**Public Service Commission of Maryland (the "MDPSC") Approval of Settlement in Maryland-American Water Company ("Maryland American Water") General Rate Case**

On February 26, 2026, the MDPSC issued an order (the "Order") approving the joint settlement of the general rate case filed on August 1, 2025 by Maryland American Water, a wholly owned subsidiary of American Water Works Company, Inc. (the "Company"). A joint stipulation and settlement agreement by and among Maryland American Water, the Office of People's Counsel, and the Staff of the MDPSC was filed with the MDPSC on January 22, 2026. The Order approves a consolidated annualized increase in water revenues of approximately $2 million, with approximately $1 million of the increase to be included in rates effective concurrently with the date of the Order, and the remainder effective January 1, 2027. Maryland American Water's view of its return on equity ("ROE"), common equity ratio and debt ratio (each of which is based on the information included in the Order and the joint stipulation and settlement agreement, but was not disclosed therein), is 9.75%, 52.32% and 47.68%, respectively. The annualized incremental revenue is driven primarily by approximately $22 million of capital investments completed by Maryland American Water since its last general rate case approval in 2019.

A copy of the press release issued by Maryland American Water on March 2, 2026 has been filed as <u>[Exhibit 99.1](exhibit991-pressreleaseofm.htm)</u> hereto and is incorporated herein by reference.

**Maryland American Water Granted New Rates by Maryland Public Service Commission** 

*Increase Supports $22 Million in Completed Infrastructure Investments;*

*First Rate Adjustment Since 2019*

**Bel Air, Md. (March 2, 2026)** –The Maryland Public Service Commission (PSC) has approved a settlement for new water rates for Maryland American Water. The approved rates represent a total annualized revenue increase of approximately $2 million.

The company's rate request was filed on August 1, 2025, and supports approximately $22 million in completed capital and infrastructure investments in treatment system and distribution improvements since its last approved rate request in 2019.

"We are committed to making the necessary investments to continue the high-quality service our customers expect and deserve and ensure compliance with state and federal regulations," **said Laura Runkle, President, Maryland American Water**. "Our capital planning approach to consistent and efficient investment helps improve water service reliability for the 24,000 people we serve."

The new rates will be implemented over two years. Effective February 26, 2026, residential customers in the Town of Bel Air using 4,000 gallons per month will see their average bill increase by approximately $10 per month. On January 1, 2027, their bill will increase by another $10 per month. In the Severn District, residential customers previously billed a quarterly flat fee will transition to a monthly flat fee, which will increase by approximately $1.50 per month effective February 26, 2026. This is the first rate adjustment since 2019.

Maryland American Water also supports various important customer affordability programs by providing customers with bill paying assistance programs, payment arrangements and budget billing options, all available on the customer MyWater portal at marylandamwater.com. Income-eligible customers may also apply for assistance through the company's H2O Help to Others program, administered by Dollar Energy Fund. More information can be found at marylandamwater.com under "Customer Service & Billing" and "Customer Assistance Programs."

Customers will receive information about the new rates in their next Maryland American Water bill. Information will also be available on the company's website at www.marylandamwater.com under Customer Service & Billing, your Water Rates.
