Nike Inc. (NYSE:NKE)

The analysis of the return on invested capital (ROIC) reveals a consistent downward trajectory over the six-year period from May 31, 2021, to May 31, 2026. The ROIC peaked at 26.81% in 2021 and experienced a steady decline, accelerating sharply after May 31, 2024, to reach a low of 14.20% by May 31, 2026.

Net Operating Profit After Taxes (NOPAT)

NOPAT remained relatively stable between 2021 and 2024, fluctuating within a range of US$ 5,012 million to US$ 5,616 million. However, a significant contraction occurred in 2025, where NOPAT fell to US$ 2,921 million, representing a decrease of approximately 43% from the previous year. A marginal recovery is observed in 2026, with NOPAT rising slightly to US$ 3,060 million.

Invested Capital

The capital base exhibited moderate volatility, generally maintaining a range between US$ 19,851 million and US$ 22,088 million. While invested capital peaked in 2024, it saw a reduction in 2025 before increasing again to US$ 21,555 million in 2026. The relative stability of the invested capital suggests that the decline in ROIC was not driven by excessive capital expansion, but rather by diminished earnings efficiency.

ROIC Performance Drivers

The compression of ROIC from 26.81% to 14.20% is primarily attributable to the erosion of NOPAT. The most acute decline occurred between 2024 and 2025, where ROIC dropped from 23.30% to 14.72%. This indicates a substantial reduction in the company's ability to generate operating profits from its deployed capital during the latter part of the observed period.

A sustained decline in the Return on Invested Capital (ROIC) is observed over the analyzed six-year period. Starting at 26.81% in May 2021, the ROIC experienced a gradual reduction through May 2024, followed by a sharp contraction to 14.72% in May 2025 and a further slight decrease to 14.20% by May 2026. This downward trajectory indicates a diminishing efficiency in generating returns from the capital invested in the business.

Operating Profit Margin (OPM)

The erosion of the operating profit margin is the primary driver of the decline in ROIC. The OPM decreased from 15.72% in 2021 to 8.54% in 2026. A critical inflection point occurred between 2024 and 2025, where the margin dropped significantly from 12.90% to 8.36%, suggesting a substantial increase in operating expenses or a compression in pricing power during that interval.

Turnover of Capital (TO)

Capital turnover exhibited more volatility but remained relatively stable compared to the profit margins. The ratio peaked at 2.52 in May 2023, providing a temporary buffer against declining margins. However, by May 2026, the turnover ratio returned to 2.15, near its 2021 level of 2.13. This indicates that while asset utilization improved mid-period, it was insufficient to offset the long-term deterioration in profitability.

Effective Cash Tax Rate Impact

The tax component, represented by the value of 1 minus the effective cash tax rate, showed a gradual downward trend from 80.14% in 2021 to 77.26% in 2026. While this represents a slight increase in the effective tax burden over time, its impact on the overall ROIC is marginal compared to the significant shifts in operating margins.

The decomposition of the return metrics reveals that the overall decline in capital efficiency is almost exclusively attributable to the compression of operating margins. The relative stability of capital turnover and the tax rate suggests that the business's challenges are rooted in operational profitability rather than asset mismanagement or tax inefficiencies.

The analysis of operational performance over the observed period reveals a significant contraction in profitability margins despite an initial phase of revenue growth. A clear divergence is evident between top-line expansion and the ability to maintain operating efficiency, culminating in a sharp decline in profitability toward the end of the period.

Revenue Trends

Revenues experienced a growth phase between 2021 and 2024, rising from 44,538 million to a peak of 51,362 million. This upward trajectory was reversed in 2025, with revenues falling to 46,309 million and remaining nearly flat through 2026 at 46,398 million.

Net Operating Profit Before Taxes (NOPBT)

NOPBT exhibited a general downward trend with a brief period of volatility. After starting at 7,001 million in 2021, operating profit declined to 6,275 million by 2023. A partial recovery to 6,627 million was noted in 2024, followed by a severe contraction to 3,873 million in 2025 and a marginal increase to 3,961 million in 2026.

Operating Profit Margin (OPM) Performance

The OPM shows a persistent decline from 15.72% in 2021 to 8.54% in 2026. The margin compression was most acute between 2024 and 2025, where the ratio dropped from 12.90% to 8.36%. This indicates that operating expenses grew at a faster rate than revenues, or that pricing power diminished significantly during this timeframe.

Profitability Stability

The data suggests a stabilization at a lower performance baseline in the final two years. Both the OPM and NOPBT show minimal variance between 2025 and 2026, indicating that the company has entered a phase of diminished operational efficiency compared to the 2021-2022 levels.

The efficiency of capital utilization exhibits a cyclical trend, characterized by an initial improvement in asset productivity followed by a period of contraction. The turnover of capital indicates a peak in operational efficiency during the middle of the observed period, which subsequently declined as revenue growth stalled and capital requirements fluctuated.

Revenue Trends

A growth trajectory is observed from 2021 to 2024, with revenues increasing from 44,538 million US$ to a peak of 51,362 million US$. This expansion was followed by a notable contraction in 2025 to 46,309 million US$, with a period of relative stagnation occurring between 2025 and 2026.

Invested Capital Dynamics

Invested capital remained relatively stable, fluctuating within a range of 19,851 million US$ to 22,088 million US$. A temporary reduction in capital was noted in 2023 and 2025, while an increase was observed in 2024 and 2026, suggesting periodic adjustments in the company's asset base.

Turnover of Capital Analysis

The turnover ratio improved from 2.13 in 2021 to a peak of 2.52 in 2023, indicating a period of optimal capital efficiency where revenue growth outpaced the growth of invested capital. However, a downward trend followed, with the ratio decreasing to 2.33 in 2024 and 2025, and further declining to 2.15 by 2026. This regression suggests a diminishing ability to generate sales from the invested capital base, primarily driven by the revenue decline observed in the latter years of the period.

The financial data reveals a diverging relationship between operating profitability and the effective cash tax rate over the period from May 31, 2021, to May 31, 2026. While absolute profitability and tax expenditures experienced significant volatility, the percentage of profit allocated to cash taxes generally trended upward until 2025.

Net Operating Profit Before Taxes (NOPBT) Trends

NOPBT remained relatively stable between 2021 and 2022, followed by a decline in 2023 and a partial recovery in 2024. A sharp contraction is observed in 2025, where profit fell to 3,873 million US$, representing a significant decrease from the 6,627 million US$ recorded in 2024. A marginal recovery is noted by May 31, 2026, with NOPBT rising slightly to 3,961 million US$.

Cash Operating Tax Expenditures

Cash taxes followed a trajectory similar to NOPBT for the first four years, peaking in 2024 at 1,482 million US$. Consistent with the drop in operating profit, cash tax payments decreased substantially in 2025 to 951 million US$ and continued to decline slightly to 901 million US$ in 2026.

Effective Cash Tax Rate (CTR) Analysis

The effective cash tax rate exhibited a general increase despite the fluctuations in NOPBT. After a low of 18.95% in 2022, the CTR rose steadily, reaching its peak of 24.57% in 2025. This indicates that during the period of steepest profit decline in 2025, the proportion of operating profit paid in cash taxes actually increased. The rate moderated slightly to 22.74% by May 31, 2026.

In summary, the period is characterized by a contraction in operating profitability and a corresponding decrease in absolute tax payments, yet these were offset by a rising effective cash tax rate. The increase in the CTR during 2024 and 2025 suggests a reduced capacity to utilize tax shields or a change in the jurisdictional tax mix, which increased the tax burden relative to operating earnings.
