Why the Market Sold the Best Ratings Quarter in Years

S&P Global did something on July 28 that a quality compounder is not supposed to do: it beat, it raised, and it fell. Adjusted diluted EPS of $4.83 rose 23% year over year, revenue climbed 10% to $4.15 billion, and management lifted both its full-year buyback target and the guidance on its two best divisions — and the stock closed the session lower and has drifted to $411.93, roughly a quarter below its 52-week high of $547.82 and only about 14% off the $361.03 low. That is the tape of a name where the marginal buyer has decided the quarter was a top rather than a turn. The wager this piece makes is that they are wrong on the one thing that matters: the durability of the engine that drove it.

To see why, you have to know what S&P Global now is. After spinning off its Mobility (auto-data) business as an independent company on July 1, 2026 — a one-for-one share distribution that removes roughly $1.75 billion of annual revenue and reclassifies Mobility's history as discontinued operations from Q3 — the company is a cleaner, four-division benchmark-and-data franchise . Ratings assigns credit ratings that issuers must carry to sell debt into the public markets; S&P Dow Jones Indices licenses the S&P 500 and Dow Jones benchmarks and collects a fee on the assets that track them; Market Intelligence sells subscription data and analytics through the Capital IQ platform; and Energy (the former Platts/Commodity Insights franchise) sells price assessments and analytics into commodity markets. On a trailing-twelve-month basis after the spin, Ratings is about 35% of revenue, Market Intelligence 33%, Energy 18%, and Indices 14% — but the two benchmark franchises, Ratings and Indices, throw off roughly 63% of adjusted operating profit between them, and benchmark products broadly (which also fold in Platts and ratings distribution) reach ~80% . That concentration of profit in a pair of toll-booth businesses is the whole story.

The Quarter the Market Refused to Believe

Start with what is demonstrated, because the bull case here rests on realized results, not projections. Ratings posted a record quarter, with revenue up...
