 shares to be voted. The intermediary will vote shares held
by you in “street name” in accordance with your voting instructions, as indicated on your signed voting instruction form or by the instructions you provide via the Internet or by telephone. Absent such instructions, NYSE rules prohibit
an intermediary from exercising discretion to cast a vote with respect to your shares held in street name on non-routine matters. In that case, a proxy submitted by the intermediary with respect to your shares would indicate that the intermediary is
unable to cast a vote with respect to the matter, which is commonly referred to as a “broker non-vote.” It is expected that all proposals to be voted on at the American Water special meeting will
be non-routine matters on which intermediaries are not allowed to vote unless they have received voting instructions from their customers.

If you hold
shares of American Water common stock in “street name” and wish to vote your shares virtually at the American Water special meeting, you may vote online during the meeting only as an authenticated shareholder with a 16-digit control number by visiting www.virtualshareholdermeeting.com/AWK2026SM, entering your 16-digit control number, and following the
on-screen instructions. The availability of online voting at the American Water special meeting for shares held in “street name” will depend on your intermediary’s specific voting procedures.
Please contact your intermediary for information.
