### PROPOSAL ONE - ELECTION OF DIRECTORS
We have 10 directors nominated for election to serve until the 2026 Annual Meeting or until their respective successors have been elected and qualified. In the absence of contrary instructions, it is the intention of the persons named in the accompanying proxy to vote for the nominees listed below. If any nominee becomes unavailable to serve for any reason, the proxies solicited hereby will be voted for election of the person, if any, designated by the Board to replace that nominee or the Board may reduce its size. Proxies cannot be voted for a greater number of persons than the 10 nominees.

The following biographies summarize the director nominees’ tenure on the Assurant Board, current Board committee service, business experience, other board positions held during at least the last five year s and the particular experience and skills that led the Board to conclude that they should serve as directors. We have also included a chart that summarizes the skills and experience of each director, as well as demographic information.

The experience and skills we believe are important for our Board to have include:
