NOTES TO THE CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS

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

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 July 31, 2019.

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.

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.

3        Segment information

Reportable operating segment

(All amounts in millions of U.S. dollars )

In the six-month period ended June 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 $14 million and $26 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.

Geographical information

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, 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.

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.

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. The Superior Court of Justice will review admissibility of CSN’s appeal, and, if declares it admissible, will 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.

Contingencies (Cont.)

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:

§   Ongoing investigation

The Company is aware that 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 controlled by an individual allegedly related with an officer of 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” and 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.

Contingencies (Cont.)

On January 22, 2016, Petroamazonas (“PAM”), an Ecuadorian state-owned oil company, imposed penalties to the Company’s Uruguayan subsidiary, Tenaris Global Services S.A. (“TGS”), for its alleged failure to comply with delivery terms under a pipe supply agreement. On June 27, 2018, TGS initiated arbitration proceedings against PAM before the Quito Chamber of Commerce Arbitration Center, seeking the annulment of the penalties. In September 2018, PAM filed its response to the arbitration claim. On May 16, 2019 the arbitration panel issued a favorable decision to TGS and decided that the penalties had been wrongfully imposed. The decision has now become final and TGS already collected the outstanding credits from PAM amounting to $22.5 million.

Tenaris Bay City Inc. (“Tenaris Bay City”), a U.S. subsidiary of the Company, received claims from a contractor for alleged additional costs in the construction of a project located in the Bay City area for an amount initially stated to be in excess of $90 million; however, subsequently the contractor amended the amount of the claim to $45 million plus attorneys’ fees and arbitration costs. On June 30, 2017, the contractor filed a demand for arbitration of these claims. On June 6, 2019, the arbitrators issued their final opinion, awarding $12.8 million to Brahma, inclusive of attorneys’ fees and interest. The parties agreed not to challenge the award and the Company paid the amount due on June 21, 2019.

§   Tax assessment in Mexico

In 2017, Tubos de Acero de México S.A (“Tamsa”) and Servicios Generales Tenaris Tamsa S.A (“Segeta”), two Mexican subsidiaries of the Company, were informed that the Mexican tax authorities had determined that the tax deductions associated with certain purchases of scrap made by the companies during 2013 failed to comply with applicable requirements and, accordingly, should be rejected. Tamsa and Segeta filed their respective responses and complaints against the determination and provided additional information evidencing compliance with applicable requirements for the challenged tax deductions. On August 30, 2018 and January 24, 2019, administrative decisions were issued in the proceedings against Segeta and Tamsa, respectively, determining a tax obligation in the amount of MXN1,540 million (approximately $80.4 million) for Segeta and MXN3,751 million (approximately $195.8 million) for Tamsa. On October 15, 2018 and March 8, 2019, Segeta and Tamsa filed revocation requests ( recursos de revocación exclusivos ) against the August 2018 decision as to Segeta, and the January 2019 decision as to Tamsa. On March 27, 2019, and July 1, 2019, respectively, Segeta and Tamsa were notified that the tax authorities had reversed and left without effects their former tax determinations and, accordingly both proceedings have been terminated.

§   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, 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 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.

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 million (approximately $7.6 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 BRL56.4 million (approximately $14.7 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:

Additionally Tenaris has issued performance guarantees mainly related to long term commercial contracts with several customers and parent companies guarantees for approximately $2.4 billion.

Restrictions to the distribution of profits and payment of dividends

As of June 30, 2019, Tenaris held 22% of Techgen’s share capital, and its affiliates, Ternium and Tecpetrol International S.A. (a wholly-owned subsidiary of San Faustin S.A., the controlling shareholder of both Tenaris and Ternium), held 48% and 30% respectively.

Techgen is a party to transportation capacity agreements for a purchasing capacity of 150,000 MMBtu/Gas per day starting on August 1, 2016 and ending on July 31, 2036, and a party to a contract for the purchase of power generation equipment and other services related to the equipment.

During 2019, there were repayments of loans by the shareholders of Techgen; the part corresponding to Tenaris amounted to $40.5 million. As of June 30, 2019, the aggregate outstanding principal amount under these subordinated loans was $58.1 million.

14       Investments in non-consolidated companies

On February 13, 2019, Techgen entered into a $640 million syndicated loan agreement with several banks to refinance an existing loan, resulting in the release of certain corporate guarantee issued by Techgen’s shareholders to secure the replaced facility.

Techgen’s obligations under the current facility, which is “non-recourse” on the sponsors, are guaranteed by a Mexican security trust covering Techgen’ shares, assets and accounts as well as Techgen’s affiliates rights under certain contracts. In addition, Techgen’s collection and payment accounts not subject to the trust have been pledged in favor of the lenders under the new loan agreement, and certain direct agreements –customary for these type of transactions– have been entered into with third parties and affiliates, including in connection with the agreements for the sale of energy produced by the project and the agreements for the provision of gas and long-term maintenance services to Techgen. The commercial terms and conditions governing the purchase, by the Company’s Mexican subsidiary Tamsa, of 22% of the energy generated by the project remain unchanged.

Under the loan agreement, Techgen is committed to maintain a debt service reserve account covering debt service becoming due during two consecutive quarters; such account is funded by stand-by letters of credit issued for the account of Techgen’s sponsors in proportion to their respective participations in Techgen. Accordingly, the Company and its Swiss subsidiary, Tenaris Investments Switzerland AG, applied for stand-by letters of credit covering 22% of the debt service coverage ratio, which as of the date hereof amounts to $9.8 million.

The application of the purchase method requires certain estimates and assumptions specially concerning the determination of the fair values of the acquired intangible assets and property, plant and equipment as well as the liabilities assumed at the date of the acquisition. The fair values determined at the acquisition date are based mainly on discounted cash flows and other valuation techniques.

The preliminary allocation of the fair values determined for the assets and liabilities arising from the acquisition is as follows:

Tenaris acquired 47.79% of total assets and liabilities shown above, approximately $109 million. As of the result of the acquisition, the Company recognized a Goodwill of approximately $32.5 million. Tenaris has chosen to recognize the non-controlling interest at the proportionate share of the acquiree’s net identifiable assets.

The acquired business contributed revenues for $86.8 million with a minor contribution to Tenaris’s margin for the period starting January 21, 2019 and ending June 30, 2019.

If the acquisition had occurred on 1 January 2019, consolidated revenue and profit after tax would have not changed significantly.

Following IFRS 3 “Business Combinations”, the Company will continue reviewing the allocation and make any necessary adjustments (mainly over property, plant and equipment, intangible assets and provisions) during the twelve months following the acquisition date.
