US HB52

Requires the SEC within 180 days to amend rules limiting the number of shareholder proposals companies must include on proxy statements: 2 for non-accelerated filers, 4 for accelerated filers, and 7 for large accelerated filers

Restricts eligible shareholder proposals to only those with a "material effect" on a company's financial performance, explicitly excluding proposals that further environmental, social, political, or ideological goals

Defines "material" narrowly to exclude risks involving high uncertainty about long-term future events or those that are systemic, general, or not investment-specific in nature

Gives companies discretion to determine which proposals to include and in what order, requires disclosure of selection method to the SEC, and treats substantially similar proposals as a single proposal

Prohibits proposals submitted by board members from being included in the shareholder proposal count
