Economic profit = NOPAT – Cost of capital × Invested capital
= 456,676 – 17.69% × 1,689,877 = 157,724


The financial trajectory between 2020 and 2024 indicates a period of aggressive operational expansion and substantial growth in net profitability, although the efficiency of value creation relative to invested capital has experienced volatility.

Net Operating Profit After Taxes (NOPAT)
A consistent upward trend is observed in NOPAT, which grew from US$ 160.3 million in 2020 to US$ 456.7 million by 2024. This expansion signifies a strong increase in the company's capacity to generate after-tax operating income from its core business activities over the five-year period.
Invested Capital and Cost of Capital
Invested capital expanded significantly, rising from US$ 635.3 million in 2020 to US$ 1.69 billion in 2024. The most pronounced increase occurred between 2021 and 2022. Throughout this period of capital growth, the cost of capital remained remarkably stable, fluctuating minimally around 17.7%, indicating a consistent risk profile and cost of funding.
Economic Profit Dynamics
Economic profit demonstrated a sharp increase from 2020 to 2022, peaking at US$ 198.7 million. However, a decline was recorded in 2023, with economic profit falling to US$ 148.4 million. This contraction is attributable to a slight decrease in NOPAT during that year coupled with a continued increase in the invested capital base, which raised the overall capital charge. A modest recovery occurred in 2024, with economic profit rising to US$ 157.7 million.

8 Elimination of after taxes investment income.


The financial performance from 2020 through 2024 indicates a general trajectory of growth in both net income and net operating profit after taxes (NOPAT), although a significant divergence between these two metrics occurred in the final reporting period.

Net Income Trends
Net income exhibited consistent growth from 2020 to 2022, increasing from 164,375 thousand to 437,672 thousand. After a marginal decline in 2023 to 427,374 thousand, a substantial surge is observed in 2024, where net income reached 1,786,700 thousand, representing an increase of approximately 318% over the previous year.
NOPAT Progression
The net operating profit after taxes followed a similar growth pattern to net income between 2020 and 2022, rising from 160,282 thousand to 416,610 thousand. In 2023, NOPAT experienced a slight contraction to 409,452 thousand, followed by a moderate increase to 456,676 thousand in 2024.
Operating vs. Non-Operating Divergence
A notable correlation existed between net income and NOPAT from 2020 to 2023, suggesting that earnings were primarily driven by core operations. However, in 2024, a sharp decoupling is evident. While net income grew exponentially, NOPAT increased by only 11.5% relative to 2023. This disparity indicates that the vast majority of the 2024 net income increase was derived from non-operating sources rather than core operational profitability.
Implications for Economic Value Added
Because EVA is calculated based on NOPAT, the core operational contribution to economic value grew at a much slower rate in 2024 than the net income figure suggests. The stability of NOPAT relative to the volatility of net income in the final period suggests that the underlying operational efficiency remained steady, while the bottom line was influenced by extraordinary non-operating items.

The financial trajectory of tax obligations reveals a period of significant growth in cash outflows followed by a stark divergence between accounting tax expenses and actual cash tax payments in the final year of the analyzed period.

Cash Operating Tax Trends
Cash operating taxes exhibited a steep upward trajectory from 2020 through 2022, increasing from 4,486 thousand US$ to a peak of 97,226 thousand US$. A subsequent contraction occurred in 2023, with payments decreasing to 66,188 thousand US$, before recovering to 78,589 thousand US$ in 2024.
Accounting vs. Cash Tax Divergence
A significant anomaly is observed in 2024. While the income tax expense (benefit), net, recorded a massive benefit of -1,213,788 thousand US$, the cash operating taxes remained a positive outflow of 78,589 thousand US$. This indicates that the reported tax benefit was entirely non-cash, likely resulting from deferred tax asset adjustments or accounting-based tax credits that did not translate into immediate cash inflows or a reduction in current tax payments.
Impact on Economic Value Added (EVA)
The utilization of cash operating taxes rather than net income tax expense in the context of EVA prevents the artificial inflation of economic profit for the 2024 period. By focusing on the actual cash outflow of 78,589 thousand US$ instead of the reported accounting benefit, the analysis maintains a realistic view of the company's after-tax cash operating profit and its ability to cover the cost of capital.

The analysis of the capital structure from 2020 through 2024 reveals a consistent expansion of the resource base used to generate economic value. A strong upward trajectory is observed across all primary capital metrics, characterized by substantial growth in stockholders' equity and a steady increase in invested capital.

Invested Capital Growth
Invested capital has demonstrated a continuous increase over the five-year period, rising from 635,280 thousand US dollars in 2020 to 1,689,877 thousand US dollars by 2024. This represents a total increase of approximately 166%. A significant acceleration occurred between 2021 and 2022, where invested capital grew by approximately 80%, suggesting a period of intensified capital deployment or asset acquisition.
Stockholders' Equity Expansion
Stockholders' equity has grown steadily and substantially each year, increasing from 966,587 thousand US dollars in 2020 to 3,145,767 thousand US dollars in 2024. The consistent growth in equity indicates strong retained earnings or capital injections, providing a robust cushion for operations and future investments.
Debt and Leverage Profile
Total reported debt and leases remain negligible relative to the total equity and invested capital. While debt increased from 3,099 thousand US dollars in 2020 to 15,793 thousand US dollars in 2024, the leverage ratio remains extremely low. The jump in debt observed in 2024 does not materially alter the company's low-leverage financial profile.
Capital Composition Insights
A notable divergence is observed between stockholders' equity and invested capital. By 2024, stockholders' equity exceeded invested capital by over 1.4 billion US dollars. This indicates a high concentration of non-operating assets, such as cash and short-term investments, which are excluded from the invested capital calculation in an Economic Value Added (EVA) framework.

The financial trajectory between 2020 and 2024 is characterized by a substantial expansion of the capital base accompanied by fluctuating economic profits and a peaking then declining economic spread ratio.

Economic Profit Trends
Economic profit experienced rapid growth in the early part of the period, rising from 47.87 million USD in 2020 to a peak of 198.70 million USD in 2022. Following this peak, a contraction occurred in 2023 to 148.35 million USD, followed by a modest recovery to 157.72 million USD by the end of 2024.
Invested Capital Expansion
Invested capital exhibited a consistent and aggressive upward trajectory throughout the five-year period. The capital base grew from 635.28 million USD in 2020 to 1.69 billion USD in 2024, indicating a significant increase in the resources deployed to support operations and growth.
Economic Spread Ratio Analysis
The economic spread ratio demonstrated a sharp initial increase from 7.53% in 2020 to a peak of 18.65% in 2021. A persistent downward trend followed, with the ratio declining to 16.14% in 2022, 10.05% in 2023, and 9.33% in 2024. This decline suggests that the growth in invested capital has outpaced the growth in economic profit, resulting in a reduction of the value created per unit of capital employed.

The financial performance from 2020 to 2024 is characterized by consistent revenue expansion contrasted with a fluctuating economic profit trajectory and a declining economic profit margin after 2022. While the absolute value of economic profit remains significantly higher than 2020 levels, the efficiency of value creation relative to sales has diminished in the most recent two fiscal years.

Revenue Growth Trends
A sustained upward trajectory in revenue is observed throughout the period, increasing from 844,452 thousand US dollars in 2020 to 2,207,100 thousand US dollars by 2024. This represents a continuous expansion of the top line, with the most significant growth occurring between 2020 and 2022.
Economic Profit Analysis
Economic profit experienced rapid growth in the early part of the period, peaking at 198,702 thousand US dollars in 2022. A correction occurred in 2023, where profit fell to 148,353 thousand US dollars, followed by a modest recovery to 157,724 thousand US dollars in 2024. Despite this volatility, the 2024 economic profit remains more than triple the amount recorded in 2020.
Economic Profit Margin Evolution
The economic profit margin demonstrates a bell-shaped trend. After starting at 5.67% in 2020, the margin climbed sharply to a peak of 11.08% in 2022. However, a downward trend is evident in the subsequent years, with the margin contracting to 8.15% in 2023 and further declining to 7.15% in 2024. This divergence suggests that revenue growth is currently outpacing the growth of economic profit, indicating a decrease in the efficiency of capital utilization relative to sales volume.
