Hubbell's (HUBB) purchase of NSI Industries marks a notable advancement in the company's strategic aperture for HES segment, Oppenheimer said in a note Thursday.

The investment firm raised its 2026 adjusted earnings estimate for Hubbell to $19.85 per share from $19.70 and its 2027 estimate to $22.20 from $21.55, with NSI expected to add about $0.15 per share to Hubbell's adjusted earnings in 2026 and about $0.65 per share in 2027, based on cautious assumptions for cost savings and debt repayment.

Limited restructuring is expected because NSI is already well managed, but cost savings and sales opportunities are possible in data centers, renewable energy and distribution channels, Oppenheimer said.

Hubbell's Q1 book-to-bill ratio points to broader demand growth, with particularly strong orders in transmission and distribution markets, according to the note.

Oppenheimer kept its perform rating for Hubbell and said that its revised forecasts may have more upside than downside, especially in 2027.
