Consolidated Results

For the three and nine months ended September 30, 2024, earnings per share were $1.80 and $4.17, respectively, compared to $1.66 and $4.03 per share in the same periods in 2023. Results include the increased revenues from implementation of new rates in the Regulated Businesses from capital and acquisition investments. Results also reflect increased production and employee-related costs, increased depreciation and higher financing costs used to fund the current capital investment plan. Results for the three and nine months ended September 30, 2024, reflect the net favorable impact of warmer, drier weather compared to normal, estimated at $0.04 and $0.07 per share, respectively. Results for the three and nine months ended September 30, 2023, reflect the net favorable impact of weather compared to normal, estimated at $0.04 and $0.11 per share, respectively. Results for the three and nine months ended September 30, 2024, include incremental interest income of $0.03 and $0.07 per share, respectively, resulting from the early 2024 amendment to the secured seller note from the sale of the former HOS business.

The company is on track to modestly exceed its original capital investment plan for the year with investments of $2.0 billion in the first nine months of 2024, including $1.9 billion for infrastructure improvements and replacements, primarily in the Regulated Businesses, and $119 million for acquisitions.

Regulated Businesses

In the third quarter of 2024, the Regulated Businesses’ net income was $356 million, compared to $331 million for the same period in 2023. For the first nine months of 2024, the Regulated Businesses’ net income was $815 million, compared to $783 million for the same period in 2023.

 

PRESS RELEASE		2		www.amwater.com

---

Operating revenues increased $124 million and $244 million for the three and nine months ended September 30, 2024, respectively, as compared to the same periods in 2023. The increase in operating revenues was primarily a result of authorized revenue increases from completed general rate cases and infrastructure proceedings for the recovery of incremental capital and acquisition investments.

Since January 1, 2024, the company has been authorized additional annualized revenues of $346 million with $256 million from general rate cases and $90 million from infrastructure surcharges. The company has general rate cases in progress in seven jurisdictions and has filed for infrastructure surcharges in three jurisdictions, reflecting a total annualized revenue request of $375 million. Most of the additional authorized revenues in 2024 had effective dates in the second or third quarter of this year.

Operating expenses were higher by $63 million and $139 million for the three and nine months ended September 30, 2024, respectively, as compared to the same periods in 2023. Operating expenses were higher primarily due to an increase in employee related costs, as well as general taxes associated with increased capital investment, and increased production costs, which include higher purchased water cost and usage. Operating expenses also include depreciation expense, which was higher by $22 million and $54 million in the same periods, respectively, due to the growing capital investment.

Interest expense was higher by $15 million and $37 million for the three and nine months ended September 30, 2024, respectively, as compared to the same periods in 2023, to fund capital investments.

Dividends

On October 29, 2024, the company’s Board of Directors declared a quarterly cash dividend payment of $0.7650 per share, payable on December 3, 2024, to shareholders of record as of November 12, 2024.

Non-GAAP Financial Measures

This press release includes a presentation of American Water’s 2024 and 2025 earnings guidance ranges excluding the $0.10 per share of incremental interest income to be recognized from the amended HOS note. This presentation constitutes a “non-GAAP financial measure” under SEC rules. It is derived from American Water’s consolidated financial information but is not presented in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”). This presentation supplements American Water’s GAAP disclosures and should be considered in addition to, and not in substitution of, measures of financial performance prepared in accordance with GAAP. Management believes this presentation is useful to American Water’s investors because it excludes an item not reflective of its ongoing operating results and the presentation will allow investors to understand better the operating performance of American Water’s regulated businesses. Although management will use this presentation internally to evaluate American Water’s results of operations and to facilitate a meaningful year-to-year comparison thereof, management does not intend this presentation to represent future results as defined by GAAP, and investors should not consider them as such. In addition, this presentation of guidance may not be comparable to similar presentations by other companies, and, accordingly, it may have significant limitations in its use.

2024 and 2025 Earnings Guidance (Non-GAAP) This presentation includes a description of American Water’s 2024 and 2025 earnings guidance ranges, and its expected 2024 dividend payout ratio, excluding the incremental $0.10 per share of interest to be recognized from the amended HOS seller note. This information would constitute “non-GAAP financial measures” under SEC rules. They are derived from American Water’s consolidated financial information but are not presented in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”). This information supplements American Water’s GAAP disclosures and should be considered in addition to, and not in substitution of, measures of financial performance prepared in accordance with GAAP. Management believes this information is useful to American Water’s investors because it excludes an item not reflective of its ongoing operating results and the presentation will allow investors to understand better the operating performance of American Water’s regulated businesses. Although management will use this information internally to evaluate American Water’s results of operations and to facilitate a meaningful year-to-year comparison thereof, management does not intend this information to represent future results as defined by GAAP, and investors should not consider it as such. In addition, this information may not be comparable to similar presentations by other companies, and, accordingly, it may have significant limitations in its use. 26

U.S. EPA PFAS Rule Announced on April 10, 2024 Largely unchanged from proposed rule Final Federal PFAS Rule Recap Ø Drinking water limits of 4.0 parts per trillion (ppt) for PFOA and PFOS unchanged vs. proposed rule • Limits set for three additional PFAS Ø Five years to comply versus three years in the proposed rule (2029 versus 2027) Ø U.S. EPA designated PFOA and PFOS as hazardous substances under CERCLA through a separate rulemaking in April. The Company is actively advocating and supporting bipartisan legislation that would provide PFAS liability protections under CERCLA for water and wastewater systems, as passive receivers of PFAS. Ø American Water’s estimates ~$1B of capital and up to ~$50M annually for operating expenses * *Includes PFAS treatment PFAS Litigation Recap Ø American Water is a party to the Multi-District Litigation (MDL) lawsuit against several PFAS manufacturers. Ø In Dec. 2023, we decided to remain a party to two settlements, which we believe is the best path for our customers. • In Feb. and Mar. 2024, the MDL court approved settlements with DuPont and 3M, respectively; the amount of proceeds to be received from each settlement is pending. 32

Lead Service Lines Remain in Focus Review of U.S. EPA’s Lead and Copper Rule Improvements Rule S On October 8, 2024, the United States Environmental Protection Agency (EPA) announced final Lead and Copper Rule Improvements (LCRI). S The LCRI includes requirements related to (1) achieving lead replacement by the end of 2037, 10 years from the Compliance Date; (2) locating legacy lead pipes; (3) improving tap water sampling; (4) lowering the lead action level; and (5) strengthening protections to reduce exposure. S American Water consistently meets water quality standards related to the lead and copper rules across our footprint and believes removing the risk of lead service lines over time is the right thing to do for the health and safety of our customers. S Developing an accurate, comprehensive inventory, including identifying the material of service lines where the material is currently unknown, is an important next step in eliminating lead service lines. S We believe all stakeholders must understand the costs associated with the proposed improvements to the Lead and Copper Rule and that the EPA estimates are likely understated. The cost to identify the material of all unknown service lines and replace all lead service lines and galvanized lines, where needed, by 2037 will require significant investment for all water systems. S American Water is in the process of reviewing the specific requirements of the LCRI to determine capital expenditures and operating costs. Capital expenditures and operating costs associated with compliance with federal water quality regulations have been traditionally recognized by PUCs as appropriate for inclusion in establishing rates. 33
