The financial performance between 2017 and 2021 is characterized by a period of moderate volatility followed by a significant expansion in profitability in the final year. While margins remained relatively stable or slightly contracted from 2019 to 2020, a substantial increase in operational efficiency and pricing power is evident in 2021.

Gross Profitability and Cost Management
The Cost of Goods Sold (COGS) maintained a range between 80.35% and 85.37% of net sales from 2017 through 2020. However, a sharp decline to 70.87% occurred in 2021, resulting in the gross profit margin peaking at 29.13%. This represents a significant departure from the 14% to 20% range observed in previous years, indicating a substantial reduction in production costs relative to sales revenue.
Operating Efficiency
Selling, general, and administrative expenses remained consistently low, fluctuating between 3.50% and 4.97% of net sales. This stability in overhead, combined with the reduction in COGS, led to a surge in operating income, which rose from 8.82% in 2020 to 23.36% in 2021. Profit sharing expenses also showed an increase in 2021, reaching 2.11% of net sales, reflecting the stronger operational performance.
Financial Costs and Tax Impact
Interest expense as a percentage of net sales demonstrated a consistent downward trend, decreasing from 1.41% in 2017 to 0.31% in 2021. This suggests an improvement in debt coverage or a reduction in relative leverage. Income tax expense as a percentage of sales peaked in 2021 at 5.23%, correlating with the higher pre-tax income levels of that year.
Net Income Trends
Net income attributable to the company experienced a decline from a high of 10.64% in 2018 to a low of 5.74% in 2020. This trend was reversed aggressively in 2021, with the net income margin climbing to 17.46%. This growth was primarily driven by the expansion of the gross margin rather than reductions in operating expenses.
Revenue Composition
A shift in the source of net sales is observable. Sales to related parties dropped from 1.83% in 2017 to a range of 0.13% to 0.17% from 2018 onward, indicating a transition toward near-total reliance on unrelated third-party customers.
