An analysis of net income trends between 2021 and 2026 reveals a trajectory of initial growth, a mid-period contraction, and a subsequent strong recovery. Both reported and adjusted net income followed a similar directional pattern, peaking in 2023 before experiencing a decline in 2024 and 2025, followed by a significant increase in 2026.

Impact of Mark-to-Market Adjustments

The variance between reported and adjusted net income indicates the volatility of mark-to-market adjustments for available-for-sale securities. Between 2021 and 2023, these adjustments exerted a positive influence on reported earnings. This trend peaked in 2022, where reported net income exceeded adjusted net income by 561 million US$, suggesting substantial unrealized gains in the securities portfolio during that period.

Transition to Negative Valuation Adjustments

A shift in the valuation trend occurred in 2024, where mark-to-market adjustments began to act as a detractor from reported net income. In 2024 and 2025, reported net income was lower than adjusted net income by 199 million US$ and 184 million US$, respectively. This indicates a period of unrealized losses or downward valuation adjustments in the available-for-sale securities.

Convergence and Profitability Peak

By 2026, the gap between reported and adjusted net income narrowed significantly to 26 million US$, indicating a stabilization of the investment portfolio's market value. The final year of the period shows the highest overall profitability, with reported net income rising to 13,267 million US$, demonstrating that the growth was driven primarily by core operational results rather than investment gains.

An analysis of profitability ratios between July 2021 and July 2026 reveals a cyclical trend characterized by a peak in 2022, a subsequent contraction reaching a trough in 2025, and a recovery phase in 2026. The marginal differences between reported and adjusted figures indicate that mark-to-market adjustments for available-for-sale securities have a limited but consistent impact on the overall profitability profile.

Net Profit Margin

Reported net profit margins exhibited an upward trajectory from 21.26% in 2021 to a peak of 22.91% in 2022. A downward trend followed, with margins declining to 19.18% in 2024 and reaching a low of 17.97% in 2025, before recovering to 20.95% in 2026. Notably, the relationship between reported and adjusted margins shifted over time; while reported margins were higher than adjusted margins from 2021 to 2023, adjusted margins became the higher metric from 2024 through 2026, suggesting that unrealized losses on securities began to weigh down reported earnings in the later period.

Return on Equity (ROE)

ROE patterns closely mirror those of the net profit margin, peaking at a reported 29.70% in 2022. Efficiency in equity utilization declined over the following three years, falling to 21.73% by July 2025. The recovery in 2026 brought the reported ROE back to 26.38%. Adjusted ROE remained relatively stable compared to reported figures, though it consistently exceeded reported ROE starting in 2024, reaching 26.44% in 2026.

Return on Assets (ROA)

Asset profitability showed significant volatility, rising from 10.86% in 2021 to a high of 12.57% in 2022. A sharp contraction occurred in 2024, where reported ROA dropped to 8.29%, remaining nearly flat at 8.32% in 2025. A rebound is observed in 2026, with the ratio returning to 10.23%. As with other metrics, the adjusted ROA became marginally higher than the reported ROA from 2024 onwards, indicating that the adjustment for available-for-sale securities provided a slight lift to the underlying operational profitability during the period of decline.

The convergence of reported and adjusted ratios in 2026 across all three metrics suggests a stabilization of the impact of available-for-sale securities on the company's financial statements. The overall trend indicates a period of margin compression and reduced asset/equity efficiency between 2023 and 2025, followed by a return toward historical norms in 2026.

The financial performance over the analyzed period exhibits a cyclical trend characterized by initial expansion, a mid-term contraction, and a subsequent recovery in profitability margins.

Adjusted Net Profit Margin Trends

The adjusted net profit margin shows a steady upward trajectory from 20.99% in July 2021, reaching a peak of 22.02% in July 2023. This growth is followed by a two-year decline, with the margin compressing to 19.55% in 2024 and hitting a period low of 18.29% in 2025. A strong recovery is observed in July 2026, as the margin returns to 20.99%.

Net Income Correlation

Adjusted net income movements closely mirror the profit margin fluctuations. Earnings grew from US$ 10,458 million in 2021 to a peak of US$ 12,552 million in 2023. A subsequent contraction occurred through 2025, where adjusted net income fell to US$ 10,364 million, before surging to a period high of US$ 13,293 million in 2026.

Comparative Analysis of Reported and Adjusted Margins

A consistent narrow variance is observed between reported and adjusted net profit margins. The adjusted margins typically remain slightly higher than the reported figures, particularly during the downturn in 2024 and 2025. This indicates that non-recurring items or specific accounting adjustments exerted a modest negative impact on reported profitability, while the core adjusted operational efficiency remained slightly more resilient.

The financial performance from July 2021 through July 2026 is characterized by a period of growth peaking in 2023, a subsequent contraction between 2024 and 2025, and a strong recovery in the final year of the period.

Net Income Performance

Adjusted net income exhibited a steady increase from 10,458 million US$ in 2021 to a peak of 12,552 million US$ in 2023. This growth was followed by a two-year decline, reaching a period low of 10,364 million US$ in 2025. However, a significant rebound occurred in 2026, with adjusted net income rising to 13,293 million US$, the highest level within the observed timeframe.

Adjusted Return on Equity (ROE) Trends

The adjusted ROE followed a trajectory closely aligned with net income. The ratio rose from 25.34% in 2021 to peak at 28.30% in 2023. A downward trend was observed over the next two years, with the ratio contracting to 22.12% by July 2025. This decline was reversed in 2026, as the adjusted ROE ascended to 26.44%, signaling a restoration of capital efficiency.

Comparative Analysis of Reported and Adjusted Metrics

There is a high degree of correlation between reported and adjusted figures throughout the period. The variance between reported ROE and adjusted ROE remains minimal, typically staying within a range of approximately 0.1% to 1.4%. This suggests that one-time items or non-operating adjustments have had a limited impact on the overall measurement of equity returns.

Profitability and Equity Efficiency Correlation

The synchronization between the fluctuations in adjusted net income and adjusted ROE indicates that the changes in equity returns were primarily driven by earnings volatility rather than significant shifts in the equity base. The recovery in 2026 is particularly notable, as both net income and ROE reached new heights, suggesting improved operational leverage or effective cost management.

An analysis of the financial performance from 2021 to 2026 reveals a cyclical pattern in both profitability and asset efficiency. Adjusted net income and Adjusted Return on Assets (ROA) experienced a period of growth through 2023, followed by a contraction in 2024 and 2025, before rebounding strongly in 2026.

Adjusted Net Income Trends

Adjusted net income increased from US$ 10,458 million in 2021 to a peak of US$ 12,552 million in 2023. A subsequent decline was observed over the following two fiscal years, with values dipping to US$ 10,519 million in 2024 and US$ 10,364 million in 2025. This downward trend reversed sharply in 2026, with adjusted net income reaching its highest point in the analyzed period at US$ 13,293 million.

Adjusted Return on Assets (ROA) Analysis

The Adjusted ROA followed a trajectory closely aligned with net income, rising from 10.73% in 2021 to 12.32% in 2023. A significant contraction occurred in 2024, where the ratio dropped to 8.45%, remaining nearly flat at 8.47% in 2025. By 2026, the Adjusted ROA recovered to 10.25%, indicating an improvement in the efficiency of asset utilization.

Comparative Variance and Asset Efficiency

A consistent and narrow gap is maintained between reported and adjusted ROA figures across all periods, suggesting that non-recurring items have had a negligible impact on the overall assessment of asset productivity. The observed decline in ROA during 2024 and 2025, occurring while adjusted net income remained relatively stable compared to 2021 levels, suggests a likely increase in the total asset base during those years, which temporarily diluted the return on investment.
