Based on: 10-K (reporting date: 2023-08-26), 10-K (reporting date: 2022-08-27), 10-K (reporting date: 2021-08-28), 10-K (reporting date: 2020-08-29), 10-K (reporting date: 2019-08-31), 10-K (reporting date: 2018-08-25).


A sustained upward trajectory is observed in both reported and adjusted net income from fiscal year 2018 through 2023. Total earnings expanded from approximately $1.34 billion to $2.53 billion over this period, reflecting a consistent growth pattern in profitability.

Earnings Growth Analysis
Reported net income exhibited steady annual increases, with a notable acceleration between 2020 and 2021. This growth trend is mirrored almost identically in the adjusted net income figures, indicating that the core drivers of profitability remained stable across the analyzed timeframe.
Evaluation of Mark-to-Market Adjustments
The adjustments related to the mark-to-market valuation of available-for-sale securities are immaterial in scale relative to total net income. The variance between reported and adjusted figures fluctuates minimally, ranging from a surplus in reported income in 2018 and 2021-2022 to a slight surplus in adjusted income in 2019, 2020, and 2023. The maximum deviation occurred in 2022, yet it represented a nominal fraction of the total net income, suggesting these investment adjustments do not significantly distort the overall financial performance.

Based on: 10-K (reporting date: 2023-08-26), 10-K (reporting date: 2022-08-27), 10-K (reporting date: 2021-08-28), 10-K (reporting date: 2020-08-29), 10-K (reporting date: 2019-08-31), 10-K (reporting date: 2018-08-25).


An analysis of the profitability and asset efficiency metrics from 2018 to 2023 indicates a general upward trend in net profit margins and a recovery in return on assets following a significant dip in 2020. The minimal variance between reported and adjusted figures suggests that mark-to-market adjustments for available-for-sale securities have an immaterial impact on the company's core financial performance.

Net Profit Margin Trends
The reported net profit margin exhibited consistent growth over a four-year period, rising from 11.92% in August 2018 to a peak of 14.95% in August 2022. A slight contraction occurred in the final period, with the margin settling at 14.48% in August 2023. The adjusted net profit margin closely mirrors this trajectory, maintaining a nearly identical trend line throughout the analysis period.
Return on Assets (ROA) Performance
ROA demonstrated higher volatility compared to profit margins. After reaching 16.34% in 2019, a sharp decline to 12.01% was observed in 2020. However, a robust recovery followed, with reported ROA climbing to 15.91% by 2022 before stabilizing at 15.82% in 2023. This indicates an improved efficiency in utilizing assets to generate earnings following the 2020 downturn.
Impact of Adjusted Mark-to-Market Securities
The delta between reported and adjusted ratios is negligible across all years. For both net profit margin and ROA, the adjustments typically result in variances of only 0.01% to 0.03%. This suggests that the valuation fluctuations of available-for-sale securities do not significantly distort the underlying profitability or the asset return profile of the organization.

2023 Calculations

1 Net profit margin = 100 × Net income ÷ Net sales
= 100 × 2,528,426 ÷ 17,457,209 = 14.48%

2 Adjusted net profit margin = 100 × Adjusted net income ÷ Net sales
= 100 × 2,528,746 ÷ 17,457,209 = 14.49%


An analysis of the financial performance from August 2018 to August 2023 reveals a period of sustained growth in absolute profitability, accompanied by a general expansion of profit margins that peaked in 2022 before experiencing a slight contraction in 2023.

Net Income Trajectory
Reported net income demonstrated a consistent upward trend, increasing from 1,337,536 thousand USD in 2018 to 2,528,426 thousand USD in 2023. Adjusted net income mirrored this growth almost exactly, indicating that non-recurring items or accounting adjustments had a negligible impact on the overall earnings trend throughout the six-year period.
Adjusted Net Profit Margin Expansion
The adjusted net profit margin rose steadily from 11.91% in 2018 to a peak of 14.93% in 2022. This consistent increase suggests an improvement in cost management or an increase in operational efficiency over those five years.
Recent Margin Correlation and Correction
A marginal decline in the adjusted net profit margin is observed in the final period, moving from 14.93% in 2022 to 14.49% in 2023. Despite this slight reduction, the margin remains 2.58 percentage points higher than the 2018 baseline, reflecting a long-term improvement in profitability levels.
Reported versus Adjusted Variance
A very high degree of convergence exists between reported and adjusted metrics. The variance between the reported and adjusted net profit margins remains minimal, typically fluctuating by only 0.01 to 0.02 percentage points, suggesting a stable earnings profile with few significant one-time financial distortions.

A consistent upward trajectory in profitability is observed from August 2018 through August 2023. Both reported and adjusted net income demonstrate steady annual growth, indicating a sustained increase in the company's earnings capacity over the six-year period.

Net Income Growth Trends
Reported net income increased from US$ 1,337,536 thousand in 2018 to US$ 2,528,426 thousand in 2023. Adjusted net income followed a nearly identical progression, rising from US$ 1,336,674 thousand to US$ 2,528,746 thousand during the same timeframe. The most significant year-over-year increase occurred between 2020 and 2021.
Analysis of Earnings Adjustments
A negligible variance exists between reported and adjusted net income across all recorded periods. This indicates that non-recurring items, extraordinary gains, or losses had a minimal impact on the company's bottom-line results.
Return on Equity (ROE) Assessment
While net income shows robust growth, the Adjusted ROE and Reported ROE cannot be evaluated as the specific percentage values and the underlying equity data are not present. Consequently, the efficiency of equity utilization cannot be quantified from the available information.

2023 Calculations

1 ROA = 100 × Net income ÷ Total assets
= 100 × 2,528,426 ÷ 15,985,878 = 15.82%

2 Adjusted ROA = 100 × Adjusted net income ÷ Total assets
= 100 × 2,528,746 ÷ 15,985,878 = 15.82%


The financial trajectory from August 2018 to August 2023 is characterized by a consistent increase in net income alongside a fluctuating but generally stable return on assets (ROA). While absolute earnings have grown significantly, the efficiency of asset utilization experienced a temporary contraction in 2020 before returning to levels consistent with the 2018-2019 period.

Net Income Growth Trends
Both reported and adjusted net income demonstrate a strong upward trend, increasing from approximately 1.34 billion USD in 2018 to approximately 2.53 billion USD in 2023. This represents an overall growth of approximately 89% over the observed period. The most substantial acceleration in growth occurred between 2020 and 2021, during which net income rose from 1.73 billion USD to 2.17 billion USD.
Adjusted Return on Assets (ROA) Performance
The Adjusted ROA exhibited a peak of 16.36% in 2019, followed by a decline to a six-year low of 12.02% in 2020. A recovery phase followed, with the ratio ascending to 14.94% in 2021 and 15.89% in 2022, before stabilizing at 15.82% in 2023. The fact that ROA remained relatively stable despite the near-doubling of net income suggests that the asset base expanded proportionally to the earnings growth.
Comparison of Reported and Adjusted Metrics
There is a negligible variance between reported and adjusted financial figures across all analyzed years. The Adjusted ROA deviates from the Reported ROA by no more than 0.02 percentage points in any given year. This convergence indicates that non-recurring items or accounting adjustments have had a minimal impact on the company's bottom line and its overall asset efficiency.
