American Water Works Company, Inc. (AWK) Income Statement

Revenue growth has been consistently positive, ranging from 4.7% to 16.4% year-over-year over the past ten quarters, indicating a durable trajectory supported by ongoing capital investment in regulated water infrastructure. The growth is not weather-dependent but reflects successful rate case outcomes and customer growth, which are typical for regulated water utilities. This suggests that AWK's revenue expansion is likely to continue as long as the regulatory environment remains constructive and capital spending remains elevated.

The operating margin has been stable and high, ranging from 31.9% to 42.3% over the period, indicating that AWK is effectively recovering its costs and earning a return close to what regulators allow. The slight improvement in margins may reflect efficient cost management and timely rate adjustments, which are critical in a regulated environment. However, the gap between authorized and earned ROE could widen if regulatory lag increases, so investors should monitor rate case outcomes and the pace of capital deployment.

The increase in depreciation and amortization reflects the growing asset base, which is a positive sign for rate base growth. Since water utilities typically have mechanisms to recover operating costs, including purchased water and treatment chemicals, the reported revenue growth is not purely organic but includes pass-through costs. This implies that AWK's earnings power is protected from cost inflation, but it also means that revenue growth may overstate the underlying earnings growth if cost recovery is not fully timely.

The increase in D&A is a direct result of the growing asset base, which is the primary driver of rate base growth and, consequently, earnings growth. The fact that EPS has grown at a faster pace than D&A suggests that AWK is earning a return on new investments that exceeds the incremental depreciation expense, which is a positive sign for shareholders. However, the timing of rate base inclusion can create regulatory lag, so the full earnings benefit of CAPEX may not be realized until rates are adjusted, which warrants monitoring of rate case filings.
