The financial performance over the analyzed periods exhibits notable trends in profitability and leverage ratios.

Return on Assets (ROA)
The ROA shows a declining trend from 1.53% in 2020 to 1.23% in 2022, indicating diminishing efficiency in asset utilization during this period. However, a significant improvement is observed starting in 2023, with ROA increasing to 4.00% and further to 5.45% in 2024, reflecting enhanced asset management and profitability.
Financial Leverage
The financial leverage ratio remained relatively stable between 2020 and 2022, fluctuating slightly around the 3.0 mark. Subsequently, an upward movement occurs, reaching 3.21 in 2023 and 3.37 in 2024. This increase suggests a moderate rise in the use of debt financing or other liabilities relative to equity.
Return on Equity (ROE)
ROE mirrors the initial decline seen in ROA, decreasing from 4.69% in 2020 to 3.72% in 2022. The ratio then experiences a marked escalation to 12.85% in 2023 and 18.37% in 2024, signaling substantial growth in shareholder returns and improved profitability. The rise is proportionally greater than the increase in financial leverage, implying efficiency gains beyond just leverage effects.

In summary, the company demonstrated weakening profitability up to 2022, followed by a strong recovery in 2023 and 2024. The moderate increase in financial leverage during the latter years accompanied significant improvements in both ROA and ROE, indicating enhanced operational performance and effective capital structure management.

Net Profit Margin
The net profit margin shows a declining trend from 4.48% in 2020 to 3.25% in 2022, suggesting a reduction in profitability relative to revenue during this period. However, a significant improvement is observed in 2023 and 2024, with the margin increasing substantially to 10.59% and 13.93% respectively, indicating enhanced operational efficiency or cost management in the later years.
Asset Turnover
The asset turnover ratio demonstrates relative stability over the five-year period. Beginning at 0.34 in 2020, it increases to 0.39 in 2021, then slightly dips to 0.38 in 2022 and 2023, before returning to 0.39 in 2024. This consistency suggests that the company maintained steady effectiveness in utilizing its assets to generate revenue.
Financial Leverage
The financial leverage ratio remains close to 3 throughout the period but shows a gradual increase from 3.06 in 2020 to 3.37 in 2024. This indicates a cautious but progressive use of debt relative to equity, potentially to finance growth or operations, with slightly higher financial risk evident towards the end of the timeframe.
Return on Equity (ROE)
ROE trends align with changes observed in net profit margin, starting at 4.69% in 2020 and declining to 3.72% in 2022, reflecting reduced profitability. A marked rebound occurs in 2023 and 2024, as ROE rises sharply to 12.85% and 18.37%, respectively, signifying improved overall profitability and effective use of equity capital in the later years. The increase in financial leverage likely contributes to this pronounced gain in ROE.

The analysis of the financial ratios over the five-year period reveals distinct trends in profitability, asset utilization, and overall efficiency.

Net Profit Margin
The net profit margin shows a fluctuating but ultimately upward trajectory. Starting at 4.48% in 2020, it declined to 3.25% by the end of 2022 before experiencing a significant increase to 10.59% in 2023 and further rising to 13.93% in 2024. This indicates improving profitability and cost management in the most recent years, suggesting enhanced operational efficiency or higher revenue relative to expenses.
Asset Turnover
The asset turnover ratio remains relatively stable throughout the period, with minor variations between 0.34 and 0.39. This consistency suggests that the company maintained steady efficiency in using its assets to generate sales volume without significant growth or decline in asset productivity.
Return on Assets (ROA)
The ROA displays a modest decline from 1.53% in 2020 to 1.23% in 2022, mirroring the net profit margin trend in the early years. However, a marked improvement occurs from 2023 onward, with ROA rising sharply to 4.00% and then to 5.45% in 2024. This pattern reflects improved overall asset profitability, likely driven by the increase in net profit margins while maintaining stable asset turnover.

In summary, the data indicates that while asset utilization has been relatively consistent, the company has substantially improved its profitability and return on assets in the latter years of the period. The significant rise in net profit margin and ROA suggests enhanced operational performance and better capital efficiency.

The analysis of the annual financial data reveals several notable trends over the five-year period examined.

Tax Burden
The tax burden ratio exhibits some fluctuation, with an initial increase from 0.80 in 2020 to 0.90 in 2021, followed by a decline to 0.82 in 2022. Subsequently, it decreases further to 0.76 in 2023 and slightly rises to 0.77 in 2024. Overall, the recent years show a lower tax burden compared to the early period.
Interest Burden
This ratio decreases from 0.59 in 2020 to a low of 0.48 in 2022, indicating an improvement in managing interest expenses or debt servicing costs during these years. However, in 2023 and 2024, there is a notable increase to 0.77 and 0.81, respectively, which may signal rising interest expenses or changes in leverage.
EBIT Margin
The EBIT margin shows a declining trend from 9.58% in 2020 to 8.18% in 2022, suggesting pressure on operational profitability during this time. This trend reverses dramatically in 2023 with a sharp increase to 18.25%, continuing upward to 22.26% in 2024, reflecting significantly improved operating efficiency or revenue growth relative to operating expenses.
Asset Turnover
Asset turnover remains relatively stable throughout the period, fluctuating narrowly between 0.34 and 0.39. This stability indicates consistent efficiency in utilizing assets to generate sales.
Return on Assets (ROA)
ROA diminishes slightly from 1.53% in 2020 to 1.23% in 2022, parallel to the trends in EBIT margin and interest burden, implying reduced profitability relative to asset base. However, it rebounds substantially from 2023 onward, reaching 4.00% and 5.45% in 2023 and 2024 respectively, which aligns with the improvement in EBIT margin and suggests enhanced overall company profitability supported by better operational performance and asset use.

In summary, the data indicates a period of operational and financial challenge in the early years, followed by marked improvement in profitability and efficiency metrics from 2023 onwards. Increasing EBIT margin and ROA in recent years suggests successful strategic or market developments that favorably impacted earnings and asset returns. Meanwhile, rising interest burden in later years may warrant further examination for potential impacts on financial risk.

The analysis of the financial ratios over the five-year period reveals several significant trends that reflect the company's operational efficiency and profitability dynamics.

Tax Burden
The tax burden ratio has shown moderate fluctuations, starting at 0.80 in 2020 and peaking at 0.90 in 2021 before declining to 0.76 in 2023. It slightly increased to 0.77 in 2024. This pattern indicates some variability in effective tax rates, with a general downward trend after 2021, suggesting improved tax efficiency or changes in tax regulations impacting net income.
Interest Burden
The interest burden ratio exhibited a declining trend from 0.59 in 2020 to a low of 0.48 in 2022, followed by a sharp increase to 0.77 in 2023 and further to 0.81 in 2024. This reversal suggests that the company's interest expenses relative to EBIT were initially decreasing, improving operating income available to cover interest, but subsequently increased significantly, implying higher interest expenses or reduced EBIT in later years.
EBIT Margin
The EBIT margin showed a consistent decline from 9.58% in 2020 to 8.18% in 2022, indicating margin compression during this period. However, there was a marked improvement starting in 2023, with EBIT margin rising drastically to 18.25% and further to 22.26% in 2024. This reflects substantial enhancements in operating profitability, possibly driven by cost control, revenue growth, or operational efficiencies.
Net Profit Margin
The net profit margin mirrors the trend in EBIT margin but with even more pronounced improvements. The margin fell from 4.48% in 2020 to 3.25% in 2022, indicating weakening profitability at the net income level. From 2023 onwards, there was a strong recovery with net profit margin increasing to 10.59% and further to 13.93% in 2024. This suggests that factors beyond operating performance, such as tax management and interest burden changes, substantially contributed to enhancing net profitability.

Overall, the data indicates that while the company experienced margin pressures in the early years, it successfully reversed these trends from 2023 onwards, achieving significant gains in both operating and net profitability. The contrasting movements in interest burden suggest changing financial cost structures impacting earnings, whereas the relatively stable tax burden in the latter years supports the improved net margins. These patterns point to improved operational performance combined with financial management strategies that enhanced profitability in the most recent periods.
