These written materials are submitted pursuant to Rule 14a-6(g)(1) promulgated under the Securities Exchange Act of 1934.

This is not a solicitation of authority to vote your proxy.

The shareholder asks all shareholders to vote by following the procedural instructions provided in the proxy materials.

Vote Against the Non Responsive Marsh & McLennan Director – 
Morton Schapiro, Chair of the Marsh & McLennan Governance Committee

The MMC Corporate Secretary, Connor Kuratek, is believed to have been dishonest in claiming MMC did not receive a 2025 shareholder proposal submitted to MMC.
 
Mr. Kuratek claimed he did not receive a 2025 shareholder proposal submitted to the same address that has been used successfully for communication with Mr. Kuratek before and since the 2025 proposal was submitted.
 
Mr. Morton Schapiro, Chair of the MMC Governance Committee was informed of the problem with Mr. Kuratek 2-times by FedEx letter. Mr. Schapiro failed to respond.
 
Mr. Schapiro should have had the time to respond since he does not serve on any other Board of Directors. Mr. Schapiro also received by far the most against votes of any MMC director at the 2024 MMC annual meeting – 36 million.
