Revenue composition
Product revenue as a percentage of total revenue showed a rising trend from 78.56% in March 2020, reaching a peak around 86.73% in March 2023, then experiencing a slight decline but remaining above 83% through March 2025. Conversely, service revenue exhibited a declining trend, decreasing from 21.44% in March 2020 to a low of approximately 13.27% in March 2023, with a moderate recovery to around 15.58% by March 2025.
Cost of revenue and gross profit
Cost of revenue increased steadily from 35.33% of total revenue in March 2020 to peak levels near 40.47% in December 2022, before slightly moderating to approximately 36.35% in March 2025. This increase implies rising expenses related to generating revenue. Consequently, gross profit margin declined from 64.67% in March 2020 to a low near 59.53% in March 2023, followed by a recovery phase reaching about 63.65% in March 2025.
Profitability and income measures
Income from operations demonstrated an upward trajectory overall, moving from 28.61% in March 2020 to a high of approximately 43.36% in December 2024, slightly reducing afterward to about 42.84% in March 2025. Income before income taxes followed a similar positive trend, increasing from 30.94% in March 2020 to nearly 48.75% in December 2024, with a mild decline to 47.64% in March 2025. Net income as a percentage of revenue grew steadily from 26.47% in March 2020 to a peak of 41.49% around December 2024, maintaining roughly 40.59% by March 2025.
Operating expenses
Operating expenses as a percentage of revenue decreased significantly during the period under review. Research and development expenses fell from about 21.63% in March 2020 to near 13.29% in March 2025, sales and marketing expenses similarly declined from roughly 10.91% to 5.82%, and general and administrative costs reduced from 3.51% to 1.71%. This decline in operating expenses likely contributed to improved operating margins.
Other income and provision for income taxes
Other income (expense), net, showed some fluctuations but generally increased as a percentage of revenue, from around 2.32% in March 2020 to levels near 4.80% in March 2025, indicating higher non-operating gains or income. The provision for income taxes fluctuated during the period without a clear trend, varying approximately between -7.45% and -1.38%, reflecting variability in tax expenses relative to revenue.
Summary of trends
Overall, the data indicates a shift towards a higher proportion of product revenue accompanied by reductions in service revenue percentage. Despite rising cost of revenue, improvements in operating expenses contributed to enhanced profitability metrics including income from operations and net income margins. Variability in other income and tax provisions underscores some fluctuations in non-operating factors and tax efficiency, but the general financial health as reflected by profitability ratios appears to have strengthened over the analyzed periods.
