Net Income

Net income represents the final profit figure after every expense has been accounted for, cost of goods sold, operating expenses, interest payments, taxes, depreciation, and any one-time charges. It is the "bottom line" of the income statement and the number used to calculate earnings per share. Net income matters because it shows what the company actually keeps after running its entire operation. However, net income can be volatile and sometimes misleading. One-time charges like restructuring costs, asset write-downs, or legal settlements can dramatically swing net income without reflecting the ongoing health of the business. That is why many analysts also look at adjusted net income or operating income for a cleaner picture. For S&P 500 companies, net income margins vary dramatically by sector, technology companies might earn 20-30% net margins while retailers operate on 2-5%. Comparing net income across sectors is less useful than comparing within sectors. Rising net income alongside rising revenue is the gold standard signal. If net income is growing while revenue is flat, the company is cutting costs, which is not sustainable long-term. Operators should watch net income trends to understand whether their customers or partners are becoming more or less profitable.
