Baird Identifies Top AI Infrastructure Stocks with Defensible Growth Drivers

Investment firm Baird has identified several electrical and AI infrastructure companies with strong competitive positioning in the artificial intelligence buildout. The firm’s analysis suggests these stocks offer attractive risk/reward profiles because their growth is tied to specific technological shifts, which could provide a "floor for growth expectations" even if broader capital spending moderates.

Baird's Key Selections

Baird's note focused on four companies poised to capitalize on distinct, durable trends within data center infrastructure:

• Littelfuse (NASDAQ:LFUS): Named as Baird's top pick, the company is positioned for the growth of high-voltage penetration in data centers, which yields 2-4 times higher content per megawatt. The firm highlighted that Littelfuse's design wins in the first half of 2026 were up more than double year-over-year, driven by its strategic relationships with hyperscalers and chipmakers.
• nVent Electric (NYSE:NVT): The company stands to benefit from the structural shift toward liquid cooling systems in data centers. Baird noted that nVent's ongoing capacity expansion provides visibility for potential upside from the first half of 2027 into 2028.
• Amphenol Corporation (NYSE:APH): Amphenol's exposure is linked to server replacement cycles rather than overall hyperscaler capital spending. Baird pointed to the company’s consistent gains in data connectivity content, leverage to high-voltage applications, and a larger fiber presence following its CommScope acquisition.
• Jabil (NYSE:JBL): The company's growth is centered on its deep customer relationships, with AWS being its largest client. Baird sees a potential path to 50% sustained growth into fiscal 2027, with significant opportunities from newly announced hyperscaler partnerships in fiscal 2028 and beyond.

The Investment Thesis

Baird's analysis, which follows recent market volatility in the sector, seeks to isolate companies with unique AI-related catalysts. The investment thesis is that demand for specialized technologies like advanced liquid cooling and high-voltage power distribution will remain robust, independent of the broader capital expenditure cycle.

This dynamic, according to the firm, creates a more defensible growth story for these select companies. By focusing on the essential upgrades required for next-generation AI data centers, investors can gain exposure to the sector's long-term expansion while potentially mitigating risks associated with general market fluctuations.
