JPMorgan Chase & Co. Reduces Stake in Vicor Corp Below 5% Threshold

JPMorgan Chase & Co. filed a Schedule 13G/A on June 4, 2026, disclosing a reduced stake in Vicor Corp (VICR). As of the event date on May 29, 2026, the financial institution reported holding 1,556,989 shares of common stock, representing a 4.5% ownership interest. This reflects a significant decrease from the previously reported position of 2,106,728 shares, which accounted for a 6.2% stake in the company. The filing indicates that JPMorgan Chase & Co. holds sole voting power over 1,493,706 shares and sole dispositive power over 1,554,842 shares. The securities are held across several subsidiaries, including J.P. Morgan Securities LLC and J.P. Morgan Investment Management Inc. Because the ownership level has fallen below the 5% threshold, the filer marked the 13G/A to signify they are no longer a reporting person for this class of securities. The acquisition was made in the ordinary course of business and not for the purpose of influencing control of the issuer.
