Profitability metrics exhibit a distinct cyclical trajectory characterized by an initial period of expansion, a mid-term contraction, and a subsequent strong recovery phase extending through the final periods of the analysis.

Margin Performance

Gross profit margin remained relatively stable between 44% and 47% for the first several years, reaching a trough of 44.62% in June 2023. Following this period, a consistent upward trend is observed, with margins expanding to a peak of 49.98% by March 2026. Operating and net profit margins followed a similar U-shaped pattern; both ratios peaked between late 2021 and early 2022, experienced a decline that bottomed out in December 2023, and then grew steadily to reach their highest recorded levels by the end of the period, with the operating margin ending at 34.26% and the net margin at 30.94%.

Returns on Investment

Return on Equity (ROE) and Return on Assets (ROA) demonstrated significantly higher volatility than the profit margins. ROE increased sharply from 48.15% in September 2020 to a peak of 75.35% in March 2022, before retreating to a low of 42.06% in December 2023. A recovery phase began in 2024, bringing ROE back to 63.38% by March 2026. ROA mirrored this movement, rising from 17.33% to a peak of 27.51% in December 2021, dropping to 18.41% in December 2023, and eventually accelerating to a period-high of 32.26% by March 2026.

Correlation and Efficiency

A strong positive correlation is evident between the margin expansions and the returns on assets and equity. The synchronized recovery observed from 2024 onward suggests a comprehensive improvement in operational efficiency and asset utilization. The fact that ROA and ROE ended at levels higher than or comparable to their previous peaks, while gross margins reached new highs, indicates an enhanced ability to convert revenue into net income and generate value from the company's resource base.

The gross profit margin exhibits three distinct phases over the analyzed period: an initial stage of stability, a period of moderate contraction, and a subsequent phase of sustained expansion.

Margin Stability and Initial Decline

Between September 2020 and December 2021, the gross profit margin remained remarkably consistent, fluctuating within a narrow range between 46.19% and 46.59%. Starting in March 2022, a downward trend emerged, characterized by a gradual compression of margins that reached a cyclical trough of 44.62% in June 2023.

Recovery and Margin Expansion

A reversal of the declining trend began in the second half of 2023. From September 2023 through March 2026, the gross profit margin demonstrated consistent sequential growth. This expansion became more pronounced starting in March 2024, where the margin rose from 46.84% to conclude at a period high of 49.98% by March 2026.

Correlation Between Revenue and Profitability

Absolute gross margin and revenue followed a synchronized cyclical pattern. Revenue peaked in December 2022 at approximately $5.28 billion before experiencing a significant contraction that bottomed in June 2023 at $3.21 billion. The subsequent recovery in revenue, which reached $5.84 billion by March 2026, coincided with the expansion of the gross profit margin percentage. This suggests that the increase in absolute profitability was driven not only by higher sales volumes but also by improved operational efficiency or a more favorable product mix.

The operating profit margin exhibits a cyclical trajectory over the analyzed period, characterized by an initial growth phase, a period of margin compression, and a subsequent robust recovery that surpasses previous peak levels.

Initial Expansion Phase (September 2020 – December 2022)

A consistent upward trend in profitability is observed during this period. The operating profit margin grew from 28.02% in September 2020 to a peak of 31.76% by December 2022. This growth was supported by a steady increase in revenue, which rose from approximately 3.18 billion to 5.28 billion US dollars, indicating an improvement in operational efficiency as the scale of operations expanded.

Period of Margin Compression (March 2023 – December 2023)

A significant downturn occurred throughout 2023, with the operating profit margin declining from 30.76% in March 2023 to a period low of 27.08% in December 2023. This contraction coincided with a sharp decrease in revenue, which bottomed out at approximately 3.21 billion US dollars in June 2023. The simultaneous drop in both revenue and margin suggests that fixed costs exerted greater pressure on profitability during this period of lower demand.

Recovery and Peak Performance (March 2024 – March 2026)

Starting in March 2024, a sustained recovery is evident. The operating profit margin began a steady climb from 28.03%, accelerating through 2025 and 2026 to reach a high of 34.26% by March 2026. This recovery was driven by a strong rebound in revenue, which reached 5.84 billion US dollars in the final quarter. The fact that margins exceeded the 2022 peaks indicates a significant enhancement in cost management and operational leverage during the most recent growth phase.

Overall, the correlation between revenue fluctuations and operating margins is strong, though the final phase demonstrates a higher capacity for profitability per dollar of revenue than in previous cycles.

The net profit margin exhibits a long-term growth trajectory, characterized by an initial expansion phase, a period of volatility and contraction, and a final phase of significant margin optimization.

Initial Growth Phase (September 2020 – December 2021)

A consistent upward trend is observed, with the net profit margin rising from 23.60% to 27.78%. This period is marked by simultaneous increases in both revenue and net income, indicating strong operational efficiency during the scaling process.

Stability and Subsequent Contraction (March 2022 – December 2023)

Following a period of relative stability where margins hovered around 27% through late 2022, a downward trend emerged starting in early 2023. The net profit margin declined from 26.08% in March 2023 to a trough of 24.15% by December 2023, coinciding with a significant contraction in quarterly revenue.

Recovery and Margin Expansion (March 2024 – March 2026)

A robust recovery is evident beginning in early 2024, with margins steadily climbing from 25.35% to a peak of 30.94% by March 2026. The acceleration in profitability is particularly pronounced from June 2025 onwards, as the margin surpassed 29%. This expansion occurs alongside a recovery in revenue, which reached its highest point of 5,841,488 thousand dollars in the final quarter, suggesting enhanced cost management and improved operating leverage.

The analysis of profitability metrics reveals a cyclical trend in the return on equity (ROE), characterized by an initial surge, a prolonged contraction, and a subsequent recovery phase spanning from September 2020 to March 2026.

Return on Equity Trends

ROE exhibited a significant upward trajectory in the early period, rising from 48.15% in September 2020 to a peak of 75.35% in March 2022. Following this peak, a consistent downward trend was observed, with the ratio declining to a low of 42.06% by December 2023. Starting in March 2024, the metric entered a recovery phase, steadily climbing to reach 63.38% by March 2026.

Net Income Volatility

Net income demonstrated substantial fluctuations that directly influenced ROE. Earnings grew steadily from 823.45 million USD in September 2020 to a high of 1.468 billion USD in December 2022. A sharp contraction occurred in early 2023, with net income falling to 814.01 million USD in March 2023. However, a robust recovery followed, with earnings accelerating to a period high of 1.825 billion USD by March 2026.

Equity Base Expansion

Stockholders' equity showed a consistent long-term increase, growing from 5.42 billion USD in September 2020 to 10.58 billion USD in March 2026. The nearly twofold increase in the equity base created a higher threshold for maintaining high ROE levels, as the denominator in the profitability calculation expanded continuously.

Interdependency Analysis

The decline in ROE between March 2022 and December 2023 was driven by a dual pressure: the contraction of net income combined with the continued growth of stockholders' equity. Conversely, the rebound in ROE observed from 2024 through 2026 was propelled by net income growth that outpaced the expansion of the equity base, signaling an increase in the efficiency of capital utilization during the latter part of the period.

The Return on Assets (ROA) exhibits a cyclical pattern characterized by an initial period of rapid growth, a subsequent contraction, and a final phase of significant acceleration. Over the analyzed period, ROA fluctuated from a low of 17.33% in September 2020 to a peak of 32.26% by March 2026, reflecting varying levels of efficiency in utilizing the asset base to generate net income.

Initial Growth Phase (September 2020 – December 2021)

A consistent upward trend in ROA is observed, rising from 17.33% to a peak of 27.51%. This expansion was driven by a steady increase in net income, which grew from 823,451 thousand to 1,194,830 thousand, while total assets remained relatively stable, increasing only marginally from 15,057,008 thousand to 16,685,428 thousand.

Correction and Decline Phase (March 2022 – December 2023)

A gradual decline in ROA is evident, starting from 27.37% in March 2022 and reaching a trough of 18.41% in December 2023. During this period, total assets expanded significantly, peaking at 19,243,361 thousand in March 2023. The decline in ROA was exacerbated by a sharp reduction in net income in early 2023, where figures dropped to approximately 814,008 thousand, indicating a period of decreased asset productivity.

Recovery and Acceleration Phase (March 2024 – March 2026)

A strong recovery trend emerged beginning in March 2024, with ROA climbing steadily from 19.75% to 32.26%. This phase is marked by a substantial increase in net income, which reached 1,825,460 thousand by March 2026. While total assets continued to grow, peaking at 21,900,211 thousand in June 2025, the rate of income growth outpaced asset expansion, resulting in the highest recorded levels of operational efficiency.

Asset Utilization and Profitability Correlation

The relationship between total assets and net income demonstrates that profitability gains were not solely dependent on asset growth. The peak ROA of 32.26% was achieved despite the total asset base being approximately 38% larger than it was during the initial 2020 period, suggesting a significant improvement in the company's ability to extract value from its investments.
