The analysis of the financial performance from 2021 to 2026 reveals a cyclical trajectory in capital efficiency, characterized by an initial period of rapid optimization followed by a significant dilution of returns due to an expansive increase in the capital base.

Net Operating Profit After Taxes (NOPAT)

A strong upward trend is observed between 2021 and 2023, with NOPAT increasing from 845 million to a peak of 2,610 million. Following this peak, a period of volatility ensues; profits decline to 1,791 million by 2025 before showing a modest recovery to 1,992 million in 2026. This suggests a phase of high growth followed by a period of operational contraction or margin pressure.

Invested Capital Growth

Invested capital shows a steady and incremental increase from 7,361 million in 2021 to 12,434 million in 2025. However, a disproportionate surge occurs in 2026, where invested capital rises sharply to 37,471 million. This substantial increase indicates a major capital allocation event, such as a large-scale acquisition or significant infrastructure investment, which dramatically alters the company's asset base.

Return on Invested Capital (ROIC) Dynamics

ROIC exhibits a sharp ascent in the early period, peaking at 28.59% in 2023, which coincides with NOPAT growth outpacing the growth of invested capital. After 2023, a consistent downward trend emerges. The ROIC declines to 14.40% in 2025 and reaches a low of 5.32% in 2026. The precipitous drop in the final year is primarily driven by the massive expansion of the invested capital base, which has not yet been matched by a proportional increase in operating profits.

In summary, the efficiency of capital utilization peaked in 2023. The subsequent decline in ROIC reflects a transition from an organic growth phase to a capital-intensive phase, where the expanded investment base has yet to yield commensurate operating returns.

The Return on Invested Capital (ROIC) exhibited a bell-shaped trajectory over the analyzed period, peaking in 2023 before entering a significant decline. After an initial growth phase where ROIC rose from 11.48% in 2021 to a high of 28.59% in 2023, a consistent downward trend occurred, culminating in a low of 5.32% by 2026.

Operating Profit Margin (OPM)

Profitability margins showed strong expansion in the early years, rising from 16.95% in 2021 to a peak of 29.22% in 2023. This period of expansion was followed by a gradual erosion of margins, which declined to 24.12% in 2025 and dropped sharply to 16.34% in 2026, effectively returning to 2021 levels.

Turnover of Capital (TO)

Capital efficiency improved steadily between 2021 and 2023, reaching a peak ratio of 1.01. However, a subsequent decline in asset productivity is evident, with the ratio falling to 0.94 in 2024 and 0.84 in 2025. A severe contraction occurred in 2026, where the turnover ratio fell to 0.36, indicating a substantial decrease in the ability to generate revenue from the invested capital base.

Effective Cash Tax Rate Impact (1 – CTR)

The tax retention component remained relatively high and stable through 2023, peaking at 97.17%. A noticeable dip in tax efficiency occurred between 2024 and 2025, with the retention rate falling to 70.75%, suggesting a higher effective cash tax burden during this window. The rate recovered to 90.45% in 2026.

ROIC Decomposition Synthesis

The peak in ROIC during 2023 was the result of a synchronized optimization of both operating margins and capital turnover, combined with a minimal tax burden. The subsequent collapse in ROIC was primarily driven by the precipitous drop in capital turnover and the simultaneous compression of operating profit margins, which together outweighed the recovery in the tax retention rate seen in 2026.

The financial trajectory between July 31, 2021, and July 31, 2026, is characterized by an initial period of aggressive efficiency gains followed by a significant contraction in operating profitability despite continued top-line growth.

Revenue and Operating Profit Correlation

Adjusted revenue exhibited consistent growth over the six-year period, increasing from 5,470 million US$ in 2021 to 13,484 million US$ in 2026. Net operating profit before taxes (NOPBT) mirrored this growth through 2024, peaking at 2,886 million US$. However, a divergence occurred starting in 2025; while revenue continued to rise, NOPBT began a downward trend, falling to 2,203 million US$ by 2026.

Operating Profit Margin (OPM) Dynamics

The operating profit margin followed a bell-shaped trajectory. An expansion phase occurred from 2021 to 2023, where OPM rose from 16.95% to a peak of 29.22%. This indicates a period of high operational leverage and improving cost efficiency. Following this peak, a sustained contraction is observed, with the margin declining to 28.26% in 2024, 24.12% in 2025, and finally reaching 16.34% in 2026.

Profitability Erosion and Scale

By July 31, 2026, the operating profit margin effectively reverted to 2021 levels (16.34% compared to 16.95%), despite the company achieving more than double its 2021 revenue. The decline in NOPBT during the final two years of the period suggests that the costs associated with generating incremental revenue have increased substantially, leading to significant margin compression.

The financial trajectory from 2021 to 2026 reflects a period of aggressive expansion characterized by consistent revenue growth and a substantial increase in invested capital, which significantly impacted asset efficiency in the latter stages of the period.

Adjusted Revenue Growth

Revenue demonstrated a consistent upward trend, increasing from US$ 5,470 million in 2021 to US$ 13,484 million by 2026. While the growth was robust between 2021 and 2023, a period of relative stabilization occurred between 2024 and 2025 before a significant acceleration in the final year.

Invested Capital Dynamics

Invested capital increased moderately from 2021 through 2025, growing from US$ 7,361 million to US$ 12,434 million. However, a sharp escalation is observed in 2026, where invested capital surged to US$ 37,471 million, representing a nearly threefold increase over the preceding year.

Turnover of Capital Analysis

The turnover ratio exhibited an initial improvement, rising from 0.74 in 2021 to a peak of 1.01 in 2023, indicating an increase in the efficiency of capital utilization. This trend reversed after 2023, with a gradual decline to 0.84 by 2025. A severe contraction occurred in 2026, with the ratio falling to 0.36, a direct consequence of the massive surge in invested capital outpacing the growth in adjusted revenue.

The effective cash tax rate (CTR) exhibits substantial volatility between 2021 and 2026, characterized by an initial period of tax compression, a sharp surge to a peak, and a subsequent correction. This volatility appears decoupled from the trajectory of Net Operating Profit Before Taxes (NOPBT), which grew consistently from 2021 through 2024 before entering a moderate decline.

Initial Tax Compression (2021-2023)

A downward trend in the CTR is observed during this interval, falling from 8.83% in 2021 to a minimum of 2.83% in 2023. This decline occurred despite a significant expansion in NOPBT, which increased from 927 million to 2,686 million. Cash operating taxes remained relatively flat, ranging between 68 million and 82 million, suggesting that operating profitability grew at a much faster rate than the actual cash tax outflows.

Tax Acceleration and Peak (2024-2025)

A sharp reversal in the tax trend began in 2024, with the CTR climbing to 13.32% and reaching a peak of 29.25% in 2025. This spike was driven by a dramatic escalation in cash operating taxes, which rose from 76 million in 2023 to 741 million in 2025. The peak CTR in 2025 occurred during a period where NOPBT had already begun to decline from its 2024 high of 2,886 million, resulting in a significantly higher tax burden relative to earnings.

Recent Normalization (2026)

The CTR underwent a significant reduction in 2026, falling to 9.55%. This movement is primarily attributed to a decrease in cash operating taxes, which dropped to 210 million. While NOPBT continued to trend downward to 2,203 million, the decrease in cash tax payments was more pronounced, returning the effective cash tax rate to a level comparable to that seen in 2021.
