Vicor Corp. (NASDAQ: VICR) shares rose 10.84% to $197.36 at the time of publication after the power technology company unveiled plans to expand U.S. manufacturing capacity. Vicor is acquiring a 334,000-square-foot building on 66 acres in Merrimack, New Hampshire, and 54 acres in Hooksett. The sites will support ChiP Fab-2 and Fab-3, with a combined footprint of nearly one million square feet, expanding capacity beyond the company’s 320,000-square-foot ChiP Fab-1 in Andover, Massachusetts, which is nearing full utilization. Fab-2 has a one-year lead time to initial deployment. The expansion is intended to support OEMs and hyperscalers developing advanced artificial intelligence systems, increase U.S.-based sourcing and improve supply predictability through Vicor’s licensing model and broader ChiP fab network. Vicor said its Vertical Power Delivery technology is designed for AI applications constrained by multi-phase and integrated voltage regulators. Second-quarter backlog reached $380 million, up 26% sequentially and 145% from a year earlier, while cash and cash equivalents rose 12.2% sequentially to about $453.6 million as of June 30. The announcement comes as electricity availability, transformers and data-center readiness emerge as potential constraints on AI infrastructure growth. Technically, the stock remained below its 20-day, 50-day, 100-day and 200-day simple moving averages, despite a positive MACD histogram. Resistance was identified at $232.50 and support at $178.50.
