2018 Target PSU and RSU Award Formula for Ameren Corporation Named Executive Officers

Summary

This document outlines how Ameren Corporation will determine the number of 2018 Performance Share Unit (PSU) and Restricted Stock Unit (RSU) awards for its named executive officers. The awards are calculated based on each officer's base salary as of January 1, 2018, multiplied by a specified long-term incentive target percentage, and then divided by the average closing price of Ameren stock over the thirty trading days before the grant date. The formula allocates 70% of the incentive to PSUs and 30% to RSUs, with specific target percentages listed for each executive.
