One business owner has run a company for years where a single client accounts for half of all revenue. During a loan consultation, a bank officer asked her to explain why that client posed a risk — and she found herself at a loss for words. All she could say was that it made her uneasy. That's exactly the moment when knowing how to define business risk matters. Today, we'll use Nvidia's recent 10-K filing — from the world's largest semiconductor company — as a case study in how a major corporation translates its own risks into numbers. This isn't about buying or selling Nvidia stock. It's an exercise in borrowing the way large companies describe risk and applying it to your own business.

Three Questions That Turn Risk Into Numbers

Even a risk that feels vague turns into something manageable once you answer three questions with numbers. First, if that variable shifts, how much does revenue or cost actually move? Second, can you predict when that impact will show up, or is even the timing unknown? Third, why is that variable connected to your business structure in the first place? Making a habit of answering all three with hard numbers is the essence of defining business risk.

How Nvidia Puts Its Risks Into Words

Nvidia's capital expenditures (CapEx) jumped 79%, from $3.4 billion in fiscal 2025 to $6.1 billion in fiscal 2026. That number alone isn't the risk. The real risk starts with how much this spending squeezes free cash flow — net income plus depreciation and amortization, minus CapEx — and in turn how much room is left for dividends and share buybacks. Here's that chain laid out as a diagram.

In short, the real risk isn't the size of the investment — it's the path connecting that investment to cash and dividend capacity.

On taxes, the timing risk is especially clear. Nvidia carries $4.0 billion in unrecognized tax benefits as a liability, of which $370 million is interest and penalties alone. The IRS is currently examining fiscal years 2023 and 2024, and the company states it cannot predict when that review will conclude. When you know the size of a risk but not its timing, that distinction needs its own separate line.

Currency exposure needs to be scoped precisely, too. A 10% strengthening of the dollar would swing the mark-to-market value of Nvidia's forward contracts alone by $180 million, versus $136 million a year earlier. The effect on actual sales is a separate matter, showing up instead through the channel of overseas customers delaying purchases because their local currency has weakened. Keeping hedging gains and losses separate from operating results is part of putting risk into precise language.

Translating This Into Your Own Numbers

You can apply this exact framework to your own business. If one client accounts for half your revenue, calculate what percentage your revenue would drop and how much fixed cost would remain if that client left. If you're exposed to external variables like raw material costs or rent, calculate exactly how much your costs would change if that variable moved 10%, and write it down alongside your contracts or business plan. And for risks with an unknown timeline — taxes, licensing approvals — simply labeling them "timing unknown" alongside their size changes how convincingly you can explain them.

One Thing to Try Today

Write down what percentage of your revenue comes from your single largest client. Then write two numbers: the revenue that would remain, and the fixed costs that would remain, if that client disappeared. With just those two lines, the next time a bank or investor asks, you can answer with hard numbers instead of saying you're just worried.
