Vertiv Holdings LLC (NYSE: VRT) saw its stock surge 5.21% in after-hours trading on Wednesday, following the release of its strong first-quarter 2025 earnings report and positive comments from prominent market analyst Jim Cramer.

The data center hardware firm reported impressive Q1 results, with enhanced revenue and a substantial net income turnaround. Vertiv's financial performance was highlighted by its negative accrual ratio of -0.16, indicating excellent cash conversion. The company generated free cash flow of $1.3 billion during the period, significantly outpacing its reported profit of $666.2 million. This strong cash generation has led to an increase in the company's full-year sales guidance, further boosting investor confidence.

Adding to the positive sentiment, Jim Cramer, in his recent appearance on CNBC, expressed his bullish stance on Vertiv. Cramer stated, "I think Vertiv's about to explode here," and emphasized the company's substantial business growth, noting a "huge acceleration from Q4 to Q1." He also highlighted the involvement of Dave Cote, former CEO of Honeywell, in Vertiv's operations. These comments from a respected market voice likely contributed to the after-hours stock price surge.
