Comparison of adjusted information to

U.S. GAAP information

This presentation includes Company financials on an as-reported basis. The Company also refers to and presents certain additional non-GAAP financial measures, within the meaning of Regulation G under the Securities Exchange Act of 1934. These measures are: adjusted operating profit and margin; trailing twelve-month adjusted operating profit and margin; adjusted operating profit from OSTTRA JV (net of tax); adjusted expenses; adjusted corporate unallocated expense; organic constant currency revenue; adjusted interest expense, net; adjusted effective tax rate; adjusted net income (less NCI); adjusted diluted EPS; free cash flow and adjusted free cash flow, excluding certain items; EBITDA and adjusted EBITDA; adjusted gross debt; and adjusted net debt.

The Company is not able to provide reconciliations of certain forward-looking non-GAAP financial measures to comparable GAAP measures because certain items required for such reconciliations are outside of the Company's control and/or cannot be reasonably predicted without unreasonable effort.

The Company's non-GAAP measures include adjustments that reflect how management views our businesses. The Company believes these non-GAAP financial measures provide useful supplemental information that, in the case of non-GAAP financial measures other than free cash flow and adjusted free cash flow excluding certain items, enables investors to better compare the Company's performance across periods, and management also uses these measures internally to assess the operating performance of its business, to assess performance for employee compensation purposes and to decide how to allocate resources. The Company believes that the presentation of free cash flow and adjusted free cash flow excluding certain items allows investors to evaluate the cash generated from our underlying operations in a manner similar to the method used by management and that such measures are useful in evaluating the cash available to us to prepay debt, make strategic acquisitions and investments, and repurchase stock. However, investors should not consider any of these non-GAAP measures in isolation from, or as a substitute for, the financial information that the Company reports.

The Company completed the spin-off of its Mobility division, creating an independent public company, Mobility Global (NYSE: MBGL), on July 1, 2026. Effective with the Company's third-quarter 2026 financial statements, Mobility has been reclassified as discontinued operations for all completed periods presented. All financial information presented in this presentation reflects the Company's results on a continuing operations basis, unless otherwise stated, and prior periods have been recast accordingly to conform to this presentation. Division results presented in this presentation also reflect a recast of the Company's division financial information for all periods presented, including inter-segment adjustments and changes to expense allocation methodologies as outlined in the Company's press release dated July 6, 2026.

The Company's earnings releases, including its earnings release dated October 27, 2026, contain financial measures calculated in accordance with GAAP that correspond to the non-GAAP measures included in this presentation, and the earnings releases and this presentation contain reconciliations of such GAAP and non-GAAP measures. The Company's earnings releases and this presentation are available on the Company's website at https://investor.spglobal.com/quarterly-earnings.
