, 100% of all dividends on all shares held in your account on the dividend record date will be reinvested in additional shares of American Water common stock on the dividend payment date (less any applicable withholding taxes).

If you receive cash dividends on any shares in your account, you will receive payment by check unless you elect to have cash dividends deposited directly into your bank account. To authorize direct deposit, complete the appropriate sections of the Dividend Direct Deposit authorization form, which can be obtained from Equiniti. American Water encourages you to choose the direct deposit method of payment if you choose to receive cash dividends. The advantages of direct deposit over payment by check include more timely receipt of dividend proceeds and a reduced environmental impact due to avoidance of printed materials and transportation-related environmental impacts during delivery. The direct deposit method is also more cost efficient for American Water and aligns with our goals around improving our operating cost efficiency.

You may change your dividend reinvestment election at any time by completing a new enrollment form and delivering the form to Equiniti. Requests for changes must be received at least three business days prior to the next dividend record date to be effective for that dividend.

You should note that under U.S. federal income tax law, dividends are taxable to you even if your dividends are reinvested through the Plan. Equiniti will mail to you a Form 1099-DIV reporting your dividends (including reinvested

dividends) shortly after the close of each calendar year and also will report that information to the Internal Revenue Service (the “IRS”).

#### 5. How do I make an additional purchase?
After you have opened your Plan account, you may buy additional shares (including fractional shares) by check as often as weekly. Use the form attached to your Plan statement or transaction confirmation, or call Equiniti for additional forms. You also may arrange for automatic monthly purchases, or one-time purchases, using electronic funds transfer from your bank checking or savings account. Each method is described below. Regardless of the method used, each purchase you make must be for a minimum of $25.00, and all purchases may not exceed $200,000.00 in any calendar year. If you send a check or have authorized an electronic funds transfer in an amount that would cause you to exceed the $200,000.00 calendar year limit, your funds will be returned and no investment will be made.
