The Zacks Consensus Estimate for revenues stands at $1.96 billion, indicating growth of 9.8% from the year-ago period’s reported figure.Segment wise, Ratings revenues are likely to have been driven by strength across both non-transaction and transaction revenues.

Transaction revenues might have been aided by rise in bank loan ratings revenues. Market Intelligence revenues are expected to have gained from growth in Data Management Solutions, Credit Risk Services, and Desktop. Platts revenues might have benefited from growth in the core subscription business. Indices revenues are likely to have been aided by gains in asset-linked fees.Revenue growth, productivity programs, lower effective tax rate and decline in the average shares outstanding are likely to have boosted S&P Global’s first-quarter 2021 earnings, the Zacks Consensus Estimate for which is pegged at $3.13 per share, indicating growth of 14.7% from the year-ago period reported figure.What Our Model Says Our proven model predicts an earnings beat for S&P Global this time around.
