NOTES TO THE CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS

(In the notes all amounts are shown in U.S. dollars, unless otherwise stated)

1 General information

Tenaris S.A. (the "Company") was established as a public limited liability company (société anonyme) under the laws of the Grand-Duchy of Luxembourg on December 17, 2001. The Company holds, either directly or indirectly, controlling interests in various subsidiaries in the steel pipe manufacturing and distribution businesses. References in these Consolidated Condensed Interim Financial Statements to "Tenaris" refer to Tenaris S.A. and its consolidated subsidiaries. A list of the principal Company’s subsidiaries is included in Note 29 to the Company’s audited Consolidated Financial Statements for the year ended December 31, 2018.

The Company’s shares trade on the Buenos Aires Stock Exchange, the Italian Stock Exchange and the Mexican Stock Exchange; the Company’s American Depositary Securities (“ADS”) trade on the New York Stock Exchange.

These Consolidated Condensed Interim Financial Statements were approved for issuance by the Company’s Board of Directors on October 30, 2019.

2 Accounting policies and basis of presentation

These Consolidated Condensed Interim Financial Statements have been prepared in accordance with IAS 34, “Interim Financial Reporting”. The accounting policies used in the preparation of these Consolidated Condensed Interim Financial Statements are consistent with those used in the audited Consolidated Financial Statements for the year ended December 31, 2018 except for the adoption of new and amended standards as set out below. These Consolidated Condensed Interim Financial Statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2018, which have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standard Board (“IASB”) and in conformity with IFRS as adopted by the European Union (“EU”).

The preparation of Consolidated Condensed Interim Financial Statements requires management to make certain accounting estimates and assumptions that might affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the balance sheet dates, and the reported amounts of revenues and expenses for the reported periods. Actual results may differ from these estimates.

Material inter-company transactions, balances and unrealized gains (losses) on transactions between Tenaris’s subsidiaries have been eliminated in consolidation. However, since the functional currency of some subsidiaries is its respective local currency, some financial gains (losses) arising from inter-company transactions are generated. These are included in the Consolidated Condensed Interim Income Statement under Other financial results.

There were no significant changes in valuation techniques during the period and there have been no changes in any risk management policies since the year ended December 31, 2018.

Whenever necessary, certain comparative amounts have been reclassified to conform to changes in presentation in the current period.

Accounting pronouncements applicable as from January 1, 2019 and relevant for Tenaris

IFRS 16, “Leases”

Tenaris has adopted IFRS 16 “Leases” from 1 January 2019. In accordance with the transition provisions in IFRS 16, Tenaris has adopted the new rules using the modified retrospective approach, meaning that reclassifications of the adoption was recognized in the opening balance sheet as of January 1, 2019 and that comparatives were not restated.

Upon adoption of IFRS 16, Tenaris recognized lease liabilities in relation to leases which had previously been classified as ‘operating leases’ under the principles of IAS 17 “Leases”. These liabilities were measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as of 1 January 2019. The associated right-of-use assets were measured at the amount equal to the lease liability, adjusted by the amount of any prepaid or accrued lease payments relating to that lease recognized in the balance sheet as of December 31, 2018. The difference between the amount of the lease liability recognized in the statement of financial position at the date of initial application and the operating lease commitments under IAS 17 is related to leases with a duration lower than 12 months, low value leases and/or leases with clauses related to variable payments.

2. Accounting policies and basis of presentation (Cont.)

Accounting pronouncements applicable as from January 1, 2019 and relevant for Tenaris (Cont.)

IFRS 16, “Leases” (Cont.)

Leases are recognized as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the group. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The right-of-use asset is depreciated over the shorter of the asset's useful life and the lease term on a straight-line basis.

Lease liabilities include the net present value of i) fixed payments, less any lease incentives receivable, ii) variable lease payments that are based on an index or a rate, iii) amounts expected to be payable by the lessee under residual value guarantees, iv) the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and v) payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option.

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the lessee’s incremental borrowing rate is used, being the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions.

Right-of-use assets are measured at cost comprising the amount of the initial measurement of lease liability, any lease payments made at or before the commencement date less any lease incentives received and any initial direct costs incurred by the lessee.

Payments associated with short-term leases and leases of low-value assets are recognized on a straight-line basis as an expenses in profit or loss. Short-term leases are leases with a lease term of 12 months or less. Low-value comprise mainly IT equipment and small items of office furniture.

In determining the lease term, management considers all facts and circumstances that create an economic incentive to exercise an extension option, or not exercise a termination option. Extension options (or periods after termination options) are only included in the lease term if the lease is reasonably certain to be extended (or not terminated).

None of the accounting pronouncements issued after December 31, 2018 and as of the date of these Consolidated Condensed Interim Financial Statements has a material effect on the Company’s financial condition or result of operations.

In the nine-month period ended September 30, 2019 and 2018, transactions between segments, which were eliminated in consolidation, are mainly related to sales of scrap, energy, surplus raw materials and others from the Other segment to the Tubes segment for $26.3 million and $41.2 million respectively. In addition to the amounts reconciled above, the main differences in net income arise from the impact of functional currencies on financial result, deferred income taxes as well as the result of investment in non-consolidated companies and changes on the valuation of inventories according to cost estimation internally defined.

Allocation of net sales to geographical information is based on customer location. Allocation of depreciation and amortization is based on the geographical location of the underlying assets.

There are no revenues from external customers attributable to the Company’s country of incorporation (Luxembourg). For geographical information purposes, “North America” comprises Canada, Mexico and the USA; “South America” comprises principally Argentina, Brazil and Colombia; “Europe” comprises principally Italy, Romania and the United Kingdom; “Middle East and Africa” comprises principally Saudi Arabia, Kazakhstan, India, Nigeria and United Arab Emirates and “Asia Pacific” comprises principally China, Japan, Indonesia and Thailand.

Revenue is mainly recognized at a point in time to direct customers, when control has been transferred and there is no unfulfilled performance obligation that could affect the acceptance of the product by the customer. Tenaris’s revenues related to governmental institutions represent approximately 20% in 2019.

13 Contingencies, commitments and restrictions to the distribution of profits

Contingencies

Tenaris is from time to time subject to various claims, lawsuits and other legal proceedings, including customer claims, in which third parties are seeking payment for alleged damages, reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure.

Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, Tenaris is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the proceeding. In those cases, Tenaris has not accrued a provision for the potential outcome of these cases.

If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, Tenaris was able to make a reliable estimate of the expected loss or range of probable loss and has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice Tenaris’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss.

The Company believes that the aggregate provisions recorded for potential losses in these Consolidated Condensed Interim Financial Statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Tenaris could incur a charge to earnings which could have a material adverse effect on Tenaris’s results of operations, financial condition, net worth and cash flows.

Below is a summary description of Tenaris’s material legal proceedings which are outstanding as of the date of these Consolidated Condensed Interim Financial Statements. In addition, Tenaris is subject to other legal proceedings, none of which is believed to be material.

§ CSN claims relating to the January 2012 acquisition of Usiminas shares

Confab Industrial S.A. (“Confab”), a Brazilian subsidiary of the Company, is one of the defendants in a lawsuit filed in Brazil by Companhia Siderúrgica Nacional (CSN) and various entities affiliated with CSN against Confab and several Ternium subsidiaries that acquired a participation in Usiminas’ control group in January 2012.

The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas’ ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to Usiminas’ control group, and Confab would have a 17.9% share in that offer.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals maintained the understanding of the first instance court. On March 6, 2017, CSN filed a motion for clarification against the decision of the Court of Appeals of São Paulo, which was rejected on July 19, 2017. On August 18, 2017, CSN filed an appeal to the Superior Court of Justice seeking the review and reversal of the decision issued by the Court of Appeals. On March 5, 2018, the court of appeals ruled that CSN’s appeal did not meet the requirements for submission to the Superior Court of Justice and rejected the appeal. On May 8, 2018, CSN appealed against such ruling and on January 22, 2019, the court of appeals rejected it and ordered that the case be submitted to the Superior Court of Justice. On September 10, 2019, the Superior Court of Justice declared CSN’s appeal admissible. The Superior Court of Justice will review the case and then render a decision on the merits. The Superior Court of Justice is restricted to the analysis of alleged violations to federal laws and cannot assess matters of fact.

Tenaris continues to believe that all of CSN’s claims and allegations are groundless and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator (CVM) in February 2012 and December 2016, and the first and second instance court decisions referred to above.

§ Veracel celulose accident litigation

On September 21, 2007, an accident occurred in the premises of Veracel Celulose S.A. (“Veracel”) in connection with a rupture in one of the tanks used in an evaporation system manufactured by Confab. The Veracel accident allegedly resulted in material damages to Veracel. Itaú Seguros S.A. (“Itaú”), Veracel’s insurer at the time of the Veracel accident and then replaced by Chubb Seguros Brasil S/A (“Chubb”), initiated a lawsuit against Confab seeking reimbursement of damages paid to Veracel in connection with the Veracel accident. Veracel initiated a second lawsuit against Confab seeking reimbursement of the amount paid as insurance deductible with respect to the Veracel accident and other amounts not covered by insurance. Itaú and Veracel claimed that the Veracel accident was caused by failures and defects attributable to the evaporation system manufactured by Confab. Confab believes that the Veracel accident was caused by the improper handling by Veracel’s personnel of the equipment supplied by Confab in violation of Confab’s instructions. The two lawsuits were consolidated and are considered by the 6th Civil Court of São Caetano do Sul; however, each lawsuit will be adjudicated separately.

On September 28, 2018 Confab and Chubb, entered into a settlement agreement pursuant to which on October 9, 2018, Confab paid an amount of approximately $3.5 million to Chubb, without assuming any liability for the accident or the claim.

On October 10, 2018, Confab was notified that the court had issued rulings for both lawsuits. Both decisions were unfavorable to Confab:

§ With respect to Chubb’s claim, Confab was ordered to pay an amount of approximately BRL89.8 million (approximately $21.6 million) (including interest, fees and expenses). On October 15, 2018, Confab filed a request for homologation of the settlement agreement mentioned above, as such settlement agreement remains valid and binding between the parties. On November 8, 2018, the settlement agreement was homologated by the court.

§ With respect to Veracel’s claim, Confab was ordered to pay the insurance deductible and other concepts not covered by insurance, currently estimated to amount to BRL62 million (approximately $14.9 million) (including interest, fees and expenses). Both parties filed motions for clarification against the court’s decision, which were partially granted. Although the contract between Confab and Veracel expressly provided that Confab would not be liable for damages arising from lost profits, the court award would appear to include BRL53.2 million (approximately $12.8 million) of damages arising therefrom; Confab has additional defense arguments in respect of a claim for lost profits. On December 18, 2018, Confab filed an appeal against the first instance court decision, and on April 30, 2019, Veracel filed its response to the appeal. At this stage the Company cannot predict the outcome of the claim or the amount or range of loss in case of an unfavorable outcome.

§ Ongoing investigation

The Company is aware that Brazilian, Italian and Swiss authorities have been investigating whether certain payments were made from accounts of entities presumably associated with affiliates of the Company to accounts allegedly linked to individuals related to Petróleo Brasileiro S.A. and whether any such payments were intended to benefit the Company’s Brazilian subsidiary Confab. Any such payments could violate certain applicable laws, including the U.S. Foreign Corrupt Practices Act.

The Company had previously reviewed certain of these matters in connection with an investigation by the Brazilian authorities related to “Operation Lava Jato”, a new phase of which is presently ongoing.

The Audit Committee of the Company’s Board of Directors engaged external counsel in connection with a review of the alleged payments and related matters. In addition, the Company voluntarily notified the U.S Securities and Exchange Commission and the U.S. Department of Justice in October 2016.

In July 2019, the Company learned that the public prosecutor office of Milan, Italy, has completed a preliminary investigation into the alleged payments and has included in the investigation, among other persons, the Company’s Chairman and CEO, two other board members, Gianfelice Rocca and Roberto Bonatti, and the Company’s controlling shareholder, San Faustin. No determination has been made by the Italian judiciary as to whether to move the case to trial or have it dismissed.

The Company continues to review these matters and to respond to requests from and otherwise cooperate with the appropriate authorities. At this time, the Company cannot predict the outcome of these matters or estimate the range of potential loss or extent of risk, if any, to the Company's business that may result from resolution of these matters.

§ Putative class actions

Following the Company’s November 27, 2018 announcement that its Chairman and CEO Paolo Rocca had been included in an Argentine court investigation known as the Notebooks Case (a decision subsequently reversed by a higher court), two putative class action complaints were filed in the U.S. District Court for the Eastern District of New York. On April 29, 2019, the court consolidated the complaints into a single case, captioned “In re Tenaris S.A. Securities Litigation”, and appointed lead plaintiffs and lead counsel. On July 19, 2019, the lead plaintiffs filed an amended complaint purportedly on behalf of purchasers of Tenaris securities during the putative class period of May 1, 2014 through December 5, 2018. The individual defendants named in the complaint are Tenaris’s Chairman and CEO and Tenaris’s former CFO. The complaint alleges that during the class period, the Company and the individual defendants inflated the Tenaris share price by failing to disclose that sale proceeds received by Ternium (in which Tenaris held an 11.46% stake) when Sidor was expropriated by Venezuela were received or expedited as a result of allegedly improper payments made to Argentine officials. The complaint does not specify the damages that plaintiff is seeking. Management believes the Company has meritorious defenses to these claims; however, at this stage the Company cannot predict the outcome of the claim or the amount or range of loss in case of an unfavorable outcome.

§ Investigation concerning alleged price overcharges in Brazil

In 2018, two Brazilian subsidiaries of the Company were notified of formal charges arising from a review by the Tribunal de Contas da Uniao (TCU) for alleged price overcharges on goods supplied to Petróleo Brasileiro S.A- Petrobras under a supply contract. Both companies have already filed their defenses. The estimated amount of this claim is BRL29.2 million (approximately $7 million). Tenaris believes, based on the advice of counsel and external consultants, that the prices charged under the Petrobras contract do not result in overprices and that it is unlikely that the ultimate resolution of this matter will result in a material obligation.

§ 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 and is currently awaiting a resolution. In case of an unfavorable resolution, Confab may still appeal before the courts. The estimated amount of this claim is BRL56.6 million (approximately $13.6 million). At this stage, the Company cannot predict the outcome of this claim.

Commitments and guarantees

Set forth is a description of Tenaris’s main outstanding commitments:

§ A Tenaris company entered into a contract with Transportadora de Gas del Norte S.A. for the service of natural gas transportation to the facilities of Siderca, an Argentine subsidiary of Tenaris. As of September 30, 2019, the aggregate commitment to take or pay the committed volumes for a 9-year term totaled approximately $29.4 million.

§ Several Tenaris companies entered into a contract with Praxair S.A. for the service of oxygen and nitrogen supply. As of September 30, 2019, the aggregate commitment to take or pay the committed volumes for a 14-year term totalled approximately $55.2 million.

§ Several Tenaris companies entered into a contract with Graftech for the supply of graphite electrodes. As of September 30, 2019, the aggregate commitment to take or pay the committed volumes totalled approximately $43.5 million.

There were no transfers between Levels during the period.

The fair value of financial instruments traded in active markets is based on quoted market prices at the reporting date. A market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service, or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis. The quoted market price used for financial assets held by Tenaris is the current bid price. These instruments are included in Level 1 and comprise primarily corporate and sovereign debt securities.

The fair value of financial instruments that are not traded in an active market (such as certain debt securities, certificates of deposits with original maturity of more than three months, forward and interest rate derivative instruments) is determined by using valuation techniques which maximize the use of observable market data when available and rely as little as possible on entity specific estimates. If all significant inputs required to value an instrument are observable, the instrument is included in Level 2. Tenaris values its assets and liabilities included in this level using bid prices, interest rate curves, broker quotations, current exchange rates, forward rates and implied volatilities obtained from market contributors as of the valuation date.

The fair value of all outstanding derivatives is determined using specific pricing models that include inputs that are observable in the market or can be derived from or corroborated by observable data. The fair value of forward foreign exchange contracts is calculated as the net present value of the estimated future cash flows in each currency, based on observable yield curves, converted into U.S. dollars at the spot rate of the valuation date.

If one or more of the significant inputs are not based on observable market data, the instruments are included in Level 3. Tenaris values its assets and liabilities in this level using observable market inputs and management assumptions which reflect the Company’s best estimate on how market participants would price the asset or liability at measurement date. Main balances included in this level correspond to Tenaris’s interest in Venezuelan companies (see Note 15).

Borrowings are comprised primarily of fixed rate debt and variable rate debt with a short term portion where interest has already been fixed. They are classified under other financial liabilities and measured at their amortized cost. Tenaris estimates that the fair value of its main financial liabilities is approximately 99.1% of its carrying amount including interests accrued as of September 30, 2019 as compare with 99.3% as of December 31, 2018. Fair values were calculated using standard valuation techniques for floating rate instruments and comparable market rates for discounting flows.
