American Water’s Corporate Credit Rating of ‘A’, Its Stable Outlook, and Its A-1 Short-Term Credit Rating Receives Affirmation from Standard & Poor’s

CAMDEN, N.J.–(BUSINESS WIRE)–American Water (NYSE: AWK), the largest publicly traded U.S. water and
wastewater utility company, announced today that Standard & Poor’s (S&P)
reported on June 7, 2019, it had affirmed the corporate credit rating of
‘A’, its stable outlook and its A-1 short-term credit rating, on
American Water Works Company, Inc. and its American Water Capital Corp.
finance subsidiary.

S&P stated its rationale for the affirmation as due primarily to
American Water’s key strengths including: the vast majority of American
Water’s cash flows are derived from lower-risk, rate-regulated
water-utility operations; the benefits from significant geographic and
regulatory diversity as the largest investor-owned water-utility company
in the U.S.; and the company’s effective management of regulatory risk
as demonstrated by its implementation of numerous constructive
regulatory mechanisms.

“We are pleased with S&P’s decision, which reflects the advantage of our
company’s geographic diversity and our continuous efforts to maintain a
strong balance sheet,” said Linda G. Sullivan, executive vice president
and chief financial officer of American Water. “Our efforts to maintain
a strong balance sheet benefit the 15 million people who depend on us to
provide clean, safe, reliable and affordable water services to them
every day. Having greater access to capital at lower debt costs enhances
our ability to make needed investments in our water and wastewater
systems while balancing the impact it has on the customers we serve.”

A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by
the rating agency. Each rating should be evaluated independently of any
other rating. Further risks and uncertainties with respect to these
ratings are described in American Water’s Form 10-K for the year ended
December 31, 2018, as filed with the Securities and Exchange Commission
on February 19, 2019.
