‘exceptional items’ presentation as described further in Note 1 to the Unaudited pro forma Combined Financial Information. Furthermore, certain adjustments were made to amounts in Borsa Italiana Group’s Consolidated Statement of Profit or Loss to align with Euronext N.V.‘s accounting policies as described in Note 2 to the Unaudited pro forma Combined Financial Information. During 2021, no further acquisitions were undertaken by Euronext N.V. resulting in a significant gross change that could be subject to inclusion in the Unaudited pro forma Combined Financial Information presented hereby.

The pro forma adjustments included in the Unaudited pro forma Combined Financial Information are limited to those that are (i) directly attributable to the Transaction and (ii) factually supportable. The Unaudited pro forma Combined Financial Information does not reflect items such as Euronext N.V.’s expected synergies or operating efficiencies that result from the Transaction. Euronext N.V. has performed a review of Borsa Italiana Group IFRS disclosures and accounting policies to determine whether any adjustments were necessary to ensure comparability in the Unaudited pro forma Combined Financial Information. Certain reclassifications were made to amounts in Borsa Italiana Group’s Consolidated Statement of Profit or Loss to align with Euronext N.V.’s
