Neutral Impact 2 of 5 leadership Written later

James C. Moyer resigned from the Monolithic Power Systems board on October 21, 2024, and the board cut its authorized seats from eight to seven. The board also rebalanced its director classes by appointing Jeff Zhou as a Class I director, a move the company says is to achieve a more equal balance among the classes, and the filing says Moyer's resignation was not due to any disagreement with the company.
