Based on: 10-K (reporting date: 2022-12-31), 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31).


The overall trajectory of goodwill and intangible assets indicates a period of significant expansion from 2018 through 2021, followed by a slight contraction in 2022. Total combined assets grew from approximately 1.9 billion US dollars in 2018 to a peak of 2.76 billion US dollars in 2021, before declining to 2.64 billion US dollars by the end of 2022.

Goodwill Trends
Goodwill experienced a consistent upward trend between 2018 and 2021, increasing from 1.61 billion US dollars to 2.32 billion US dollars. This growth suggests an active acquisition strategy during this four-year window. The value remained relatively stable into 2022, ending at 2.31 billion US dollars, indicating a cessation of large-scale acquisitive growth or a period of stability in the valuation of acquired entities.
Intangible Asset Composition
Gross intangible assets peaked in 2020 at 926.7 million US dollars before declining to 752 million US dollars by 2022. A notable volatility is observed in acquired technology and data, which rose to 131.6 million US dollars in 2020 but fell sharply to 42 million US dollars by 2021, suggesting significant impairment or accelerated amortization of specific technological assets. Similarly, the acquired customer base grew steadily from 339.6 million US dollars in 2018 to a peak of 569.7 million US dollars in 2021, before retreating to 464.2 million US dollars in 2022.
Amortization and Net Valuation
Accumulated amortization increased steadily from 2018 to 2020, reaching 499.9 million US dollars. However, a reversal occurred in 2021 and 2022, where the accumulated amortization balance decreased to 422.7 million US dollars. This reduction, coinciding with the decrease in gross intangible assets, typically indicates the write-off of fully amortized assets or impairment charges. Consequently, net intangible assets reached a peak of 435.7 million US dollars in 2021 before dropping significantly to 329.3 million US dollars in 2022.

In summary, the financial profile reflects a transition from a growth-oriented acquisition phase (2018-2021) to a phase of asset normalization and potential impairment in 2022. While goodwill remains the dominant component of the balance sheet, the volatility within the acquired technology and customer base segments highlights a shifting valuation of intangible drivers.

The financial data reflects a sustained expansion in both reported and adjusted asset bases and stockholders' equity from 2018 to 2022. The removal of goodwill and intangible assets reveals a significant portion of the balance sheet is composed of non-tangible items, though the relative proportion of tangible assets increased over the five-year period.

Asset Composition Trends
Reported total assets increased from 3,312,957 thousand US$ in 2018 to 8,402,470 thousand US$ in 2022. Concurrently, adjusted total assets rose from 1,701,422 thousand US$ to 6,087,711 thousand US$. The gap between these two figures, representing goodwill and intangible assets, grew from approximately 1.61 billion US$ in 2018 to 2.31 billion US$ in 2022. Notably, adjusted assets as a percentage of reported assets grew from 51.4% in 2018 to 72.5% in 2022, indicating a shift toward a higher concentration of tangible or identifiable assets.
Equity Value Adjustments
A similar pattern is observed in stockholders' equity. Reported equity grew from 3,021,942 thousand US$ in 2018 to 6,870,121 thousand US$ in 2022. When adjusted for the removal of goodwill and intangibles, equity figures rose from 1,410,407 thousand US$ to 4,555,362 thousand US$. The adjusted equity grew at a faster relative rate than reported equity, suggesting that the increase in net worth is increasingly driven by operational growth and retained earnings rather than the acquisition of intangible assets.
Comparative Growth Analysis
The growth rate of adjusted assets significantly outperformed the growth rate of reported assets over the analyzed period. While reported assets increased by approximately 154%, adjusted assets increased by approximately 258%. This divergence indicates that the company's balance sheet expansion was primarily fueled by the growth of tangible assets and operational scaling rather than an increasing reliance on goodwill associated with acquisitions.

The exclusion of goodwill and intangible assets from the financial analysis reveals a significant divergence between reported performance metrics and the underlying efficiency of the tangible asset base. Across all measured periods from 2018 to 2022, adjusted ratios consistently demonstrate higher operational efficiency and profitability, albeit with an increase in perceived financial risk.

Asset Utilization and Turnover
A substantial increase is observed in total asset turnover when goodwill is removed. In 2018 and 2019, the adjusted turnover ratio was nearly double the reported figures, rising from 0.36 to 0.70 and 0.36 to 0.71, respectively. While both reported and adjusted metrics experienced a sharp decline in 2020, the adjusted ratio remained consistently higher, indicating that the company's tangible assets generate significantly more revenue than the total asset base suggests.
Financial Leverage
The removal of intangible assets results in a consistent increase in financial leverage. Reported leverage peaked in 2020 at 1.29, while the adjusted leverage for the same period reached 1.49. This upward shift across all five years indicates that the company's debt burden is more pronounced when measured against its tangible net worth, suggesting a higher reliance on leverage relative to physical assets.
Return on Equity (ROE)
Adjusted ROE figures exhibit a marked amplification compared to reported values. Between 2018 and 2019, adjusted ROE climbed from 16.90% to 20.67%, whereas reported ROE only reached 9.25% in 2019. Despite a significant contraction in 2020, the adjusted ROE remained superior to the reported ROE throughout the period, illustrating that the reported returns are heavily diluted by the large book value of intangible assets.
Return on Assets (ROA)
A similar pattern is evident in the return on assets. The adjusted ROA was approximately double the reported ROA in the early period, peaking at 15.97% in 2019 compared to a reported 8.17%. Although the 2020 downturn affected both metrics, the adjusted ROA maintained a higher trajectory, ending at 6.07% in 2022 against a reported 4.40%, confirming that the tangible asset base is more productive in generating earnings than the total reported asset base.

Overall, the data indicates that while the reported figures provide a conservative view of profitability and efficiency, they obscure the high productivity of the company's core tangible assets. Conversely, the adjusted ratios highlight a more leveraged financial structure that accompanies this operational efficiency.

2022 Calculations

1 Total asset turnover = Revenues ÷ Total assets
= 2,182,399 ÷ 8,402,470 = 0.26

2 Adjusted total asset turnover = Revenues ÷ Adjusted total assets
= 2,182,399 ÷ 6,087,711 = 0.36


A comprehensive analysis of the asset base and utilization efficiency reveals a significant expansion in both reported and adjusted total assets between 2018 and 2022. Reported total assets grew from US$ 3.31 billion to US$ 8.40 billion, while adjusted total assets increased from US$ 1.70 billion to US$ 6.09 billion. The persistent gap between these two figures indicates a substantial presence of goodwill and intangible assets, which significantly influences the interpretation of asset productivity.

Asset Growth Patterns
The asset base experienced a steady upward trajectory, with a pronounced acceleration occurring in 2020. Reported assets increased by approximately 78% between 2019 and 2020, while adjusted assets grew by approximately 137% in the same timeframe. This suggests that while the overall balance sheet expanded, the growth in operational assets was even more aggressive during this specific inflection point.
Comparative Analysis of Asset Turnover
Adjusted total asset turnover consistently remained higher than reported total asset turnover across all five years. In 2018 and 2019, the adjusted ratio was nearly double the reported ratio, indicating that the exclusion of goodwill and intangible assets reveals a significantly higher level of efficiency in the company's core operational assets. This disparity underscores the heavy weighting of intangible assets within the reported total asset figure.
Turnover Efficiency Trends
A sharp decline in asset utilization efficiency is observed starting in 2020. The adjusted total asset turnover dropped from 0.71 in 2019 to 0.35 in 2020, representing a reduction of over 50%. While a marginal recovery to 0.39 was noted in 2021, the ratio settled at 0.36 by 2022. This trend suggests that the rapid expansion of the asset base between 2019 and 2020 has not been matched by a corresponding increase in revenue generation, leading to lower overall productivity per dollar of adjusted assets compared to the 2018-2019 period.

2022 Calculations

1 Financial leverage = Total assets ÷ Stockholders’ equity
= 8,402,470 ÷ 6,870,121 = 1.22

2 Adjusted financial leverage = Adjusted total assets ÷ Adjusted stockholders’ equity
= 6,087,711 ÷ 4,555,362 = 1.34


The balance sheet exhibits a sustained growth trend in both total assets and stockholders' equity over the five-year period. A substantial divergence is observed between reported and adjusted figures, indicating that intangible assets and goodwill constitute a material portion of the total asset base and equity.

Asset and Equity Composition
Reported total assets increased from US$ 3,312,957 thousand in 2018 to US$ 8,402,470 thousand in 2022. During the same period, adjusted total assets—which exclude goodwill and intangible assets—grew from US$ 1,701,422 thousand to US$ 6,087,711 thousand. This persistent gap confirms that a significant percentage of the company's growth is tied to non-physical assets. Adjusted stockholders' equity followed a similar pattern, growing from US$ 1,410,407 thousand to US$ 4,555,362 thousand, remaining consistently lower than reported equity.
Reported vs. Adjusted Financial Leverage
Adjusted financial leverage is consistently higher than reported financial leverage across the entire observation period. This suggests that when intangible assets are removed from the calculation, the company's financial leverage appears more elevated, reflecting a higher reliance on debt or other liabilities relative to tangible equity.
Leverage Trend Analysis
Both leverage metrics peaked in 2020, with reported leverage reaching 1.29 and adjusted leverage reaching 1.49. Following this peak, a downward trend is observed through 2022, with reported leverage decreasing to 1.22 and adjusted leverage decreasing to 1.34. This trend indicates a gradual reduction in financial risk and a strengthening of the equity position relative to total assets.

The analysis reveals that while the company has scaled its assets and equity significantly, the reliance on intangible assets creates a discrepancy between reported and adjusted leverage. The reduction in leverage since 2020 suggests a transition toward a more conservative financial posture, although the adjusted leverage remains the more conservative indicator of solvency.

2022 Calculations

1 ROE = 100 × Net income ÷ Stockholders’ equity
= 100 × 369,453 ÷ 6,870,121 = 5.38%

2 Adjusted ROE = 100 × Net income ÷ Adjusted stockholders’ equity
= 100 × 369,453 ÷ 4,555,362 = 8.11%


The financial performance from 2018 to 2022 demonstrates a consistent expansion of the capital base, characterized by a significant divergence between reported and adjusted equity metrics. This variance indicates a substantial concentration of goodwill and intangible assets within the company's balance sheet.

Equity Trends and Composition
Reported stockholders' equity grew from $3.02 billion in 2018 to $6.87 billion in 2022. Concurrently, adjusted stockholders' equity increased from $1.41 billion to $4.56 billion. The fact that adjusted equity remains consistently and significantly lower than reported equity confirms that a large proportion of the equity base is comprised of non-tangible assets.
Analysis of Return on Equity (ROE)
A persistent gap is observed between reported ROE and adjusted ROE across the entire five-year period. Adjusted ROE consistently outperforms reported ROE, reaching a peak of 20.67% in 2019 compared to a reported 9.25% in the same year. This suggests that when the influence of goodwill and intangible assets is removed, the return on the actual invested tangible capital is considerably higher.
Performance Fluctuations and Stabilization
A sharp decline in efficiency occurred in 2020, where adjusted ROE dropped to 7.23% from its 2019 high. Following this contraction, a period of relative stabilization is observed, with adjusted ROE recording 8.63% in 2021 and 8.11% in 2022. While the reported ROE remained low and relatively flat between 2020 and 2022 (ranging from 4.23% to 5.38%), the adjusted ROE provides a more optimistic view of the core operational profitability.

= 100 × 369,453 ÷ 6,087,711 = 6.07%


An analysis of the financial data from 2018 to 2022 reveals a consistent expansion of the asset base and a significant divergence between reported and adjusted performance metrics. The most notable volatility occurs around the 2020 fiscal year, marking a pivot in the company's asset structure and subsequent return profiles.

Asset Base Expansion
Reported total assets grew from US$ 3.31 billion in 2018 to US$ 8.40 billion in 2022. A substantial increase is observed between 2019 and 2020, where total assets rose by approximately 79%. Adjusted total assets, which exclude goodwill and intangible assets, followed a similar growth trajectory, increasing from US$ 1.70 billion to US$ 6.09 billion over the same period. The gap between reported and adjusted assets indicates a significant presence of intangible assets, although the proportion of these assets relative to the total balance sheet decreased from 2018 to 2022.
Return on Assets (ROA) Trends
Reported ROA experienced a peak of 8.17% in 2019 before declining sharply to 3.28% in 2020. While a gradual recovery is observed through 2022, reaching 4.40%, the figures remain well below the pre-2020 levels. Adjusted ROA mirrors this pattern but maintains consistently higher values, peaking at 15.97% in 2019 before dropping to 4.85% in 2020 and recovering to 6.07% by 2022.
Impact of Intangible Asset Adjustments
The variance between reported and adjusted ROA highlights the substantial impact of goodwill and intangible assets on profitability metrics. In 2018 and 2019, the adjusted ROA was approximately double the reported ROA, suggesting that a large portion of the asset base was non-operational or attributed to acquisitions. The convergence of these two metrics in 2020, 2021, and 2022 suggests that while the absolute value of intangible assets remained high, the growth in tangible, adjusted assets became a more dominant driver of the total asset composition.
Operational Efficiency Inflection
The precipitous drop in both reported and adjusted ROA in 2020 indicates a period where asset growth significantly outpaced income generation. The subsequent modest rise in ROA from 2020 to 2022 suggests a gradual improvement in the utilization of the expanded asset base, although the company has not yet returned to the high-efficiency levels observed in the 2018-2019 period.
