American Water Works Company (AWK) has put a spotlight on long-term infrastructure spending by releasing a Wastewater Solutions white paper and outlining about US$48b in planned capital improvements over the next decade.

Despite the Wastewater Solutions white paper and the roughly US$48b capital plan, American Water Works Company’s recent momentum has been mixed, with a 4.0% 1 month share price gain contrasting with a 6.1% decline in 1 year total shareholder return.

American Water Works Company shares have firmed over the past month but are still down over 1 and 3 years, so does that recent uptick offer a fresh entry point or mainly compress the upside left on the table?

Most Popular Narrative: 3.7% Undervalued

American Water Works Company is priced at $130.55 against a narrative fair value of $135.55, which frames the recent share price weakness as leaving some headroom, but that view rests on a detailed long term earnings and regulation story.

Persistent population growth and urbanization across key U.S. states are fueling organic customer additions (for example, 2% customer growth target and multiple acquisitions adding approximately 87,000 connections). This underpins long-term revenue growth as American Water expands its service footprint and taps into rising water demand.

Heightened regulatory and societal focus on water quality and infrastructure modernization is accelerating rate case approvals and driving significant capital investment (for example, $3.3 billion capital spend in 2025 and requests for $111 million cumulative rate increases in CA by 2029). These factors enable predictable, above-inflation rate increases and support sustainable earnings expansion.

Curious what kind of revenue path, margin lift, and future earnings multiple need to line up for that fair value to hold? The most followed narrative spells out a detailed growth runway, a specific profitability step up, and a valuation reset that together underpin the current $135.55 figure, but the exact mix of assumptions might surprise you.

Result: Fair Value of $135.55 (UNDERVALUED)

However, the American Water Works Company story could be knocked off course if higher financing costs squeeze returns or if key state regulators grant less supportive rate outcomes.

Another View: What American Water Works Company’s P/E Is Saying

The fair value narrative suggests American Water Works Company has some upside, but its 23.1x P/E is slightly above a fair ratio of 22.3x and well above the global water utilities average of 15.1x, even if it sits close to U.S. peers at 23.4x. That mix of mild premium and globally richer pricing raises a simple question for you as an investor: is this a safety premium worth paying, or a signal to be more price sensitive?
