International Business Machines Corp. (NYSE:IBM)

The common-size income statement reveals a significant shift in the company’s revenue composition and profitability over the five-year period. Revenue contributions from Services decreased consistently, while those from Sales increased, indicating a strategic move towards a greater reliance on product sales. Cost of revenue as a percentage of revenue generally decreased, contributing to improved gross margins. Operating income demonstrated a positive trend, though with some volatility, and net income showed substantial improvement over the period.

Revenue Composition

The proportion of revenue derived from Services declined steadily from 50.96% in 2021 to 45.48% in 2025. Conversely, Sales increased from 47.68% to 53.43% over the same period. Financing remained a relatively small and stable component of revenue, fluctuating between 1.08% and 1.36%. This suggests a strategic shift in focus from service-based revenue to product sales.

Profitability Analysis

Gross profit as a percentage of revenue improved consistently, rising from 54.90% in 2021 to 58.19% in 2025. This improvement is partially attributable to the decreasing cost of revenue, which fell from 45.10% to 41.81% over the same timeframe. Operating income showed a generally positive trend, increasing from 11.97% to 17.50%, although there was a slight dip in 2024. Net income exhibited the most dramatic improvement, increasing from 10.05% in 2021 to 15.72% in 2025.

Operating Expenses

Selling, general and administrative expenses decreased as a percentage of revenue, moving from 32.69% in 2021 to 29.80% in 2025, indicating improved efficiency in these areas. Research and development expenses remained relatively stable, fluctuating between 10.85% and 12.31%. Intellectual property and custom development income showed a modest increase over the period.

Non-Operating Items

Gains (losses) on foreign currency transactions and derivative instruments were volatile, with fluctuations throughout the period. Interest income increased significantly from 0.09% to 1.19% before decreasing slightly to 0.96% in 2025. Interest expense remained relatively consistent, though it did increase slightly over the five years. Other income and (expense) experienced significant volatility, particularly in 2022, before stabilizing in later years. Retirement-related income (costs) showed considerable fluctuation, with a large expense in 2022 followed by income in 2023 and expenses in 2024 and 2025.

Tax Impact

The (provision for) benefit from income taxes varied considerably, ranging from a benefit of 1.90% in 2023 to an expense of 1.03% in 2022. This variability likely reflects changes in taxable income and applicable tax rates.

Discontinued Operations & Net Income

Income (loss) from discontinued operations was minimal, with a slight positive contribution in most years. Net income attributable to IBM followed the overall trend of increasing profitability, rising from 2.71% to 15.69%.

Overall, the company demonstrated a positive trajectory in profitability, driven by a shift in revenue composition, improved gross margins, and effective management of operating expenses. However, the volatility of certain non-operating items warrants further investigation.
