 otherwise stated |

In late March 2024, the Company became aware of a resolution of Brazil’s
General Controllers Office, which opened administrative responsibility proceedings against Confab and other non-Tenaris affiliates and
formed an investigative commission charged with investigating purported irregularities referred to in certain 2019 administrative
proceedings. Confab has recently received notice of these proceedings and, based on a preliminary analysis, believes that the General
Controllers Office proceedings do not address either the defence arguments or the evidence available to the plaintiffs in Brazil and presented
in other jurisdictions and will vigorously contest them. At this stage, however, the Company cannot predict the outcome of these administrative
proceedings.

| § | Administrative proceeding concerning Brazilian tax credits |

Confab is a party to an administrative proceeding concerning the recognition
and transfer of tax credits for an amount allegedly exceeding the amount that Confab would have been entitled to recognize and / or transfer.
The proceeding resulted in the imposition of a fine against Confab representing approximately 75% of the allegedly undue credits, which
was appealed by Confab. On January 21, 2019, Confab was notified of an administrative decision denying Confab’s appeal, thereby
upholding the tax determination and the fine against Confab. On January 28, 2019, Confab challenged such administrative decision. Special
appeals were filed by Confab in July 2023 and by the Brazilian General Tax Attorney in September 2023. The parties are currently awaiting
a resolution. In case of an unfavorable resolution, Confab may appeal before the courts. The estimated amount of this claim is BRL62.1
million (approximately $10.0 million). At this stage, the Company cannot predict the outcome of this
claim.

| § | U.S. patent infringement litigation |

Tenaris Coiled Tubes, LLC (“TCT”), a U.S. subsidiary of the
Company, was sued in 2017 by its competitor Global Tubing, alleging defamatory conduct by TCT and seeking a declaration that certain Global
Tubing products do not infringe patents held by TCT. TCT counterclaimed that certain Global Tubing products did infringe patents held
by TCT, and Global Tubing has since sought to invalidate such patents. On December 13, 2019, Global Tubing filed an amended complaint
(including the Company as defendant), alleging, among other things, that TCT and the Company had misled the patent office. On March 20,
