S&P Global delivered first-quarter adjusted EPS of $4.97, beating the consensus forecast of $4.82, on revenue of $4.17 billion versus expectations of roughly $4.08 billion. Revenue rose 10% year-over-year; adjusted diluted EPS climbed 14%.

Market Intelligence grew 8% to $1.296 billion, while Energy and Mobility delivered increases of 7% and 8%, respectively. Every division expanded margins. The adjusted operating profit margin reached 51.8%, up 100 basis points from the prior-year period, with management noting that margins in each division exceeded the outlook set just two months earlier at the annual guidance call.

This was not a one-trick quarter.

Management acknowledged that some of the strength reflected front-end loading of hyperscaler debt relative to initial expectations—large technology companies pulling forward capital-markets activity to lock in financing ahead of potential geopolitical disruption.

This is the honest complication in the bullish case. Management does not expect acceleration in Ratings revenue growth in Q2, and...
