S&P Global's stock experienced a significant pre-market plunge of 5.68% on Tuesday, following the release of its quarterly financial results.

The sharp decline appears to be driven by the company's fourth-quarter adjusted earnings per share of $4.30, which fell short of the FactSet consensus estimate of $4.33. This earnings miss has likely disappointed investors and triggered the sell-off in pre-market trading.

While the company reported revenue that slightly exceeded expectations, the key profitability metric failing to meet analyst forecasts has overshadowed other positive aspects of the earnings report, leading to negative sentiment in the pre-market session.
