conduct during the patent prosecution process. TCT appealed this judgment, and Global Tubing appealed a previous ruling of the judge.
Global Tubing also filed a brief seeking to recover attorneys’ fees, without specifying the amount of those fees. The proceedings
are ongoing. Although it is not possible to predict the final outcome of this matter, the Company believes that any potential losses arising
from this case will not be material.

§U.S. Antidumping Duty Investigations

On October 27, 2021, the U.S. Department of Commerce (“DOC”)
initiated antidumping duty investigations of oil country tubular goods (“OCTG”) from Argentina, Mexico, and Russia. After
the DOC issued affirmative preliminary and final antidumping determinations with respect to imports from Argentina, Mexico and Russia
on October 27, 2022, the International Trade Commission (“ITC”) determined that the imports under investigation caused injury
to the U.S. OCTG industry. Tenaris and other parties have appealed the agency determinations from the investigation to the Court of International
Trade, and, with respect to certain claims, to the Court of Appeals for the Federal Circuit. In addition, in response to a request from
the Government of Argentina, the World Trade Organization (“WTO”) established a panel of experts to consider whether the DOC’s
antidumping order applicable to Argentina is consistent with the international obligations of the United States.

As a result of the investigations, and pending the outcome of the referenced
appeals, Tenaris is required to pay antidumping duty deposits (at a rate of 78.30% for imports from Argentina and 44.93% for imports from
Mexico) until such time the imports are reviewed by the DOC to determine whether final duties are necessary for the specific period under
review. Tenaris has been paying such deposits since May 11, 2022, reflecting the amount of such deposits in its costs. The deposit rates
may be reset periodically based on the results of the administrative review process. In the first administrative review covering the period
from May 11, 2022, to October 31, 2023, the DOC issued preliminary determinations with respect to imports from both Argentina and Mexico.
