Hubbell Incorporated (NYSE:HUBB) is one of the best grid modernization stocks to buy for AI infrastructure.

On May 4, Hubbell Incorporated (NYSE:HUBB) announced a definitive agreement to acquire NSI Industries for $3.0 billion in cash. NSI makes electrical fittings, connectors, components, and wire-management products for industrial, infrastructure, and commercial markets, and Hubbell said the deal would strengthen its Electrical Solutions portfolio. The company also said NSI’s products fit growth areas, including light industrial, datacenter, and network infrastructure applications, with NSI expected to generate about $570 million in revenue in 2026.

The acquisition gives Hubbell a more direct way to expand into the physical electrical products needed as AI infrastructure raises power density and connection complexity. That matters because the company’s grid-related demand is already strong. In its April 30 update, Hubbell said Grid Infrastructure net sales rose about 18% in the first quarter, while core utility transmission and distribution markets remained strong, with load growth supporting transmission and substation demand. The company also said Electrical Solutions’ growth was helped by strong datacenter and light industrial markets.

Hubbell Incorporated (NYSE:HUBB) manufactures utility and electrical solutions, including transmission and distribution components, connectors, switchgear, grid automation products, wiring devices, lighting controls, and related infrastructure equipment.

While we acknowledge the potential of HUBB as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk.
