Third Share Buyback Program

The Company’s ordinary shareholders meeting held on May 6, 2025,
renewed the authorization to purchase, acquire or receive, from time to time, Company shares, including shares represented by ADRs, on
such terms and conditions as may be approved by the board of directors up to a maximum of 10% of the Company’s shares.

On May 27, 2025, the Company’s board of directors approved a third
share buyback program of up to $1.2 billion (excluding incidental transaction fees), to be executed within a year, with the intention
to cancel the ordinary shares acquired through the program. The third share buyback program is carried out under the authority granted
by the annual general meeting of shareholders held on May 6, 2025, up to a maximum of 10% of the Company’s shares.

The third share buyback program is divided into tranches. The first tranche
of the program will cover up to $600 million (excluding incidental transaction fees) and will run from June 9, 2025, to (and including)
December 8, 2025. Ordinary shares purchased under the third share buyback program will be cancelled in due course. For purposes of carrying
out each tranche of the third share buyback program, the Company entered into a non-discretionary buyback agreement with a primary financial
institution, which makes trading decisions concerning the timing of the purchases of the Company’s shares independently of and uninfluenced
by Tenaris and acts in compliance with applicable rules and regulations, including the Market Abuse Regulation 596/2014 and the Commission
Delegated Regulation (EU) 2016/1052.

During the six-month period ended June 30, 2025, the Company purchased
12,277,261 shares, for approximately $235 million under the second share buyback program and purchased 13,094,268
shares, for approximately $237 million under the third share buyback program.

During the six-month period ended June 30, 2024, the Company purchased
48,873,790 shares, for approximately $831 million (out of which approximately $803 million were paid).

As of June 30, 2025, the Company held in treasury the 13,094,268
ordinary shares repurchased under the third share buyback program. The Company intends
