Dividend Reinvestment and Stock Purchase Plan (DRPlus)

Ameren offers new investors and current shareholder the opportunity to invest in common stock through its Dividend Reinvestment and Stock Purchase Plan DRPlus.

Automatic Cash Investment

Current participants in DRPlus who wish to send monthly cash investments to purchase common shares may take advantage of our Automatic Cash Investment option. Participation in this service authorizes Ameren to withdraw the same amount each month from a shareholder's bank account to purchase additional Ameren stock, eliminating the need to mail a monthly check. The minimum investment per month is $25; the maximum investment is $30,000 per month. Participation in Automatic Cash Investment is optional.

Dividend Direct Deposit

Ameren shareholders can have their cash dividends directly deposited into their bank account each quarter by signing up for our Direct Deposit option. Investors no longer need to worry about lost, stolen or destroyed dividend checks―the funds are electronically deposited on payment date―even during vacation!
