The profit margins across reportable segments demonstrated substantial volatility over the five-year period ending December 31, 2023. Both the Modules Business and the Other segment experienced a synchronized margin compression in 2022, followed by an aggressive expansion in 2023.

Modules Business Profit Margin
The Modules Business maintained relatively stable margins between 19.87% and 24.72% from 2019 through 2021. A significant contraction occurred in 2022, with margins falling to 4.75%, the lowest level observed in the period. This was followed by a sharp recovery in 2023, where the margin reached a period high of 38.75%.
Other Segment Profit Margin
The Other segment exhibited more extreme fluctuations than the core modules business. After a steady upward trend from 16.17% in 2019 to 43.42% in 2021, the segment shifted to a negative margin of -23.84% in 2022. In 2023, this segment saw an anomalous surge to 106.72%, suggesting highly irregular profitability drivers within this category.

1 2023 Calculation
Segment profit margin = 100 × Gross profit (loss) ÷ Net sales
= 100 × 1,277,421 ÷ 3,296,809 = 38.75%


The Modules Business exhibited consistent revenue growth over the five-year period from 2019 to 2023, although profitability experienced significant volatility, particularly between 2021 and 2023.

Net Sales Trend
Net sales demonstrated a continuous upward trajectory, increasing from US$ 1.46 billion in 2019 to US$ 3.30 billion in 2023. The most substantial year-over-year growth occurred in 2023, where sales expanded by approximately 35% compared to the previous year.
Gross Profit Volatility
Gross profit did not follow the linear growth of net sales. While profits rose steadily from 2019 to 2021, a sharp contraction occurred in 2022, with gross profit falling to US$ 115.39 million. This was followed by an exponential increase in 2023, reaching a period high of US$ 1.28 billion, representing a more than ten-fold increase from the 2022 low.
Segment Profit Margin Analysis
The segment profit margin reflected high variability. After peaking at 24.72% in 2020, the margin contracted to 20.29% in 2021 and collapsed to 4.75% in 2022, indicating a period of severe margin compression despite rising sales. However, 2023 marked a significant recovery and expansion, with the profit margin surging to 38.75%, the highest level recorded in the analyzed timeframe.

The divergence between sales and profit in 2022 suggests a period of increased cost of goods sold or pricing pressures that temporarily eroded profitability. The subsequent surge in 2023 indicates a successful realignment of cost structures or a significant increase in average selling prices, resulting in record-level operational efficiency for the Modules Business.

1 2023 Calculation
Segment profit margin = 100 × Gross profit (loss) ÷ Net sales
= 100 × 23,258 ÷ 21,793 = 106.72%


The "Other" reportable segment has experienced a severe and consistent contraction in net sales over the five-year period ending December 31, 2023. Revenue declined from $1,603,001 thousand in 2019 to $21,793 thousand in 2023, representing a near-total erosion of the segment's sales base.

Revenue and Profitability Trends (2019–2021)
During the initial three-year period, a divergence is observed between net sales and segment profit margins. While net sales fell from $1,603,001 thousand to $591,997 thousand, the segment profit margin expanded significantly, rising from 16.17% in 2019 to 43.42% in 2021. This suggests that despite the reduction in scale, the segment maintained strong gross profit levels, which remained relatively stable between $251 million and $259 million.
Operational Downturn (2022)
The year 2022 marked a sharp transition into negative profitability. Gross profit shifted to a loss of $45,539 thousand, resulting in a negative segment profit margin of -23.84%. This coincides with a continued decline in net sales, which dropped to $191,041 thousand, indicating a period of significant operational instability or the realization of substantial losses within the segment.
Margin Anomaly (2023)
In 2023, the segment reported a gross profit of $23,258 thousand against net sales of only $21,793 thousand. This resulted in a segment profit margin of 106.72%. The fact that gross profit exceeded net sales suggests the presence of non-standard accounting adjustments, credits, or other income recognized within the gross profit calculation that outweighs the actual sales generated during the period.

Net sales exhibit a profound structural shift in revenue composition between 2019 and 2023. The overall revenue trajectory is characterized by a transition from a diversified revenue base toward a near-total reliance on a single reportable segment, resulting in an overall increase in total net sales by the conclusion of the period.

Modules Business Performance
A consistent upward trend is observed in the Modules Business, with net sales increasing from US$ 1,460,116 thousand in 2019 to US$ 3,296,809 thousand in 2023. This represents a continuous growth trajectory, with the most significant year-over-year expansion occurring between 2022 and 2023, where revenue increased by approximately 35%.
Other Segment Contraction
The segment categorized as Other has experienced a precipitous and uninterrupted decline. Starting at US$ 1,603,001 thousand in 2019, revenues in this category fell to US$ 21,793 thousand by 2023. This contraction indicates a systemic phase-out of non-module related revenue streams, effectively reducing this segment's contribution to total net sales from approximately 52% in 2019 to less than 1% in 2023.
Total Net Sales Dynamics
Total net sales remained volatile but fluctuated within a range of US$ 2.6 billion to US$ 3.3 billion throughout the five-year period. While total revenue experienced declines in 2020 and 2022, the accelerated expansion of the Modules Business eventually offset the losses from the Other segment, culminating in a period high of US$ 3,318,602 thousand in 2023.

Total gross profit exhibited a period of steady growth from 2019 through 2021, followed by a severe contraction in 2022 and a substantial recovery in 2023. The overall financial performance is heavily driven by the Modules Business segment, which has transitioned from a primary contributor to the overwhelming driver of gross profitability.

Modules Business Performance
Gross profit within the Modules Business grew incrementally from US$ 290.1 million in 2019 to US$ 472.9 million in 2021. A sharp decline was observed in 2022, where profit fell to US$ 115.4 million. This was followed by an explosive increase in 2023, with gross profit reaching US$ 1.28 billion, representing a significant expansion in the segment's earnings capacity.
Other Segment Analysis
The Other segment demonstrated relative stability between 2019 and 2021, with gross profits remaining consistent around the US$ 250 million to US$ 260 million range. A critical reversal occurred in 2022, resulting in a gross loss of US$ 45.5 million. Although the segment returned to a positive balance in 2023, the profit of US$ 23.3 million is substantially lower than the levels maintained prior to 2022.
Aggregate Profitability Trends
Total gross profit peaked at US$ 1.3 billion in 2023, reflecting a massive recovery from the 2022 low of US$ 69.9 million. The data indicates a shift in the company's profit structure; while the Other segment provided nearly half of the total gross profit in 2019, the Modules Business accounted for approximately 98% of total gross profit by the end of 2023.
