The common-size income statement reveals significant fluctuations in Micron Technology’s profitability and cost structure over the analyzed period, spanning from November 2019 to May 2025. Revenue is consistently represented as 100% by definition. A notable trend emerges in the cost of goods sold, initially decreasing before experiencing a substantial increase, peaking in March 2023, and then declining significantly.
Gross Margin
Gross margin demonstrates a generally increasing trend from 26.56% in November 2019 to a peak of 47.28% in September 2021. However, this is followed by a dramatic decline, reaching a low of -32.66% in March 2022, before recovering to 38.44% by September 2022. Further increases are observed, peaking at 74.41% in February 2026, indicating substantial improvements in profitability in the latter part of the period.
Operating Expenses
Research and development expenses remained relatively stable as a percentage of revenue, fluctuating between approximately 8.5% and 14.3% throughout the period. Selling, general, and administrative expenses also exhibited relative stability, generally ranging between 2.8% and 6.1%. Restructure and asset impairments were minimal until March 2023, where they reached 2.33% of revenue, before becoming negligible again. Other operating income (expense), net, showed considerable volatility, swinging from positive to negative values.
Operating Income
Operating income mirrored the trends observed in gross margin. It increased from 10.07% in November 2019 to a high of 35.71% in September 2021, then plummeted to -62.36% in March 2022. A recovery began, reaching 67.73% in February 2026, demonstrating a strong turnaround in operational performance.
Non-Operating Items & Net Income
Interest income consistently contributed a small positive percentage to revenue, while interest expense represented a slightly larger negative percentage. The impact of other non-operating items was variable. Net income followed a similar pattern to operating income, with a significant loss in March 2022 (-62.60%) followed by a substantial recovery, culminating in 57.77% in February 2026. Net income attributable to noncontrolling interests was consistently a small negative percentage of revenue.
Overall, the period was characterized by significant volatility, particularly in the first half. The company experienced a substantial downturn in profitability around March 2022, but demonstrated a strong recovery in subsequent periods, culminating in significantly improved margins and net income by the end of the analyzed timeframe. The substantial increase in cost of goods sold in early 2022 appears to be a key driver of the initial decline, while subsequent cost control and revenue growth contributed to the later recovery.
