The financial data indicates a period of significant margin expansion followed by a recent contraction in profitability. Over the majority of the analyzed timeframe, there is a consistent improvement in both gross and operating margins, suggesting enhanced operational efficiency or increased pricing power. This positive trajectory peaked in late 2024 and 2025 before a downturn was observed in the first quarter of 2026.

Gross Profitability and Cost Management
Gross profit margins demonstrated a steady upward trend, rising from 32.14% in March 2021 to a peak of 38.93% in December 2024. This improvement is directly correlated with a sustained reduction in the cost of products sold, which declined from 67.86% in early 2021 to a low of 61.07% by December 2024. However, a reversal occurred in early 2026, with the cost of products sold increasing to 64.41% and gross profit receding to 35.59%.
Operating Expense Trends
Selling and administrative expenses remained relatively range-bound, generally fluctuating between 14% and 17% of net sales. While there were periodic dips, such as the 14.30% observed in September 2025, the expense ratio returned to 17.03% by March 2026. Research and development expenses exhibited high stability throughout the period, consistently remaining between 2.73% and 3.41% of net sales, indicating a disciplined and steady investment in innovation regardless of revenue fluctuations.
Operating and Net Income Performance
Operating income margins showed an overall growth pattern, moving from 12.04% in March 2021 to 19.62% in December 2024. A significant non-recurring spike occurred in September 2021, where operating income reached 24.70% due to a one-time gain on the sale of a business totaling 12.53% of net sales. Net income attributable to ordinary shareholders mirrored this growth, climbing from 9.76% in early 2021 to a high of 16.03% in December 2025, before falling to 11.62% in March 2026.
Non-Operating Items and Taxation
Net interest expenses were generally maintained below 1% of net sales for most of the period, although a peak of 1.42% was reached in March 2026. Income tax expenses as a percentage of net sales remained volatile, with a notable peak of 9.81% in September 2021 coinciding with the gain on the sale of business. Other income and expenses remained immaterial, typically fluctuating within a narrow band around zero.
