The bridge from revenue to net income
Do not start and end with the bottom line. Revenue less cost of sales gives gross profit; operating expenses and related items lead to operating results. Financing and taxes can change net income. Rising sales with falling operating profit calls for a review of pricing, product mix, input costs and expenses. Presentation varies by sector and accounting standard, so use the explanatory notes.
Example: growing sales, shrinking margin
Assume revenue rises from TRY100 million to TRY120 million while gross profit increases from TRY30 million to TRY32 million. Sales grow 20%, gross profit about 6.67%, and gross margin falls from 30% to 26.67%. More sales now leave less gross profit per unit of revenue. That is not proof of poor management: discounts, a new product, temporary costs or currency effects could contribute. Investigate segment and cost disclosures.
Separate earnings quality
Asset-sale gains, deferred taxes or FX gains can lift net income without being recurring. Diverging operating and net results deserve explanation. If using adjusted earnings, record which costs were removed. Repeatedly excluding a recurring expense as a one-off weakens comparability. Accounting profit should not be equated with cash collected.
Quarter, year and price level
For seasonal businesses, compare the corresponding prior-year quarter as well as the preceding quarter. Derive a standalone quarter by subtracting the previous year-to-date period on a consistent basis. Check restatements when inflation accounting or reporting currency changes. Nominal revenue growth does not automatically mean greater volume; higher prices can also increase revenue.
Checks for the next stage
Record reporting scope, sales growth, gross and operating margins, financing costs, tax rate, unusual items, share count and EPS. Then check cash conversion. Do not treat banking and industrial margins as identical measures. The purpose is to understand the business and conditions behind profit, rather than find one universally good percentage.
