more than one account, please be sure to submit a proxy for each proxy card you receive.

Holders of record may vote by mail by completing, signing, and
dating your enclosed proxy card and returning it in the accompanying pre-addressed envelope no later than the close of business on [ ], 2026 in order for your vote to be counted at the American Water
