JPMORGAN CHASE & CO files DEFA14A

This supplemental proxy filing from JPMorgan Chase & Co. (JPM) is a letter to Glass Lewis, responding to their research report and recommendation to support "Proposal 5: Shareholder Proposal Regarding Independent Chair" at the 2026 Annual Meeting. JPM argues that Glass Lewis's analysis for Proposal 5 should be revised, stating that the current Board leadership structure, with a combined CEO/Chair and a strong Lead Independent Director (LID), has delivered strong financial performance and effective oversight.
