NVIDIA's margin bridge — where each point goes

mentor: One income statement carries three margins, and the walk between them is the story: gross marginDefinitionGross marginThe share of each revenue dollar left after the direct cost of producing what was sold. It is the first read on pricing power and production efficiency, and the starting point of every margin analysis.Gross margin = Gross profit ÷ Revenue = (Revenue − Cost of revenue) ÷ RevenueDrivers: Price · Cost · Volume · MixFull definition → is what survives the direct cost of the product, operating marginDefinitionOperating marginOperating income as a share of revenue — what remains after both the direct cost of sales and the operating expenses (R&D, sales & marketing, G&A) that run the business. It measures how much of the gross margin survives the cost of operating the company.Operating margin = Operating income ÷ RevenueDrivers: Gross margin · Opex leverage · One-time itemsFull definition → is what survives running the company, and net marginDefinitionNet marginNet income as a share of revenue — the bottom line after every cost: operations, interest, taxes, and one-offs.

Below is NVIDIA's full income-statement walk from its latest annual reportDefinitionForm 10-KThe audited annual report a US public company files with the SEC — the most complete single document about a business: audited financial statements, management's discussion, risk factors, and the auditor's own opinion. It is the primary source nearly every figure on Echelon grounds to.One 10-K = audited statements + MD&A + risk factors + auditor's reportDrivers: Assurance · Cadence · Restated comparativesFull definition → (Form 10-K), via SEC EDGAR. Compute all three margins from the same filed year and read the bridge between them.

Each margin divides its own filed line by revenue: gross profit ÷ revenue, operating income ÷ revenue, net income ÷ revenue — all from one fiscal yearDefinitionFiscal yearThe company's own 12-month reporting window — which need not match the calendar. Two filers can both report 'fiscal 2026' over windows months apart, so a shared FY label is not a shared period: honest comparison aligns filers by period-end date, never by the label.Fiscal year = the filer's chosen 12-month window (some retail calendars run 52/53 weeks)Drivers: Year-end choice · Label conventionFull definition →.
