Return on Assets (ROA)

The ROA demonstrated notable fluctuations over the observed periods. Initially, starting at a low of 0.45%, it increased sharply to a peak of 11.02% by the third quarter of 2021, indicating improving efficiency in asset utilization. Subsequently, it declined somewhat, stabilizing around the 5% to 9% range through most of 2022 and 2023. An unusual dip occurred during early to mid-2024, reaching lows near 0.23%, before rebounding strongly toward the end of the timeframe, with ROA climbing consistently from 10.57% to 13.86% by the third quarter of 2025. This rebound suggests a recovery or operational improvement in asset use effectiveness.

Financial Leverage

Financial leverage exhibited a gradual declining trend over the entire period. Starting at 3.56 times in early 2021, leverage steadily decreased to around 2.72 times by the third quarter of 2025. This decline suggests a gradual reduction in reliance on debt financing or an increase in equity base relative to debt, indicating a potentially more conservative capital structure and lower financial risk as time progressed.

Return on Equity (ROE)

ROE showed strong volatility similar to ROA but with generally higher values, reflecting the impact of financial leverage on equity returns. From a low of 1.59% in early 2021, ROE surged to a peak of 34.44% by the third quarter of 2021, suggesting very strong profitability relative to shareholders' equity. Although ROE declined through 2022 to a range near 15% to 26%, it remained elevated compared to the start of 2021. A pronounced dip occurred in the first half of 2024, with ROE decreasing to below 1%, before a significant recovery that propelled ROE to a new high of 37.65% by the third quarter of 2025. This pattern indicates periods of both weakness and strength in shareholder returns, with recent gains reflecting improved profitability and possibly operational leverage effects.

Overall Insights

The financial data reveal a company experiencing cyclical performance trends, with key profitability ratios (ROA and ROE) capturing periods of both challenge and recovery. The steady decrease in financial leverage is noteworthy as it likely contributed to the volatility in ROE, moderating risk over time. The sharp recoveries in profitability toward the end of the timeline suggest strategic or market shifts resulting in enhanced financial performance. Continuous monitoring of these metrics would be prudent to assess sustainability of recent improvements.

The financial data presents key performance ratios over multiple quarterly periods, highlighting fluctuations and trends in profitability, asset utilization, and leverage.

Net Profit Margin

The net profit margin exhibited notable volatility throughout the observed quarters. Initially, it increased sharply from a low point of approximately 1.19% to a peak above 27% within the first year. Subsequently, margins declined, fluctuating between roughly 12% to 21% over the next few quarters. During a mid-period window, there was a significant drop with margins falling close to zero or just under 2%, indicating periods of diminished profitability. Toward the end of the series, the margin rebounded strongly reaching nearly 28%, signaling improved cost control or revenue generation efficiency.

Asset Turnover

Asset turnover ratios displayed a generally positive trend with slight fluctuations. Beginning near 0.37, there was a gradual climb to approximately 0.44 over the first two years. A moderate peak close to 0.52 was observed in the later periods, indicating improved efficiency in using assets to generate revenue. This upward trend suggests management's effectiveness in optimizing asset utilization despite minor dips.

Financial Leverage

Financial leverage decreased steadily from an initial ratio above 3.5 to a lower range around 2.7-3.2 over the time observed. This declining pattern implies a reduction in debt levels relative to equity, indicating a more conservative capital structure or efforts to deleverage. Minor variations within this band were evident, but no sharp increases suggest stable risk management policies.

Return on Equity (ROE)

Return on equity mirrored the trends in profit margin but with amplified variations due to leverage effects. ROE initially surged from under 2% to a high exceeding 34%, then experienced declines aligned with profit margin downturns. Notable troughs occurred along with mid-period dips in profitability, where ROE approached near-zero levels. The final quarters demonstrated a robust recovery with ROE climbing to nearly 38%, indicative of enhanced overall profitability, efficient asset use, and sustained leverage management.

Overall, the data reveals a cyclical performance pattern characterized by strong early gains in profitability and equity returns, a mid-cycle contraction period with weakened margins and returns, and a subsequent recovery phase. Asset turnover steadily improved, while financial leverage showed a deliberate reduction, suggesting prudence in financial risk management. The company's capacity to generate shareholder returns improved over time despite intermittent challenges.

The analysis of the quarterly financial ratios reveals distinct patterns and fluctuations over the observed periods.

Tax Burden

The tax burden ratio exhibits considerable variability, initially increasing from a low of 0.15 to around 0.79 by the end of 2021. The ratio remains relatively stable around the mid-0.7 to 0.8 range through 2023, followed by a notable dip in early 2024 to approximately 0.44. Subsequently, it gradually climbs back to elevated levels near 0.87 by mid-2025. This suggests fluctuating effective tax rates or tax-related impacts on net income during these quarters.

Interest Burden

Interest burden begins at 0.66 and generally trends upward to about 0.9 through 2021, indicating a moderate reduction in interest expenses relative to earnings before taxes. However, a sharp decline to as low as 0.16 occurs in late 2024, after which the ratio quickly recovers to levels near 0.9 by mid-2025. Such volatility may imply episodic changes in debt servicing costs or interest expense recognition.

EBIT Margin

The EBIT margin shows significant fluctuations, starting at 11.73% and peaking near 38.22% in late 2021, followed by a decline to below 21% during late 2022. It then stabilizes around 29-30% during 2023, but again dips markedly to lows around 4-7% in early to late 2024. A strong rebound occurs in 2025 with margins reaching above 38%, reflecting volatility in operating profitability possibly driven by changes in revenue, costs, or pricing strategies.

Asset Turnover

Asset turnover demonstrates a consistent gradual upward trend, improving from 0.37 in early 2021 to levels around 0.52 by late 2024 and mid-2025. This trend indicates a progressive enhancement in asset utilization efficiency to generate revenue over time.

Financial Leverage

Financial leverage ratios decline from a high of 3.56 in early 2021 to approximately 2.72 by late 2023, suggesting a reduction in reliance on debt or an increase in equity. Slight fluctuations occur thereafter, but overall leverage remains lower than the initial periods, signifying potential deleveraging or asset base growth strategies.

Return on Equity (ROE)

ROE exhibits wide variability, surging from 1.59% to a peak of 34.44% in late 2021 before falling to below 16% in late 2022. The ratio recovers to consistent mid-to-high 20% levels in 2023, plunges sharply to below 3% throughout much of 2024, and ultimately rebounds significantly to exceed 37% by late 2025. This demonstrates the company’s fluctuating profitability and effectiveness at generating returns on shareholders’ equity, likely influenced by operating performance, leverage, and tax impacts.

Overall, the data presents cycles of strong profitability and returns interspersed with periods of subdued performance, accompanied by improvements in asset efficiency and a trend toward lowered financial leverage. Significant fluctuations in tax and interest burdens correspond with variations in underlying earnings metrics, suggesting sensitivity to external factors or internal financial management decisions across the observed timeframe.

The financial performance indicators exhibit notable fluctuations over the observed periods, reflecting varying operational efficiency and profitability dynamics.

Net Profit Margin

The net profit margin showed a significant improvement early on, rising from a marginal 1.19% to a peak of approximately 27.21% within the first year. This elevated level slightly receded but remained relatively strong through subsequent quarters, stabilizing mostly between 15% and 22% for several periods. However, a sharp decline is apparent around the early part of 2024, where margins dropped sharply to below 4%, hitting as low as 0.45% before recovering again towards the end of the observed timeline, returning to a high of 28.41%. This pattern indicates episodic variability potentially linked to factors such as atypical expenses or revenue fluctuations.

Asset Turnover

The asset turnover ratio exhibited a gradual and steady increase over the review period, beginning at 0.37 and moving to slightly above 0.5 in some later quarters. This steady upward trend suggests enhanced efficiency in using assets to generate revenue over time, with minor volatility. The consistency beyond the initial years indicates stability in asset utilization practices.

Return on Assets (ROA)

Return on assets generally followed a similar pattern to net profit margin, with an initial sharp increase from below 1% to above 11%, peaking around the second year. After fluctuating, ROA maintained levels between approximately 5% and 9% for several quarters. A notable decline occurred in early 2024, where ROA fell below 2%, even reaching near zero or slightly negative values, before recovering strongly toward the end of the period and rising to nearly 14%. This tendency reflects variable profitability in relation to assets over time and aligns with observed net margin fluctuations.

Overall, the data indicates that while operational efficiency as measured by asset turnover has improved consistently, profitability metrics have experienced significant volatility. The periods of decline in profit margin and ROA, notably in early 2024, suggest potential challenges that impacted income generation more than asset utilization. Recovery towards the end of the timeline signals a possible return to higher profitability and improved asset returns.

Tax Burden

The tax burden ratio fluctuated considerably over the analyzed quarters. It started very low at 0.15, then jumped to values around 0.74 to 0.82 for several quarters. There was a notable dip to 0.44 in early 2024, followed by a recovery and an increasing trend towards 0.87 to 0.88 at the end of the period. This indicates variable effective tax rates impacting the net income over time.

Interest Burden

The interest burden ratio demonstrated general stability for the majority of the quarters, consistently staying around the 0.85 to 0.91 range, with brief drops observed in early to mid-2024. The sharp decline to 0.16 in September 2024 and subsequent partial recovery suggests temporary changes in interest expenses or changes in financial leverage during that period. The ratio stabilized again near 0.9 by the end of the dataset.

EBIT Margin (%)

The EBIT margin showed significant volatility. It peaked at 38.22% in the third quarter of 2021, followed by a decline through late 2023 and early 2024, reaching single-digit margins as low as 4.16% in the third quarter of 2024. Subsequently, the margin recovered sharply to above 27% by early 2025, reaching back near the previous peaks by the last quarter. This pattern indicates periods of both strong profitability and relative contraction in earnings before interest and taxes.

Asset Turnover

The asset turnover ratio displayed a gradual upward trend with minor fluctuations. Starting around 0.37, it improved steadily to peak around 0.52 in mid-2024 and remained near this higher level slightly declining towards 0.49 by the third quarter of 2025. This suggests an improving efficiency in generating revenue from assets over the period.

Return on Assets (ROA) (%)

The ROA exhibited considerable variation, with values ranging from a low of 0.23% in the third quarter of 2024 to a high of 13.86% in the third quarter of 2025. There was a noticeable decline in early 2024, aligning with lower EBIT margins and interest burden fluctuations, followed by a strong recovery towards the end of the period. Overall, the trend suggests a cyclical pattern with phases of suppressed profitability and subsequent strong asset returns.

Summary

The financial ratios reveal a dynamic performance pattern characterized by fluctuating profitability and tax effects, combined with steady improvements in asset utilization. Periods of profitability contraction are evident around early to mid-2024, likely driven by changes in operational earnings and interest expenses. However, the latter part of the timeline shows signs of recovery and stronger returns on assets, indicating effective management of operational efficiency and financial costs moving forward.

Tax Burden

The tax burden ratio exhibits significant fluctuations across the observed periods. Initially, there is a marked increase from a low of 0.15 to values hovering around 0.7 to 0.8 between mid-2021 and early 2024. A notable dip occurs in early 2024, reducing to approximately 0.44, followed by a gradual recovery towards higher levels near 0.87 to 0.82 in the last quarters. These variations suggest variable tax impacts on earnings across quarters, with occasional reductions in effective tax rates improving net profitability temporarily.

Interest Burden

The interest burden ratio generally remains within the range of 0.8 to 0.9 throughout most of the periods, indicating stable interest expenses relative to earnings before interest and taxes. However, there are intermittent declines, particularly in early to mid-2024 where the ratio drops sharply as low as 0.16, and in late 2024 where it recovers gradually. This volatility points to fluctuating interest expenses or earnings volatility influencing operational efficiency before tax effects.

EBIT Margin

The EBIT margin reveals notable quarter-to-quarter fluctuations. Early observations show a steep rise from around 11.7% to a peak near 38.2%, indicating periods of improving operational profitability. Following this, a decline is evident through 2022 and into early 2024, touching lows around 4.16% to 7.58%. From late 2024 onward, the margin rebounds strongly, reaching again around 38.2% by late 2025. This pattern suggests cycles of operational efficiency and possibly varying revenue or cost dynamics affecting earnings before interest and taxes.

Net Profit Margin

The net profit margin aligns in pattern with EBIT margin but shows more pronounced volatility. Initial quarters reflect low margin levels near 1.19%, escalating substantially to over 27% in late 2021, which points to a significant improvement in bottom-line profitability. Thereafter, a decline occurs during 2022 extending into early 2024, with margins dropping as low as 0.45%. Subsequently, there is a recovery phase toward margins exceeding 28% by the end of the period. This variation emphasizes the impact of the combined effects of interest, tax burdens, and operational margins on net profitability.

Overall Analysis

The financial ratios demonstrate cyclical behavior with phases of strong profitability alternating with periods of contraction. Operational margin fluctuations are closely mirrored by net profit margin changes, underscored by varying tax and interest burdens. These patterns may indicate sensitivity to external market conditions, internal cost management, or capital structure adjustments over time. The recovery of margins toward the later periods suggests effective management of expenses and tax efficiency, resulting in enhanced profitability by the end of the observed timeline.
