Hubbell's stock experienced a sharp decline of 7.38% during pre-market trading on Tuesday, following the release of its fourth-quarter and full-year 2025 financial results.

The electrical equipment manufacturer reported strong quarterly performance, with adjusted earnings per share beating analyst estimates and revenue showing solid growth, primarily driven by robust demand for data center products. However, investor sentiment turned negative as the company issued its adjusted earnings per share guidance for fiscal year 2026, which came in at the lower end of market expectations. The guidance range suggests a potential slowdown in earnings growth compared to previous periods, leading to the significant pre-market sell-off.
