the material in the warehouse and the amount of the material stored. In the majority of cases, to quantify the amount to be invoiced in
any given month, the monthly average fee of storage per ton is multiplied by the monthly average stock stored (in tons).

Freights: the revenue is recognized on a pro rata basis considering the units delivered and time elapsed.

Field services: the revenue is recognized considering output methods, in particular surveys of service completion provided by the customer.

The Company also provides other services, such as hydraulic fracturing,
coiled tubing and coating services. Regarding these services, the inputs and outputs methods to recognize the revenue are the following:

Coating services:the Company provides coating services on third-party
tubes which are performed under specific contracts and recognized by reference to the stage of completion. Stage of completion is determined
based on surveys of work performed as measured by units of production to date multiplied by contractually agreed-upon rates.

Hydraulic fracturing services: the revenue is recognized considering output methods, in particular surveys of service completion provided by the customer.

Revenue from providing services is recognized over time in the accounting period in which the
services are rendered.

The Company does not expect to have any contracts where the period between
the transfer of the promised goods or services to the customer and payment by the customer exceeds one year. As a consequence, considering
that the contracts do not include any significant financing component, the Company does not adjust any of the transaction prices for the
time value of money. For this reason, the Company is also applying the practical expedient not to disclose details on transaction prices
allocated to the remaining performance obligations as of the end of the reporting period.

Tenaris only provides standard quality warranties assuring that the goods
sold will function as expected or are fit for their intended purpose, with no incremental service to the customer. Accordingly, warranties
do not constitute a separate performance obligation.

Other revenues earned by Tenaris are recognized on the following basis:

| § | Interest income: on the effective yield basis. |

| § | Dividend income from investments in other companies: when Tenaris’s right to receive payment is 
 established.                                                                                    |
