The group is within the scope of the OECD Pillar Two model rules. Pillar
Two legislation was adopted in Luxembourg, the jurisdiction in which the Company is incorporated, and came into effect as from January
1, 2024. The group applies the exception regarding the recognition and disclosure of deferred tax assets and liabilities related to Pillar
Two income taxes, as provided for in the amendments to IAS 12 issued in May 2023.

For the year 2024, Tenaris recognized an estimated current tax expense
related to Pillar Two, amounting to $81.4 million.

The tax charge differs from the theoretical amount that would arise by
applying the nominal tax rate valid in each jurisdiction to the group's pre-tax income in that jurisdiction as follows:
