On September 17, Vicor rose 11.72% in pre-market trading, trading at $204.09 per share, with turnover of $165,200.

On the news front, Vicor announced it has granted a non-exclusive license to a leading AI original equipment manufacturer, allowing the licensee to procure Vertical Power Delivery (VPD) modules protected by Vicor patents. The licensing deal marks a substantial milestone in the commercialization of the company's proprietary VPD technology, reinforcing market expectations around Vicor's competitive moat in AI compute power delivery.

The announcement arrives on the heels of several strategic moves. On September 11, Vicor disclosed the acquisition of a 334,000-square-foot building in Merrimack, New Hampshire, and a 54-acre parcel in Hooksett for construction of two new fabrication plants totaling nearly one million square feet to scale AI power delivery production. The stock surged over 10% on that news before pulling back approximately 9% on September 14 amid sector-wide selling and profit-taking. In late August, the board also authorized a $150 million share repurchase program. The convergence of VPD licensing, capacity expansion, and capital return initiatives has bolstered investor confidence in the company's AI-focused growth trajectory.
