The analysis of the available financial data reveals several trends in the company's return metrics over the six-year period ending August 26, 2023.

Return on Assets (ROA)

The ROA demonstrates variability with both increases and decreases during the period examined. Starting at 14.31% in 2018, it rose significantly to 16.34% in 2019. However, the following year saw a notable decline to 12.01% in 2020. Subsequently, there was a recovery and steady improvement with ROA reaching 14.95% in 2021 and further increases to 15.91% in 2022. The most recent measurement in 2023 shows a slight decrease to 15.82%. Despite some fluctuations, the general trend indicates that the company has maintained an ROA within a relatively high range, suggesting consistent effectiveness in utilizing its assets to generate profit.

Financial Leverage

No data was reported for financial leverage across all periods, which limits the ability to assess the company’s use of debt or capital structure changes over time.

Return on Equity (ROE)

Similar to financial leverage, there is a complete absence of reported data for ROE. This creates a gap in the evaluation of overall shareholder return and the efficiency of equity financing.

Net Profit Margin
The net profit margin exhibited an upward trend from 2018 to 2022, increasing from 11.92% to 14.95%. This indicates improving profitability over the years. In 2023, a slight decline to 14.48% was observed, suggesting a marginal decrease in net profitability compared to the previous year, though it remained higher than the values recorded prior to 2021.
Asset Turnover
Asset turnover showed a stable level of 1.2 ratio in 2018 and 2019, indicating consistent efficiency in using assets to generate sales during this period. However, in 2020, there was a noticeable decline to 0.88, reflecting a reduction in asset utilization efficiency. Subsequently, there was a gradual recovery to 1.01 in 2021, 1.06 in 2022, and 1.09 in 2023, suggesting improving operational efficiency but not yet reaching the earlier peak levels of 2018 and 2019.
Financial Leverage
Financial leverage data is missing for all reported years, therefore no analysis regarding the use of debt or equity financing and its impact on the company’s capital structure can be provided.
Return on Equity (ROE)
The return on equity figures are not available for any of the periods, limiting the ability to assess how effectively the company has used shareholders' equity to generate profits over time.

The financial data presents several key ratios and margins that illustrate the company's operational efficiency, profitability, and financial health over a six-year period ending in 2023.

Tax Burden
The tax burden ratio exhibits a gradual decline from 0.82 in 2018 to a low of 0.78 in 2020, followed by a slight recovery stabilizing around 0.79 to 0.80 in the subsequent years up to 2023. This pattern indicates a modest improvement in the company's after-tax profitability efficiency in the earlier years, with stability maintained thereafter.
Interest Burden
The interest burden ratio shows a generally upward trend from 0.90 in 2018 to a peak of 0.94 in 2022, before slightly decreasing to 0.91 in 2023. This suggests a varying yet overall increased ability to cover interest expenses from operations, implying fluctuations in the company’s interest expense management or debt levels over time.
EBIT Margin
There is a consistent upward trend in EBIT margin from 16.19% in 2018 to a peak of 20.16% in both 2021 and 2022, with a minor decline to 19.97% in 2023. This indicates improving operational profitability, reflecting effective cost control and/or revenue growth contributing to a higher earnings margin before interest and taxes.
Asset Turnover
Asset turnover begins at 1.20 in 2018 and remains steady in 2019, followed by a significant decline to 0.88 in 2020. A recovery is noted thereafter, with progressive increases reaching 1.09 in 2023. This fluctuation reveals a temporary decrease in asset utilization efficiency, likely tied to asset base growth or operational changes, and subsequent improvement suggesting more effective use of assets to generate revenue.
Financial Leverage and Return on Equity (ROE)
Data for financial leverage and return on equity are missing, limiting analysis of the company’s capital structure and the overall profitability generated on shareholders’ equity.

Overall, the data indicate that the company has improved its operational profitability, as reflected in higher EBIT margins and stable tax burden rates. Despite some volatility in asset utilization, asset turnover shows recovery in recent years. Interest burden ratios suggest a manageable but varying cost of debt service. The absence of financial leverage and ROE data restricts a complete evaluation of financial risk and shareholder returns.

Net Profit Margin
The net profit margin demonstrates a generally positive trend over the examined period, rising from 11.92% in 2018 to a peak of 14.95% in 2022, followed by a slight decline to 14.48% in 2023. This indicates improved profitability efficiency with a stable margin above 13.5% after 2019, reflecting effective cost management or favorable pricing strategies in recent years.
Asset Turnover
The asset turnover ratio showed stability at 1.2 during 2018 and 2019 before experiencing a notable decrease to 0.88 in 2020. Subsequently, the ratio recovered gradually, reaching 1.09 by 2023. This pattern points to a temporary reduction in operational efficiency or asset utilization efficiency during 2020, potentially due to external factors, with a steady improvement through 2023.
Return on Assets (ROA)
Return on assets fluctuated in alignment with trends in profit margin and asset turnover, beginning at 14.31% in 2018 and increasing to 16.34% in 2019. A decline occurred in 2020 to 12.01%, followed by recovery to 15.82% in 2023. The ROA reflects the combined impact of changes in net profit margin and asset turnover, suggesting that despite pandemic-related challenges in 2020, the company's asset profitability has strengthened over the latter years.

Tax Burden
The Tax Burden ratio demonstrated a gradual decline from 0.82 in 2018 to 0.78 in 2020, before stabilizing around 0.79 to 0.80 in the subsequent years up to 2023. This indicates a slight decrease in the proportion of earnings lost to taxes initially, followed by relative consistency in recent years.
Interest Burden
The Interest Burden ratio displayed a generally upward trend from 0.90 in 2018 to a peak of 0.94 in 2022, with a slight decline to 0.91 in 2023. This suggests that the proportion of earnings retained after interest expenses increased modestly before a minor contraction in the most recent year.
EBIT Margin
The EBIT Margin showed steady improvement from 16.19% in 2018 to a peak of 20.16% in 2021 and 2022, with a marginal decrease to 19.97% in 2023. This reflects enhanced profitability from core operations over the period, reaching a plateau in the last two years.
Asset Turnover
Asset Turnover experienced a notable decline from a consistent 1.20 ratio in 2018 and 2019 to 0.88 in 2020. It then recovered steadily, reaching 1.09 by 2023. This pattern suggests a temporary reduction in asset utilization efficiency, followed by gradual improvement.
Return on Assets (ROA)
ROA followed a fluctuating trend, increasing from 14.31% in 2018 to 16.34% in 2019, then declining sharply to 12.01% in 2020. Subsequently, it regained momentum, rising to 15.91% in 2022 and stabilizing slightly lower at 15.82% in 2023. This corresponds with the movements observed in EBIT Margin and Asset Turnover, indicating operational and efficiency impacts on overall asset profitability.
