| • |     | This transaction builds on the proud heritages of both our companies, each going back almost 140 years. |

| • |     | American Water and Essential are two like-minded organizations, who share a common purpose. |

| • |     | Together, we will remain committed to safety, sustainable growth, operational excellence and superior customer                                                            
 experience. We both recognize the valuable contributions that our employees make to our success, and are committed to maintaining our recognition as a top-tier employer. |

| • |     | Looking ahead, we expect the combined company to reflect the capabilities and talent of both organizations. |

| • |     | In addition, we intend to carry forward best practices from both companies in corporate social responsibilities. 
 We will protect human health and the environment and make communities stronger.                                  |

Chris Franklin

| • |     | You know, having been with Essential for nearly 35 years, I can safely say that the company is part of who I am. 
 And I couldn’t agree more that the values Essential possesses are closely aligned with American Water.           |

| • |     | I’m looking forward to working closely with John to create one of the strongest, most innovative and 
 customer-focused utilities in the United States.                                                     |

| • |     | While our merger announcement is a significant milestone, it is still just the first step in bringing our 
 companies together.                                                                                       |

| • |     | We expect the transaction to be completed by the end of the first quarter of 2027, following the satisfaction of 
 closing conditions and approvals.                                                                                |

| • |     | Until that time, we will operate as separate, independent organizations over the coming months, and we will build     
 an integration planning team with representatives from both companies to address how we bring our companies together. |

John Griffith

| • |     | Thank you, Chris. Upon closing of the merger, I will serve as President and CEO of the combined company and Chris        
 will serve as Executive Vice Chair of the Board of Directors as well as executive sponsor of the integration task force. |

| • |     | Additionally, the combined company will be headquartered in Camden, New Jersey, and Essential Utilities’ 
 Bryn Mawr and Pittsburgh offices will each continue to maintain a strong operational presence long term. |

| • |     | Given the complementary nature of our assets and culture
