SMCI vs. VRT: Which Stock Has an Edge in the Liquid Cooling Space?

Super Micro Computer (SMCI) and Vertiv (VRT) are key players in the expanding data center liquid cooling market, essential for AI and high-performance computing. While SMCI is innovating with new liquid-cooled server technology and increasing shipments, it faces near-term headwinds from delayed customer upgrades and margin compression, leading to a projected 6.3% decline in FY25 EPS. Conversely, Vertiv is demonstrating robust growth, leveraging strategic acquisitions and NVIDIA collaborations, with projected FY25 revenue growth of 18.8% and EPS growth of 24.91%, positioning it as the stronger investment according to the analysis.

Analysis

The data center liquid cooling market is poised for significant expansion, with a projected compound annual growth rate (CAGR) of 12.8% through 2030, driven by the intense thermal demands of AI and high-performance computing. Within this secular growth trend, a clear divergence in near-term fundamentals appears between Super Micro Computer (SMCI) and Vertiv (VRT). While SMCI showcases technological leadership, ramping up production to over 2,000 direct liquid cooling (DLC) racks per month and launching its energy-efficient DLC-2 technology, it confronts significant headwinds. The company faces margin compression from competitors and delayed customer purchasing, culminating in a Zacks Consensus Estimate for a 6.3% year-over-year earnings decline in fiscal 2025. In contrast, Vertiv presents a more robust outlook, supported by strategic moves including the acquisition of CoolTera and deep collaboration with NVIDIA on platforms like the GB300 NVL72. This has translated into strong financial projections, with fiscal 2025 consensus estimates pointing to 18.8% revenue growth and 24.91% EPS growth. Despite SMCI's superior year-to-date stock performance of +65.2% versus VRT's +6.3%, Vertiv's stronger earnings trajectory and Zacks #2 (Buy) rank position it more favorably from a fundamental perspective compared to SMCI's #3 (Hold) rank.

Key Decisions for Investors

• Given Vertiv's projected 24.91% EPS growth and strategic alignment with NVIDIA, investors may consider it the more fundamentally sound investment in the AI cooling space, despite its higher forward P/S multiple of 4.5x.
• For Super Micro Computer, investors should be cautious of the disconnect between its strong 65.2% year-to-date stock appreciation and the identified headwinds of margin pressure and a projected 6.3% earnings decline.
• Monitor key risk factors for SMCI, particularly customer purchasing delays and competitive pricing in the server space, as a resolution to these issues could alter its near-term outlook.
• Consider the relative value and momentum trade between the two stocks, as VRT's strong fundamental outlook contrasts with SMCI's combination of recent stock outperformance and weakening forward earnings estimates.
