AMERICAN WATER REPORTS THIRD QUARTER 2008 RESULTS

• Operating revenues increase 6.2 percent to $672.2 million

• Net income of $88.2 million or $0.55 per share for third quarter 2008

• Excluding goodwill impairment charge(a non-GAAP financial measure), approximately 11 percent growth over third quarter 2007 net income of $79.5 million

• Annualized general rate increases of approximately $27.0 million

VOORHEES, N.J., November 5, 2008 – American Water Works Company, Inc. (NYSE: AWK), the largest investor-owned U.S. water and wastewater utility company, today reported results for the third quarter ended September 30, 2008.

For the quarter, the company reported operating revenues of $672.2 million, a 6.2 percent increase or $39.1 million over the same period in 2007. Net income in the third quarter was $88.2 million, or $0.55 per basic and diluted common share, compared with a loss of $160.1 million or $1.00 per basic and diluted common share, in the third quarter of 2007. Excluding the goodwill impairment charge, the third quarter 2007 net income would have been $79.5 million, showing approximately 11 percent growth quarter over quarter. The increase in net income was due primarily to higher revenues in its Regulated Business.

“We continue to make progress in our regulatory filings,” said Don Correll, president and CEO of American Water. “The increase in revenues, despite the high rainfall our Midwest operations have experienced, reflects our commitment to prudently invest in infrastructure and our ability to achieve an appropriate rate of return on those investments.”

For the third quarter, the company received authorizations for additional annualized revenues from general rate case activity of approximately $27.0 million, which brings the total for the first nine months of 2008 to $73.9 million. As of September 30, 2008, the company has general rate cases awaiting final order in nine additional states that would provide $267.6 million of additional revenues, if approved as filed. The extent to which these rate increase requests will be granted by the applicable regulatory agencies will vary.

    AMERICAN WATER REPORTS THIRD QUARTER 2008 RESULTS

The increase in operating revenues from the company’s Regulated Business of $31.6 million, or 5.5 percent increase over the same period in 2007 was achieved even with the Midwest experiencing some of the wettest weather on record. For the company as a whole, primarily due to weather, total volume of water sold decreased 4.8 percent for the quarter ended September 30, 2008, to 122.3 billion gallons, from 128.5 billion gallons for the same period in 2007, resulting in an estimated reduction of $11.4 million in revenues, approximately $5.8 million in net income, or $.04 per basic and diluted common share.

The company’s Non-regulated Businesses’ revenues increased by $7.5 million or 11.3 percent for the third quarter, compared to the same period in 2007. The increase was primarily attributable to higher revenues in the Homeowner Services Group and the Contract Operations Group.

“We had some exciting growth news during the quarter on the non-regulated side of the business,” added Correll. “Our Military Services Group was awarded contracts for the water distribution systems and wastewater collection systems at Fort Hood Army Installation in Texas and at Fort Polk Army Installation in Louisiana. The awards of these contracts are estimated at approximately $329.0 million and $348.0 million, respectively, over a 50-year period and complement our business capabilities.”

Operating expenses for the three month period ending September 30, 2008 totaled $460.4 million. Adjusting for the 2007 third quarter goodwill impairment charge of $243.3 million, operating expenses in the third quarter 2008 increased $16.0 million from the third quarter 2007, primarily due to employee-related costs. The Non-regulated Business segment’s increased expenses of $3.5 million correspond with its increased revenues.

Non-recurring Sarbanes-Oxley readiness and other divestiture-related expenses totaled $1.5 million in the third quarter, decreasing by $11.1 million from the prior year period, resulting in approximately $6.7 million in added net income, or $.04 per basic and diluted common share.

During the third quarter, the company’s Board of Directors declared its second consecutive quarterly cash dividend of $0.20 per common share.

Net cash provided by operating activities, for the nine months ending September 30, 2008, increased approximately $63.0 million or 19.1 percent to $392.9 million, from $329.9 million in the prior year period, showing our continued focus on cash management.

Cash outflows related to construction expenditures, for the nine months ending September 30, 2008, increased $207.4 million to approximately $714.6 million from $507.2 million in the prior year period, as a result of continued prudent investment in regulated utility plant projects. A major project underway is the construction of a 20 million-gallon-a-day water treatment plant and a 31-mile water transmission line in Kentucky. This project will address a long-standing water supply deficit in central Kentucky.
