APPENDIX A

Reconciliation of Non-GAAP Financial Information

The following tables reconcile non-GAAP financial information included in this Proxy Statement to the most directly comparable measures presented in accordance with generally accepted accounting principles (“GAAP”) in the U.S. and reported in our consolidated financial statements filed with the Securities and Exchange Commission. The non-GAAP financial information included in this Proxy Statement has been provided in order to show investors how our Compensation Committee views the Company’s performance as it relates to the compensation program for our named executive officers. This non-GAAP financial information may be different from similar measures used by other companies. For 2022, adjusted financials are presented on a pro forma basis as if the merger with IHS Markit had closed on January 1, 2021.

​

Note: Diluted weighted average shares outstanding of 305.1 million was used to calculate adjusted diluted earnings per share. For 2022, base year non-GAAP pro forma Adjusted EPS of $11.19 was calculated as article 11 S&P Global diluted EPS adjusted for non-GAAP pro forma adjustments. For pro forma to non-GAAP pro forma adjusted reconciliations refer to Exhibit 99.2 of the current report on Form 8-K furnished on August 2, 2022.
