American Water Works is the largest US regulated water and wastewater utility.
AWK vs DUK: how the two businesses compare
American Water Works (AWK) and Duke Energy (DUK) do not both have comparable annual revenue in the SEC XBRL snapshot, so this comparison rests on business descriptions, classifications, and filings. The SEC places them in related industries (Water Supply; Electric & Other Services Combined), and both map to the Rates & central banks research theme.
Figures come from each company's own SEC filings. This page compares the businesses; it is not a price target or a verdict.

Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. Both fiscal years end December 31, so annual reports line up, but check segment definitions before comparing growth or margins.
The current verified House and Senate snapshot contains 10 matched transaction rows for AWK and 13 matched transaction rows for DUK. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you
This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.
A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.
