At March 31, 2025, the Company had approximately $6,525,000 of cancelable and non-cancelable capital expenditure commitments, principally for manufacturing equipment.

As previously reported in its Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K, the Company is the defendant in a patent infringement lawsuit originally filed on January 28, 2011 by SynQor, Inc. (“SynQor”) in the U.S. District Court for the

Eastern District of Texas (the “District Court”). SynQor alleged that certain Vicor products infringed certain United States Patents owned by SynQor.

On October 26, 2022, after a trial in the District Court, the jury returned a verdict finding that the Company willfully infringed one SynQor patent, and awarding SynQor damages in the amount of $6,500,000.

On May 20, 2024, the District Court issued an Amended Corrected Final Judgment, awarding SynQor actual damages of $6,500,000, enhanced damages of $4,500,000, costs in the amount of approximately $87,000, attorney fees in the amount of $9,500,000, and pre-judgment interest of approximately $5,400,000, for a total judgment of approximately $26,000,000.

On May 22, 2024, the Company filed an appeal of the District Court’s judgment to the United States Court of Appeals for the Federal Circuit. That appeal remains pending.
