Revenue exhibits a significant long-term upward trajectory, growing from 1.54 billion dollars in September 2020 to 4.14 billion dollars by September 2026. This growth is primarily driven by the product segment, which experienced a peak in December 2022 followed by a period of stabilization through 2023 before resuming an aggressive growth phase from 2024 onward. The service segment demonstrates a consistent, linear expansion, increasing from 393 million dollars to 850 million dollars over the analyzed period, providing a stable revenue base that complements the more volatile product sales.

Gross Profitability and Margin Trends
Gross margin expanded from 918 million dollars to 2.56 billion dollars. The cost of revenues has scaled proportionally with revenue, maintaining a relatively stable gross margin percentage throughout the period. A notable resilience in margin is observed even during the 2023 revenue plateau, indicating effective cost management and pricing power.
Operational Expense Management
Research and development (R&D) and selling, general and administrative (SG&A) expenses both show a gradual increase. R&D spending rose from 219 million dollars to 395 million dollars, while SG&A grew from 172 million dollars to 301 million dollars. The growth in these operational costs is significantly slower than the growth in total revenues, suggesting positive operating leverage.
Operating Income and Impairments
Income from operations grew from 526 million dollars in September 2020 to 1.86 billion dollars in September 2026. This growth was interrupted by intermittent impairment charges related to goodwill and intangible assets, specifically noted in December 2023, March 2024, and March 2025, which caused temporary dips in operating performance.
Net Income and Fiscal Impact
Net income attributable to the company increased from 420 million dollars to 1.55 billion dollars. The bottom line exhibited volatility primarily due to fluctuations in tax provisions and benefits, most notably a substantial tax benefit in September 2021. Interest expenses shifted from approximately 39 million dollars per quarter in 2020 to a higher range of 68 to 83 million dollars in later years, though this remained manageable relative to operating income growth.

The overall financial trend indicates a transition from a period of rapid post-2020 growth into a phase of consolidation in 2023, followed by a secondary acceleration in scale by 2025 and 2026. The expansion of the service revenue stream and the disciplined scaling of operating expenses have contributed to a strengthened net income profile.
