Equifax grew operating profit 3.6× as fast as revenue, and that lever does not only push upward

A good quarter for sales, a stronger one for profit

Equifax is one of the large US credit bureaus: it collects data on how people and companies borrow and repay, and sells credit reports, scores and analytics to lenders, employers and others. In the third quarter of 2026, July to September, it booked revenue of USD 1.7bn, up 9.6% on the same quarter of 2025, when it reported USD 1.5bn. All figures are consolidated for the whole group, in US dollars, under US GAAP, the American accounting rules.

That is solid growth, but not dramatic. Operating profit is where the quarter becomes unusual. It rose from USD 264m to USD 355m, an increase of 34.4%. Profit grew 3.6× as fast as revenue. The operating margin, the share of each dollar of revenue left after paying for the running of the business, widened from 17.1% to 21.0%, a gain of 3.9 pp.

The effect carried all the way down. Net profit, what remains after interest and tax, rose 32.1% to USD 212m, and the net margin moved from 10.4% to 12.5%. Investors noticed: Kurzy.cz listed Equifax among the biggest gainers in the S&P index in October 2026.

The tension is simple. Revenue added USD 148m, while operating profit added USD 91.0m. A business does not normally keep most of each extra dollar it sells. This one, in this quarter, kept a remarkable share of it.

Why a credit bureau's profit outruns its sales

The explanation lies in how a data business is built. The expensive part is the database itself: collecting records from lenders, cleaning them, storing them securely, keeping the technology platform running, and paying the analysts, engineers and compliance staff who do all of that. Those costs are largely there whether the company sells a few more reports in a quarter or a few fewer. Producing an additional credit report costs almost nothing. Once revenue covers the fixed base, most of each extra dollar falls to operating profit.

One cost line shows the pattern clearly. Depreciation and amortisation, the accounting charge that spreads the cost of software, data and equipment over the years they are used, rose only from USD 183m to USD 194m. Revenue grew much faster than that charge. A company that has already built its platform does not need to build it again to serve more customers.

This also explains a detail in the margins. EBITDA, operating profit before depreciation and amortisation, rose 22.8% to USD 550m. That is strong, but well below the 34.4% growth in operating profit. The gap exists because the depreciation charge, which sits between the two, grew slowly. The heavy investment of earlier years is now being spread over a bigger revenue base, and that alone flatters operating profit.

What the quarterly accounts do not settle is where the extra revenue came from. It could be more volume, for example more loan and mortgage applications triggering credit checks, or higher prices, or a richer product mix. The consolidated statement does not split revenue growth between volume and price; revenue by segment and by product would show it. The distinction matters. Price increases and product mix tend to last. Volume that follows the lending cycle comes and goes with interest rates.

The balance sheet does not tell the same cheerful story, though it is a side note here. Equity fell USD 466m to USD 4.5bn, and the equity ratio, equity as a share of total assets, slipped from 41.7% to 37.5%. Cash stood at USD 193m, close to the USD 189m of a year earlier. The extra profit did not pile up as cash or equity. The accounts do not show where it went, and I would watch that line in the coming quarters.

The same lever works in a weak quarter

Economists call this operating gearing: the way fixed costs amplify changes in sales. It is not a reward for good management. It is a property of the cost structure, and it works in both directions. When revenue rises, fixed costs stay put and profit jumps. When revenue falls, fixed costs stay put as well, and profit drops faster than sales.

That is why I would not read the 34.4% jump as a step change in the business. It is one quarter compared with the same quarter a year earlier. If the extra revenue was driven by a busy lending market, a quieter one would run the same mechanism in reverse. A ratio of 3.6× applied to a fall in revenue is not a pleasant calculation.

None of this means the result is weak. A margin of 21.0% is a real improvement on 17.1%. It means the result is sensitive: the margin depends on the revenue line holding up, more than on anything the company does with its costs in a given quarter.

What to check in your own company

You do not need a credit bureau to have the same lever. Any business with a large share of costs that do not move with sales has it: software firms, manufacturers, hotels, agencies with a salaried team, logistics companies with their own fleet.

Start with your last comparable periods, this year against last. Divide the percentage change in operating profit by the percentage change in revenue. A result well above one means your profit swings harder than your sales.

Then open your cost report and sort every line into a pair of columns. In the first, costs that would fall within a quarter if orders dropped: materials, commissions, subcontractors paid per job, transaction fees. In the second, costs that would not: salaries, rent, leases, software licences, depreciation. Go by the contracts, not by the account names. A multi-year lease is fixed until it ends, whatever the ledger calls it.

With those columns you can work out your break-even point: divide fixed costs by the share of each revenue dollar left after variable costs. Compare that figure with your current revenue. The distance between them is how far sales can fall before operating profit reaches zero. It is better to learn that distance in a good year than in a bad one.

A strong quarter, not a different company

Equifax turned modest revenue growth into a sharp rise in profit because its costs were already paid for. That is the plain arithmetic of a data business, and in the third quarter of 2026 it worked in the company's favour. The lever that lifted the margin has not gone anywhere. It will amplify the next quarter's revenue too, in whichever direction that revenue moves.
