Citi defends Vertiv and Nvent stock amid liquid cooling concerns

Vertiv (VRT) and Nvent (NVT) shares experienced a sell-off following Amazon Web Services' (AWS) announcement of new liquid-cooled servers, sparking investor concerns about potential in-house cooling component production. Citi, however, defended both companies, characterizing the market reaction as "overdone" and highlighting their strong order visibility. The firm emphasized Vertiv's maintained competitive advantages and its positioning as a primary beneficiary of the projected growth in liquid cooling, while noting Nvent's extensive experience in the sector, ultimately viewing the VRT dip as a buying opportunity.

Analysis

A significant sell-off in Vertiv Holdings (VRT) and Nvent Electric (NVT), which saw their shares fall 6.63% and 2.31% respectively, was triggered by an Amazon Web Services (AWS) announcement regarding new liquid-cooled servers for NVIDIA's Grace Blackwell SuperChip. This sparked investor concern that AWS, a key customer, might vertically integrate and begin in-house production of cooling components. However, Citi characterized this market reaction as "overdone," citing strong near-term order visibility for both companies. The firm maintains that Vertiv's competitive advantages, including its market-leading power and thermal management portfolio and global service offerings, remain "largely intact." Citi views the VRT share price drop as a "buying opportunity," positioning the company as a "primary beneficiary" of the liquid cooling market's projected expansion from 15% to 30% of the total thermal market by 2027. For Nvent, Citi highlighted its two decades of experience as an "early-mover competitive advantage." This dynamic is set against the backdrop of Amazon's robust financial health, evidenced by 10.08% revenue growth and $126.14 billion in EBITDA, suggesting continued high-volume investment in data center infrastructure that supports the entire supply chain.

Key Decisions for Investors

• Investors should weigh the market's fear of AWS's potential vertical integration against Citi's assessment that Vertiv's and Nvent's competitive positions and order backlogs remain strong.
• The 6.63% decline in Vertiv shares could represent an attractive entry point for those with a bullish outlook on the AI-driven data center buildout, aligning with Citi's "buying opportunity" thesis.
• Monitor any future disclosures from Amazon regarding its sourcing strategy for cooling components, as confirmation of in-house production would validate the market's initial concerns and challenge the bullish case for VRT and NVT.
• Note the broad-based positive analyst sentiment for Amazon, with multiple price target increases, underscoring its pivotal role and sustained investment capacity in the high-growth AI and cloud infrastructure sectors.
