olders of record may submit their proxy by telephone by calling (800) 690-6903. Holders of record may
submit their proxy via the Internet (see proxy card for instructions). In order for holders of record to vote their shares by telephone or via the Internet, they will need the 16-digit control number
included on the enclosed proxy card (which is unique to each Essential shareholder of record to ensure all voting instructions are genuine and to prevent duplicate voting). If a holder of record chooses to submit its proxy by telephone or via the
Internet, the proxy must be received by 11:59 p.m., Eastern time on February 9, 2026 in order to be counted at the Essential special meeting.

To
vote during the live webcast, follow the instructions available on the Essential special meeting website at www.virtualshareholdermeeting.com/WTRG2026SM. The Essential special meeting will be held exclusively online via live webcast. To be
admitted to the live webcast, holders of record must provide their 16-digit control number. It is recommended that holders of record submit their vote by proxy prior to the date of the Essential special
meeting even if they plan to attend the meeting virtually via the Internet.

Beneficial Holders (in “Street Name”)

If you hold shares of Essential common stock in “street name,” you will receive a voting instruction form from your intermediary. The form will
explain how to direct the voting of your shares through the intermediary, which may include the ability to provide voting instructions via the Internet or by telephone.

If your shares of Essential common stock are held in “street name” and you want to vote on the merger agreement proposal, the merger-related
compensation proposal, or the Essential adjournment proposal, you MUST indicate how you wish your 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.

If you hold shares of Essential common stock in “street name” and wish to vote your shares virtually at the Essential
special meeting, you may vote online during the meeting as an authenticated shareholder with a 16-digit control number by visiting www.virtualshareholdermeeting.com/WTRG2026SM, entering your 16-digit control number
