Nike Inc. (NYSE:NKE)

The profitability ratios demonstrate a complex pattern of performance over the analyzed period. Initially, the metrics exhibited growth, peaking around the end of fiscal year 2021, before experiencing a gradual decline through fiscal year 2025. This suggests a period of strong performance followed by increasing pressure on profitability.

Gross Profit Margin

The gross profit margin generally increased from 43.15% in August 2020 to a high of 46.20% in February 2022. However, a consistent downward trend is then observed, falling to 40.81% in February 2026. This indicates increasing costs of goods sold relative to revenue over the latter portion of the period.

Operating Profit Margin

The operating profit margin shows a more pronounced increase initially, rising from 8.94% to a peak of 15.79% in August 2021. Subsequently, it declined steadily, reaching 6.03% in February 2026. This suggests that while revenue growth was initially strong, operating expenses began to outpace revenue increases, impacting overall operational efficiency.

Net Profit Margin

Mirroring the trend in operating profit margin, the net profit margin increased significantly from 7.20% to 13.32% by November 2021. A consistent decline then follows, ending at 4.84% in February 2026. This indicates a weakening ability to translate revenue into net income, likely due to a combination of increased costs and potentially higher tax burdens or non-operating expenses.

Return on Equity (ROE)

ROE experienced substantial volatility. It rose from 29.16% to a peak of 44.86% in May 2021, then fluctuated before declining to 15.97% in February 2026. This suggests that the company’s ability to generate profits from shareholder investments has diminished over time, potentially due to decreasing net income and/or changes in equity structure.

Return on Assets (ROA)

ROA followed a similar trajectory to ROE, increasing from 8.09% to 16.04% in August 2021, and then decreasing to 6.07% in February 2026. This indicates a reduced efficiency in utilizing assets to generate profits. The decline in ROA aligns with the observed decreases in profitability margins.

In summary, the analyzed period demonstrates a shift from a period of robust profitability growth to one of consistent decline. The decreasing trends in all five ratios suggest increasing challenges in maintaining profitability and efficiently utilizing resources. Further investigation into the underlying drivers of these trends, such as cost structures, competitive pressures, and operational efficiencies, would be necessary to formulate effective strategies for improvement.

The gross profit margin exhibited a generally upward trend from August 2020 through February 2022, followed by a period of fluctuation and a subsequent decline through February 2026. Initial values hovered around 43%, increasing to a peak of 46.20% in February 2022 before entering a period of volatility. The most recent periods show a consistent downward trend, ending at 40.81% in February 2026.

Overall Trend

From the initial period observed, the gross profit margin generally increased, suggesting improved efficiency in production or sourcing, or a shift towards higher-margin products. However, this positive trend reversed in the latter half of the observed period, indicating potential pressures on cost of goods sold or pricing strategies.

Peak Performance

The highest gross profit margin was recorded in February 2022 at 46.20%. This peak coincided with a period of relatively stable revenue, suggesting effective cost management during that quarter. The preceding quarters also showed strong performance, with margins exceeding 45% from August 2021 onwards.

Recent Decline

A clear downward trend in the gross profit margin is evident from May 2022 through February 2026. The margin decreased from 45.98% in May 2022 to 40.81% in February 2026. This decline may be attributable to increased input costs, competitive pricing pressures, or a change in the product mix towards lower-margin items. The rate of decline appears to be accelerating in the most recent periods.

Quarterly Fluctuations

While the overall trend is discernible, quarterly fluctuations exist. For example, a slight dip was observed in November 2020, followed by recovery. Similar, smaller fluctuations occurred throughout the period, suggesting sensitivity to seasonal factors or short-term market conditions. However, these fluctuations were less pronounced than the overall long-term trends.

Correlation with Revenues

The gross profit margin does not appear to have a strong, consistent correlation with revenue. Periods of high revenue, such as May 2021 and May 2022, do not necessarily correspond to the highest gross profit margins. This suggests that revenue growth is not automatically translating into improved profitability, and that cost management is a critical factor.

The operating profit margin exhibited considerable fluctuation over the analyzed period, spanning from August 2020 to November 2025. Initially, the margin demonstrated an upward trajectory, peaking in the May 2021 period, before entering a phase of gradual decline. A subsequent period of stabilization and minor volatility followed, ultimately culminating in a noticeable downward trend towards the end of the observation window.

Initial Growth Phase (Aug 31, 2020 – May 31, 2021)

The operating profit margin increased from 8.94% in August 2020 to a high of 15.58% in May 2021. This represents a substantial improvement in profitability during this timeframe, potentially driven by increased revenue and effective cost management. The increase from 9.67% in November 2020 to 15.58% in May 2021 is particularly noteworthy.

Stabilization and Moderate Decline (Aug 31, 2021 – May 31, 2022)

Following the peak in May 2021, the operating profit margin experienced a period of relative stability, fluctuating between 15.48% and 15.79% through November 2021. A gradual decline then commenced, decreasing to 14.29% by May 2022. While still representing a healthy margin, this signals a potential shift in underlying profitability factors.

Accelerated Downward Trend (Aug 31, 2022 – Nov 30, 2025)

From August 2022 onwards, a more pronounced downward trend became evident. The operating profit margin decreased from 13.25% to 7.99% in February 2025, and further declined to 6.03% in November 2025. This suggests increasing cost pressures, declining pricing power, or a combination of both. The most significant drop occurred between May 2025 (6.54%) and November 2025 (6.03%).

Revenue Correlation

While not directly calculated here, a review of the revenue figures suggests a complex relationship with the operating profit margin. Revenue increased significantly between August 2020 and May 2021, coinciding with the margin expansion. However, revenue fluctuations in subsequent periods do not consistently correlate with margin changes, indicating that factors beyond revenue volume are influencing profitability. For example, revenue increased from February 2024 to May 2024, but the operating profit margin decreased during the same period.

In conclusion, the operating profit margin initially demonstrated strong growth, followed by a period of stabilization and ultimately a concerning decline. The recent trend warrants further investigation to identify the root causes and implement appropriate corrective measures.

The net profit margin exhibited considerable fluctuation over the observed period. Initially, the metric demonstrated a modest increase from 7.20% in August 2020 to 7.39% in November 2020. A more substantial rise followed, peaking at 13.17% in August 2021, indicating improved profitability during that time. This positive trend continued into November 2021, reaching 13.32% before experiencing a slight decline.

Overall Trend

From February 2022 through May 2024, the net profit margin generally trended downwards, albeit with some intermittent increases. The highest value within this period was 12.94% in May 2022, while the lowest was 9.43% in November 2024. This suggests increasing cost pressures or decreasing pricing power during this timeframe.

Recent Performance

A significant decrease in net profit margin is evident in the latter portion of the period. The metric fell from 11.10% in February 2024 to 6.95% in November 2024, and continued to decline, reaching 4.84% in February 2026. This sharp downturn warrants further investigation into potential factors such as increased operating expenses, reduced sales volume, or shifts in product mix.

The period between August 2020 and November 2021 shows a clear improvement in profitability, while the subsequent period demonstrates a concerning erosion of margins. The most recent quarterly values indicate a substantial contraction in profitability, potentially signaling emerging challenges for the company.

Peak and Trough

The peak net profit margin was 13.32% recorded in November 2021. Conversely, the lowest net profit margin observed was 4.84% in February 2026, representing a substantial difference from the peak value.

The volatility in the net profit margin suggests the company’s earnings are sensitive to changes in revenue and/or cost structures. Continued monitoring of this metric, alongside related financial indicators, is recommended to understand the underlying drivers of these fluctuations.

The Return on Equity (ROE) exhibited considerable fluctuation over the observed period, spanning from August 2020 to November 2025. Initially, the ROE demonstrated a generally positive trend, peaking in the May 2021 period, before entering a phase of gradual decline and increased volatility.

Initial Growth & Peak (Aug 2020 – May 2021)

The ROE began at 29.16% in August 2020 and generally increased, reaching a high of 44.86% in May 2021. This period suggests improving profitability relative to shareholder equity. The increase was not consistent, with some quarterly dips, but the overall trajectory was upward.

Decline & Stabilization (May 2021 – Feb 2023)

Following the peak, the ROE experienced a decline, though it remained relatively stable between 36.20% and 42.41% for several quarters. This suggests that while profitability remained strong, the rate of return on equity was decreasing. The period from November 2021 to February 2023 showed a more consistent range, fluctuating between 37.70% and 41.34%.

Downward Trend & Volatility (Feb 2023 – Nov 2025)

From February 2023 onwards, a more pronounced downward trend became evident. The ROE decreased from 37.70% to 24.36% by February 2025, and further to 21.50% in May 2025. This decline accelerated in the final observed period, reaching 15.97% in November 2025. This period is characterized by increased volatility, indicating potential challenges in maintaining profitability relative to equity.

Net Income & Equity Relationship

While net income generally remained within a relatively stable range throughout the period, shareholder equity consistently increased until May 2023. The subsequent decline in ROE, despite relatively stable net income, suggests that the growth in equity may be outpacing the growth in net income, or that equity is being reduced at a faster rate than net income declines. The most significant ROE drop coincides with a substantial decrease in net income in the final two periods.

In summary, the ROE initially demonstrated strong growth, followed by a period of stabilization and then a significant decline with increasing volatility. The latter trend warrants further investigation to determine the underlying causes and potential implications for future performance.

The Return on Assets (ROA) exhibited a generally positive trajectory over the observed period, although with notable fluctuations. Initial values hovered around 8% in late 2020 and early 2021, before demonstrating substantial growth through the first half of 2021. Subsequently, the ROA experienced a period of stabilization and modest decline, followed by a recent downward trend.

Initial Growth Phase (Aug 31, 2020 – Aug 31, 2021)

From August 2020 to August 2021, the ROA increased from 8.09% to 16.04%. This represents a significant improvement in the company’s efficiency in utilizing its assets to generate profit. The most substantial increase occurred between February 2021 and August 2021, suggesting a particularly strong performance during that timeframe.

Stabilization and Moderate Decline (Nov 30, 2021 – Aug 31, 2022)

Following the peak in August 2021, the ROA experienced a period of stabilization, fluctuating between 15.45% and 16.04% for several quarters. A gradual decline then commenced, bringing the ROA down to 13.73% by August 2022. While still representing a healthy return, this indicates a lessening of asset utilization efficiency compared to the prior period.

Recent Downward Trend (Nov 30, 2022 – Aug 31, 2025)

From November 2022 onwards, a more pronounced downward trend in ROA is observed. The ratio decreased from 14.21% to 6.07% by February 2026. This decline appears to be accelerating in the most recent quarters, with the ROA falling from 11.93% in February 2025 to 6.07% in February 2026. This suggests increasing challenges in generating profits from the existing asset base.

Net Income and Total Assets Relationship

The ROA’s movements correlate with changes in both net income and total assets. While net income generally remained relatively stable, total assets consistently increased throughout most of the period. The recent decline in ROA is likely attributable to a combination of decreasing net income and continued growth in total assets, indicating that the company is generating less profit relative to its expanding asset base.

Overall, the ROA demonstrates a shift from strong growth and high performance to a period of decline. Further investigation into the factors driving the recent decrease in profitability relative to assets would be warranted.
