 500 fell 0.6% and the Nasdaq fell 0.8%, reflecting risk aversion, which had a particularly disproportionate impact on high-beta securities. Vertiv has a beta of about 2.07, indicating that its volatility is typically about twice that of the broader index.

Despite the sell-off, bullish arguments remain

Not all market participants have given up their positions. On CNBC's "Options Action" program, veteran trader Mike Khouw made a constructive argument against VRT, emphasizing earnings growth prospects and a PEG ratio below 1 to justify the stock's premium multiple. He established an option position that extends into early 2027.

Khouw's views emphasize that Vertiv, as a key provider of AI data center power infrastructure and thermal management systems, is still on a sustainable growth track even after growth of more than 1,000% over the past five years.

The company joined the S & P 500 in March 2026, launching a stable passive fund accumulation, which provided support during the AI sector adjustment period prior to this year.

As of press time, the trading price of VRT was US$245.17, down from the day's opening price of US$259.10.
