DBV Technologies shares rise 10.04% premarket as J.P. Morgan crosses 10% ownership threshold.

DBV Technologies surged 10.04% in premarket trading following a disclosure that J.P. Morgan Chase & Co. increased its stake to 13.03% of the company’s capital and voting rights as of January 29, 2026. The U.S.-based firm, which holds the shares indirectly on behalf of clients, crossed the 10% threshold through an increase in assimilated holdings. While the firm emphasized no intent to control or alter the company’s structure, the institutional investment signals confidence in DBV Technologies, likely driving the premarket rally.
