The financial performance, as measured by economic profit, demonstrates a generally positive trend over the five-year period. Net operating profit after taxes (NOPAT) increased significantly from 2020 to 2022, experienced a slight decrease in 2023, and then increased again in 2024. Invested capital also exhibited consistent growth throughout the period. The cost of capital remained constant, allowing for a clear assessment of economic profit generation.

NOPAT Trend
NOPAT increased from US$160.282 million in 2020 to US$248.394 million in 2021, representing a substantial growth rate. This growth continued into 2022, reaching US$416.610 million. A minor decline to US$409.452 million was observed in 2023, followed by a recovery to US$456.676 million in 2024, establishing a new peak.
Invested Capital Trend
Invested capital showed consistent growth throughout the period. Starting at US$635.280 million in 2020, it increased to US$683.433 million in 2021. The most significant increase occurred between 2021 and 2022, reaching US$1,231.421 million. Further growth was observed in 2023 (US$1,475.541 million) and 2024 (US$1,689.877 million), indicating continued investment in the business.
Economic Profit Trend
Economic profit mirrored the NOPAT trend, increasing from US$48.261 million in 2020 to US$127.893 million in 2021. The largest absolute increase in economic profit occurred between 2021 and 2022, reaching US$199.468 million. A decrease to US$149.271 million was noted in 2023, but economic profit recovered to US$158.775 million in 2024. This suggests the company consistently generated returns exceeding its cost of capital, although the rate of return experienced some fluctuation.

The consistent cost of capital simplifies the interpretation of economic profit. The increases in both NOPAT and invested capital contributed to the overall positive trend in economic profit. The slight dip in 2023 warrants further investigation to understand the underlying factors contributing to the temporary decrease in profitability, but the subsequent recovery in 2024 suggests this was not a systemic issue.

Net income
The net income shows a strong upward trend from 2020 to 2024. Starting at 164,375 thousand US dollars in 2020, it increased significantly to 242,023 thousand in 2021, and then nearly doubled to 437,672 thousand in 2022. A slight decline occurred in 2023 to 427,374 thousand, followed by a substantial jump to 1,786,700 thousand in 2024. This indicates not only robust growth but also notable volatility, especially the sharp rise in 2024.
Net operating profit after taxes (NOPAT)
The NOPAT exhibits generally consistent growth with a slight dip in the trend in 2023. The value increased from 160,282 thousand in 2020 to 248,394 thousand in 2021, then further to 416,610 thousand in 2022. It decreased marginally to 409,452 thousand in 2023, before increasing again to 456,676 thousand in 2024. While growth is evident, the increase is more moderate compared to net income, especially in the latest year.
Comparative insights
When comparing net income and NOPAT, net income shows higher volatility and more pronounced growth, particularly in 2024, whereas NOPAT demonstrates steadier progress with less sharp fluctuations. The divergence suggests factors impacting net income beyond operating profitability, such as non-operating income or expenses, might be significantly influencing results in the latest period.

The financial data reveals notable fluctuations in the income tax-related expenses over the five-year period. The net income tax expense shows a general upward trend from 2020 through 2022, rising from 4,967 thousand US dollars in 2020 to 87,265 thousand US dollars in 2022. However, this is followed by a decline to 78,467 thousand US dollars in 2023 and a significant reversal to a net benefit of -1,213,788 thousand US dollars in 2024, indicating a substantial tax benefit or credit in the latter year.

In contrast, cash operating taxes exhibit a different pattern. From 2020 to 2022, there is a marked increase from 4,486 thousand US dollars to 97,226 thousand US dollars. This is followed by a decrease to 66,188 thousand US dollars in 2023, after which cash operating taxes rise again to 78,589 thousand US dollars in 2024. Unlike the net income tax expense, cash operating taxes remain positive throughout the period, indicating consistent cash outflows related to tax payments.

The divergence between net income tax expense and cash operating taxes, especially evident in 2024, suggests significant non-cash tax adjustments or deferred tax impacts during that year. The large negative net income tax expense implies tax benefits recognized on the income statement that do not correspond to actual cash tax payments, as cash operating taxes remain positive. This could be indicative of tax credits, deferred tax assets, or other tax planning effects influencing the reporting of tax expenses.

Total reported debt & leases
The total reported debt and lease obligations exhibited fluctuations over the five-year period. The amount increased from 3,099 thousand USD at the end of 2020 to 5,807 thousand USD by the end of 2021, indicating a notable rise. This was followed by a decline to 3,797 thousand USD in 2022. Subsequently, debt levels increased again, reaching 7,868 thousand USD in 2023 and significantly rising to 15,793 thousand USD by the end of 2024. Overall, the trend shows increasing leverage with intermittent reductions.
Stockholders’ equity
Stockholders' equity demonstrated consistent and strong growth throughout the observed period. Starting at 966,587 thousand USD in 2020, equity increased steadily each year: reaching 1,243,985 thousand USD in 2021, 1,668,602 thousand USD in 2022, 2,049,939 thousand USD in 2023, and culminating at 3,145,767 thousand USD in 2024. This upward trend reflects ongoing accumulation of retained earnings or equity injections, contributing to a stronger capital base.
Invested capital
Invested capital showed a generally increasing pattern as well, though with more variability compared to equity. The value started at 635,280 thousand USD in 2020 and grew modestly to 683,433 thousand USD in 2021. Between 2021 and 2022, invested capital nearly doubled to 1,231,421 thousand USD, indicating significant capital deployment or acquisition. Growth continued in the following years but at a slower pace, reaching 1,475,541 thousand USD by 2023 and 1,689,877 thousand USD in 2024. This suggests progressive expansion of the company's capital assets or operational investment over time.

The economic spread ratio demonstrates a fluctuating pattern over the five-year period. Initially, a substantial increase is observed, followed by a period of decline and stabilization.

Economic Spread Ratio Trend
In 2020, the economic spread ratio stood at 7.60%. This figure experienced a significant rise to 18.71% in 2021, indicating a considerable improvement in the company’s ability to generate returns exceeding its cost of capital. The ratio subsequently decreased to 16.20% in 2022, suggesting a moderation in the rate of return generation. A more pronounced decline occurred in 2023, with the ratio falling to 10.12%. This downward trend continued into 2024, albeit at a slower pace, with the ratio reaching 9.40%.

The economic spread ratio’s peak in 2021 coincided with a substantial increase in economic profit. However, despite continued growth in economic profit from 2022 to 2024, the economic spread ratio decreased, indicating that invested capital was growing at a faster rate than economic profit.

Relationship with Economic Profit and Invested Capital
Economic profit increased consistently from 2020 to 2022, but experienced a decrease in 2023 before recovering slightly in 2024. Invested capital exhibited a steady upward trend throughout the entire period, with a particularly large increase between 2021 and 2022. The combination of increasing invested capital and a fluctuating economic profit appears to be the primary driver of the observed trend in the economic spread ratio.

The stabilization of the economic spread ratio around 9-10% in the most recent two years suggests a potential leveling off of the company’s ability to generate excess returns relative to its invested capital, given the current capital structure and operational efficiency.

The economic profit exhibited a generally positive trajectory between 2020 and 2023, followed by a moderate increase in the most recent period. Revenue demonstrated consistent growth throughout the observed timeframe. The economic profit margin, however, reveals a more nuanced pattern, peaking in 2022 before experiencing a decline.

Economic Profit
Economic profit increased significantly from $48.261 million in 2020 to $127.893 million in 2021, representing substantial growth. This upward trend continued into 2022, reaching $199.468 million. A decrease was noted in 2023, with economic profit falling to $149.271 million, but it partially recovered in 2024 to $158.775 million. While the 2023 decline is notable, the 2024 figure suggests a potential stabilization.
Revenue
Revenue consistently increased year-over-year. From $844.452 million in 2020, revenue grew to $1.207.798 million in 2021, then to $1.794.148 million in 2022. The rate of growth slowed slightly in 2023, with revenue reaching $1.821.072 million, but accelerated again in 2024 to $2.207.100 million. This indicates sustained demand for the company’s products or services.
Economic Profit Margin
The economic profit margin increased from 5.72% in 2020 to 10.59% in 2021, reflecting improved profitability relative to revenue. The margin continued to rise, reaching a peak of 11.12% in 2022. However, a decline was observed in 2023, with the margin falling to 8.20%. This downward trend persisted into 2024, with the margin decreasing further to 7.19%. The decrease in margin, despite continued revenue growth, suggests increasing costs or pricing pressures impacting profitability.

The divergence between revenue growth and economic profit margin in the later periods warrants further investigation. While the company is generating more revenue, a smaller proportion of that revenue is translating into economic profit. This could be due to increased operating expenses, higher costs of goods sold, or changes in the competitive landscape.
