On September 14, Vicor declined 5.11% overnight, trading at $187.8 per share, with turnover of approximately $894,700.

The pullback follows a sharp single-day rally of over 10% on September 11, when Vicor announced the acquisition of a 334,000-square-foot building in Merrimack, New Hampshire, along with a separate 54-acre parcel in Hooksett to expand chip fabrication capacity. The two new facilities are expected to total nearly one million square feet, supporting scaled production of power delivery technology for artificial intelligence applications. With initial deployment of ChiP Fab-2 carrying an estimated one-year lead time, market participants appear to be locking in gains from the prior surge.

Adding to the downward pressure, the broader Electrical Components and Equipment sector weakened notably. Among sector peers, Vertiv Holdings fell 4.78%, Eaton declined 2.2%, Rockwell Automation slipped 0.71%, and Emerson edged down 0.45%, reinforcing the sector-wide drag on Vicor shares. Separately, Vicor had recently filed a Section 337 investigation petition with the US International Trade Commission targeting several companies over alleged patent infringement in vertical power delivery systems, and its board approved a $150 million share repurchase program in late August.
