Visa and Mastercard run near-identical businesses, grow at near-identical rates, and trade at near-identical multiples. Investily scores Visa 66 and Mastercard 58. When two companies this similar score eight points apart, the difference is almost always somewhere people don't look — and here it is entirely on the balance sheet.
How alike they actually are
- Revenue growth, trailing year — Mastercard 18.9%, Visa 17.0%
- Trailing P/E — effectively the same for both
- Net margin — Visa 52.2%, Mastercard 44.9%
- Forward multiple on next year's consensus — within a point of each other
Two companies, one duopoly, the same growth rate, the same price. On the evidence most comparisons use, there is nothing to choose between them.
Mastercard appears to win on returns
Return on capital employed is where they separate, and at first glance it separates them decisively in Mastercard's favour: 52.1% against Visa's 36.9%. Both are excellent. Mastercard's is exceptional, and it has been consistently so — 53.7% over three years.
Taken at face value, Mastercard earns half again as much on every dollar employed in the business. That should make it the higher-scoring stock, not the lower one.
Why the score disagrees
Returns are a ratio, and a ratio improves either when the numerator rises or the denominator falls. At Mastercard, the denominator is falling — fast. Book value shrank 26.5% over the trailing year, and has gone backwards over five. Visa's fell 7.8% over the same year.
Both companies buy back stock aggressively, which mechanically shrinks equity. Mastercard does it harder, and funds more of it with borrowing. The result shows up in two places:
- Debt to equity — Mastercard 2.4, Visa 0.7
- Price to book — Mastercard 92.6x, Visa 20.8x
A price-to-book of 92 is not a valuation signal in the usual sense. It is what happens when a company has bought back so much stock that there is almost no book equity left to divide by. Mastercard's superior return on capital is partly real and partly the arithmetic of a shrinking capital base.
The lesson worth more than the verdict
We generally prefer ROCE to return on equity precisely because it counts debt and equity together, so borrowing cannot flatter it. Mastercard is a useful reminder that no single ratio is manipulation-proof. Sustained buybacks funded by debt shrink capital employed, and shrinking the denominator raises the return whether or not the business improved.
The defence against this is not to abandon the metric. It is to read it alongside the balance sheet — check whether book value is growing or shrinking, and check debt to equity. When returns are rising while equity is disappearing, you are looking at financial engineering as much as operating performance.
The bottom line
Visa scores higher not because it is the better operator on any single line, but because it produces very similar economics with a materially more conservative balance sheet. You are paying the same multiple for the same growth in the same duopoly — and one of the two has three times the leverage.
Neither is a bad business; a duopoly on global payments rarely is. But if the two are priced identically, the balance sheet is the only thing left to choose on. For the framework behind this, what ROCE measures and where it breaks covers the same ground in general terms.
