LETTER FROM THE CHAIRMAN 
 
2024 was a good year for Tenaris in many aspects. We consolidated our leading industry position with a 
number of distinct achievements, delivered solid financial results accompanied by higher returns for 
shareholders, and completed several investments which are improving our industrial efficiency and reducing 
our environmental footprint.  
 
It was, however, marred by an accident that took place at the end of the year which claimed the lives of two 
of our employees. The accident occurred in the heavy equipment maintenance shop of our main plant in 
Argentina. This is a major setback for Tenaris, which has an absolute commitment to safety with its 
employees and its communities. We deeply regret the loss of life and are reinforcing all our action on 
preventive activities with a focus on critical risks.  
 
For the year, our EBITDA reached $3.1 billion and net income $2.1 billion on net sales of $12.5 billion. Free 
cash flow amounted to $2.2 billion, all of which was distributed to shareholders through dividends and share 
buy backs. We are proposing to increase the annual dividend per share by 38% over that for the previous 
year. At the same time, we maintained our net cash position of $3.6 billion. 
 
In North America, consolidation among major shale operators has continued. We are strengthening our 
service differentiation with larger operators, who prize the operational efficiency, reliability and quality that 
we provide through our Rig Direct service. We now provide 24/7 digital well integrity solutions supported by 
technical specialists and remote monitoring capabilities in addition to our more established RunReady 
service and have extended our range of Wedge Series 400™ connections.  
 
ExxonMobil honored us with their 2024 supplier of the year award for our efforts in supply chain integration 
worldwide. We have served their operations in various parts of the world over many years and, since 2024, 
we have been serving all their US shale operations as well as their offshore operations in Guyana under long-
term agreements. 
 
We are establishing a leading position for 20K projects in the US deepwater. Shell recently awarded us the 
casing supply for the first wells in its Sparta project following many months of work on product testing and 
the development of 3D mapping technology that enhances pipe collapse resistance using Ultra High Collapse 
steel grades. This complements an award to supply BP’s Kaskida 20K project. 
 
We consolidated our leading position in the Guyana-Suriname basin with an award to supply line pipe and 
insulation coating for Total’s GranMorgu development. This achievement was possible thanks to our 
successful integration of Shawcor and its pipe coating technologies and project management capabilities.  
 
In the Middle East, our contributions to the development of local industrial capabilities are receiving 
recognition. In Saudi Arabia, we recently won a tender for a major CCS pipeline after Aramco had 
distinguished our GPC facility with a special quality award. In Abu Dhabi, we extended our long-term 
agreement with ADNOC, while our premium threading facility was certified as an Industry 4.0 digital leader 
by the Ministry of Industry and Advanced Technology.  
 
In Mexico, our sales have been affected by a steep decline in drilling activity amidst the financial difficulties of 
Pemex. We have, however, taken the opportunity to reduce our credit exposure. In Argentina, drilling activity 
and oil and gas production in Vaca Muerta is ramping up as pipeline and LNG infrastructure investment 
moves forward. Over the next months, we will be supplying the oil pipeline that will connect Vaca Muerta to 
a new deepwater port in Puerto Rosales in Chubut, while the activity ramp up will provide us the opportunity 
to increase our range of products and services.  
 
During the year, we completed several investments in our industrial system aimed at improving the efficiency 
of our operations as well as contributing to our decarbonization and environmental objectives. These include 
the installation of a new electric arc furnace with modern continuous charging technology in Argentina, the 
modernization of our Koppel steelmaking facility in the United States, and the installation of a new heat 
treatment furnace and finishing line at our Dalmine mill in Italy. We have also been investing to increase the 
level of automation and digital systems in our industrial and supply chain system and extend pipe by pipe 
traceability. 
 
We continue to make progress towards our target to reduce the carbon emissions of our operations. As the 
perimeter of our operations has expanded with recent acquisitions, we have decided to reset the baseline for 
our target to cover this expanded perimeter as well as to include inter-mill transportation and other changes 

Annual Report 2024

that enhance reporting transparency. Meanwhile, we are advancing with the construction of a second wind 
farm in Argentina and other investments aimed at increasing the share of renewable energy used in our 
operations. 
 
The impact of our community investments continues to grow as we focus on extending the reach of our 
technical education programs. Since we began offering technical training at the Roberto Rocca Technical 
School in Campana, in addition to its 450 pupils, the school gave courses to a further 1,400 members of the 
community in 2024. Similarly in Italy, we provided technical courses in our newly refurbished Fondazione 
Dalmine, equipped with robotics and automation laboratories, for 4,000 pupils from local schools. These 
training courses are designed to improve employment possibilities for members of the community.  
 
Looking ahead, with the change in the administration in the United States, we are heading into uncharted 
territory when it comes to geopolitics and the global trading system. Changes in tariffs and other events 
could significantly alter the established market environment. At the same time, the new administration has an 
agenda of extending American energy dominance and is changing the global focus of the energy transition. 
Tenaris, with its unique positioning, both globally and in North America, competitive differentiation and 
financial strength is well placed to navigate the uncertainties and opportunities ahead. 
 
Before closing, I would like to thank our CFO, Alicia Móndolo, for her contribution to Tenaris and the Techint 
Group over more than 40 years. I am very pleased that we will still be able to benefit from her wise advice in 
the time ahead.  
 
I would also like to thank all our employees for their constant commitment and engagement, without which 
the results and achievements of the past year would not have been possible, as well as our customers, 
suppliers and communities for their ongoing support. 
 
Sincerely,

RISK FACTORS 
 
You should carefully consider the risks and uncertainties described below, together with all other information 
contained in this annual report, before making any investment decision. Any of these risks and uncertainties 
could have a material adverse effect on our business, revenues, financial condition and results of operations, 
which could in turn affect the price of shares and ADSs. 
Risks Relating to Our Business and Industry 
 
Sales and profitability may fall as a result of downturns in the international price of oil and gas and other 
factors and circumstances affecting the oil and gas industry 
 
We are a global steel pipe manufacturer with a strong focus on manufacturing products and providing 
related services for the oil and gas industry. The oil and gas industry is a major consumer of steel pipe 
products worldwide, particularly for products manufactured under high quality standards and demanding 
specifications. Demand for steel pipe products from the oil and gas industry has historically been volatile and 
depends primarily upon the number of oil and natural gas wells being drilled, completed and reworked, and 
the depth, length and drilling conditions of these wells. The level of exploration, development and production 
activities of, and the corresponding capital spending by, oil and gas companies, including national oil 
companies, depends primarily on current and expected future prices of oil and natural gas and is sensitive to 
the industry’s view of future economic growth and the resulting impact on demand for oil and natural gas. 
Several factors, such as the supply and demand for oil and gas, the development and availability of new 
drilling technology, political and global economic conditions, and government regulations affect these prices. 
Among others, the following factors have had or are likely to have an impact on oil and gas prices: 
 
• 
drilling technology has allowed producers in the United States and Canada to increase production from 
their reserves of tight oil and shale gas in response to changes in market conditions more rapidly than in 
the past; 
 
• 
recent consolidation in the U.S. oil and gas industry has impacted prices and overall drilling activity in 
North America, which has now stabilized. For example, in 2023 ExxonMobil (“Exxon”) agreed to acquire 
Pioneer Natural Resources for approximately $60 billion, a transaction that has made Exxon the largest 
operator in the Permian Basin, the highest producing oil field in the United States; Chevron followed suit 
by striking a deal to acquire Hess in a $53 billion transaction that would provide the company with 
access to reserves in Guyana. Upstream operators such as Diamondback Energy, Inc. and ConocoPhillips 
have also made acquisitions over the past year to expand their North American footprint and shale 
inventory; 
 
• 
government initiatives to reduce GHG emissions, such as the introduction of a carbon tax or carbon-
pricing systems (such as the EU Carbon Border Adjustment Mechanism (“CBAM”)), the adoption of 
“cap-and-trade” systems (such as the EU Emissions Trading System (“ETS”)) or other measures to 
promote the use of renewable energy sources, or electric vehicles, could also affect oil and gas prices. 
For more information on risks relating to climate change regulations, see “Risk Factors - Risks Relating to 
Our Business and Industry - Climate change legislation and increasing regulatory requirements aimed at 
transitioning to a lower-carbon economy may reduce demand for our products and services and result in 
unexpected capital expenditures and costs, and negatively affect our reputation.” 
 
When the price of oil and gas falls, oil and gas companies generally reduce spending on production and 
exploration activities and, accordingly, make fewer purchases of steel pipe products. Major oil-and gas-
producing nations and companies have frequently collaborated to balance the supply (and thus the price) of 
oil in the international markets. A major vehicle for this collaboration has been the Organization of Petroleum 
Exporting Countries (“OPEC”) and many of our customers are state-owned companies in member countries 
of OPEC, which plays a significant role in trying to counter falling prices.

Climate change legislation and increasing regulatory requirements aimed at transitioning to a lower-carbon 
economy may reduce demand for our products and services and result in unexpected capital expenditures 
and costs, and negatively affect our reputation 
 
There is an increased attention on GHG emissions and climate change from different sectors of society. The 
Paris Agreement, adopted at the 2015 United Nations Climate Conference, sets out the global framework to 
limit the rising temperature of the planet and to strengthen the countries’ ability to deal with the effects of 
climate change. The EU ETS signaled a major EU energy policy to combat global warming based on a “cap & 
trade” program, and the European Green Deal, launched in 2019, focuses on adopting the required policies 
and measures aimed at reaching zero GHG emissions in Europe by 2050. The EU taxonomy classification 
system, which establishes a list of environmentally sustainable economic activities, is designed to help the EU 
scale up sustainable investment and implement the European Green Deal. In addition, the EU adopted the 
Corporate Sustainability Reporting Directive (“CSRD”), which requires European large and medium 
companies and listed issuers to disclose information on their risks and opportunities arising from social and 
environmental issues, and on the impacts of their activities on people and the environment and the 
Corporate Sustainability Due Diligence Directive (“CSDDD”), which mandates that companies operating 
within the EU identify, prevent, mitigate, and account for adverse human rights and environmental impacts in 
their operations and supply chains. Similarly, the EU CBAM, which was adopted on May 17, 2023, aims at 
promoting a reduction of emissions worldwide by subjecting the import of certain products, including steel, 
from countries outside of the EU to a carbon levy linked to the carbon price payable for goods produced in 
EU countries. For more information, see “Risk Factors - Risks Relating to Our Business and Industry - The cost 
of complying with environmental regulations and potential environmental and product liabilities may increase 
our operating costs and negatively impact our business, financial condition, results of operations and 
prospects”. However, certain EU member states, including Luxembourg, have not transposed the CSRD into 
national law by the required deadline and, therefore, the Company is not currently subject to CSRD and ESRS 
reporting requirements. Recently, in response to the need to strengthen the competitiveness of the EU 
economy, the European Commission (“EC”) has proposed to simplify sustainability reporting rules and boost 
investments through a package of proposed amendments to the CSRD, the EU Taxonomy, the CSDDD, the 
EU CBAM and current investment programs. If the proposed amendments are approved, Tenaris’s 
sustainability reporting and due diligence burdens may be reduced and simplified.  
 
In March 2024, the U.S. Securities and Exchange Commission (“SEC”) adopted climate-related disclosure 
rules that would have required registrants, including Tenaris from fiscal year 2025, to significantly expand the 
climate-related disclosures in their periodic reports, including information about climate-related risks that are 
reasonably likely to have a material impact on their business, results of operations, or financial condition, and 
certain climate-related financial statement metrics in a note to their audited financial statements. However, 
the implementation of this rule was voluntarily stayed by the SEC in April 2024, pending judicial review due 
to legal challenges and, on March 27, 2025, the SEC withdrew its legal defense of the climate change rule. 
Other countries are introducing or considering similar measures or regulations, which aim at lowering 
emissions or which enhance disclosure of climate-related matters, including carbon emissions. If there is no 
meaningful progress in lowering carbon emissions in the years ahead, there is an increased possibility of 
abrupt policy interventions as governments attempt to meet their environmental goals by adopting policy, 
legal, technology and market changes in the transition to a low-carbon global economy. 
 
The global regulatory landscape for Environmental, Social and Governance (“ESG”) is becoming increasingly 
complex, and jurisdictions in which we have operations have adopted or proposed laws, regulations and 
policies that diverge from, or potentially conflict with, those in other jurisdictions. In addition to laws, 
regulations and policies aimed at enhancing transparency and promoting sustainability-related practices, 
there has been an increase in regulatory activity against climate and diversity-related initiatives, which has led 
and may continue to lead to new laws, regulations and policies seeking to limit, discourage or prohibit such 
initiatives. Failure to comply with any legislation, regulation or policy, including as a result of good faith 
interpretations that may differ from those taken by enforcement authorities in relevant jurisdictions, could 
lead to substantial fines, regulatory sanctions, reputational damage and operational changes.

We provide products and services to the oil and gas industry, which accounts, directly and indirectly, for a 
significant portion of GHG emissions. Existing and future legislation and regulations related to GHG emissions 
(such as increased pricing of GHG emissions and enhanced emissions-reporting obligations) and climate 
change, as well as government initiatives to promote the use of alternative energy sources and substitute 
existing products and services with lower emissions options (with many jurisdictions implementing tax 
advantages and other subsidies to promote the development of renewable energy sources, or even requiring 
minimum thresholds for power generation from renewable sources), and the increased competitiveness of 
alternative sources of energy, may significantly curtail demand for and production of fossil fuels, such as oil 
and natural gas. These initiatives, together with the growing social awareness regarding climate change and 
other environmental matters, have resulted in increased investor and consumer demand for renewable 
energy and additional compliance requirements for fossil energy projects, which could become more 
stringent over time and to result in substantial increases in costs for the oil and natural gas industry, 
potentially leading to write-offs and early retirement of existing assets. Furthermore, ongoing technological 
developments in the renewable energy industry are making renewable energy increasingly competitive with 
fossil-fuels. If this trend continues, energy demand could shift increasingly towards more environmentally 
sustainable sources such as hydroelectrical, solar, wind and other renewable energies, which would, in turn, 
reduce demand for oil and natural gas, thus negatively affecting demand for our products and services and, 
ultimately, our future results of operations. In addition, adoption of new climate change legislation in the 
countries in which Tenaris operates could result in incremental operating costs (such as incremental 
compliance costs and increased insurance premiums) and unexpected capital expenditures and, eventually, 
affect our competitiveness and reduce our market share. Also, shifts in customer preferences and failure to 
respond to shareholders’ demand for climate-related measures and environmental standards could harm our 
reputation, adversely affect the ability or willingness of our customers or suppliers to do business with us, 
negatively impact workforce management and planning, erode stakeholder support and restrict or reduce 
access to financial resources. Moreover, our customers, investors, regulators, employees and other 
stakeholders have differing requirements, expectations, demands and perspectives on these topics, which are 
continuing to evolve and diverge. We may not be able to meet the differing requirements, expectations and 
demands of all of our stakeholders, which could harm our reputation, subject us to legal and operational 
risks, impact customer demand, and adversely impact our financial condition and operating results. For more 
information on Tenaris’s climate change initiatives, please see “Sustainability Statement - Environment - 
Climate Change”. 
  
The physical risks resulting from climate change, including extreme weather conditions and shifts in weather 
patterns, have in the past and may in the future adversely affect our operations and financial results 
 
Our business has been, and in the future could be, affected by severe weather in areas where we operate, 
which could materially affect our operations and financial results. Extreme weather conditions and natural 
disasters such as hurricanes, extreme wind, fires, flooding or coastal storm surges have resulted, and may in 
the future result, in the shutdown of our facilities, evacuation of our employees, and activity disruptions at 
our clients’ well-sites or in our supply chain. For example, the severe freeze in the United States and Mexico in 
early 2021, caused gas and power shortages in Texas, resulting in additional costs and production disruptions 
and losses. 
 
Chronic climate changes, such as changes in precipitation patterns and rises in average temperatures and sea 
levels, may result in increased operating costs or capital expenditures due to supply shortages or damage to 
facilities, higher insurance premiums or reduced availability of insurance, decreases in revenue derived from 
lower production capacity, and write-offs or early retirement of assets, all of which could adversely affect our 
financial condition, results of operations and cash flows. For more information on Tenaris’s climate change 
initiatives, please see “Sustainability Statement - Environment - Climate Change”.

Competition in the global market for steel pipe products may cause us to lose market share and hurt our 
sales and profitability 
 
The global market for steel pipe products is highly competitive, with the primary competitive factors being 
price, quality, service and technology. Over the past two decades, substantial investments have been made, 
especially in China but also in the United States and the Middle East, to increase production capacity of 
seamless steel pipe products, without a commensurate increase in overall demand, and as a result there is 
significant excess production capacity, particularly for “commodity” or standard product grades. Production 
capacity of more specialized product grades has also increased. At the same time, the high cost and long lead 
times required to develop the most complex projects, particularly deepwater projects, led to a slowdown in 
new developments in a context of low and more volatile oil prices. Despite our efforts to develop products 
and services that differentiate us from our competitors, the competitive environment is expected to remain 
intense in the coming years and our effective competitive differentiation, together with our ability to vertically 
integrate and to provide value added services, will be key success factors. In addition, there is a risk of unfairly 
traded steel pipe imports in markets in which Tenaris produces and sells its products, and we can give no 
assurance with respect to the application of antidumping duties and tariffs or the effectiveness of any such 
measures. 
 
Our sales may be affected as a result of antidumping and countervailing duty proceedings or by the 
imposition of other import restrictions or local content requirements 
 
Because of the global nature of our operations, we export and import products from several countries and, in 
many jurisdictions, we supplement domestic production with imported products. We import OCTG from 
Argentina and Mexico to complement our significant and growing production in the United States. From time 
to time, local producers seek the imposition of import restrictions or the initiation of antidumping or 
countervailing duty proceedings. For example, in October 2021, the U.S. Department of Commerce (“DOC”) 
initiated antidumping duty investigations of OCTG imports from Argentina, Mexico, and Russia and 
countervailing duty investigations of OCTG imports from Russia and South Korea, which resulted in a 
determination by the International Trade Commission (“ITC”), issued in October 2022, that the imports under 
investigation caused injury to the U.S. OCTG industry, bringing the investigation phase to a conclusion. 
Tenaris and other parties have appealed the agencies’ determinations from the investigation to the Court of 
International Trade, and, with respect to certain claims, to the Court of Appeals for the Federal Circuit. In 
addition, in response to a request from the Government of Argentina, the World Trade Organization 
(“WTO”) established a panel of experts to consider whether the DOC’s antidumping order applicable to 
Argentina is consistent with the international obligations of the United States. However, as a result of the 
investigation, and unless overturned on appeal, Tenaris is required to pay antidumping duty deposits until 
such time the imports are reviewed by the DOC to determine whether final duties are necessary for the 
specific period under review. For more information on this matter, please refer to note 27 “Contingencies, 
commitments and restrictions to the distribution of profits” to our audited consolidated financial statements 
included in this annual report. Antidumping or countervailing duty proceedings, any resulting penalties or any 
other form of import restriction have in the past impeded, and may in the future restrict, our access to 
important export markets for our products, thereby adversely impacting our sales or limiting our 
opportunities for growth. 
 
In addition, several jurisdictions have begun to impose or expand local content requirements. For example, in 
recent years Saudi Arabia has implemented various measures aimed at increasing local content particularly 
from suppliers to state-owned companies such as Saudi Arabian Oil Company (“Saudi Aramco”) and we can 
expect that measures favoring the development of local production will increase as Saudi Arabia seeks to 
create employment opportunities for its citizens and diversify its economy away from its dependence on oil 
and gas production. Other countries, such as Brazil, Ecuador, Indonesia, Nigeria and the United Arab 
Emirates, have also put in place significant local content requirements. Other mechanisms, such as CBAM, 
could have a similar impact. For more information, see “Risk Factors - Risks Relating to Our Business and 
Industry - The cost of complying with environmental regulations and potential environmental and product 
liabilities may increase our operating costs and negatively impact our business, financial condition, results of 
operations and prospects”. If countries impose or expand local content requirements or put in place 
regulations limiting our ability to import certain products, our competitive position could be negatively 
affected. Therefore, if any of these risks materialize, we may not continue to compete effectively against 
existing or potential producers and preserve our current shares of geographic or product markets, and 
increased competition may have a material impact on the pricing of our products and services, which could in 
turn adversely affect our revenues, profitability and financial condition.  
 
 

Annual Report 2024 
16 
Our sales may also be affected as a result of other international trade regulations 
 
The shipment of goods and services across international borders subjects us to extensive trade laws and 
regulations. Our import and export activities are governed by customs laws and regulations in each of the 
countries where we operate. Moreover, the EU, the United States and other countries control the import and 
export of certain goods and services and impose related import and export recordkeeping and reporting 
obligations. Those governments have also imposed economic sanctions against certain countries, persons and 
other entities, such as sanctions that restrict or prohibit transactions involving Iran, Syria, Venezuela and 
Russia or their citizens or companies. For more information on the impact on our business of the sanctions on 
Russia as a result of the armed conflict in Ukraine, see “Risk Factors - Risks Relating to Our Business and 
Industry - Armed conflicts, such as the Russia-Ukraine war, may adversely affect our operations”. Similarly, 
we are subject to the U.S. anti-boycott laws. Trade laws and regulations are complex and frequently 
changing, and they may be enacted, amended, enforced or interpreted in a manner that could materially 
impact our operations.  
 
In March 2018, under Section 232 of the Trade Expansion Act of 1962 (“Section 232”), the United States 
imposed a 25% tariff on steel articles imported from all countries, with the exemption of Canada and 
Mexico, as member states of the United States-Mexico-Canada Agreement (“USMCA”), and imports of steel 
tubes from Australia, Argentina, Brazil and South Korea (the latter three with specific quotas per product). 
The U.S. government granted successive exemptions on imports from Italy, Mexico, Romania and Argentina, 
of steel billets to be used at our Bay City mill, with the latest being granted in December 2023. Early in 2025, 
the U.S. government reset the Section 232 tariffs, imposing a 25% tariff on effectively all imports of steel and 
steel derivatives, revoking previously negotiated country-specific exemptions and quota arrangements. As a 
result, all previously exempted or quota-managed countries became subject to the full 25% tariff on their 
steel exports to the United States. These tariffs do not apply to imports of products with previously granted 
exclusions still in effect. In addition, on February 1, 2025, the U.S. government announced the imposition, 
through the International Emergency Economic Powers Act (“IEEPA”), of across-the-board tariffs applicable 
to all products imported from Mexico, Canada and China (with the exception, as of the date of this annual 
report, of Mexican and Canadian products that comply with USMCA preferential rules of origin). These tariffs 
and announced or potential retaliatory countermeasures from other countries or trade partners could affect 
market prices and dynamics, supply chains, and cost structures, and result in a prolonged or escalated trade 
war. 
 
Increases in the cost of raw materials, energy and other costs, limitations or disruptions to the supply of raw 
materials and energy, and price mismatches between raw materials and our products may hurt our 
profitability 
 
The manufacture of seamless steel pipe products requires substantial amounts of steelmaking raw materials 
and energy; welded steel pipe products, in turn, are processed from steel coils and plates. The availability and 
pricing of a significant portion of the raw materials and energy we require are subject to supply and demand 
conditions, which can be volatile, and to tariffs and other government regulations, which can affect 
continuity of supply and prices. In addition, disruptions, restrictions or limited availability of energy resources 
in markets where we have significant operations could lead to higher costs of production and eventually to 
production cutbacks at our facilities in such markets. For example, the start of the Russia–Ukraine war in 
2022, resulted in a spike in European energy costs, and, in early 2024, we experienced some delays in the 
delivery times to our customers in relation to orders that had to be diverted because of the ongoing shipping 
crisis in the Red Sea. 
At any given time, we may be unable to obtain an adequate supply of critical raw materials with price and 
other terms acceptable to us. The availability and prices of raw materials may also be negatively affected by 
new laws and regulations, including import controls, sanctions and other trade restrictions, allocation by 
suppliers, interruptions in production, accidents or natural disasters, armed conflicts, chronic climate change, 
changes in exchange rates, worldwide price fluctuations, and the availability and cost of transportation. For 
further information related to the impact on our business of the Russia-Ukraine war, see “Risk Factors – Risks 
Relating to Our Business and Industry – Armed conflicts, such as the Russia-Ukraine war, may adversely affect 
our operations”. Raw material and energy prices could also be affected by the introduction of carbon prices 
or taxes, or as a result of changes in production processes, such as an increased use of metal scrap, adopted 
by steelmaking companies seeking to reduce carbon emissions. In addition, we may not be able to recover, 
partially or fully, increased costs of raw materials and energy through increased selling prices for our 
products, or it may take an extended period of time to do so, and limited availability could force us to curtail 
production, which could adversely affect our sales and profitability. 
 
 

Annual Report 2024

Our results of operations and financial condition could be adversely affected by low levels of capacity 
utilization or failure to retain qualified workforce 
 
Like other manufacturers of steel-related products, we have fixed and semi-fixed costs (e.g., labor and other 
operating and maintenance costs) that cannot adjust rapidly to fluctuations in product demand for several 
reasons, including operational constraints and regulatory restrictions. If demand for our products falls 
significantly, or if we are unable to operate due to, for example, governmental measures or unavailability of 
workforce, these costs may adversely affect our profitability and financial condition. For example, in response 
to the abrupt and steep downturn of the oil and gas industry resulting from the oil crisis and the COVID-19 
pandemic in 2020, we were required to implement cost-containment measures and liquidity preservation 
initiatives, including reduction of our operating activities in several jurisdictions, temporary closure of 
facilities in the United States and review of our capital expenditure plans. Temporary suspensions of 
operations or closure of facilities generally lead to layoffs of employees, as was our case during the oil crisis 
and the COVID-19 pandemic, which may in turn give rise to labor conflicts and impact operations. Cost 
containment measures may also affect profitability and result in charges for asset impairments. In turn, in 
times of economic growth and high demand for our products we may not be able to retain qualified 
workforce or hire additional employees soon enough. For example, during the post-pandemic recovery 
period, when we brought production at our Bay City mill to full capacity, we faced some difficulties in hiring 
skilled workers. Moreover, certain consequences of climate change, such as shifts in customer preferences, 
stigmatization of our industry or failure to respond to shareholder demands for climate-related measures 
could negatively impact workforce management and planning, adversely affecting employee attraction and 
retention. 
 
Adverse economic or political conditions in the countries where we operate or sell our products and services 
may decrease our sales or disrupt our manufacturing operations, thereby adversely affecting our revenues, 
profitability and financial condition 
 
We have significant operations in various countries, including Argentina, Brazil, Canada, China, Colombia, 
Indonesia, Italy, Mexico, Nigeria, Romania, Saudi Arabia, the United Arab Emirates and the United States, and 
we sell our products and services throughout the world. Therefore, like other companies with worldwide 
operations, our business and operations have been, and could in the future be, affected from time to time to 
varying degrees by political, economic, social and public health developments and changes in laws and 
regulations. These developments and changes may include, among others, nationalization, expropriation or 
forced divestiture of assets; restrictions on production, imports and exports; antidumping or countervailing 
duties; travel, transportation or trade bans; interruptions in the supply of essential energy inputs; currency 
exchange and/or transfer restrictions, inability or increasing difficulties to repatriate income or capital or to 
make contract payments; inflation; devaluation; war or other armed conflicts (including the Russia-Ukraine 
war and regional conflicts in the Middle East and Africa); civil unrest and local security concerns, including 
high incidences of crime and violence involving drug trafficking organizations that threaten the safe 
operation of our facilities and operations; direct and indirect price controls; tax increases (including 
retroactive) and changes in the interpretation, application or enforcement of tax laws and other claims or 
challenges; cancellation of contract or property rights; and delays or denials of governmental approvals. Both 
the likelihood of such occurrences and their overall impact upon us vary greatly from country to country and 
are not predictable. Realization of these risks could have an adverse impact on the results of operations and 
financial condition of our subsidiaries located in the affected country and, depending on their materiality, on 
the results of operations and financial condition of Tenaris as a whole. 
More specifically, Argentina and Mexico are countries in which we have significant operations and relevant 
risks. 
 
 

Annual Report 2024

Our business and operations in Argentina may be materially and adversely affected by economic, political, 
social, fiscal and regulatory developments, including the following: 
• 
Macroeconomic and political conditions in Argentina may adversely affect our business and operations. 
In December 2023, a new administration, led by President Javier Milei, took office in Argentina and 
announced a series of emergency measures to address the critical economic situation. Some of those 
measures included deregulation efforts, cuts in public spending, including subsidies on public services, 
cut down on monetary issuance, increase of certain taxes, labor reforms, and the lifting of certain 
import restrictions and foreign exchange controls. It is uncertain the extent to which the Argentine 
government will be able to continue implementing its economic program and adopt major structural 
reforms. While the National Congress of Argentina approved some of the reforms submitted by the 
Milei administration in 2024, it is unclear whether Congress will endorse other major reforms, including 
labor and tax reforms. While the deregulation of the economy and intended reforms aim to create a 
more competitive and investment-friendly environment, the associated uncertainties and potential for 
abrupt policy changes pose substantial risks for companies operating in the country. In addition, 
conflicts between the national government and provincial governors, court decisions setting aside some 
of the governmental measures, resistance by social and union leaders and general social and political 
unrest may arise. Adverse economic and political conditions could cause a drop in demand for our 
products in the domestic market, adversely affecting our operations and financial results. Similarly, they 
could also negatively impact the business and operations of our customers (oil and gas companies 
operating in Argentina) and consequently our revenues and profitability. 
• 
Our business and operations in Argentina may be adversely affected by high inflation or by 
governmental measures to address inflation. In particular, increases in services and labor costs could 
affect cost-competitiveness and margins, negatively impacting our results of operations. An economic 
environment characterized by high inflation could undermine Argentina’s foreign competitiveness in 
international markets and negatively affect economic activity and employment levels. While inflation has 
falling significantly in recent months, failure to maintain low inflation rates could undermine Argentina’s 
foreign competitiveness in international markets and negatively affect economic activity and 
employment levels. In addition, if market volatility increases it may be impossible to estimate with 
reasonable certainty the extent to which our activity levels and results of operations could be affected in 
the future. In addition, an increased level of labor demands in response to spiraling inflation could 
trigger higher levels of labor conflict and, eventually, result in strikes or work stoppages involving our 
operations or those of our suppliers and customers. Any such disruption of operations could have an 
adverse effect on our operations and financial results. 
• 
Other events that may have an adverse effect on our operations and financial results include increased 
taxes, currency devaluation, exchange controls, restrictions on capital flows and export and import taxes 
or restrictions. Between September 2019 and December 2023, the Argentine government imposed 
significant restrictions on foreign exchange transactions. Although after a new administration took 
office in Argentina in December 2023 certain restrictions were eased and other changes to such 
regulations are expected, at the date of this annual report, the application of existing foreign exchange 
regulations remains uncertain, and the scope and timing of upcoming changes remain unknown. 
Currently, Argentine companies are required to repatriate export proceeds from sales of goods and 
services (including U.S. dollars obtained through advance payment and pre-financing facilities) and 
convert such proceeds into ARS at the official exchange rate. As from December 13, 2023, up to 20% 
of export proceeds can be sold for Argentine pesos through securities transactions resulting in a higher 
implicit exchange rate. This percentage has remained stable during the twelve-month period ended 
December 31, 2024, but it is unclear it will be further modified in the short term. Import payments for 
services rendered and goods cleared after December 12, 2023, do not require government approval but 
cannot be paid in advance or at sight and are subject to deferred payment schedules. In addition, during 
2024 import payments were subject to import taxes (which were eliminated in December 2024) that 
significantly increased prices of imported goods and services. Argentine companies must still obtain prior 
Argentine Central Bank authorization, which is rarely (if ever) granted, to access the foreign 
exchange market to make dividend payments. The existing measures limit the ability of Argentine 
companies to obtain foreign currency and make certain payments and distributions out of Argentina at 
the official exchange rate. If control systems are maintained or are not further eased, our operations 
could be adversely affected. In addition, the exchange rate of the Argentine peso against the U.S. dollar 
has devalued by more than 100% upon the change of government in December 2023. Since then, the 
new Administration has maintained a “crawling peg” policy by devaluating the Argentine currency at a 
rate of approximately 2% per month, reduced to 1% per month as of February 1, 2025. The extent and 
rate of the crawling peg remains unclear. In the event of an additional devaluation, our Argentine 

Annual Report 2024 
19 
subsidiaries, which hold U.S. dollar-denominated Argentine bonds, may be adversely affected, and will 
also suffer a loss on deferred tax charges as a result of a deterioration of the tax value of their fixed 
assets. At this time, the Company is unable to estimate all impacts of a new devaluation of the 
Argentine peso against the U.S. dollar. For additional information on current Argentine exchange 
controls and restrictions, see “Legal and Financial Information - Additional Information – Exchange 
Controls” and note 29 “Foreign exchange control measures in Argentina” of our audited consolidated 
financial statements included in this annual report. Given that the volatile and uncertain environment 
remains as of the date of this annual report, additional regulations or restrictions could further restrict 
our ability to access the official foreign exchange market, expose us to the risk of losses arising from 
fluctuations in the exchange rate between the ARS and the USD, cause disruptions to our operations 
due to lack of imported raw materials and other inputs, affect our ability to finance and even carry out 
major investments in Argentina, and/or impair our ability to convert and transfer outside the country 
funds generated by Argentine subsidiaries to pay dividends or royalties or make other offshore 
payments. 
• 
In recent years, our operations in Argentina experienced constraints in their electricity and natural gas 
supply requirements on many occasions. Shortages of energy and natural gas in Argentina have led in 
the past (and could lead in the future) to production cutbacks that could negatively affect our revenues 
and profitability; we could also face increased costs when using alternative sources of energy. 
In Mexico, our business could be materially and adversely affected by economic, political, social, fiscal and 
regulatory developments, including the following: 
 
• 
The Mexican government exercises significant influence over the Mexican economy and, therefore, 
governmental actions concerning the economy and state-owned enterprises could have a significant 
impact on Mexico’s private sector and on our Mexican-related operations.  
• 
We maintain a strong, longstanding relationship with Petróleos Mexicanos (“Pemex”), one of the 
world’s largest crude oil and condensates producers and one of our largest customers. Over the past 
several months, Pemex has delayed payments beyond the agreed-upon due dates, resulting in a 
significant credit exposure to Pemex, which represented approximately 17% of our overall credit 
exposure as of December 31, 2024. In December 2024, Pemex issued senior guaranteed floating rate 
notes due in 2025 that a financial institution purchased on the issue date, with Pemex agreeing to use a 
portion of the proceeds from the sale of such notes to pay off outstanding debt with one of the 
Company’s Mexican subsidiaries for approximately $200 million. The fee related to this transaction, 
amounting to approximately to $16 million, was borne by the Company. If Pemex defaults on its 
payment obligations or we increase our exposure to Pemex, our revenues and profitability would be 
adversely affected. A similar collection transaction occurred in early 2025. 
• 
Our Mexican operations could also be affected by criminal violence, primarily due to the activities of 
drug cartels and related organized crime which has been increasing in Mexico over the last years. 
Although the Mexican government has implemented various security measures and has strengthened its 
military and police forces, drug-related crime continues to exist in Mexico. Our business may be 
materially and adversely affected by these activities, their possible escalation and the violence associated 
with them. 
• 
In the last few years, the Mexican government has made, and has attempted to make, various 
amendments to energy rules and regulations that impact energy supply and cost structure. Since 
December 2018, the Mexican government has been introducing changes to electricity regulations, 
including amendments to the Energy Industry Law (“LIE”), and a bill to reform the Constitution, which 
was rejected by the Mexican Congress in 2021. These changes aimed to grant priority to Mexico’s state-
owned electric power generation and distribution company Comisión Federal de Electricidad (“CFE”), 
over private generators in the supply of electric power to the Mexican market and mandated a revision 
of power generation and transaction agreements between CFE and independent electric power 
suppliers. The intended reforms were challenged in court and, in January 2024, the Supreme Court 
ruled against the constitutionality of certain provisions of the LIE reform. In response, the Mexican 
President announced a new proposal for an ambitious constitutional reform, which covers a wide range 
of topics, including energy matters. During 2024, the Mexican Congress approved several constitutional 
reforms aimed at restructuring the judicial system and increasing state control over key sectors, including 
energy, telecommunications, and natural resources. For example, changes have been introduced to the 
constitutional status of CFE and Pemex, resulting in increased government intervention in their policies 
at the expense of their boards’ independence. This increased regulatory oversight has led to a more 

Annual Report 2024 
20 
unpredictable business environment. In particular, the energy reform has introduced significant 
regulatory and legal uncertainties for energy companies, affecting their operations, financial 
performance, and strategic planning. Companies have had to navigate a complex and evolving 
regulatory landscape, invest in compliance programs, and reassess their investment strategies to mitigate 
the risks associated with these reforms. Uncertainty remains as to whether the Mexican government or 
any of its decentralized bodies will introduce new reforms to the energy market or adopt any measure 
that may further affect the energy supply or increase its cost. Any such new amendment or measures 
could negatively affect the operations of Tubos de Acero de Mexico S.A. (“Tamsa”) or Techgen S.A. de 
C.V. (“Techgen”), the power plant in which Tenaris holds a 22% equity interest and which supplies 
electricity for most of our Mexican operations. At this stage, we cannot assess the potential effects of 
any new governmental initiative on the Mexican economy in general, and particularly on our local 
operations and, consequently, on the results of operations and financial conditions of our businesses in 
Mexico. 
• 
In the past, our operations in Mexico were disrupted due to union-led stoppages resulting from an 
internal dispute within the local union. Although our Mexican operations have not experienced any 
further disruptions caused by employee stoppages since 2020, we cannot assure that further disruptions 
will not occur in the future. Any future stoppage, strike, disruption of operations or new collective 
bargaining agreements could result in lost sales and could increase our costs, thereby affecting our 
results of operations. 
 
Armed conflicts, such as the Russia-Ukraine war, may adversely affect our operations 
 
In response to the start of the Russia-Ukraine war in February, 2022, the United States, the EU and the United 
Kingdom (the “UK”), among other countries, imposed a wave of sanctions against certain Russian 
institutions, companies and citizens. The Russian Government has retaliated by banning airlines from its 
airspace and has ordered economic counter measures, including restrictions on residents transferring foreign 
currency abroad. It has been three years since the Russia-Ukraine war began and any resolution and timing 
thereof still remains uncertain. Russia is a major supplier of oil and gas in Europe and worldwide, and Russia 
and Ukraine are both major global suppliers of internationally traded steelmaking raw materials and semi-
finished steel products. As a result of the war and related sanctions, energy and commodity prices spiked 
upwards and foreign trade transactions involving Russian and Ukrainian counterparties have been severely 
affected. A long-standing conflict makes it hard to predict how energy and commodity prices will continue to 
behave as higher prices and possible shortages of energy and raw materials used in our steelmaking 
operations (including natural gas and electric energy, particularly in Europe, steel scrap, pig iron, direct 
reduced iron (“DRI”), hot briquetted iron (“HBI”), ferroalloys, steel bars, coils and plates) would result in 
higher production costs and potential plant stoppages, affecting our profitability and results of operations. As 
a result of existing or future economic sanctions imposed on Russia, we or our contractors (including shipping 
companies) may not be able to continue purchasing products from, or making payments to, Ukrainian or 
Russian suppliers or counterparties; and we may not be able to promptly procure such raw materials from 
other suppliers, or we may be required to purchase raw materials at increased prices.  
 
We have suspended any sales to Russian customers or purchases from Russian suppliers that would breach 
applicable sanctions, and we have closed our representative office in Moscow. Furthermore, in March 2022, 
we recorded an impairment in the amount of approximately $14.9 million, fully impairing our investment in 
our joint venture in Russia with Severstal. 
 
Other ongoing armed conflicts, including the Middle East conflict and the ongoing shipping crisis in the Red 
Sea, may disrupt our operations, increase our costs, and adversely affect our delivery times. 
 
 

Annual Report 2024

If we do not successfully implement our business strategy, our ability to grow, our competitive position and 
our sales and profitability may suffer 
We plan to continue implementing our business strategy of consolidating our position as a leading global 
supplier of integrated product and service solutions to the energy and other industries and adapting to the 
energy transition through reducing the carbon emissions in our operations and developing and supplying 
products and services for low-carbon energy applications, as well as continuing to pursue strategic 
investment opportunities. Any of the components of our overall business strategy could cost more than 
anticipated (including as a result of increasing regulatory requirements aimed at transitioning to a lower-
carbon economy), may not be successfully implemented or could be delayed or abandoned. For example, we 
may fail to create sufficient differentiation in our Rig Direct® services to offset the added costs of providing 
such services, or fail to find suitable investment opportunities, including acquisition targets that enable us to 
continue to grow and maintain or improve our competitive position.  
 
In addition, acquisitions may be subject to challenges or investigations by governmental authorities, including 
antitrust and consumer-protection authorities. The costs of complying with authorization or investigation 
procedures may be significant. Also, antitrust authorities are looking very closely at the effects of acquisitions 
and may deny authorizations, impose conditions that may result in significant costs or deprive Tenaris of the 
advantages and expected synergies of acquisitions, or initiate investigation upon challenges brought by third 
parties. Challenges to acquisitions or other investments, and failure to obtain, or conditions imposed for the 
granting of, authorizations may prevent or delay transactions, which could have an adverse effect on our 
financial condition and results of operations. 
 
Even if we successfully implement our business strategy, it may not yield the expected results, or decisions by 
our joint venture partners may frustrate our initiatives. For example, in 2022 we had to terminate our joint 
venture with JFE Holdings Inc. (“JFE”) with respect to NKKTubes K.K. (“NKKTubes”) when JFE decided to 
close down operations at one of its steel complexes.  
 
Future acquisitions, strategic partnerships and capital investments may not perform in accordance with 
expectations or may disrupt our operations and hurt our profits 
One element of our business strategy is to identify and pursue growth-enhancing strategic opportunities. As 
part of that strategy, we regularly make significant capital investments and acquire interests in, or businesses 
of, various companies. Consistent with our growth strategy, we intend to continue considering strategic 
acquisitions, investments and partnerships from time to time to expand our operations and establish a local 
presence in our markets. We must necessarily base any assessment of potential acquisitions, joint ventures 
and capital investments on assumptions with respect to timing, profitability, market and customer behavior 
and other matters that may subsequently prove to be incorrect. Our past or future acquisitions, significant 
investments and alliances may not perform in accordance with our expectations and could adversely affect 
our operations and profitability. In addition, new demands on our existing organization and personnel 
resulting from the integration of new acquisitions could disrupt our operations and adversely affect our 
operations and profitability. Moreover, as part of future acquisitions, we may acquire assets that are 
unrelated to our business, and we may not be able to integrate these assets or sell them under favorable 
terms and conditions. 
Disruptions to our manufacturing processes could adversely impact our operations, affect customer service 
levels or our reputation, or expose us to liability and, consequently, adversely affect our financial results 
Our steel pipe manufacturing processes depend on the operation of critical steelmaking equipment, such as 
electric arc furnaces (“EAF”), continuous casters, rolling mills, heat treatment and various operations that 
support them, such as our power generation facilities. Despite the investments we make to maintain critical 
production equipment, such equipment may incur downtime as a result of unanticipated failures or other 
events, such as fires, explosions, floods, earthquakes, accidents and severe weather conditions.

Similarly, natural disasters or severe weather conditions, including those related to climate change, could 
significantly damage our production facilities and general infrastructure or affect the normal course of 
business. For example, our Mexican production facility located in Veracruz is located in a region prone to 
earthquakes, and our Bay City facility in Texas, United States is located in an area prone to strong winds and 
hurricanes, and occasional floods. More generally, changing weather patterns and climatic conditions in 
recent years have added to the unpredictability and frequency of natural disasters. For more information on 
the risks associated with climate-change, see “Risk Factors - Risks Relating to Our Business and Industry - The 
physical risks resulting from climate change, including extreme weather conditions and shifts in weather 
patterns, have in the past and may in the future adversely affect our operations and financial results”. 
 
Our operations may also be adversely affected as a result of work stoppages or other labor conflicts. In the 
past, our operations in Mexico were disrupted due to union-led stoppages resulting from an internal dispute 
within the local union. Although our Mexican operations have not experienced any further disruptions caused 
by employee stoppages since 2020, we cannot assure that further disruptions will not occur in the future. In 
addition, in some of the countries in which we have significant production facilities (e.g., Argentina and 
Brazil), significant inflationary pressures and higher tax burdens could increase labor demands and could 
eventually generate higher levels of labor conflicts, which may result in operational disruptions.  
In addition, epidemics and other public health crises may disrupt our operations, as was the case during 2020 
as a result of the COVID-19 outbreak when some of our facilities or production lines were closed or 
shutdown.  
 
Some of the previously described emergency situations could result, and in some cases have resulted, in 
damage to property, delays in production or shipments and death or injury to persons. 
Any of the foregoing could expose us to liability and affect our reputation. To the extent that lost production 
or delays in shipments cannot be compensated for by unaffected facilities, such events could have an adverse 
effect on our profitability and financial condition. Additionally, we do not carry business interruption 
insurance, and the insurance we maintain for property damage and general liability may not be adequate or 
available to protect us under such events, its coverage may be limited, or the amount of our insurance may 
be less than the related loss. For more information on our insurance coverage, see “Information on the 
Company - Business overview - Insurance”.  
 
We may be required to record a significant charge to earnings if we must reassess our goodwill or other 
assets as a result of changes in assumptions underlying the carrying value of certain assets, particularly as a 
consequence of deteriorating market conditions  
Assets that are subject to amortization are reviewed for impairment whenever events or changes in 
circumstances indicate that the carrying amount may not be recoverable. Intangible assets with indefinite 
useful life, including goodwill, are subject to impairment tests following IAS 36. Impairment tests have 
resulted in impairment charges. Impairment charges for the last three years are shown below: 
  
• 
In March 2022, in light of the Russia-Ukraine war and the designation of Severstal’s controlling 
shareholder as a person subject to EU and UK sanctions, we recorded an impairment in the amount of 
approximately $14.9 million, fully impairing our investment in our joint venture in Russia with 
Severstal. For more information on Tenaris’s operations involving Russia, see “Risk Factors - Risks 
Relating to Our Business and Industry - Armed conflicts, such as the Russia-Ukraine war, may adversely 
affect our operations”. 
 
• 
In September 2022, mainly due to the lower expectations for steel demand and market steel prices in 
Brazil, together with a worsened global macroeconomic situation that derived in an increase in discount 
rates, we wrote down our investment in Usinas Siderúrgicas de Minas Gerais S.A.(“Usiminas”) by $19.1 
million, and in September 2023, we recorded a net loss of $25.5 million, related to the participation 
increase in Usiminas. 
 
• 
In December 2022, in the presence of impairment indicators, the Company conducted impairment tests, 
reviewed the values of certain idle assets in its subsidiaries and recorded impairment charges of $76.7 
million. 
 
 

Annual Report 2024 
23 
As of December 31, 2024, goodwill amounted to $1,090 million corresponding mainly ($920 million) to the 
acquisition of Hydril Company (“Hydril”) in 2007 and is allocated to Hydril, Siderca and Tamsa cash 
generating units (“CGU”). 
 
For more information on impairment charges, please refer to note 5 “Impairment charge”, note 8 “Equity in 
earnings of non-consolidated companies” and note 14 “Investments in non-consolidated companies” to 
our audited consolidated financial statements included in this annual report.  
 
Our results of operations and financial condition could be adversely affected by movements in exchange rates 
As a global company, we manufacture and sell products throughout the world and a portion of our business 
is carried out in currencies other than the U.S. dollar, which is the Company’s functional and presentation 
currency. As a result, we are exposed to foreign exchange rate risk. Changes in currency values and foreign 
exchange regulations could adversely affect our financial condition and results of operations. For information 
on our foreign exchange rate risk, please see “Legal and Financial Information - Quantitative and Qualitative 
Disclosure About Market Risk”. 
Changes in applicable tax regulations and resolutions of tax disputes could negatively affect our financial 
results 
We are subject to tax laws in numerous foreign jurisdictions where we operate. The integrated nature of our 
worldwide operations can produce conflicting claims from revenue authorities in different countries as to the 
profits to be taxed in the individual countries, including disputes relating to transfer pricing. Most of the 
jurisdictions in which we operate have double tax treaties with foreign jurisdictions, which provide a 
framework for mitigating the risk of double taxation on our results. However, in case double taxation persists, 
dispute resolution mechanisms developed to resolve such conflicting claims are largely untried and can be 
expected to be very lengthy.  
 
In recent years, tax authorities around the world have increased their scrutiny of companies’ tax filings and 
have become more rigid in exercising any discretion they may have. As part of this, in 2015, the Organization 
for Economic Co-operation and Development (“OECD”) proposed a number of tax law changes under its 
Base Erosion and Profit Shifting (“BEPS”) action plans to address issues of base erosion transparency, 
coherence and substance. Most of the countries in which we operate have already implemented some of 
those changes within their own domestic tax legislations. 
In 2019, the OECD launched a new initiative on behalf of the G20 (“OECD/G20 Inclusive Framework on 
BEPS”) under the format of a two pillars solution: Pillar One, aimed at minimizing profit shifting by working 
towards a coordinated global tax framework that reallocates taxing rights over a portion of the profits of 
large and profitable multinational entities to market jurisdictions, ensuring that corporate income taxes are 
paid where consumption takes place, and Pillar Two, aimed at introducing a global standard on minimum 
taxation, both combined with new tax dispute resolution processes. This project achieved OECD political 
consensus in October 2021. 
In December 2021, the OECD released the Pillar Two model rules (the Global Anti-Base Erosion rules, or 
“GloBE”) to reform international corporate taxation. Following Pillar Two OECD’s initiative, the EU adopted in 
December 2022 a directive to impose a global minimum taxation for multinational companies in the Union, 
effective as from January 1, 2024. 
On December 20, 2023, the Luxembourg Parliament approved the Pillar Two law transposing the EU Pillar 
Two Directive into domestic legislation. The law took effect for fiscal years commencing on or after December 
31, 2023. 
The Company is within the scope of these rules, and therefore is required to calculate its GloBE effective tax 
rate for each jurisdiction where it operates and is liable to pay a top-up tax for the difference between its 
GloBE effective tax rate per jurisdiction and the 15% minimum rate. 
While the implementation of the Pillar Two project is underway in many countries, negotiations among the 
respective countries regarding Pillar One implementation details have not yet concluded, and therefore, it is 
not yet clear when it will be fully in effect. 
 
 

Annual Report 2024 
24 
The EC adopted in 2016 its Anti-Tax Avoidance Directive (“ATAD”), later expanded by ATAD 2, which seeks 
to prevent tax avoidance by companies and to ensure that companies pay appropriate taxes in the markets 
where profits are effectively made, and business is effectively performed. In addition, the EC drafted a 
directive aiming to avoid the use of shell entities (ATAD 3), which is still under discussion.  
On January 20, 2025, the United States announced that it would withdraw from the OECD Global Tax Deal 
and that any prior commitments made by the United States will no longer have any force or effect. The 
memorandum announcing the withdrawal also directed the U.S. Secretary of the Treasury to develop and 
deliver to President Trump, within 60 days, a list of protective measures or other options towards foreign 
countries that are either not in compliance with any tax treaty with the United States or have, or are likely to 
have, tax rules that are extraterritorial or disproportionately affect U.S. companies. 
Changes to tax laws and regulations in the countries where we operate require us to continually assess our 
organizational structure and could lead to increased risk of international tax disputes. 
 
Our interpretation and application of the tax laws could differ from that of the relevant governmental taxing 
authority, which could result in the payment of additional taxes, penalties or interest, negatively affecting our 
profitability and financial condition. Significant uncertainties remain in relation to the potential adoption of 
the new regulations that might result from evolving initiatives like those launched by the OECD and the EU in 
relation to international taxation that could impact negatively our financial condition, results of operations 
and cash flows. 
If we do not comply with laws and regulations designed to combat corruption in countries in which we sell 
our products, we could become subject to governmental investigations, fines, penalties or other sanctions 
and to private lawsuits and our sales and profitability could suffer 
We operate and conduct business globally, including in certain countries known to experience high levels of 
corruption. Although we are committed to conducting business in a legal and ethical manner in compliance 
with local and international statutory requirements and standards applicable to our business, there is a risk 
that our employees, representatives, associates, affiliates, or other persons may take actions that violate 
applicable laws and regulations that generally prohibit offering or making of improper payments to any 
individual, including to government officials, for the purpose of obtaining a benefit or undue advantage or 
keeping business, as stated by the U.S. Foreign Corrupt Practices Act (“FCPA”) and other anti-corruption laws 
adopted by the main countries in which we operate, which impose strict criminal liability on companies for 
corrupt practices undertaken by their employees or representatives. In addition, we cannot give any assurance 
that we will detect all illegal activity that may have been conducted in the past at any acquired business. 
Investigations by government authorities may occupy considerable management time and attention, weaken 
company compliance culture and result in significant expenditures, fines, penalties or other sanctions, as well 
as private lawsuits. For information on matters related to the Company Business Conduct Compliance 
Program, please refer to our website on the matter https://www.tenaris.com/en/sustainability/governance-
and-ethics/. Information contained in or otherwise accessible through our Internet website is not a part of this 
annual report. 
For example, upon learning of a government investigation as to whether certain payments had been made 
prior to 2014 from accounts of entities presumably associated with affiliates of the Company to accounts 
allegedly linked to individuals related to Petróleo Brasileiro S.A. (“Petrobras”) and whether any such payments 
were intended to benefit Confab Industrial S.A. (“Confab”), the Audit Committee of the Company's board of 
directors engaged external counsel in connection with the Company’s review of these matters. In addition, 
the Company voluntarily notified the SEC and the U.S. Department of Justice (“DOJ”) in October 2016, and 
conducted, with the assistance of external counsel, an internal investigation and found no evidence 
corroborating any involvement by the Company or its directors, officers or employees in respect of improper 
payments. On June 2, 2022, the Company resolved the investigation by the SEC and the DOJ informed that it 
had closed its parallel inquiry without taking action. Under the settlement with the SEC, the Company neither 
admitted nor denied the SEC’s findings and on June 24, 2022, paid $53.1 million in disgorgement and 
prejudgment interest and $25 million as a civil penalty to conclude the matter. With respect to the same 
matter, Confab is subject to civil claims from Petrobras and the Brazilian public prosecutors (who seek 
damages for approximately $31.2 million and a prohibition from contracting with, or receiving benefits or 
exemptions from, the Brazilian state for an unspecified term) and to administrative responsibility proceedings 
before Brazil’s General Controllers’ Office. Although Confab believes that the allegations are groundless and 
is contesting these claims, the Company cannot predict the outcome of these proceedings at this stage.

“Contingencies, commitments and restrictions of profits” to our audited consolidated financial statements 
included in this annual report. 
The cost of complying with environmental regulations and potential environmental and product liabilities may 
increase our operating costs and negatively impact our business, financial condition, results of operations and 
prospects 
We are subject to a wide range of local, state, provincial and national laws, local and international 
regulations, permit requirements and decrees relating to the protection of human health and the 
environment, including laws and regulations relating to hazardous materials and radioactive materials and 
environmental protection governing air emissions, water discharges and waste management. Laws and 
regulations protecting the environment have become increasingly complex and more stringent and expensive 
to implement in recent years. Additionally, international environmental requirements vary. While standards in 
the EU, Canada, and Japan are generally comparable to (or more stringent than) U.S. standards, other 
nations, particularly developing nations, including China, have substantially fewer or less rigorous 
requirements that may give competitors in such nations a competitive advantage. It is possible that any 
international agreement to regulate emissions may provide exemptions and lesser standards for developing 
nations. In such case, we may be at a competitive disadvantage relative to competitors having more or all of 
their production in such developing nations. 
Environmental laws and regulations may, in some cases, impose strict liability rendering a person liable for 
damages to natural resources or threats to public health and safety without regard to negligence or fault. 
Some environmental laws provide for joint and several strict liability for remediation of spills and releases of 
hazardous substances. These laws and regulations may expose us to liability for the conduct of or conditions 
caused by others or for acts that were in compliance with all applicable laws at the time they were 
performed. 
Compliance with applicable requirements and the adoption of new requirements could have a material 
adverse effect on our consolidated financial condition, results of operations or cash flows. The costs and 
ultimate impact of complying with environmental laws and regulations are not always clearly known or 
determinable since regulations under some of these laws have not yet been promulgated or are undergoing 
revision. The expenditures necessary to remain in compliance with these laws and regulations, including site 
or other remediation costs, or costs incurred as a result of potential violations of environmental laws could 
have a material adverse effect on our financial condition and profitability. While we incur and will continue to 
incur expenditures to comply with applicable laws and regulations, there always remains a risk that 
environmental incidents or accidents may occur that may negatively affect our reputation or our operations. 
The EU CBAM aims at promoting emissions reductions worldwide by subjecting the import of certain 
products, including steel, from countries outside of the EU to a carbon levy linked to the carbon price payable 
for goods produced in EU countries. CBAM entered into application in its transitional phase, on October 1, 
2023, with the first reporting period for importers ending January 31, 2024. Starting on January 1, 2026, the 
CBAM will enter into full force and importers will need to obtain an authorization to import goods covered 
by the CBAM, make annual statements on the quantity of goods imported into the EU and their embedded 
GHG emissions and purchase certificates to cover their declared emissions. Recently, in response to the need 
to strengthen the competitiveness of the EU economy, the EC has proposed certain changes to simplify and 
facilitate compliance with CBAM obligations (including simplification of the authorization of declarants, the 
calculation of emissions and the management of financial liability). 
Our oil and gas casing, tubing and line pipe products are sold primarily for use in oil and gas drilling, 
gathering, transportation, processing and power generation facilities, which are subject to inherent risks, 
including well failures, line pipe leaks, blowouts, bursts and fires, that could result in death, personal injury, 
property damage, environmental pollution or loss of production. Any of these hazards and risks can result in 
environmental liabilities, personal injury claims and property damage from the release of hydrocarbons. 
Defects in specialty tubing products could result in death, personal injury, property damage, environmental 
pollution, damage to equipment and facilities or loss of production.  
 

Annual Report 2024 
26 
We normally warrant the oilfield products and specialty tubing products we sell or distribute in accordance 
with customer specifications, but as we pursue our business strategy of providing customers with additional 
services, such as Rig Direct®, we may be required to warrant that the goods we sell and services we provide 
are fit for their intended purpose. Actual or claimed defects in our products may give rise to claims against us 
for losses suffered by our customers and expose us to claims for damages. The insurance we maintain will not 
be available in cases of gross negligence or willful misconduct, in other cases may not be adequate or 
available to protect us in the event of a claim, its coverage may be limited, canceled, or otherwise terminated, 
or the amount of our insurance may be less than the related impact on enterprise value after a loss. Similarly, 
our sales of tubes and components for the automotive industry subject us to potential product liability risks 
that could extend to being held liable for the costs of the recall of automobiles sold by car manufacturers and 
their distributors. 
Limitations on our ability to protect our intellectual property rights, including our trade secrets, could cause a 
loss in revenue and any competitive advantage we hold 
Some of our products or services, and the processes we use to produce or provide them, have been granted 
patent protection, have patent applications pending, or are trade secrets. Our business may be adversely 
affected if our patents are unenforceable, the claims allowed under our patents are not sufficient to protect 
our technology, our patent applications are denied, or our trade secrets are not adequately protected. Our 
competitors may be able to independently develop technology that is similar to ours without infringing on 
our patents or gaining access to our trade secrets, which could adversely affect our financial condition, results 
of operations and cash flows.  
 
Cyberattacks could have a material adverse impact on our business and results of operations 
We rely heavily on information systems to conduct our operations, and digital technologies have an 
increasingly significant role across our business. Although we devote significant resources to protect our 
systems and data and we continually monitor and evaluate the actual or potential impact of external 
developments and available information on threats and security incidents, we have experienced and expect to 
continue to experience varying degrees of cyber incidents in the normal conduct of our business, which may 
occasionally include sophisticated cybersecurity threats such as unauthorized access to data and systems, loss 
or destruction of data, computer viruses or other malicious code, phishing, ransomware, spoofing, 
cyberattacks and/or cybersecurity risks arising from service providers. These threats often arise from numerous 
sources, not all of which are within our control, such as fraud or malice from third parties, including fraud 
involving business email compromises, failures of computer servers or other accidental technological failures, 
electrical or telecommunication outages or other damage to our property or assets. 
 
Cybersecurity threats represent one of the most significant risks for most businesses. Cyberattack attempts 
continued to increase throughout 2024, and the development and wide availability of artificial intelligence 
(“AI”) has increased the number, scope and chances of success of such attacks. 
 
According to the World Economic Forum’s 2025 Global Cybersecurity Outlook (“WEF”), cybercrime grew in 
both frequency and sophistication, marked by ransomware attacks, AI-enhanced tactics – such as phishing, 
vishing and deepfakes – and a notable increase in supply chain attacks. Some 72% of respondents report an 
increase in organizational cyber risks, with ransomware remaining a top concern. Nearly 47% of 
organizations cite adversarial advances powered by generative AI (“GenAI”) as their primary concern, 
enabling more sophisticated and scalable attacks. In 2024 there was a sharp increase in phishing and social 
engineering attacks, with 42% of organizations reporting such incidents. 
 
Additionally, Microsoft has reported a 2.75 times increase in human-operated ransomware attacks, where 
the most prevalent initial access techniques were social engineering -specifically phishing through email and 
other channels-, identity compromise, exploiting vulnerabilities of systems exposed to the internet, and 
unpatched operating systems. 
 
In addition, emerging technologies, such as GenAI, which are becoming available more widely and faster, are 
expected to exacerbate cyber resilience challenges. Approximately half of executives surveyed at the World 
Economic Forum’s annual meeting on cybersecurity stated that advances in adversarial capabilities (phishing, 
malware, deepfakes) present the most concerning impact of generative AI on cyber and fewer than one in 
ten respondents believe that in the next two years generative AI will give the advantage to defenders over 
attackers. 
 
 

Annual Report 2024 
27 
In 2024, we continued improving cybersecurity controls, processes and procedures to monitor, detect, assess, 
respond to and recover from hacking, malware infections, cybersecurity compromises and other risks; with 
the aim of increasing our cyber resilience. In addition, we continued with cybersecurity awareness and ethical 
phishing campaigns aimed at protecting us against cyberthreats, and tailored cybersecurity training programs 
addressed to our executives and employees. We have also instructed our employees not to submit 
confidential information to any AI that is not approved by Tenaris. 
 
Given the rapidly evolving nature of cyberthreats, and particularly as the adoption of AI tools becomes more 
relevant to Tenaris operations, there can be no assurance that the systems we have designed to prevent or 
limit the effects of cyber incidents or attacks will be adequate, and such incidents or attacks could have a 
material adverse impact on our systems. While we attempt to mitigate these risks, we remain vulnerable to 
additional known or unknown threats, including theft, misplacement or loss of data, programming errors, 
employee errors and/or dishonest behavior that could potentially lead to the compromising of sensitive 
information, improper use of our systems or networks, as well as unauthorized access, use, disclosure, 
modification or destruction of such information, systems and/or networks.  
 
Furthermore, the increasing complexity of supply chains poses an additional cybersecurity risk, considering 
software vulnerabilities and the risk of propagation of cyberattacks throughout Tenaris’s ecosystem, including 
suppliers, service providers and customers. There is no assurance that the systems implemented by third 
parties will be effective, and Tenaris cannot fully control the exposure to failures or breaches of such 
systems. If critical suppliers, service providers, customers or other relevant third parties become subject to 
cyberattacks, depending on their scope and success, Tenaris’s information or systems may be compromised 
and, eventually, such third parties may be unable to provide key services or supplies, thus affecting our 
activities and operations.  
 
If our systems for protecting against cybersecurity risks (or cybersecurity measures implemented by our 
suppliers, service providers and customers) are circumvented or breached, this could also result in disruptions 
to our business operations (including but not limited to, defective products, production downtimes or loss of 
productivity), access to our financial reporting systems, the loss of access to critical data or systems, misuse or 
corruption of critical data and proprietary information (including our intellectual property and customer data), 
as well as damage to our reputation with our customers and the market, failure to meet customer 
requirements, customer dissatisfaction and/or regulatory fines and penalties (including for inadequate 
protection of personal data and/or failure to notify the competent authorities for such breach), damages and 
harm to the environment and people, or other financial costs and losses. In addition, given that cybersecurity 
threats continue to evolve, we will be required to devote additional resources in the future to enhance our 
protective measures or to investigate and/or remediate any cybersecurity vulnerabilities. Additionally, 
although we periodically consider cyber insurance coverage options, we do not currently maintain 
cybersecurity insurance, and the insurance we carry for property damage and general liability may not be 
adequate or available to protect us from damages derived from cyberthreats or coverage may be 
limited. Moreover, any investigation of a cyberattack would take time before completion, during which we 
would not necessarily know the extent of the actual or potential harm or how best to remediate it, and 
certain errors or actions could be repeated or compounded before duly discovered and remediated (all or any 
of which could further increase the costs and consequences arising out of such cyberattack). In addition, 
failure to adequately and timely monitor and evaluate our hardware and software systems and applications to 
prevent or manage technology obsolescence risks may result in increased costs, the operational risk of service 
failure, and the loss of technology competitiveness and reputation. 
 
Furthermore, in response to the increase in the number and sophistication of ransomware attacks, U.S. and 
regulatory agencies have implemented regulations to prevent victims from making ransomware payments 
and to deter third parties from facilitating or processing such payments to cyber actors, which would 
constrain our ability to deal with ransomware attacks, should they occur.

Risks Relating to the Structure of the Company  
The Company’s dividend payments depend on the results of operations and financial condition of its 
subsidiaries and could be restricted by legal, contractual or other limitations or tax changes 
The Company is a holding company and conducts all its operations through subsidiaries. Dividends or other 
intercompany transfers of funds from those subsidiaries are the Company’s primary source of funds to pay its 
expenses, debt service and dividends and to repurchase shares or ADSs. 
The ability of the Company’s subsidiaries to pay dividends and make other payments to us will depend on 
their results of operations and financial condition. If earnings and cash flows of the Company’s operating 
subsidiaries are substantially reduced, the Company may not be in a position to meet its operational needs or 
to pay dividends. In addition, such dividends and other payments could be restricted by applicable corporate 
and other laws and regulations, including those imposing foreign exchange controls or restrictions on the 
repatriation of capital or the making of dividend payments, and agreements and commitments of such 
subsidiaries. For information concerning potential restrictions on our ability to collect dividends from certain 
subsidiaries, see “Risk Factors – Risks Relating to Our Business and Industry – Adverse economic or political 
conditions in the countries where we operate or sell our products and services may decrease our sales or 
disrupt our manufacturing operations, thereby adversely affecting our revenues, profitability and financial 
condition” and “Financial Information – Consolidated Statements and Other Financial Information – Dividend 
Policy”. 
The Company’s ability to pay dividends to shareholders is subject to legal and other requirements and 
restrictions in effect at the holding company level. For example, the Company may only pay dividends out of 
net profits, retained earnings and distributable reserves and premiums, each as defined and calculated in 
accordance with Luxembourg law and regulations. In addition, the Company’s dividend distributions (which 
are currently imputed to a special tax reserve and are therefore not subject to Luxembourg withholding tax) 
may be subject to Luxembourg withholding tax if current Luxembourg tax law were to change. 
The Company’s controlling shareholder may be able to take actions that do not reflect the will or best 
interests of other shareholders 
As of December 31, 2024, San Faustin beneficially owned 61.37% of the Company’s issued share capital, 
and 65.81% of the voting rights. San Faustin’s share percentage ownership and voting rights increased 
following the cancellation of the shares repurchased by the Company under its share buyback program, 
approved at the extraordinary general meeting of shareholders, held on April 30, 2024. San Faustin’s share 
percentage ownership and voting rights will increase further if the cancellation of the shares repurchased by 
the Company under its share buyback programs is approved at the upcoming extraordinary general meeting 
of shareholders, scheduled to be held on May 6, 2025. Rocca & Partners Stichting Administratiekantoor 
Aandelen San Faustin (“RP STAK”) holds voting rights in San Faustin sufficient to control San Faustin. As a 
result, RP STAK is indirectly able to elect a substantial majority of the members of the Company’s board of 
directors and has the power to determine the outcome of most actions requiring shareholder approval, 
including, subject to the requirements of Luxembourg law, the payment of dividends. The decisions of the 
controlling shareholder may not reflect the will or best interest of other shareholders. In addition, the 
Company’s articles of association permit the Company’s board of directors to waive, limit or suppress 
preemptive rights in certain cases. Accordingly, the Company’s controlling shareholder may cause its board of 
directors to approve in certain cases an issuance of shares for consideration without preemptive rights, 
thereby diluting the minority interest in the Company. See “Risk Factors – Risks Relating to shares and ADSs – 
Holders of shares and ADSs in the United States may not be able to exercise preemptive rights in certain 
cases”.  
 
 

Annual Report 2024 
29 
Risks Relating to Shares and ADSs  
Holders of shares or ADSs may not have access to as much information about the Company as they would in 
the case of a U.S. domestic issuer 
There may be less publicly available information about the Company than is regularly published by or about 
U.S. domestic issuers. Also, corporate and securities regulations governing Luxembourg companies may not 
be as extensive as those in effect in other jurisdictions and U.S. securities regulations applicable to foreign 
private issuers, such as the Company, differ in certain respects from those applicable to U.S. domestic issuers. 
Furthermore, IFRS, the accounting standards in accordance with which the Company prepares its 
consolidated financial statements, differ in certain material aspects from U.S. GAAP. For a summary of the 
significant ways in which the Company’s corporate governance practices differ from the corporate 
governance standards required for domestic companies by the New York Stock Exchange (“NYSE”), see 
“Information on the Company - Corporate Governance Statement – Summary of differences with NYSE 
standards”. 
Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights 
afforded to shareholders 
Certain shareholders’ rights under Luxembourg law, including the rights to participate and vote at general 
meetings of shareholders, to include items on the agenda for the general meetings of shareholders, to 
receive dividends and distributions, to bring actions, to examine our books and records and to exercise 
appraisal rights may not be available to holders of ADSs, or may be subject to restrictions and special 
procedures for their exercise, as holders of ADSs only have those rights that are expressly granted to them in 
the deposit agreement. Deutsche Bank Trust Company Americas, as depositary under the ADS deposit 
agreement (“the Depositary”), through its custodian agent, is the registered shareholder of the deposited 
shares underlying the ADSs, and therefore only the Depositary can exercise the shareholders’ rights in 
connection with the deposited shares. For example, if the Company makes a distribution in the form of 
securities, the Depositary is allowed, at its discretion, to sell the right to acquire those securities on your 
behalf and to instead distribute the net proceeds to you. Also, under certain circumstances, such as the 
Company’s failure to provide the Depositary with voting materials on a timely basis, you may not be able to 
vote at general meetings of shareholders by giving instructions to the Depositary. If the Depositary does not 
receive voting instructions from the holder of ADSs by the prescribed deadline, or the instructions are not in 
proper form, then the Depositary shall deem such holder of ADSs to have instructed the Depositary to vote 
the underlying shares represented by ADSs in favor of any proposals or recommendations of the Company 
(including any recommendation by the Company to vote such underlying shares on any given issue in 
accordance with the majority shareholder vote on that issue), for which purposes the Depositary shall issue a 
proxy to a person appointed by the Company to vote such underlying shares represented by ADSs in favor of 
any proposals or recommendations of the Company. Under the ADS deposit agreement, no instruction shall 
be deemed given and no proxy shall be given with respect to any matter as to which the Company informs 
the Depositary that (i) it does not wish such proxy given, (ii) it has knowledge that substantial opposition 
exists with respect to the action to be taken at the meeting, or (iii) the matter materially and adversely affects 
the rights of the holders of ADSs.  
Holders of shares and ADSs in the United States may not be able to exercise preemptive rights in certain 
cases 
Pursuant to Luxembourg corporate law, existing shareholders of the Company are generally entitled to 
preferential subscription rights (preemptive rights) in the event of capital increases and issues of shares 
against cash contributions. Under the Company’s articles of association, the board of directors has been 
authorized to waive, limit or suppress such preemptive subscription rights. Notwithstanding the waiver of any 
preemptive subscription rights, any issuance of shares for cash within the limits of the authorized share 
capital shall be subject to the preemptive subscription rights of existing shareholders, except (i) any issuance 
of shares (including without limitation, the direct issuance of shares or upon the exercise of options, rights 
convertible into shares, or similar instruments convertible or exchangeable into shares) against a contribution 
other than in cash; and (ii) any issuance of shares (including by way of free shares or at discount), up to an 
amount of 1.5% of the issued share capital of the Company, to directors, officers, agents, employees of the 
Company, its direct or indirect subsidiaries or its affiliates (or, collectively, the beneficiaries), including without 
limitation, the direct issuance of shares or upon the exercise of options, rights convertible into shares or 
similar instruments convertible or exchangeable into shares, issued for the purpose of compensation or 
incentive of the beneficiaries or in relation thereto (which the board of directors shall be authorized to issue 

Annual Report 2024

upon such terms and conditions as it deems fit). For further details, see “Information on the Company - 
Corporate Governance Statement – Corporate Governance”. 
Holders of ADSs in the United States may, in any event, not be able to exercise any preemptive rights, if 
granted, for shares underlying their ADSs unless additional shares and ADSs are registered under the U.S. 
Securities Act of 1933, as amended, (“Securities Act”), with respect to those rights, or an exemption from 
the registration requirements of the Securities Act is available. The Company intends to evaluate, at the time 
of any rights offering, the costs and potential liabilities associated with the exercise by holders of shares and 
ADSs of the preemptive rights for shares, and any other factors it considers appropriate at the time, and then 
to make a decision as to whether to register additional shares. The Company may decide not to register any 
additional shares, requiring a sale by the Depositary of the holders’ rights and a distribution of the proceeds 
thereof. Should the Depositary not be permitted or otherwise be unable to sell preemptive rights, the rights 
may be allowed to lapse with no consideration to be received by the holders of the ADSs.  
It may be difficult to obtain or enforce judgments against the Company outside Luxembourg 
The Company is a société anonyme organized under the laws of the Grand Duchy of Luxembourg, and most 
of its assets are located in other jurisdictions. Furthermore, most of the Company’s directors and officers 
reside in other jurisdictions. As a result, investors may not be able to effect service of process upon the 
Company or its directors or officers. Investors may also not be able to enforce against the Company or its 
directors or officers in the investors’ domestic courts, judgments predicated upon the civil liability provisions 
of the domestic laws of the investors’ home countries. Likewise, it may be difficult for investors not domiciled 
in Luxembourg to bring an original action in a Luxembourg court predicated upon the civil liability provisions 
of other securities laws, including U.S. federal securities laws, against the Company, its directors or its 
officers. There is also uncertainty with regard to the enforceability of original actions of civil liabilities 
predicated upon the civil liability provisions of securities laws, including U.S. federal securities laws, outside 
the jurisdiction where such judgments have been rendered; and enforceability will be subject to compliance 
with procedural requirements under applicable local law, including the condition that the judgment does not 
violate the public policy of the applicable jurisdiction.

Business Overview 
Our business strategy is to consolidate our position as a leading global supplier of integrated product and 
service solutions to the energy and other industries and to adapt to the energy transition through reducing 
the carbon emissions in our operations and on developing and supplying products and services for low-
carbon energy applications by: 
• 
pursuing strategic investment opportunities in order to further strengthen our presence in local and 
global markets and expand our range of products and services; 
 
• 
expanding our comprehensive range of products and developing new products designed to meet the 
needs of customers operating in challenging environments, including low carbon energy applications, 
such as hydrogen and CCS; 
 
• 
enhancing our offering of services, including technical, digital and supply chain integration services 
designed to enable customers to optimize well planning and integrity, simplify operations and reduce 
overall operating costs; and 
 
• 
securing an adequate supply of production inputs and reducing the manufacturing costs and carbon 
intensity of our core products. 
Pursuing strategic investment opportunities and alliances 
We have a solid record of growth through strategic investments and acquisitions. We pursue selective 
strategic investments and acquisitions as a means to expand our operations and presence in select markets, 
expand our range of products and services and enhance our global competitive position and capitalize on 
potential operational synergies. At the end of 2023, for example, we acquired the global pipe coating 
business of Mattr, which has enhanced our range of pipe coating technologies and reinforced our capability 
to provide integrated pipe and coating solutions for offshore pipelines. 
Expanding our range of products including the development of new products for the energy transition 
We have developed an extensive range of high-value products suitable for most of our customers’ operations 
using our network of specialized R&D facilities and by investing in our manufacturing facilities. As our 
customers expand their operations, we seek to supply high-value products that reduce costs and enable them 
to operate safely in challenging environments, including those for low-carbon applications associated with 
the energy transition. 
As suppliers of tubular products and services to the energy industry, the energy transition currently underway 
provides an important opportunity to develop new products and services for potentially fast-growing 
segments like hydrogen transportation and storage, CCS and geothermal installations. We have developed a 
range of technologies that are particularly suited for use in hydrogen storage and transportation, where we 
have seen growth in demand for large, high-pressure vessels used in the build out of hydrogen refueling 
stations for heavy-duty vehicles and buses in Europe and California. We are also seeing increasing interest 
from customers for developing CCS and geothermal projects. 
Enhancing our offering of technical, digital and supply chain integration services - Rig Direct® - and extending 
their global deployment 
We continue to enhance our offering of Rig Direct® services and extend their deployment worldwide. For 
many years, we have provided these services, managing customer inventories and directly supplying pipes to 
their rigs on a just-in-time basis, complemented by technical advice and assistance on the selection of 
materials and their use in the field, in markets like Mexico and Argentina. In response to changes in market 
conditions and the increased focus of customers on reducing costs and improving the efficiency of their 
operations, the extent and deployment of our Rig Direct® services has been extended throughout North 
America and in other markets around the world (e.g., Colombia, North Sea, Romania and the United Arab 
Emirates) and now include digital and more extensive supply chain integration services. Through the provision 
of Rig Direct® services, we seek to integrate our operations with those of our customers using digital 
technologies to shorten the supply chain and simplify operational and administrative processes, as well as 
technical services for well planning and well integrity, to reduce costs, improve safety and minimize

36 
environmental impact. They are also intended to differentiate us from our competitors and further strengthen 
our relationships with customers worldwide under long-term agreements. 
Securing inputs for our manufacturing operations 
We seek to secure our existing sources of raw material and energy inputs, and to gain access to new sources 
of low-cost inputs which can help us maintain or reduce the cost of manufacturing our core products and 
reduce the carbon emissions intensity of our operations over the long term. We aim to achieve a vertically 
integrated value chain for our production. To this end, we purchase most of our supplies through Exiros, a 
specialized procurement company the ownership of which we share with Ternium. Exiros offers us integral 
procurement solutions, supplier sourcing activities; category organized purchasing; suppliers’ performance 
administration; and inventory management.

Business Segments 
Tenaris has one major business segment, “Tubes”, which is also the reportable operating segment. All other 
business activities and operating segments that are not required to be separately reported, are disclosed in 
the “Others” segment.  
The Tubes segment includes the production and sale of steel tubular products and related services mainly for 
the oil and gas industry, particularly OCTG used in drilling operations, line pipe used in transportation and 
processing activities and mechanical and structural tubes for other industrial applications, with production 
processes that consist in the production and transformation of steel into tubular products. Business activities 
included in this segment are mainly dependent on the worldwide oil and gas industry, as this industry is a 
major consumer of steel pipe products, particularly OCTG used in drilling activities. Demand for steel pipe 
products from the oil and gas industry has historically been volatile and depends primarily upon the number 
of oil and natural gas wells being drilled, completed and reworked, and the depth and drilling conditions of 
these wells. Major oil and gas companies have adapted their strategies and allocated investments in 
renewable energies in response to the energy transition while maintaining their capability to meet market 
demand for oil and gas and reducing the emissions from their operations. As the energy transition advances, 
demand for our products and services from low-carbon energy applications, such as geothermal, hydrogen 
and CCS, is expected to increase while demand for oil and gas applications may decrease. 
Sales are generally made to end users, with exports being done through a centrally managed global 
distribution network and domestic sales are made through local subsidiaries. 
The Other segment includes all business activities related to oilfield / hydraulic fracturing services, and the 
production and selling of sucker rods, coiled tubing, tubes used for plumbing and construction applications 
and others as energy and raw materials that exceed internal requirements. 
For more information on our business segments, see “II C. Accounting Policies - Segment information” to our 
audited consolidated financial statements included in this annual report.

Our Products 
Our principal finished products are seamless and welded steel casing and tubing, line pipe and various other 
mechanical and structural steel pipes for different uses. Casing and tubing are also known as OCTG. We 
manufacture our steel pipe products in a wide range of specifications, which vary in diameter, length, 
thickness, finishing, steel grades, coating, threading and coupling. For more complex applications, including 
high pressure and high temperature applications, seamless steel pipes are usually specified and, for some 
standard applications, welded steel pipes can also be used. In addition to oil and gas applications, many of 
our products can also be used in low-carbon energy applications, such as geothermal, hydrogen and CCS. 
Casing. Steel casing is used to sustain the walls of oil and gas wells during and after drilling. 
Tubing. Steel tubing is used to conduct crude oil and natural gas to the surface after drilling has been 
completed. 
Line pipe. Steel line pipe is used to transport crude oil and natural gas from wells to refineries, storage tanks 
and loading and distribution centers. 
Mechanical and structural pipes. Mechanical and structural pipes are used by general industry for various 
applications, including the transportation of other forms of gas and liquids under high pressure. 
Cold-drawn pipe. The cold-drawing process permits the production of pipes with the diameter and wall 
thickness required for use in boilers, superheaters, condensers, heat exchangers, automobile production and 
several other industrial applications. 
Premium joints and couplings. Premium joints and couplings are specially designed connections used to join 
lengths of steel casing and tubing for use in high temperature or high pressure environments. A significant 
portion of our steel casing and tubing products are supplied with premium joints and couplings. We own an 
extensive range of premium connections, and following the integration of the premium connections business 
of Hydril, we have marketed our premium connection products under the “TenarisHydril” brand name. In 
addition, we hold licensing rights to manufacture and sell the “Atlas Bradford” range of premium 
connections outside the United States and we own the “Ultra” and “TORQ” ranges of premium connections. 
Pipe coatings. Concrete weight, anti-corrosion, thermal insulation and flow assurance coatings for offshore 
and onshore pipelines. 
Coiled tubing. Coiled tubing is used for oil and gas drilling and well workovers and for subsea pipelines. 
Other products and services. We also manufacture sucker rods used in oil extraction activities, tubes used for 
plumbing and construction applications, oilfield / hydraulic fracturing services and we engage in other 
activities, such as the sale of energy and raw materials that exceed our internal requirements.

equipment and make-up facilities; 
• 
a cold-drawing mill; and 
• 
a port on the Paraná river for the supply of raw materials and the shipment of finished products. 
Our local electric energy requirements are satisfied through a 100 MW wind farm, which required an 
investment of approximately $200 million and, since October 2023 has supplied close to 50% of the energy 
requirements at our integrated seamless pipe mill, purchases in the local market and by a 35 
megawatts power generating plant located within the Campana facility. 
We are currently building a second wind farm in Argentina at a cost of approximately $214 million, which 
would supply a further 30% of the current energy requirements of the facilities in Campana. This investment 
is expected to be completed during 2025.

North America 
Sales to customers in North America accounted for 46% of our sales of tubular products and services in 
2024, compared to 53% in 2023 and 61% in 2022. 
We have significant sales and production facilities in each of the United States, Canada and Mexico, where 
we provide customers with an integrated product and service offering based on local production capabilities 
supported by our global industrial system. In the past few years, we have extended our integrated product 
and service model, which we call Rig Direct®, throughout North America, and we operate a seamless pipe 
mill at Bay City, Texas, which is strategically located to serve the Eagle Ford and Permian regions. On January 
2, 2020, we acquired IPSCO, a U.S. seamless and welded pipe producer, and, in September 2023, we 
acquired Republic Tube’s OCTG pipe processing facility in Houston with heat treatment and threading 
operations, further strengthening our local production capabilities and capacity to provide Rig Direct® services 
in the United States. Under Rig Direct®, we manage the whole supply chain from the mill to the rig for 
customers under long-term agreements, integrating mill production with customer drilling programs, 
reducing overall inventory levels, simplifying operational and administrative processes, and providing technical 
and digital services. We first introduced the Rig Direct® model to Pemex in Mexico in 1994, and since then 
we have supplied them with pipes on a just-in-time basis. 
Today, we supply a large majority of our U.S. and Canadian customers for OCTG products with Rig Direct® 
services.  
 

Annual Report 2024

Sales to our oil and gas customers in the United States and Canada are highly sensitive to oil prices and 
regional natural gas prices. Over the past fifteen years, the drilling of productive shale gas and tight oil 
reserves, made possible by new drilling technology, has transformed drilling activity and oil and gas 
production in the United States and Canada. The United States has gone from being the largest global 
importer of oil to the largest global producer of crude oil and LNG. U.S. crude oil production has increased 
from 5.6 million b/d in 2011 to 13.2 million b/d in 2024 and has been the largest contributor to meeting 
growth in global oil demand during this period as well as making the United States a net exporter. This rapid 
increase in production, however, has contributed, at times, to an excess of supply in the global oil market and 
consequent fall in the price of oil. In 2020, the impact of the COVID-19 pandemic led to a sudden and 
substantial reduction in global oil demand in the first half of 2020 and a collapse in oil prices. Global oil 
demand and prices have now effectively recovered, along with economic activity, and OPEC and other 
producer countries, including Russia, implemented production cuts to lower supply below demand and 
reduce inventory levels. At the same time, U.S. shale producers have restrained investments in response to 
the post COVID-19 recovery of oil prices to accommodate financial market pressures to increase returns to 
shareholders and limit investments in production growth. 
Similarly, U.S. natural gas production has risen rapidly over the past decade and the United States became a 
net exporter of natural gas for the first time in 2017 and since 2023 has been the largest exporter of LNG to 
global markets. In Canada, there has been a similar shift towards drilling of shale gas and tight oil reserves. 
The drop in oil prices with the onset of the COVID-19 pandemic in the first half of 2020 resulted in a collapse 
in U.S. drilling activity, with the number of active rigs falling to the lowest level recorded in over 40 years. 
Crude oil production also fell back to 11.3 million b/d in each of 2020 and 2021, from 12.3 million b/d in 
2019. However, since then, there was a recovery in U.S. drilling activity through 2021 and 2022 before 
drilling activity began to decline moderately in the second half of 2023 reflecting lower oil prices compared to 
the levels reached in 2022, before stabilizing in the second half of 2024. North American natural gas prices 
also declined during the second half of 2023, due to increasing production, a low level of demand in the 
winter heating season and capacity limits on LNG exports, but, early in 2025, began to show signs of 
recovery on a tighter supply and demand balance. 
The level of drilling activity in North America, and consequently demand for our products and services, could 
also be affected by actions taken by the governments of the region to accelerate the energy transition by 
reducing demand for oil and gas and restricting drilling activity. 
During 2020, demand for, and sales of, our OCTG products in the United States and Canada collapsed along 
with drilling activity. As a result, we closed down many of our facilities in the United States and, we 
dismantled our Prudential welded pipe mill in Calgary, Canada, and integrated welded pipe production at our 
seamless pipe mill in Sault Ste. Marie, Ontario. Towards the end of 2020, demand for and sales of OCTG in 
the United States and Canada began a recovery which continued throughout 2021 and 2022 and the first 
part of 2023. During this recovery period we reopened many of the facilities we had shut down in 2020 and 
brought production at our Bay City mill to full capacity. A particular feature of this recovery was the 
exceptional price levels for hot rolled coil in the North American market which made the production of 
welded pipes uneconomic throughout 2021 and delayed the restart of U.S. welded pipe production into 
2022. The ramp up of production capacity in the United States was further affected by difficulties in hiring a 
qualified workforce in the post-COVID economy. In 2024, with the slowdown in drilling activity, demand and 
consumption of OCTG products declined, although average OCTG consumption per rig has increased along 
with drilling efficiencies. 
During 2018, the U.S. government introduced, under Section 232, tariffs and quotas on the imports of steel 
products, including steel pipes, with the objective of strengthening domestic production capacity utilization 
and investment. The proportion of the OCTG market supplied by imports initially declined from around 60% 
prior to the imposition of tariffs and quotas to around 40% at the end of 2018. OCTG imports subsequently 
rose to around 50% during the recovery from the pandemic when U.S. production was constrained but has 
fallen below 35% during the second half of 2024 as distributors reacted to a rise in inventory levels by 
cutting back on OCTG import purchases. Early in 2025, the U.S. government imposed a 25% tariff on 
virtually all imports of steel and steel derivatives, revoking previously negotiated country-specific exemptions 
and quota arrangements. As a result, all previously exempted or quota-managed countries became subject to 
the full 25% tariff on their steel exports to the United States. In addition, on February 1, 2025, the U.S. 
government announced the imposition, through the IEEPA, of across-the-board tariffs applicable to all 
products imported from Mexico, Canada and China (with the exception, as of the date of this annual report, 
of Mexican and Canadian products that comply with USMCA preferential rules of origin). These tariffs could 

Annual Report 2024 
50 
apply to certain products that Tenaris and other companies are currently importing under previously granted 
exclusions or tariff-free quotas.  
On October 27, 2021, the DOC initiated antidumping duty investigations on OCTG imports from Argentina, 
Mexico, and Russia and countervailing duty investigations of OCTG from Russia and South Korea. On October 
27, 2022, the ITC determined that the imports under investigation caused injury to the U.S. OCTG industry. 
Tenaris and other parties have appealed the agency determinations from the investigation to the Court of 
International Trade. In addition, in response to a request from the Government of Argentina, the WTO 
established a panel of experts to consider whether the DOC’s antidumping order applicable to Argentina is 
consistent with the international obligations of the United States. As a result of the investigation, and unless 
overturned on appeal, Tenaris is required to pay antidumping duties (at a rate of 78.30% for imports 
from Argentina and 44.93% for imports from Mexico) while the order is in effect. Tenaris has been paying 
antidumping duty deposits since May 11, 2022, reflecting the amount of such deposits in its costs. The 
deposit rates may be reset periodically based on the results of the administrative review process. In the first 
administrative review covering the period from May 11, 2022 to 31 October 2023, the DOC issued 
preliminary determinations in December, finding a margin of 6.8% for Siderca and 30.38% for Tamsa. The 
final determination, which could be different from the preliminary determination, is expected by September 
2025. As a result of the periodic review process, the deposits paid may be either returned to Tenaris, in whole 
or in part, or may be increased. 
Our sales in the United States are also affected by the level of investment of oil and gas companies in 
exploration and production in offshore projects. 
Oil and gas drilling in Canada is subject to strong seasonality, with the peak drilling season in Western 
Canada being during the winter months when the ground is frozen. During the spring, as the ice melts, 
drilling activity is restricted by the difficulty of moving equipment in muddy terrain. 
On June 30, 2021, Canada initiated an antidumping investigation on OCTG from Mexico. A full investigation 
was conducted and on January 26, 2022, the Canadian International Trade Tribunal found that Mexican 
imports were not injuring the Canadian OCTG industry and closed the inquiry without imposing any duties. 
In Mexico, we have enjoyed a long and mutually beneficial relationship with Pemex, the Mexican state-owned 
oil company, and one of the world’s largest crude oil and condensate producers. In 1994, we began 
supplying Pemex with Rig Direct® services. At the end of 2022, we renewed our long-term agreement with 
Pemex for an additional three-year period. 
In the last few years, the Mexican government has introduced measures that increase the role of state-owned 
enterprises, particularly CFE and Pemex, in oil production and processing activity and electricity dispatch, 
giving them priority over private companies. Pemex has been charged with reversing production declines and 
has built a new refinery, but over the past year its financial situation has deteriorated and, in response, has 
reduced investments and delayed payments to suppliers, including Tenaris, with the result that oil production 
in Mexico is falling rapidly. For more information on our credit exposure to Pemex, see “Risk Factors - Risks 
Relating to Our Business and Industry - Adverse economic or political conditions in the countries where we 
operate or sell our products and services may decrease our sales or disrupt our manufacturing operations, 
thereby adversely affecting our revenues, profitability and financial condition”. 
Drilling activity in Mexico and demand for our OCTG products dropped only slightly in 2020 as the country 
was protected from lower oil prices by a price hedging program. Following the pandemic, it increased 
moderately in 2022, was stable in 2023, but has collapsed in the second half of 2024, as Pemex reduced 
investments and supplier payments. 
South America 
Sales to customers in South America accounted for 19% of our sales of tubular products and services in 
2024, compared to 22% in 2023 and 20% in 2022.  
 

Annual Report 2024 
51 
Our largest market in South America is Argentina. We also have significant sales in Brazil, Guyana and 
Colombia. We have manufacturing subsidiaries in Argentina, Brazil, Colombia and Ecuador, while in Guyana, 
we provide in-country services.  
Our sales in South America are sensitive to the international price of oil and its impact on the drilling activity 
of participants in the oil and gas sectors, as well as to general economic conditions in these countries. In 
addition, sales in Argentina, as well as export sales from our manufacturing facilities in Argentina, are 
affected by governmental actions and policies, such as the taxation of oil and gas exports, measures affecting 
gas and gasoline prices in the domestic market and other matters affecting the investment climate. Sales in 
Brazil are also affected by governmental actions and policies and their consequences, such as measures 
relating to the taxation and ownership of oil and gas production activities and the operations of Petrobras. 
For more information, please see “Risk Factors - Risks Relating to Our Business and Industry - Adverse 
economic or political conditions in the countries where we operate or sell our products and services may 
decrease our sales or disrupt our manufacturing operations, thereby adversely affecting our revenues, 
profitability and financial condition”. 
A principal component of our marketing strategy in South American markets is the establishment of long-
term supply agreements and Rig Direct® services with national and international oil and gas companies 
operating in those markets. 
In Argentina, we have a significant share of the market for OCTG products. We have longstanding business 
relationships with YPF S.A. (“YPF”), the Argentine state-controlled company, and with other operators in the 
oil and gas sector. We strengthened our relationship with YPF in 2013 through a long-term agreement, 
which was renewed for an additional five-year term at the beginning of 2022, under which we provide Rig 
Direct® services with the objective of reducing YPF’s operational costs as it aims to increase production 
through investments in Argentina’s shale oil and gas reserves. In 2020, our sales were affected by ongoing 
uncertainties regarding the energy policies that would be adopted by a new government as well as the onset 
of the COVID-19 pandemic. Activity has since recovered and is expected to increase further as pipeline 
infrastructure is developed for transporting oil and gas from the prolific Vaca Muerta shale play to 
international markets. The country’s energy trade balance, which used to show a large deficit, is now starting 
to show a surplus as pipeline capacity has been developed to transport natural gas from Vaca Muerta to the 
main consuming regions of the country and to export oil. Further pipeline infrastructure, and possible LNG 
exporting infrastructure, is expected over the next years. We reactivated our welded pipe mill in Valentin 
Alsina, province of Buenos Aires, to supply pipes for the pipelines already constructed and under construction 
and these are supplemented by deliveries from our mill in Brazil. 
In Brazil, we have a longstanding business relationship with Petrobras. We supply Petrobras with casing and 
tubing (including premium connections) and line pipe products, many of which are produced in our Brazilian 
welded pipe facility, for both offshore and onshore applications. More recently, we have increased the sale of 
imported seamless products to Petrobras for offshore use, including the supply of seamless casing with 
premium connections, accessories and Rig Direct® services for use in the pre-salt area and seamless line pipe 
for use in offshore risers. In 2020, with the onset of the COVID-19 pandemic and the collapse in oil prices, 
Petrobras reduced its onshore drilling operations to focus on pre-salt offshore developments. In 2022 and 
2023, offshore drilling activity increased as a result of the development of the Buzios and other pre-salt fields 
by Petrobras as well as other investments by major oil companies. Consumption of OCTG products in Brazil, 
doubled in 2023 and remained at a similar level in 2024. Demand for line pipe for pipeline projects, which 
has been at a very low level for some years, picked up in 2024 as a major offshore pipeline is being installed, 
while demand for offshore risers and flowlines has also increased. In response to market-opening measures 
and the attractiveness of the deepwater reserves, major oil companies have been investing in Brazil, while 
Petrobras has focused investments in world class assets in deepwater. 
In Guyana and neighboring Suriname, offshore drilling activity has increased over the past few years 
following the discovery of large, cost competitive oil reserves. We are supplying casing for many of the 
exploration wells and, at the end of 2021, we were awarded a 10-year contract to supply large and medium 
diameter casing with Rig Direct®-alike services to the main deepwater offshore development projects in the 
Stabroek block. In 2024, we were also awarded the line pipe and insulation coating for a deepwater 
development in Suriname and the insulation coating for an offshore pipeline in Guyana. These developments 
are transforming the Guyana and Suriname economies and are yielding a significant new source of oil to 
global markets.

In Colombia, we have established a leading position in the market for OCTG products since 2006, following 
our acquisition of TuboCaribe, a welded pipe manufacturing facility located in Cartagena. The market grew 
in the previous decade as the country encouraged investment in its hydrocarbon industry and opened its 
national oil company to private investment. In 2020, the pandemic-related collapse in oil prices resulted in a 
drop of drilling activity which recovered in 2021 and 2022. In 2023 and 2024, however, drilling activity has 
been affected by government policies aimed at reducing exploration activity while local protests and security 
concerns have increased at many drilling locations. Our principal customer in Colombia is Ecopetrol S.A. 
(“Ecopetrol”), to which we supply Rig Direct® services. In February 2025 we renewed our agreement with 
Ecopetrol for two years. 
We also have sales in Ecuador, supplying Petroamazonas Ecuador S.A., which merged with EP PetroEcuador, 
the national oil company, as well as private operators. To increase local content, we have established a local 
OCTG threading facility in Machachi. 
We were present in the Venezuelan OCTG market for many years and we maintained business relationships 
with Petróleos de Venezuela S.A. and the joint venture operators in the oil and gas sector until the imposition 
of economic sanctions by the Office of Foreign Assets Control (“OFAC”). Additionally, we maintained 
business relationships with Chevron in Venezuela until April 22, 2020, when their sanctions license expired. In 
2023, Chevron was authorized to resume certain operations, which led to a limited resumption of sales in 
Venezuela but, on March 1, 2025, the US government decided not to renew the Chevron sanctions license. 
Europe 
Sales to customers in Europe accounted for 10% of our sales of tubular products and services in 2024, 
compared to 7% in 2023 and 8% in 2022. 
Our single largest country market in Europe has traditionally been Italy. The market for steel pipes in Italy (as 
in much of the EU) is affected by general industrial production trends, especially in the mechanical and 
automotive industry, and by investment in power generation, petrochemical and oil refining facilities. In the 
past three years, demand for seamless pipes in these segments in Europe has declined reflecting the increase 
in energy prices following the Russian invasion of Ukraine and the prolonged decline in industrial production. 
In 2022, although activity was affected by the Russian invasion, our sales increased as prices rose to 
compensate higher costs, while in 2023, although activity declined, our sales remained stable reflecting a 
change in the competitive environment. In 2024, however, our sales declined reflecting lower activity and 
competitive pressures from low-cost imports from China and Ukraine. 
In Europe, we also have significant sales to the oil and gas sector, particularly in the North Sea, but also in 
other areas like Romania and Turkey. Demand from this market is affected by oil and gas prices in the 
international markets and their consequent impact on oil and gas drilling activities. In 2022, we ceased sales 
to Russia that would breach applicable sanctions imposed by the U.S., and the EU following the Russian 
invasion of Ukraine. Sales in the North Sea rose during 2023 and remained stable in 2024 as drilling and gas 
pipeline construction activity increased, but are expected to decline in 2025 as activity, particularly in the UK, 
is curtailed. 
In 2024, Turkey was our largest country market in Europe, reflecting increased oil and gas activity and 
infrastructure development in the country. We supplied an offshore pipeline for a natural gas development in 
the Black Sea as well as premium OCTG used for onshore drilling and pipes for a gas storage project. 
Europe is also a region which we expect will be at the forefront of developments in low-carbon energy, 
including hydrogen storage and transportation, CCS, geothermal and waste-to-energy power generation. We 
are participating in these market segments where we expect to see growth in the coming years. 
Asia Pacific, Middle East and Africa 
Sales to customers in the Asia Pacific, Middle East and Africa accounted for 26% of our sales of tubular 
products and services in 2024, compared to 18% in 2023 and 11% in 2022.

Our largest single country markets in the region are Saudi Arabia and the United Arab Emirates. In Saudi 
Arabia, in response to policies that have been implemented to diversify the economy and increase local 
manufacturing, we have developed a substantial local manufacturing presence, first through the 
establishment of local premium threading facilities, and, more recently, through the acquisition of controlling 
participations in two welded pipe producers. In January 2019, we acquired 47.8% of SSPC, a listed ERW steel 
pipe producer. With the acquisition of SSPC, we also acquired a 35% share interest in GPC, a Saudi-German 
joint venture, established in 2010 and located in Jubail, Saudi Arabia, which manufactures LSAW pipes. In 
May 2023, SSPC increased its participation in GPC to 57.3% when the German shareholder in GPC decided 
to exit. In 2022, we entered into a long-term agreement with Saudi Aramco for the supply of seamless OCTG 
products that prioritizes local production where possible. In 2023, we entered into a similar long-term 
agreement for LSAW OCTG products, while we also have medium-term supply agreements with Saudi 
Aramco for ERW OCTG and line pipe products. In 2024, we had a record year of sales in Saudi Arabia as, in 
addition to deliveries under these agreements, we made deliveries pursuant to a tender that was awarded to 
replenish stocks of premium OCTG as Saudi Aramco increased its gas drilling activity. 
In the United Arab Emirates, we inaugurated an industrial complex with a newly-constructed premium 
threading facility, dedicated training facilities and an expanded service yard in February 2024. This followed 
the award, in August 2019, of a long-term agreement with Rig Direct® conditions, valued at $1.9 billion, to 
supply approximately half of the OCTG requirements of Abu Dhabi National Oil Company (“ADNOC”) in Abu 
Dhabi over the following five to seven years. At the end of 2024, ADNOC confirmed an extension to cover 
the full seven years as it confirmed an increase in drilling activity for 2025. 
We have a wide-ranging presence in the rest of the region, with industrial facilities in Indonesia, China, 
Kazakhstan and Nigeria and service centers in various additional countries. 
Our sales in this region remain sensitive to international prices of oil and gas and their impact on drilling 
activities as well as to the production policies pursued by OPEC, and, more recently, OPEC+ countries, many 
of whose members are located in this region. In the past few years, oil and gas producing countries in the 
Middle East, led by Saudi Arabia, have increased investments to develop gas reserves to fuel regional gas-
based industrial development, which have positively affected their consumption of premium OCTG products. 
Saudi Arabia, in particular, is pursuing strong growth in conventional and unconventional gas drilling activity. 
The main national oil companies in the Gulf have also increased investments to add oil and LNG production 
capacity as they seek to accelerate the monetization of their oil and gas reserves, although Saudi Arabia 
announced in 2024, that it would curtail its oil production capacity expansion plans. 
In North Africa, there have been significant discoveries and development of offshore gas reserves in the 
Mediterranean in recent years and international oil companies have made investments in the region. In sub-
Saharan Africa, after several years of limited investments, international oil companies began to gradually 
increase their investments in exploration and production in offshore projects from 2022. 
In the Caspian region, major oil companies operating in Kazakhstan and Azerbaijan increased their 
investments and drilling activity following a recovery of oil prices in 2017. In 2020 and 2021, however, our 
sales were affected by the impact of the COVID-19 pandemic on the operations of our customers and the 
impact on drilling activity of adherence to the production cuts agreed by the OPEC+ countries in response to 
the collapse of oil demand due to the pandemic. Since then, drilling activity and our sales have remained at 
low levels. 
In the past few years, uprisings affected drilling activity in countries such as Syria, Libya and Yemen. In 
addition, for a number of years, U.S. and EU sanctions have affected production and exports in Iran. 
In Indonesia and other markets in South East Asia and Oceania, drilling activity, particularly offshore drilling 
activity, is mainly affected by demand and prices for natural gas and LNG. The region is a major producer of 
natural gas and LNG particularly for the energy-hungry economies of China and North-East Asia. 
Our sales in China are concentrated on premium OCTG products used in oil and gas drilling activities. Over 
the past 15 years, Chinese imports of OCTG products have remained at a very low level as local producers 
compete ferociously in an oversupplied market. We continue, however, to seek new markets in niche 
applications and in 2016 we opened a components facility for processing pipes for use in airbags for 
automobiles, which we have twice expanded. In 2020, we established a joint venture with Baotou Steel, a 
major domestic supplier of seamless pipes to the onshore oil and gas fields, for the construction of a 
premium threading facility located within our partner’s steelmaking facilities in Inner Mongolia. The new 

Annual Report 2024 
54 
facility, which finishes pipes produced mainly by our joint venture partner, began production during the first 
quarter of 2022. Our participation in the joint venture is 60%. During 2022, Baotou Steel and Baosteel 
International Group (“Baosteel”) merged their seamless pipe businesses, but at the end of 2023, this merger 
was reversed, and we have resumed operations with our original joint venture partner. 
In Japan, our former subsidiary, NKKTubes, competed against other domestic producers. In November 2022 
we entered into a definitive wrap-up agreement with JFE to terminate our joint venture and cease NKKTubes’ 
operations. The market for steel pipe products in Japan is mostly industrial and depends on general factors 
affecting domestic investment, including production activity. With the closure of manufacturing and 
production operations of NKKTubes in June 2022, we have largely ceased to serve this market. 
Our sales in the greater region could be adversely affected by political and other events in the region, such as 
armed conflicts, terrorist attacks and social unrest, which could materially impact the operations of 
companies active in the region’s oil and gas industry. Our sales in the region can also be affected by the levels 
of inventories held by the principal national oil companies and their effect on purchasing requirements. For 
more information, please see “Risk Factors - Risks Relating to Our Business and Industry - Adverse economic 
or political conditions in the countries where we operate or sell our products and services may decrease our 
sales or disrupt our manufacturing operations, thereby adversely affecting our revenues, profitability and 
financial condition”. 
Sales in the region declined to a low level in 2021 as a result of various factors, including the slowdown in 
investments in drilling activity as a result of the pandemic and reduction in oil demand and prices and 
ongoing inventory reductions at some of the region’s largest consumers such as Saudi Arabia and the United 
Arab Emirates. In 2022, our sales in the region began to recover while, in 2023, our sales benefited from a 
strong recovery in activity and inventory shortages. Our sales increased further in 2024 led by Saudi Arabia 
following a tender award to help Saudi Aramco to replenish inventory levels. 
Others 
Our other products and services include sucker rods used in oil extraction activities, oil and gas services, 
namely fracking and coiled tubing services in Argentina, sales of pipe for plumbing applications from our 
Italian Piombino mill, coiled tubes used in oil and gas extraction activities, and sales of raw materials and 
energy that exceed our internal requirements. 
On November 30, 2023, we acquired the pipe coating business of Mattr, which has nine pipe coating 
facilities and two R&D centers around the world, and is a global leader in anti-corrosion and insulation 
coating for offshore pipelines. The acquired plants are complementary to our coating plants in Argentina, 
Brazil, the United States, Italy, Nigeria and Saudi Arabia. Although we reported the sales of the newly 
acquired in the “Others” segment for the remainder of 2023, as we advanced with the integration of the 
business with our Tubes operations, we began reporting these results within our Tubes operating segment. 
Net sales of other products and services amounted to 5% of total net sales in 2024, compared to 5% in 
2023 and 5% in 2022. 
During 2022, we closed down our Brazilian industrial equipment business.

Competition 
The global market for steel pipe products is highly competitive. Seamless steel pipe products, which are used 
extensively in the energy industry particularly for offshore, high pressure, high stress, corrosive and other 
complex applications, are produced in specialized mills using round steel billets and specially produced ingots. 
Welded steel pipe products are produced in mills which process steel coils and plates into steel pipes. Steel 
companies that manufacture steel coils and other steel products but do not operate specialized seamless steel 
mills are generally not competitors in the market for seamless steel pipe products, although they often 
produce welded steel pipes or sell steel coils and plates used to produce welded steel pipes. 
The production of steel pipe products following the stringent requirements of major oil and gas companies 
operating in offshore and other complex operations requires the development of specific skills and significant 
investments in manufacturing facilities. By contrast, steel pipe products for standard applications can be 
produced in most seamless pipe mills worldwide and sometimes compete with welded pipe products for such 
applications including OCTG applications. Welded pipe, however, is not generally considered a satisfactory 
substitute for seamless steel pipe in high-pressure or high-stress applications. 
Over the past two decades, substantial investments have been made, especially in China but also in other 
regions around the world, to increase production capacity of seamless steel pipe products. Production 
capacity for more specialized product grades has also increased. With the downturn between 2014 and 2016 
in the price of oil and demand for tubes for oil and gas drilling, the overcapacity in steel pipe and seamless 
steel pipe production worldwide became acute, extending beyond commodity grades. This situation has been 
accentuated by the prospect of limited demand growth in an energy transition. Effective competitive 
differentiation and industry capacity closures will be key factors for Tenaris. 
Our principal competitors in steel pipe markets worldwide are described below. 
• 
Vallourec S.A. (“Vallourec”), a French company, has mills in Brazil, China, and the United States. 
Vallourec has a strong presence in the U.S. and Brazilian markets for OCTG and line pipe products and 
the Brazilian market for industrial products, as well as a significant market share in the international 
market with customers primarily in the Middle East, Africa and Asia Pacific. Vallourec is an important 
competitor in the international OCTG market, particularly for high-value premium joint products. Prior 
to the 2014-16 downturn in oil prices, Vallourec increased its production capacity by building mills in 
Brazil (jointly with Nippon Steel Corporation “NSC”) and Youngstown, Ohio, acquiring tubular 
businesses in the United States and Saudi Arabia, and acquiring a Chinese seamless steel producer. 
Since then, Vallourec has carried out two major financial restructuring processes and has emerged as a 
financially stable company with a reduced industrial perimeter under new management and owners. In 
the second financial restructuring, Vallourec’s creditors, including Apollo, a private equity house, 
assumed effective control. Under the same restructuring, Vallourec closed its German mills during 
2023 and invested EUR100 million in its Brazilian mills to enable the transfer of its specialized products 
for oil and gas customers from Germany to Brazil. In 2024, ArcelorMittal S.A. (“ArcelorMittal”) 
acquired Apollo’s entire shareholding (28.4% of voting rights and 27.5% of the share capital) and 
became its reference shareholder. 
 
• 
U.S. Steel Corporation (“U.S. Steel”), a large U.S. steel manufacturer, has long been a significant 
player in the U.S. market for seamless OCTG and line pipe. During the pandemic-induced downturn, it 
closed its large diameter seamless pipe mill in Lorain and the welded pipe facilities it acquired from 
Lone Star in 2008 to focus its pipe business on its medium range seamless pipe mill in Fairfield, 
Alabama where it also constructed an EAF steel mill to have a fully integrated facility. In December 
2023, U.S. Steel and NSC announced that they had entered into a definitive agreement pursuant to 
which NSC will acquire U.S. Steel, but have been unable to complete the transaction due to regulatory 
decisions. 
 
• 
Japanese companies NSC and, to a lesser extent, JFE together enjoy a significant share of the 
international market, having established strong positions in markets in the Far East and the Middle 
East. They are internationally recognized for their supply of high-alloy grade pipe products. Over the 
previous decade, NSC had increased its capacity to serve international markets through the 
construction with Vallourec of a new seamless pipe mill in Brazil, and further strengthened its ties with 
Vallourec through participating in Vallourec’s 2016 capital increase and combining their respective 
Brazilian operations. As part of the latest financial restructuring of Vallourec, NSC relinquished its 
participation in the Brazilian operation and ceded its reference shareholder position in Vallourec. In 

Annual Report 2024 
56 
2022, NSC, as part of a general restructuring of its steelmaking operations, closed one of its three 
seamless pipe production mills and announced the closure of its large diameter welded pipe mill and 
its exit from the large diameter welded line pipe market. 
 
• 
Over the past two decades, TMK, a Russian company, led the consolidation of the Russian steel pipe 
industry, invested to modernize and expand its production capacity in Russia and expanded 
internationally through acquisitions into Eastern Europe and the United States. TMK also expanded in 
the Middle East through the acquisition of a controlling interest in Gulf International Pipe Industry LLC, 
a welded pipe producer in Oman. More recently, however, TMK adopted a strategy of monetizing its 
international assets by reducing its participation in Gulf International Pipe and selling IPSCO to Tenaris, 
as well as strengthening its position in its domestic market by acquiring Chelpipe, the second Russian 
producer of seamless pipes in 2021. In 2022, following the Russian invasion of Ukraine, the API 
withdrew its license for products produced in TMK’s mills in Russia. Russian producers or their 
controlling shareholders are now subject to U.S., EU and UK sanctions, among others, and are now 
largely prevented from competing in several markets. 
 
• 
In the Middle East, particularly in Saudi Arabia, which has implemented policies to encourage local 
production for its oil and gas industry, several pipe mills were established, including a seamless pipe 
mill built by Jubail Energy Services Company (“JESCO”), a company established with majority 
participation from a state-backed industrial development company, and a seamless pipe mill originally 
built by a joint venture of ArcelorMittal and local shareholders (“AMTJ”). These local players have been 
strengthening their capabilities and, between them, have taken a leading share of the pipes supplied 
to Saudi Aramco as well as exporting to other countries in the Middle East and the rest of the world. In 
2021, JESCO and AMTJ, who were both operating with losses, combined their operations at the 
behest of the Saudi Public Investment Fund. 
 
• 
Over the past two decades, Chinese producers increased production capacity substantially and strongly 
increased their exports of steel pipe products around the world. Due to unfair trading practices, many 
countries, including the United States, the EU, Canada, Mexico and Colombia, have imposed anti-
dumping restrictions on Chinese imports to those regions. In 2009, the largest Chinese producer of 
seamless steel pipes, Tianjin Pipe (Group) Corporation Limited (“TPCO”), announced a plan to build a 
new seamless pipe facility in the United States in Corpus Christi, Texas; heat treatment and pipe 
finishing facilities were constructed but steelmaking and hot rolling facilities have not been completed. 
As part of a financial restructuring, a 51% shareholding in TPCO was sold to Shanghai Electric Group 
and has now been sold on to Citic Group Corporation Ltd. (“Citic”), a state-owned conglomerate. 
Although producers from China compete primarily in the “commodity” sector of the market, several 
of these producers, including Baosteel, Hengyang and TPCO, have developed and are selling more 
sophisticated products, particularly in the domestic market. 
 
• 
Although the tubes and pipes business in the United States and Canada has experienced significant 
consolidation over the years, many new players have built pipe mills in the United States. These 
include, in addition to TPCO, Boomerang LLC, a company formed by a former Maverick executive that 
opened a welded pipe mill in Liberty, Texas, now known as PTC Liberty Tubulars and part of the PTC 
Alliance; Benteler A.G. (“Benteler”), a European seamless pipe producer that built a new seamless pipe 
mill in Louisiana, which opened in September 2015; and a plethora of welded pipe mills established by 
subsidiaries of foreign pipe producers, such as SeAH Steel (“SeAH”), of Korea and JSW Group 
(“JSW”), of India. North American pipe producers, including US Steel, are largely focused on supplying 
the U.S. and Canadian markets, where they have their production facilities. 
 
• 
Korean welded pipe producers, who have a limited domestic market, have targeted the U.S. market 
for standard applications. They have gained a significant market position, despite the application of 
anti-dumping duties for unfair trading practices and being subject to Section 232 quotas. One of 
them, SeAH, has acquired and built local welded pipe production facilities in the United States. 
 
• 
Benteler, Tubos Reunidos S.A. of Spain (“Tubos Reunidos”), and Voest Alpine A.G. of Austria (“Voest 
Alpine”) each have a significant presence in the European market for seamless steel pipes for industrial 
applications. Voest Alpine also has a relevant presence in the U.S. and Canadian OCTG markets and 

Annual Report 2024 
57 
some other international OCTG markets. In 2016, Tubos Reunidos opened an OCTG threading facility 
targeting international markets, including the United States. 
 
• 
ArcelorMittal has seamless pipe mills in Romania and South Africa as well as a 33.3% participation as 
technical partner in AMTPJ in Saudi Arabia. It also has a number of welded pipe mills in North America 
and Europe, supplying the industrial and automotive sectors. In 2024, ArcelorMittal acquired 28.4% of 
the voting rights (representing a 27.5% of the share capital) in Vallourec, becoming its reference 
shareholder. 
 
Producers of steel pipe products can maintain strong competitive positions in markets where they have their 
pipe manufacturing facilities due to logistical and other advantages that permit them to offer value-added 
services and maintain strong relationships with domestic customers, particularly in the oil and gas sectors. We 
have established strong ties with major consumers of steel pipe products in the home markets of our 
manufacturing subsidiaries, reinforced by Rig Direct® services, as discussed above.

Raw Materials and Energy  
The majority of our seamless steel pipe products are manufactured in integrated steelmaking operations 
using the electric arc furnace route, with the principal raw materials being steel scrap, DRI, HBI, pig iron and 
ferroalloys. In Argentina we produce our own DRI from iron ore using natural gas as a reductant. Our 
integrated steelmaking operations consume significant quantities of electric energy, purchased from the local 
electricity markets, provided from our own renewable wind farm and other renewable sources, and from 
thermal-electric power production. Our welded steel pipe products are processed from purchased steel coils 
and plates. 
The weight of the different steelmaking raw materials and steel vary with the proportion of seamless and 
welded pipes in the total production mix and among the different production facilities in our industrial 
system, as well as the specifications of the final products and other factors. On average, in 2024, steel scrap, 
pig iron, HBI and DRI represented approximately 22% of our steel pipe products’ costs, while purchased steel 
in the form of billets, coils or plates represented approximately 15%, with direct energy accounting for 
approximately 3%. 
The above raw material inputs are subject to price volatility caused by supply, political and economic 
situations, financial variables and other unpredictable factors. For further information on price volatility, see 
“Risk Factors – Risks Relating to Our Business and Industry – Increases in the cost of raw materials, energy 
and other costs, limitations or disruptions to the supply of raw materials and energy, and price mismatches 
between raw materials and our products may hurt our profitability”. The costs of steelmaking raw materials 
and of steel coils and plates were subject to high levels of volatility during 2022 as they were affected by the 
Russian-Ukraine armed conflict, and the sanctions being imposed on Russian individuals, companies and 
institutions. They returned to more stable levels in 2023 and declined in 2024. For more information, see 
“Risk Factors - Risks Relating to Our Business and Industry - Armed conflicts, such as the Russia-Ukraine war, 
may adversely affect our operations”. 
Steel scrap, pig iron and HBI 
Steel scrap, pig iron and HBI for our steelmaking operations are sourced from local, regional and international 
suppliers. In Argentina we produce our own DRI and source ferrous scrap domestically through a wholly 
owned scrap collecting and processing subsidiary. In Italy we purchase pig iron and ferrous scrap from local 
and regional markets. In Mexico we import our pig iron and HBI requirements and purchase scrap from 
domestic and international markets. In Romania we source ferrous scrap from the domestic market and we 
import pig iron. In the United States, we source scrap from the local market to supply our steelmaking facility, 
and purchase pig iron from international markets. 
International prices for steel scrap, pig iron and HBI can vary substantially in accordance with supply and 
demand conditions. 
Annual scrap prices decreased in 2024. As a reference, prices for the U.S. East Coast Shredded Scrap, 
published by Platts, averaged $375 per ton in 2024 and $391 per ton in 2023, while they averaged $428 per 
ton in 2022. Steel scrap prices declined to a two-year low, pressured by an oversupply of low-cost Chinese 
rebar in the steel market, which has affected scrap purchases from Turkey, a major consumer of steel scrap 
exports. 
Decarbonization efforts, as well as increasing production of steel in electric arc furnaces, have been 
supporting prices and are likely to put upwards pressure on prices going forward as availability of high-quality 
scrap becomes increasingly scarce in relation to demand. 
In 2024, Brazil and Ukraine remained the largest pig iron suppliers to the American and European markets 
because of the significant decrease in supply from Russia. In 2024, the global pig iron market experienced a 
1.3% decrease in production compared to 2023. This decrease is attributed also to decarbonization efforts 
which are resulting in lower demand for pig iron. Prices showed a downward tendency during 2024, 
reaching levels of around $440 per ton in early 2025. 
International prices for steel scrap, pig iron and HBI can vary substantially in accordance with supply and 
demand conditions. 
 

Annual Report 2024

Iron ore 
We consume iron ore in the form of pellets for production of DRI in Argentina. Siderca’s consumption of iron 
ore during 2024 was approximately 958 thousand tons, supplied by Vale International S.A. and Samarco 
Mineração S.A. from Brazil, and Iron Ore Company (“IOC”) from Canada. Annual iron ore prices remained at 
low levels during 2024 in comparison to 2023, falling in October to the lowest level in two years. As a 
reference, prices for IODEX 62% Fe Index, published by Platts, averaged $109 per ton in 2024, in comparison 
to $120 per ton in 2023 and $120 per ton in 2022. After reaching $143 per ton in January 2024, iron ore 
prices fell to $89 per ton in September 2024, followed by a slight recovery to $105 per ton in February 2025. 
Pellet premiums’ prices averaged $40 per ton in 2024, and $45 per ton in 2023, while they averaged $72 per 
ton in 2022. The DR pellet market had a price decrease in 2023 as demand from Europe and Middle East and 
Africa remained weak throughout the year. At the end of 2023, prices had a seasonal increase, followed by a 
downturn in prices in January 2024, which was sustained during the whole year, due to weak steel market 
worldwide and tight margins. During 2024, Chinese steel exports reached record levels, with more 
competitive prices than other regions, resulting in an oversupply in the global market. This situation put 
pressure on steel prices, as well as on steelmaking raw materials. 
Ferroalloys 
The purchase of ferroalloys is coordinated globally to ensure supply for each of our steel shops. International 
prices of ferroalloys can vary substantially within a short period of time. 
In 2023, demand for ferroalloys was weak to the point some materials traded beneath the production costs 
of many producers, forcing them to curtail production mainly in Europe and India. Lower material availability 
and rising production costs, such as electricity, supported a rebound in ferroalloys’ prices from September 
levels to the end of the year. 
In the first half of 2024, manganese alloys saw a sharp price increase, driven by the prolonged suspension of 
a major mine in Australia. However, in the second half, weak market demand offset the lack of supply. 
Molybdenum prices remained strong and stable throughout 2024, driven by robust demand from the oil and 
gas and defense industries, along with rising production in China and Peru. 
Round steel bars 
We mainly satisfy our steel bars and ingots requirements with materials produced in our steelmaking facilities 
in Argentina, Italy, Mexico, Romania and the United States. We complement this internal supply with limited 
purchases of steel bars and ingots from third parties as required, particularly for use in our seamless steel pipe 
facilities in the United States. 
In Canada, we mainly source our steel bars requirements from our integrated facilities in Argentina, Italy, 
Mexico, Romania and United States.  
In the United States, we own a steel shop facility in Koppel, Pennsylvania. After having completed certain 
investments in 2021, this facility provides a significant portion of the steel bars required by our Bay City and 
Ambridge mills. We also use steel bars imported from our integrated facilities in Romania, Italy, Argentina 
and Mexico. These imports have been excluded from Section 232 tariffs, by application of certain commercial 
agreements (between the U.S. and the EU, and between the U.S. and Mexico), but, under the reset of these 
Section 232 tariffs made by the new U.S. administration, tariffs on these imports are being applied since 
March 12, 2025. Additionally, we have contracts in place with Nucor Steel and U.S. Steel to purchase a 
portion of the steel bar requirements in our Bay City mill. 
 
In Japan, following the termination of our joint venture and the closure of the NKKTubes plant, JFE agreed to 
provide us with 13 Chrome alloy products for a two-year period, that was extended for an additional five 
year period, while we advance with the investments required to produce such materials in the rest of our 
industrial system.

Steel coils and plates 
For the production of welded steel pipe products, we purchase steel coils and steel plates principally from 
domestic producers for processing into welded steel pipes. We have welded pipe operations in Argentina, 
Brazil, Canada, Colombia, Saudi Arabia and the United States. 
Steel coil market prices in 2024 decreased 14%. As a reference, prices for hot rolled coils, HRC Midwest USA 
Mill, published by CRU, averaged $850 per metric ton in 2024, $991 per metric ton in 2023, in comparison 
with $1,128 per metric ton in 2022. 
 
For our welded pipe operations in the United States, a significant part of our requirements for steel coils are 
supplied by Nucor Steel which is our principal supplier in the United States. Nucor Steel has a steel coil 
manufacturing facility in Hickman, Arkansas, near to our principal welded pipe facility in the United States. 
During 2024, Nucor Steel supplied steel coils under a long-term purchase agreement, which is due to expire 
at the end of 2026. 
 
In Canada, we have restarted negotiations with the main local suppliers to reach long-term agreements for 
our welded pipe operations. Among such suppliers are ArcelorMittal Dofasco, which has steel coil 
manufacturing facilities in Hamilton, Ontario, and Algoma Steel, which has steel coil manufacturing facilities 
in Sault Ste. Marie, Ontario. 
 
We also purchase steel coils and plates for our welded pipe operations in South America (Colombia, Brazil 
and Argentina). In Brazil, principally from Gerdau S.A., ArcelorMittal Tubarão and Usiminas, a subsidiary of 
Ternium. In Argentina from Ternium Argentina S.A. (“Ternium Argentina”), a subsidiary of Ternium, and 
from Ternium’s facilities in Mexico. In addition, in Brazil we also source plates from international suppliers 
when not produced domestically.  
 
In Saudi Arabia, we mainly purchase steel coils from the local market for SSPC and plates from China for 
GPC. 
 
Energy 
We consume substantial quantities of electric energy, mainly at our electric steel shops in Argentina, Italy, 
Mexico, Romania and the United States. 
In Argentina, our local electric energy requirements are satisfied through supply from a 100MW wind farm, 
which was built with an investment of around $200 million and has been accounting for around 50% of the 
consumption of our main industrial facility in Campana since October 2023, purchases in the local market, 
and supply from a 35-megawatt thermo-electric power generating plant located within the Campana facility. 
In Dalmine, Italy, we have a 120-megawatt power generation facility which is designed to have sufficient 
capacity to meet most of the electric power requirements of the operations. The additional energy needed to 
cover the peaks of consumption is partially purchased through a power purchase agreement (“PPA”) with 
Axpo Italia started in November 2024 for 15 GWh/year of electricity produced from a solar plant. The residual 
energy required and the excess produced are purchased and sold to the market while heat is sold for district 
heating or used internally. In Mexico, our electric power requirements are mainly satisfied by Techgen, a 
natural gas-fired combined cycle electric power plant in the Pesquería area of the State of Nuevo León, while 
a small portion of our energy requirements are furnished by the Mexican government-owned CFE. In October 
2024 a new Energy constitutional reform was approved in which Mexico’s two largest energy state-owned 
companies, Pemex and CFE, have been reclassified as public state enterprises, emphasizing their role in 
serving the “public interest”. The reform also clearly states that private activities in the electricity industry will 
not take precedence over public enterprises. The potential impact on the energy supply and its cost related to 
this reform will not be known until the publication of the secondary regulation in the coming months. For 
more information, see “Risk Factors - Risks Relating to Our Business and Industry - Adverse economic or 
political conditions in the countries where we operate or sell our products and services may decrease our 
sales or disrupt our manufacturing operations, thereby adversely affecting our revenues, profitability and 
financial condition”. In Romania and the United States, we source electric energy from the local market. 

Annual Report 2024

We consume substantial volumes of natural gas in Argentina, for the generation of DRI in addition to the 
requirements for producing seamless pipes. Tecpetrol S.A. (“Tecpetrol”), a San Faustin subsidiary, is our main 
natural gas supplier in Argentina under market conditions and according to local regulations.  
We have transportation capacity agreements with Transportadora de Gas del Norte S.A. (“TGN”), a company 
in which San Faustin holds a significant but non-controlling interest, corresponding to capacity of 1,000,000 
cubic meters per day until April 2027. In order to meet our transportation requirements for natural gas above 
volumes contracted with TGN, we also have agreements with Naturgy S.A. (“Naturgy”), for a maximum 
transportation capacity corresponding to approximately 970,000 cubic meters per day. For the final 
transportation phase, we also have a supply contract with Naturgy. Both contracts with Naturgy are in place 
until April 2025 and are expected to be renewed. 
In addition to the amount of gas consumed at our Italian plants, we also require a substantial volume of 
natural gas to feed our power generation facility in Italy. Our natural gas requirements for the power 
generation facility are currently supplied by Edison Energia S.p.A while the natural gas consumed at our 
Italian plants is supplied by Eni S.p.A.  
 
Our costs for electric energy and natural gas vary from country to country. Prior to late 2021, energy costs 
remained generally flat due to the increasing availability of natural gas from shale plays and additional 
renewable energy generation at more competitive prices. In a context of uncertainty regarding future energy 
prices, in December 2020, the Argentine government launched a new gas plan to increase natural gas supply 
following a drop from the maximum levels reached in 2019. Because winter demand for natural gas has 
outpaced supply, Argentina has been required to import natural gas from Bolivia and Chile and LNG from the 
international market at high prices, in addition to using liquid fuel to generate electricity. In mid-2023, the 
Gasoducto Perito Francisco Pascasio Moreno was completed increasing the supply and improving costs 
through substantially lower use of LNG and/or liquid fuel. In late 2021, energy and gas prices increased, 
particularly in Europe. The Russian invasion of Ukraine led to renewed volatility in energy commodity prices, 
accelerated by the low level of inventories throughout the first half 2022, reaching a peak in late August and 
then slowly stabilizing at high levels. In early 2023, European electricity prices fell to pre-war levels, thanks to 
lower gas prices, mainly due to a particularly mild winter, and remained relatively stable throughout 2023 
and much of 2024. In late 2024 prices rose during the winter months as colder winter weather led to a rapid 
drawdown of gas in storage. See “Risk Factors – Risks Relating to Our Business and Industry – Increases in the 
cost of raw materials, energy and other costs, limitations or disruptions to the supply of raw materials and 
energy; and price mismatches between raw materials and our products may hurt our profitability”, “Risk 
Factors – Risks Relating to Our Business and Industry – Adverse economic or political conditions in the 
countries where we operate or sell our products and services may decrease our sales or disrupt our 
manufacturing operations, thereby adversely affecting our revenues, profitability and financial condition”, 
and for more information on the impact on our business of the armed conflict in Ukraine, see “Risk Factors - 
Risks Relating to Our Business and Industry - Armed conflicts, such as the Russia-Ukraine war, may adversely 
affect our operations”. 
 
On November 1, 2023, the Company’s board of directors approved an investment plan to build a second 
wind farm in Argentina at a cost of approximately $214 million, which would supply a further 30% of the 
current energy requirements of the facilities in Campana and reduce the CO2 emissions by a further 102,500 
tons per year. This investment is expected to be completed during 2025.

Other Investments 
Ternium 
As of December 31, 2024, the Company held 11.46% of Ternium’s share capital, representing 11.70% of its 
voting rights. Ternium is a Luxembourg company controlled by San Faustin, whose securities are listed on the 
NYSE. 
 
The Company is a party to a shareholders’ agreement with Techint Holdings S.àr.l. (“Techint Holdings”), a 
wholly owned subsidiary of San Faustin and Ternium’s main shareholder, dated January 9, 2006, pursuant to 
which Techint Holdings is required to take actions within its power to cause one of the members of Ternium’s 
board of directors to be nominated by the Company and any directors nominated by the Company to be 
removed only pursuant to previous written instructions from the Company. The Company and Techint 
Holdings also agreed to cause any vacancies on Ternium’s board of directors to be filled with new directors 
nominated by either the Company or Techint Holdings, as applicable. The shareholders’ agreement will 
remain in effect so long as each of the parties holds at least 5% of the shares of Ternium or until it is 
terminated by either the Company or Techint Holdings pursuant to its terms. Pursuant to this shareholders 
agreement, Carlos Condorelli currently serves as the Company-nominated director of Ternium; and Alicia 
Móndolo has been nominated as the new Company-nominated director of Ternium, to be appointed at the 
next annual general meeting of shareholders of Ternium that will be held on May 6, 2025.  
 
The following factors and circumstances evidence that Tenaris has significant influence over Ternium: 
  
• 
four out of eight members of Ternium’s board of directors (including Ternium’s chairman) are also 
members of the Company’s board of directors; and 
• 
both the Company and Ternium are under the indirect common control of San Faustin S.A. (“San 
Faustin”) and under the shareholders’ agreement by and between the Company and Techint Holdings 
S.àr.l ("Techint"), a wholly owned subsidiary of San Faustin and Ternium’s controlling shareholder, dated 
January 9, 2006 Techint, is required to take actions within its power to cause (a) one of the members of 
Ternium’s board of directors to be nominated by the Company and (b) any director nominated by the 
Company to be removed from Ternium’s board of directors only pursuant to previous written instructions 
of the Company. 
 
Usiminas 
At December 31, 2024, Tenaris held, through its Brazilian subsidiary, Confab, 47.5 million ordinary shares 
and 1.3 million preferred shares of Usiminas, representing 6.76% of its shares with voting rights, 3.96% of 
its total share capital, and 9.8% of Usiminas’ control group. 
 
Confab’s participation in Usiminas share capital is the result of a series of acquisitions, the first of which was 
completed on January 16, 2012, pursuant to which Ternium (through its subsidiaries Ternium Investments 
and Ternium Argentina) and Confab acquired a large block of Usiminas ordinary shares and joined Usiminas’ 
existing control group. Subsequently, in 2016, Ternium and Confab subscribed to additional ordinary shares 
and to preferred shares. 
 
On July 3, 2023, Confab, together with Ternium (through its subsidiaries Ternium Investments and Ternium 
Argentina), acquired an additional 68.7 million ordinary shares of Usiminas, at a price of BRL10 per ordinary 
share. Tenaris paid approximately BRL110 million (approximately $22.7 million) in cash for approximately 11 
million ordinary shares, increasing its participation in the Usiminas control group to 9.8%. 
 
The Usiminas control group comprises the T/T Group that is formed by Ternium Investments, Ternium 
Argentina and Confab; the NSC Group, comprising NSC, Mitsubishi and MetalOne; and Usiminas’ employee 
pension fund, Previdência Usiminas. 
 
At December 31, 2024, the Usiminas control group held, in the aggregate, 483.6 million ordinary shares, 
representing approximately 68.6% of Usiminas’ voting capital and the T/T Group held an aggregate 
participation of 61.3% in the control group (with 51.5% of the Usiminas’ control group’s participation 
corresponding to Ternium’s subsidiaries, and the remaining 9.8% corresponding to Confab); the NSC Group 
and Previdência Usiminas held 31.7% and 7%, respectively, in Usiminas’ control group.  
 

Annual Report 2024 
69 
Upon closing of the July 3, 2023 acquisition, the then existing Usiminas shareholders agreement governing 
the relationship between the T/T Group, the NSC Group and Previdência Usiminas was replaced by a new 
shareholders agreement setting forth a new governance structure for Usiminas. The T/T Group is now entitled 
to nominate a majority of the Usiminas board of directors, the chief executive officer and four other members 
of Usiminas’ board of officers. Of the positions allocated to the T/T Group, Tenaris retains the right to 
nominate one member of Usiminas’ board of directors and one member of Usiminas’ board of officers. 
Ordinary decisions may be approved with a 55% majority of Usiminas’ control group shares.  
 
At any time after the second anniversary of the closing of the transaction, the T/T Group will have the right to 
buy the NSC Group’s remaining interest in the Usiminas’ control group (153.1 million ordinary shares) at the 
higher of $2.0584 per share and the equivalent in U.S. dollars of the 40-trading day average price per share 
immediately prior to the date of exercising the option. In addition, the NSC Group will have the right, at any 
time after the closing of the transaction, to withdraw its remaining shares from the control group and sell 
them in the open market after giving the T/T Group the opportunity to buy them at the equivalent in U.S. 
dollars of the 40-trading day average price per share immediately prior to the NSC group’s notice of 
withdrawal, as well as the right, at any time after the second anniversary of the closing, to sell such shares to 
the T/T Group at $2.0584 per share. Confab will have the right (but not the obligation) to participate in each 
such transaction pro rata to its current participation in the T/T Group. 
 
Confab and the Ternium entities party to the Usiminas shareholders agreement have a separate shareholders 
agreement governing their respective rights and obligations as members of the T/T Group. Under such 
separate agreement, Confab enjoys certain rights with respect to the governance of Usiminas, including, 
among others, the ability to nominate certain of Usiminas’ officers and directors. These facts evidence that 
Tenaris continues to have significant influence over Usiminas and, as a result, continues accounting for its 
investment under the equity method. 
 
Techgen 
Techgen is a Mexican joint venture company owned 48% by Ternium, 30% by Tecpetrol and 22% by 
Tenaris. Techgen operates a natural gas-fired combined cycle electric power plant in the Pesquería area of the 
State of Nuevo León, Mexico. Tenaris, Ternium and Tecpetrol are parties to a shareholders’ agreement 
relating to the governance of Techgen. 
 
In the last few years, the Mexican government made various attempts to modify rules and regulations 
governing the energy market in Mexico with potential impact on the energy supply and its cost. For more 
information on the risks associated with the energy reform in Mexico, see “Risk Factors - Risks Relating to 
Our Business and Industry - Adverse economic or political conditions in the countries where we operate or sell 
our products and services may decrease our sales or disrupt our manufacturing operations, thereby adversely 
affecting our revenues, profitability and financial condition”.

Operating and Financial Review and Prospects 
 
The following discussion and analysis of our financial condition and results of operations are based on, and 
should be read in conjunction with, our audited consolidated financial statements and the related notes 
included elsewhere in this annual report. This discussion and analysis present our financial condition and 
results of operations on a consolidated basis. We prepare our consolidated financial statements in conformity 
with IFRS. IFRS differ in certain significant respects from U.S. GAAP. 
Certain information contained in this discussion and analysis and presented elsewhere in this annual report, 
including information with respect to our plans and strategy for our business, includes forward-looking 
statements that involve risks and uncertainties. See “Cautionary Statement Concerning Forward-Looking 
Statements”. In evaluating this discussion and analysis, you should specifically consider the various risk factors 
identified in “Risk Factors”, other risk factors identified elsewhere in this annual report and other factors that 
could cause results to differ materially from those expressed in such forward-looking statements. 
Overview 
Our main source of revenue is the sale of products and services to the oil and gas industry, and the level of 
such sales is sensitive to international oil and gas prices and their impact on drilling activities 
Demand for our products and services from the global oil and gas industry, particularly for tubular products 
and services used in drilling operations, represents a substantial majority of our total Tubes sales. Our sales, 
therefore, depend on the condition of the oil and gas industry and our customers’ willingness to invest capital 
in oil and gas exploration and production as well as in associated downstream processing activities. The level 
of these expenditures is sensitive to oil and gas prices as well as the oil and gas industry’s view of such prices 
in the future. 
Our business is highly competitive 
The global market for steel pipes is highly competitive, with the primary competitive factors being price, 
quality, service and technology. We sell our products in a large number of countries worldwide and compete 
primarily against European and Japanese producers in most markets outside North America. In the United 
States and Canada, we compete against a wide range of local and foreign producers. Over the past two 
decades, substantial investments have been made, especially in China but also in other regions around the 
world, to increase production capacity of seamless steel pipe products. 
Our production costs are sensitive to prices of steelmaking raw materials and other steel products 
We purchase substantial quantities of steelmaking raw materials, including ferrous steel scrap, DRI, pig iron, 
iron ore and ferroalloys, for use in the production of our seamless pipe products. In addition, we purchase 
substantial quantities of steel coils and plates for use in the production of our welded pipe products. Our 
production costs, therefore, are sensitive to prices of steelmaking raw materials and certain steel products, 
which reflect supply and demand factors in the global steel industry and in the countries where we have our 
manufacturing facilities.  
Summary of results 
Our sales in 2024 amounted to $12.5 billion with a decrease of 16% compared to 2023, primarily reflecting 
a decline in market prices for our tubular products used in onshore drilling applications in the Americas, lower 
drilling activity in Mexico and Colombia, lower shipments for pipeline projects in Argentina and lower sales of 
mechanical pipes in Europe. On the other hand, sales in the Middle East reached a record level as Saudi 
Aramco replenished OCTG stocks and increased gas drilling activity. EBITDA1 and margins also declined to 
$3.1 billion, being further affected by a $107 million loss from a provision for the ongoing litigation related 
to the acquisition of a participation in Usiminas. Net income amounted to $2.1 billion, or 17% of net sales, 
and was affected by a reduction of $43 million from our participation in Ternium related to the same case.

Cash flow provided by operating activities amounted to $2.9 billion during 2024. This was used to fund 
capital expenditures of $694 million, with the remainder distributed to shareholders through dividend 
payments of $758 million and share buybacks for $1,440 million in the year. We maintained a net cash 
position2 of $3.6 billion at the end of December 2024. 
Outlook 
Oil prices remain relatively stable (as they have done over the past two years) with OPEC+ maintaining their 
voluntary production cuts in the face of limited global demand growth. European and US natural gas prices 
have, however, risen as relatively cold winter weather and the cutoff of Russian supply have led to a rapid 
drawdown in inventories. 
 
These prices and the continuing balance between oil and gas demand and supply should continue to support 
overall investment in oil and gas drilling activity, as well as OCTG demand, at current levels, albeit with some 
regional nuances. 
 
In North America, consolidation among major operators and drilling efficiencies led to a drop in US drilling 
activity last year, which has now stabilized, while OCTG consumption per rig has been increasing. In Latin 
America, drilling activity is increasing in Argentina, as investment in pipeline and LNG infrastructure 
investment for the Vaca Muerta shale moves forward, while, in Mexico, it has been affected by financial 
constraints on Pemex. In the Middle East, some reduction in oil drilling has taken place in Saudi Arabia while 
gas drilling has risen, and, in Abu Dhabi, oil drilling is increasing. 
 
OCTG reference prices in North America, which fell steadily for two years until the second half of 2024, have 
so far recovered by 9% from their August low and could rise further following the US government’s 
announced reset of Section 232 tariffs on all imports of steel products without exception. 
 
In this environment, we expect our sales and EBITDA3 (excluding extraordinary effects) in the first quarter of 
2025 to be in line with those of the last quarter of 2024 before rising moderately in the second quarter of 
2025. Beyond that, likely changes in US tariffs and their possible ramifications on trade flows will introduce a 
new dynamic with a high level of uncertainty for costs and prices to our results.

Net sales of tubular products and services decreased 16% to $11,907 million in 2024, compared to $14,185 
million in 2023 due to a 5% decrease in volumes and a 12% decrease in average selling prices, primarily 
reflecting a decline in market prices for our tubular products used in onshore drilling applications in the 
Americas, lower drilling activity in Mexico and Colombia, lower shipments for pipeline projects in Argentina 
and lower sales of mechanical pipes in Europe. On the other hand, sales in the Middle East reached a record 
level as Saudi Aramco replenished OCTG stocks and increased gas drilling activity, while sales in Europe were 
boosted by an exceptional level of sales for offshore and onshore projects in Turkey. 
 
Operating results from tubular products and services amounted to a gain of $2,305 million in 2024 compared 
to a gain of $4,183 million in 2023. The decline in operating results is mainly due to the decline in average 
selling prices and the corresponding impact on sales and margins. Additionally, in 2024 our Tubes operating 
income includes a charge of $107 million from the provision for the ongoing litigation related to the 
acquisition of a participation in Usiminas, included in other operating expenses.

a gain of $133 million in 2023. 
Selling, general and administrative expenses, or SG&A, amounted to $1,905 million in 2024, representing 
15.2% of sales, and $1,919 million in 2023, representing 12.9% of sales. SG&A expenses increased as a 
percentage of sales due to the 16% decline in revenues, mainly due to lower Tubes average selling prices and 
an increase of fixed costs. 
Other operating results amounted to a loss of $65 million in 2024, compared to a gain of $36 million in 
2023. In 2024 we recorded a $107 million loss from provision for the ongoing litigation related to the 
acquisition of a participation in Usiminas. In 2023 other operating income includes a non-recurring gain of 
$33 million corresponding to the transfer of the awards related to the Company’s Venezuelan nationalized 
assets. 
Financial results amounted to a gain of $129 million in 2024, compared to a gain of $221 million in 2023. 
While net finance income increased due to a higher net financial position, net foreign exchange results 
decreased significantly in respect to the previous year. 
Equity in earnings of non-consolidated companies generated a gain of $9 million in 2024, compared to a 
gain of $95 million in 2023. These results were mainly derived from our equity investment in Ternium 
(NYSE:TX) and in 2024 were negatively affected by a $43 million loss from the provision for the ongoing 
litigation related to the acquisition of a participation in Usiminas on our Ternium investment. 
Income tax amounted to a charge of $480 million in 2024, compared to $675 million in 2023. The lower 
income tax charge mainly reflects the reduction in results at several subsidiaries.

Net sales of tubular products and services increased 27% to $14,185 million in 2023, compared to $11,133 
million in 2022, reflecting a 17% increase in volumes and a 9% increase in average selling prices. Volumes 
increased mainly in the AMEA region following an increase in activity and in South America mainly due to the 
delivery of welded line pipe for a gas pipeline in Argentina. Prices were higher in all regions. 
Operating results from tubular products and services, amounted to a gain of $4,183 million in 2023, 
compared to a gain of $2,867 million in 2022 (which was net of a $63 million impairment charge). The 
improvement in operating results was driven by the recovery in shipment volumes and in prices which helped 
to compensate for an increase in costs.

Net sales of other products and services increased 9% from $630 million in 2022 to $684 million in 2023, 
which includes $77 million from the pipe coating business unit acquired from Mattr on November 30, 2023. 
Additionally, in 2023 we had higher sales from our oilfield services business in Argentina, sucker rods and 
coiled tubing services, which offset the decline in sales of excess raw materials and energy and pipes for 
plumbing applications in Italy. 
 
Operating results from other products and services amounted to a gain of $133 million in 2023, compared to 
$96 million in 2022. Results were mainly derived from our sucker rods business and our oilfield services 
business in Argentina. 
 
Selling, general and administrative expenses, or SG&A, amounted to $1,919 million (12.9% of net sales) in 
2023, compared to $1,635 million (13.9%) in 2022. The 2023 increase in SG&A is mainly due to higher labor 
costs and logistic costs (freights and taxes), although they decreased as a percentage of sales. 
 
Financial results amounted to a gain of $221 million in 2023, compared to a loss of $6 million in 2022. 2023 
results are mainly derived from net foreign exchange gains of $209 million, mainly related to the positive 
effect of the devaluation of the ARS over a net short exposure in that currency. These positive FX results were 
partially offset by a $95 million loss from the change in the fair value of U.S. dollar-denominated Argentine 
bonds when distributed and disposed abroad. Additionally, our net cash position4 yielded a net interest gain 
of $107 million in the year. 
 
Equity in earnings of non-consolidated companies generated a gain of $95 million in 2023, compared to 
$209 million in 2022. These results were mainly derived from our equity investment in Ternium (NYSE:TX). 
The result of 2023 includes a non-cash loss of $144 million from our investment in Usiminas ($26 million 
from our direct investment in Usiminas and $118 million from our indirect investment in Usiminas through 
Ternium), related to the fair value measurement of the shares and the result of recycling Ternium´s negative 
accumulated currency translation reserve to the income statement. In 2022, equity in earnings of non-
consolidated companies included a $34 million impairment charges on our participations in the joint venture 
with Severstal ($15 million) and in Usiminas ($19 million). 
 
Income tax charge amounted to $675 million in 2023, compared to $617 million in 2022, reflecting the 
improvement in results in several subsidiaries and a net positive deferred tax effect of $194 million.

Our financing strategy aims to maintain adequate financial resources and access to additional liquidity. 
During 2024, cash flow provided by operating activities amounted to $2,866 million (including a decrease in 
working capital of $287 million), we re-purchased $1.4 billion of our shares under the buy-back programs, 
our capital expenditures amounted to $694 million, and we paid dividends amounting to $758 million. At the 
end of the year, we had a net cash position5 of $3.6 billion, compared to $3.4 billion at the beginning of the 
year. 
We believe that funds from operations, the availability of liquid financial assets and our access to external 
borrowing through the financial markets will be sufficient to satisfy our working capital needs, to finance our 
planned capital spending program as well as to service our debt in the future twelve months and to address 
short-term changes in business conditions. 
We have a conservative approach to the management of our liquidity, which consists of (i) cash and cash 
equivalents (cash in banks, liquidity funds and investments with a maturity of less than three months at the 
date of purchase), and (ii) other investments (fixed income securities, time deposits, and fund investments). 
As of December 31, 2024, liquid financial assets as a whole (comprising cash and cash equivalents and other 
investments) were 20% of total assets compared to 19% at the end of 2023. 
We hold investments primarily in liquidity funds and variable or fixed-rate securities from investment grade 
issuers. 
 
We hold our cash and cash equivalents primarily in U.S. dollars and in major financial centers. As of 
December 31, 2024, and December 31, 2023, U.S. dollar denominated liquid assets, plus investments 
denominated in other currencies hedged to the U.S. dollar, represented 93% and 84% of total liquid 
financial assets, respectively.

Operating activities 
 
Net cash provided by operations during 2024 amounted to $2,866 million, compared to $4,395 million 
during 2023. This decrease was mainly attributable to a lower income for the year in 2024, which amounted 
to $2.1 billion in 2024 and $4.0 billion in 2023. Working capital variation showed a reduction of $287 million 
in 2024, while in 2023 there was a working capital decrease of $182 million. For more information on cash 
flow disclosures and changes to working capital, see note 30 “Cash flow disclosures” to our audited 
consolidated financial statements included in this annual report. 
 
Investing activities 
 
Net cash used in investing activities amounted to $1,397 million in 2024, compared to net cash used in 
investing activities of $2,687 million in 2023. In 2024, we increased our financial investments by $821 million 
compared to an increase of $1,857 million in 2023, while capital expenditures amounted to $694 million in 
2024 compared to $619 million in 2023. In 2024, we received $31 million related to post-closing purchase 
price adjustments of a completed acquisition, while in 2023 we paid $266 million in acquisitions. 
 
Financing activities 
 
Net cash used in financing activities amounted to $2,399 million in 2024, compared to $1,125 million in 
2023. In 2024, we repurchased Company shares, under share buyback programs, for an amount of $1.4 
billion, whereas in 2023, we repurchased $0.2 billion of Company shares. Dividends paid during 2024 
amounted to $758 million and to $637 million during 2023. During 2024, we had net repayments of 
borrowings of $129 million, while in 2023 we had net repayments from borrowings of $208 million.  
 
Our total liabilities to total assets ratio was 0.18:1 as of December 31, 2024, and 0.19:1 as of December 31, 
2023. 
 
Fiscal Year Ended December 31, 2023, Compared to Fiscal Year Ended December 31, 2022 
 
Operating activities 
 
Net cash provided by operations during 2023 amounted to $4,395 million, compared to $1,167 million 
during 2022. This increase was mainly attributable to the working capital variation which amounted to a 
reduction of $182 million in 2023, while in 2022 there was a working capital increase of $2,131 million. The 
annual variation in working capital was mainly attributed to a decrease of $187 million in inventories and 
$154 million in trade receivables, partially offset by a decrease of $149 million in trade payables and $102 
million in customer advances, compared to an increase of $1,330 million in inventories and $1,208 million in 
trade receivables in 2022. The increase in net cash provided by operations is also due to better results, as net 
income amounted to $3,958 million in 2023, compared to a net income of $2,549 million in 2022. For more 
information on cash flow disclosures and changes to working capital, see note 30 “Cash flow disclosures” to

Trend Information 
 
Principal Factors Affecting Oil and Gas Prices and Demand for Steel Pipes from the Global Oil and Gas 
Industry 
 
Sales to the oil and gas industry worldwide represent a high percentage of our total sales, and demand for 
steel pipes from the global oil and gas industry is a significant factor affecting the general level of volumes 
and prices for our products. Downward pressures on oil and gas prices usually result in lower oil and gas 
drilling activity and investment throughout the oil and gas industry with consequently lower demand for our 
steel pipe products and, in some circumstances, upward pressures can result in higher demand from our oil 
and gas customers. 
 
Whereas oil prices are similar in most parts of the world because oil is a fully tradable commodity, gas prices 
are influenced by regional factors. In North America, where gas production is extensively developed and there 
is an extensive regional pipeline system, these factors include available gas storage capacity and seasonal 
weather patterns, particularly winter temperatures in the United States. LNG prices have been traditionally 
established in relation to international oil prices, particularly in the largest LNG markets in Asia. However, as 
the market for LNG has become more global and the United States has become a major source of LNG, LNG 
prices are now being set increasingly in relation to gas prices prevailing at regional gas hubs. In 2022, spot 
LNG prices completely decoupled from oil prices as pipeline gas imports to Europe from Russia were 
substantially reduced consequent to the Russian invasion of Ukraine and European countries dramatically 
increased imports of LNG to replace Russian gas. LNG prices have since normalized, but remain relatively high 
as European storage levels have been rapidly drawn down in the recent winter heating season and are 
required to be replenished to 90% of capacity by the next winter season. 
 
International oil prices depend on diverse factors. On the supply side, major oil-and-gas-producing nations 
and companies have frequently collaborated to balance the supply (and thus the price) of oil in the 
international markets. A major vehicle for this collaboration has been OPEC, and more recently what has 
become known as OPEC+, which includes OPEC members, plus Russia and certain other countries. Many of 
our customers are state-owned companies in member countries of OPEC and OPEC+. Another factor that has 
affected the international price level of oil is the political and socioeconomic conditions of oil-producing 
countries, such as Libya, Nigeria and Venezuela and the persistence of geo-political and armed conflicts, such 
as the recent Ukraine-Russia armed conflict, and conflicts affecting the Middle East region, which is home to 
a substantial proportion of the world’s known oil reserves. See “Risk Factors – Risks Relating to Our Business 
and Industry – Armed conflicts, such as the Russia-Ukraine war, may adversely affect our operations”. 
 
On the demand side, economic conditions and the level of oil inventories have traditionally played a role in oil 
prices and will continue to do so. Eventually, however, the rate of substitution of oil and gas by alternative, 
cleaner fuel sources such as renewables, as well as policies adopted by governments and financing entities 
worldwide to advance the energy transition and by oil and gas companies to adapt their strategies to the 
energy transition, are likely to also play a role in oil prices. 
 
Another factor affecting oil and gas prices has been the ability of producers in the United States and Canada 
to rapidly increase production from their reserves of tight oil and shale gas in response to changes in market 
conditions. Production from U.S. tight oil reserves has grown in recent years to represent over 15% of global 
liquids production, and production from shale gas plays has converted the United States into the largest 
exporter of natural gas in the LNG market. 
 
In 2020, the COVID-19 pandemic caused a sudden and precipitous drop in global oil demand and oil prices 
collapsed even entering negative territory at one point. Since then, prices have recovered above their pre-
pandemic level with the recovery in demand and actions by OPEC member countries and other producers to 
cut and then gradually increase production levels. In addition, energy and commodity prices spiked upwards 
at the onset of the armed conflict involving Russia and Ukraine although they have subsequently fallen back. 
LNG prices, fell back at the end of 2022 and beginning of 2023 reflecting unusually warm winter weather 
conditions and reduced industrial demand in Europe which resulted in far lower drawdowns from storage 
than is customary for this period of the year, but increased during 2024 and early 2025, as colder winter 
weather conditions led to a rapid drawdown of gas in storage. For more information on the impact of the 
armed conflict in Ukraine, see “Risk Factors - Risks Relating to Our Business and Industry - Armed conflicts, 
such as the Russia-Ukraine war, may adversely affect our operations”. 
 
 

Annual Report 2024 
83 
The collapse of oil prices, in March 2020 took place when oil and gas operators, particularly in the United 
States, were already reducing their investments and drilling activity in response to pressure from financial 
markets to generate positive free cash7 flows. Oil and gas operators around the world then made further 
substantial reductions in their exploration and production investments, reducing them to a level around 70% 
of their pre-pandemic level. Investments have subsequently recovered to their pre-pandemic level in 2023 and 
have remained there. 
 
Since the development of the prolific Marcellus shale gas play, North American gas prices have remained at 
low levels compared to previous decades and relative to other major gas-consuming regions and global LNG 
prices. For several years, production increases, primarily from productive shale gas deposits, have exceeded 
regional demand increases, reducing the need for imports, to the extent that, in 2017, the United States 
became a net exporter of natural gas. Low prices have encouraged investment in gas consuming industrial 
facilities and LNG export facilities as well as switching from coal to gas for electric power production, 
particularly with the adoption of new regulations which could force the retirement of older coal-based 
generating units. With continuing investments in LNG export facilities, the United States has become the 
world’s largest global LNG exporter. 
 
Until the Russian invasion of Ukraine, LNG prices used to reflect supply and demand conditions in Asia, the 
major LNG-consuming region, although demand had been increasing in regions like Europe, which imports 
LNG to supplement its traditional pipeline imports from Russia and other neighboring gas-producing regions, 
and South America, which imports LNG in its winter season and to supplement hydroelectric energy when 
rainfall is low. In 2022, however, Europe became a major competitor to Asia in the LNG market as it sought 
to replace Russian pipeline gas at almost any cost. As Europe phased out imports of pipeline gas from Russia, 
demand for LNG in Europe has grown, and this is changing the price dynamics of the industry. Demand, 
however, has been affected by a decline in industrial activity in Europe, and spot LNG fell back in 2023 to 
levels below oil parity on a relatively warm winter heating season but have since increased. Consumption, 
though not necessarily prices, will continue to show seasonal fluctuations, increasing in the North Asian and 
European winter period and declining in the summer months. The efforts to fill European storage capacity 
and increase import capacity has, however, increased price volatility. 
 
U.S. natural gas prices increased during 2021, reaching $6 per million BTU as LNG export capacity came on 
stream and demand increased. In late 2022 and 2023, prices returned to a level of $2-3 per million BTU as 
LNG export demand was capped by capacity limitations and the temporary shutdown of a facility while 
domestic demand during the winter heating season was lower than usual. In 2024, they dipped even further 
on another warm winter, but, in early 2025, they have risen to around $4 per million BTU on higher demand 
due to colder winter weather and the prospect of more LNG export capacity availability later in the year. 
 
Drilling activity in the United States and Canada, following several years of high activity, fell sharply through 
2015 and the first half of 2016 before beginning a recovery which ended at the end of 2018. Drilling activity 
declined throughout 2019 in response to a fall in oil prices at the end of 2018 and financial market pressures 
to produce positive cash flow returns. This decline turned into a collapse with the onset of the COVID-19 
pandemic in 2020. Since then, there was a steady recovery through 2021 and 2022, before rigs gradually fell 
through 2023 and most of 2024, even as production levels continued to increase. Production levels today are 
at record levels but rig counts are much lower than before the 2014 collapse of oil prices and in 2019 pre-
pandemic, reflecting the strong productivity gains and the consolidation made in the U.S. oil and gas drilling 
industry. Latin American drilling followed a similar cycle. In the Eastern Hemisphere, drilling activity tends to 
follow a delayed and more gradual pattern in respect of changes in the oil price considering the longer-time 
investment cycle of offshore and conventional drilling projects. Thus, the decline in Eastern Hemisphere 
drilling activity following the pandemic-induced collapse in oil prices came in 2021 and the recovery began in 
2022 and extended through the middle of 2024. 
 
Prior to the 2014 downturn in oil prices, a growing proportion of exploration and production spending by oil 
and gas companies had been directed at offshore, deep drilling and non-conventional drilling operations in 
which high-value tubular products, including special steel grades and premium connections, are usually 
specified. The success, however, of shale drilling operators, with their inherently short investment cycles, in 
adapting to lower oil and gas prices and increasing production, led to a slowdown in new developments of 
complex offshore projects with long investment lead times in a context of low and more volatile oil prices, 
consequently affecting the level of product differentiation. More recently, however, since 2022, offshore 
drilling activity has been increasing again as exploration has continued and cost-competitive developments,

like those in Brazil, Guyana, and sub-Saharan Africa, are sanctioned and developed, and, in the United States, 
new high pressure 20 ksi drilling technologies is opening up access to cost-competitive deepwater reserves.  
 
In addition, the increasing cost competitiveness and use of alternative renewable sources of energy will limit 
growth in demand for oil and gas and put downward pressure on oil and gas prices in the longer term. This 
trend will accelerate if carbon taxes or carbon pricing instruments resulting in high prices for carbon 
emissions, or other regulations aimed at reducing the use of fossil fuels, are implemented around the world. 
There has been a substantial increase in the number of commitments to reduce carbon emissions from 
governments and public companies, including those operating in the oil and gas industry, and calls on 
governments and financial entities to introduce regulations and policies to accelerate the energy transition 
away from fossil fuels to cleaner sources of energy. Major oil and gas companies have been adapting their 
strategies to address the energy transition and some have even set out commitments to reduce production, 
although, more recently, they are rowing back on such commitments. For more information on climate 
change regulations, see “Risk Factors - Risks Relating to Our Business and Industry - Climate change 
legislation and increasing regulatory requirements aimed at transitioning to a lower-carbon economy may 
reduce demand for our products and services and result in unexpected capital expenditures and costs, and 
negatively affect our reputation”. 
 
On the other hand, we expect that the energy transition will create new markets for the use of our products 
and services including for drilling geothermal wells, in the transportation and storage of hydrogen and for 
CCS systems. We constantly monitor the evolution of the strategies of our main customers and scenarios for 
future energy demand, considering the global objectives for addressing climate change through the reduction 
of carbon emissions in accordance with the Paris Agreement and national objectives to achieve carbon-
neutrality. We also assess the market outlook for our products with reference to the different scenarios for oil 
and gas demand published by our customers, international agencies such as the IEA and expert energy 
market consultancies such as Rystad. These assessments are used as fundamental input for evaluating our 
business strategy and how to address the risks and opportunities arising from climate change. 
 
The tables below show the annual average number of active oil and gas drilling rigs, or rig count, in the

Critical Accounting Estimates 
 
This discussion and analysis of our financial condition and results of operations is based on our audited 
consolidated financial statements, which have been prepared in accordance with IFRS. IFRS differs in certain 
significant aspects from U.S. GAAP. 
The preparation of our audited consolidated financial statements and related disclosures in conformity with 
IFRS requires us to make estimates and assumptions that might affect the reported amounts of assets and 
liabilities, the disclosure of contingent liabilities and the reported amounts of revenue and expenses. 
Management evaluates its accounting estimates and assumptions, including those related to impairment 
testing of long-lived assets; impairment in investment in associates; income taxes including recoverability of 
deferred tax assets; obsolescence of inventory; contingencies; allowance for trade receivables; post-
employment and other long-term benefits; business combinations; useful lives of property, plant and 
equipment and other long-lived assets; fair value estimation of certain financial instruments and property title 
ownership restriction, and revises them when appropriate. Management bases its estimates on historical 
experience and on various other assumptions it believes to be reasonable under the circumstances. These 
estimates form the basis for making judgments about the carrying values of assets and liabilities that are not 
readily apparent from other sources. Although management believes that these estimates and assumptions 
are reasonable, they are based upon information available at the time they are made. Actual results may 
differ significantly from these estimates under different assumptions or conditions. For more information, see 
“II. Accounting Policies” to our consolidated financial statements included in this annual report. 
Functional and presentation currency 
The functional and presentation currency of the Company is the U.S. dollar. The U.S. dollar is the currency 
that best reflects the economic substance of the underlying events and circumstances relevant to Tenaris’s 
global operations. 
Starting January 1, 2023, the Company changed the functional currency of its Brazilian subsidiaries, from the 
Brazilian Real to the U.S. dollar. 
Except for its Italian subsidiaries whose functional currency is the Euro and two subsidiaries whose functional 
currencies are the Canadian Dollar and the Norwegian Krone, Tenaris determined that the functional 
currency of its other subsidiaries is the U.S. dollar, based on the following principal considerations:

sales are mainly negotiated, denominated and settled in U.S. dollars. If priced in a currency other than 
the U.S. dollar, the sales price may consider exposure to fluctuation in the exchange rate versus the 
U.S. dollar; 
• 
prices of critical raw materials and inputs are priced and settled in U.S. dollars; 
• 
transaction and operational environment and the cash flow of these operations have the U.S. dollars as 
reference currency; 
• 
significant level of integration of local operations within Tenaris’s international global distribution 
network; and 
• 
net financial assets and liabilities are mainly received and maintained in U.S. dollars. 
Results of operations for subsidiaries whose functional currencies are not the U.S. dollar are translated into 
U.S. dollars at the average exchange rates for each quarter of the year. Financial statement positions are 
translated at the year-end exchange rates. Translation differences are recognized in a separate component of 
equity as currency translation adjustments. In the case of a sale or other disposal of any of such subsidiaries, 
any accumulated translation difference would be recognized in the consolidated income statement as a gain 
or loss from the sale or disposal.

Corporate Governance Statement 
The Company’s corporate governance practices are governed by Luxembourg Law, including, among others, 
the Luxembourg Company Law, the Luxembourg Law of January 11, 2008 on transparency requirements for 
issuers (which transposes EU Directive 2004/109 of the European Parliament and of the Council of December 
15, 2004) (the “Transparency Law”), the Luxembourg Law of August 1, 2019 on the exercise of certain rights 
of shareholders in general meetings of listed companies (which transposes EU Directive 2017/828 of the 
European Parliament and of the Council of May 17, 2017) (the “Shareholders’ Rights Law”), and the 
Luxembourg law of July 23, 2016, concerning the audit profession (the “Audit Reform Law”) and by the 
Company’s articles of association. The following is a summary of certain rights of holders of the Company’s 
shares and includes the information required under the Luxembourg Law on takeovers of May 19, 2006. 
Shareholders’ rights are set out in the Company’s articles of association and are provided by applicable 
Luxembourg law and may differ from those typically provided to shareholders of U.S. companies under the 
corporation laws of some states of the United States. This summary is not exhaustive and does not contain all 
the information that may be important to investors. For more complete information, you should read the 
Company’s articles of association, which are attached as an exhibit to this annual report. 
Corporate Governance 
 
Memorandum and Articles of Association 
The Company is a public limited liability company (société anonyme) organized under the laws of 
Luxembourg, registered under the number B85 203 in the Luxembourg Registre de Commerce et des 
Sociétés. Its object and purpose, as set forth in Article 2 of its articles of association, is the taking of interests, 
in any form, in corporations or other business entities, and the administration, management, control and 
development thereof. 
The Company’s authorized share capital is fixed by the Company’s articles of association as amended from 
time to time with the approval of shareholders at an extraordinary general shareholders’ meeting. The 
Company has an authorized share capital of a single class of 2,500,000,000 shares having a nominal value of 
USD1.00 per share. There were 1,162,757,528 shares issued as of the date of this annual report, including 
treasury shares. All issued shares are fully paid. As at the end of the second, third and fourth tranches of the 
initial share buyback program and as the end of the follow-on share buyback program, the Company had 
repurchased 90,762,598 shares which are expected to be cancelled in the upcoming extraordinary 
shareholders meeting scheduled to be held on May 6, 2025. 
The Company’s articles of association authorize the board of directors, or any delegate(s) duly appointed by 
the board of directors, to issue shares within the limits of the authorized share capital against contributions in 
cash, contributions in kind or by way of available reserves, at such time and on such terms and conditions, 
including the issue price, as the board of directors, or its delegate(s), may in its or their discretion resolve.  
The Company’s extraordinary shareholders’ meeting held on June 2, 2020 approved the renewal for an 
additional five-year period of the authorization granted to the board of directors to waive, suppress or limit 
any preemptive subscription rights of shareholders provided for by law to the extent it deems such waiver, 
suppression or limitation advisable for any issue or issues of shares within the authorized share capital; and 
have waived any preemptive subscription rights provided for by law and related procedures. Although the 
validity period of such authorization will expire on June 12, 2025, the board of directors has convened an 
extraordinary meeting of shareholders to be held on May 6, 2025, which will consider the renewal of such 
authorization for an additional five-year period. However, under the Company’s articles of association, the 
Company’s existing shareholders shall have a preferential right to subscribe for any new shares issued 
pursuant to the authorization granted to its board of directors, except in the following cases (in which cases 
no preemptive subscription rights shall apply): 
• 
any issuance of shares (including, without limitation, the direct issuance of shares or upon the exercise 
of options, rights convertible into shares, or similar instruments convertible or exchangeable into 
shares) against a contribution other than in cash; and 
• 
any issuance of shares (including by way of free shares or at discount), up to an amount equal to 1.5% 
of the issued share capital of the Company, to directors, officers, agents or employees of the 
Company, its direct or indirect subsidiaries, or its affiliates, including, without limitation, the direct 
issuance of shares or upon the exercise of options, rights convertible into shares, or similar instruments 
convertible or exchangeable into shares, issued for the purpose of compensation or incentive for any 

Annual Report 2024 
87 
such persons or in relation thereto (which the board of directors shall be authorized to issue upon such 
terms and conditions as it deems fit). 
Amendment of the Company’s articles of association requires the approval of shareholders at an 
extraordinary shareholders’ meeting with a two-thirds majority vote of the shares represented at the meeting. 
The Company is controlled by San Faustin, which owns 61.37% of the Company’s issued share capital (and 
holds 65.81% of the voting rights) through its wholly owned subsidiary Techint Holdings S.à r.l. The Dutch 
private foundation (Stichting) RP STAK holds voting rights in San Faustin sufficient to control San Faustin. No 
person or group of persons controls RP STAK. 
As of December 31, 2024, (i) 31.80% of the Company’s issued share capital was publicly traded on the Italian 
Stock Exchange and the Mexican Stock Exchange; in addition, the Company’s ADSs trade on the NYSE; (ii) a 
0.07% was held by the Company’s directors and senior management as a group; and (iii) the remaining 6.75% 
of the Company’s issued share capital was held in treasury. See “Information on the Company - Major 
Shareholders and Related Party Transactions”. 
Dividends 
Subject to applicable law, all issued shares (including shares underlying ADSs) are entitled to participate 
equally in dividends when, as and if declared by the shareholders at the annual general shareholders’ 
meeting, out of funds legally available for such purposes. Treasury shares are not entitled to dividend 
distributions. 
Dividends may be lawfully declared and paid if the Company’s net profits and distributable reserves are 
sufficient under Luxembourg law. The amount and payment of dividends must be approved by a majority 
vote at a general shareholders’ meeting, generally, but not necessarily, based on the recommendation of the 
Company’s board of directors. Under Article 21 of the Company’s articles of association, the board of 
directors has the power to distribute interim dividends out of profits, share premium or any other available 
reserves, in accordance with applicable law, in particular in accordance with the conditions set forth in Article 
461-3 of the Luxembourg Company Law. Such dividend payments must be finally approved by the general 
shareholders’ meeting. On February 19, 2025 the Company announced that, upon approval of the 
Company’s annual accounts in April 2025, the board of directors intended to submit a proposal on dividends 
for approval of the annual general shareholders’ meeting to be held on May 6, 2025.  
As provided by Article 21 of the Company’s articles of association, dividends or other distributions declared 
by the general meeting as well as interim dividends or other distributions declared by the board of directors 
will be distributed at the times and places determined by the board of directors. The Company will make any 
and all dividend payments and any other distributions in respect of shares registered in the name of any 
securities settlement system or operator of such a system or in the name of any financial institution or other 
professional depositary of securities or any other depositary, whether in cash, shares or other assets, only to 
such registered holder, or otherwise in accordance with such registered holder’s instructions, and, as 
provided by Article 21 of the Company’s articles of association, that payment shall release the Company from 
any and all obligations for such payment. 
The Company conducts and will continue to conduct its operations through subsidiaries and, accordingly, its 
main source of cash to pay dividends, among other possible sources, will be the dividends received from its 
subsidiaries. For further information see “Risk Factors – Risks Relating to the Structure of the Company – The 
Company’s dividend payments depend on the results of operations and financial condition of its subsidiaries 
and could be restricted by legal, contractual or other limitations or tax changes”. 
 
Under Luxembourg law, claims for dividends will lapse in favor of the Company five years after the date such 
dividends are declared. However, the Company may elect to pay a declared dividend after such period. 
Declared and unpaid dividends held by the Company for the account of its shareholders do not bear interest. 
 
Pursuant to Luxembourg law, at least 5% of our net profits per year must be allocated to the creation of a 
legal reserve until such reserve has reached an amount equal to 10% of the Company’s issued share capital. 
If the legal reserve later falls below the 10% threshold, at least 5% (or such lower amount required to reach 
the 10% threshold) of net profits again must be allocated toward the reserve. As of December 31, 2024, the 
Company’s legal reserve represented 10% of its share capital. The legal reserve is not available for 
distribution.

Shareholders’ Meetings; Voting Rights; Election of Directors 
Each share entitles the holder thereof to one vote at the Company’s general shareholders’ meetings, provided 
that, under Luxembourg law, voting rights with respect to treasury shares shall be suspended for so long as 
such shares are held. Shareholder action by written consent is not permitted, but proxy voting is permitted. 
Notices of general shareholders’ meetings are governed by the provisions of Luxembourg law and the 
Company’s articles of association. Pursuant to applicable Luxembourg law, the Company must give notice of 
the calling of any general shareholders’ meeting at least 30 days prior to the date for which the meeting is 
being called, by publishing the relevant convening notice in the Recueil Electronique des Sociétés et 
Associations (Luxembourg’s electronic official gazette) and in a leading newspaper having general circulation 
in Luxembourg and by issuing a press release informing of the calling of such meeting. In case the Company’s 
shares are listed on a foreign regulated market, notices of general shareholders’ meetings shall also comply 
with the requirements (including as to content and publicity) and follow the customary practices of such 
regulated market. 
Pursuant to the Company’s articles of association, for as long as the shares or other securities of the 
Company are listed on a regulated market within the EU (as they currently are), and unless otherwise 
provided by applicable law, only shareholders holding shares as of midnight, central European time, on the 
day that is fourteen days prior to the day of any given general shareholders’ meeting can attend and vote at 
such meeting. The board of directors may determine other conditions that must be satisfied by shareholders 
in order to participate in a general shareholders’ meeting in person or by proxy, including with respect to 
deadlines for submitting supporting documentation to or for the Company. 
No attendance quorum is required at ordinary general shareholders’ meetings, and resolutions may be 
adopted by a simple majority of the votes validly cast, irrespective of the number of shares present or 
represented. Unless otherwise provided by applicable law, an extraordinary general shareholders’ meeting 
may not validly deliberate on proposed amendments to the Company’s articles of association unless a 
quorum of at least half of the share capital is represented at the meeting. If a quorum is not reached at the 
first extraordinary shareholders’ meeting, a second extraordinary shareholders’ meeting may be convened in 
accordance with the Company’s articles of association and applicable law, and such second extraordinary 
general shareholders’ meeting shall validly deliberate regardless of the number of shares represented. In both 
cases, the Luxembourg Company Law and the Company’s articles of association require that any resolution 
of an extraordinary general shareholders’ meeting as to amendments to the Company’s articles of association 
be adopted by a two-thirds majority of the votes validly cast at the meeting. If a proposed resolution consists 
of changing the Company’s nationality or of increasing the shareholders’ commitments, the unanimous 
consent of all shareholders is required. 
Cumulative voting is not permitted. The Company’s articles of association do not provide for staggered terms 
and directors are elected for a maximum of one year but may be reappointed or removed at any time, with or 
without cause, by the general shareholders’ meeting, by resolution passed by a simple majority vote of the 
shares validly cast at the meeting. In the case of a vacancy occurring in the board of directors, the remaining 
directors shall have the right to temporarily fill such vacancy with a temporary director appointed by 
resolution adopted with the affirmative vote of a majority of the remaining directors; provided that the next 
general shareholder’s meeting shall be called upon to ratify such appointment. The term of any such 
temporary director elected to fill a vacancy shall expire at the end of the term of office of the replaced 
director. 
The next annual general meeting of shareholders that will consider, among other matters, our consolidated 
financial statements and annual accounts included in this annual report, is scheduled to be held on Tuesday, 
May 6, 2025, at 10:00 (Central European Time) at the Company’s registered office in Luxembourg. An 
extraordinary general meeting of shareholders is scheduled to be held on the same date, immediately after 
the adjournment of the annual general meeting of shareholders to decide on (i) the cancellation of 
90,762,598 shares held in treasury by the Company acquired throughout the second, third and fourth 
tranches of the first share buyback program and throughout the follow-on share buyback program and, 
consequently, to approve a reduction of the Company’s issued share capital for $90,762,598 so as to bring 
the issued share capital from $1,162,757,528 to $1,071,994,930, represented by 1,071,994,930 shares with 
a nominal value of $1,00 each; (ii) the renewal for a five-year period of the authorization granted to its board 
of directors to issue shares within the limits of the authorized share capital without shareholder approval, and 
(iii) the approval of the corresponding amendment of article 5 “Share Capital” of the Company’s articles of 
association to reflect such resolutions.  
 

Annual Report 2024 
89 
The articles of association provide that annual general shareholders’ meetings shall meet in Luxembourg 
within six months from the end of the previous financial year at the date, place and hour indicated in the 
convening notice. The rights of the shareholders attending the meetings are governed by Shareholders’ 
Rights Law. 
Holders of shares deposited in fungible securities accounts have the same rights and obligations as holders of 
shares recorded in the Company’s share register. However, in order to be able to participate in and vote at 
shareholders’ meetings of the Company, the former must submit, prior to the relevant meetings, reasonably 
satisfactory evidence to the Company as to the number of shares held on the applicable record date for such 
meetings. For as long as the shares or the other securities of the Company are listed on a regulated market 
within the EU, participation in a shareholders’ general meeting shall inter alia be subject to the relevant 
shareholder holding shares of the Company on the fourteenth day midnight Central European Time prior to 
the meeting (unless otherwise provided for by applicable law). 
Holders of ADSs only have those rights that are expressly granted to them in the deposit agreement. See 
“Risk Factors – Risks Relating to shares and ADSs – Holders of ADSs may not be able to exercise, or may 
encounter difficulties in the exercise of, certain rights afforded to shareholders”. ADS holders may not attend 
or directly exercise voting rights in shareholder’ meetings, but holders of record of our ADSs as of the 
relevant ADS holders’ record date set for any given general shareholders’ meeting are entitled to instruct the 
Depositary as to the exercise of the voting rights in respect of the shares underlying such holder’s ADSs at 
such meeting. Holders of ADSs maintaining non-certificated positions must follow voting instructions given 
by their broker or custodian bank. 
The notices convening the annual general meeting of shareholders and an extraordinary general meeting of 
shareholders scheduled to be held on May 6, 2025, the Shareholder Meeting Brochure and Proxy Statement 
for the meetings, describing the procedures for attending and voting at the meetings; as well as the material 
required to be submitted to shareholders in connection with the meetings will be available on the Company’s 
website at https://ir.tenaris.com/investor-relations in accordance with applicable rules and regulations, 
and will be timely filed by the Company with the SEC on a report on Form 6-K. Information contained in or 
otherwise accessible through our Internet website is not a part of this annual report. 
Management 
Management of the Company is vested in a board of directors. For more information on the Company’s 
board of directors, audit committee, senior management, and auditors, see “Information on the Company - 
Directors, Senior Management and Employees”. 
Access to Corporate Records 
Luxembourg law and the Company’s articles of association do not generally provide for shareholder access to 
corporate records. Shareholders may inspect the annual accounts and auditors’ reports at our registered 
office during the fifteen-day period prior to a general shareholders’ meeting. 
Appraisal Rights 
In the event the Company’s shareholders approve: 
• 
the delisting of the shares from all stock exchanges where the shares are listed at that time; 
• 
a merger in which the Company is not the surviving entity (unless the shares or other equity securities 
of such entity are listed on the New York or London stock exchanges); 
• 
a sale, lease, exchange or other disposition of all or substantially all of the Company’s assets; 
• 
an amendment of our articles of association that has the effect of materially changing the Company’s 
corporate purpose; 
• 
the relocation of the Company’s domicile outside of the Grand Duchy of Luxembourg; or 
• 
amendments to the Company’s articles of association that restrict the rights of the Company’s 
shareholders.  
 

Annual Report 2024 
90 
Dissenting or absent shareholders have the right to have their shares repurchased by the Company at (i) the 
average market value of the shares over the 90 calendar days preceding the applicable shareholders’ meeting 
or (ii) in the event that the shares are not traded on a regulated market, the amount that results from 
applying the proportion of the Company’s equity that the shares being sold represent over the Company’s 
net worth as of the date of the applicable shareholders’ meeting. 
Dissenting or absent shareholders must present their claim within one month following the date of the 
shareholders’ meeting and supply the Company with evidence of their shareholding at the time of such 
meeting. The Company must (to the extent permitted by applicable laws and regulations and in compliance 
therewith) repurchase its shares within six months following the date of the shareholders’ meeting. 
If delisting from one or more, but not all, of the stock exchanges where the shares are listed is approved in 
the shareholders’ meeting, only dissenting or absent shareholders with shares held through participants in 
the local clearing system for that market or markets can exercise this appraisal right if: 
• 
they held the shares as of the date of the announcement by the Company of its intention to delist or 
as of the date of publication of the first convening notice for the general shareholders’ meeting that 
approved the delisting; and 
• 
they present their claim within one month following the date of the general shareholders’ meeting and 
supply evidence of their shareholding as of the date of the Company’s announcement or the 
publication of the first convening notice to the meeting. 
In the event a shareholder exercises its appraisal rights, applicable Luxembourg law provisions shall apply. 
Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights 
afforded to shareholders, including appraisal rights. See “Risk Factors – Risks Relating to shares and ADSs – 
Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights 
afforded to shareholders”. 
Distribution of Assets on Winding-Up 
In the event of the Company’s liquidation, dissolution or winding-up, the net assets remaining after allowing 
for the payment of all debts, charges and expenses will be paid out to the holders of the shares in proportion 
to their respective holdings. 
Transferability and Form 
The Company’s articles of association do not contain any redemption or sinking fund provisions, nor do they 
impose any restrictions on the transfer of shares. The shares are issuable in registered form only. 
The ownership of registered shares is evidenced by the inscription of the name of the shareholder, the 
number of shares held by such shareholders and the amount paid on each share in the Company’s share 
register. In addition, the Company’s shares may be held through fungible securities accounts with financial 
institutions or other professional depositaries. 
Shares held through fungible securities accounts may be transferred in accordance with customary 
procedures for the transfer of securities in book-entry form. Shares that are not held through fungible 
securities accounts may be transferred by a written statement of transfer signed by both the transferor and 
the transferee or their respective duly appointed attorney-in-fact and recorded in the Company’s share 
register. The transfer of shares may also be made in accordance with the provisions of Article 1690 of the 
Luxembourg Civil Code. As evidence of the transfer of registered shares, the Company may also accept any 
correspondence or other documents evidencing the agreement between transferor and transferee as to the 
transfer of registered shares.

Repurchase of Company shares  
 
The Company may repurchase its own shares in the cases and subject to the conditions set by the 
Luxembourg Company Law and, in the case of acquisitions of shares or ADSs made through a stock 
exchange in which shares or ADSs are traded, with any applicable laws and regulations of such market. 
Please see “Legal and Financial Information - Purchases of Equity Securities by the Company and Affiliated 
Purchasers” for further information on the authorization granted on June 2, 2020, by the annual general 
meeting of shareholders to the Company or its subsidiaries to repurchase shares of the Company, including 
shares represented by ADSs, and repurchase of Company shares under share buyback programs. 
Limitation on Securities Ownership 
There are no limitations currently imposed by Luxembourg law or the articles of association on the rights of 
the Company’s non-resident or foreign shareholders to hold or vote the Company’s shares. 
Change in Control 
None of our outstanding securities has any special control rights. The Company’s articles of association do 
not contain any provision that would have the effect of delaying, deferring or preventing a change in control 
of the Company and that would operate only with respect to a merger, acquisition or corporate restructuring 
involving the Company or any of its subsidiaries. In addition, the Company does not know of any significant 
agreements or other arrangements to which the Company is a party and which take effect, alter or terminate 
in the event of a change of control of the Company. There are no agreements between the Company and 
members of its board of directors or employees providing for compensation if they resign or are made 
redundant without reason, or if their employment ceases following a change in control of the Company. 
There are no rights associated with the Company’s shares other than those described above. 
Ownership Disclosure 
The Company’s articles of association do not contain any provision requiring disclosure of share ownership. 
However, under the Luxembourg Transparency Law investors in the Company’s securities should notify the 
Company and the Luxembourg securities commission on an ongoing basis whenever the proportion of voting 
rights held or controlled by any such investor reaches, exceeds or falls below any of the following thresholds: 
5%, 10%, 15%, 20%, 25%, 33.33%, 50% and 66.66%. Failure to notify the Company and the 
Luxembourg securities commission of the reaching or crossing of any such thresholds may result in the 
suspension of the voting rights attaching to the shares exceeding the threshold which would have had to be 
notified.

Summary of differences with NYSE standards  
 
As a Luxembourg company listed on the NYSE, the Bolsa Mexicana de Valores, S.A.B. de C.V. (the Mexican 
Stock Exchange), and the Borsa Italiana S.p.A. (the Italian Stock Exchange), the Company is required to 
comply with some, but not all, of the corporate governance standards of these exchanges. The Company, 
however, believes that its corporate governance practices meet, in all material respects, the corporate 
governance standards that are generally required for controlled companies by all of the exchanges on which 
the Company’s securities trade. 
The following is a summary of the significant ways that the Company’s corporate governance practices differ 
from the corporate governance standards required for foreign controlled companies by the NYSE. The 
Company’s corporate governance practices may differ in non-material ways from certain other standards 
required by the NYSE that are not detailed here. 
Non-management directors’ meetings 
Under NYSE standards, non-management directors must meet at regularly scheduled executive sessions 
without management present and, if such group includes directors who are not independent, a meeting 
should be scheduled once per year including only independent directors. Neither Luxembourg law nor the 
Company’s articles of association require the holding of such meetings and the Company does not have a set 
policy for these meetings. For additional information on board meetings, see “Information on the Company - 
Directors, Senior Management and Employees – Directors and Senior Management”.  
In addition, NYSE-listed companies are required to provide a method for interested parties to communicate 
directly with non-management directors as a group. While the Company does not have such a method, it has 
set up a compliance line for investors and other interested parties to communicate their concerns directly to 
the members of our audit committee, all of whom are non-management, independent directors. 
Audit committee composition 
Under NYSE standards, listed U.S. companies are required to have an audit committee composed of 
independent directors that satisfy the requirements of Rule 10A-3 promulgated under the Exchange Act. 
Pursuant to the Company’s articles of association, as supplemented by the audit committee’s charter, for as 
long as the Company’s shares are listed on at least one regulated market, the Company must have an audit 
committee composed of at least three members, the majority of whom must qualify as independent directors 
(as defined in the Company’s articles of association), provided, however, that the composition and 
membership of the audit committee shall satisfy such requirements as are applicable to, and mandatory for, 
audit committees of issuers such as the Company under any law, rule or regulation applicable to the 
Company (including, without limitation, the applicable laws, rules and regulations of such regulated market 
or markets). The Company’s audit committee, which currently consists of three members, complies with such 
requirements. In accordance with NYSE standards, the Company has an audit committee entirely composed 
of independent directors for purposes of the Exchange Act Rule 10A-3(b)(1). For more information on the 
Company’s audit committee see “Information on the Company - Directors, Senior Management and 
Employees - Board Practices”. 
Under NYSE standards, all audit committee members of listed U.S. companies are required to be financially 
literate or must acquire such financial knowledge within a reasonable period and at least one of its members 
shall have experience in accounting or financial administration. In addition, if a member of the audit 
committee is simultaneously a member of the audit committee of more than three public companies, and the 
listed company does not limit the number of audit committees on which its members may serve, then in each 
case the board must determine whether the simultaneous service would prevent such member from 
effectively serving on the listed company’s audit committee and shall publicly disclose its decision. 
Luxembourg law provisions on audit committee membership require only that at least one member of the 
audit committee have competence in accounting or auditing matters. The board of directors of the Company 
has determined that Ms. Tiuba, the committee’s chairperson, qualifies as “audit committee financial expert” 
under applicable SEC rules and has competence in accounting or auditing matters, as required by applicable 
Luxembourg law. In addition, the membership of the audit committee as a whole has sufficient relevant 
knowledge of the business and financial experience to properly discharge its functions. The audit committee 
has the authority, from time to time and as it deems necessary, to engage persons that meet all of the 
attributes of a financial expert as consultants.  
 

Annual Report 2024

Standards for evaluating director independence 
Under NYSE standards, the board is required, on a case-by-case basis, to express an opinion with regard to 
the independence or lack of independence of each individual director. Neither Luxembourg law nor the 
Company’s articles of association requires that the board of directors express such an opinion. In addition, 
the definition of “independent” under the NYSE rules differs in some non-material respects from the 
definition contained in the Company’s articles of association. For more information on the Company’s 
independent directors and the definition of “independent” under the Company’s articles of association see 
“Information on the Company - Directors, Senior Management and Employees - Directors and Senior 
Management” and “Information on the Company - Directors, Senior Management and Employees - Board 
Practices”. 
Audit committee responsibilities 
Pursuant to the Company’s articles of association, the audit committee shall assist the board of directors in 
fulfilling its oversight responsibilities relating to the integrity of its consolidated financial statements, the 
effectiveness of its systems of internal control, risk management and internal audit over financial reporting 
and the independence and performance of the external auditors. The audit committee is required to review 
and, where applicable, approve material transactions between the Company or its subsidiaries and related 
parties and also perform the other duties entrusted to it by the board. The NYSE requires certain matters to 
be set forth in the audit committee charter of U.S. listed companies.  
The Company’s audit committee charter provides for many of the responsibilities that are expected from such 
bodies under the NYSE standard and in accordance with applicable Luxembourg law, including the Audit 
Reform Law; however, due to the Company’s equity structure and holding company nature, the charter does 
not contain all such responsibilities, including provisions related to procedures for the receipt and treatment 
of complaints, other than complaints regarding accounting, internal accounting controls and audit matters, 
(although the Company has established such procedures); funding for payment of administrative expenses 
and compensation to advisors (although the audit committee has the authority to engage outside advisors); 
setting hiring policies for employees or former employees of external auditors; and an annual performance 
evaluation of the audit committee. For more information on the Company’s audit committee see 
“Information on the Company - Directors, Senior Management and Employees - Board Practices”. 
Standards for approval of related-party transactions 
The Company is subject to Luxembourg laws governing approval and disclosure of material related party 
transactions, including the Shareholders’ Rights Law; and the Company’s articles of association and the Audit 
Committee charter require the Audit Committee to review material transactions with related parties to 
determine whether their terms are consistent with the interests of the Company and its shareholders and 
with market conditions. In addition, NYSE requires all NYSE-listed companies’ audit committees (or another 
independent body of the board of directors) to conduct a reasonable prior review and oversight of all related 
party transactions for potential conflicts of interest and to prohibit such a transaction if it determines it to be 
inconsistent with the interests of the company and its shareholders. The rule defines the term “related party 
transaction” by reference to the disclosure requirements for annual reports under the Exchange Act. The 
materiality threshold applicable to foreign private issuers differs to the one applicable to U.S companies. For 
further details on the approval process for related party transactions, see “Information on the Company - 
Directors, Senior Management and Employees – Board Practices”. 
Shareholder voting on equity compensation plans 
Under NYSE standards, shareholders must be given the opportunity to vote on equity-compensation plans 
and material revisions thereto, except for employment inducement awards, certain grants, plans and 
amendments in the context of mergers and acquisitions, and certain specific types of plans. The Company 
does not currently offer equity-based compensation to its directors, senior management or employees, and 
therefore does not have a policy on this matter. For more information on directors’ compensation see 
“Information on the Company - Directors, Senior Management and Employees - Compensation”.  

Annual Report 2024

The Shareholders’ Rights Law requires the Company to adopt a Compensation Policy setting forth the 
principles and guidelines for purposes of determining the compensation payable to the members of the 
Company’s board of directors and the managing director or chief executive officer. Such Compensation 
Policy must be submitted to the non-binding vote of the shareholders. In addition, the Shareholders’ Rights 
Law provides that the Company must prepare an annual report describing the compensation paid to directors 
and the chief executive officer for the performance of their duties and submit such report to the shareholders 
for approval. The Compensation Policy and Compensation Report must be available on the Company’s 
website. For more information on the Compensation Policy and the 2024 Compensation Report see 
“Information on the Company - Directors, Senior Management and Employees - Compensation”. 
Disclosure of corporate governance guidelines 
NYSE-listed companies must adopt and disclose corporate governance guidelines. Neither Luxembourg law 
nor the Company’s articles of association require the adoption or disclosure of corporate governance 
guidelines. The Company’s board of directors follows corporate governance guidelines consistent with its 
equity structure and holding company nature, but the Company has not codified them and therefore does 
not disclose them on its website. 
Code of business conduct and ethics 
Under NYSE standards, listed companies must adopt and disclose a code of business conduct and ethics for 
directors, officers and employees, and promptly disclose any waivers of the code for directors or executive 
officers. Neither Luxembourg law nor the Company’s articles of association require the adoption or disclosure 
of such a code of conduct. The Company, however, has adopted a code of conduct that applies to all 
directors, officers and employees that is posted on its website and which complies with the NYSE’s 
requirements, except that it does not require the disclosure of waivers of the code for directors and officers. 
In addition, it has adopted a supplementary code of ethics for senior financial officers, which is also posted 
on our website. See “Sustainability Statement – Sustainability in Tenaris – Policies and Procedures”. 
Chief Executive Officer certification 
A chief executive officer of a U.S. company listed on the NYSE must annually certify that he or she is not 
aware of any violation by the company of NYSE corporate governance standards. In accordance with NYSE 
rules applicable to foreign private issuers, the Company’s chief executive officer is not required to provide the 
NYSE with this annual compliance certification. However, in accordance with NYSE rules applicable to all 
listed companies, the Company’s chief executive officer must promptly notify the NYSE in writing after any of 
our executive officers becomes aware of any noncompliance with any applicable provision of the NYSE’s 
corporate governance standards. In addition, the Company must submit an executed written affirmation 
annually and an interim written affirmation upon the occurrence of any of the events listed in the foreign 
private issuer interim written affirmation form by the NYSE.

Board of Directors 
Management of the Company is vested in a board of directors with the broadest power to act on behalf of 
the Company and accomplish or authorize all acts and transactions of management and disposal that are 
within its corporate purpose and not specifically reserved in the articles of association or by applicable law to 
the general shareholders’ meeting. The Company’s articles of association provide for a board of directors 
consisting of a minimum of three and a maximum of fifteen directors; however, for as long as the Company’s 
shares are listed on at least one regulated market, the minimum number of directors must be five. The 
Company’s current board of directors is composed of eleven directors. 
 
The board of directors is required to meet as often as required by the interests of the Company and at least 
four times per year. Board of directors’ meetings can be validly held by means of teleconference call, video 
conference or any other means genuinely allowing for the participation, interaction and intercommunication 
of the attending directors. Written decisions, signed by all the directors, are proper and valid as though they 
had been taken at a meeting of the board of directors duly convened and held. In 2024, the Company’s 
board of directors met six times and adopted two unanimous written resolutions. A majority of the members 
of the board of directors in office present or represented at the board of directors’ meeting constitutes a 
quorum, and resolutions may be adopted by the vote of a majority of the directors present or represented. In 
case of a tie, the chairman is entitled to cast the deciding vote. 
 
Directors are elected at the annual ordinary general shareholders’ meeting to serve one-year renewable 
terms, as determined by the general shareholders’ meeting. The general shareholders’ meeting also 
determines the number of directors that will constitute the board and their compensation. The general 
shareholders’ meeting may dismiss all or any one member of the board of directors at any time, with or 
without cause, by resolution passed by a simple majority vote, irrespective of the number of shares 
represented at the meeting. 
The Company’s articles of association provide that the board of directors of the Company may within the 
limits of applicable law, (a) delegate to one or more persons, whether or not members of the board of 
directors, the powers necessary to carry out its decisions and to provide day-to-day management (except for 
approval of material transactions with related parties, which may not be delegated and shall be approved by 
the board of directors prior opinion of the audit committee), (b) confer to one or more persons, whether or 
not members of the board of directors the powers deemed to be appropriate for the general, technical, 
administrative and commercial management of the Company, (c) constitute an audit committee formed by 
directors, determining its function and authority, and (d) constitute any other committee, whose members 
may or may not be members of the board of directors and determine their functions and authority.  
On April 30, 2024, the board of directors appointed Tenaris’s chief executive officer as administrateur 
délégué and delegated to him the power to manage the Company’s affairs within the ordinary course of 
business, to the full extent permitted by Luxembourg law, to direct and supervise the business activities of the 
Company’s subsidiaries and to represent the Company in relation to such matters. 
On a quarterly basis, the Company’s board of directors meets to review the performance of the Company 
and approve quarterly financial statements. Sustainability metrics, including health and safety, environmental, 
CO2eq emissions evolution and decarbonization strategy progress, are integrated and regularly discussed. As 
part of the board’s review process, internal and external experts on sustainability topics, such as environment, 
health and safety and cybersecurity, are invited to participate in specific board meetings to discuss relevant 
information concerning financial or sustainability matters.

Directors’ Liability 
Each director must act in the interest of the Company, and in accordance with applicable laws, regulations, 
and the Company’s articles of association. Directors are also bound by a general duty of care owed to the 
Company. 
Under the Luxembourg law of August 10, 1915, on commercial companies, as amended (the “Luxembourg 
Company Law”), directors may be liable to the Company in accordance with general law for the execution of 
their mandate and for any misconduct in the management of the Company’s affairs. Directors are jointly and 
severally liable towards either the Company or any third parties from damages resulting from the violation of 
the Luxembourg Company Law or the Company’s articles of association. Directors shall be discharged from 
such liability in the case of a violation to which they were not a party provided no misconduct is attributable 
to them and such violation has been reported to the first general meeting of shareholders after they have 
acquired knowledge thereof. 
Causes of action against directors for damages may be initiated by the Company upon a resolution of the 
general shareholders’ meeting passed by a simple majority vote, irrespective of the number of shares 
represented at the meeting. Causes of action against directors who misappropriate corporate assets or 
commit a breach of trust may be brought by any shareholder for personal losses different from those of the 
Company.  
 
An action may also be brought against the directors on behalf of the Company by shareholders who, at the 
general meeting deciding to discharge such directors or members, owned voting securities representing at 
least ten percent of the votes attaching to all such securities.  
 

Annual Report 2024 
99 
It is customary in Luxembourg that the shareholders expressly discharge the members of the board of 
directors from any liability arising out of or in connection with the exercise of their mandate when approving 
the annual accounts of the Company at the annual general shareholders meeting. However, any such 
discharge will not release the directors from liability for any damage caused by unrevealed acts of 
mismanagement or unrevealed breaches of the Luxembourg Company Law or the Company’s articles of 
association, nor will it release directors from liability for any personal loss of the shareholders independent 
and separate from losses suffered by the Company due to a breach either revealed or unrevealed of the 
Luxembourg Company Law or the Company’s articles of association. 
Under Luxembourg law, unless the decision of the board of directors relates to ordinary business entered into 
under normal conditions, any director having a direct or indirect financial interest conflicting with that of the 
Company in a transaction which has to be considered by the board of directors, must advise the board 
thereof and cause a record of her/his statement to be included in the minutes of the meeting and may not 
take part in the deliberations. At the next following general meeting, before any other resolution is put to 
vote, a special report must be made on any transactions in which any of the directors may have had an 
interest conflicting with that of the Company. 
 

Annual Report 2024

Auditors 
The Company’s articles of association require the appointment of an independent audit firm in accordance 
with applicable law. The primary responsibility of the external auditor is to audit the Company’s annual 
accounts and consolidated financial statements and to submit a report on the accounts to shareholders at the 
annual shareholders’ meeting. In accordance with applicable law, statutory auditors are chosen from among 
the members of the Luxembourg Institute of Independent Auditors (Institut des réviseurs d’entreprises). In 
addition, the sustainability statement is subject to a limited assurance review by an independent auditor. 
 
Auditors are appointed by the general shareholders’ meeting, upon recommendation from the Company’s 
audit committee, through a resolution passed by a simple majority vote, irrespective of the number of shares 
represented at the meeting, to serve one-year renewable terms. Auditors may be dismissed for reasonable 
cause by the general shareholders’ meeting at any time. Luxembourg law does not allow directors to serve 
concurrently as external auditors. As part of their duties, auditors report directly to the audit committee. 
 
Pursuant to its charter, the Company’s audit committee is responsible for, among other things, the oversight 
of the independence and performance of the Company’s external auditors. The audit committee is also 
responsible to consider and make recommendations to the board of directors, to be put to shareholders for 
approval at the annual general meeting of shareholders, regarding the appointment, re-appointment or 
removal of the Company’s external auditors. In addition, the audit committee is responsible for reviewing the 
appropriateness and provision of permitted non-audit fees and to review and approve any fees (whether for 
audit, audit-related and non-audit services) payable to the Company’s external auditors. On an annual basis, 
in the performance of its functions, the audit committee considers the appointment of the Company’s 
external auditors and reviews, together with management and the external auditor, the audit plan, audit 
related services and other non-audit services. The audit committee requests the board of directors to submit 
the audit committee’s recommendation for the appointment of the Company’s external auditor for each 
fiscal year and the payment of applicable fees for final approval by the general shareholders’ meeting. The 
general shareholders’ meeting regularly approves audit fees and authorizes the audit committee to approve 
any increase or reallocation of such audit fees as may be necessary, appropriate or desirable under the 
circumstances. No services outside the scope of the audit committee’s approval can be undertaken by the 
external auditor. 
Following the completion of a tender process for the selection of a replacement audit firm for the year 2024, 
as required under applicable EU and Luxembourg mandatory auditor rotation rules, the Company’s board of 
directors, based on the audit committee’s recommendation, recommended the annual general shareholders’ 
meeting to appoint Ernst & Young S.A. (“EY”) as the Company’s statutory auditors for the fiscal year ended 
December 31, 2024. The annual general shareholders meeting held on May 3, 2023, approved the 
appointment of EY as the Company’s statutory auditor for the fiscal year 2024 and the annual general 
shareholders meeting held on April 30, 2024, approved EY’s fees for the year 2024. For information on the 
appointment of external auditors for the year ending December 31, 2025, please refer to “Legal and 
Financial Information - Change in Registrant´s Certifying Accountant”. 
PricewaterhouseCoopers, Société coopérative (“PwC”) was engaged to carry out a limited assurance review 
of the non-financial information in the sustainability statement included in this annual report.

directors, provided, however, that the composition and membership of the audit committee shall satisfy such 
requirements as are applicable to, and mandatory for, audit committees of issuers such as the Company 
under any law, rule or regulation applicable to the Company (including, without limitation, the applicable 
laws, rules and regulations of such regulated market or markets). 
Under the Company’s articles of association, an independent director is a director who: 
•

Audit Committee’s composition - Financial Expert 
The audit committee of the Company’s board of directors currently consists of three members: Mr. Simon 
Ayat, Mr. Jaime José Serra Puche and Ms. Monica Tiuba, who were appointed to the audit committee by the 
Company’s board of directors on April 30, 2024. As of the date of this annual report, all members of the 
audit committee qualify as independent directors both for purposes of the Exchange Act Rule 10A-3(b)(1), 
and under the Company’s articles of association. 
The board of directors of the Company has determined that Ms. Tiuba, the committee’s chairperson, qualifies 
as “audit committee financial expert” under applicable SEC rules and has competence in accounting or 
auditing matters, as required by applicable Luxembourg law. In addition, the membership of the audit 
committee as a whole has sufficient relevant knowledge of the business and financial experience to properly 
discharge its functions. The audit committee has the authority, from time to time and as it deems necessary, 
to engage persons that meet all of the attributes of a financial expert as consultants. 
Audit Committee’s responsibilities 
The audit committee operates under a charter amended and restated by the board of directors on October 8, 
2021. The audit committee assists the board of directors in its oversight responsibilities relating to (i) the 
integrity of the Company’s financial statements; (ii) the effectiveness of the Company’s systems of internal 
control, risk management and internal audit over financial reporting; and (iii) the independence and 
performance of the Company’s external auditors. The audit committee also performs other duties entrusted 
to it by the Company’s board of directors or required to be performed by it under applicable laws and 
regulations. 
In addition, the audit committee is required to review and, where applicable, approve material transactions 
between the Company or its subsidiaries and related parties, as provided in the Company’s articles of 
association, or as may be required by any law, rule or regulation applicable to the Company, in order to 
determine whether their terms are consistent with the interests of the Company and all its shareholders and 
are consistent with market conditions or are otherwise fair to the Company and its subsidiaries. The 
Company has adopted a Related Party Transactions Policy and Procedure setting forth the revised, updated 
and consolidated guidelines and processes through which the Company identifies, approves and manages 
related party transactions, seeking to assure transparency and substantial and procedural fairness of such 

Annual Report 2024 
105 
transactions, as well as compliance with the provisions in the Company’s articles of association and the audit 
committee charter relating to transactions with related parties, Luxembourg rules relating to the approval and 
disclosure of material related party transactions, and Section 314.00 of the NYSE Listed Company Manual.  
 
Under the Company’s articles of association, as supplemented by the Related Party Transactions Policy and 
Procedure, a “related party” is any of the following persons: (i) any affiliate of the Company; (ii) any entity in 
which a controlling person owns a substantial interest or over which a controlling person can exercise 
significant influence; (iii) any unconsolidated entity in which the Company has significant influence; (iv) any 
entity or individual having significant influence over the Company, or a close family member of any such 
individual; (v) any individual or entity that is the beneficial owner of five percent (5%) or more of the shares 
of the Company, including through the ownership of any securities representing shares of the Company; (vi) 
any director or executive officer of any of the controlling persons, the Company or any of the subsidiaries, or 
a close family member of any such director or executive officer; (vii) any entity in which a substantial interest 
in the voting power is owned, directly or indirectly, by any person described in (iv), (v) or (vi) above or over 
which such a person is able to exercise significant influence; or (viii) any entity that has a member of key 
management in common with the Company or any of its subsidiaries (provided that key management 
personnel includes persons having authority and responsibility for planning, directing and controlling the 
activities of an entity, including directors and executive officers and close family members of any such 
individuals). 
 
With respect to the materiality threshold for review and approval of related party transactions, the 
Company’s articles of association, as supplemented by the audit committee’s charter and the Related Party 
Transactions Policy and Procedure, provide that the following related party transactions, which are qualified 
as “Level 1” related party transactions, are subject to review by the audit committee, which shall make a 
recommendation to the board of directors as to either reject or approve the proposed related party 
transaction: 
 
• 
any transaction between the Company or its subsidiaries with related parties (i) with an individual value 
equal to or greater than $10 million, or its equivalent in other currencies, or (ii) with an individual value 
lower than $10 million, or its equivalent in other currencies, when the aggregate sum reflected in the 
financial statements of the four fiscal quarters preceding the date of determination of any series of 
transactions for such lower value that can be deemed to be parts of a unique or single transaction (but 
excluding any transactions that were reviewed and approved by Company’s audit committee or board of 
directors, as applicable, or the independent members of the board of directors of any of its subsidiaries) 
exceeds 1.5% of the Company’s consolidated net sales made in the fiscal year preceding the year on 
which the determination is made; and 
 
• 
any corporate reorganization transaction (including a merger, spin-off or bulk transfer of a business) 
affecting the Company or any of its subsidiaries for the benefit of, or involving, a related party. 
 
In addition, any related party transaction that does not qualify as a “Level 1” related party transaction, but 
which has an individual value equal to or higher than $5 million (which is the value threshold determined by 
management to be material to the Company for disclosure purposes under “Related Parties Transactions” of 
this annual report), qualifies as a “Level 2” related party transaction and must be reviewed by the audit 
committee for purposes of making a determination as to whether any conflicts of interest exist and whether 
the proposed related party transaction is consistent with the interests of the Company and all shareholders, in 
order to either reject or approve the proposed transaction. Any related party transaction that is for less than 
such value qualifies as a “Level 3” related party transaction and is reviewed by the Company’s related-party 
transaction unit, the area within the Company responsible for centralizing and compiling the information 
relating to all related party transactions and performing the review, assessment and other procedures 
contemplated in the Related Party Transactions Policy and Procedure. 
 
The audit committee has the power (to the maximum extent permitted by applicable laws) to request that the 
Company or relevant subsidiary promptly provide all information necessary for the audit committee to assess 
the material transactions with related parties that it is required to review. In no event may any proposed 
related party transaction be entered into or otherwise be given effect unless it has been reviewed and 
approved in accordance with the Related Party Transactions Policy and Procedure. Any executed transaction 
that has not been duly reviewed and approved must be promptly submitted for review in accordance with 
applicable procedures and, if determined appropriate, must be ratified; if the transaction is not ratified, it 
must be modified to make it acceptable for ratification or it must otherwise be immediately discontinued or 
rescinded. 
 
 

Annual Report 2024

The audit committee has the authority to conduct any investigation appropriate to the fulfillment of its 
responsibilities and has direct access to the Company’s external auditors as well as anyone in the Company 
and, subject to applicable laws and regulations, its subsidiaries. In addition, the audit committee may engage, 
at the Company’s expense, independent counsel and other internal or external advisors to review, investigate 
or otherwise advise on, any matter as the committee may determine to be necessary to carry out its purposes 
and responsibilities. 
 
The audit committee is also in charge of the interpretation, implementation, control and enforcement of the 
Company’s Clawback Policy (the “Clawback Policy”), which sets forth the principles for the prompt recovery 
of erroneously awarded incentive-based compensation granted to certain officers of the Company in the 
event of a restatement of the Company’s financial statements. 
 
Risk Management 
The Company has established a management-level critical risk committee that assists the Company’s board of 
directors, the audit committee and the chief executive officer in connection with the monitoring, assessment 
and review of risks to which Tenaris is exposed and in the oversight of the risk management framework and 
processes, with a focus on critical risks (including accidents, cybersecurity, commercial execution, 
environmental, health and safety and regulatory risks), the development of mitigating actions, and the 
monitoring of action plans. The critical risk committee operates under a critical risk management revised 
charter approved by the board of directors on April 26, 2023, which sets forth the roles, composition and 
responsibilities of the critical risk committee. The critical risk committee assists the board of directors, the 
audit committee and the chief executive officer with the oversight of the risks to which Tenaris is exposed 
and monitors the risk management process, including risk mapping, mitigation and prevention, with a focus 
on critical risks. The critical risk committee periodically reports to the board of directors, the audit committee 
and the chief executive officer on its activities. 
 
Risks are identified and managed by management. Risk factors are classified according to the potential area 
impacted, the likelihood of their occurrence and the severity of any eventual impact. The critical risk 
committee primarily focuses on risks considered critical to Tenaris’s assets, operations, reputation or that have 
the potential to trigger significant liabilities. The critical risk committee facilitates the identification and 
assessment of critical risks, the adoption of mitigating actions and the monitoring of action plans. Critical 
risks are escalated through existing reporting lines and decisions are not dissociated from other management 
decisions. For the purpose of performing the double materiality assessment (“DMA”) in connection with the 
reporting of non-financial information, we have identified and assessed material topics in accordance with 
the requirements of the ESRS and found the topics identified as material to Tenaris were consistent and 
aligned with the risk map developed by the critical risk committee. For more information on DMA and results, 
refer to “Sustainability Statement - Double Materiality Assessment”.

SUSTAINABILITY STATEMENT 
 
Sustainability In Tenaris 
 
Tenaris is a leading global manufacturer and supplier of steel pipe products and related services for the 
world’s energy industry and other industrial applications. Our customers include most of the world’s leading 
oil and gas companies, and we operate an integrated network of steel pipe manufacturing, research, 
finishing and service facilities with industrial operations in the Americas, Europe, the Middle East, Asia and 
Africa. Although our operations focus on serving the oil and gas industry, we also supply pipes and tubular 
components for non-energy applications. We develop and supply products and services for low-carbon 
energy applications such as geothermal wells, waste-to-energy (bio-energy) power plants, hydrogen storage 
and transportation, and CCS.  
 
Through an integrated global network of R&D, manufacturing and service facilities, and a team of around 
26,000 people worldwide, we work with our customers to meet their needs in a timely manner, observing 
the highest levels of product performance and reliability. Our core values of safety, health, environment, 
quality and transparency guide our daily activity. They are clearly reflected in our Code of Conduct and our 
Quality, Health, Safety, and Environment (“QHSE”) Policy, and are embedded in all aspects of our business 
processes. This sustainability statement shows how these values translate into concrete actions and are 
reflected in our performance indicators. 
  
As a long-term project, Tenaris goes back over seven decades. Since we opened our first mill on the banks of 
the Paraná River in Campana, Argentina, in the early 1950s, our prime objective has been to grow together 
with the communities where we work and live. We are equally committed to providing our employees with a 
safe working environment and opportunities for professional development; to minimizing our environmental 
footprint and being a reliable partner for our customers. Tenaris is a signatory to the United Nations Global 
Compact, a commitment to translate the Ten Principles deriving from the Universal Declaration of Human 
Rights into daily business activity. Our Human Rights Policy is a pledge to conduct company operations 
commensurate with human rights principles.  
 
Although steel can be reused and recycled indefinitely, playing a key role in the development of society and 
improving quality of life, the steel industry is a significant source of carbon emissions worldwide. The industry 
has joined forces to promote transparent reporting and take action to reduce emissions, with Tenaris playing 
a leading role in these initiatives. For the past seven years, worldsteel has named Tenaris a Sustainability 
Champion for “leading the way in creating a truly sustainable steel industry and society.”  
 
We have integrated climate change risks into our governance and business strategy and set a medium-term 
target to reduce the carbon intensity of our activities by 2030 as part of our longer-term carbon neutrality 
objective. As a leader in our industrial sector, we aim to be at the forefront of sector carbon performance and 
initiatives to reduce emissions. A significant part of our investments goes to improving safety, reducing the 
environmental impact of our operations, and advancing educational standards and opportunities in our 
communities, considered critical to our long-term sustainability.  
 
Our Health, Safety and Environment, and Quality Management systems are designed according to the latest 
versions of the ISO 14001, ISO 45001 and ISO 9001 standards. Today, 83% of our production sites are 
working under management systems certified according to these standards.

Basis for Presentation 
This sustainability statement includes the non-financial information required to be disclosed in accordance 
with applicable Luxembourg law8 and the reporting requirements regarding environmentally sustainable 
economic activities (EU Taxonomy)9. Given the differences in the applicable legal and analytical frameworks 
underlying this sustainability statement and the remainder of this annual report, we note that our approach 
to disclosures included in this sustainability statement (including related annexes) differs from our approach 
to the disclosures included in other sections of this annual report, as well as other disclosures we include in 
financial reports (including other filings with the SEC). While this sustainability statement includes information 
about sustainability topics that we believe may be important to Tenaris and our stakeholders under 
Luxembourg law and the EU Taxonomy, any importance attributed to such topics or related disclosures, or 
their inclusion in this sustainability report, should not be deemed to mean that such information necessarily 
rises to the level of materiality applied in our financial reporting, including for purposes of complying with 
U.S. securities laws and regulations or other reporting frameworks, even when we use the word "material" 
or "materiality" in connection with sustainability-related topics in this document. Consistent with applicable 
Luxembourg and EU law, this sustainability statement is intended to provide information from a different 
perspective, and in some cases in greater detail, than is required to be included in our filings with the SEC 
under U.S. securities laws and regulations. This sustainability statement is part of the 2024 annual report, 
which was approved by the Company’s board of directors on April 1, 2025. 
 
While the EU CSRD has not been transposed into national law by the Grand Duchy of Luxembourg and, 
therefore, the Company is not subject to CSRD reporting requirements, this sustainability statement has been

Double Materiality Assessment 
 
Identifying and Assessing Material Impacts, Risks and Opportunities 
 
In 2024, Tenaris performed a Double Materiality Assessment (“DMA”) to identify and assess the material ESG 
topics and information to be reported in accordance with the ESRS. The findings of the DMA are consistent 
and aligned with the results of the Company’s risk mapping assessment separately carried out by the 
Company’s critical risk committee and the sustainability topics that the Company was already reporting. We 
performed the DMA following a five-step methodology.  
 
Identification of ESG topics and value chain mapping 
 
We used a combination of internal and external sources which may reasonably be considered to be relevant 
inasmuch as they reflect our economic, environmental and social impacts, or influence the decisions of our 
stakeholders. We used peer analysis and prior materiality results based on different guidelines, including, 
worldsteel, UN Global Compact, Global Reporting Initiative (“GRI”), Sustainable Accounting Standards Board 
(“SASB”), and Task Force on Climate-related Financial Disclosures (“TCFD”), to ensure comprehensive 
coverage.  
 
Topics were mapped across Tenaris's value chain and validated with internal stakeholders, ensuring all 
activities, relationships, and geographies were included.  
 
Impact Materiality 
 
The impact materiality assessment consists of identifying and evaluating actual, potential, positive and 
negative impacts within each ESRS topic, based on their time horizon, severity, and likelihood of occurrence 
in the case of potential impacts, as guided by the European Financial Reporting Advisory Group (“EFRAG”) 
methodology.  
 
We evaluated the severity of impacts: for positive impacts, scale and scope were assessed, while for negative 
impacts, scale, scope, and remediability were considered. Each category was rated on a scale of 1 (least 
severe) to 5 (most severe). For potential impacts, likelihood was also assessed, using a scale from 1 (unlikely) 
to 5 (certain). 
 
Financial Materiality 
 
The financial materiality assessment consists in assessing risks and opportunities in terms of time horizon, 
magnitude and likelihood of occurrence.  
 
Risks and opportunities were identified for each impact determined during the impact materiality assessment. 
Magnitude was assessed: for risks, this referred to the scale of damage or disruption (e.g., financial loss), 
while for opportunities, it reflected the scale of potential benefits (e.g., financial gain). Finally, the likelihood 
of occurrence was rated on a scale from 1 (unlikely) to 5 (certain). 
 
Consolidation of Double Materiality Assessment results 
 
The fourth step consisted in consolidating the results through the definition of a materiality threshold for 
each impact, risk and opportunity.  
 
Actual impacts were considered material when the average of the severity rating, i.e., scale, scope or 
irremediability (for negative impacts only) exceeded a certain threshold. 
 
For potential impacts, both severity and likelihood were considered. Severity was calculated as the average of: 
scale, scope and remediability.  
 
For risks and opportunities both magnitude and likelihood were considered.  
 
 

Annual Report 2024 
122 
Stakeholder Engagement 
 
We engaged with internal and external stakeholders to assess the importance of ESG topics through 
interviews and review the DMA outcome. This process ensured alignment between the results of the 
assessment and the ESG topics identified as most significant by such stakeholders.  
 
Stakeholder engagement is an important aspect of the DMA, as relevant stakeholders can help assess and 
validate the list of material topics.  
 
Similarly, internal engagement with the undertaking’s business functions and employees also helps to assess 
and validate impacts, risks and opportunities.  
 
We use formal and informal methods to obtain feedback about material sustainability topics from our 
employees, customers, suppliers, communities, investors and other key stakeholders. 
 
A key step towards understanding the context is to identify those stakeholders who are affected, or likely to 
be affected by our operations. We have identified key affected stakeholders, together with a description of 
the different ways in which we engage with them. 
 
The activities listed in the table detail the principal ways in which we obtain feedback from stakeholders on 
issues related to sustainability. 
 
Other sources include the Company’s Compliance Line, available 24/7, where stakeholders can report any 
alleged breach of the Company's Code of Conduct or its principles, such as acts of corruption, fraud, theft, 
and abuse or discrimination in the workplace. See “Sustainability Statement – Governance - Business 
Conduct” for more information on the Company’s Compliance Line.

Objectives 
 
• 
Achieve 30% reduction in the CO2-eq intensity of our operations by 2030 from 2018 levels and 
become carbon neutral as soon as technology and market conditions allow. 
• 
Implement CO2 reduction opportunities along our value chain. 
• 
Minimize particulate and other emissions at our sites. 
•

Key actions 
 
• 
Investments and actions for reducing environmental and carbon footprint. 
• 
Improve material efficiency and water management. 
• 
Engage with suppliers and customers to identify CO2eq reduction opportunities along our value 
chain. 
 
Steel is an essential material for our daily lives, used everywhere and for a variety of products, yet steelmaking 
is a highly energy-intensive process and produces significant quantities of different emissions, including 
carbon dioxide. The steel industry faces many environmental challenges and climate change is one of the 
most critical. 
The physical, social and financial risks of climate change, and the global challenge of lowering greenhouse 
gas emissions, are pushing the steel industry to find new solutions for reducing its carbon footprint and 
transitioning to a low carbon economy.  
New technologies and practices bring both economic and environmental benefits, from recycling materials as 
part of the circular economy, to harnessing cleaner energy.  
Greater energy and material efficiency, as well as increased waste recycling and the use of renewables in 
addition to innovative technologies like hydrogen, are best achieved through continued industry 
collaboration. These alternatives, however, are not equally successful or feasible in all facilities due to 
significant regional and site differences. 
As an industry leader, Tenaris believes that its responsibility to reduce the environmental impact of its activity 
is also an opportunity to embrace innovation and technological development and engage its partners in the 
value chain to contribute to a cleaner future. 
 
 

Annual Report 2024

Environmental Management System 
We have implemented an Environmental Management System (“EMS”) according to ISO 14001, integrated 
with the Health and Safety Management System to ensure a holistic approach to the management of all our 
material impacts, risks, and opportunities related to climate change mitigation and adaptation, air pollution, 
water management, chemicals, circularity and biodiversity management.  
The EMS is based upon our QHSE Policy through which Tenaris aims to achieve the highest standards of 
QHSE, incorporating the principles of sustainable development throughout its worldwide business. It is 
certified with a multisite certification, meaning that the system designed and implemented is the same for the 
whole company and, as such, has an audit system implemented that verifies not only local implementation 
and performance, but also corporate oversight to the system accuracy and performance. Tenaris 
communicates its policy throughout its organization, trains its employees in the appropriate use of its Quality, 
Health, Safety and Environmental management systems and engages them in the regular setting, measuring 
and revision of objectives.  
The EMS addresses all environmental aspects from the reduction of greenhouse gas emissions, energy 
efficiency, and the transition to renewable energy, pollution prevention and circularity. Tenaris has defined 
and implemented global procedures to ensure that suitable communication processes are established with 
contractors, visitors, local communities, and other interested parties including HSE event reporting. Our 
management system establishes the requirements to report and investigate environmental incidents and is 
fully integrated with our Health and Safety Management System, allowing us to identify and share lessons 
learned to minimize impacts and repetitive events. The most senior level accountable for implementing our 
EMS is the CEO. 
We continuously analyze the environmental impact of our operations and define and implement mitigating 
actions. The management system covers all our operations, including production processes, capital 
expenditures, and operating practices. It involves both upstream and downstream activities, with particular 
focus on our main suppliers and our oil and gas customers, as required by the ISO 14001 standard. It is 
applicable globally, then specific actions are tailored to local conditions, as actions cannot be implemented in 
the same manner at all sites. They depend on local conditions, infrastructure, policy considerations, processes, 
among others. The policy considers the interests of employees, contractors, suppliers, and local 
communities. 83% of our production sites now operate with a certified EMS according to ISO 14001. We are 
working to integrate the remaining sites, including our recently acquired sites. 
We cooperate with local governments on rational policies to help achieve the UN Sustainable Development 
Goals. We also participate in global steel industry actions particularly through our activity within 
worldsteel. We have been committed to the UN Global Compact since 2016 and disclose our progress report 
on an annual basis.

Climate Change 
Commitment 
 
To reduce the intensity of our CO2-eq emissions and reach carbon neutrality as soon as technology and 
market conditions allow.  
Objectives  
 
• 
Achieve 30% reduction in the CO2-eq intensity of our operations by 2030 from 2018 levels, as a 
mid-term target towards becoming carbon neutral as soon as technology and market conditions 
allow. 
• 
Identify and implement actions to reduce the intensity of CO2-eq emissions: e.g., increase scrap and 
low-carbon electricity usage, increase energy and materials use efficiency in operations, explore 
hydrogen and carbon capture techniques to progressively replace and/or abate fossil fuel use in 
operations. 
• 
Engage with suppliers to encourage production and use of more sustainable products, services and 
operations. 
• 
Offer customers products and services that help to minimize their footprint and support their own 
strategies. 
 
Tenaris recognizes the profound challenges posed by climate change, both to society at large and to our 
business specifically, considering the markets in which we engage, how government regulations may 
influence our operations and those of our customers, and the geographical location of our physical assets.  
At the same time, climate change presents strategic opportunities not only to strengthen our market 
leadership but also to explore new sales avenues. 
Tenaris is committed to reducing its carbon footprint and supporting the Paris Agreement goals, having set a 
mid-term intensity target that covers all our tubular operations – Scope 1, 2 and 3 for raw materials, 
including purchased steel, and intermill transportation of unfinished products. 
Given the relevance of climate change for the company’s overall business and strategy, our Board of Directors 
approves our decarbonization and climate change strategy and reviews its progress quarterly, and a Vice 
Chairman of the Board has been appointed to oversee climate-related issues. Major investments aligned with 
the decarbonization strategy are presented to the Board for approval, and the Board reviews and guides the 
strategy, annual budgets, and major capital expenditures related to climate change. 
We regularly assess and track global progress towards the energy transition, keeping an eye on policies, 
regulations, technologies and other global and national developments that could speed up or hinder the 
progress of this transition in the years to come, as well as other factors that could affect or pose particular 
risks to our sales and operations. 
We recently conducted a climate risk assessment to better understand the long-term vulnerability of our most 
relevant industrial facilities to climate effects and physical climate risk, using the Intergovernmental Panel on 
Climate Change (“IPCC”) high-emissions Representative Concentration Pathway (“RCP”) 8.5 global warming 
scenario, which showed no apparent undue exposure to risks for which Tenaris is unprepared. 
We work closely with our customers to support their efforts to establish sustainable sourcing policies across 
their supply chain, thus requiring a more detailed disclosure of climate change-related impacts. 
As we pursue our strategy of decarbonizing our operations, we are exploring various options with different 
partners around the world. We know that there is no single solution, as certain alternatives are better suited 
to specific sites or regions based on local infrastructure and resources.

EAF producer 
 
 
All our steel is produced in EAF using recycled steel scrap as the primary source of metallic feedstock. We 
supplement the use of steel scrap with metallics such as pig iron, direct reduced iron (“DRI”) and ferroalloys, 
to meet quality, productivity and materials specifications. In Argentina, where steel scrap availability is limited, 
we operate a facility to produce DRI using natural gas.  
Steel produced in EAF using a high proportion of scrap in the metallic charge has a lower carbon intensity 
than steel made using iron ore and metallurgical coal as primary feedstock. The average CO2 emissions 
intensity for our steel making sites is 0.9 ton CO2/ ton crude steel, which is less than 50% of the 1.9 ton CO2/ 
ton steel for the average global steel industry, according to worldsteel. 
We also purchase steel from third-party suppliers, primarily to manufacture welded pipe products. As many 
of these suppliers make steel products using iron ore and coal, the carbon emissions intensity of the pipes 
made with this steel is often greater than that of those manufactured with our own steel.

Our Decarbonization Levers and Actions 
 
Scope 
Decarbonization Levers 
Description 
Reducing the carbon intensity of our operations 
Increased Use of Recycled 
Steel Scrap 
We are increasing the use of recycled steel scrap in our raw material 
mix, reducing the use of pig iron without compromising product 
quality.  
Energy and Material 
Efficiency and Process 
Yield 
Energy and material efficiency is a cornerstone of our industrial 
culture, in which we continuously invest to improve operating 
practices and efficiency in the use of resources.  
Renewable Energy 
Deployment 
Transitioning to zero-carbon emission electricity by implementing 
renewable energy projects and/ or acquiring zero-emission electricity. 
Carbon Pricing and 
Regulatory Compliance 
We have used an internal carbon price since 2021 to evaluate 
investments in projects that could contribute to decarbonize our 
operations and monitor carbon pricing frameworks and trends globally 
and locally to identify regulatory mechanisms and assess transition 
risks and opportunities.  
Adoption of New 
Technologies and 
Innovative Projects 
We invest in best available technologies (“BAT”), seeking to 
continuously modernize our facilities to improve efficiency, reduce 
emissions and environmental impact, enhance safety in our 
operations, and to prepare our facilities for the use of new 
technologies such as hydrogen when they become commercially 
available. 
Training and raising 
awareness 
We train leaders and employees on key environmental aspects to raise 
awareness and commitment towards sustainability.  
Supporting the decarbonization of 
our value chain 
Supply Chain Optimization 
Through our Rig Direct® service, we synchronize production schedules 
and logistics to customer drilling operations, reducing inventories and 
redundant operations and shortening the supply chain, thus reducing 
emissions.  
Supply Chain 
Transparency 
 
We engage with our suppliers to gather climate change and carbon 
information about our main raw materials. This helps us include 
product-specific upstream emission factors in our inventory, improve 
the accuracy of our Scope 3 emissions reporting and identify 
opportunities for collaboration to reduce emissions.  
Alternative Steelmaking 
Materials 
We explore the use of alternative materials such as biomass or residues 
to replace coal and biogas thus replacing fossil fuels.  
Products for the Low 
Carbon Energy 
We invest in R&D to develop products and services that will support 
the energy transition. 
 
 
Reducing the carbon intensity of our operations 
 
In February 2021, we set a medium-term target to reduce the carbon emissions intensity of our operations by 
30% by the year 2030, compared to a 2018 baseline, considering Scopes 1, 2 and 3 emissions for purchased 
raw materials. Within Scope 3 emissions, the target considers emissions related to raw materials and steel 
purchased from third parties, by far the most relevant source of our Scope 3 emissions. The GHGs included 
are CO2, CH4 and N2O. 
 
In February 2025, we restated the baseline for our medium-term emissions intensity reduction target, to 
include (i) the expanded perimeter of our operations from the acquisitions we have made since 2018, and (ii) 
intermill transportation of unfinished products, and to adopt more realistic emission factors for certain raw 
materials and include previously excluded raw materials, in line with discussions held at worldsteel. In 
particular, we are now including our recently acquired welded pipe operations in Saudi Arabia and pipe 
coating operations. We have made these adjustments to increase reporting transparency and clarity. The net 
effect of these multiple adjustments has been to increase the overall level of intensity we are reporting under 
our target and for our operations, with the 2018 baseline intensity increasing to 1.54 from 1.43 tons CO2-eq 
per ton of steel processed. Up to 2024, a 15% reduction in CO2-eq intensity from the revised 2018 baseline 
has been achieved. For more information on the restatement of the emissions baseline please see 
“Sustainability Statement - Annexes - Annex I: Sustainability Statement Accounting Policies”. 
 
 

Annual Report 2024 
131 
Our target aligns directly with our EMS objectives of mitigating climate change impacts and promoting 
sustainable practices within our operations. The target encompasses all our operational activities related to 
tubular activities.  
The target was set analyzing our main sources of emissions and evaluating the technologies and 
modifications we could implement to define an achievable target. We evaluated our intensity and how it 
compared to other competitors and steel producers. We considered also the IEA iron & steel technology 
roadmap issued in 2020 in relation to the Paris agreement. Definition of the target took into consideration a 
medium-term timeframe compatible with our intensity, global agreements to reduce GHG emissions, 
technologies that can be implemented today at reasonable cost according to the processes we perform and 
worldsteel’s sectoral approach and decarbonization pathways. 
Performance against disclosed targets is monitored, reviewed and disclosed annually. Metrics used include 
CO2 emissions intensity, energy intensity, and the percentage of renewable energy use. Progress is evaluated 
against initial plans, and trends or significant changes are analyzed to ensure continuous improvement.  
Any changes in targets, metrics, or underlying methodologies are documented and communicated 
transparently. This includes updates to significant assumptions, limitations, and data collection 
processes. Please see “Sustainability Statement - Annexes - Annex I: Sustainability Statement Accounting 
Policies”.  
This medium-term target is a first step towards the broader objective of decarbonizing our operations and 
reaching net zero carbon emissions. How long it will take to achieve this final goal depends on the 
development of emerging technologies as well as market and regulatory conditions, including carbon pricing 
and customer support. We are allocating substantial resources to our decarbonization strategy and will 
continue to do so to strengthen our competitive position.

The following graph shows the different decarbonization levers with which we plan to achieve our medium-
term target. 
 
Over the past three years, we have increased capital investment in projects which contribute to our 
decarbonization strategy and environmental goals. These investments accounted for 29%, 31% and 30% of 
our total capital investments in 2022, 2023 and 2024, respectively, while a similar percentage is forecast for 
2025. In total, our expenditure on such projects is expected to exceed $700 million over the 2022-25 period. 
 
 
 
 

Annual Report 2024

Use of steel scrap and alternative materials 
In 2024, the proportion of recycled scrap used as raw material in our steelmaking operations reached 82%, 
up from 68% in 2018. The proportion of recycled scrap we can use at each facility depends on local 
availability, scrap quality and the steel quality requirements of our products.  
We have increased our steel’s recycling content by reducing the amount of pig iron in the metallic mix. In 
2024, we substantially reached our objective of reducing the use of pig iron in our metallic charge to 
minimum levels with the use of data science models to design the optimum charge to maximize scrap use 
while complying with steel quality standards and meeting other performance criteria. 
To secure access to scrap of the requisite quality for use in our operations at these high levels, we are 
investing in various projects to improve our scrap market sourcing ability, as well as scrap-handling and 
storage capabilities. 
In addition to using more scrap, we are also looking at increasing the recycling mix in, and reducing carbon 
emissions from, our steel furnace charge by using alternative materials where feasible. For example, our steel 
shop in Romania is currently replacing part of the coal used in the steel process with recycled waste plastics, 
today replacing around 30% of the coal used.  
Renewable energy deployment 
Following an investment of $200 million, in October 2023 we began operating a wind farm in Argentina with 
an installed capacity of 103.2 MW. The power generated is delivered through the interconnected grid to our 
industrial facilities in Campana, where it provides around 50% of total electric power consumption. We are 
currently constructing a second wind farm in Argentina, with a $214 million investment, after winning 
additional priority connection rights to the interconnected grid. This investment is expected to be operative by 
the end of 2025 and its output would meet a further 30% of current energy needs at our Campana facilities 
and reduce our CO2 emissions by a further 102,500 tons per year.  
Other investments in renewable energy include solar projects in Romania and Italy accounting for 30 MW 
installed capacity, while in Colombia, Mexico and Romania, we are buying power from certified renewable 
sources either through particular contracts or certificates. We also signed a PPA in Italy to cover a small part 
of the electricity we buy. In 2024, our consumption of renewable electricity accounted for 20% of our total 
electric power consumption including our own generation and purchases, up from 12% in 2023. We 
continue to explore other options for renewables in the different regions where we operate. 
Under a collaboration agreement between Tenaris, Snam S.p.A. –one of Europe's main energy infrastructure 
operators-, and Tenova -a related company that is a leading developer and supplier of sustainable solutions 
for the transition of the metallurgical industry-, our Dalmine mill has been carrying out a test of hydrogen 
generation and use, with the aim of evaluating the performance and reliability of generating and using 
hydrogen in the steel industry and, more generally, in hard-to-abate sectors. The goal has been to use the 
hydrogen produced on site to fuel a burner recently developed by Tenova (100% H2 ready) and installed in a 
reheating furnace for seamless pipes. The trial that lasted for 6 months has helped to define safety guidelines 
and plant management procedures, thus initiating the development of integrated solutions for the 
implementation of this type of technology. 
Energy efficiency measures 
As a company dedicated to industrial excellence, prioritizing energy efficiency has long been central to our 
continuous improvement efforts and our investments. Our aim is to modernize production lines and 
equipment, while working continuously to improve operating practices and reduce energy and material 
consumption.  
 
 

Annual Report 2024 
134 
In 2024, we replaced one of our two steel furnaces at our Siderca mill in Argentina with a modern furnace 
incorporating energy-efficient Consteel® technology. This new furnace enables the continuous charging of 
scrap which is preheated with fumes produced during the melting process, thus reducing electricity, natural 
gas and electrodes consumption compared to traditional batch-charging technologies. The new furnace 
started to operate in September 2024 after an investment of $80 million. 
We also revamped furnaces at our Italian sites and have a furnace revamping project ongoing in Sault Ste 
Marie, Canada, while many other minor improvements have been implemented to reduce electricity and 
natural gas consumption. 
Internal carbon price and financial considerations 
To facilitate the achievement of our decarbonization targets and prepare for the potential adoption of 
additional carbon pricing mechanisms around the world, in 2021, we introduced an internal carbon price of a 
minimum of $80/ton. This internal carbon price is primarily used to evaluate investments in projects that 
could help to decarbonize our operations. The internal carbon price level was decided according to existing 
local and regional carbon prices and bibliography recommending levels of carbon price to foster the adoption 
of new technologies. 
We also assess the future market outlook for our products, taking into account different oil and gas demand 
scenarios as published by our customers, international agencies like the International Energy Agency (“IEA”), 
and energy market consultancies, such as Rystad Energy (“Rystad”).  
We pay particular attention to the historical record and the potential pace of change in the adoption of new 
technologies, regulations and behaviors which could affect future oil and gas demand. We use these 
scenarios and assessments as essential input to shape and assess our business strategy, and how we address 
the risks and opportunities arising from climate change.  
The transition from the current reliance on fossil fuels, including oil and gas, to cleaner alternatives is 
uncertain, with a wide range of potential outcomes. This transition is further complicated by the ongoing 
increase in demand for energy particularly in less developed countries. 
Tenaris takes these risks into consideration when evaluating its investments in major projects and the 
acquisition of equipment to produce steel pipes, factoring them into the accounting estimates and 
assumptions used to assess the carrying value of its assets. 
Training and raising awareness 
We place significant emphasis on training and communication to foster a culture of environmental 
responsibility. We train leaders and employees on key environmental aspects to raise awareness and 
commitment towards sustainability. We communicate our policies throughout the organization, train 
employees in the use of our EMS and engage them in setting, measuring, and revising objectives.  
Supporting the decarbonization of our value chain 
We work closely with our value chain to identify opportunities for reducing carbon emissions. For instance, 
supply chain integration is a specific feature of our Rig Direct® service which aims to synchronize production 
schedules and logistics with customer drilling operations, thus reducing inventories and excess materials. We 
are also studying alternative steelmaking materials, such as biomass or residues to replace coal, or biogas to 
replace fossil fuels. 
Through our R&D and innovation efforts, we introduced Dopeless® threads years ago as a solution to reduce 
pollution at drilling sites that is used primarily in offshore operations. Combined with our Rig Direct® service, 
pipes arrive at the rig or port ready for immediate use, without the need for thread cleaning, inspection, and 
running dopes. This technology not only streamlines operations but also enhances environmental 
performance, helping our customers minimize their impact. 
 

Annual Report 2024 
135 
Our Sustainability Sourcing Policy will help us to have a better understanding of our suppliers’ real emissions 
levels in order to identify further opportunities for improvement.  
During 2024, we started to use the Open-es platform, inviting a first round of suppliers to join the platform 
to disclose their ESG practices. This initiative is framed within our Sustainable Sourcing Policy. We plan to 
continue asking more of our suppliers to join this platform to find options to collaborate and continue 
improving the sustainability performance of our value chain. 
Products for the energy transition  
As suppliers of tubular products and services to the energy industry, the energy transition provides us with an 
opportunity to develop new products and services for potentially fast-growing segments such as hydrogen 
transportation and storage, carbon capture use and storage projects, and geothermal installations. Over the 
past three years, we have increased our investments in R&D in this area, as they are expected to contribute a 
relevant revenue stream to the company in the future. We monitor global trends to estimate future energy 
needs within the context of the energy transition, where gas transmission networks will play an important 
role. 
We have developed a range of materials technologies and products that have been tested for use in 
hydrogen storage and transportation, CCS injection wells, and geothermal applications. Regarding hydrogen 
storage and transportation, we have seen growth in demand for large, high-pressure vessels used in the build 
out of hydrogen refueling stations for heavy-duty vehicles and buses. We have also seen increasing interest in 
developing geothermal, waste-to-energy and CCS projects. In particular, we recently received an order from 
Saudi Aramco for a CCS pipeline which will transport nine million tons of CO2 from refinery and 
petrochemical operations for storage in depleted oil fields. 
Resilience and adaptation 
We regularly assess the resilience of our strategy and business model in relation to climate change, covering 
our own operations and including upstream and downstream value chain considerations. In addition to the 
elements mentioned above, this analysis includes: 
• 
Board Oversight and Strategic Opportunities: Our board of directors reviews the progress of our climate 
change strategy quarterly. We recognize that climate change presents both challenges and strategic 
opportunities, enabling us to strengthen our market leadership and explore new sales avenues.  
• 
Global Energy Transition Monitoring: We regularly assess global progress towards the energy transition, 
considering policies, regulations, technologies, and other developments that could impact our 
operations. This ongoing assessment helps us stay ahead of potential risks and opportunities.  
• 
Climate Risk & Vulnerability Assessment: We have conducted a climate risk & vulnerability assessment 
using the IPCC high-emissions RCP 8.5 global warming scenario. This assessment has provided a risk map 
for our main facilities, allowing us to prioritize and implement measures to increase resilience to physical 
climate risks.  
• 
Customer Collaboration: We work closely with our suppliers and customers to support their sustainable 
sourcing policies, requiring detailed disclosure of climate change-related impacts. This collaboration 
ensures that our supply chain aligns with broader sustainability goals.  
Cumulative Locked-in GHG Emissions from Key Assets and Sold Products  
We have evaluated the cumulative locked-in GHG emissions associated with our key assets from the 
reporting year until 2030 and 2050. This assessment includes the sum of estimated Scopes 1 and 2 GHG 
emissions over the operating lifetime of our active and planned key assets. These key assets include our 
industrial facilities, and equipment that are significant sources of direct or energy-indirect GHG emissions. 
Although our steel-making process is energy-intensive, we anticipate a reduction in indirect emissions as we 
transition to low- or zero-emission electricity sources.  
 

Annual Report 2024 
136 
This trend is already underway based on our projects and will be further supported by improvements in the 
electricity grids across the countries where we operate. In terms of Scope 1 emissions, the most significant 
contributors are those associated with natural gas use in our DRI plant, as well as the energy required to heat 
and process steel for pipe production. The availability and affordability of low emission energy resources, 
including CCS infrastructure and hydrogen, in quantities necessary for assuring production and at a 
competitive price would be needed to unlock Scope 1 emissions.  
The use of steel pipe products does not generate CO2 emissions directly, as they are a stable product. Fuel 
emissions occur during the combustion of fuel, after pipes have been used for the extraction of those fuels. 
Oilfield services 
We recently started a relatively small business unit that is unrelated to our main businesses of manufacturing 
steel pipes and other steel products, which is reported under our “Others” segment. This business unit sells 
fracking and coiled tubes services to oil and gas companies operating in Argentina and involves the 
generation of CO2-eq emissions mainly related to the use of energy to power the fracking equipment. These 
operations are usually performed in remote areas without access to a grid connection with diesel used to 
power equipment. 
Emissions are majority of Scope 1 with a marginal participation of Scope 2 related to the power needed for 
offices. These emissions are not included in our target or calculation for steel and tubular intensity.  
In 2024, CO2-eq emissions for this business are estimated in: 
Scope 1: 64,262 tons. 
Scope 2: 49 tons. 
 
 

Annual Report 2024

Air Quality 
Commitment 
 
To minimize emissions of fumes and particulates, contributing to good air quality in our operations and the 
communities where we operate.  
Objectives 
 
• 
Comply with local and internal emissions requirements. 
• 
Minimize emissions from steelmaking processes. 
• 
Reduce volatile organic compounds (“VOC”) emissions related to our coating activities. 
 
Apart from CO2-eq emissions, the steelmaking process produces emissions from particulate matter and other 
pollutants that require control measures. Accordingly, we have defined corporate procedures that set strict 
limits on stack emissions and define monitoring requirements. Internal procedures have been drawn up 
according to the best technologies available to improve processes beyond legal compliance levels, as not all 
countries where we produce have the same requirements.  
In our corporate procedure on air pollution management, we set internal limits for stack emissions, especially 
on particulate emissions, that are according to BATs levels and monitored with continuous monitoring 
equipment that allows to track performance and identify opportunities to take preventive actions. This 
pollutant is one of the most relevant in an EAF operation. Other pollutants are evaluated through spot 
monitoring, also considered in our procedures and improvements are implemented when necessary. 
Abnormal events are managed as incidents according to our definition, investigated and improvement actions 
are defined. Please see “Sustainability Statement - Sustainability in Tenaris - Policies and Procedures”.  
Preventing, remediating and addressing impacts 
 
Our policies and procedures as well as our corporate internal targets regarding air quality align with best 
available control techniques, this way ensuring that we are able to define, evaluate and implement 
improvements on those criticalities going beyond legal compliance. This is applicable for air emissions 
particularly concerning dust, nitrogen oxide (“NOx”) and VOCs. Our procedures consider point source 
emissions, diffuse and fugitives within the scope. 
We have defined corporate key performance indicators that are monitored routinely to define improvement 
plans when necessary. There are global indicators, according to the criticalities internally defined and 
performance is reported routinely to top management. Sites establish also their own indicators for proper 
follow up of local situations. 
We use BATs to reduce impact and prevent pollution. Investment projects include BAT evaluation to improve 
performance beyond local compliance criteria. Changes are defined according to performance and evolution 
of BATs as well as results of improvements implemented. 
Our corporate and local targets plans are related to our commitment set in our QHSE policy of minimizing the 
environmental footprint of our activities, products and services. Targets are followed up and monitored on 
internal databases and reported to top management.  
By integrating these elements into our operations, we strive to prevent incidents and emergencies and 
mitigate their impact on people and the environment when they occur. 
Our Actions 
 
In the past years, we have made significant investments in controlling particulate emissions, including 
upgrading systems and technology at our sites in Tamsa in Mexico, while, this year, this was reinforced in 
Siderca in Argentina with the implementation of Consteel® technology when replacing one of our EAFs, and 
the modernization of our Koppel US steel shop. Consteel® technology ensures better emission management, 
as scrap is charged continuously without opening the top of the furnace.  
 

Annual Report 2024 
138 
We are reinforcing preventive maintenance, controls and operating conditions to sustain the operation as 
required. 
We continuously monitor particulate material in our steel shop stacks as this is the most relevant pollutant 
from the steel process in terms of air quality. Monitoring provides our maintenance areas with feedback so 
they can keep bag houses operating correctly. We have set internal particulate emissions standards for these 
processes.  
All revamped furnaces include low NOx emission burners and new varnishing lines for pipes are using water-
based products to minimize VOC emissions. We just started to operate a new water-based varnishing line in 
our SPIJ facility in Indonesia.

Water Management 
Commitment 
 
To ensure effective management of water resources.  
 
Objectives 
 
• 
Minimize water intake, especially in water-scarce areas where we have water-intensive operations. 
• 
Meet water discharge quality targets. 
• 
Implement the best water-management technologies for new lines. 
 
Water plays a major role in steel manufacturing processes, although little of it is consumed as most is reused 
or returned to source. Tenaris is aware of its responsibility for managing water resources efficiently and is 
constantly evaluating how best to conserve and reuse water.  
Our QHSE Policy includes a commitment to reduce our environmental footprint, including the use of water, 
and we have implemented procedures to ensure effective management. Our corporate strategy includes 
evaluating the use of water at each place, the applicable requirements, potential sources of water, trends and 
future risks for each location. Based on evaluating the situation at each location we can define improvement 
opportunities for reducing the environmental pressure on water resources whether this is on the use or 
quality. Our procedures cover all industrial sites and activities, products and services. Please see “Sustainability 
Statement - Sustainability in Tenaris - Policies and Procedures”. 
Preventing, remediating and addressing impacts 
 
In our corporate procedure on water management, we have established comprehensive measures to ensure 
the sustainable use and protection of water resources. These measures include: 
 
• 
Mapping Potential Pollution Sources: We identify and map out potential sources of pollution to 
proactively manage and mitigate any risks to water quality. 
• 
Maintenance Programs for Water Treatment Systems: Regular maintenance programs are in place to 
ensure that our water treatment systems are functioning effectively and efficiently. 
• 
Monitoring Programs: Monitoring programs are implemented to track water usage and quality both 
of water getting into the system and discharge, allowing us to identify any issues promptly. Our 
procedure establishes pollutants of interest according to the process used at the location. 
• 
Improvement Actions: Based on the criticalities identified through our monitoring programs, we 
define and implement actions to improve water management practices. 
• 
Water Stress Risk Evaluation: We evaluate water stress risk for each of our locations. This evaluation 
helps us prioritize criticalities and establish actions to improve water management at sites facing 
higher risks. 
 
We are advancing at some sites in the metering of water use, by main processes so to be able to identify 
improvement opportunities for the use of water. 
Our procedure establishes a hierarchy level on the type of water to use at each location with a general 
approach, that is then validated locally according to water availability and competing uses on the area which 
may trigger different objectives in terms of water use. 
To ensure the quality of water discharged, we regularly monitor effluent discharge to comply with local and 
internal standards. The type of treatment for effluent discharge is determined by the effluent type and 
destination, with most undergoing secondary physical-chemical treatments, especially in locations lacking 
adequate infrastructure. Our procedure establishes recommended methods for monitoring that are then 
validated according to local applicable requirements that often vary from country to country.  

Annual Report 2024 
140 
We have defined metrics measuring the amount of water used per source and per ton of product. With this 
metric we are able to track the use of water at every location. Locally, each site measures quality of 
discharges to track compliance, based on these two main metrics we are able to set improvement actions 
when problems are detected. Water stress areas and future water risk evaluations are inputs to define the 
required improvement actions. 
The process that is most intensive in water use is the rolling process, as water is used to cool down the pipe 
during its production. In most of our sites, water is used in closed water systems, so water is recycled 
internally. Discharges are monitored according to applicable legal requirements and internal procedures 
which also establish limits. 
We are subject to a wide range of local, state, provincial and national, laws and permit requirements 
concerning water management. These are relevant inputs considered when evaluating performance and 
potential improvements on water management.  
When new processes are added, water used is evaluated and BATs are applied to ensure proper 
management, together with consideration on the future water risks for the area. 
Water-stress areas 
We evaluate water stress levels at our facilities, especially those with high water-use rates for seamless pipe 
making, rolling and heat treatment, as processes for welded pipe and finishing plants use less water, in 
accordance with the World Resources Institute’s Aqueduct global water risk mapping tool. Only 0.6% of our 
total water withdrawal is located in high to extremely-high water stress areas; 0.3% is located in medium to 
high stress areas, and around 99% is located in low / low-to-medium areas. Most of our more intensive 
water-use facilities lie in areas of low or medium water stress risk, according to the Aqueduct Water Risk 
Atlas, and these sites currently display high recycling rates. Our water management procedures cover all 
areas, including those dealing with high-water stress.  
 
We have also incorporated tools to map and evaluate climate related risks affecting the areas where we 
operate, including water related risks such as flooding or droughts, to evaluate adaptation measures that may 
be required at our locations. 
Oceans and seas 
 
We have not adopted any policies specific to oceans and seas, as we do not have operations directly 
impacting oceans or marine resources. However, we do acknowledge that some discharges in rivers or lakes 
could eventually end up in the ocean. Our water procedures mentioned above aim at managing these risks.  

Annual Report 2024 
141 
Our Actions 
 
During the year, we modified our internal procedures to better acknowledge the potential impact of heavy 
rains in different locations and we included considerations for the analysis of modified and new buildings, as 
there are changes happening, we need to be prepared to collect more water in short periods of time and 
manage it on our installations. 
We are implementing an investment project in Sault Ste Marie to improve water treatment before discharge, 
and we have another project ongoing in Bay City for doing the same. In Zalau, Romania, we implemented 
improvements on water treatment, as well as in Tamsa. We have approved a project in Siderca, Argentina to 
allow for a better water collection and management to reduce risk of flooding in an area of the site and also 
improve treatment of particular streams. 
Our products can also help our customers in their water management and use. For example, our Dopeless® 
connections require no water for cleaning threads when in the field, while a standard dope thread needs 
between 10-20 liters of water per connection.  
 
 

Annual Report 2024

Circularity 
Commitment 
 
To implement circular economy concepts throughout our industrial system. 
 
Objectives 
 
• 
Maximize recycling rates at our facilities. 
• 
Maximize scrap availability and use. 
• 
Reduce the amount of materials sent to landfill by reducing generation, reusing and recycling, 
including revalorization. 
• 
Minimize pollution. 
 
Our QHSE Policy provides a framework for improvements in resource management, circular economy and 
material efficiency. According to our management system structure and objectives, we have established 
internal procedures to regulate the material, waste and chemicals management. Please see “Sustainability 
Statement - Sustainability in Tenaris - Policies and Procedures”. 
 
As a process of continuous improvement, we look for opportunities to reduce consumption, select better 
materials, reuse and recycle internally or externally and finally decrease the amount of wastes generated and 
sent to landfill. 
 
Our waste management procedure sets guidelines to ensure that we minimize environmental impact and 
promote sustainability. Here’s how our procedure addresses each stage: 
 
• 
Prevention: we prioritize the minimization of waste generation by implementing BATs in our CAPEX 
projects. This includes new manufacturing lines, processes, and revamping existing ones. We aim to 
reduce waste at source in the projects we implement. We evaluate wastes generated at our normal 
activities to identify waste streams looking to minimize generation. 
• 
Preparing for Re-use: we evaluate our processes to find opportunities to re-use materials and waste, 
both internally or externally in other industrial processes. Our procedure includes stringent rules for 
the storage of products and wastes, which help in maintaining their quality for potential re-use. 
• 
Recycling: we have set internal indicators, and we follow up generation of waste looking to reduce 
generation, reuse them whenever possible and recycle, making disposal a last resort. 
• 
Other Recovery: we use other recovery options, such as energy recovery, to make use of waste that 
cannot be prevented, re-used, or recycled. This is part of our broader commitment to use natural 
resources and energy efficiently and contribute to the circular economy. 
• 
Disposal: we ensure that waste disposal is conducted in a manner that minimizes environmental 
impact. Disposal activities are performed with authorized companies according to applicable local 
requirements. 
 
Significant resources and efforts are dedicated to identify recovery, reuse and recycling opportunities and 
finally decrease the amount of waste sent to landfills. 
We are committed to working with our suppliers to improve sustainable business practices, assisting them to 
identify risks and opportunities, providing training, sharing knowledge and raising awareness, and, in general, 
working together to improve the sustainability of our supply chain and our business.

Our Actions 
 
Recycling scrap  
As we produce steel using EAFs, the use of recycled scrap is a key aspect of our operations. We have 
implemented practices to increase the use of recycled scrap. The use of recycled scrap reduces the use of 
virgin materials (like iron or coal), reduces CO2 emissions related to the steel process and enhances circularity. 
As a permanent resource, steel is fundamental to achieving a circular economy: it can be recycled infinitely 
without losing any of its properties. This is a way of saving energy, in addition to iron, coal and other 
materials, as well as producing less CO2 emissions, and preventing useful material from ending up in landfill 
as waste. We focus on several key areas to ensure efficient resource inflows, outflows, and circular product 
design. 
We rely heavily on scrap recycling which is also shown on the recycling rate for our steel which reached 82% 
in 2024.  
 
We are investing significant amounts in scrap management, particularly in Mexico, but also in Romania and 
Argentina. In order to increase steel production based on scrap, internal models have been developed to 
support higher use of scrap and less pig iron, while maintaining product quality. Scrap often contains 
impurities, particularly copper, that pose a risk for cleaner steel production. We carefully evaluate our sources 
of scrap to minimize this risk of impurities and to reduce the need for purer iron sources such as pig iron.  
In Argentina, the quantity of scrap that can be sourced locally is limited. Thus, to complement locally-sourced 
scrap in the steel charge, we process iron ore pellets into DRI on site using natural gas to complete the metal 
charge necessary for operations.  
Material management 
Production phase 
We are also exploring the use of alternative materials in our steel furnaces. In Romania, we are participating 
in the Retrofeed program to test alternative materials for steelmaking and are now using plastic wastes to 
partially replace coal. As another example, in our facility in Argentina, where we produce our own plastic 
thread protectors, we have moved from 30% content of recycled plastic to 60% in average.  
We reuse and recycle residue and co-products to cut waste: in 2024, our disposal amounted to 9.7%.  
 
 

Annual Report 2024 
144 
 
We have maintained reuse and recycling rates for our co-products, with higher volumes for slag, followed by 
scale and iron fines. Slag, the major waste co-product, is reused and recycled in areas such as building 
materials, fillers, road surfacing, and concrete, while scale, the second co-product, is used in cement 
processing or by other steel companies. 
Our industrial operations in Brazil, Italy, Mexico, Romania and the UK have achieved waste recycling rates of 
over 90% (excluding scrap), the result of continuous efforts to minimize waste generation and landfill as a 
treatment method. 
We also continue with our thread protector recycling program in many regions where we operate, reusing or 
recycling plastic protectors to make new ones or other plastic products. 
Use phase 
 
During the use phase, our experts work closely with customers to maximize operational safety and minimize 
environmental impact. By optimizing the use and service life of materials, we ensure that less material is 
needed, transported, and handled, resulting in a lower overall impact. We have implemented recycling 
services focused on plastic protectors to minimize the loss of packaging material. Recovered thread protectors 
can be used to produce new protectors at our facilities, or they are cleaned, shredded and used to produce 
new plastic products.  
End of functional life 
 
At the end of a product's functional life, our focus on recycling and reusing materials ensures that they are 
not wasted. This approach aligns with our goal of achieving a circular economy by promoting reuse, repair, 
refurbishing, remanufacture, repurposing, and recycling.  
We have achieved a high level of material efficiency (a worldsteel indicator), reaching 98.8% in 2024 for our 
steel sites, which is above the industry average, according to worldsteel. This efficiency is a result of our 
efforts to reuse and recycle residues and co-products, thereby cutting waste.

Biodiversity 
Biodiversity has not been identified as a material topic for our company, but we acknowledge that its 
connection to climate change and pollution is gaining global significance as awareness grows about the 
impact of business activities and climate change on plant and animal diversity. 
We are improving our management and governance approach to acknowledge and address the impacts on 
biodiversity and climate change and conduct targeted activities in specific regions to engage with and 
contribute to local ecosystems. 
We conducted an assessment to identify if our sites are located within or close to key biodiversity areas. The 
assessment was conducted for all of our steel production sites around the world as well as our downstream 
processing sites on biodiversity, applying online platform on Biodiversity Risk Filter from World Wildlife Fund 
(“WWF”) and Key and Protected biodiversity data. 
We identified two industrial operations less than 10 km away from key biodiversity areas: Qingdao and 
Calarasi. One of them is a steel shop located in Calarasi Romania that is under the European program Nature 
2000. The other is located in China, where Tenaris has a finishing facility with low impact on these topics as it 
is a line with low environmental risks. In Romania, the site acts as required by local authorities if endangered 
species are identified within the facility on one side, and on the other the site has an implemented 
environmental management system, externally certified, to ensure environmental footprint is evaluated and 
key aspects are identified to be improved along the years. Affected species were identified also for other 
sites, that may be close to critical areas for being known internally and to develop awareness among our 
employees.  
Our Actions 
In Argentina, Tenaris signed an agreement with the Rewilding Argentina foundation in 2021 to work 
together in partnership to conserve and restore local fauna in different projects throughout Argentina. These 
include the Esteros del Ibera reserve in Northeast Argentina, El Impenetrable in the North, and two areas in 
Patagonia.  
Rewilding Argentina is part of the Tompkins Conservation organization, whose work in Esteros del Ibera to 
create a successful conservation model was ranked by the National Geographic Society as one the top seven 
best projects of its kind in 2020.  
Tenaris contributes by supplying pipes to build corrals, bridges or cages to support efforts to reintroduce local 
fauna such as ocelots, jaguar, giant otter and several local bird species.  
In the “Ciervo de los Pantanos” National Park neighboring Siderca, Tenaris has provided support for local 
technical school students to build sustainable domes aimed at encouraging schoolchildren to participate in 
the educational activities organized by the National Park. At Siderca we are undertaking an evaluation of flora 
in order recreate a corridor for native flora. 
Other sites have implemented biodiversity initiatives, in general together with local NGOs or authorities to 
better define potential contributions. For example, in the United States, our Bay City mill is developing a plan 
to manage wild deer in the area while developing volunteer programs.

EU Taxonomy (Article 8 of Regulation (EU) 2020/852) 
The following information is provided in accordance with Article 8 of Regulation (EU) 2020/852 of the 
European Parliament and of the Council, as supplemented by Commission Delegated Regulation (EU) 
2021/2139 of 4 June 2021, Commission Delegated Regulation (EU) 2021/2178 of 6 July 2021, Commission 
Delegated Regulation (EU) 2022/1214 of 9 March 2022, Commission Delegated Regulation (EU) 2023/2485 
of 27 June 2023 and Commission Delegated Regulation (EU) 2023/2485 of 27 June 2023 (collectively, the 
“Taxonomy Regulation”). 
Tenaris’s Tubes segment includes the production and sale of both seamless and welded steel tubular products 
and related services mainly for the energy industry, particularly casing and tubing, or OCTG used in oil and 
gas drilling operations, and line pipe used in the transportation and processing of oil and gas as well as for 
other industrial applications. Our processes include steel manufacturing and its transformation into tubular 
products. 
Business activities included in this segment are largely dependent on the oil and gas industry worldwide, as 
this industry is a major consumer of steel pipe products. 
Major oil and gas companies are adapting their strategies and increasing their investments in renewable 
energies to address the energy transition while maintaining their capability to meet market demand and 
reduce the emissions from their operations. 
As the energy transition advances, demand for our products and services for low-carbon energy applications, 
such as geothermal, hydrogen and CCS, is expected to increase, while demand for oil and gas applications 
may decrease. 
Additionally, as part of our efforts to address climate change, we are investing in adapting our operations in 
line with our target to reduce their carbon emissions intensity rate by 30% by the year 2030, compared to a 
2018 baseline. 
The steel we manufacture to produce seamless pipe products is produced in EAFs using recycled steel scrap 
as the primary source of metallic feedstock. Steel produced in EAFs using a high proportion of scrap in the 
metallic charge has a substantially lower carbon intensity than steel produced using iron ore and metallurgical 
coal as the primary feedstock. 
On the other hand, to produce welded steel pipe products, we purchase steel coils and steel plates from third 
parties, much of which is produced in blast furnaces. 
Identification and assessment of economic activities 
Taxonomy eligibility 
We have examined all the economic activities carried out by Tenaris and have identified the following two 
activities as taxonomy-eligible economic activities, in accordance with the Taxonomy Regulation: 
1) 3.9 Manufacture of iron and steel, Nace Code C24.20 Manufacture of tubes, pipes, hollow profiles and 
related fittings, of steel (“steel tubes manufacturing”); and 
2) 4.3 Electricity generation from wind power, Nace Code D35.11 Production of electricity (“wind power 
electricity generation”). 
Taxonomy alignment  
Substantial contribution  
 
An economic activity is taxonomy-aligned if it complies with technical screening criteria of substantial 
contribution to one of the six environmental objectives and Do No Significant Harm (“DNSH”) of any of the 
other five. Additionally, the company shall prove its alignment with the minimum safeguards.  

Annual Report 2024 
147 
For fiscal year 2024, we have concluded that both taxonomy-eligible activities performed by Tenaris— steel 
tubes manufacturing and wind power electricity generation—substantially contribute to climate change 
mitigation (“CCM”) based on the technical screening criteria for substantial contributions to CCM, set forth 
in the Taxonomy Regulation as described below:  
Steel tubes manufacturing: According to the technical screening criteria set out in Annex I of the Commission 
Delegated Regulation (EU) 2021/2139, the activity “3.9. Manufacture of iron and steel” contributes to CCM 
if the activity complies with one of the following technical screening criteria:  
 
• 
GHG emissions applied to electric arc furnace (EAF) high alloy steel do not exceed = 0.266116 t CO2-
eq product (Scopes 1 + 2), and/or;  
 
• 
Steel scrap input relative to product output is no lower than 70% for the production of high alloy 
steel. 
 
Tenaris can demonstrate compliance with the second criterion of steel scrap input relative to product output, 
as it manufactures steel in EAF producing high alloy steel, and the steel scrap proportion at the consolidated 
level is higher than 70%.  
As explained above, we only produce steel required to manufacture our seamless steel pipe products, 
whereas in order to make our welded steel pipe products, we purchase steel coils and steel plates from third 
parties. Therefore, for the alignment analysis, we have excluded welded tubular products because we lack 
information regarding the steel purchased from third parties, for the purposes of ensuring taxonomy 
alignment.  
Wind power electricity generation: this activity generates electricity from wind power and contributes to 
reducing Scope 2 emissions. 
 
Do No Significant Harm (“DNSH”) 
 
We have analyzed the DNSH criteria for both taxonomy-eligible activities that contribute substantially to CCM 
by assessing those sites where we perform those economic activities. 
We have conducted an assessment of all the DNSH criteria. The rationale for our compliance with the DNSH 
regarding our tubes manufacturing activities is given below. 
Climate change adaptation 
Regarding the DNSH for Climate Change Adaptation, a physical climate risk assessment was performed in 
2023 in accordance with the Taxonomy Regulation.  
The DNSH for Climate Change Adaptation requires the company to perform a Climate Risk and Vulnerability 
Assessment to establish the adaptation capacity of its economic activity according to the climate scenarios 
defined by the IPCC up to 2050. This assessment varies in line with the lifespan of the activity according to 
the best available methodology for Climate Risk and Vulnerability Assessment. 
Risk assessment is conducted by taking into consideration exposure, climate hazards, and the vulnerability of 
the economic activity.  
Firstly, we identified the climate risks for a selection of Tenaris’s main assets in different scenarios, and for 
different time horizons. This part of the assessment also provided us with ratings for the different climate 
hazards at each location. 
Secondly, we selected the assets with a high level of climate hazard gravity and likelihood in accordance with 
climate projections and regional scenarios. For these seamless pipe manufacturing plants, which are eligible 
for EU Taxonomy, we performed a full Vulnerability Assessment. 
Thirdly, we assessed the vulnerability of these assets with regard to the climate risks identified. This resulted 
in a list of potential consequences arising from the climate events, and severity scores qualifying these 
consequences.  
 

Annual Report 2024 
148 
The last step consisted of building a Risk & Vulnerability Matrix to serve as a basis to determine the need for 
an adaptation solution plan. Overall physical risk scores were obtained by multiplying likelihood scores 
(ratings) and severity scores. 
The Climate Risk & Vulnerability Assessment concludes that none of the sites requires an adaptation plan for 
any of the climate risk categories under the RCP 8.5 scenario in 2050. Indeed, the highest overall physical 
score is 12 (medium) for the wind risk at Tamsa. 
 
Sustainable use and protection of water and marine resources 
Tenaris has procedures in place covering water use and protection. These include mapping potential pollution 
sources, implementing maintenance programs for water treatment systems, monitoring programs and 
defining improvement actions depending on the criticalities identified. Water stress risk is evaluated for each 
location, allowing Tenaris to prioritize criticalities for different sites and establish the definition and 
implementation of actions to improve water management. Furthermore, 83% of our production sites are 
working under management systems certified according to ISO standards.  
Pollution prevention and control 
Tenaris possesses all the requisite EU and national legal authorizations indicated for the use of chemical 
substances, including some carcinogenic, mutagenic or reprotoxic (“CMR”), applicable to its manufacturing 
process for seamless steel pipes according to local applicable requirements. In its current formulation, 
Appendix C does not provide any concentration limits, except for point (a) and (b). 
The criterion in point (g) aims to broaden the list of substances to which Appendix C potentially applies. It 
seeks to identify substances—whether on their own, in mixtures or making up an article—that meet the 
criteria outlined in Article 57 of Registration, Evaluation, Authorisation and Restriction of Chemicals 
(“REACH”) but are not yet included in the Candidate list, which makes it challenging for Tenaris to map 
unauthorized substances.  
Moreover, the requisites deemed “essential for society” or of “essential use” have no legal definition. In an 
official note published in December 2022, the EC claimed that it was drawing up a document to clarify the 
application of the requisite in question. However, as of the date of this report, no official document has been 
issued on the matter.  
The compliance rationale adopted by Tenaris is aligned with one of the “essential for society” criteria 
enshrined in the Montreal Protocol.  
 

Annual Report 2024 
149 
This is the same as the one cited by the EC as reference, whereby all economically feasible steps have been 
taken to minimize the essential use and any associated emission of the controlled substance.  
Protection and restoration of biodiversity and ecosystems 
As previously explained, 83% of our production sites, including our major sites, are working under 
management systems certified according to ISO standards. Main sites were evaluated to determine if they are 
located within key biodiversity areas. Our analysis showed that none of our major sites, including steel 
processing and/or rolling mills lie inside these areas. The sites located near Key Biodiversity Areas have 
implemented controls on environmental aspects that may impact on these aspects.  
Similarly, the wind farm meets the different DNSH criteria. As it is located onshore, Tenaris is not required to 
perform any assessment with regard to water protection. In terms of the circular economy objective, the wind 
turbines components are durable and resistant, and their output has a material efficiency of 90%. The 
components of the wind turbines are also highly recyclable. Finally, the wind farm is not located in or near 
any key biodiversity area, and therefore does not require any specific assessment. However, this aspect is 
included in the local environmental permits for the wind farm and a particular evaluation for potential 
impacts was performed for obtaining the license for the site. 
Minimum Safeguards (“MS”) 
 
The final step for determining taxonomy alignment is compliance with minimum safeguards to ensure that 
the company has adopted procedures implemented to ensure the alignment with the OECD Guidelines for 
Multinational Enterprises and the UN Guiding Principles on Business and Human Rights, including the 
principles and rights set out in the eight fundamental conventions identified in the Declaration of the 
International Labour Organisation on Fundamental Principles and Rights at Work and the International Bill of 
Human Rights.  
Tenaris has adopted adequate policies and procedures to ensure that both taxonomy-eligible activities comply 
with the MS. 
We understand that conduct of business by our employees, officers and directors, as well as by other 
participants along our value chain, plays a central role in complying with MS. Our Code of Conduct includes 
provisions covering, among other topics, human rights, corruption and bribery, taxation and fair competition. 
Throughout this report (in particular in our “Governance” chapter), we describe in detail our commitment, 
objectives and actions to ensure a corporate culture of transparency and integrity, based on ethical behavior 
and compliance with the law. 
Key performance indicators (“KPIs”)  
Definition and calculation of KPIs  
 
KPIs required to be disclosed in connection with taxonomy-eligible and taxonomy-aligned activities have been 
calculated based on the accounting policies applied in the consolidated financial statements, prepared in 
accordance with IFRS. 
Total turnover 
Turnover KPIs represent the proportion of net turnover derived from products or services that are taxonomy-
eligible, and the proportion of net turnover derived from products or services that are taxonomy-aligned. 
Taxonomy eligibility: all sales derived from our Tubes segment have been considered as taxonomy-eligible: 
• 
numerator: sales derived from the Tubes segment. 
• 
denominator: total sales as disclosed in the consolidated income statement. 
 
 

Annual Report 2024 
150 
Taxonomy alignment: revenues derived from the sale of seamless tubular products have been considered 
taxonomy-aligned (based on the applicable technical screening criteria). We have excluded revenues derived 
from sales of welded tubular products because we lack information with respect to the steel purchased from 
third parties for the production of welded pipes, for the purposes of ensuring taxonomy alignment. 
• 
numerator: sales of seamless tubular products. 
• 
denominator: total sales as disclosed in the consolidated income statement. 
 
For further information on our turnover calculations, please refer to note II. S “Accounting policy – Revenue 
Recognition” in our consolidated financial statements for the year ended December 31, 2024. 
Capital expenditures 
CapEx KPIs represent the proportion of capital expenditures in taxonomy-eligible activities and the proportion 
of capital expenditures in taxonomy-aligned activities. CapEx includes taxonomy-eligible investment which is 
part of a plan to upgrade a taxonomy-eligible activity into a taxonomy-aligned activity; for example, the 
construction of our wind farms in Argentina. 
Taxonomy eligibility:  
 
• 
numerator: capital expenditures for the Tubes segment. 
• 
denominator: aggregate capital expenditures disclosed in the consolidated statement of cash flow. 
 
Taxonomy alignment:  
 
• 
numerator: capital expenditures in our seamless tubular products production facilities plus capital 
expenditures for the construction of our wind farms in Argentina, plus other investments in 
environmental and energy saving projects. 
• 
denominator: aggregate capital expenditures disclosed in the consolidated statement of cash flow. 
 
For further information about capital expenditures calculations, please refer to “Information on the Company 
– Business Overview - Capital Expenditure Program” in this annual report. 
Operating expenditures  
OpEx KPIs represent the proportion of operating expenditures in taxonomy-eligible activities and the 
proportion of operating expenditures in taxonomy-aligned activities. 
OpEx KPIs are calculated as follows:  
Taxonomy eligibility:  
 
• 
numerator: maintenance expenses plus research and development expenditures corresponding to the 
Tubes segment cost of sales. 
• 
denominator: maintenance expenses plus research and development expenditures on a consolidated 
basis. 
 
Taxonomy alignment:  
 
• 
numerator: maintenance expenses plus research and development expenditures made at our 
seamless tubular products production facilities, and at our wind farm in Argentina. 
• 
denominator: maintenance expenses plus research and development expenditures on a consolidated 
basis.

Headcount evolution 
 
   
 
 
From December 2023 to December 2024, our workforce decreased by 3,260 people. Approximately half of this 
reduction was due to employees who joined the company following the acquisition of Mattr’s pipe coating 
business, with temporary project-based contracts that, in many cases, ended during that year. Additionally, once 
functions and tasks were restructured, many of these employees left the company. This reduction in personnel 
was primarily observed in Indonesia and Mexico. The other half of the reduction was a consequence of a decrease 
in plant workload, resulting in a lower requirement for personnel. These changes have been necessary to maintain 
operational efficiency and to adapt to changing market conditions. 
 
During 2024, the resignation rate for professional employees went down from 4.2% to 3.8% reaching the lowest 
value of the last 10 years. Overall (professional and shop floor employees), the resignation rate also decreased, 
from 5.0% to 4.4%. 
 
 

Annual Report 2024

Our Actions 
 
Our people, their ideas, efficiency, and skills, are our most valued asset, driving innovation and business growth. 
As a global industry leader, we face a world dynamic with economic and political uncertainties, technological 
disruption, and trade conflict. Nurturing the competencies and determination of our teams is crucial to unlocking 
a sustainable future. 
 
Engaging with our employees 
 
Our engagement with employees includes an effective Employee Value Proposition that embraces a safe work 
environment, open dialogue throughout the organization, challenging goals and projects, competitive annual 
total rewards, and career opportunities. 
 
Frequent dialogue and exchange between managers and their teams take place through different channels, 
quarterly feedback check-ins, town halls, employee opinion and pulse surveys, and performance reviews. These 
methods ensure continuous and open communication with our workforce, allowing us to assess, validate, and 
manage impacts, risks, and opportunities effectively. 
 
Our CEO hosts quarterly town hall meetings open to all professional employees worldwide, where he comments 
on business progress and answer questions on any topic raised by the audience. Other town halls are held 
regularly by regional presidents and functional directors. 
 
The Employee Opinion Survey (“EOS”) is carried out every two to three years, applicable to both professional and 
shop floor employees. Pulse Surveys are conducted between the EOS, mainly for professional employees. These 
surveys provide direct feedback from our workforce, allowing us to understand their concerns regularly. 
 
Mechanisms for identifying and addressing concerns are accessible to the entire population without 
discrimination. These include one-on-one discussions with a Human Resources Business Partner (“HRBP”), or 
Employee Relations Manager, and opportunities to provide upward feedback on supervisors as part of the annual 
Performance Management Process (“PMP”), where comments are reviewed by the supervisor’s manager. Internal 
client-supplier feedback is also allowed. For those seeking greater confidentiality, options like the EOS are 
available, along with anonymous and confidential channels, such as the Compliance Line. 
 
Attracting talent 
 
As a global company, we can offer career development and rotation prospects that are an attractive differential 
for industrial and administrative profiles.  
 
Our Global Trainee Program (“GTP”) is a strategic initiative that aims to cultivate the next generation of leaders by 
providing training in technical and soft skills. It includes structured rotation across various roles, exposure to 
industrial scenarios, and mentorship. This program emphasizes the importance of sharing company values and 
learning about our culture at an early stage, ensuring that global trainees are well-integrated and aligned with our 
organizational goals from the beginning. 
 
We established a corporate university, TenarisUniversity (“TU”), in 2005, which is responsible for providing 
training and development opportunities to all our employees at every stage of their career with Tenaris. Training 
and professional development programs, some of which are developed in partnership with external universities, 
such as Rice University in Houston, are organized with a view to promoting a corporate culture of excellence in 
everything that we do and the alignment and cross-fertilization of knowledge across Tenaris. Currently, we are 
focused on expanding the digital mindset and embracing new technologies to improve processes, achieve greater 
efficiency, and reduce transactional tasks. 
 
 

Annual Report 2024

Training  
 
TU is responsible for the continuous training of all employees, including both operational and professional staff. 
TU conducts various global programs for targeted audiences to develop fundamental skills for their roles, ensuring 
our workforce is prepared for the evolving demands of a sustainable economy. Our programs have been 
revamped to incorporate advancements in learning and technology, offering participants effective networking 
opportunities and integrating peer learning communities to enhance both technical and soft skills. 
  
As part of our structured development initiatives, we offer a series of global programs designed to strengthen 
leadership and professional capabilities. The TenarisUniversity Induction Camp (“TUIC”) is the first global in-
person program, bringing together young professionals from around the world to immerse themselves in Tenaris’s 
core values and processes while fostering networking and diversity. The Management Essentials program (“ME”), 
delivered in a virtual format, equips new supervisors with the necessary skills and tools to navigate their first 
leadership roles, emphasizing adaptive leadership and behavioral focus over purely technical knowledge. The 
Management Development Program (“MDP”), conducted in person, focuses on leadership concepts and key 
elements for middle management. The Advanced Management Program (“AMP”), also in person and delivered in 
partnership with Rice University in Houston, US, builds on previous leadership programs and introduces strategic 
concepts. 
  
Beyond leadership programs, we offer job-specific training that is learner-centric, allowing employees to train at 
their own pace and from anywhere. Our partnership with the Degreed learning platform enables users to learn, 
develop, and measure their skills in line with the latest trends. In addition to mandatory and formal training, 
employees have flexibility and autonomy in self-selected learning through this platform, which serves as a unified 
access point for all educational content in the organization, including internal systems, external providers, and an 
open ecosystem of online resources. 
  
TU continuously reviews the content, structure, and dynamics of its programs to ensure they remain aligned with 
business needs and leadership development objectives.

Diversity 
 
For Tenaris, workplace diversity is seen as a pillar for creating and maintaining a positive company culture, 
contributing to productivity, employee retention, and job satisfaction. A diverse mix of ages, abilities, and 
nationalities, as well as efforts to enhance gender equality, are seen as necessary to establish inclusion at all levels. 
 

Annual Report 2024 
160 
 
 
As a company that prioritizes internal growth, we have implemented programs to foster the development of our 
female talent, including long-term career planning and support. These efforts are part of our broader objectives to 
foster trust, empower employees, and embed sustainability values through transparent and effective processes. 
 
 
 
 
We continuously look to promote diversity and inclusion initiatives with the aim of fostering equal opportunities 
for all employees. For example, there are regional programs focused on integrating individuals with disabilities 
into the company. In many regions, diversity committees have been established, composed of employees from 
various levels of the organization, with the goal of achieving best practices related to diversity and inclusion.  
 
All new hired employees are trained in our Code of Conduct, which expressly forbids harassment of any kind in 
the workplace. There is a protocol available in the regulatory system which promotes a work environment free of 
harassment. Also, all shop floor employees and technical leaders have a mandatory training on this topic, “Positive 
Workplace: How to create workplaces free of harassment”.

Health and Safety 
 
Commitment 
 
To take care of our employees and contractors, looking after their safety, health and well-being, with safe and 
healthy workplaces throughout our industrial and office facilities.  
 
Objectives 
 
• 
Consolidate a strong health and safety-oriented culture within the company and our value chain. 
• 
Intensify preventive activities, particularly regarding high-risk activities. 
• 
Promote awareness and behaviors that enhance physical and mental well-being among all employees. 
• 
Establish a workplace free from fatalities and severe injuries. 
We have implemented policies and procedures to identify and manage impacts, risks and opportunities related to 
our employees and contractors, focusing on health, safety and well-being. 
 
The health and safety (“H&S”) Management System is based upon our Quality, Health, Safety and Environment 
(“QHSE”) Policy through which management and risk assessment fundamentals are integrated in all business 
processes. Tenaris communicates this policy throughout its organization, trains its employees in the appropriate 
use of its QHSE management system and engages them in the regular setting, measuring and revision of 
objectives. 
 
As described in the QSHE Policy, all injuries and work-related illnesses can and must be prevented. We are 
committed to maintaining safe and healthy workplaces and to promote wellbeing at work and a healthy lifestyle. 
We ensure that everyone is accountable to act proactively to eliminate hazards, reduce risks and identify 
opportunities for improvement, and encourage an open communication with all our people and interested 
parties. 
 
Following relevant events, we develop cross-site action plans and a comprehensive preventive program to leverage 
the hierarchy of risk controls.  
 
We include all contractors working at our sites in the Tenaris Safety Management System to ensure our 
prevention programs are effective. Following three fatal accidents involving contractor employees in 2023, we 
revamped our Contractor HSE Management Process to ensure the integrity of all contractor personnel, defining 
more stringent requirements and onsite prevention activities.  
 
Tenaris applies its QHSE Policy across its supply chain to support sustainable development, requiring suppliers to 
adhere to core safety principles, among other principles established in the Policy. Tenaris also expects these 
standards to be upheld within suppliers' own supply chains. 
 
During late 2023 Tenaris incorporated Mattr’s pipe coating facilities into its operations and is undergoing an 
integration process to extend the H&S Management System to those locations. 
 
Engaging with our employees and contractors 
 
Tenaris is committed to training all its employees in the appropriate use of its QHSE management system, 
strengthening its management through updating of professional and managerial skills, fostering diversity, 
encouraging the consultation and participation of workers in issues related to health and safety and taking care of 
the environment, emphasizing employee evaluation and motivation, and complying with the ethical principles 
established in its Code of Conduct.  
 

Annual Report 2024

Our Actions 
 
Foundational priorities 
 
Our employees’ safety and well-being are a priority, essential to our success and long-term sustainability as an 
organization, and intrinsic to the relationships we build with our local communities, suppliers, customers, and 
investors. As stated in our QHSE Policy, Tenaris prioritizes employee well-being by creating and maintaining a 
safety culture that seeks to deliver a workplace with no fatalities or serious injuries. We are continuously 
implementing initiatives to reduce the risks of complex activities by moving towards “error proof” solutions and 
“fail to safe” processes. 
 
Our QHSE Policy is available on Tenaris’s website at: www.tenaris.com/en/products-and-services/qhse-
certifications. Information contained in or otherwise accessible through our Internet website is not a part of this 
annual report. 
 
   
 
 
Our industrial system, operating at a high standard throughout the year, has performed well in terms of 
supporting our positioning worldwide. However, a fatal event occurred at the end of 2024 involving two of our 
employees. We deeply regret this loss of life and will continue reinforcing our preventive activity on high-risk 
activities. 
 
Leading a positive safety culture 
 
Tenaris’s commitment to safety is deeply rooted in our culture, a mission to ensure an environment where every 
employee feels safe, valued, and empowered to contribute. Safety practices depend on gaining insights from 
everyday work, standardizing the lessons learned to prevent future incidents, and constantly enhancing control 
measures to make them more effective.  
 
We believe that quality leadership is essential to strengthening our health and safety performance and to creating 
the right mindset to achieve better results. We are continually training our leaders to create “psychologically safe” 
environments, where people can discuss safety issues freely and openly. Shop-floor employees are encouraged to 
participate actively by pointing out unsafe conditions, sharing their views, and reporting any opportunities for 
improvement identified in their area in the system. 
 
Our leaders are tasked with promoting participation and communication, especially during instances like our Safe 
Hour, where they hold conversations with shop-floor employees to better understand how tasks are carried out, 
building better connections with operators on the frontline.  
 

Annual Report 2024 
163 
The Safe Hour program is continuously being refined to encourage dialogue and comments about “work as 
done” versus “work as imagined”. Operators are also invited to contribute ideas to improve working conditions. 
The focus is on ensuring actions and tasks are correctly executed, publicly recognizing people for their positive 
contributions to foster an environment of greater trust and collaboration.  
 
In 2024, we continued improving how to respond to human error by changing attitudes, shifting the focus from 
blaming to learning, emphasizing processes rather than people. A specific training campaign on Human and 
Organizational Performance (“HOP”) was launched in the U.S., Mexico and Italy and specific local actions defined 
through internal workshops. 
 
We are currently exploring artificial intelligence solutions for video analysis using our video cameras (in compliance 
with legal requirements), to help in the detection of potential high-risk situations, analyze them and define actions 
to mitigate risks. 
 
Every employee at all levels is expected to actively contribute to prevention efforts. Specific personal objectives are 
defined on preventive activities to be performed in the field and we use online tools for ongoing monitoring to 
support and motivate individuals to continually improve in this area. But most important we are focusing on the 
quality of the preventive activity, promoting a coaching in the field done by HSE people. 
 
Leveraging training and communications  
 
Putting safety at the heart of industrial growth and transformation involves substantial investment in training and 
communications. We believe everyone can help to prevent accidents and incidents and contribute to a culture of 
excellence and responsibility.  
 
Recognizing the crucial role played by supervisors and managers in growing a safety culture, we are now training 
leaders in HOP to improve risk mitigation strategies and strengthen fail-safe capabilities. Through webinars held 
initially for leaders in the U.S., Mexico and Italy, the idea is to integrate HOP principles into preventive activities.  
 
The HOP approach centers on people and their roles, working with shop-floor employees who are closest to the 
potential risks to design and test risk controls. This line of action enhances our understanding of how individuals 
perform their jobs. The endgame is to build systems that are more robust and error-proof, taking into account 
human error.  
 
A specific training on ‘Root Cause Analysis’ methodology has also been launched globally with the aim to improve 
the quality of our investigations and focus the discussion on “what failed” instead of “who failed”, identifying 
solutions that are addressing system improvements. 
 
We are also targeting shift leaders whose role in setting an example and transmitting knowledge is crucial to our 
safety strategy. In 2024, we launched a specific plan to ensure they attend training courses of high-risk activities 
(i.e. work at height) in the case one or more of their people has a certification in that subject. The objective is to 
increase their knowledge so that they can perform a better preventive activity when they are in the field 
supervising those activities. 
 
As part of our drive to empower shift leaders, we are also continuing the delivery of a “Positive Approach” 
training course to give them the tools they need to act as safety coaches for their teams. 
 
We are continually refining our training courses about high-risk activities (e.g., work at height, in confined spaces, 
crane and vehicle operation) for greater effectiveness, incorporating the lessons learned and examples coming 
from the events that occur worldwide.  
Additionally, we regularly enhance the quality and effectiveness of our communication routines with face-to-face 
meetings between shift leaders and shop-floor employees. These are opportunities to exchange clear, consistent, 
and relevant information on safety, quality, production, and other topics, as well receive feedback and 
suggestions for improvement.  
 
 

Annual Report 2024 
164 
Annual communication campaigns target best practices and highlight potential risks and hazards in the 
workplace. In 2024 we focused on a specific campaign to reinforce the importance of performing a preventive 
activity with quality, focusing on high risks and ensuring that the time we spend in the mill is effective in 
improving the level of safety. 
 
Effectiveness in risk reduction  
 
We are committed to reducing the occurrence of high severity incidents, which involves developing cross-site 
action plans following relevant events, and a comprehensive preventive program to leverage the hierarchy of risk 
controls.  
 
We consistently review our risk analyses at all sites, increasing operator involvement and the number of initiatives 
targeting high impact areas. Our safety objectives are supported by detailed plans implemented at each site and 
training and communication initiatives. The focus in on implementing robust solutions to reduce risks. 
 
We are also continuously reviewing the risks that could lead to catastrophic consequences, performing worldwide 
mapping and benchmarking in our sites and defining targeted investments to improve design and engineering at 
facilities, equipment maintenance, ensuring effective alarms and control points, and reinforcing procedures and 
training. 
 
Special task forces on critical risks such as cranes and vehicles are also continuing with the aim of sharing best 
practices and activities on these hazards.  
 
We are also employing a cross-site approach to share lessons learned from critical events to prevent them 
happening again. Actions include improving workplace conditions, documenting procedures, and training. 
Although progress is being made, we recognize the need to be more agile in implementing similar measures on a 
global scale. 
Contractor safety  
We include all contractors working at our sites in the Tenaris Safety Management System to ensure our 
prevention programs are truly effective.  
In 2024 we continued working on a specific project to improve HSE Contractors management, together with 
Exiros, our procurement company. The project focuses on making our selection process more robust, ensure 
adequate competence of the people performing the job, reinforce supervision during the execution phase and 
review our evaluation process ensuring the safety component is adequately considered. 
We are also strengthening our access control system to ensure contractors meet all the requirements before 
entering our site as well as better identifying the areas where high risk activities have been performed to intensify 
supervision and verification that all proper safety measures are in place. 
Whitin contractors, our main focus is on Tier 1 Service Sourcing Groups for which we also conduct a formal HSE 
audit to check the existence of a HSE system, and the level of development of such system.  
The Health Care Project - Supporting better health 
Tenaris’s comprehensive occupational health program enshrines the company’s commitment to providing a 
healthy workplace, whether in the office, mill or at home when remote working. 
The Health Care Project was launched as a preventive strategy to help our employees and their families to be in as 
good health as possible. In the last years, medical check-ups and follow-up have been held company wide as part 
of our drive to get employees to take responsibility for their own physical and mental well-being.  
The check-ups also yield data enabling Tenaris to identify and improve problems statistically common to certain 
groups and detect patterns for specific pathologies at regional level.  
This enables medical services to identify the most relevant physical examinations for each person and develop a 
personalized health management program.  
 

Annual Report 2024 
165 
While the check-up continues on a yearly base, we started to focus attention also on defining and consolidating a 
common set of company-supported health benefits aimed at encouraging physical activity, Nutrition, Anti-
Smoking programs and Mental Health, as part of a corporate well-being campaign have been rolled out at all 
locations. We are also defining ways to monitor adoption to adjust further according to the needs and 
preferences.  
Global recognition  
In 2023, we launched the “Tenaris Health and Safety Award” initiative to encourage local teams to contribute 
tried-and-tested schemes to improve health and safety aspects of specific processes. The Awards are organized as 
a contest, with the added incentive of presenting solutions at a global level, where the persons behind the 
solutions are appropriately recognized. 
 
The scheme is based on the ‘H&S Excellence Recognition’ done by worldsteel and the initiatives that are the 
winners of the ‘Tenaris Award’ are submitted to participate to that “contest”.  
We are proud that in 2024 we have been recognized for the second year in a row by worldsteel in the category of 
“Occupational safety” for an initiative developed in our mill in Dalmine, Italy.

Engaging with our communities 
 
Throughout our history, one of the core values intrinsic to Tenaris’s heritage has been the strong relationships it 
has forged with the communities where it operates. We are convinced that the sustainable growth of our 
industrial project can only be achieved in tandem with progress in the communities where we live and work. Our 
vision of community relations reflects the industrial values that have underpinned our activities for over 70 years.  
At Tenaris, our commitment to sustainable development is reflected in our ongoing engagement with local 
communities and their representatives and members. Our approach is embedded in our core values and daily 
activities, ensuring that sustainability is not a separate program but an intrinsic part of our operations. 
Moreover, the Compliance Line is one of our primary mechanisms for stakeholders to raise their concerns, 
including communities, and it is an internally established channel designed to ensure that all reports are handled 
appropriately. Our general approach to remediating our negative impacts when such cases are identified through 
the Compliance Line is described in “Sustainability Statement – Governance - Business Conduct – Compliance 
Line”.  
Our Actions 
 
Our community program reflects over seven decades of industrial tradition worldwide, with a special focus on 
Latin America. The principle guiding our work is that an industrial project like ours can only be sustainable if 
community and industry grow together. We believe that education is the key driver for individual and social 
progress, and that we can and must contribute to improving the quality and inclusiveness of education in our 
communities. 
We have seven strategic programs that are implemented locally to fit with the needs of each community where 
we operate, which are focused on education and culture. Our global education programs are named after 
Roberto Rocca, one of our founders, who believed that education plays a vital role in people’s development and 
that there must be synergy between industrial culture and technical education. 
In 2024, Tenaris invested $17.9 million in its community relations program, complemented by a $3 million

Educational Programs 
For all levels 
Our educational programs span the entire schooling cycle, from elementary to higher level, helping children to 
fulfill their potential and become active contributors to society. We are convinced that access to quality education 
leads to individual and collective well-being. Our programs are about developing 21st century skills, enabling those 
taking part to transform their own reality, always imbued with a strong sense of community. 
The Roberto Rocca Technical Schools Network, Roberto Rocca Technical Gene, the Roberto Rocca After School 
program and Roberto Rocca Scholarships are the four global initiatives supporting education in our communities.  
Roberto Rocca Technical Schools - Developing high standards of technical education  
The Roberto Rocca Technical Schools network aims to level the playing field and create equal opportunities for 
children to access technical education, offering scholarships to all students depending on their needs. The Roberto 
Rocca Schools also offer technical courses to other schools and people in the community. In 2023, the 
international organization T4 Education ranked the Argentine Roberto Rocca School among the ten most 
innovative schools in the world, singling out its educational environment and active learning model.  
Expanding the network  
The first Roberto Rocca Technical School opened in Campana, Argentina, in 2013 and today has 452 students. 
Originally built for 420 students, it was expanded in order to be able to receive 520 students. New intake rates 
rose from an initial ceiling of 60 to 72 in 2024. Another focus is on encouraging women to study STEM (science, 
technology, engineering, math) subjects: the percentage of female students at the Roberto Rocca Technical 
School has risen from 11% in the first admissions process in 2013 to nearly 42% in 2024. Roberto Rocca Schools 
network has spread to Mexico and is now expanding in Brazil through our sister company Ternium. 
 
Students achieve high math and technical levels and over 90% continue studying at university, in many cases 
being the first in their families to do so. The approach taken by the school is to offer quality education and equal 
opportunities reducing the initial gap between low and high-income entry-level students over the seven years of 
their schooling.

With the aim of promoting employability, the Roberto Rocca Technical School opened as Technical Training 
Center. During 2024, the proposal included technical courses such as Computer aided design and Cisco computer 
network analyst and Electrical assembler. The Roberto Rocca Technical School also partners with industrial 
automation companies FESTO and Siemens to certify students from other schools in Industry 4.0 knowledge and 
offers Math and Language courses for all elementary school-students about to begin high school. In 2024, the 
Roberto Rocca School trained over 1000 people from the local community. 
We believe that gifted and committed teachers are crucial to achieving academic excellence. The continuous 
training and performance evaluation of the educators of the Roberto Rocca Technical Schools allows us to ensure 
quality in the implementation of the educational model. In 2024, over 2,500 hours of training were provided for 
teachers and staff. We also evaluate our teachers using student feedback surveys, use of active teaching methods, 
quality of their classes and assessment by the schools’ authorities. 
Evaluations as a pillar of improvement 
The Roberto Rocca Technical Schools network plans its actions as part of a strategy of continuous improvement to 
enhance the quality of its education. It holds regular evaluations to benchmark the knowledge levels of its 
students.  
Regarding Mathematics and Spanish, the students take standardized tests to determine their level at the time of 
entry (Starting point) and at the end (End point) of their schooling. These tests not only demonstrate the level of 
academic excellence, but also that the school is effective in leveling up its students, neutralizing the effect of 
socioeconomic context. 
Roberto Rocca Technical School students also participate in the Math and Spanish tests held by the Austral 
University to evaluate standards at private schools of a medium-high socioeconomic context. In 2024, the results 
of the Roberto Rocca School students were above the average results, even considering the other schools 
assessed have students from better socioeconomic backgrounds. 
Every year, students, families, teachers and staff answer satisfaction surveys about school environment as a whole. 
In 2024, a total of 639 people answered to the survey. The favorable rating was about 81%.  
Roberto Rocca Technical Gene - Strengthening technical education  
Roberto Rocca Technical Gene contributes to bridge the gap between the knowledge and skills that students 
graduating from technical schools have compared with the industry needs. The program mainly offers technical 
trainings, industrial internships in our industry and modernization of school labs. Roberto Rocca Technical Gene is 
present in 24 schools in 8 countries, reaching over 6,400 students and teachers. 
In 2024, in Bergamo, Italy, the new headquarter of Fondazione Dalmine was inaugurated with 5 laboratories with 
cutting-edge equipment in robotics and automation, to offer a series of courses that strengthen the educational 
offer to technical schools. Through technical courses in collaboration with ABB, FESTO and Siemens, young 
people were able to acquire the skills necessary to face the challenges of industry 4.0.  
In 2024, also, over 200 students from technical schools in Bergamo, Campana, Pindamonhangaba, Veracruz and 
Zárate completed their training in pneumatics, electro pneumatics, hydraulics and automation, which we 
developed in partnership with FESTO and ABB; which enriches the technical qualifications of the participants and 
enhances their employability in the industry. 
In 2024, we opened our plants to 329 students from Campana, Pindamonhangaba, Bergamo, Veracruz and Zalău 
to perform their industrial internships. 
Trying to improve mathematics levels in Latin America, we designed 35 courses for teachers in the region, which 
we have made available through a digital platform. During 2024, over 2,300 students and teachers from three 
countries received these trainings. In Veracruz, Mexico, in the technical school ¨Conalep II¨, we have seen a 
sustained improvement in the math performance of its students: their results have increased by 8% over the last 
three years. During this period, teachers and students participated in the training provided by the Roberto Rocca 
Technical Gene program.

The Company has in place a Code of Conduct for Suppliers, which has been translated into ten languages and is 
made available to all personnel and suppliers. Furthermore, the Company adopted a Sustainable Sourcing Policy, 
which is intended to foster closer dialogue with suppliers and improve their awareness of sustainability concepts 
so that they can accompany Tenaris in meeting the standards required in its operations, providing support and 
guidance as needed. All third parties are required to meet internal standards governing ethical behavior, legal 
compliance, and health and safety responsibilities. 
Diligent and consistent compliance with the provisions of the Code of Conduct for Suppliers will be considered 
for selection, retention and evaluation of suppliers. Suppliers shall be responsible for applying the principles 
contemplated in the Code of Conduct for Suppliers even in the relationships with the sub-suppliers they work 
with to the extent they participate in any way in transactions or dealings with Tenaris.  
Under our Sustainable Sourcing Policy, we carry out a selection process to ensure that our suppliers meet the 
standards enshrined in our Code of Conduct and comply with applicable local laws and regulations. We expect all 
our partners in business to observe the same high standards we follow internally governing ethical behavior, legal 
compliance, and health, safety and environmental responsibilities.  
This Sustainable Sourcing Policy is in line with the principles set forth in the UN Sustainable Development Goals 
and the Worldsteel Sustainability Charter and complements our Code of Conduct, our Code of Conduct for 
Suppliers, our QHSE Policy, our Human Rights Policy and other related internal policies and procedures. 
All together, these policies create a robust framework for responsible supply chain management at Tenaris. We 
track the effectiveness of our policies through our supplier management processes and related actions and 
indicators, as described below.  
For more detailed information on these policies, please refer to “Sustainability Statement - Sustainability in Tenaris 
- Policies and procedures”. 
Preventing and remediating impacts 
 
Suppliers’ management processes are defined with a risk-based approach, in which different areas of the 
company are involved depending on the aspects covered, either defining the requirements on suppliers, carrying 
out the corresponding assessments or conducting the applicable controls. 
Our engagement approach with suppliers is embedded within our broader commitment to QHSE management 
systems. We recognize the importance of implementing our policies throughout our entire supply chain, from 
suppliers to end-users.  
The engagement with suppliers is done together with Exiros, our procurement company. Exiros is present in 19 
countries, offers a vast range of services and integral solutions for industrial clients within the Techint Group and 
in which Tenaris has shared ownership with its affiliate, Ternium.  
Exiros’s activities extend across the entire supply chain, from sourcing, hiring and management of suppliers, to 
inventory planning, logistics and import services. Leveraging on market knowledge and purchasing power, Exiros 
also supplies materials for different customers around the world through its trading company.  
Exiros quality management system is certified by ISO 9001 standard. In December 2024, Exiros had nearly 90,000 
registered suppliers, of which over 16,000 were active during the year, with 9,700 supplying Tenaris. 
Supplier registration 
Every new supplier willing to engage in a commercial relationship with Tenaris must go through a registration 
process, which guarantees that our suppliers commit to the standards outlined in our Code of Conduct for 
Suppliers and comply with applicable laws and regulations. The requirements are defined by Tenaris’s Business 
Conduct Compliance Officer (“BCCO”) and Compliance area, while the background check is carried out by Exiros. 
Considering a risk-based approach, each supplier is categorized by the risk associated, under which a general set 
of affidavits and controls regarding Human Rights and origin or relation with restricted persons or countries are 
coupled with particular requirements according to the category of materials or services to provide. Also, during 
the process, a background check is performed with a screening tool to detect non-disclosed red flags.  

Annual Report 2024

Due diligence process for high-risk suppliers 
The due diligence, part of Tenaris’ Business Conduct Compliance Program, consists of an integrity risk assessment 
process over a third party, applicable to suppliers that will represent or act on behalf of Tenaris before any 
governmental entity, including customs agents, permitting assistants, law firms, advisors, or commercial agents 
being susceptible to corruption risks. The due diligence is regulated by specific internal procedures, which demand 
additional assessment, controls, training and express commitments and it is performed with a determined 
frequency based on the entailed risk.  
BCCO continuous monitoring  
Tenaris has strengthened its controls by expanding training programs, conducting more thorough screenings, 
standardizing critical service contracts, and including ethics clauses in agreements with third parties. For more 
information on our Business Conduct Compliance Program and how relationships with third parties are managed, 
please refer to “Sustainability Statement - Governance-Business Conduct - Compliance Program”.  
Conflict minerals campaign 
Every year, Tenaris conducts a reasonable country of origin inquiry to determine whether its products contain 
conflict minerals originated in the Democratic Republic of the Congo or the adjoining countries subject to modern 
slavery risks. This process helps us make informed decisions regarding the purchase of products from our direct 
suppliers containing conflict minerals. Only a negligible portion of Tenaris products may contain conflict minerals, 
particularly from a specific ferroalloy or semi-finished products of certain steel grade. Every year, Tenaris files the 
Conflict Minerals Form to the SEC of the United States of America.  
The Compliance Line 
The Compliance Line is managed by the Company’s Internal Audit Department under the supervision of the 
Company’s audit committee. Complaints can lead to disciplinary actions, including dismissals and termination of 
commercial relationships. For further information, please refer to “Sustainability Statement - Governance-Business 
Conduct - Compliance Line”. 
Our Actions 
The risk of disruption in the supply chain, is a material topic given the conflicts and geopolitical unrest around the 
world, impacting how companies run their businesses. The need to build resilience into the supply chain and to 
have a diversified sourcing strategy is as strong as ever.  
In this context, Tenaris is devoting considerable resources to strengthening its supplier relationships, with a view 
to reducing transaction costs, as well as enhancing flexibility and fostering greater adaptability for more efficient 
problem-solving.  
We are committed to working with our suppliers to improve sustainable business practices, assisting them to 
identify risks and opportunities, providing training, sharing knowledge and raising awareness, and, in general, 
working together to improve the sustainability of our supply chain and our business.  
By deepening our approach to value-chain management, we are also extending existing policies implemented by 
our procurement company Exiros for a sharper focus on environmental performance. 
GHG Emissions - Scope 3 campaign 
In 2022 we started a CO2 emissions campaign with our suppliers, with the objective of assessing suppliers’ real 
emissions factors, which then are considered in Tenaris’s own emissions accountings. Following worldsteel 
methodology and international standards, nearly 60 suppliers from relevant raw materials categories have been 
assessed in 2024, including iron ore pellets, pig iron, ferroalloys and lime suppliers, among others.  
Sustainability assessment - Open-es Platform onboarding 
With the aim of having more knowledge on the value chain status regarding sustainability and to foster the 
development of sustainable practices within suppliers, we have invited a first set of approximately 40 suppliers to 
complete their assessment on the Open-es platform or to provide a similar sustainability assessment.  

Annual Report 2024 
179 
Conflict minerals campaign 
To manage our impacts, risks and opportunities related to workers in conflict minerals areas, we conduct an 
annual Conflict Minerals control campaign led by our compliance department. This campaign targets suppliers 
who provided raw materials or semi-finished steel products potentially containing conflict minerals, such as 
ferrotungsten and steel bars. Suppliers are required to answer questions regarding the presence of conflict 
minerals in the materials they supply to Tenaris and detail the origin of these raw materials.  
 
In 2023 we’ve identified and surveyed 45 Potential Conflict Minerals Suppliers, from which 100% have confirmed 
that none of the products supplied to Tenaris, including raw materials, contain conflict minerals originated from 
any of the covered countries. The 2024 campaign is under process, with 42 suppliers contacted. 
 
Quality management 
We have an annual audit plan to assess suppliers’ quality management systems, focused on our critical suppliers, 
regarding the quality of services and materials provided, as how such inputs impact the quality of Tenaris's final 
products. During 2024 we have audited 218 suppliers.  
 
Health, Safety and Environmental management 
Suppliers performing HSE high-risk activities inside Tenaris´s mills are required to have implemented an HSE 
management system based on international standards. As of the date of this report, we have audited and certified 
97% of our high-HSE risk active service suppliers. 
 
ProPymes Program 
Launched in December 2002, the ProPymes Program supports Small and Medium-sized Enterprises (“SMEs”) 
making up the value chain of Tenaris and its sister companies Ternium, Tecpetrol and Techint Engineering & 
Construction. The Program aimed to build an integrated ecosystem with the companies in the value chain by 
helping them grow, innovate and develop successful export strategies.  
 
Today, the Program works with 1,147 firms which have received technical assistance to train around 58,000 
employees, and over $94 million in credit support from the Techint Group. These firms have exported goods and 
services worth $273 million to other Group companies. In 2024, the Program provided 95,000 training hours.  
 
The 23rd ProPymes Seminar took place on December 12, 2024 at the Buenos Aires Convention Center, bringing 
together over 950 attendees, both in-person and virtual. The event featured representatives from SMEs within the 
Techint Group’s value chain in Argentina and included panels focused on competitiveness, innovation, technical 
education, and industrial development. 
 
ProPymes supports the Group’s community education program Technical Gene. In 2024, SMEs helped technical 
schools train 458 young people in workplace skills through on-the-job training.  
 
Payment practices 
Tenaris´s business model involves relying on an extensive network of suppliers, in markets with significant regional 
and country differences. We don´t categorize suppliers and therefore, don´t have different payment terms by 
category. Payment terms vary depending mainly on countries as well as from supplier to supplier.  
 
 

Annual Report 2024 
180 
 
In 2024, average invoice payment days across all accounts payable, was 39 days. The percentage of payments 
aligned with its payment term was 87%. Tenaris has no ongoing legal proceedings for late payment.

Commitment 
 
To build a corporate culture of transparency and integrity based on ethical behavior and compliance with the law. 
Objectives 
 
• 
Develop and oversee Tenaris’s strategy and risk management, taking into account financial, social, 
environmental, compliance and ethical considerations to ensure our long-term sustainability. 
 
Policies and Procedures 
 
We have implemented policies and procedures to manage and address impacts, risks, and opportunities on our 
employees related to ethics and compliance, health and safety, working conditions, and human rights. For a 
summary of our main policies and procedures, please see “Sustainability Statement - Sustainability in Tenaris - 
Policies and Procedures”. 
 
Code of Conduct and the Policy on Business Conduct 
 
Tenaris has significantly enhanced its policies and procedures to establish a comprehensive normative framework 
to prevent, detect, and mitigate bribery, corruption, and related risks, by outlining anti-bribery and anti-corruption 
controls and several risk mitigation measures. The foundation of this normative framework is the Code of 
Conduct and the Policy on Business Conduct, which explicitly prohibit any actions that could contravene 
applicable anti-corruption and anti-bribery laws. 
The Code of Conduct was initially approved by the Company’s Board of Directors in 2003. It has been reviewed 
regularly, with revisions approved by the Company’s board of directors. The most recent edition was released in 
2024. The Code of Conduct is accessible to the public and on Tenaris’s intranet, and is available in the local 
languages of many locations where Tenaris operates. The Code of Conduct is applicable to all Company 
personnel and extends to any entities under the Company’s control and any third-party representatives.  
The Policy on Business Conduct, initially approved in 2009, outlines the Company's anti-corruption and anti-
bribery rules to ensure ethical and compliant conduct in all business relationships and interactions with 
government agencies, state-owned enterprises, private-sector entities, and their representatives. This Policy on 
Business Conduct encompasses provisions regarding compliance training, due diligence in hiring third-party 
representatives, prohibited payments, identifying red flags in business relationships, monitoring compliance, 
internal investigation procedures, and disciplinary actions. The Policy on Business Conduct is dynamic and 
undergoes regular reviews to ensure compliance with international standards and best practices, incorporating 
lessons learned since its inception. Like the Code of Conduct, the Policy on Business Conduct has been translated 
into the local languages of many regions where Tenaris operates. The most recent version of the Policy on 
Business Conduct was released in March 2024.  
 

Annual Report 2024

Code of Conduct for Suppliers  
 
The company has adopted a Code of Conduct for Suppliers to ensure that Tenaris’s suppliers adhere to high 
standards of integrity, transparency, and compliance with laws in all business dealings. For more information 
about this Code of Conduct for Suppliers and how the Company manages its relationship with all its suppliers, 
please refer to “Sustainability Statement - Social - Our Value Chain”. 
Accounting Provisions  
 
The Company adopted specific policies and procedures to ensure compliance with the accounting provisions of 
relevant anti-corruption laws, and the accuracy of the books and records. For example, the Financial Controls and 
Accounting Policy, most recently reviewed in 2024, aims to minimize the risk of inaccuracies in accounting entries, 
due to error or fraud, bribery, or corruption. The Company’s Books and Records Assurance Policy outlines strict 
rules and guidelines for the accurate and timely recording of all transactions. Additionally, the Document 
Retention Policy adheres to best practices and international laws on the maintenance of records and historical 
archives for legal, commercial and compliance purposes. Furthermore, the Code of Ethics for Senior Financial 
Officers, which applies to the principal executive, financial, and accounting officers, as well as controllers and 
similar roles, aims to prevent misconduct and ensure these officers uphold personal and professional integrity, 
comply with the law, and follow the Company's Code of Conduct and other policies. The Company has also 
adopted a Conflict of Interest and Non-Competition Policy to address risks associated with the Company’s 
business interactions with others, which was last updated in 2022.

Compliance Culture 
Tenaris recognizes that extensive training and dissemination are essential for successfully fostering a compliance 
culture. Consequently, Tenaris has developed a comprehensive training program for all employees. The training 
comprises a blend of in-person and online sessions, including live webinars on business ethics, and business 
conduct policies and procedures. To enhance the effectiveness and retention of information, the training has 
transitioned from traditional classroom settings to workshops that integrate theory and practice. These workshops 
include case studies, guest professors and speakers, quizzes, surveys, and interactive activities. Additionally, the 
training incorporates videos with practical scenarios. 
Training is based on employees' functional roles, position risk assessments, and their exposure to customers or 
governmental entities. Additionally, the Company conducts onboarding meetings for newly promoted senior 
employees, focused on those who will interact with customers or government entities in high-risk countries. 
Regarding compliance divulgation, the Company has implemented a multidisciplinary approach to its compliance 
communications strategy, fostering a comprehensive Company-wide culture of compliance. The compliance 
function employs various communication channels to reinforce and complement training efforts, thereby ensuring 
continuous employee engagement and awareness of best practices. For example, the Company uses newsletters, 
brochures, fictional case studies, targeted emails, billboards in office locations and manufacturing sites, flyers, 
reminders, and specific campaigns focused on policies and procedures, internal controls and red flags awareness. 
These approaches communicated to both employees and management underscore the significance of compliance 
and provide practical examples of potential compliance issues. 
In 2024, the Tenaris Employees Survey received positive responses about how the Company communicates 
expectations for ethical behavior and integrity compliance. From 23 main categories, the statement related to 
Compliance was the most answered with a positive response from all the employees with 86% of very positive 
answers (rank 4 & 5 on a scale from 1 to 5). 
Compliance culture is consistently emphasized in leadership communications and interactions with the compliance 
function, with senior management actively requesting for advice, participating in town halls, management 
meetings, and training sessions.  
Additionally, the Company regularly uses diverse communication channels to distribute policy updates, raise 
awareness on controls, refresh business conduct compliance expectations, and communicate activities and lessons 
learned during visits to Tenaris’s facilities or commercial offices.

Business Conduct Compliance Program 
Tenaris adhered to the United Nations Global Compact initiative, which promotes corporate sustainability by 
formalizing its commitment to operate under the human rights, labor, environmental and anti-corruption 
principles outlined by the Global Compact. Tenaris’s Business Conduct Compliance Program is aligned with anti-
bribery and anti-corruption laws and regulations, including the U.S. Foreign Corrupt Practices Act (“FCPA”), the 
UK Bribery Act, and the OECD Convention for Combating Bribery of Foreign Public Officials in International 
Business Transactions. 
The Company has implemented a comprehensive set of activities and compliance measures designed to prevent, 
detect, and address instances of corruption and bribery. These initiatives are integrated into its Business Conduct 
Compliance Program, which encompasses the following elements: 
• 
Policies and Procedures: The Company issues or updates its normative framework to define 
comprehensive business conduct rules, processes, standards, and controls. These policies and procedures 
are designed to prevent, detect, and mitigate bribery, corruption, and related risks. Additionally, these 
documents specify the responsibilities of each employee in implementing them. During 2023 a new 
edition of the Code and Policy on Business Conduct was approved by the Company’s board of directors. 
• 
Communication and Training: The Company consistently communicates its policies and procedures to 
personnel. It ensures they are kept up to date with compliance news, reminders and training sessions, 
fostering a clear understanding of the Company's ethical standards and compliance culture, which 
employees are required to adhere to. During 2024, the Company issued 66 communications pieces 
relevant to business conduct. Regarding business conduct compliance training, during 2024 the Company 
conducted 113 in person or live training sessions, and 3,934 employees of 28 countries, where Tenaris 
operates. In addition, 8,962 employees completed customized e-learnings on the Policy on Business 
Conduct. Additionally, third parties with higher exposure are mandated to complete specialized 
compliance training. These training sessions emphasize business and ethics commitments, reinforced by 
the Company's messaging on expected behavior, obligations, responsibilities, and consequences of non-
compliance. During 2024, the Company on-line trained 523 non-Tenaris employees of 144 third parties 
and conducted in-person training to various employees of third-party companies, generally in high-risk 
countries. 
• 
Risk Assessment: The Risk Assessment on business conduct involves regularly evaluating geographical 
locations, functions, business activities, and interactions or transactions with specific third parties that 
may expose the Company to higher bribery and corruption risks. 
• 
Third Parties Risk Management: The Company assesses third parties to identify potential integrity risks 
they may pose on Tenaris. The Company has implemented a risk-based due diligence process, which 
includes compliance commitments, including adherence to legal and regulatory standards, screenings, 
and standard clauses. During 2024, the Company completed 146 enhanced due diligence on higher 
exposed third parties. 
• 
Guidance and Advice: The office of the Business Conduct Compliance Officer (“BCCO”) regularly 
provides employees with guidance and advice on anti-corruption and anti-bribery compliance, supporting 
them in their daily activities and decision-making processes. During 2024, the compliance function 
responded to 732 requests for compliance advice. 
• 
Compliance Monitoring: The Company regularly reviews key processes, including due diligence, 
screenings, business justification, payment rationality, red flag resolution, completion of mitigation 
measures, and supporting documentation provided by functions that sponsor a transaction or 
engagement of a third party. The objective is to ensure high-quality integrity assessments, preventing 
transactions or business relationships with third parties who may deviate from standards, have negative 
historical records, or lack necessary credentials for their assigned tasks. During 2024, the Compliance 
function conducted 618 monitoring activities, 435 concerning high-risk countries; none dealt with critical 
or material concerns. The Compliance function communicated its observations and proposed remediation 
measures for management to implement, and reported indicators, including red flags and mitigations, to 
the audit committee of the board of directors.  
 

Annual Report 2024

• 
Reporting: The BCCO reports regularly to the audit committee of the board of directors and the CEO on 
risks, remediation efforts, program indicators, and regulatory trends. The BCCO can also escalate critical 
issues requiring top-level action or investigation. 
• 
Key Business Conduct Enhancements. During the years of the Business Conduct Compliance Program, 
the Company has developed several responses and process improvements, including updates on the 
Code of Conduct, the Policy of Business Conduct and the Policy of Conflict of Interests for Employees, 
incorporating the Key Principles of the Policy on Business Conduct for Third Parties and the new 
Compliance Line platform, coordinating compliance in-person and online re-training for employees and 
intermediaries, regularizing compliance measures on suppliers with a risk-based approach, standardizing 
background checks methodology, business ethics clauses and certain types of contracts, certifying 
compliance and developing the “BCCO Office Responds Platform” for compliance guidance and advising 
to employees, among others.

Business Conduct Risk Management 
Tenaris recognizes that maintaining appropriate internal controls requires the identification of structural and/or 
incident-specific gaps through rigorous testing and analysis. The principal mechanism for evaluating bribery and 
corruption risks is the Company’s Business Conduct Risk Assessment. 
Certain functions may be more susceptible to risks than others. Those functions include, by way of example, 
individuals who frequently interact with customers, government bodies or state-owned companies; those who 
manage relationships with third parties; those working in countries or regions identified as high-risk in terms of 
corruption; or those involved in business development, new projects, new markets, appointing representatives or 
business associates in high-risk areas, and mergers and acquisitions. 
The Risk Assessment identifies geographical locations, areas and activities that expose the Company to potential 
bribery and corruption risks. It analyzes and assesses those risks, and it evaluates the suitability and effectiveness 
of the Company’s current controls considering those risks. In addition, the Company’s compliance function 
analyzes each specific job function’s exposure to risks by considering several factors, including the employee’s 
level within the Company and scope of responsibilities. Based on the Risk Assessment, the Compliance function 
designs, develops, and implements appropriate existing or additional risk-based controls and monitoring activities 
to mitigate the identified risks, as well as tailors the priorities of the Company’s Compliance function. In particular, 
the Risk Assessment defines and informs the Compliance Officer’s agenda for business conduct monitoring plans, 
training plans, communications and certification campaigns, process improvements, as well as plans for future 
reviews of and updates to the Company’s policies and procedures. 
The Risk Assessments on bribery and corruption are performed regularly, but certain events may also trigger a 
specific assessment that occurs sooner than the next Risk Assessment. For example, new projects, entries into new 
markets, new representatives in high-risk markets, substantial reorganizations, changes of management and 
staffing, and mergers and acquisitions can all give rise to an immediate review of the relevant Company 
compliance policies and activities to addressing such events.  
 

Annual Report 2024

Monitoring, Investigations, Audit Reviews and Compliance Assurance 
The Business Conduct Compliance Office conducts various forms of business conduct compliance monitoring, 
including third parties and transactions due diligence controls, enhanced background checks, and identifying and 
assessing potential red flags, and addressing red flags that may require an investigation by the Internal Audit 
Department, supported by the Legal Department or external advisors.  
Whenever necessary, the BCCO, with assistance from the Internal Audit Department and Tenaris Legal Services, 
promptly investigates all reports or complaints regarding violations of the Policy on Business Conduct and related 
procedures. Both, the BCCO and the Internal Audit Department are provided with adequate resources and receive 
reasonable cooperation from company personnel for such investigations.  
The Internal Audit Department executed audits and follow-up reviews specifically related to compliance with the 
Policy on Business Conduct and related procedures. These reviews were carried out in accordance with an annual 
audit plan. The methodology applied to define the annual audit plan is aligned with the international standards of 
the profession and best practices, which include periodic reviews to ensure an adequate focus on emerging risks, 
changes in business strategies/processes, and/or acquisitions that may occur during the year. The audit committee 
received quarterly updates on its execution.  
The internal control compliance area coordinated and verified the Company’s activities within an adequate 
internal control framework, ensuring compliance with internal and external audit requirements, implementing 
improvements or remediating deviations. In addition, the internal control compliance area is responsible for 
monitoring internal control risk situations, ensuring compliance with standards, and updating and disseminating 
of applicable control framework. It ensures continuous monitoring of internal control risk situations through the 
verification of compliance with internal and external audits. The area also conducts annual SOX tests on behalf of 
management to support the required certifications. 
Disciplinary Measures  
 
The Company takes violations of its policies and procedures seriously. When an investigation concludes that the 
applicable Company policy and/or applicable law have been violated, the BCCO is alerted. The Internal Audit 
Department evaluates the scope and specifics of the violation and provides recommendations for corrective 
measures. The BCCO shall determine the appropriate disciplinary measures to be taken, if any, considering the 
nature and seriousness of the violation, in consultation with the human resources and legal departments, and the 
supervisor(s) of any involved employee(s). Upon identifying a policy violation, disciplinary actions may range from 
warnings, compensation reductions, or termination of employees or contractors engagement for serious 
infractions of Company policies and procedures and/or law. After the BCCO determines and approves the 
appropriate disciplinary measures, the regional manager for the affected region collaborates with the BCCO to 
ensure that such disciplinary measures are implemented.

Compliance Line 
The Compliance Line is a multi-faceted reporting system that allows employees and third parties (including 
customers, suppliers, community members and other interested parties) to make reports telephonically (through a 
toll-free telephone line available in most countries where Tenaris operates), electronically (through a web page 
(https://www.bkms-system.com/Tenaris), QR Code, mobile device, or email (auditoria_responde@tenaris.com or 
audit_inquiries@tenaris.com)), or by direct communication with the Company’s audit function.  
This confidential communication channel is available 24/7/365. Shareholders, investors and other interested 
parties have an exclusive channel called the “Shareholder's Compliance Line” to communicate their concerns 
related to financial statements or internal control over financial reporting. It is a web-based form 
(https://ir.tenaris.com/corporate-governance/shareholder-compliance-line) that, once submitted, is sent directly to 
the members of the Company’s audit committee and the Chief Audit Executive. 
Reporting options are available in eleven different languages, ensuring accessibility for a diverse user base, and 
the system is designed to be intuitive and user-friendly. This system integrates advanced technology to enable the 
Company to receive and manage complaints in line with current best practices and regulatory requirements.  
The Compliance Line is managed by the Internal Audit Department under direct supervision of the audit 
committee. All reports received through the Compliance Line system are confidential and access to these reports 
is heavily restricted to ensure that such information is appropriately protected and to reduce the risk of retaliation 
against reporting individuals.  
All reports received through the Compliance Line are processed, administered and investigated by the Internal 
Audit Department, which may request assistance from other departments or areas as necessary. All reports shall 
be handled to ensure objective, independent, unbiased, and fair treatment of individuals and of any information 
received or collected and processed during investigations.  
In particular, the Ethics and Fraud Audit Department within the Internal Audit Department is responsible for 
reviewing and keeping record of all the complaints received through any of the access channels, immediately 
notifying the Chief Audit Executive about high-impact complaints to determine the appropriate investigation 
steps, defining and approving the investigation work program, conducting the investigation or ensuring 
coordination with other departments concerned, assessing the reasonableness of any remedial or other action 
plans proposed by the management, preparing quarterly summaries of closed and ongoing investigations to the 
Chief Audit Executive and to the Company’s audit committee, among others. 
 
Channel Availability 
 
The Company has enhanced its comprehensive reporting system to facilitate confidential and anonymous 
reporting by employees and third parties of any actual or suspected violations of the Code of Conduct, other 
policies or applicable laws, as well as any other improper activities. The Company has established multiple 
mechanisms for reporting and tracking potential violations through its Compliance Line, which was last upgraded 
in February 2022. 
 
The global communication campaign to promote the channel includes articles and digital banners in TenarisToday 
(intranet), mill newspapers publications, communications via WhatsApp and the HR App, e-mails, social media 
posts, screen savers, posters, roll-up banners, tent cards, signs and videos displayed on screens in offices and 
facilities. 
 
Additionally, both in-person and online trainings sessions on the Code of Conduct and business ethics are 
provided to employees, which incorporate a module on the Compliance Line. The Internal Audit Department 
delivers various learning activities focused on business ethics, designed to ensure employees understand and 
adhere to the Company’s Code of Conduct. These courses cover key topics related to policies and procedures in 
integrity and transparency, internal controls and fraud prevention. Employees also learn how to identify potential 
violations to the Code of Conduct and the different channels available to report them through the Compliance 
Line.  
 

Annual Report 2024 
189 
The training catalogue includes mandatory e-learning on the Code of Conduct, participation in global programs 
such as Tenaris University Induction Camp and Management Development Program, local sessions on business 
ethics for white collars and courses on the Code of Conduct for shop floor employees. 
 
For stakeholders, the Compliance Line is promoted on Tenaris web page, invoices and trainings sessions on the 
Code of Conduct for certain vendors, such as scrap suppliers. Furthermore, Tenaris Standard Terms and 
Conditions for Suppliers include a provision encouraging them to report any irregularity or violation of the Code 
of Conduct through the designated reporting link. This clause serves as a reminder to all parties of the 
Compliance Line’s availability for reporting any violations of Company policy or law, ensuring transparency and 
accountability. 
 
Cases Management  
 
Upon completion of any investigation process, the management of the areas involved propose action plans, which 
are evaluated for reasonableness by the Internal Audit Department. Upon coordination and agreement with the 
Internal Audit Department, the area involved promptly implements remedial actions, which vary according to the 
type of violation committed. These may include employees’ disciplinary actions (dismissal, suspension, written or 
verbal warning, impact on performance evaluation, specific training assignment), process and control 
improvement, termination of business relationship, exclusion from our facilities, or sanctions to contractor’s 
personnel, non-conformity issued to supplier, financial claim to supplier, impact on supplier’s evaluation, legal 
claim, among others.  
 
In response to the growing number of workplace environment reports over the total received (58% in 2024), the 
Human Resources Department has launched a workshop on work environment in various countries, which 
includes a module on the Compliance Line to further support the promotion of a respectful and inclusive 
workplace culture.  
 
Protection of Whistleblowers 
 
We protect whistleblowers through several measures designed to ensure confidentiality, prevent retaliation, and 
promote a culture of compliance and ethical behavior. The Company has adopted robust policies and procedures 
to protect whistleblowers and other reporting employees from any form of retaliation. 
 
The Code of Conduct expressly prohibits retaliation against individuals who raise any issue, report any potential 
violation, or participate in an investigation, and allows them to file anonymous reports. However, the Company 
encourages whistleblowers to identify themselves or provide contact information considering that the ability to 
interact with whistleblowers increases the effectiveness and efficiency of investigations. 
 
Any measures adopted by the Company as a result of a complaint investigation ensure equitable and impartial 
treatment of the personnel and third parties involved. The Company does not tolerate any harassment, 
discrimination, punitive actions, or retaliation against individuals who seek advice, raise concerns, report a breach 
or suspected breach, or potential violations in good faith. Any complaint regarding punitive or retaliatory actions 
is promptly investigated by the Internal Audit Department and appropriate remedial and/or disciplinary measures 
are taken if the investigation verifies any alleged retaliation or punitive action. 
 
Definitions regarding whistleblower protection are included in Tenaris’s Anti-Fraud Policy. 
Effectiveness of the Channel 
 
The Internal Audit Department acknowledges receipt of all reports received through the Compliance Line and 
provides feedback on each report to the relevant reporting person within a reasonable timeframe, in accordance 
with the provisions contemplated in applicable laws and regulations in each jurisdiction. 
Notwithstanding the above, Tenaris is not required to disclose details pertaining to specific individuals or any 
information that may compromise an investigation. The scope and content of the feedback is defined on a case-
by-case basis by the Internal Audit Department. In all cases, feedback considers the nature of the facts under 
investigation, the need to maintain confidentiality of relevant information, the requirement to ensure safe 
deployment of prospective investigation measures and the protection of the rights of any individuals mentioned or 
involved in the report and/or the investigation.  
 

Annual Report 2024 
190 
The number of complaints reported during 2024 has significantly increased compared to complaints received in 
2023, continuing the trend from 2022, which evidences the effectiveness of the Compliance Line and is mainly 
attributable to the implementation of a new, enhanced compliance line system in 2022, which facilitates the 
reporting of violations. Expanded training programs and communication campaigns to encourage the use of this 
channel have also contributed to this increase, in addition to the headcount increase. Another evidence of the 
effectiveness of the channel is the substantiation rate, which has remained stable in the last years (around 50 %). 
Incidents of alleged bribery 
 
In response to the undertakings adopted in connection with the settlement with the SEC relating to alleged 
improper payments in Brazil prior to 2014, Tenaris: (i) conducted an initial review of its anti-corruption policies 
and submitting an initial report; (ii) submitted periodic reports updating the SEC on the status of Tenaris’s FCPA 
and anti-corruption related remediation and compliance measures; (iii) conducted a final review of anti-corruption 
compliance programs and (iv) submitted a final certification of compliance with its undertakings in July 2024. For 
further information see note 27 “Contingencies, commitments and restrictions to the distribution of profits- 
Contingencies - Petrobras related proceedings and claims” to our consolidated financial statements included in 
this annual report.

Human Rights 
Tenaris is committed to conducting all its operations in a manner consistent with human rights principles, 
ensuring the respect for fundamental rights and dignity of every individual involved.  
 
Tenaris’s Human Rights Policy was adopted in 2009; it was reviewed in 2018 and more recently updated in March 
2022. This policy states that Tenaris will comply with the Universal Declaration of Human Rights, the principles 
articulated in the International Labour Organization’s Declaration of Fundamental Principles and Rights at Work, 
the United Nations Global Compact, and all applicable human rights laws and regulations in its operating 
jurisdictions. Key contents of the policy include: 
 
• 
Respect for human freedom and dignity: Tenaris prohibits child labor, forced or compulsory labor, slavery, 
servitude, cruel, inhuman, or degrading treatment, and discrimination. 
• 
Scope: The policy applies to Tenaris, its directors, officers, employees, joint ventures controlled by Tenaris, 
and their directors, officers, or employees. It also applies to Tenaris’s providers, suppliers, and third-party 
collaborators. 
• 
General standards and principles: All Tenaris employees, providers, suppliers, and third-party collaborators 
must be treated with dignity and equality. Tenaris promotes diversity and rejects any type of harassment 
or discrimination based on gender, sexual orientation, ethnic origin, color, age, religion, or political 
opinion. 
• 
Commitment to a safe work environment: Tenaris opposes forced, child, or compulsory labor and will not 
tolerate slavery and servitude in any form. The company is committed to a work environment free of 
violence, harassment, abusive treatment, or exploitation. 
 
The Company’s Code of Conduct contains a specific chapter, called "Workplace Environment," which describes 
the obligations of employees and third parties and summarizes the principles of international instruments: "...We 
support the elimination of all forms of discrimination, illegal, forced or compulsory labor, slavery or servitude, in 
particular child labor. Discrimination, illegal, forced or compulsory labor, slavery or servitude will not be tolerated 
at Tenaris. All Tenaris's suppliers and contractors are expected to comply with these principles." 
Tenaris is also subject to the 2015 UK Modern Slavery Act and has implemented a modern slavery due diligence 
review to assess commitment and compliance by its suppliers, as well as targeted training for employees 
performing tasks related to human rights and modern slavery issues.  
The application of the international standards is also reflected in Tenaris's Sustainable Sourcing Policy, which in 
section III (3) states “maintain a work environment that is respectful of the fundamental rights and dignity of 
people, free of violence, harassment, abusive treatment or exploitation”. The Sustainable Sourcing Policy applies 
to third parties and sets main expectations towards Tenaris's supply chain. In addition, the Code of Conduct for 
Suppliers, based on United Nations recommendations, has a specific chapter on “Labor and Human Rights”. The 
Code of Conduct for Suppliers applies to all the Company’s suppliers and must be accepted as a condition for 
entering into any agreement to provide goods or services to Tenaris.  
As part of the risk assessment of suppliers, commercial intermediaries, representatives and other third-party 
contractors, the Company has adopted a due diligence review to verify that third- party contractors comply with 
essential human rights regulations and have not infringed any applicable laws regarding slavery, forced or child 
labor. Tenaris (i) included in the general terms and conditions for the purchase of goods and services, a 
commitment by third-party contractors to comply with applicable laws, rules and regulations on human rights, 
including a prohibition of all forms of slavery, forced labor or child labor; and (ii) implemented a Code of Conduct 
for Suppliers based on United Nations recommendations, which contemplates a specific section concerning 
“Labor and Human Rights”. 
Tenaris has developed a targeted training course to enhance understanding of key laws, regulations, and risks 
affecting its operations and supply chain. The course focuses on raising awareness among procurement teams 
about supplier due diligence, educating employees on applicable standards and regulations, highlighting risks of 
non-compliance, and emphasizing the strategic role of Human Resources in enforcing policies and procedures. 
The goal is to ensure a healthy, sustainable, and compliant supply chain.  
 

Annual Report 2024 
192 
On April 25, 2024, the board of directors approved the Company’s annual Modern Slavery Statement, which 
describes how the Company monitors itself and its suppliers. Tenaris’s Human Resources Department conducts an 
internal survey process involving all regional Human Resources Senior Directors to assess specific human resources 
practices. Each Human Resources Director assessed Tenaris’s compliance with key human rights and modern 
slavery concerns, including, without limitation (i) minimum age required for employment; (ii) use of migrant 
workers; (iii) payment of recruitment fees; and (iv) the right to leave the job. Through this assessment process, it 
was concluded that no illegal or illegitimate practices were detected that would lead to a violation of human 
rights, labour or modern slavery laws and regulations applicable to Tenaris.  
To date, Tenaris has not experienced any cases of forced labour or child labour and thus has not had to take any 
corrective actions in such sense.  
Any infringement or violation of any applicable law or provision of the Code of Conduct (no matter if informed 
through the Compliance Line or through any other means) shall be subject to investigation and remediation in 
accordance with (i) applicable laws and (ii) the general principles contemplated in the Compliance Line Procedure 
(including the need to involve concerned areas and departments in the Company, respect privacy, rights, intimacy 
and identity of the victim, allow the accused or suspected employee to the rights of defense afforded by 
applicable laws, respect rules concerning confidentiality and due process). 
For reports not channeled through the Compliance Line (e.g., made directly to a Tenaris officer or received by any 
person in Tenaris), the provisions of the Compliance Line Procedure and the general rules in Tenaris´s Code of 
Conduct, will apply. Such reports will be directed to the Internal Audit Department, which shall request assistance 
from relevant areas concerned to review the matter and implement investigation and disciplinary procedures, as 
necessary. 
In regards of any request or formal inquiry from public authorities, Tenaris is prepared to fully assist governmental 
agencies through its experts and specialized departments, including the Communications Department and the 
Investor Relations Team, among others. The Code of Conduct includes a dedicated section on Public 
Communications, emphasizing cooperative, diligent, and appropriate interactions with agencies and authorities. 
In addition, Tenaris has adopted a procedure to ensure appropriate identification, evaluation, disclosure and 
recognition of contingent liabilities and provisions resulting from legal claims in accordance with IFRS 
requirements, enabling compliance with the duties and obligations of all parties involved. The procedure describes 
the responsibilities, criteria and steps to be carried out for purposes of appropriate disclosure and/or recognition 
of contingent liabilities and provisions resulting from legal claims involving Tenaris or its subsidiaries in each 
company’s individual financial statements and/or in Tenaris’s consolidated financial statements in accordance with 
IFRS requirements.

Annexes 
Annex I: Sustainability Statement Accounting Policies 
The principal accounting policies applied in the preparation of this sustainability statement are set out below. 
These policies have been consistently applied to all the years presented, unless otherwise stated. 
While the EU CSRD has not been transposed into national law by the Grand Duchy of Luxembourg and, 
therefore, the Company is not subject to CSRD reporting requirements, this sustainability statement has been 
prepared with reference to the ESRS as a framework, as issued by the EFRAG. This report also takes into account 
the reporting standards established by GHG Protocol and worldsteel, and the goals of the UN Global Compact. 
The information has been prepared on a consolidated basis, including data from the entire global operations. This 
scope covers all subsidiaries and associated companies where Tenaris has operational control, unless stated 
otherwise in this statement. It encompasses all operational regions, reflecting the company's global presence and 
its varied impact across different geographical locations. It incorporates data from the consolidated financial 
statements and operational metrics from all relevant business units. The scope of this sustainability statement is 
the same as the one for our financial statements, except for those production sites that were not considered 
material due to their low level of operation during the year, or any other case explicitly described in this 
statement. 
Tenaris covers its entire value chain, considering upstream and downstream activities as well as own operations. 
The materiality assessment of impacts, risks and opportunities is mainly focused on the oil and gas industry for the 
downstream value chain, due to its weight in total sales (89%). Tenaris is also providing products and services to 
industrial, mechanical, automotive and low carbon energy industries. Our Policies and actions extend to the value 
chain, especially in the upstream where Tenaris has more control over business activities.  
Tenaris defines short term in the field of risk management to be one-year, medium term up to five years, and long 
term over five years, hence consistent with the definition that the ESRS 1 section 6.4 Definition of short-, medium- 
and long-term for reporting purposes is providing. 
Our Health, Safety and Environment, and Quality Management systems are designed according to the latest 
versions of the ISO 14001, ISO 45001 and ISO 9001 standards. 
Rounding 
Certain monetary amounts, percentages and other figures included in this sustainability statement have been 
subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be the arithmetic 
aggregate of the figures preceding them, and figures expressed as percentages in the text may not total 100% or, 
as applicable, when aggregated, may not be the arithmetic aggregate of the percentages preceding them. 
Environment 
GHG Emissions 
To calculate or measure our GHG emissions, we employ the following methodologies, significant assumptions, 
and emissions factors:  
Methodologies:  
 
• 
Methodology used: GHG Protocol is the preferred methodology for the calculation; also, Tenaris considers 
World Steel Association CO2 methodology for the steel sector. 
• 
Presented figures and values for GHG Emissions in this sustainability statement do not include oilfield services 
unless otherwise stated. 
• 
Fuel-based Method: This method is used to calculate emissions based on the type and amount of fuel 
consumed.  
• 
Distance-based Method: This method calculates emissions based on the distance traveled by transportation 
modes (truck, train, vessels, etc.).  
 

Annual Report 2024 
194 
Major Sources of Emissions:  
 
• 
Electricity consumption related to EAF for steel production and pipe rolling for seamless production (Scope 2). 
• 
Natural gas use for power generation, direct reduction plant and furnaces for pipe rolling and heat treatment 
(Scope 1). 
• 
Raw materials for steel production and steel sourced externally (Scope 3). 
• 
For oilfield services, major source of emissions is the fuel used to power equipment (Scope 1). 
 
Emissions Factors:  
 
• 
Emissions factors are selected following the GHG Protocol guidelines. They may come directly from suppliers 
of energy and materials, or trusted databases or worldsteel methodology. 
• 
Emission factors for transportation fuel consumption are from the Global Logistics Emissions Council 
(“GLEC”) Framework. 
 
Reasons for Choosing These Methods:  
• 
GHG Protocol and worldsteel methodologies are well known and trusted sources for GHG emissions 
calculations and also widely applied in the steel sector. Moreover, the methodology for worldsteel data 
collection was used as the basis for the now published international standard ISO 14404:2013 - calculation 
method of carbon dioxide emission intensity from iron and steel production. 
• 
The fuel-based and distance-based methods provide a comprehensive and accurate representation of our 
emissions by considering both the type of fuel used and the distances traveled.  
• 
These methods align with industry standards and guidelines, ensuring consistency and comparability in our 
reporting.  
CO2 emissions intensity  
The intensity figure is expressed as tons of CO2-equivalent per ton of processed steel, which includes both 
internally produced steel and acquired steel that is processed at our sites. 
Additionally, we also disclose intensity per revenue.  
The Scope 2 emissions are calculated using both, the market-based approach and the location-based approach. 
Methodology use for CO2-eq calculation 
We use the GHG protocol to report our emissions. 
Our emissions reporting applies to all tubular production sites, including sites with integrated steelmaking 
facilities, rolling mills and finishing facilities for both seamless and welded pipes. 
The GHG protocol guides annual inventory-taking according to the “Operational control approach”. This means 
that the scope of accounting includes all Tenaris steel and tube production sites where Tenaris has operational 
control. A site’s emissions may be excluded if its production level is under 10,000 tons in the reporting year. A 
site’s emissions will also be excluded if it is not operative for at least nine months of the reporting year.  
The intensity value for Tenaris’s steel processes does not include emissions from Tenaris’s oilfield services 
operations which are reported separately on a gross basis. 
The base year taken is 2018. Scopes 1, 2 and 3 reporting follows the GHG protocol definitions. As Scope 3 
reporting is voluntary, relevant categories will be added and may change over time, increasing the number of 
categories included.  
 

Annual Report 2024 
195 
Changes in outputs from different sites owned by Tenaris and included in its operational control boundary do not 
entail a need to modify calculations over time and are not included in the base year.  
Emission factors are selected in accordance with the GHG Protocol Standard, in order of priority: supplier-specific, 
local emission factors, regional emission factors, and emission factors published by a recognized international 
entity (for example, worldsteel, the IPCC or IEA).  
The Scope 2 market-based approach takes into account the emissions factor of electricity with contracts, the 
method selected by Tenaris to calculate its emissions and intensity. There are countries where residual mix 
information is available and reliable for unclaimed electricity. In this case, the emissions factor will be applied to 
purchased electricity. 
Intensity is expressed as ton CO2-eq/ton processed steel, which includes steel cast and produced internally at 
Tenaris sites and the acquisition of steel bars, coils and plates that are processed at any of our sites to produce 
seamless and welded pipe. Intensity refers to Scope 1 emissions, Scope 2 using the market-based approach, and 
Scope 3 for raw materials, taking into account the boundaries and exclusion criteria given above, and for intermill 
transportation of intermediate products. 
Sold electricity-related emissions from internal power plants are not included in intensity calculations, and are 
reported separately. 
Emissions from oilfield services are reported but not included on the Tenaris intensity calculation. 
Scope 3 emissions 
Most of our seamless steel pipe products are manufactured in integrated steelmaking operations using the electric 
arc furnace route, where principal raw materials are steel scrap, DRI, HBI, pig iron, and ferroalloys. We 
complement our steel needs by purchasing steel bars from third parties. Our welded steel pipe products are 
processed from purchased steel coils.  
We report Scope 3 emissions related to the purchase of steelmaking raw materials and steel bars and coils 
purchased from external suppliers used at our tubular production and processing facilities. Based on the results of 
our life cycle analysis and our certified Environmental Product Declaration, we conclude that raw materials and 
steel bars and coils are the most relevant source of Scope 3 emissions. Our certified Environmental Product 
Declaration is available at: www.tenaris.com/en/sustainability/environment. Information contained in or otherwise 
accessible through our Internet website is not a part of this annual report. 
We use supplier-specific emission factors whenever possible. Tenaris reviews information about its suppliers where 
provided and applies internal criteria to define applicability. As confidence in data increases over time, when 
emission factors are found to be more accurate, they are applied from that moment on but not always applied to 
past years, as there is no certainty about their applicability with the same values. For those inputs where values are 
not expected to change over time, these may be applied to previous years. If supplier-based data is unavailable 
other sources are used e.g., worldsteel, IEA, etc. 
Since 2022, we have been reporting other Scope 3 categories such as upstream emissions from fuels used and 
emissions from the transport of intermediate and final products. In February 2025 among other changes 
described above, we have restated our Scope 3 emissions intensity by adding intermill transportation of unfinished 
products. 
Emissions calculated for the transport of intermediate and final products exclude the following: maritime 
movements, specifically spot exports in container/liner from the U.S. and Canada; inland transport within Brazil, 
Indonesia, China, Saudi Arabia and the UAE; and Rig Direct® movements in Argentina, Mexico and Colombia. 
These boundaries may differ from exclusions at the GHG sites included in the report as different criteria apply. The 
real distances of transport routes have been calculated for routes bearing over 3,000 tons in the reporting year for 
both inland and maritime transport; otherwise, a historic average is used. For air transportation, transport routes 
have been calculated for those bearing over 8 tons in the reporting year; otherwise, a historic average is used.  

Annual Report 2024 
196 
Emissions calculated for raw materials transport include the following considerations: included raw materials are 
scrap, iron pellets, lime and pig iron, whereas excluded raw materials are ferroalloys and metals, carbon and 
anthracite, which represent 4% of the total volume of raw materials used, excluding purchased steel. The 
transport of acquired steel and steel products is excluded from the calculation. The countries covered are those 
where Tenaris operates steel production sites. Scrap transport is based on mapping 90% of scrap purchases and 
distances to our facilities, while the remaining 10% is an estimate. Internal in-plant movements and return 
distances are excluded from the calculation. Emissions factors used for transportation emissions estimation are 
based on the GLEC Framework. 
Scope 3 emissions are subject to a high level of measurement uncertainty, due to data availability and quality, as 
well as measurement methods used across entities in the value chain. To measure Scope 3 emissions, we have 
taken into account the boundaries and exclusion criteria detailed above. 
Restatement of the baseline on the CO2-eq intensity and absolute emissions reported 
Acquisitions, mergers, and divestitures are tracked over time and will be included in the base year calculation if 
their influence on total emissions exceeds 10%, considering the production level of the sites when 
acquisition/merger or divestiture occurs.  
In 2024 we completed the acquisition of Mattr’s pipe coating business and we included our GPC (welded pipe 
mill in Saudi Arabia) and Isoplus (coating facility in Italy) operations on the inventory and intensity calculation. 
Since the accumulated acquisitions are influencing more than the defined threshold we are restating the baseline 
on 2024. 
To restate the baseline for each of the sites and businesses acquired since 2018, we considered the emissions on 
Scope 1, 2 and 3 accounted according to Tenaris methodology, from the first year they started to be accounted in 
Tenaris and replicated those emissions up to 2018. 
The following table shows the total emissions added per year, divided per scope and category, indicating if it is 
included on the Tenaris intensity calculation.

Sites included on the restatement process are: Saudi Steel Pipes (welded pipe mill in Saudi Arabia), Koppel (EAF 
steel mill in the U.S.), Ambridge (seamless pipe rolling mill in the U.S.), Coating operations including sites from 
Mattr’s pipe coating business (Indonesia, Norway, Mexico, Canada and the UAE) and Isoplus (Italy), and in GPC 
(welded mill in Saudi Arabia). 
Energy 
Renewable electricity accounts for the self-generation of renewable electricity, electricity obtained through 
renewable power purchase agreements (“PPA”) that may include renewable energy certificates (“RECs”) or 
Guarantees of Origin (“GOs”), local supplier programs, or other green power products that include certified 
renewable electricity. Energy consumption does not include oilfield services unless otherwise stated. 
Emissions from self-power generation sold to the grid are accounted for in Scope 1.

Air emissions 
• 
Particular Matter (“PM”) emissions on steel shops are measured on continuous monitoring system as well 
as flow on stacks and operating time. Equipment is calibrated routinely to ensure reliability 
• 
PM emissions on other processes than steel shops are calculated based on continuous monitoring or spot 
monitoring performed during the year, flow estimation and operating time. 
• 
NOX is calculated based on spot monitoring campaigns and calculated considering stack flow estimation 
and operating time for the process. 
• 
VOC is calculated for varnishing processes, based on the consumption of varnish and solvent and content 
of VOC according to the Safety Data Sheet (“SDS”) of the chemicals. 
• 
Data is collected locally and reported routinely to the corporate area for KPI calculation. 
 
Water  
Water data is compiled through a combination of direct measurements, sampling, and extrapolation. We ensure 
that the data is accurate and reflective of our actual water use. The share of the measure obtained from direct 
measurement, sampling, and best estimates is carefully balanced to provide a comprehensive overview of our 
water consumption. 
Water used is measured and/ or estimated by our sites, at pertinent points. Discharge water is measured or 
estimated and difference with water intake is used to calculate consumption. 
 
Water recycled is measured or estimated based on internal water systems like pumps and operating time of the 
system. 
 
Water withdrawal intensity: Tubular production and processing sites (including steel shops). 
 
Waste 
Waste data is collected locally weighted at the different sites or third parties. Waste is categorized according to its 
properties and characteristics. Destination depends on waste characteristics and local treatment or recycling 
infrastructure available. 
 
Recycling content in our steel: Proportion of recycled material in our steel calculated according to the ISO 14021 
standard. 
 
Material efficiency (sites with steel shops): The methodology is aligned with that of worldsteel. Sites covered are 
Dalmine, Koppel, Siderca, Silcotub and Tamsa. 
 
Residues and co-products reuse or recycling. All sites include waste, coproducts generated and reused or recycled. 
 
Human capital  
Gender pay gap 
 
The gender pay gap is the difference of average pay levels between female and male employees, expressed as the 
percentage of the average pay level of male employees. The gender pay gap in Tenaris is 95%. (Description: 
Weighted average resulting from evaluating the proportion by cluster and country, of the average salaries of 
women over men). 
 
Employee headcount 
 
Employee figures are based on the Tenaris Active Headcount Database, with no Full-Time Equivalent estimations. 
The data reflects the running rate as of the end of December for each year.

To the Management of Tenaris, S.A. 
 
Independent Practitioner’s Limited Assurance Report on Tenaris S.A.’s Selected Information 
 
Limited assurance conclusion 
 
We have conducted a limited assurance engagement on certain information disclosed in the 2024 
Sustainability Statement (the “Sustainability Report”) section of the Annual Report of Tenaris S.A. and 
its subsidiaries (together the “Group”) included in the Annex II of the Sustainability Report as at 
31 December 2024 and for the year then ended as set out in the table attached below in Exhibit 1 
(the “Selected Information”). 
 
Based on the procedures we have performed and the evidence we have obtained, nothing has come to 
our attention that causes us to believe that the Selected Information is not prepared, in all material 
respects, in accordance with the Assessment Criteria as set forth in the methodologies defined by the 
Group and applied as explained in Exhibit 1 and in the Sustainability Report under the section 
Sustainability Statement Accounting Policies (the “Assessment Criteria”).  
 
Basis for conclusion 
 
We conducted our limited assurance engagement in accordance with International Standard on 
Assurance Engagements (ISAE 3000 (Revised)), Assurance Engagements Other Than Audits or 
Reviews of Historical Financial Information (ISAE 3000 (Revised)), issued by the International Auditing 
and Assurance Standards Board (IAASB), as adopted for Luxembourg by the Institut des Réviseurs 
d’Entreprises (IRE). 
 
We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our 
conclusion. Our responsibilities under this standard are further described in the Responsibility of the 
“Réviseur d’entreprises agréé” section of our report.  
 
Our independence and quality management 
 
We have complied with the independence and other ethical requirements of the International Code of 
Ethics for Professional Accountants (including International Independence Standards) issued by the 
International Ethics Standards Board for Accountants as adopted for Luxembourg by the “Commission 
de Surveillance du Secteur Financier” (CSSF), which is founded on fundamental principles of integrity, 
objectivity, professional competence and due care, confidentiality and professional behavior.  
 
Our firm applies International Standard on Quality Management 1, as adopted for Luxembourg by the 
CSSF, which requires the firm to design, implement and operate a system of quality management 
including policies or procedures regarding compliance with ethical requirements, professional standards 
and applicable legal and regulatory requirements. 
 
 

 
 
Responsibilities of the Management 
 
The Management of the Group is responsible for: 
 
• developing appropriate Assessment Criteria against which to assess the Selected Information and 
applying these consistently; 
 
• ensuring that those Assessment Criteria are relevant and appropriate to the Group and the intended 
users of the Selected Information; 
 
• designing, implementing and maintaining internal control procedures that provide adequate control 
over Selected Information and the preparation and presentation of Selected Information in the 
Sustainability Report for the year ending 31 December 2024 that is free from material misstatement, 
whether due to fraud or error;  
 
• selecting and applying appropriate sustainability reporting methods, and making assumptions and 
estimates that are reasonable in the circumstances;  
 
• the preparation of the Selected Information in accordance with the Assessment Criteria; and  
 
• retention of sufficient, appropriate records to support the reported data and assertions included in 
the Selected Information. 
 
Inherent limitations 
 
Non-financial performance information is subject to more inherent limitations than financial information, 
given the characteristics of the subject matter and the methods used for determining such information. 
The absence of a significant body of established practice on which to draw allows for the selection of 
different but acceptable measurement techniques which can result in materially different measurements 
and can impact comparability. The precision of different measurement techniques may also vary. 
Qualitative interpretations of relevance, materiality, the accuracy of data and estimates of margins of 
uncertainty on data are subject to individual assumptions and judgements.  
 
Responsibility of the “Réviseur d’entreprises agréé” 
 
Our responsibility is to plan and perform the assurance engagement to obtain limited assurance about 
whether the Selected Information is free from material misstatement, whether due to fraud or error, and 
to issue a limited assurance report that includes our conclusion. Misstatements can arise from fraud or 
error and are considered material if, individually or in aggregate, they could reasonably be expected to 
influence decisions of users taken on the basis of the Selected Information.  
 
As part of a limited assurance engagement in accordance with ISAE 3000 (Revised) we exercise 
professional judgement and maintain professional scepticism throughout the engagement. We also:  
 
determine the suitability in the circumstances of the Group’s use of Assessment Criteria as the basis for 
the preparation of the Selected Information; 
 
 

 
 
perform risk assessment procedures, including obtaining an understanding of internal control relevant 
to the engagement, to identify where material misstatements are likely to arise, whether due to fraud or 
error, but not for the purpose of providing a conclusion on the effectiveness of the Group’s internal 
control;  
 
design and perform procedures responsive to where material misstatements are likely to arise in the 
Selected Information. The risk of not detecting a material misstatement resulting from fraud is higher 
than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, 
misrepresentations, or the override of internal control.  
 
Summary of the work performed 
 
A limited assurance engagement involves performing procedures to obtain evidence about the Selected 
Information. The procedures in a limited assurance engagement vary in nature and timing from, and are 
less in extent than for, a reasonable assurance engagement. Consequently, the level of assurance 
obtained in a limited assurance engagement is substantially lower than the assurance that would have 
been obtained had a reasonable assurance engagement been performed.  
 
The nature, timing and extent of procedures selected depend on professional judgement, including the 
identification of where material misstatements are likely to arise in the Selected Information, whether 
due to fraud or error. 
 
In conducting our limited assurance engagement, we: 
 
• obtained an understanding of the Selected Information and related disclosures, including Group’s 
reporting processes relevant to the preparation of the Selected Information; 
 
• obtained an understanding of the Assessment Criteria and their suitability for the evaluation and/or 
measurements of the Selected Information; 
 
• evaluated whether all information identified by the process to identify the information reported in the 
Selected Information is included in the Selected Information;  
 
• based on that understanding, assessed the risks that the Selected Information may be materially 
misstated and determination of the nature, timing and extent of further procedures; 
 
• performed inquiries of relevant Group personnel and third parties on Selected Information; 
 
• performed analytical procedures related to the Selected Information; 
 
• evaluated the methods, assumptions and data for developing the estimates made by management 
in the preparation of the Selected Information; 
 
• performed substantive assurance procedures on a selective basis of evidence supporting the 
reported Selected Information and assessed the related disclosures; and 
 
• reviewed the presentation of the selected information and related disclosures included in the 
Sustainability Report. 
 

 
 
Other Matter 
 
The comparative sustainability information of the Group as at 31 December 2023 and for the year then 
ended was not subject to an assurance engagement. Our conclusion is not modified in respect of this 
matter. 
 
Restriction on distribution and use 
 
This report, including the opinion, has been prepared for and only for the Management of the Group in 
accordance with the terms of our engagement letter and is not suitable for any other purpose. We do 
not accept any responsibility to any other party to whom it may be distributed.

LEGAL AND FINANCIAL INFORMATION 
Financial Information 
Consolidated Statements and Other Financial Information 
See “Financial Statements”. 
Legal Proceedings 
 
Tenaris is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, 
employee, tax and environmental-related 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, the Company is unable to make a reliable estimate of the expected financial effect that will result 
from ultimate resolution of the proceeding. In those situations, the Company 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, 
the Company was able to make a reliable estimate of the expected loss or range of probable loss and, depending 
on the likelihood of occurrence, in some of such cases has accrued a provision for such loss but believes that 
publication of this information on a case-by-case basis would seriously prejudice the 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 its consolidated financial 
statements (see notes 24 “Non-current allowances and provisions” and 25 “Current allowances and provisions” 
to our audited consolidated financial statements included in this annual report) are adequate based upon 
currently available information. However, if management’s estimates prove incorrect, current reserves could be 
inadequate and the Company could incur a charge to earnings which could have a material adverse effect on its 
results of operations, financial condition, net worth and cash flows. 
Material Legal Proceedings 
 
A summary description of Tenaris’s material outstanding legal proceedings as of December 31, 2024, is included 
in note 27 “Contingencies, commitments and restrictions to the distribution of profits” to our audited 
consolidated financial statements included in this annual report, which summary description is incorporated herein 
by reference. In addition, Tenaris is subject to other legal proceedings, none of which is believed to be material.  
 
Dividend Policy 
The Company does not have, and has no current plans to establish, a formal dividend policy governing the 
amount and payment of dividends or other distributions. For a description of the shareholders’ and holders of 
ADS’ rights to receive dividends and the conditions to declare and pay dividends, please refer to “Information on 
the Company - Corporate Governance Statement - Corporate Governance”.

record date of May 20, 2025 and an ex-dividend date of May 19, 2025 for securities listed in Europe and Mexico, 
and an ex-dividend date of May 20, 2025 for securities listed in the United States. Treasury shares are not entitled 
to dividend distributions.

Additional Information 
Exchange Controls 
Many of the countries that are important markets for us or in which we have substantial assets have histories of 
substantial government intervention in currency markets, volatile exchange rates and government-imposed 
currency controls. These include mainly Argentina, Brazil, Indonesia, Mexico, Nigeria and Romania.  
The exchange rate of the ARS against the U.S. dollar was subject to a “crawling-peg” devaluation of 
approximately 2% per month against the U.S. dollar during 2024. 
Between September 2019 and December 2023, the Argentine government imposed significant restrictions on 
foreign exchange transactions; however, the new administration in Argentina eased certain restrictions and other 
changes to such regulations are expected. At the date of this annual report, the application of existing foreign 
exchange regulations remains uncertain, and the scope and timing of upcoming changes remain 
unknown. Currently, Argentine companies are required to repatriate export proceeds from sales of goods and 
services (including U.S. dollars obtained through advance payment and pre-financing facilities) and convert such 
proceeds into ARS at the official exchange rate. Since December 13, 2023, up to 20% of export proceeds can be 
sold for Argentine pesos through securities transactions resulting in a higher implicit exchange rate as explained 
below. This percentage has changed and is expected to change over time. Sovereign bonds were issued to pay 
imports of goods cleared and services rendered on or prior to December 12, 2023, but such bonds cover only a 
portion total import debts. Import payments for services rendered and goods cleared after December 12, 2023, 
do not require government approval but cannot be paid in advance or at sight and are subject to a 30-day 
deferred payment schedule. In addition, during 2024 import payments were subject to import taxes that 
significantly increased prices of imported goods and services; import taxes, though, were eliminated during 
December 2024. Argentine companies must still obtain prior Argentine Central Bank authorization, which is rarely 
(if ever) granted, to access the foreign exchange market to make dividend payments.  
The existing measures substantially limit the ability of Argentine companies to obtain foreign currency and make 
certain payments and distributions out of Argentina at the official exchange rate. Access to foreign currency and 
transfers out of Argentina can be achieved, however, through securities transactions involving bonds or shares 
with multiple listings, resulting in a different implicit exchange rate, generally higher than the official exchange 
rate. Such transactions are subject to certain restrictions and limits, which change from time to time, and often 
result in a financial loss being generated at the time of making any such transaction. 
As of December 31, 2024, the total equity of Argentine subsidiaries represented approximately 11% of Tenaris’s 
total equity. 
 
For additional information regarding factors affecting the Argentine economy, see “Risk Factors - Risks Relating to 
our Business and Industry - Adverse economic or political conditions in the countries where we operate or sell our 
products and services may decrease our sales or disrupt our manufacturing operations, thereby adversely affecting 
our revenues, profitability and financial condition”. For additional information on current foreign exchange 
restrictions in Argentina, see note 29 “Foreign exchange control measures in Argentina” of our audited 
consolidated financial statements included in this annual report.

Taxation 
The following discussion of the material Luxembourg and U.S. federal income tax consequences of an investment 
in our shares and ADSs is based upon laws and relevant interpretations thereof in effect as of the date of this 
annual report, all of which are subject to change. This discussion does not address all possible tax consequences 
relating to an investment in our shares or ADSs, including the tax consequences under U.S. state and local tax 
laws.  
Grand Duchy of Luxembourg 
This section describes the material Luxembourg tax consequences of owning or disposing of shares or ADSs.  
It is not intended to be, nor should it be construed to be, legal or tax advice. You should, therefore, consult your 
own tax advisor regarding local or foreign tax consequences, including Luxembourg tax consequences of owning 
and disposing of shares or ADSs in your particular circumstances.  
As used herein, a “Luxembourg individual” means an individual resident in Luxembourg who is subject to 
personal income tax (impôt sur le revenu) on his or her worldwide income from Luxembourg or foreign sources, 
and a “Luxembourg corporate holder” means a company (that is, a fully taxable collectivité within the meaning of 
Article 159 of the Luxembourg Income Tax Law) resident in Luxembourg subject to Luxembourg corporate income 
tax (impôt sur le revenu des collectivités) and Luxembourg municipal business tax (impôt commercial communal) 
on its worldwide income from Luxembourg or foreign sources. For the purposes of this summary, Luxembourg 
individuals and Luxembourg corporate holders are collectively referred to as “Luxembourg Holders”. A “non-
Luxembourg Holder” means any investor in shares or ADSs of the Company other than a Luxembourg Holder.  
Corporate Reorganization 
The Company was established as a Luxembourg société anonyme holding under Luxembourg’s 1929 holding 
company regime. Until termination of such regime on December 31, 2010, holding companies incorporated 
under the 1929 regime (including the Company) were exempt from Luxembourg corporate income tax, 
Luxembourg municipal business tax, Luxembourg net wealth tax and Luxembourg withholding tax over dividends 
distributed to shareholders. 
On January 1, 2011, the Company became an ordinary public limited liability company (société anonyme) and, 
effective as from that date, the Company is subject to all applicable Luxembourg taxes, (including, among others, 
Luxembourg corporate income tax on its worldwide income). 
In light of the impending termination of Luxembourg’s 1929 holding company regime, in the fourth quarter of 
2010, the Company carried out a multi-step corporate reorganization, which included, among other transactions, 
the contribution of most of the Company’s assets and liabilities to a wholly-owned, newly-incorporated 
Luxembourg subsidiary and the restructuring of indirect holdings in certain subsidiaries. The first phase of the 
corporate reorganization was completed in December 2010 and resulted in a non-taxable revaluation of the 
accounting value (under Luxembourg GAAP) of the Company’s assets. The second phase of the reorganization 
was completed in 2011. 
Following the completion of the first phase of the corporate reorganization, and upon its conversion into an 
ordinary Luxembourg holding company, the Company recorded a special reserve in its tax balance sheet. Dividend 
distributions for the foreseeable future will be charged to the special reserve and therefore should not be subject 
to Luxembourg withholding tax.

Tax regime applicable to realized capital gains  
Luxembourg Holders  
Luxembourg resident individual holders  
Capital gains realized by Luxembourg resident individuals who do not hold their shares or ADSs as part of a trade 
or business (i.e. capital gains on private assets) and who hold (together, directly or indirectly, with his or her 
spouse or civil partner and underage children) no more than 10% of the share capital of the Company, at any 
time during the five-year period preceding the disposition will only be taxable (at a progressive rate) if they are 
realized on a sale of shares or ADSs that takes place before their acquisition or within the first six months 
following their acquisition (i.e. speculative gain). After the six-month period, capital gains are not taxed unless the 
resident individual holds (together, directly or indirectly, with his or her spouse or civil partner and underage 
children) more than 10% of the share capital of the Company at any time during the five-year period preceding 
the disposition. 
If such shares or ADSs are held as part of a commercial or industrial business, capital gains would be taxable in the 
same manner as income from such business.  
Capital gains realized by Luxembourg resident individuals holding (alone or together with the resident’s spouse or 
civil partner and underage children) directly or indirectly more than 10% of the capital of the Company at any 
time during the five years prior to the sale, (or if the Luxembourg resident individuals have received the shares for 
no consideration within the last five years and the former holder held at least 10% in the capital of the company 
at any moment during said five years) will be taxable at half of the individual’s applicable global tax rate (as 
determined progressively), if a holding period of six months following their acquisition elapsed (21% for 2024). 
Within the six-month period, progressive income tax rates apply (ranging from 0 to 42%10 in 2024). 
Luxembourg resident corporate holders  
Capital gains, including currency exchange gains, realized upon the disposal of shares or ADSs by a fully taxable 
resident corporate holder will in principle be subject to Luxembourg corporate income tax and Luxembourg 
municipal business tax. The combined applicable rate (including an unemployment fund contribution) for a 
corporate holder established in Luxembourg-City is 24.94% for the fiscal year ending 2024. An exemption from 
such taxes may be available to the Luxembourg resident corporate holder pursuant to Article 1 of the Grand Ducal 
Decree dated December 21, 2001, as amended, in combination with article 166 of the Luxembourg Income Tax 
Law subject to the fulfillment of the conditions set forth therein.  
Non-Luxembourg Holders  
Non-Luxembourg individual holders 
An individual who is a non-Luxembourg holder of shares or ADSs (and who does not have a permanent 
establishment, a permanent representative or a fixed place of business in Luxembourg) will only be subject to 
Luxembourg taxation on capital gains arising upon disposal of such shares or ADSs if such holder has (alone or 
together with his or her spouse, civil partner and underage children) directly or indirectly held more than 10% of 
the capital of the Company at any time during the past five years preceding the disposal, and either (i) such non-
Luxembourg holder has been a resident of Luxembourg for tax purposes for at least 15 years and has become a 
non-resident within the last five years preceding the realization of the gain, subject to any applicable tax treaty, or 
(ii) the disposal of shares or ADSs occurs within six months from their acquisition (or prior to their actual 
acquisition), subject, however, to any applicable tax treaty.  
 
 
10 A 7% surcharge for the Employment Fund applies on the income tax due. The surcharge for the Employment Fund amounts to 9% for 
taxpayer in tax class 1 or 1a with taxable income exceeding EUR 150,000 (EUR 300,000 for taxpayer in tax class 2). 

Annual Report 2024 
234 
 
Non-Luxembourg corporate holders 
A corporate non-Luxembourg holder (that is, a collectivité within the meaning of Article 159 of the Luxembourg 
Income Tax Law), which has a permanent establishment, a permanent representative or a fixed place of business 
in Luxembourg to which shares or ADSs are attributable, will bear Luxembourg corporate income tax and 
Luxembourg municipal business tax on a gain realized on a disposal of such shares or ADSs as set forth above for 
a Luxembourg corporate holder. However, capital gains, including currency exchange gains, realized on the sale 
of the shares or ADSs may benefit from the full exemption provided for by Article 1 of the Grand Ducal Decree 
dated December 21, 2001, as amended, in combination with Article 166 of the Luxembourg Income Tax Law 
subject in each case to fulfillment of the conditions set out therein.  
A corporate non-Luxembourg holder, which has no permanent establishment, permanent representative or fixed 
place of business in Luxembourg to which the shares or ADSs are attributable, will bear non-resident capital gains 
tax on a gain realized on a disposal of such shares or ADSs under the same conditions applicable to an individual 
non-Luxembourg holder, as set out above.  
Tax regime applicable to distributions  
Withholding tax  
Distributions to holders are in principle subject to a 15% Luxembourg withholding tax computed on the gross 
amount distributed. The rate of the withholding tax may be reduced pursuant to double tax treaties existing 
between Luxembourg and the country of residence of the relevant holder, subject to the fulfillment of the 
conditions set forth therein. However, distributions imputed for tax purposes to the special reserve (please see 
above paragraph “corporate reorganization”) should be exempt from Luxembourg withholding tax under the 
current tax law. 
Nevertheless, a withholding tax exemption may apply if the distribution is made to (as far as relevant in the case at 
hand):  
• 
a Luxembourg resident corporate holder (that is, a fully taxable collectivité within the meaning of article 
159 of the Luxembourg Income Tax Law); 
• 
an undertaking of collective character which is resident of a Member State of the EU and is referred to by 
article 2 of the EU Council Directive of November 30, 2011, concerning the common fiscal regime 
applicable to parent and subsidiary companies of different member states (2011/96/UE) as amended, 
(subject to the general anti-abuse rule provided for by Council Directive 2015/121/EU as implemented into 
Luxembourg law); 
• 
a capital company or a cooperative company resident in Norway, Iceland or Liechtenstein and subject to a 
tax comparable to corporate income tax as provided by the Luxembourg Income Tax Law; 
• 
a capital company resident in Switzerland which is subject to corporate income tax in Switzerland without 
benefiting from an exemption; 
• 
an undertaking with a collective character subject to a tax comparable to corporate income tax as provided 
by the Luxembourg Income Tax Law which is resident in a country that has concluded a double tax treaty 
with Luxembourg; and  
• 
a Luxembourg permanent establishment of one of the above-mentioned categories, provided each time 
that at the date of payment, the holder holds or commits to hold directly (or through a company regarded 
as tax transparent from a Luxembourg tax perspective), during an uninterrupted period of at least twelve 
months, shares or ADSs representing at least 10% of the share capital of the Company or acquired for an 
acquisition price of at least EUR 1,200,000.  
 
 

Annual Report 2024 
235 
 
Luxembourg Holders  
With the exception of Luxembourg corporate holders benefiting from the exemption referred to above, 
Luxembourg individual holders, and Luxembourg corporate holders fully subject to Luxembourg corporate tax, 
must include the distributions paid on the shares or ADSs in their taxable income, 50% of the amount of such 
dividends being exempt from tax. The applicable withholding tax can, under certain conditions, entitle the 
relevant Luxembourg Holder to a tax credit.  
Non-Luxembourg Holders  
Non-Luxembourg Holders of shares or ADSs and who do not have a permanent establishment, a permanent 
representative or a fixed place of business in Luxembourg to which the shares or ADSs would be attributable are 
not liable for any Luxembourg tax on dividends paid on the shares or ADSs, other than a potential withholding tax 
as described above. 
 
Net wealth tax  
Luxembourg Holders  
Luxembourg net wealth tax will not be levied on a Luxembourg holder with respect to the shares or ADSs held 
unless (i) the Luxembourg holder is a legal entity subject to net wealth tax in Luxembourg; or (ii) the shares or 
ADSs are attributable to an enterprise or part thereof which is carried on through a permanent establishment, a 
fixed place of business or a permanent representative in Luxembourg. 
Net wealth tax is levied annually at the rate of 0.5% for taxable net wealth not exceeding EUR 500,000,000 and 
at a rate of 0.05% for the net wealth exceeding EUR 500,000,000, of enterprises resident in Luxembourg, as 
determined for net wealth tax purposes. The shares or ADSs may be exempt from net wealth tax subject to the 
conditions set forth by Paragraph 60 of the Luxembourg Law of October 16, 1934, on the valuation of assets 
(Bewertungsgesetz), as amended. 
A minimum net wealth tax charge applies as of January 1, 2016, for all corporate entities having their statutory 
seat or central administration in Luxembourg. Subject to certain conditions, the amount of minimum net wealth 
tax may vary. 
Non-Luxembourg Holders  
Luxembourg net wealth tax will not be levied on a non-Luxembourg holder with respect to the shares or ADSs 
held unless the shares or ADSs are attributable to an enterprise or part thereof which is carried on through a 
permanent establishment or a permanent representative in Luxembourg. The shares or ADSs may be exempt from 
net wealth tax subject to the conditions set forth by Paragraph 60 of the Luxembourg Law of October 16, 1934 
on the valuation of assets (Bewertungsgesetz), as amended. 
Stamp and registration taxes  
No registration tax or stamp duty will be payable by a holder of shares or ADSs in Luxembourg solely upon the 
disposal of shares or ADSs by sale or exchange. 
Estate and gift taxes  
No estate or inheritance tax is levied on the transfer of shares or ADSs upon the death of a holder of shares or 
ADSs in cases where the deceased was not a resident of Luxembourg for inheritance tax purposes and no gift tax 
is levied upon a gift of shares or ADSs if the gift is not passed before a Luxembourg notary or recorded in a deed 
registered in Luxembourg.  
Where a holder of shares or ADSs is a resident of Luxembourg for tax purposes at the time of the holder’s death, 
the shares or ADSs are included in its taxable estate for inheritance tax or estate tax purposes.

U.S. federal income taxation  
This section describes the material U.S. federal income tax consequences to a U.S. holder (as defined below) of 
owning shares or ADSs. It applies to you only if you hold your shares or ADSs as capital assets for U.S. federal 
income tax purposes. This discussion addresses only U.S. federal income taxation and does not discuss all of the 
tax consequences that may be relevant to you in light of your individual circumstances, including foreign, state or 
local tax consequences, estate and gift tax consequences, and tax consequences arising under the Medicare 
contribution tax on net investment income or the alternative minimum tax. This section does not apply to you if 
you are a member of a special class of holders subject to special rules, including:  
• 
a dealer in securities;  
• 
a bank;  
• 
a trader in securities that elects to use a mark-to-market method of accounting for securities holdings;  
• 
a tax-exempt organization;  
• 
a person who invests through a pass-through entity, including a partnership;  
• 
a life insurance company;  
• 
a person that actually or constructively owns 10% or more of the combined voting power of our voting 
stock or of the total value of our stock (including ADSs);  
• 
a person that holds shares or ADSs as part of a straddle or a hedging or conversion transaction for U.S. 
federal income tax purposes;  
• 
a person that purchases or sells shares or ADSs as part of a wash sale for U.S. federal income tax purposes; 
or  
• 
a person whose functional currency is not the U.S. dollar. 
This section is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and 
proposed regulations, published rulings and court decisions, all as currently in effect, as well as on the Convention 
between the Government of the Grand Duchy of Luxembourg and the Government of the United States of 
America for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on 
Income and Capital (the “Treaty”). These laws are subject to change, possibly on a retroactive basis. In addition, 
this section is based in part upon the assumption that each obligation in the ADS deposit agreement and any 
related agreement will be performed in accordance with its terms.  
If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds the shares 
or ADSs, the U.S. federal income tax treatment of a partner will generally depend upon the status of the partner 
and the activities of the partnership. Each such partner of a partnership that holds the shares or ADSs is urged to 
consult his, her or its own tax advisor.  
You are a U.S. holder if you are a beneficial owner of shares or ADSs and you are, for U.S. federal income tax 
purposes:  
• 
an individual citizen or resident of the United States;  
• 
a domestic corporation (or an entity treated as a domestic corporation);  
• 
an estate whose income is subject to U.S. federal income tax regardless of its source; or  
• 
a trust if (i) a U.S. court can exercise primary supervision over the trust’s administration and one or more 
U.S. persons are authorized to control all substantial decisions of the trust or (ii) the trust has a valid 
election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.  

Annual Report 2024

In general, and taking into account the earlier assumptions, for U.S. federal income tax purposes, if you hold 
ADSs, you will be treated as the owner of the shares represented by those ADSs. Exchanges of shares for ADSs, 
and ADSs for shares, generally will not be subject to U.S. federal income tax.  
The tax treatment of your shares or ADSs will depend in part on whether or not we are classified as a passive 
foreign investment company (“PFIC”), for United States federal income tax purposes. Except as discussed below 
under “PFIC Rules”, this discussion assumes that we are not classified as a PFIC for United States federal income 
tax purposes. 
You should consult your own tax advisor regarding the U.S. federal, state and local and other tax consequences 
of owning and disposing of shares or ADSs in your particular circumstances.  
Taxation of distributions 
Under the U.S. federal income tax laws, if you are a U.S. holder, the gross amount of any distribution we pay out 
of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes), other 
than certain pro-rata distributions of our shares, will be treated as a dividend that is subject to U.S. federal income 
taxation. If you are a non-corporate U.S. holder, dividends paid to you that constitute qualified dividend income 
will be taxable to you at the preferential rates applicable to long-term capital gains provided that you hold shares 
or ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date and 
meet other holding period requirements. Dividends we pay with respect to the shares or ADSs generally will be 
qualified dividend income, provided that, in the year that you receive the dividend, we are eligible for the benefits 
of the Treaty. We believe that we are currently eligible for the benefits of the Treaty and therefore expect that 
dividends on the shares or ADSs will be qualified dividend income, but there can be no assurance that we will 
continue to be eligible for the benefits of the Treaty. 
 
You must generally include any Luxembourg tax withheld from the dividend payment in this gross amount even 
though you do not in fact receive it. The dividend is taxable to you when you receive it, or, in the case of ADSs, 
when the Depositary receives the dividend, actually or constructively. The dividend will not be eligible for the 
dividends-received deduction generally allowed to U.S. corporations in respect of dividends received from other 
U.S. corporations. Distributions in excess of current and accumulated earnings and profits, as determined for U.S. 
federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your basis in the 
shares or ADSs and thereafter as capital gain. However, we do not expect to calculate earnings and profits in 
accordance with U.S. federal income tax principles. Therefore, you should expect that a distribution will generally 
be treated as a dividend (as discussed above).  
Dividends will generally be income from sources outside the United States and, generally, will be “passive” 
income for purposes of computing the foreign tax credit allowable to you.  
Subject to certain limitations, the Luxembourg tax withheld in accordance with the Treaty and paid over to 
Luxembourg may be creditable or deductible against your U.S. federal income tax liability. However, under 
recently finalized U.S. Treasury regulations, it is possible that taxes may not be creditable unless you are eligible 
for and elect to apply the benefits of the Treaty. Special rules apply in determining the foreign tax credit limitation 
with respect to dividends that are subject to the preferential tax rates. To the extent a refund of the tax withheld 
is available to you under Luxembourg law or under the Treaty, the amount of tax withheld that is refundable will 
not be eligible for credit against your U.S. federal income tax liability. 
In certain circumstances, if you have held ADSs for less than a specified minimum period during which you are not 
protected from risk of loss, or are obligated to make payments related to the dividends, you will not be allowed a 
foreign tax credit for foreign taxes imposed on dividends that we pay. 
The rules governing the foreign tax credit are complex. You are urged to consult your tax advisors regarding the 
availability of the foreign tax credit under your particular circumstances.  
 

Annual Report 2024

Taxation of capital gains  
If you are a U.S. holder and you sell or otherwise dispose of your shares or ADSs, you will recognize capital gain or 
loss for U.S. federal income tax purposes equal to the difference between the U.S. dollar value of the amount that 
you realize and your tax basis, determined in U.S. dollars, in your shares or ADSs. Capital gain of a non-corporate 
U.S. holder is generally taxed at preferential rates where the property is held for more than one year. The gain or 
loss will generally be income or loss from sources within the United States for foreign tax credit limitation 
purposes. The deductibility of capital losses is subject to limitations.  
PFIC rules. Based on the Company’s current and expected income and assets, we believe that the shares or ADSs 
should not currently be treated as stock of a PFIC for U.S. federal income tax purposes, and we do not expect to 
become a PFIC in the foreseeable future. However, this conclusion is a factual determination that is made annually 
and thus may be subject to change. It is therefore possible that we could become a PFIC in a future taxable year. 
If we were to be treated as a PFIC, gain realized on the sale or other disposition of your shares or ADSs would in 
general not be treated as capital gain. Furthermore, if you are a U.S. holder, unless you are permitted to elect and 
you do elect to be taxed annually on a mark-to-market basis with respect to the shares or ADSs, upon sale or 
disposition of your shares or ADSs, you would generally be treated as if you had realized such gain and certain 
“excess distributions” ratably over your holding period for the shares or ADSs and would be taxed at the highest 
tax rate in effect for each such year to which the gain was allocated, together with an interest charge in respect 
of the tax attributable to each such year. With certain exceptions, your shares or ADSs will be treated as stock in a 
PFIC if we were a PFIC at any time during your holding period in your shares or ADSs. Dividends that you receive 
from us will not be eligible for the special tax rates applicable to qualified dividend income if we are a PFIC (or are 
treated as a PFIC with respect to you) either in the taxable year of the distribution or the preceding taxable year, 
but instead will be taxable at rates applicable to ordinary income and subject to the excess distribution regime 
described above.

Quantitative and Qualitative Disclosure about Market Risk 
The multinational nature of our operations and customer base expose us to a variety of risks, including the effects 
of changes in foreign currency exchange rates, interest rates and commodity prices. In order to reduce the impact 
related to these exposures, management evaluates exposures on a consolidated basis to take advantage of natural 
exposure netting. For the residual exposures, we may enter into various derivative transactions in order to reduce 
potential adverse effects on our financial performance. Such derivative transactions are executed in accordance 
with internal policies and hedging practices. We do not enter into derivative financial instruments for trading or 
other speculative purposes, other than non-material investments in structured products. 
The following information should be read together with section III, “Financial risk management” to our audited 
consolidated financial statements included elsewhere in this annual report.

Our weighted average interest rates before tax (considering hedge accounting), amounted to 6.52% at December 
31, 2024 and to 10.56% at December 31, 2023. 
Our financial liabilities (other than trade payables and derivative financial instruments) consist mainly of bank 
loans. As of December 31, 2023, U.S. dollar denominated financial debt plus debt denominated in other 
currencies swapped to the U.S. dollar represented 62% of total financial debt. 
Borrowings are classified under other financial liabilities and measured at their amortized cost. Tenaris estimates 
that the fair value (level 2) of its main borrowings is approximately 98.3% and 99.8% of its carrying amount 
(including interests accrued) in 2024 and 2023 respectively. Fair values were calculated using standard valuation 
techniques for floating rate instruments and comparable market rates for discounting cash flows. 
For further information about our financial debt, please see note 21 “Borrowings” to our audited consolidated 
financial statements included in this annual report. 
 
 

Annual Report 2024

Interest Rate Risk 
Fluctuations in market interest rates create a degree of risk by affecting the amount of our interest payments. At 
December 31, 2024, we had variable interest rate debt of $265 million and fixed rate debt of $172 million (of the 
fixed rate debt, $162 million is short-term). 
Foreign Exchange Rate Risk 
We manufacture and sell our products in a number of countries throughout the world and consequently we are 
exposed to foreign exchange rate risk. Since the Company’s functional currency is the U.S. dollar, the purpose of 
our foreign currency hedging program is mainly to reduce the risk caused by changes in the exchange rates of 
other currencies against the U.S. dollar. 
Most of our revenues are determined or influenced by the U.S. dollar. In addition, a relevant part of our costs 
corresponds to steelmaking raw materials and steel coils and plates, also determined or influenced by the U.S. 
dollar. However, outside the United States, a portion of our expenses is incurred in foreign currencies (e.g. labor 
costs). Therefore, when the U.S. dollar weakens in relation to the foreign currencies of the countries where we 
manufacture our products, the U.S. dollar-reported expenses increase. Had the U.S. dollar average exchange rate 
been weaker by 5% against the currencies of the countries where we have labor costs, operating income would 
have decreased approximately by $73 million in 2024, compared to $71 million in 2023. 
Our consolidated exposure to currency fluctuations is reviewed on a periodic basis. A number of hedging 
transactions are performed in order to achieve an efficient coverage in the absence of operative or natural 
hedges. Almost all of these transactions are forward exchange rate contracts. 
Because certain subsidiaries have functional currencies other than the U.S. dollar, the results of hedging activities 
as reported in the income statement under IFRS may not reflect entirely management’s assessment of its foreign 
exchange risk hedging needs. Also, intercompany balances between our subsidiaries may generate exchange rate 
results to the extent that their functional currencies differ. 
The value of our financial assets and liabilities is subject to changes arising out of the variation of foreign currency 
exchange rates. The following table provides a breakdown of our main financial assets and liabilities (including 
foreign exchange derivative contracts) that impact our profit and loss as of December 31, 2024.

The main relevant exposures as of December 31, 2024, were to Euro-denominated intercompany liabilities at 
certain subsidiaries whose functional currency is the U.S. dollar, Saudi Arabian Riyal-denominated financial and 
trade payables, ARS-denominated financial, trade, social and fiscal payables at our Argentine subsidiaries, for 
which the functional currency is the U.S. dollar, and Brazilian Real-denominated liabilities at certain Brazilian 
subsidiaries whose functional currency is the U.S. dollar. The Saudi Arabian Riyal is tied to the U.S. dollar. 
 
Foreign Currency Derivative Contracts 
The net fair value of our foreign currency derivative contracts amounted to a liability of $8 thousand at December 
31, 2024 and a liability of $2 million at December 31, 2023. For further detail on our foreign currency derivative 
contracts, please see note 26 “Derivative financial instruments - Foreign exchange and commodities derivative 
contracts and hedge accounting” to our audited consolidated financial statements included in this annual report. 
Concentration of Credit Risk 
No single customer comprised more than 10% of our net sales in 2024, 2023 and 2022. 
 
Tenaris maintains a strong, longstanding relationship with Pemex, one of the world’s largest crude oil and 
condensates producers and one of its largest customers. Over the past several months, Pemex has delayed 

Annual Report 2024 
242 
 
payments beyond the agreed-upon due dates, resulting in Tenaris having a significant credit exposure to Pemex, 
which represented approximately 17% of the Company’s overall credit exposure as of December 31, 2024, and 
approximately 20% of the Company’s overall credit exposure as of December 31, 2023. In December 2024, 
Pemex issued senior guaranteed floating rate notes due in 2025 that a financial institution purchased on the issue 
date, with Pemex agreeing to use a portion of the proceeds from the sale of such notes to pay off outstanding 
debt with one of the Company’s Mexican subsidiaries for approximately $200 million. 
 
Our credit policies related to sales of products and services are designed to identify customers with acceptable 
credit history, and to allow us to use credit insurance, letters of credit and other instruments designed to minimize 
credit risk whenever deemed necessary. We maintain allowances for impairment for potential credit losses. 
 
Commodity Price Risk 
 
In the ordinary course of its operations, Tenaris purchases commodities and raw materials that are subject to price 
volatility caused by supply conditions, political and economic variables and other factors. As a consequence, 
Tenaris is exposed to risk resulting from fluctuations in the prices of these commodities and raw materials. Tenaris 
fixes the prices of such raw materials and commodities for short-term periods, typically not in excess of one year, 
and in general hedging for these risks is performed on a limited basis. 
 
Commodities Derivative Contracts 
The net fair value of our commodities derivative contracts amounted to a liability of $0.8 million at December 31, 
2024 and an asset of $0.2 million at December 31, 2023. For further detail on our commodities derivative 
contracts, please see note 26 “Derivative financial instruments - Foreign exchange and commodities derivative 
contracts and hedge accounting” to our audited consolidated financial statements included in this annual report. 
Accounting for Derivative Financial Instruments and Hedging Activities 
We use derivative financial instruments principally to manage our exposure to fluctuations in exchange rates and 
prices of raw materials. Derivative financial instruments are classified as current or non-current assets or liabilities 
based on their maturity dates. Derivative financial instruments are initially recognized in the statement of financial 
position at fair value. We use market prices or specific tools for calculation of each instrument’s fair value, with 
such tools tested for consistency on a monthly basis. Market rates are used for all pricing operations. These 
include exchange rates, deposit rates and other discount rates matching the nature of each underlying risk. Gains 
or losses arising from changes in fair value of derivatives are recognized in Financial Results in the Consolidated 
Income Statement, except for derivatives that are designated and qualify for hedge accounting.   
We designate certain derivatives as hedges of particular risks associated with recognized assets or liabilities or 
highly probable forecast transactions. These transactions are classified as cash flow hedges. The effective portion 
of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in equity. 
Amounts accumulated in equity are then recognized in the income statement in the same period as the offsetting 
losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately 
in the income statement. The fair value of Tenaris’s derivative financial instruments (assets or liabilities) continues 
to be reflected in the statement of financial position. 
For transactions designated and qualifying for hedge accounting, we document at the inception of the transaction 
the relationship between hedging instruments and hedged items, as well as our risk management objectives and 
strategy for undertaking various hedge transactions. We also document our assessment on an ongoing basis, of 
whether the hedging instruments are effective in offsetting changes in the fair value or cash flow of hedged 
items. At December 31, 2024 and 2023, the effective portion of designated cash flow hedges which is included in 
Other Reserves in equity amounted to $0.6 million debit and $8.1 million credit respectively.

Description of Securities Other Than Equity Securities 
American Depositary Shares 
According to the Company’s deposit agreement, holders of ADSs may have to pay to the Depositary, either 
directly or indirectly, fees or charges up to the amounts set forth below: 
• 
a fee of $5.00 (or less) per 100 ADSs (or portion of 100 ADSs) for: issuance of ADSs, including issuances 
resulting from a distribution of shares or rights or other property; and cancellation of ADSs for the purpose 
of withdrawal, including if the deposit agreement terminates; 
• 
a fee of $0.02 (or less) per ADSs for any cash distribution to ADS registered holders, excluding cash 
dividend; 
• 
any charges for taxes and other governmental charges that the Depositary or the custodian may be 
required to pay on any ADS or share underlying an ADS (e.g., share transfer taxes, stamp duty or 
withholding taxes); and any charges incurred by the Depositary or its agents for servicing the depositary 
securities; 
• 
registration or transfer fees for transfer and registration of shares on our share register to or from the name 
of the Depositary or its agent when you deposit or withdraw shares; 
• 
expenses of the Depositary for cable, telex and facsimile transmissions (when expressly provided in the 
deposit agreement) and conversion of foreign currency; 
• 
a fee equivalent to the fee that would be payable if securities distributed to ADS holders had been shares 
and the shares had been deposited for issuance of ADSs for distribution of securities distributed to holders 
of deposited securities which are distributed by the Depositary to ADS registered holders; and 
• 
as necessary, charges for any costs incurred by the Depositary or its agents for servicing the deposited 
securities. 
The Depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or 
surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects 
fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a 
portion of distributable property to pay the fees. The Depositary may collect its annual fee for depositary services 
by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts 
of participants acting for them. The Depositary may generally refuse to provide fee-attracting services until its fees 
for those services are paid. 
Under the deposit agreement with the Depositary, the Depositary is not liable to holders of ADSs, except that the 
Depositary agrees to perform its obligations specifically set forth therein without gross negligence and willful 
misconduct. 
Fees Payable by the Depositary to the Company 
Under its agreement with the Depositary, the Company is entitled to receive certain fees from the Depositary, 
based on the Depositary’s revenues resulting from issuance and cancellation fees charged to ADR holders, net of 
custody and safe keeping costs. In addition, the Depositary has waived the cost of providing administrative and 
reporting services, and access charges in connection with the Company’s ADR Program. 
Fees paid in 2024 
In 2024, the Company received from the Depositary fees for an amount of $667 thousands corresponding to the 
period March 13, 2023 through March 12, 2024.  
Fees payable during 2025 
In 2025, the Company received from the Depositary fees for an amount of $848 thousands corresponding to the 
period March 13, 2024 through March 12, 2025.

Controls and Procedures 
Evaluation of Disclosure Controls and Procedures 
Under the supervision and with the participation of our management, including the Company’s chief executive 
officer and chief financial officer, we have evaluated the effectiveness of the design and operation of our 
disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange 
Act) as of December 31, 2024. 
Based on that evaluation, the Company’s chief executive officer and chief financial officer have concluded that, as 
of December 31, 2024, our disclosure controls and procedures are effective to ensure that information required to 
be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized 
and reported within the time periods specified in the SEC’s rules and forms and to ensure that such information is 
accumulated and communicated to management, including the Company’s chief executive officer and chief 
financial officer, to allow timely decisions regarding required disclosure. Our disclosure controls and procedures 
are designed to provide reasonable assurance of achieving their objectives. The Company’s chief executive officer 
and chief financial officer have concluded that our disclosure controls and procedures are effective at a reasonable 
assurance level. 
Management’s Report on Internal Control over Financial Reporting 
Management is responsible for establishing and maintaining adequate internal control over financial reporting (as 
such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial 
reporting was designed by management to provide reasonable assurance regarding the reliability of financial 
reporting and the preparation and fair presentation of its financial statements for external purposes in accordance 
with IFRS. 
In addition, under the Company’s articles of association, as supplemented by the audit committee’s charter, the 
audit committee assists the board of directors in fulfilling its oversight responsibilities relating to the effectiveness 
of the Company’s systems of internal control, risk management and internal audit over financial reporting. In 
particular, the audit committee is required to review the scope and results of the activities of the Company’s 
external auditors and the internal audit function relating to the Company’s internal control over financial 
reporting, and obtain reports on significant findings and recommendations; and is also required to assess, at least 
annually at the time the annual accounts are approved, the effectiveness of the Company’s systems of internal 
control and risk management over financial reporting. 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements or omissions. In addition, projections of any evaluation of effectiveness to future periods are 
subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate. 
On a yearly basis, management conducts its assessment of the effectiveness of Tenaris’s internal control over 
financial reporting based on the framework in Internal Control- Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission. 
On February 18, 2025, management reported to the audit committee of the Company’s board of directors that 
management had conducted its assessment of the effectiveness of the Company’s internal controls over financial 
reporting for the year ended December 31, 2024, and that, based on management’s evaluation and considering 
the inherent limitations to the effectiveness of any internal control system, management had concluded that the 
Company’s internal controls over financial reporting were effective as of December 31, 2024. 
Change in Internal Control over Financial Reporting 
There were no changes in our internal control over financial reporting (as such term is defined in Rules 13a -15(f) 
and 15d -15(f) under the Exchange Act) during the year ended December 31, 2024, that have materially affected, 
or are reasonably likely to materially affect, our internal control over financial reporting.

Audit Committee’s Pre-approval Policies and Procedures  
The Company’s Audit Committee is responsible for, among other things, the oversight of the Company’s external 
auditors. Under its charter, the audit committee is responsible to review the appropriateness of, and approve, in 
advance, the provision of any permissible non-audit services by the external auditors; and to review and approve 
any fees, whether for audit, audit-related, or non-audit services payable to the external auditors. 
The audit committee makes its recommendations to the shareholders’ meeting concerning the continuing 
appointment or termination of the Company’s external auditors. On a yearly basis, the audit committee reviews, 
together with management and the external auditor, the audit plan, audit related services and other permissible 
non-audit services and approves, ad-referendum of the general shareholders’ meeting, the related fees. With 
respect to non-audit services, the audit committee annually approves an estimated amount for undetermined 
non-audit services, conditioned upon final review and approval of such services by the audit committee. The audit 
committee annually receives from the external auditor the written disclosures required by PCAOB Rule 3524 
“Audit Committee Pre-Approval of Certain Tax Services”, together with a description of the scope of tax services 
for such year, and the external auditors’ confirmation that such non-audit services are consistent with the 
Sarbanes-Oxley Act, SEC Regulation S-X Rule 2-01, and applicable PCAOB rules. The Audit Committee did not 

Annual Report 2024

approve any fees pursuant to the de minimis exception to the pre-approval requirement provided by paragraph 
(c)(7)(i)(C) of Rule 2-01 of Regulation S-X during 2024 or 2023. 
The general shareholders’ meeting normally approves such audit fees and authorizes the audit committee to 
approve any increase or reallocation of such audit fees as may be necessary, appropriate or desirable under the 
circumstances. No services outside the scope of the audit committee’s approval may be undertaken by the 
external auditor.

Purchases of Equity Securities by the Company and Affiliated Purchasers 
On June 2, 2020, at the Company’s general meeting of shareholders, the Company’s shareholders authorized the 
Company and the Company’s subsidiaries to acquire, from time to time, shares, including shares represented by 
ADSs, on the terms and conditions set forth below. Although the validity period of such authorization will expire

2025, which will consider the renewal of such authorization for an additional five-year period. 
• 
Purchases, acquisitions or receipts of securities may be made in one or more transactions as the board of 
directors of the Company or the board of directors or other governing bodies of the relevant entity, as 
applicable, considers advisable. 
• 
The maximum number of securities acquired pursuant to this authorization may not exceed 10% of the 
Company’s issued shares or, in the case of acquisitions made through a stock exchange in which the 
securities are traded, such lower amount as may not be exceeded pursuant to any applicable laws or 
regulations of such market. The number of securities acquired as a block may amount to the maximum 
permitted amount of purchases. 
• 
The purchase price per share to be paid in cash may not exceed 125% (excluding transaction costs and 
expenses), nor may it be lower than 75% (excluding transaction costs and expenses), in each case of the 
average of the closing prices of the Company’s securities in the stock exchange through which the 
Company’s securities are acquired, during the five trading days in which transactions in the securities were 
recorded in such stock exchange preceding (but excluding) the day on which the Company’s securities are 
acquired. For over-the-counter or off-market transactions, the purchase price per ADS to be paid in cash 
may not exceed 125% (excluding transaction costs and expenses), nor may it be lower than 75% 
(excluding transaction costs and expenses), in each case of the average of the closing prices of the ADSs in 
the NYSE during the five trading days in which transactions in ADSs were recorded in the NYSE preceding 
(but excluding) the day on which the ADSs are acquired; and, in the case of acquisition of securities, other 
than in the form of ADSs, such maximum and minimum per security purchase prices shall be equal to the 
prices that would have applied in case of an ADS purchase pursuant to the formula above divided by the 
number of underlying shares represented by an ADS at the time of the relevant purchase. Compliance with 
maximum and minimum purchase price requirements in any and all acquisitions made pursuant to this 
authorization (including, without limitation, acquisitions carried out through the use of derivative financial 
instruments or option strategies) shall be determined on and as of the date on which the relevant 
transaction is entered into, irrespective of the date on which the transaction is to be settled. 
• 
The above maximum and minimum purchase prices shall, in the event of a change in the par value of the 
securities, a capital increase by means of a capitalization of reserves, a distribution of securities under 
compensation or similar programs, a stock split or reverse stock split, a distribution of reserves or any other 
assets, the redemption of capital, or any other transaction impacting on the Company’s equity, be adapted 
automatically, so that the impact of any such transaction on the value of the securities shall be reflected. 
• 
The acquisitions of securities may not have the effect of reducing the Company’s net assets below the sum 
of the Company’s share capital plus its undistributable reserves. 
• 
Only fully paid-up securities may be acquired pursuant to this authorization. 
• 
The acquisitions of securities may be carried out for any purpose, as may be permitted under applicable 
laws and regulations, including without limitation to reduce the share capital of the Company, to offer 
such shares to third parties in the context of corporate mergers or acquisitions of other entities or 
participating interests therein, for distribution to the Company’s or the Company’s subsidiaries’ directors, 
officers or employees or to meet obligations arising from convertible debt instruments. 
• 
The acquisitions of securities may be carried out by any and all means, as may be permitted under 
applicable laws and regulations, including through any stock exchange in which the Company’s securities 
are traded, through public offers to all shareholders of the Company to buy securities, through the use of 
derivative financial instruments or option strategies, or in over-the-counter or off-market transactions or in 
any other manner. 
• 
The acquisitions of securities may be carried out at any time, during the duration of the authorization, 
including during a tender offer period, as may be permitted under applicable laws and regulations. 

Annual Report 2024 
248

for under applicable Luxembourg law as in effect from time to time (such maximum period being, as of to 
date, 5 years). 
• 
The acquisitions of securities shall be made at such times and on such other terms and conditions as may 
be determined by the board of directors of the Company or the board of directors or other governing 
bodies of the relevant subsidiary, provided that, any such purchase shall comply with Article 430-15 et. seq. 
of the Luxembourg Company Law (or any successor law) and, in the case of acquisitions of securities made 
through a stock exchange in which the Company’s securities are traded, with any applicable laws and 
regulations of such market. 
 
Share buyback programs 
 
First share buyback program 
 
On November 1, 2023, the Company’s board of directors approved a share buyback program of up to $1.2 billion 
with the intention to cancel the shares acquired through the program. The share buyback program was carried 
out under the authority granted by the annual general meeting of shareholders held on June 2, 2020, to 
repurchase up to a maximum of 10% of the Company’s shares.  
 
For purposes of carrying out each tranche of the first share buyback program, the Company entered into non-
discretionary buyback agreements with a primary financial institutions, which made trading decisions concerning 
the timing of the purchases of the Company’s shares independently of and uninfluenced by the Company and 
acted in compliance with applicable rules and regulations, including the Market Abuse Regulation 596/2014 and 
the Commission Delegated Regulation (EU) 2016/1052. 
 
The first share buyback program was divided in four tranches and ran from November 5, 2023, to (and including) 
August 2, 2024. During the first share buyback program the Company repurchased 71,679,768 ordinary shares, 
representing 6.07% of the Company’s issued share capital at the beginning of the program, for a total 
consideration of $1.2 billion. 
 
The extraordinary meeting of shareholders held on April 30, 2024, approved the cancellation of 17,779,302 
ordinary shares held in treasury and acquired by the Company throughout the first tranche of the first share 
buyback program and the corresponding reduction of the Company’s issued share capital. Shares repurchased 
under the second, third and fourth tranche of the first share buyback program are held in treasury and will be 
cancelled in due course, as further described below. 
 
Second share buyback program 
 
On November 6, 2024, the Company’s board of directors approved a follow-on share buyback program of up to 
$700 million (excluding incidental transaction fees), subject to a maximum of 46,373,915 ordinary shares, 
representing the remaining 3.93% of the Company’s issued share capital (measured as of the launch of the first 
share buyback program), to complete the maximum of 10% of the share capital that may be repurchased by the 
Company, with the intention to cancel the shares acquired through the program. The share buyback program was 
carried out under the authority granted by the annual general meeting of shareholders held on June 2, 2020, to 
repurchase up to a maximum of 10% of the Company’s shares. 
 
For purposes of carrying out the second share buyback program, the Company entered into non-discretionary 
buyback agreements with primary financial institutions, which make trading decisions concerning the timing of 
the purchases of the Company’s shares independently of and uninfluenced by the Company and act in 
compliance with applicable rules and regulations, including the Market Abuse Regulation 596/2014 and the 
Commission Delegated Regulation (EU) 2016/1052. 
 
The second share buyback program ran from November 11, 2024, to (and including) March 4, 2025. During the 
follow-on share buyback program, the Company repurchased 36,862,132 ordinary shares, representing 3.12% of 
the Company’s issued share capital as measured at the beginning of the first program, for a total consideration of 
approximately $700 million. 
 
 

Annual Report 2024 
249 
 
During the years ended December 31, 2024 and 2023 the Company repurchased 83,616,548 and 12,648,091 
ordinary shares, respectively, for approximately $1.7 billion on an aggregate basis under both share buyback 
programs. During 2025, the Company repurchased a total of 12,277,261 ordinary shares, for a total 
consideration of approximately $0.2 billion. Total shares repurchased under the share buyback programs 
represented 9.19% of the issued share capital at the beginning of the first share buyback program. 
 
Shares repurchased during the second, third and fourth tranche of the first share buyback program and during 
the follow-on share buyback program are being held in treasury. The Company intends to cancel these treasury 
shares in the upcoming extraordinary general meeting of shareholders, scheduled to be held on May 6, 2025 
(immediately after the annual general meeting of shareholders) and to reduce the Company’s issued share capital 
accordingly.

Cybersecurity 
Risk Management, Strategy and Governance 
 
Under the Company’s articles of association, as supplemented by the audit committee’s charter, the audit 
committee assists the board of directors in fulfilling its oversight responsibilities relating to the effectiveness of the 
Company’s systems of internal control, risk management and internal audit over financial reporting. In addition, 
the Company has established a management-level Critical Risk Committee (“CRC”) that assists the Company’s 
board of directors, the audit committee and the chief executive officer in connection with the monitoring, 
assessment and review of risks to which Tenaris is exposed and in the oversight of the risk management 
framework and processes, with a focus on critical risks (including accidents, cybersecurity and obsolescence, 
commercial execution, environmental, health and safety and regulatory risks), the development of mitigating 
actions, and the monitoring of action plans. The CRC, which comprises several senior executives, risk assurance 
manager and general counsel, periodically reports to the Company’s board of directors, the audit committee and 
the chief executive officer on its activities. For more information on the audit committee and CRC, see “Risk 
Factors - Risks Relating to Our Business and Industry - Cyberattacks could have a material adverse impact on our 
business and results of operations”. 
In particular, with respect to cybersecurity risks, Tenaris has adopted a “Cybersecurity Risk Management 
Methodology”, which sets forth a procedure to monitor, identify, communicate, assess the impact and likelihood 
and report actual or potential risks affecting Tenaris’s information systems, including platform, networking and 
systems vulnerabilities, processes, sensitive information leak or loss. The objective of our Cybersecurity Risk 
Management Methodology is to reduce, accept, transfer, or avoid the effects of such risks thereby reducing 
accidents, harm, losses, disruption to services, or other negative impacts. Our risk assessment methodology 
considers the potential impact of cybersecurity risks with respect to continuity of operations, information security 
(including confidentiality, integrity and availability), financial performance, compliance or reputational effects, and 
health, safety and environment damages. In addition, the adopted methodology considers the probability of 
occurrence of each event based on factors that vary according to specific risks. A Cybersecurity Risk Catalog is 
used to register detected risks, document risk assessments, and adopt appropriate action plans and reporting 
measures. If deemed appropriate (for example, when specific knowledge is required) specialized consultants may 
be engaged in connection with cybersecurity risk processes. 
Tenaris has adopted certain other cybersecurity procedures that complement the above-mentioned Cybersecurity 
Risk Management Methodology and seek to effectively manage cybersecurity incidents by analyzing potential 
impacts, containing the attack, eradicating the threat, and recovering from the incident, instruct users of Tenaris’s 
information systems on how to respond to cybersecurity incidents involving or affecting Tenaris IT resources or 
devices through which users may access any Tenaris’s IT systems; and provide instructions and best practices to 
Tenaris’s personnel with system administrator’s roles in connection with cybersecurity incidents prevention, 
detection and response. In 2024, we adopted a process to assess third-parties cybersecurity, to the extent they are 
connected to Tenaris or process Tenaris’s confidential information. 
Tenaris has also adopted a “Ransomware Crisis Management Procedure” setting forth the procedure to timely 
and adequately respond to a ransomware incident. In addition, because a cybersecurity incident may escalate into 
a major company crisis, “Tenaris’s Crisis Management Procedure” is triggered and applied when certain events 
signal potential material impacts. 
Tenaris’s policies, processes and procedures established to detect and manage cybersecurity risks are monitored 
and coordinated by a team of experienced and recognized professionals, including a chief information security 
officer, a cybersecurity risk management director and a cybersecurity and security architecture director, with an 
average of more than 25 years of experience in cybersecurity and information technology fields. The chief 
information security officer periodically reports on its activities to the CRC. 
 
During 2024, no risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, or 
third-parties cybersecurity incidents, lead to known breaches of our business-critical IT systems and, as such, have 
not materially affected, or are reasonably likely to materially affect, Tenaris, including its business strategy, results 
of operations, or financial condition.  
 

Annual Report 2024 
254 
 
Tenaris has adopted cyber-resilience standards as part of its cybersecurity strategy and cyber capabilities. For 
example, a cyberattack simulation exercise was carried out in 2024 with an external consultant (KPMG) acting as a 
cyber attacker and Tenaris’s cybersecurity team acting as defenders, showing the Company’s strong commitment 
to cybersecurity issues, particularly associated risks, potential impacts and action plans. The results of such exercise 
are still subject to evaluation and will aid in building a stronger cybersecurity strategy. 
 
For more information on cybersecurity risks, see “Risk Factors - Risks Relating to Our Business and Industry - 
Cyberattacks could have a material adverse impact on our business and results of operations”.

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
271 
 
I. 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 Financial Statements to “Tenaris” refer to the Company and its consolidated subsidiaries. A 
list of the Company’s principal subsidiaries is included in note 33 to these Consolidated Financial Statements. 
 
The Company’s shares trade on the Italian Stock Exchange and the Mexican Stock Exchange; and the Company’s 
American Depositary Securities (“ADS”) trade on the New York Stock Exchange. 
 
These Consolidated Financial Statements were approved for issuance by the Company’s Board of Directors on 
February 19, 2025. The Board of Directors has the power to amend and reissue these Consolidated Financial 
Statements. 
 
II. ACCOUNTING POLICIES  
 
The accounting policies applied in the preparation of these Consolidated Financial Statements are set out below. 
These policies have been consistently applied to all the years presented, unless otherwise stated. 
 
 
A 
Basis of presentation 
 
The Consolidated Financial Statements of Tenaris have been prepared in accordance with International Financial 
Reporting Standards (“IFRS" or "IFRS Accounting Standards”), as issued by the International Accounting Standards 
Board (“IASB”) and in accordance with IFRS as adopted by the European Union, under the historical cost convention, 
as modified by the revaluation of certain financial assets and liabilities (including derivative instruments) and plan 
assets at fair value. The Consolidated Financial Statements are, unless otherwise noted, presented in thousands of 
U.S. dollars (“$”). 
 
Whenever necessary, certain comparative amounts have been reclassified to conform to changes in presentation in 
the current year.  
 
The preparation of Consolidated Financial Statements in conformity with IFRS requires management to make certain 
accounting estimates and assumptions that might affect among others, the reported amounts of assets, liabilities, 
contingent liabilities, revenues and expenses. Actual results may differ from these estimates. The main areas 
involving material estimates or judgements are: impairment testing of long-lived assets (notes II.H), impairment in 
investments in associates (note II.B); income taxes -including recoverability of deferred tax assets- (note II.O); 
obsolescence of inventory (note II.J); contingencies (note II.Q); allowance for trade receivables (note II.K); post-
employment and other long-term benefits (note II.P); business combinations (notes II.B); useful lives of property, 
plant and equipment and other long-lived assets (notes II.E, II.F, II.H), fair value estimation of certain financial 
instruments (note III.B) and property title ownership restriction (note IV.28). During the year there were no significant 
changes in the material accounting estimates and judgements. 
 
(1) 
Accounting pronouncements applicable as from January 1, 2024 
 
Accounting pronouncements that became effective during 2024 have no material effect on the Company’s financial 
condition or results of operations. 
 
The following amendments became effective as at 1 January 2024: 
▪ 
Classification of Liabilities as Current or Non-current and Non-current Liabilities with Covenants - 
Amendments to IAS 1. 
▪ 
Lease Liability in a Sale and Leaseback – Amendments to IFRS 16. 
▪ 
Disclosures: Supplier Finance Arrangements - Amendments to IAS 7 and IFRS 7.

For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
272 
 
(2) 
New accounting pronouncements not applicable as of December 31, 2024 
 
Amendments to IAS 21 – Lack of Exchangeability 
 
In August, 2023, the IASB published “Lack of Exchangeability (Amendments to IAS 21)” with new guidance to 
determine when a currency is exchangeable or not, and how to determine the exchange rate to apply when a 
currency is not exchangeable. The amendments also require the disclosure of additional information when a 
currency is not exchangeable.  
 
The amendments are effective for annual periods beginning on or after January 1, 2025 with early adoption 
permitted and without retrospective application. 
 
The Company does not expect these amendments to have a material impact on its operations or financial 
statements. 
 
IFRS 18 - Presentation and Disclosures in Financial Statements 
 
In April 2024, the IASB published IFRS 18, that will replace IAS 1 “Presentation of financial statements”. IFRS 18 
introduces new requirements that will help to achieve comparability of the financial performance of similar entities 
and provide more relevant information and transparency to users. Even though IFRS 18 will not impact the 
recognition or measurement of items in the financial statements, its impacts on presentation and disclosure are 
expected to be extensive, in particular those related to the income statement, statement of financial position, 
statement of cash flows and the inclusion of management-defined performance measures within the financial 
statements. 
 
Management is currently assessing the detailed implications of applying the new standard on the Consolidated 
Financial Statements.  
 
The group will apply the new standard from its mandatory effective date of 1 January 2027. Retrospective 
application is required, and so the comparative information for the financial year ending December 31, 2026 and 
December 31, 2025 will be restated in accordance with IFRS 18. The European Union has still not endorsed this 
standard. 
 
Other newly published accounting standards, amendments to accounting standards and interpretations are not 
mandatory for December 31, 2024 reporting periods and have not been early adopted by the Company. These 
standards, amendments or interpretations are not expected to have a material impact in the current or future 
reporting periods and on foreseeable future transactions. 
 
 
B 
Group accounting 
 
(1) 
Subsidiaries and transactions with non-controlling interests  
 
Subsidiaries are all entities over which Tenaris has control. Tenaris controls an entity when it is exposed to, or has 
rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its 
power over the entity. In some cases, the Company considers that it has the ability to affect returns through its 
power over an entity even if it holds less than 50% of the shares or voting rights of the subsidiary because it is able 
to prevail at all of the subsidiary’s general meetings, which in turn allows Tenaris to nominate and appoint a majority 
of the subsidiary’s board of directors. Subsidiaries are fully consolidated from the date on which control is obtained 
by the Company and are no longer consolidated from the date control ceases. 
 
The acquisition method is used to account for the acquisition of subsidiaries by Tenaris. The cost of an acquisition 
is measured as the fair value of the assets transferred, equity instruments issued and liabilities incurred or assumed 
at the date of exchange. Acquisition-related costs are expensed as incurred. Identifiable assets acquired, liabilities 
and contingent liabilities assumed in a business combination are generally measured initially at their fair values at 
the acquisition date. Any non-controlling interest in the acquiree is measured either at fair value or at the non-
controlling interest’s proportionate share of the acquiree’s net identifiable assets. The excess of the aggregate of 
the consideration transferred and the amount of any non-controlling interest in the acquiree over the fair value of 
the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the 
subsidiary acquired, the difference is recognized directly in the Consolidated Income Statement as bargain purchase. 
 
 
Contingent consideration is classified either as equity or as a financial liability. Amounts classified as a financial 
liability are subsequently remeasured at fair value through profit or loss.  
 

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
273 
 
If the business combination is achieved in stages, the acquisition date carrying value of the acquirer’s previously 
held equity interest in the acquiree is remeasured to fair value at the acquisition date. Any gains or losses arising 
from such remeasurement are recognized in profit or loss. 
 
Transactions with non-controlling interests that do not result in a loss of control are accounted as transactions with 
equity owners of the Company. For purchases from non-controlling interests, the difference between any 
consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded 
in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.  
 
When the Company ceases to have control or significant influence, any retained interest in the entity is remeasured 
to its fair value and the change in carrying amount, net of consideration received (if any), recognized in profit or 
loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest 
as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other 
comprehensive income in respect of that entity are accounted for as if the group had directly disposed of the related 
assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are 
reclassified to profit or loss.  
 
Material intercompany transactions, balances and unrealized gains (losses) on transactions between Tenaris 
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 intercompany transactions are generated. 
These are included in the Consolidated Income Statement under Other financial results.  
 
(2) 
Non-consolidated companies 
 
Investments in non-consolidated companies (associates and joint ventures), which generally involve a shareholding 
of between 20% and 50% of the voting rights, are accounted for by the equity method and are initially recognized 
at cost (as defined by IAS 28, “Investments in Associates and Joint Ventures”). The Company’s investment in non-
consolidated companies includes goodwill identified in acquisition, net of any accumulated impairment loss. 
 
Associated companies are those entities in which Tenaris exerts significant influence in accordance with IFRS, but 
does not have control. 
 
Joint arrangements are combinations in which there are contractual agreements by virtue of which two or more 
partner companies hold an interest in one or more companies that undertake operations or hold assets in such a 
way that any financial or operating decision is subject to the unanimous consent of the partners (as defined by IFRS 
11 “Joint Arrangements”). A joint arrangement is classed as a joint operation if the parties hold rights to its assets 
and have obligations in respect of its liabilities or as a joint venture if the venturers hold rights only to the investee's 
net assets. 
 
Under the equity method of accounting, investments are initially recognized at cost and adjusted thereafter to 
recognize Tenaris’s share of the post-acquisition profits or losses of the investee in profit or loss, and Tenaris’s share 
of movements in other comprehensive income of the investee in other comprehensive income. Dividends received 
or receivable from associates and joint ventures are recognized as a reduction in the carrying amount of the 
investment. 
 
If material, unrealized results on transactions between Tenaris and its non-consolidated companies are eliminated 
to the extent of Tenaris’s interest in the non-consolidated companies. Unrealized losses are also eliminated unless 
the transaction provides evidence of an impairment indicator of the asset transferred. Financial statements of non-
consolidated companies are adjusted where necessary to ensure consistency with IFRS. 
 
The Company’s pro-rata share of earnings in non-consolidated companies is recorded in the Consolidated Income 
Statement under Equity in earnings of non-consolidated companies. The Company’s pro-rata share of changes in 
other comprehensive income is recognized in the Consolidated Statement of Comprehensive Income. 
 
 

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
274 
 
The main investments in non-consolidated companies are: 
  
a) Ternium 
  
At December 31, 2024, Tenaris held 11.46% in the share capital of Ternium S.A. (“Ternium”) representing 
11.70% of its outstanding shares. The following factors and circumstances evidence that Tenaris has significant 
influence over Ternium: 
  
▪ four out of eight members of Ternium’s board of directors (including Ternium’s chairman) are also members 
of the Company’s board of directors; and 
▪ both the Company and Ternium are under the indirect common control of San Faustin S.A. (“San Faustin”) 
and under the shareholders’ agreement by and between the Company and Techint Holdings S.àr.l ("Techint"), 
a wholly owned subsidiary of San Faustin and Ternium’s controlling shareholder, dated January 9, 2006 
Techint, is required to take actions within its power to cause (a) one of the members of Ternium’s board of 
directors to be nominated by the Company and (b) any director nominated by the Company to be removed 
from Ternium’s board of directors only pursuant to previous written instructions of the Company. 
 
b) Usiminas 
 
At December 31, 2024, Tenaris held, through its Brazilian subsidiary Confab Industrial S.A. (“Confab”), 47.5 
million ordinary shares and 1.3 million preferred shares of Usinas Siderúrgicas de Minas Gerais S.A. - Usiminas 
(“Usiminas”), representing 6.76% of its shares with voting rights and 3.96% of its total share capital.  
 
Confab’s participation in Usiminas share capital is the result of a series of acquisitions, the first of which was 
performed on January 16, 2012, pursuant to which Ternium (through certain of its subsidiaries) and Confab 
acquired a large block of Usiminas ordinary shares and joined Usiminas’ existing control group. Subsequently, in 
2016, Ternium and Confab subscribed to additional ordinary shares and to preferred shares.  
 
On March 30, 2023, Confab, together with Ternium (through its subsidiaries Ternium Investments and Ternium 
Argentina), agreed to acquire an additional 68.7 million ordinary shares of Usiminas at a price of BRL10 per 
ordinary share. The transaction closed on July 3, 2023, and was financed with cash on hand. Tenaris paid 
approximately BRL110 million (approximately $22.7 million) in cash for approximately 11 million ordinary shares, 
increasing its participation in the Usiminas control group to 9.8%. 
 
The Usiminas control group comprises the T/T Group, formed by Ternium Investments, Ternium Argentina and 
Confab; the NSC Group, comprising Nippon Steel Corporation, Mitsubishi and MetalOne; and Usiminas’ employee 
pension fund, Previdência Usiminas. At December 31, 2024, the Usiminas control group held, in the aggregate, 
483.6 million ordinary shares, representing approximately 68.6% of Usiminas’ voting capital and the T/T Group 
held an aggregate participation of 61.3% in the control group (with 51.5% of the control group’s participation 
corresponding to Ternium’s subsidiaries, and remaining 9.8% corresponding to Confab); the NSC Group and 
Previdência Usiminas held 31.7% and 7%, respectively, in the control group. 
 
Upon closing of the July 3, 2023 acquisition, the then existing Usiminas shareholders agreement governing the 
relationship between the T/T Group, the NSC Group and Previdência Usiminas was replaced by a new shareholders 
agreement setting forth a new governance structure for Usiminas. The T/T Group is now entitled to nominate a 
majority of the Usiminas board of directors, the chief executive officer and four other members of the Usiminas 
board of officers. Of the positions allocated to the T/T Group, Tenaris retains the right to nominate one member 
of the Usiminas board of directors and one member of the Usiminas board of officers. Ordinary decisions may be 
approved with a 55% majority of Usiminas’ control group shares.  
 
At any time after the second anniversary of the closing of the transaction, the T/T Group will have the right to buy 
the NSC Group’s remaining interest in the Usiminas’ control group (153.1 million ordinary shares) at the higher 
of $2.0584 per share and the equivalent in U.S. dollars of the 40-trading day average price per share immediately 
prior to the date of exercising the option. In addition, the NSC Group will have the right, at any time after the 
closing of the transaction, to withdraw its remaining shares from the control group and sell them in the open 
market after giving the T/T Group the opportunity to buy them at the equivalent in U.S. dollars of the 40-trading 
day average price per share immediately prior to the NSC group’s notice of withdrawal, as well as the right, at 
any time after the second anniversary of the closing, to sell such shares to the T/T Group at $2.0584 per share. 
Confab will have the right (but not the obligation) to participate in each such transaction pro rata to its current 
participation in the T/T Group.

Confab and the Ternium entities party to the Usiminas shareholders agreement have a separate shareholders 
agreement governing their respective rights and obligations as members of the T/T Group. Under such separate 
agreement, Confab enjoys certain rights with respect to the governance of Usiminas, including, among others, 
the ability to nominate certain Usiminas’ officers and directors. Those circumstances evidence that Tenaris 
continues having significant influence over Usiminas and, as a result, continues accounting for its investment 
under the equity method. 
 
c) 
Techgen 
 
Techgen S.A. de C.V. (“Techgen”), which operates an electric power plant in Mexico, is a joint venture company 
owned 48% by Ternium, 30% by Tecpetrol International S.A. (“Tecpetrol”) and 22% by Tenaris. The Company, 
Ternium and Tecpetrol are parties to a shareholders’ agreement relating to the governance of Techgen and are 
under the indirect common control of San Faustin. Based on the facts stated above, the Company has determined 
that it has significant influence over this entity. 
 
Tenaris carries its investments in non-consolidated companies under the equity method, with no additional goodwill 
or intangible assets recognized. Tenaris reviews investments in non-consolidated companies for impairment 
whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. For 
more information see note 14 to these Consolidated Financial Statements. 
 
 
C 
Segment information 
 
The Company is organized in one major business segment, Tubes, which is also the reportable operating segment. 
All other business activities and operating segments that are not required to be separately reported are disclosed in 
the Other segment. 
 
The Tubes segment includes the production and sale of steel tubular products and related services mainly for the 
oil and gas industry, particularly oil country tubular goods (“OCTG”) used in drilling operations, and for other 
industrial applications with production processes that consist in the transformation of steel into tubular products. 
Business activities included in this segment are mainly dependent on the worldwide oil and gas industry, as this 
industry is a major consumer of steel pipe products, particularly OCTG used in drilling activities. Demand for steel 
pipe products from the oil and gas industry has historically been volatile and depends primarily upon the number 
of oil and natural gas wells being drilled, completed and reworked, and the depth and drilling conditions of these 
wells. Sales are generally made to end users, with exports being done through a centrally managed global 
distribution network and domestic sales are made through local subsidiaries. 
 
The Other segment includes all business activities related to the production and selling of sucker rods, coiled tubing, 
tubes used for plumbing and construction applications, oilfield / hydraulic fracturing services and others as energy 
and raw materials that exceed internal requirements. 
 
During 2024 and following the acquisition of Mattr’s pipe coating business unit on November 30, 2023, the 
management performed a review of the new business structure to decide on the allocation of resources and the 
assessment of performance, and decided to integrate the coating activities to its Tubes segment. 
 
Tenaris’s Chief Operating Decision Maker (“CODM”) reviews operating and financial performance information with 
senior management on a monthly basis. This information differs from IFRS principally as follows: 
 
▪ 
the use of direct cost methodology to calculate the inventories, while under IFRS it is at full cost, including 
absorption of production overheads and depreciation; 
▪ 
the use of costs based on previously internally defined cost estimates, while, under IFRS, costs are calculated at 
historical cost, mainly on a FIFO basis; 
▪ 
any currency translation adjustment reclassification, when applicable, for companies that under IFRS had a 
different functional currency than the U.S. dollar; and 
▪ 
other timing differences, if any. 
 
Tenaris presents its geographical information in four areas: North America, South America, Europe and Asia Pacific, 
Middle East and Africa. For purposes of reporting geographical information, net sales are allocated to geographical 
areas based on the customer’s location; the allocation of assets is based on their geographical location.

D 
Foreign currency translation  
 
(1) 
Functional and presentation currency 
 
IAS 21, “The effects of changes in foreign exchange rates” defines the functional currency as the currency of the 
primary economic environment in which an entity operates. 
 
The functional and presentation currency of the Company is the U.S. dollar. The U.S. dollar is the currency that best 
reflects the economic substance of the underlying events and circumstances relevant to Tenaris’s global operations.  
 
Starting January 1, 2023, the Company changed the functional currency of its Brazilian subsidiaries, from the 
Brazilian Real to the U.S. dollar. 
 
Except for the Italian subsidiaries whose functional currency is the Euro and two subsidiaries whose functional 
currencies are the Canadian Dollar and the Norwegian Krone, Tenaris determined that the functional currency of 
its other subsidiaries is the U.S. dollar, based on the following principal considerations: 
 
▪ 
sales are mainly negotiated, denominated and / or settled in U.S. dollars. If priced in a currency other than the 
U.S. dollar, the sales price may consider exposure to fluctuation in the exchange rate against the U.S. dollar; 
▪ 
prices of their critical raw materials and inputs are priced and / or settled in U.S. dollars;  
▪ 
transaction and operational environment and the cash flow of these operations have the U.S. dollar as reference 
currency;  
▪ 
there is a significant level of integration of the local operations within Tenaris’s international global distribution 
network; and 
▪ 
net financial assets and liabilities are mainly received and maintained in U.S. dollars. 
 
(2) 
Transactions in currencies other than the functional currency 
 
Transactions in currencies other than the functional currency are translated into the functional currency using the 
exchange rates prevailing at the date of the transactions or valuation where items are re-measured. 
 
At the end of each reporting period: (i) monetary items denominated in currencies other than the functional currency 
are translated using the closing rates; (ii) non-monetary items that are measured in terms of historical cost in a 
currency other than the functional currency are translated using the exchange rates prevailing at the date of the 
transactions; and (iii) non-monetary items that are measured at fair value in a currency other than the functional 
currency are translated using the exchange rates prevailing at the date when the fair value was determined. 
 
Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at 
year-end exchange rates of monetary assets and liabilities denominated in currencies other than the functional 
currency are recorded as gains and losses from foreign exchange and included in Other financial results in the 
Consolidated Income Statement, except when deferred in equity as qualifying cash flow hedges and qualifying net 
investment hedges. 
 
(3) 
Translation of financial information in currencies other than the functional currency 
 
Results of operations for subsidiaries whose functional currencies are not the U.S. dollar are translated into U.S. 
dollars at the average exchange rates for each quarter of the year. Financial statement positions are translated at 
the period-end exchange rates. Translation differences are recognized in a separate component of equity as 
Currency Translation Adjustment. In the case of a sale or other disposal of any of such subsidiaries, any accumulated 
translation difference would be recognized in the Consolidated Income Statement as a gain or loss from the sale or 
disposal following IAS 21. 
 
Goodwill and fair value adjustments arising from the acquisition of a foreign operation are treated as assets and 
liabilities of the foreign operation and translated at the closing exchange rate.

E 
Property, plant and equipment  
 
Property, plant and equipment are recognized at historical acquisition or construction cost less accumulated 
depreciation and impairment losses. Historical cost includes expenditure that is directly attributable to the acquisition 
of the items. Property, plant and equipment acquired through acquisitions accounted for as business combinations 
have been valued initially at the fair market value of the assets acquired. 
 
Major overhaul and rebuilding expenditures are capitalized as property, plant and equipment only when it is 
probable that future economic benefits associated with the item will flow to the Company and the investment 
enhances the condition of assets beyond its original condition. The carrying amount of any replaced parts is 
derecognized. Maintenance expenses on manufacturing properties are recorded as cost of products sold in the year 
in which they are incurred. 
 
Cost may also include transfers from equity of any gains or losses on qualifying cash flow hedges of foreign currency 
purchases of property, plant and equipment.  
 
Borrowing costs that are attributable to the acquisition or construction of certain capital assets are capitalized as 
part of the cost of the asset, in accordance with IAS 23, “Borrowing Costs”. Assets for which borrowing costs are 
capitalized are those that require a substantial period of time to prepare for their intended use.  
 
 
The depreciation method is reviewed at each year end. Depreciation is calculated using the straight-line method to 
depreciate the cost of each asset to its residual value over its estimated useful life, as follows:  
 
 
Land 
No Depreciation 
 
Buildings and improvements 
 
30-50 years 
 
Plant and production equipment 
 
10-40 years 
 
Vehicles, furniture and fixtures, and other equipment 
   4-10 years 
 
The assets’ residual values and useful lives of significant plant and production equipment are reviewed and adjusted, 
if appropriate, at each year-end date. An asset’s carrying amount is written down to its recoverable amount if the 
asset’s carrying amount is greater than its estimated recoverable amount. 
 
Management’s re-estimation of assets useful lives, performed in accordance with IAS 16, “Property, Plant and 
Equipment”, resulted in additional depreciation expenses of approximately $25.2 million in 2024, did not materially 
affect depreciation expenses in 2023 and resulted in additional depreciation expenses of approximately $39.1 
million in 2022. 
 
Tenaris depreciates each significant part of an item of property, plant and equipment for its different production 
facilities that (i) can be properly identified as an independent component with a cost that is significant in relation to 
the total cost of the item, and (ii) has a useful operating life that is different from another significant part of that 
same item of property, plant and equipment. 
 
Gains and losses on disposals are determined by comparing the proceeds with the carrying amount of assets and 
are recognized under Other operating income or Other operating expenses in the Consolidated Income Statement. 
 
 
F 
Intangible assets 
 
(1) 
Goodwill  
 
Goodwill represents the excess of the acquisition cost over the fair value of Tenaris’s share of net identifiable assets 
acquired as part of business combinations determined mainly by independent valuations. Goodwill is tested at least 
annually for impairment and carried at cost less accumulated impairment losses. Impairment losses on goodwill are 
not reversed. Goodwill is included in the Consolidated Statement of Financial Position under Intangible assets, net. 
 
For the purpose of impairment testing, goodwill is allocated to a cash generating unit (“CGU”) or group of CGUs 
that are expected to benefit from the business combination which generated the goodwill being tested.

(2) 
Information systems projects 
 
Costs associated with maintaining computer software programs are generally recognized as an expense as incurred. 
However, costs directly related to the development, acquisition and implementation of information systems are 
recognized as intangible assets if it is probable that they have economic benefits exceeding one year and comply 
with the recognition criteria of IAS 38, “Intangible Assets”. 
 
Information systems projects recognized as assets are amortized using the straight-line method over their useful 
lives, generally not exceeding a period of 3 years. Amortization charges are mainly classified as Selling, general and 
administrative expenses in the Consolidated Income Statement.  
 
Management’s re-estimation of assets useful lives, performed in accordance with IAS 38, did not materially affect 
amortization expenses for the years 2024, 2023 and 2022.  
 
(3) 
Licenses, patents, trademarks and proprietary technology  
 
Licenses, patents, trademarks, and proprietary technology are initially recognized at cost, or at fair value at the 
acquisition date in case of a business combination. Licenses, patents, proprietary technology and those trademarks 
that have a finite useful life are carried at cost less accumulated amortization. Amortization is calculated using the 
straight-line method to allocate the cost over their estimated useful lives, which are in the range between 3 and 20 
years. Amortization charges are mainly classified as Cost of sales in the Consolidated Income Statement.  
 
The balance of acquired trademarks that have indefinite useful lives according to external appraisal amounts to 
$86.7 million at December 31, 2024, 2023 and 2022, and are included in Hydril CGU. Main factors considered in 
the determination of the indefinite useful lives include the years that they have been in service and their recognition 
among customers in the industry. 
 
Management’s re-estimation of assets useful lives, performed in accordance with IAS 38, did not materially affect 
amortization expenses for the years 2024, 2023 and 2022. 
 
(4) 
Research and development 
 
Research expenditures as well as development costs that do not fulfill the criteria for capitalization are recorded as 
Cost of sales in the Consolidated Income Statement as incurred. Research and development expenditures included 
in Cost of sales for the years 2024, 2023 and 2022 totaled $74.2 million, $60.0 million and $50.7 million, 
respectively.  
 
Capitalized costs were not material for the years 2024, 2023 and 2022. 
 
(5)  
Customer relationships 
 
In accordance with IFRS 3, "Business Combinations" and IAS 38, Tenaris has recognized the value of customer 
relationships separately from goodwill attributable to the acquisition of Maverick Tube Corporation (“Maverick”) and 
Hydril Company (“Hydril”) groups, Saudi Steel Pipe Co. (“SSPC”), Ipsco Tubulars Inc. (“IPSCO”) and the more recent 
acquisition of Mattr’s pipe coating business unit. 
 
Customer relationships acquired in a business combination are recognized at fair value at the acquisition date, have a 
finite useful life and are carried at cost less accumulated amortization. Amortization is calculated using the straight 
line method over the initial expected useful lives which were approximately 14 years for Maverick, 10 years for Hydril, 
9 years for SSPC, 3 years for IPSCO, and 4 months for Mattr’s pipe coating business unit. 
 
Management’s re-estimation of customer relationships useful lives, performed in accordance with IAS 38, did not 
affect amortization expenses for the years 2024 and 2023. 
 
In 2022, the Company reviewed the useful life of SSPC’s customer relationships and decided to reduce it from 5 years 
to 3 years, consequently a higher amortization charge of approximately $4.1 million was recorded in the Consolidated 
Income Statement under Selling, general and administrative expenses for the year ended December 31, 2022. 
 
As of December 31, 2024 the net book value of SSPC’s customer relationship amounted to $11.3 million, with a 
residual useful life of 9 months, while the other customer relationships were fully amortized.

G 
Right-of-use assets and lease liabilities 
 
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 principal 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 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 the 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. 
 
In determining the lease term, management considers all facts and circumstances that create an economic incentive 
to exercise an extension option or early termination, or not to 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). 
 
Payments associated with short-term leases, variable leases and leases of low value assets are recognized on a 
straight-line basis as expenses in profit or loss. Short-term leases are leases with a lease term of 12 months or less. 
 
 
H 
Impairment of non-financial assets 
 
Long-lived assets including identifiable intangible assets are reviewed for impairment at the lowest level for which 
there are separately identifiable cash flows, or CGU. Most of the Company’s principal subsidiaries that constitute a 
CGU have a single main production facility and, accordingly, each of such subsidiaries represents the lowest level 
of asset aggregation that generates largely independent cash inflows. 
 
Assets that are subject to amortization or depreciation are reviewed for impairment whenever events or changes in 
circumstances indicate that the carrying amount may not be recoverable. Intangible assets with indefinite useful 
lives, including goodwill, are subject to at least an annual impairment test, or are tested more frequently if events 
or circumstances indicate that the carrying amount value may be impaired. In some situations where there have not 
been significant changes to CGU assets and liabilities as well as external and internal events and circumstances 
which could materially alter the recoverable amount of the CGU, the most recent detailed calculation of recoverable 
amount made in a preceding period may be used in the impairment test for that CGU in the current period.  
 
For purposes of assessing key assumptions, the Company uses external sources of information and management 
judgment based on past experience and expectations. Material facts and circumstances specifically considered in 
the analysis usually include the discount rate used in Tenaris’s cash flow projections and the business condition in 
terms of competitive, economic and regulatory factors, such as the cost of raw materials, oil and gas prices, and 
the evolution of the rig count. Tenaris’s main source of revenue is the sale of products and services to the oil and 
gas industry, and the level of such sales is sensitive to international oil and gas prices and their impact on drilling 
activities.  
 
Management has determined the value of each of the key assumptions as follows: 
 
- Discount rate: based on the applicable weighted average cost of capital (“WACC”), which is considered to be a 
good indicator of capital cost, taking into account the industry, country and size of the business. For each CGU 
where assets are allocated, a specific WACC was determined. 
 
- Growth rate: considers mainly the inflation impact on prices and costs, the long-term evolution of the oil and gas 
industry, the higher demand to offset depletion of existing fields and the Company’s expected market penetration.  

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
280 
 
- Oil and gas prices: based on industry analysts’ reports and management’s expectations of market development. 
 
- Rig count: based on information published by Baker Hughes and management’s expectations. 
 
- Raw material costs: based on industry analysts’ reports and management’s expectations. 
 
An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable 
amount. The recoverable amount is the higher between the asset’s value in use and fair value less costs of disposal. 
Any impairment loss is allocated to reduce the carrying amount of the assets of the CGU in the following order: 
 
(a) first, to reduce the carrying amount of any goodwill allocated to the CGU; and 
(b) then, to the other assets of the unit (group of units) pro-rata on the basis of the carrying amount of each 
asset in the unit (group of units), considering not to reduce the carrying amount of the asset below the 
highest of its fair value less cost of disposal, its value in use or zero. 
 
Value in use is calculated by discounting the estimated cash flows over a five year period (or higher if the period 
can be justified) based on forecasts approved by management. For the subsequent years beyond the five-year 
period, a terminal value is calculated based on perpetuity considering a nominal growth rate of 2% taking into 
account among others, mainly the historical inflation rate. 
 
For purposes of calculating the fair value less costs of disposal, Tenaris uses the estimated value of future cash flows 
that a market participant could generate from the corresponding CGU.  
 
Management judgment is required to estimate discounted future cash flows. Actual cash flows and values could 
vary significantly from the forecasted future cash flows and related values derived using discounting techniques. 
 
Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal at each 
reporting date. For more information on impairment charges see note 5 to these Consolidated Financial Statements.  
 
 
I  
Other investments 
 
Other investments consist primarily of investments in financial instruments and time deposits with a maturity of 
more than three months at the date of purchase. 
 
Certain non-derivative financial assets that the Company held not for trading have been categorized as financial 
assets at fair value through other comprehensive income (“FVOCI”), as the business model objective is achieved by 
both holding financial assets in order to collect contractual cash flows and selling financial assets. They are carried 
at fair value and interest income from these financial assets is included in finance income using the effective interest 
rate method. Unrealized gains or losses are recorded as a fair value adjustment in the Consolidated Statement of 
Comprehensive Income and transferred to the Consolidated Income Statement when the financial asset is disposed. 
Exchange gains and losses and impairments related to the financial assets are immediately recognized in the 
Consolidated Income Statement. FVOCI instruments with maturities greater than 12 months after the balance sheet 
date are included in non-current assets. 
 
Other investments in financial instruments and time deposits are categorized as financial assets at fair value through 
profit or loss (“FVPL”) because such investments are held for trading and their performance is evaluated on a fair 
value basis. The results of these investments are recognized in Financial Results in the Consolidated Income 
Statement. 
 
Purchases and sales of financial investments are recognized as of their settlement date. 
 
The fair values of quoted investments are generally based on current bid prices. If the market for a financial investment 
is not active or the securities are not listed, Tenaris estimates the fair value by using standard valuation techniques. See 
section III Financial Risk Management.

J 
Inventories 
 
Inventories are stated at the lower between cost and net realizable value. The cost of finished goods and goods in 
process is comprised of raw materials, direct labor, utilities, freights and other direct costs and related production 
overhead costs, and it excludes borrowing costs. The allocation of fixed production costs, including depreciation 
and amortization charges, is based on the normal level of production capacity. Inventories cost is mainly based on 
the FIFO method. Tenaris estimates the net realizable value of inventories by grouping, where applicable, similar or 
related items. Net realizable value is the estimated selling price in the ordinary course of business, less any estimated 
costs of completion and selling expenses. Goods in transit as of year-end are valued based on the supplier’s invoice 
cost. 
 
Tenaris establishes an allowance for obsolete or slow-moving inventories related to finished goods, supplies and 
spare parts. For slow moving or obsolete finished products, an allowance is established based on management’s 
analysis of product aging. An allowance for obsolete and slow-moving inventory of supplies and spare parts is 
established based on management's analysis of such items to be used as intended and the consideration of potential 
obsolescence due to technological changes, aging and consumption patterns. 
 
 
K 
Trade and other receivables 
 
Trade and other receivables are recognized initially at fair value that corresponds to the amount of consideration that 
is unconditional unless they contain significant financing components. The Company holds trade receivables with the 
objective to collect the contractual cash flows and therefore measures them subsequently at amortized cost using the 
effective interest method. Due to their short-term nature, their carrying amount is considered to be the same as their 
fair value. 
 
Tenaris applies the IFRS 9 “Financial Instruments” simplified approach to measure expected credit losses, which uses 
a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables 
have been grouped based on shared credit risk characteristics and the days past due. The expected loss rates are based 
on the payment profiles of sales over a period of three years and the corresponding historical credit losses experienced 
within this period. The expected loss allowance also reflects current and forward-looking information on 
macroeconomic factors affecting the ability of each customer to settle the receivables. 
 
A credit account is typically considered in default when the customer has failed to make the required minimum 
payments for an extended period of time. Management considerations, including customer-specific analyses, are 
carried out to determine if an allowance has to be allocated to the credit. Following impairment, collection is monitored 
and reversed in case of receipt of the payment. 
 
 
L 
Cash and cash equivalents 
 
Cash and cash equivalents are comprised of cash at banks, liquidity funds and short-term investments with a maturity 
of less than three months at the date of purchase which are readily convertible to known amounts of cash which are 
subject to an insignificant risk of changes in value. Assets recorded in cash and cash equivalents are carried at fair 
market value or at historical cost which approximates fair market value. 
 
In the Consolidated Statement of Financial Position, bank overdrafts are included in Borrowings in current liabilities. 
 
For the purposes of the Consolidated Statement of Cash Flows, Cash and cash equivalents includes overdrafts.

Dividends may be paid by the Company to the extent that it has distributable retained earnings, calculated in 
accordance with Luxembourg law. See note 27 (iii) to these Consolidated Financial Statements. 
 
 
N 
Borrowings 
 
Borrowings are recognized initially at fair value net of transaction costs incurred and subsequently measured at 
amortized cost. Any difference between the proceeds (net of transaction costs) and the redemption amount is 
recognized in profit or loss over the period of the borrowings using the effective interest method. 
 
 
O 
Current and deferred income tax 
 
The income tax expense or credit for the period is the tax payable or recoverable on the current period’s taxable 
income based on the applicable income tax rate for each jurisdiction adjusted by changes in deferred tax assets and 
liabilities attributable to temporary differences and to unused tax losses. Both current and deferred tax are 
recognized in the Consolidated Income Statement, in Income tax, except to the extent that it relates to items 
recognized in other comprehensive income or directly in equity. In these cases, the tax is also recognized in other 
comprehensive income or directly in equity, respectively. 
 
The current income tax charge is calculated based on the tax laws enacted or substantively enacted at the reporting 
date in the countries where the Company’s subsidiaries operate and generate taxable income. 
 
 

Consolidated Financial Statements

283 
 
Deferred income tax is recognized applying the liability method on temporary differences arising between the tax 
bases of assets and liabilities and their carrying amounts in the financial statements. The temporary differences arise 
mainly from net operating loss carry-forwards, the effect of currency translation on depreciable fixed assets and 
inventories, depreciation on property, plant and equipment, valuation of inventories, provisions for post-
employment benefits and other long-term employee benefits and fair value adjustments of assets acquired in 
business combinations. However, deferred tax liabilities are not recognized if they arise from the initial recognition 
of goodwill. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period 
when the asset is realized or the liability is settled, based on tax laws that have been enacted or substantively 
enacted by the end of the reporting period.  
 
Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax 
regulation is subject to interpretation and considers whether it is probable that a taxation authority will accept an 
uncertain tax treatment. The Company measures its tax balances either based on the most likely amount or the 
expected value, depending on which method provides a better prediction of the resolution of the uncertainty. 
 
Deferred tax assets are recognized to the extent that it is probable that future taxable profits will be available against 
which the temporary differences and losses can be utilized. At the end of each reporting period, Tenaris reassesses 
unrecognized deferred tax assets. Tenaris recognizes a previously unrecognized deferred tax asset to the extent that 
it has become probable that future taxable income will allow the deferred tax asset to be recovered. 
 
Deferred tax assets and liabilities are not recognized for temporary differences arising from the carrying amount 
and tax basis of investments in subsidiaries, branches and associates, and interests in joint ventures, if the Company 
is able to control the timing of the reversal of the temporary differences and it is probable that the differences will 
not reverse in the foreseeable future. 
 
Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and 
liabilities and when the deferred tax balances relate to the same taxation authority. Current tax assets and tax 
liabilities are offset where the entity has a legally enforceable right to offset and intends either to settle on a net 
basis, or to realize the asset and settle the liability simultaneously.  
 
Deferred tax assets and liabilities are re-measured if tax rates change. These amounts are charged or credited to the 
Consolidated Income Statement or to the item Other comprehensive income in the Consolidated Statement of 
Comprehensive Income, depending on the account to which the original amount was charged or credited. 
 
On December 20, 2023, Pillar Two legislation was adopted in Luxembourg, and came into effect as from January 
1, 2024. The group is within the scope of these rules. Therefore, is required to calculate its GloBe effective tax rate 
for each jurisdiction in which it is present and is liable to pay a top-up tax for the difference between its Globe 
effective tax rate per jurisdiction and the 15% minimum rate. The group applies the IAS 12 exception regarding the 
recognition and disclosure of deferred tax assets and liabilities related to Pillar Two income taxes.  
 
 
P 
Employee benefits 
 
(1) 
Short-term obligations 
 
Liabilities for wages and salaries are recognized in respect of employees’ services up to the end of the reporting 
period and are measured at the amounts expected to be paid when the liabilities are settled. The liabilities are 
presented as current employee benefit obligations in the balance sheet. 
 
(2) 
Post-employment benefits 
 
The Company has defined benefit and defined contribution plans. A defined benefit plan is a pension plan that 
defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or 
more factors such as age, years of service and compensation.  
 
 

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
284 
 
The liability recognized in the statement of financial position in respect of defined benefit pension plans is the 
present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets, 
if any. The defined benefit obligation is calculated annually (at year end) by independent actuaries using the 
projected unit credit method. The present value of the defined benefit obligation is determined by discounting the 
estimated future cash flows using interest rates of high-quality corporate bonds that are denominated in the 
currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the 
related pension obligation.  
 
Remeasurement gains and losses arising from experience adjustments and changes in actuarial assumptions are 
charged or credited to equity in Other comprehensive income in the period in which they arise. Past-service costs 
are recognized immediately in the Income Statement. 
 
For defined benefit funded plans, net interest income / expense is calculated based on the surplus or deficit derived 
by the difference between the defined benefit obligations less fair value of plan assets.  
 
For defined contribution plans, the Company pays contributions to publicly or privately administered pension 
insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations 
once the contributions have been paid. The contributions are recognized as employee benefit expenses when they 
are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the 
future payments is available.  
 
Tenaris sponsors funded and unfunded defined benefit pension plans in certain subsidiaries. The most significant 
are:  
 
▪ 
An unfunded defined benefit employee retirement plan for certain senior officers. The plan is designed to 
provide certain benefits to those officers (additional to those contemplated under applicable labor laws) in case 
of termination of the employment relationship due to certain specified events, including retirement. This 
unfunded plan provides defined benefits based on years of service and final average salary. As of December 31, 
2024 the outstanding liability for this plan amounts to $59.4 million. 
 
▪ 
Employees’ service rescission indemnity. The cost of this obligation is charged to the Consolidated Income 
Statement over the expected service lives of employees. This provision is primarily related to the liability accrued 
for employees at Tenaris’s Italian subsidiary. As from January 1, 2007 as a consequence of a change in an Italian 
law, employees were entitled to make contributions to external funds, thus, Tenaris’s Italian subsidiary pays 
every year the required contribution to the funds with no further obligation. As a result, the plan changed from 
a defined benefit plan to a defined contribution plan effective from that date, but only limited to the 
contributions of 2007 onwards. As of December 31, 2024 the outstanding liability for this plan amounts to 
$10.1 million. 
 
▪ 
Funded retirement benefit plan held in the U.S. for the benefit of some employees hired prior a certain date, 
frozen for the purposes of credited service as well as determination of final average pay for the retirement 
benefit calculation. Plan assets consist primarily of investments in equities and money market funds. 
Additionally, an unfunded post-retirement health and life plan is in place that offers limited medical and life 
insurance benefits to the retirees, frozen to new participants. As of December 31, 2024 the outstanding liability 
for these plans amounts to $3.0 million. 
 
▪ 
Funded retirement benefit plans held in Canada for salary and hourly employees hired prior to a certain date 
based on years of service and, in the case of salaried employees, final average salary. Plan assets consist primarily 
of annuities purchased from an insurance company for the benefit of current and future retirees, as well as 
investments in debt instruments. Both plans were replaced for defined contribution plans. Effective June 2016 
the salary plan was frozen for the purposes of credited service as well as determination of final average pay. In 
2022, the plant at which all members of the hourly plan were employed was decommissioned and all members 
ceased to accrue benefits under the plan. As of December 31, 2024 the plans were overfunded and the net 
assets related to these plans amounted to $9.0 million. 
 
By their design, the defined benefit plans expose the Company to the typical risks faced by defined benefit plans 
such as investment performance, changes to discount rates used to value the obligations, rate of compensation 
increase (including inflation rates) and longevity of plan members . Pension and benefit risks are managed by regular 
monitoring of the plans, applicable regulations and other factors that may impact the Company’s expenses and 
cash flows.  
 

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
285 
 
The unfunded defined benefit plans are met as they fall due and are managed directly by the Company, which is 
entirely responsible for the plans. The funded defined benefit pension plans are governed and administered in 
accordance with applicable pension legislation in each jurisdiction. Each plan has an overseeing committee. The 
defined benefit plans are monitored on an ongoing basis to assess the funding and investment policies, financial 
status, and funding requirements. Significant changes to a plan or policy would be subject to approval by the board 
of directors of each subsidiary of the Company.  
 
(3) Other long-term benefits  
 
During 2007, Tenaris launched an employee retention and long-term incentive program (“the Program”) applicable 
to certain senior officers and employees of the Company, who will be granted a number of units throughout the 
duration of the Program. The value of each of these units is based on Tenaris’s shareholders’ equity (excluding non-
controlling interest). Until the end of 2017, the units were vested ratably over a period of four years and were 
mandatorily redeemed by the Company ten years after grant date, with the option of an early redemption at seven 
years after the grant date. Since 2018, the units are vested ratably over the same period and are mandatorily 
redeemed by the Company seven years after grant date.  
 
The beneficiaries of the Program are entitled to receive cash amounts based on: (i) the amount of dividend payments 
made by Tenaris to its shareholders and (ii) the number of units held by each beneficiary to the Program. The 
payment of the benefit is tied to the book value of the shares, and not to their market value. Tenaris valued this 
long-term incentive program as a long-term benefit plan as classified in IAS 19, “Employee Benefits”. 
 
As of December 31, 2024 and 2023, the outstanding liability corresponding to the Program amounts to $148.0 
million and $119.6 million, respectively. The total value of the units granted (vested and unvested) to date under 
the program, considering the number of units and the book value per share as of December 31, 2024 and 2023, is 
$175.0 million and $144.0 million, respectively. 
 
(4) Termination benefits 
 
Termination benefits are payable when employment is terminated by Tenaris before the normal retirement date, or 
when an employee accepts voluntary redundancy in exchange for these benefits. Tenaris recognizes termination 
benefits at the earlier of the following dates: (a) when it can no longer withdraw the offer of those benefits; and 
(b) when the costs for a restructuring that is within the scope of IAS 37 involves the payment of terminations 
benefits. In the case of an offer made to encourage voluntary redundancy, the termination benefits are measured 
based on the number of employees expected to accept the offer. 
 
(5) Other compensation obligations 
 
Employee entitlements to annual leave, long-service leave, sick leave and other bonuses and compensations 
obligations are accrued as earned. 
 
Compensation to employees in the event of dismissal is charged to income in the year in which it becomes payable. 
 
 
Q 
Provisions  
 
Tenaris is subject to various claims, lawsuits and other legal proceedings, including customer claims, in which a third 
party is seeking payment for alleged damages, reimbursement for losses or indemnity. Tenaris’s potential liability 
with respect to such claims, lawsuits and other legal proceedings cannot be estimated with certainty. Management 
periodically reviews the status of each significant matter and assesses potential financial exposure. If, as a result of 
past events, a potential loss from a claim or proceeding is considered probable and the amount can be reliably 
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 Tenaris’s litigation and settlement strategies. These estimates are primarily constructed 
with the assistance of legal counsel. As the scope of liabilities become better defined, there may be changes in the 
estimates of future costs which could have a material adverse effect on its results of operations, financial condition 
and cash flows.

286 
 
If Tenaris expects to be reimbursed for an accrued expense, as would be the case for an expense or loss covered 
under an insurance contract, and reimbursement is considered virtually certain, the expected reimbursement is 
recognized as a receivable.  
 
This note should be read in conjunction with note 27 to these Consolidated Financial Statements. 
 
 
R  
Trade and other payables  
 
Trade and other payables are recognized initially at fair value, generally the nominal invoice amount and 
subsequently measured at amortized cost. They are presented as current liabilities unless payment is not due within 
twelve months after the reporting period. Due to their short-term nature their carrying amounts are considered to 
be the same as their fair value.  
 
 
S 
Revenue recognition  
 
Revenue comprises the fair value of the consideration received or receivable for the sale of goods and rendering of 
services in the ordinary course of Tenaris’s activities. The revenue recognized by the Company is measured at the 
transaction price of the consideration received or receivable to which the Company is entitled to, reduced by 
estimated returns and other customer credits, such as discounts and volume rebates, based on the expected value 
to be realized and after eliminating sales within the group.  
 
Revenue is recognized at a point in time or over time from sales when control has been transferred and there is no 
unfulfilled performance obligation that could affect the acceptance of the product by the customer. The control is 
transferred upon delivery. Delivery occurs when the products have been shipped to the specific location, the risks 
of obsolescence and loss have been transferred and either the customer has accepted the product in accordance 
with the sales contract, the acceptance provisions have lapsed or the Company has objective evidence that all criteria 
for acceptance have been satisfied, including all performance obligations. These conditions are determined and 
analyzed on a contract by contract basis to ensure that all performance obligations are fulfilled. In particular, Tenaris 
verifies customer acceptance of the goods, the satisfaction of delivery terms and any other applicable condition. 
 
For bill and hold transactions revenue is recognized only to the extent that (a) the reason for the bill and hold 
arrangement must be substantive (for example, the customer has requested the arrangement); (b) the products 
have been specifically identified and are ready for delivery; (c) the Company does not have the ability to use the 
product or to direct it to another customer; (d) the usual payment terms apply. 
 
The Company’s contracts with customers do not provide any material variable consideration, other than discounts, 
rebates and right of return. Discounts and rebates are recognized based on the most likely value and rights of return 
are based on expected value considering past experience and contract conditions. 
  
Where the contracts include multiple performance obligations, the transaction price is allocated to each 
performance obligation based on the stand-alone selling prices. Where these are not directly observable, they are 
estimated based on the expected cost plus margin. 
 
There are no judgements applied by management that significantly affect the determination of timing of satisfaction 
of performance obligations, nor the transaction price and amounts allocated to different performance obligations.  
 
Tenaris provides services primarily related to goods sold, which represent a non-material portion of sales revenue 
and mainly include: 
 
Pipe management services: This comprises mainly preparation of the pipes ready to be run, delivery to the customer, 
storage services and rig return. 
 
Field services: Comprises field technical support and running assistance. 
 
 

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
287 
 
These services are rendered in connection to the sales of goods and are attached to contracts with customers for 
the sale of goods. A significant portion of service revenue is recognized in the same period as the goods sold. There 
are no distinct uncertainties in the revenues and cash flows of the goods sold and services rendered as they are 
included in the same contract, have the same counterparty and are subject to the same conditions. 
 
The following inputs and outputs methods are applied to recognize revenue considering the nature of service:  
 
Storage services: the Company provides storage services in owned or third-party warehouses, subject to a variable 
fee to be invoiced. This fee is determined based on the time that the customer maintains 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. 
▪ 
Net income from other sales: when control is transferred to the customer. 
 
 
T 
Cost of sales and other selling expenses 
 
Cost of sales and other selling expenses are recognized in the Consolidated Income Statement on the accrual basis 
of accounting. 
 
Commissions, freights and other selling expenses, including shipping and handling costs, are recorded in Selling, 
general and administrative expenses in the Consolidated Income Statement.

U 
Earnings per share 
 
Earnings per share are calculated by dividing the income attributable to the shareholders’ equity by the monthly 
weighted average number of common shares outstanding during the period. 
 
There are no dilutive potential ordinary shares. 
 
 
V 
Financial instruments  
 
Non-derivative financial instruments comprise investments in financial debt instruments and equity, time deposits, 
contract assets, trade and other receivables, cash and cash equivalents, borrowings and trade and other payables. 
 
The Company classifies its financial instruments according to the following measurement categories: 
 
▪ 
those to be measured subsequently at fair value (either through OCI or through profit or loss), and 
▪ 
those to be measured at amortised cost. 
 
The classification depends on the Company’s business model for managing the financial assets and contractual 
terms of the cash flows.  
 
Financial assets are recognized on their settlement date. Financial assets are derecognized when the rights to receive 
cash flows from the financial assets have expired or have been transferred and the Company has transferred 
substantially all the risks and rewards of ownership. 
 
At initial recognition, the Company measures a financial asset at its fair value plus, in the case of a financial asset 
not at fair value through profit or loss, transaction costs that are directly attributable to the acquisition of the 
financial asset. Transaction costs of financial assets carried at fair value through profit or loss are expenses in profit 
or loss.  
 
Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset 
and the cash flow characteristics of the asset. There are three measurement categories into which the Company 
classifies its debt instruments: 
 
Amortized Cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely 
payments of principal and interest. Interest income from these financial assets is included in finance income using 
the effective interest rate method. 
 
Exchange gains and losses and impairments related to the financial assets are immediately recognized in the 
Consolidated Income Statement. 
 
Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and 
for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest. 
Interest income from these financial assets is included in finance income using the effective interest rate method. 
Unrealized gains or losses are recorded as a fair value adjustment in the Consolidated Statement of Comprehensive 
Income and transferred to the Consolidated Income Statement when the financial asset is sold. 
 
Fair value through profit and loss: Assets that do not meet the criteria for amortized cost or FVOCI. Changes in fair 
value of financial instruments at FVPL are immediately recognized in the Consolidated Income Statement. 
 
Equity instruments are subsequently measured at fair value.  
 
Accounting for derivative financial instruments and hedging activities is included within the section III, Financial Risk 
Management.

III. FINANCIAL RISK MANAGEMENT  
 
The multinational nature of Tenaris’s operations and customer base exposes the Company to a variety of risks, 
mainly related to market risks (including the effects of changes in foreign currency exchange rates and interest 
rates), credit risk and capital market risk. In order to manage the volatility related to these exposures, management 
evaluates exposures on a consolidated basis, taking advantage of exposure netting. The Company or its subsidiaries 
may then enter into various derivative transactions in order to prevent potential adverse impacts on Tenaris’s 
financial performance. Such derivative transactions are executed in accordance with internal policies and hedging 
practices. 
 
 
A. Financial risk factors 
 
(i)  
Capital risk management 
 
Tenaris seeks to maintain a low debt to total equity ratio considering the industry and the markets where it operates. 
The year-end ratio of debt to total equity (where “debt” comprises financial borrowings and “total equity” is the 
sum of financial borrowings and equity) is 0.03 as of December 31, 2024 and 2023. The Company does not have 
to comply with regulatory capital adequacy requirements. 
 
 (ii) 
Foreign exchange risk  
 
Tenaris manufactures and sells its products in a number of countries throughout the world and consequently is 
exposed to foreign exchange rate risk. Since the Company’s functional currency is the U.S. dollar the purpose of 
Tenaris’s foreign currency hedging program is mainly to reduce the risk caused by changes in the exchange rates of 
other currencies against the U.S. dollar. 
 
Tenaris’s exposure to currency fluctuations is reviewed on a periodic and consolidated basis. A number of derivative 
transactions are performed in order to achieve an efficient coverage in the absence of operative or natural hedges. 
Almost all of these transactions are forward exchange rates contracts. See note 26 to these Consolidated Financial 
Statements. 
 
Tenaris does not enter into derivative financial instruments for trading or other speculative purposes, other than 
non-material investments in structured products. 
 
In the case of subsidiaries with functional currencies other than the U.S. dollar, the results of hedging activities, 
reported in accordance with IFRS, may not reflect entirely the management’s assessment of its foreign exchange 
risk hedging program. Intercompany balances between Tenaris’s subsidiaries may generate financial gains (losses) 
to the extent that functional currencies differ. 
 
The value of Tenaris’s financial assets and liabilities is subject to changes arising from the variation of foreign 
currency exchange rates. The following table provides a breakdown of Tenaris’s main financial assets and liabilities 
(including foreign exchange derivative contracts) which impact the Company’s profit and loss as of December 31, 
2024 and 2023.

▪ 
Euro / U.S. dollar 
 
As of December 31, 2024 and 2023 consisting primarily of Euro-denominated intercompany liabilities at certain 
subsidiaries whose functional currency is the U.S. dollar. A change of 1% in the EUR/USD exchange rate would 
have generated a pre-tax gain / loss of $1.8 million and $2.0 million as of December 31, 2024 and 2023, 
respectively, which would have been to a large extent offset by changes in currency translation adjustment 
included in Tenaris’s net equity position.

▪ 
Saudi Arabian Riyal / U. S. dollar 
 
As of December 31, 2024 and 2023 consisting primarily of Saudi Arabian Riyal-denominated financial and trade 
payables. The Saudi Arabian Riyal is tied to the U.S. dollar. 
 
▪ 
Argentine Peso / U.S. dollar 
 
As of December 31, 2024 and 2023 consisting primarily of Argentine Peso-denominated financial, trade, social 
and fiscal payables at certain Argentine subsidiaries whose functional currency is the U.S. dollar. A change of 
1% in the ARS/USD exchange rate would have generated a pre-tax gain / loss of $0.4 million and $1.3 million 
as of December 31, 2024 and 2023 respectively. 
 
▪ 
Brazilian Real / U.S. dollar 
 
As of December 31, 2024 and 2023 consisting primarily of Brazilian Real-denominated liabilities at certain 
Brazilian subsidiaries whose functional currency is the U.S. dollar. A change of 1% in the BRL/USD exchange rate 
would have generated a pre/-tax gain / loss of $0.4 million and $0.3 million as of December 31, 2024 and 2023 
respectively. 
 
Considering the balances held as of December 31, 2024 on financial assets and liabilities exposed to foreign 
exchange rate fluctuations, Tenaris estimates that the impact of a simultaneous 1% favorable / unfavorable 
movement in the levels of foreign currencies exchange rates relative to the U.S. dollar, would be a pre-tax gain / 
loss of $5.8 million (including a loss / gain of $1.5 million due to foreign exchange derivative contracts), which 
would be partially offset by changes to Tenaris’s net equity position of $1.4 million. For balances held as of 
December 31, 2023, a simultaneous 1% favorable / unfavorable movement in the foreign currencies exchange rates 
relative to the U.S. dollar, would have generated a pre-tax gain / loss of $6.7 million (including a loss / gain of $2.3 
million due to foreign exchange derivative contracts), which would have been partially offset by changes to Tenaris’s 
net equity position of $1.1 million. 
 
Tenaris based its foreign exchange sensitivity analysis on a 1% variance for information purposes only, enabling the 
analysis to any particular variance. 
 
(iii) 
Interest rate risk 
 
Tenaris is subject to interest rate risk on its investment portfolio and its debt. The Company uses a mix of variable 
and fixed rate debt in combination with its investment portfolio strategy. The Company may choose to enter into 
foreign exchange derivative contracts and / or interest rate swaps to mitigate the exposure to changes in the interest 
rates.  
 
The following table summarizes the proportions of variable-rate and fixed-rate debt as of each year end.

higher, then the additional pre-tax loss would have been $5.5 million in 2024 and $6.4 million in 2023.  
 
Tenaris based its interest rate sensitivity analysis on a 100 basis points variance for information purposes only,

(iv) 
Credit risk 
 
Credit risk arises from cash and cash equivalents, deposits with banks and financial institutions, as well as credit 
exposures from customers, including outstanding receivables and committed transactions. The Company also 
actively monitors the creditworthiness of its treasury, derivative and insurance counterparties in order to minimize 
its credit risk. 
 
There is no concentration of credit risk and no single customer comprised more than 10% of Tenaris’s net sales in 
2024, 2023 and 2022.  
 
Tenaris maintains a strong, longstanding relationship with Petróleos Mexicanos (“Pemex”), one of the world’s 
largest crude oil and condensates producers and one of its largest customers. Over the past several months, Pemex 
has delayed payments beyond the agreed-upon due dates, resulting in Tenaris having a significant credit exposure 
to Pemex, which represented approximately 17% of the Company’s overall credit exposure as of December 31, 
2024, and approximately 20% of the Company’s overall credit exposure as of December 31, 2023. In December 
2024, Pemex issued senior guaranteed floating rate notes due in 2025 that a financial institution purchased on the 
issue date, with Pemex agreeing to use a portion of the proceeds from the sale of such notes to pay off outstanding 
debt with one of the Company’s Mexican subsidiaries for approximately $200 million. The fee related to this 
transaction, amounting to approximately to $16 million, was borne by the Company and included in Other financial 
results. 
 
Tenaris’s credit policies related to sales of products and services are designed to identify customers with acceptable 
credit history and to allow Tenaris to require the use of credit insurance, letters of credit and other instruments 
designed to minimize credit risks whenever deemed necessary. Tenaris maintains allowances for impairment for 
potential credit losses. See section II.K. 
 
As of December 31, 2024, trade receivables amounted to $1,907.5 million. Trade receivables had guarantees under 
credit insurance of $208.5 million, letter of credit and other bank guarantees of $79.8 million. Overdue trade 
receivables amounted to $395.5 million, overdue guaranteed trade receivables amounted to $33.6 million; and the 
allowance for doubtful accounts amounted to $48.1 million.  
 
As of December 31, 2023, trade receivables amounted to $2,480.9 million. Trade receivables had guarantees under 
credit insurance of $212.7 million, letter of credit and other bank guarantees of $48.4 million. Overdue trade 
receivables amounted to $679.6 million, overdue guaranteed trade receivables amounted to $24.4 million; and the 
allowance for doubtful accounts amounted to $49.0 million. 
 
Management believes that both the allowance for doubtful accounts and the existing guarantees are sufficient to 
cover doubtful trade receivables. 
 
(v)  
Counterparty risk 
 
Tenaris has investment guidelines with specific parameters to limit issuer risk on marketable securities. 
Counterparties for derivatives and cash transactions are limited to high credit quality financial institutions, normally 
investment grade. 
 
Approximately 91.4% of Tenaris’s liquid financial assets corresponded to Investment Grade-rated instruments as of 
December 31, 2024, in comparison with approximately 90.8% as of December 31, 2023. 
 
(vi) 
Liquidity risk 
  
Tenaris’s financing strategy aims to maintain adequate financial resources and access to additional liquidity. During 
2024, Tenaris has counted on cash flows from operations as well as additional bank financing to fund its 
transactions. 
 
Management maintains sufficient cash and marketable securities to finance normal operations and believes that 
Tenaris also has appropriate access to market for short-term working capital needs. 
 
Liquid financial assets as a whole (comprising cash and cash equivalents and other investments) were 20% and 
19% of total assets at the end of 2024 and 2023, respectively.  
 

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
292 
 
 
Tenaris has a conservative approach to the management of its liquidity, which consists of i) cash and cash 
equivalents (cash in banks, liquidity funds and investments with a maturity of less than three months at the date of 
purchase), and ii) other investments (fixed income securities, time deposits, and fund investments). 
 
Tenaris holds primarily investments in money market funds and variable or fixed-rate securities from investment 
grade issuers.  
 
Tenaris holds its investments primarily in U.S. dollars. As of December 31, 2024 and 2023, U.S. dollar denominated 
liquid assets plus investments denominated in other currencies hedged to the U.S. dollar represented approximately 
93% and 94% of total liquid financial assets, respectively. 
 
(vii) 
Commodity price risk 
 
In the ordinary course of its operations, Tenaris purchases commodities and raw materials that are subject to price 
volatility caused by supply conditions, political and economic variables and other factors. As a consequence, Tenaris 
is exposed to risk resulting from fluctuations in the prices of these commodities and raw materials. Tenaris fixes the 
prices of such raw materials and commodities for short-term periods, typically not in excess of one year, and in 
general hedging for these risks is performed on a limited basis. 
 
 
 
B. Category of financial instruments and classification within the fair value hierarchy 
 
As mentioned in note II.V, the Company classifies its financial instruments in the following measurement categories: 
amortized cost, fair value through other comprehensive income and fair value through profit and loss. For financial 
instruments that are measured in the statement of financial position at fair value, IFRS 13, “Fair value measurement” 
requires a disclosure of fair value measurements by level according to the following fair value measurement 
hierarchy: 
 
Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities. 
 
Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either 
directly (that is, as prices) or indirectly (that is, derived from prices). 
 
Level 3: Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs).

(*) Includes liability related to share buyback program. See note 35 to these Consolidated Financial Statements. 
Certain non-financial assets and liabilities were included in the above table to allow reconciliation with the Statements of Financial Position. 
Due to their short time nature, the carrying amounts of trade receivables, trade payables, other financial receivables (including contract assets), 
other financial liabilities and other investments are considered to be similar to their fair values. 
 
There were no transfers between levels during the year. 
 
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.

295 
 
If one or more of the significant inputs are not based on observable market data, the instruments are included in 
Level 3. The Company values its assets and liabilities in this level using management assumptions which reflect the 
Company’s best estimate on how market participants would price the asset or liability at measurement date. As of 
December 31, 2024 and 2023, main balances in this level included a liability related to the shares to be settled 
under the share buyback program. Unobservable inputs related to this balance include assumptions regarding 
average purchase prices of previous periods, and management's past experience related to the conclusion of the 
share buy-back program itself. A reasonable change in the inputs used would not affect the fair value of the liability 
materially. For more information see note 35.

C. Fair value estimation  
 
Financial assets or liabilities classified at fair value through profit or loss are measured under the framework 
established by the IASB accounting guidance for fair value measurements and disclosures. 
 
The fair values of quoted investments are generally based on current bid prices. If the market for a financial asset is 
not active or no market is available, fair values are established using standard valuation techniques.  
 
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. 
 
Borrowings are classified under other financial liabilities and measured at their amortized cost. Tenaris estimates 
that the fair value (level 2) of its main borrowings is approximately 98.3% and 99.8% of its carrying amount 
(including interests accrued) in 2024 and 2023 respectively. Fair values were calculated using standard valuation 
techniques for floating rate instruments and comparable market rates for discounting cash flows. 
 
The carrying amount of investments recognized at amortized cost approximates its fair value. 
 
 
D. Accounting for derivative financial instruments and hedging activities 
 
Tenaris uses derivative financial instruments principally to manage its exposure to fluctuations in exchange rates 
and prices of raw materials. Derivative financial instruments are classified as current or non-current assets or liabilities 
based on their maturity dates. Derivative financial instruments are initially recognized in the statement of financial 
position at fair value. Tenaris uses market prices or specific tools for calculation of each instrument’s fair value, these 
tools are tested for consistency on a monthly basis. Market rates are used for all pricing operations. These include 
exchange rates, deposit rates and other discount rates matching the nature of each underlying risk. Gains or losses 
arising from changes in fair value of derivatives are recognized in Financial Results in the Consolidated Income 
Statement, except for derivatives that are designated and qualify for hedge accounting.

296 
 
Tenaris designates certain derivatives as hedges of particular risks associated with recognized assets or liabilities or 
highly probable forecast transactions. These transactions are classified as cash flow hedges. The effective portion of 
the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in equity. Amounts 
accumulated in equity are then recognized in the income statement in the same period as the offsetting losses and 
gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the 
income statement. The fair value of Tenaris’s derivative financial instruments (assets or liabilities) continues to be 
reflected in the statement of financial position. 
 
For transactions designated and qualifying for hedge accounting, Tenaris documents at the inception of the 
transaction the relationship between hedging instruments and hedged items, as well as its risk management 
objectives and strategy for undertaking various hedge transactions. Tenaris also documents its assessment on an 
ongoing basis, of whether the hedging instruments are highly effective in offsetting changes in the fair value or 
cash flow of hedged items. At December 31, 2024 and 2023, the effective portion of designated cash flow hedges 
which is included in Other Reserves in equity amounted to $0.6 million debit and $8.1 million credit respectively. 
 
The fair values of various derivative instruments used for hedging purposes and the movements of the hedging 
reserve included within Other Reserves in equity are disclosed in note 26 to these Consolidated Financial Statements.

There are no material differences between IFRS and management view in total revenues. 
 
The differences between operating income under IFRS and the management views are mainly related to the cost of 
goods sold, reflecting the effect of raw materials prices increases on the valuation of the replacement cost 
considered for management view compared to IFRS cost calculated at historical cost on a FIFO basis, and other 
minor timing differences.

The main difference in Other operating income (expenses), net, for the year ended December 31, 2022, is 
attributable to the effect of the reclassification of the currency translation adjustment reserve related to NKK Tubes’ 
definitive cease of operations, not impacting the management view. 
 
The main differences in net income under the IFRS and management views arise from the impact of functional 
currencies on financial result, deferred income taxes as well as the equity in earnings of non-consolidated 
companies. 
 
Following the integration of coating activities into its Tubes segment, the Company represented year-to-date 
segment information amounts accordingly.

Impairment charge 
 
Tenaris conducts regular assessments of the carrying values of its assets. The recoverable value is based on the value 
in use. The main key assumptions used in estimating the value in use are discount rate, growth rate and competitive, 
economic and regulatory factors applied to determine cash flow projections, such as oil and gas prices, average 
number of active oil and gas drilling rigs (rig count) and raw material costs. 
 
In December 2024, even though the Company did not identify any impairment indicators, it conducted impairment 
tests for the CGUs with goodwill in their carrying amounts and no impairment charges were recorded. The main 
discount rates used were in a range between 13.4% and 18.2% and a nominal growth rate (which includes mainly 
the inflation impact on prices and costs) of 2% was considered. For the CGUs carrying goodwill, a reasonably 
possible change in key assumptions would not cause the carrying amount to exceed its recoverable amount.  
 
In December 2023, considering that the recoverable amount of the CGUs obtained in prior years' tests and that the 
assets and liabilities making up those units had not changed significantly, nor the key assumptions mentioned 
above, the Company concluded that impairment tests for previous years were still valid. In addition, the Company 
had considered the impact of updating the main discount rates, applying rates in a range between 12.5% and 
21.4% for the CGUs under analysis. In 2023, a nominal growth rate (which included mainly the inflation impact on 
prices and costs) of 2% was considered. Based on the facts mentioned above, the Company did not recognize any 
impairment charges for the year 2023. 
 
In December 2022, in the presence of impairment indicators, the Company conducted impairment tests and 
reviewed the values of certain idle assets in its subsidiaries. The aforementioned analysis resulted in impairment 
charges of $76.7 million, allocated in $63.1 million to the Tubes segment and $13.6 million to the Other segment. 
The main discount rates used were in a range between 13.4% and 20.2%. In 2022, a nominal growth rate (which 
included mainly the inflation impact on prices and costs) of 2% was considered.

The group is within the scope of the OECD Pillar Two model rules. Pillar Two legislation was adopted in Luxembourg, 
the jurisdiction in which the Company is incorporated, and came into effect as from January 1, 2024. The group 
applies the exception regarding the recognition and disclosure of deferred tax assets and liabilities related to Pillar 
Two income taxes, as provided for in the amendments to IAS 12 issued in May 2023.  
 
For the year 2024, Tenaris recognized an estimated current tax expense related to Pillar Two, amounting to $81.4 
million. 
 
The tax charge differs from the theoretical amount that would arise by applying the nominal tax rate valid in each 
jurisdiction to the group's pre-tax income in that jurisdiction as follows:

Effect of currency translation on tax base: Tenaris applies the liability method to recognize deferred income tax on 
temporary differences between the tax bases of assets / liabilities and their carrying amounts in the financial 
statements. By application of this method, Tenaris recognizes gains and losses on deferred income tax due to the 
effect of the change in the value on the tax bases in subsidiaries (mainly Argentina and Mexico), which have a 
functional currency different than their local currency. These gains and losses are required by IFRS even though the 
revalued / devalued tax bases of the relevant assets will not result in any deduction / obligation for tax purposes in 
future periods. 
 
Changes in the tax rates: For the year 2024, the effect relates to the impact of the reduction in Luxembourg's 
corporate income tax rate that made the blended tax rate for a company registered in Luxembourg Ville decrease 
from 24.94% to 23.87%. The new blended tax rate is applicable for fiscal years beginning on or after January 1, 
2025, but its effect over temporary differences is recognized in 2024. 
 
Tax revaluation, withholding tax and others: Includes a positive effect from inflationary tax adjustments in Argentina 
and Mexico of $368.2 million, $349.0 million and $250.4 million for the years 2024, 2023 and 2022, respectively. 
It also includes a charge of $20.0 million, $164.3 million and $21.0 million for the years 2024, 2023 and 2022, 
respectively related to withholding taxes for intra-group international operations. The years 2024 and 2023 include 
a positive effect of $186.0 million and $550.3 million, respectively, arising from the recognition of previous year’s 
tax losses carryforward deferred tax assets in the Luxembourg subsidiary. For the year 2024, the consumption of 
such deferred tax assets for $86.9 million is included in the line “Tax calculated at the tax rate of each country”. 
For more information see note 22. The year 2024 includes a charge of $81.4 million related to Pillar Two.

pipes business. 
 
At December 31, 2024, the closing price of Ternium’s ADSs as quoted on the New York Stock Exchange was $29.08 
per ADS, giving Tenaris’s ownership stake a market value of approximately $668.0 million. At December 31, 2024,

previously held interest, the price paid for the acquisition of the additional Usiminas shares and the fair value 
measurement of the Usiminas shares (conducted at the T/T Group level) the Company recorded a net loss of $25.5 
million included in Equity in earnings of non-consolidated companies in the Consolidated Income Statement.

c) Techgen 
 
Techgen is a Mexican company that operates a natural gas-fired combined cycle electric power plant in the Pesquería 
area of the State of Nuevo León, Mexico, with a power capacity of 900 megawatts. As of December 31, 2024, 
Tenaris held 22% of Techgen’s share capital, and its affiliates, Ternium and Tecpetrol (both controlled by San 
Faustin), beneficially owned 48% and 30% respectively. As of December 31, 2024, the carrying value of Tenaris’s 
ownership stake in Techgen was approximately $59.8 million. 
 
Techgen entered into certain transportation capacity agreements and an agreement for the purchase of clean 
energy certificates. As of December 31, 2024, Tenaris’s exposure under these agreements amounted to $36.3 
million and $16.6 million respectively. 
 
Techgen’s sponsors granted certain subordinated loans to Techgen. As of December 31, 2024, the aggregate 
outstanding principal amount under these subordinated loans was $306.5 million, of which $67.4 million 
correspond to Tenaris’s contribution. 
 
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 guarantees previously issued by Techgen’s 
shareholders to secure the replaced facility. 
 
The existing syndicated loan agreement is “non-recourse” on the sponsors. Techgen’s obligations thereunder are 
guaranteed by a Mexican security trust (covering shares, assets, accounts and contract rights), account pledges and 
certain direct agreements –customary for these type of transactions–. The commercial terms and conditions 
governing the purchase by the Company’s Mexican subsidiary, Tamsa, of 22% of the energy generated by Techgen 
remain substantially 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 applied for stand-by letters of credit covering 22% of the debt service coverage ratio, which as of 
December 31, 2024, amounted to $10.9 million.

Deferred tax assets related to tax losses of Tenaris subsidiaries are recognized to the extent it is probable that future 
taxable profits will be available, against which such losses can be utilized. The utilization of such tax losses may also 
be restricted by the nature of the profit, expiration dates and / or potential limitations on their yearly consumption. 
In determining the amount of deferred taxes to be recognized, Tenaris considered existing evidence, both positive 
and negative, including the historical taxable profits and the projections of future taxable profits prepared by 
management to assess the probability that the deferred tax assets will be realized. Management applies significant 
judgment in assessing the likelihood that future taxable profits will be available. 
 
Deferred tax assets related to tax losses as of the end of 2024 and 2023 include $623.8 million and $550.3 million 
respectively, recognized in its Luxembourg subsidiary mainly due to impairment charges over certain undertakings 
in the past years. Under the Luxembourg tax law, tax losses generated before 2017 can be carried forward 
indefinitely and are not subject to any yearly consumption limitation. Losses incurred as from 2017 may be carried 
forward for a maximum of 17 years.  
 
Tenaris has concluded as of end 2024 and 2023 that it is probable that sufficient future taxable profits will be 
generated by business carried out by its Luxembourg subsidiary which has expanded its activities including sales, 
distribution, logistics and marketing of steel products and other related services, against which the above-mentioned 
tax losses could be utilized prior to their expiration.  
 
Deferred tax assets related to tax losses as of the end of 2024 and 2023 also include $79.4 million and $77.9 million 
respectively, from U.S. subsidiaries mainly related to the acquisition of IPSCO in 2020. Tenaris has concluded that 
these deferred tax assets will be recoverable based on the business plans and budgets. 
 
Approximately 97% of the recognized tax losses have an expiration date in more than 5 years or do not expire. 
 
As of December 31, 2024, the unrecognized deferred tax assets originating in tax losses or tax credits amounted to 
$2,683.5 million.  
 
Approximately 98% of the unrecognized deferred tax assets have an expiration date in more than 5 years or do not 
expire. 
 
The estimated recovery analysis of deferred tax assets and settlement of deferred tax liabilities, which takes into 
consideration management assumptions and estimates, is as follows: 
  
Year ended December 31, 
 
2024 
2023 
Deferred tax assets to be recovered after 12 months 
755,743 
655,415 
Deferred tax liabilities to be settled after 12 months 
696,693 
689,976 
 
 
Deferred income tax assets and liabilities are offset when (1) there is a legally enforceable right to set-off current 
tax assets against current tax liabilities and (2) when the deferred income taxes relate to the same fiscal authority 
on either the same taxable entity or different taxable entities where there is an intention to settle the balances on 
a net basis. The following amounts, determined after appropriate set-off, are shown in the Consolidated Statement 
of Financial Position:

The actuarial assumptions for the most relevant plans were as follows: 
 
Year ended December 31,

2023 
Discount rate 
3% - 8% 
3% - 7% 
Rate of compensation increase 
2% - 6% 
2% - 5% 
 
 
As of December 31, 2024, an increase / (decrease) of 1% in the discount rate assumption of the main plans would 
have generated a (decrease) / increase on the defined benefit obligation of $6.6 million and $5.7 million respectively, 
and an increase / (decrease) of 1% in the rate of compensation assumption of the main plans would have generated 
an increase / (decrease) impact on the defined benefit obligation of $4.3 million and $4.8 million respectively. The 
above sensitivity analyses are based on a change in discount rate and rate of compensation while holding all other 
assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be 
correlated.

(*) For the years 2024 and 2023, mainly include annuities purchased from an insurance company for the benefit of current and future retirees.  
 
There are no unusual, entity-specific, or plan-specific risks in terms of the plan assets of funded pension plans. 
 
The actuarial assumptions for the most relevant plans were as follows: 
 
Year ended December 31, 
2024 
2023 
Discount rate 
5% - 6% 
5% - 5% 
Rate of compensation increase 
3% - 3% 
0% - 3% 
 
The expected return on plan assets is determined by considering the expected returns available on the assets 
underlying the current investment policy. Expected return on plan assets is determined based on long-term, 
prospective rates of return as of the end of the reporting period.  
 
As of December 31, 2024, an increase / (decrease) of 1% in the discount rate assumption of the main plans would 
have generated a (decrease) / increase on the defined benefit obligation of $8.8 million and $7.4 million respectively, 
and an increase / (decrease) of 1% in the compensation rate assumption of the main plans would have generated 
an increase / (decrease) on the defined benefit obligation of $0.6 million and $0.7 million respectively. The above 
sensitivity analyses are based on a change in discount rate and rate of compensation while holding all other 
assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be 
correlated. 
 
The expected employer contributions for the year 2025 are not material.  
 
The methods and types of assumptions used in preparing the sensitivity analyses did not change compared to the 
previous period.

27   Contingencies, commitments and restrictions on the distribution of profits  
 
(i) 
Contingencies 
 
Tenaris is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, 
employee, tax and environmental-related 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, the Company is unable to make a reliable estimate of the expected financial effect that will result from 
ultimate resolution of the proceeding. In those situations, the Company 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, 
the Company was able to make a reliable estimate of the expected loss or range of probable loss and, depending 
on the likelihood of occurrence, in some of such cases has accrued a provision for such loss but believes that 
publication of this information on a case-by-case basis would seriously prejudice the 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 Financial 
Statements are adequate based upon currently available information. However, if management’s estimates prove 
incorrect, current reserves could be inadequate and the Company could incur a charge to earnings which could 
have a material adverse effect on its 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 Financial Statements. In addition, the Company is subject to other legal proceedings, none of 
which is believed to be material. 
 
▪ 
CSN claims relating to the January 2012 acquisition of Usiminas 
 
The Company is party to a longstanding lawsuit filed in Brazil by Companhia Siderúrgica Nacional (“CSN”), and 
various entities affiliated with CSN against the Company’s Brazilian subsidiary Confab and three subsidiaries of 
Ternium, all of which compose the T/T Group under the Usiminas shareholders agreement. The entities named in 
the CSN lawsuit had acquired participations in Usiminas 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 sought 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. Confab’s share in the offer would be 17.9%. 
  
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 August 18, 2017, CSN filed an appeal to the 
Superior Court of Justice (“SCJ”) seeking the review and reversal of the decision issued by the Court of Appeals. 
On September 10, 2019, the SCJ declared CSN’s appeal admissible. On March 7, 2023, the SCJ, by majority vote, 
rejected CSN’s appeal.

CSN made several submissions in connection with the SCJ’s March 7, 2023 decision, including a motion for 
clarification that challenged the merits of the SCJ decision. Decisions at the SCJ are adopted by majority vote. At an 
October 17, 2023 session, two justices of the SCJ voted in favor of remanding the case to the first instance for it to 
be retried following production and assessment of the new evidence, and two justices of the SCJ voted, without 
requiring any further evidence, in favor of granting CSN’s motion for clarification and reversing the March 7, 2023 
decision that rejected CSN’s appeal; because the fifth member of SCJ excused himself from voting, a justice from 
another panel at the SCJ was summoned to produce the tie-breaking vote. On June 18, 2024, the SCJ completed 
its voting on CSN’s motion for clarification and reversed, by majority vote, its March 7, 2023 decision, and resolved 
that Confab and the three subsidiaries of Ternium should pay CSN an indemnification in connection with the 
acquisition by the T/T Group of a participation in Usiminas in January 2012, with CSN being allowed to retain 
ownership of the Usiminas ordinary shares it currently owns.  
 
On August 1, 2024, Confab and the other T/T Group entities filed a motion for clarification against the SCJ decision 
and, subsequently, CSN filed its reply. On December 6, 2024, the SCJ rejected this motion for clarification, 
confirming the obligation of Confab and the other T/T Group entities to pay indemnification in connection with the 
2012 acquisition of the participations in Usiminas. Notwithstanding the foregoing, the SCJ unanimously resolved to 
modify the applicable monetary adjustment mechanism and to cap the applicable attorney’s fees, thereby lowering 
the aggregate amount that would be payable if CSN ultimately prevails in this claim. Based on such SCJ decision, 
assuming monetary adjustment thorough December 31, 2024, and attorney’s fees in the amount of BRL5 million, 
the revised aggregate amount potentially payable by Confab if CSN finally prevails on its claims, would be of 
approximately BRL553.4 million (approximately $89.4 million at the BRL/$ rate as of such date). 
 
The Company continues to believe that all of CSN's claims and allegations are unsupported and without merit, as 
confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator in 
February 2012 and December 2016, the first and second instance court decisions and the March 7, 2023 SCJ 
decision referred to above, and that in connection with the Usiminas acquisition the T/T Group was not required 
either to launch a tender offer or to pay indemnification to CSN. Accordingly, on February 10, 2025, Confab and 
the other T/T Group entities filed an extraordinary appeal against the SCJ decisions that ordered an indemnification 
payment, seeking their review and reversal by the Supreme Federal Tribunal. The Company, however, cannot predict 
the ultimate resolution of the matter. 
 
▪ 
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, the court subsequently homologated the above-mentioned settlement and, 
accordingly, the claim was finalized.

▪ 
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 BRL110.5 million (approximately $17.8 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 
BRL94.8 million (approximately $15.3 million) of damages arising therefrom. Confab has additional defence 
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. In June 2022, 
the court resolved that it lacked jurisdiction to decide on the appeal, which was re-allocated to another 
court. On August 26, 2024, the court issued a decision rejecting certain procedural objections and ordering 
that new expert evidence be produced. As a result, the trial was redirected to the first instance court for 
new technical evidence to be produced by a new expert. On September 9, 2024, Veracel filed a motion for 
clarification, which was responded by Confab on October 23, 2024, and remains pending decision. At this 
stage, the Company cannot predict the outcome of the claim or the amount or range of loss in case of an 
unfavourable outcome.  
 
▪ Petrobras-related proceedings and claims 
 
Upon learning that Brazilian, Italian and Swiss authorities were investigating whether certain payments were made 
prior to 2014 from accounts of entities presumably associated with affiliates of the Company to accounts allegedly 
linked to individuals related to Petróleo Brasileiro S.A. (“Petrobras”) and whether any such payments were intended 
to benefit the Company’s Brazilian subsidiary Confab, the Audit Committee of the Company's Board of Directors 
engaged external counsel in connection with the Company’s review of these matters. In addition, the Company 
voluntarily notified the U.S. Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice 
(“DOJ”) in October 2016. The Company conducted, with the assistance of external counsel, an internal investigation 
and found no evidence corroborating any involvement by the Company or its directors, officers or employees in 
respect of improper payments. An internal investigation commissioned by Petrobras also found no evidence that 
Confab obtained any unfair commercial benefit or advantage from Petrobras in return for payments, including 
improperly obtained contracts. On June 2, 2022, the Company resolved the investigation by the SEC, and the DOJ 
informed that it had closed its parallel inquiry without taking action. Under the settlement with the SEC, the 
Company neither admits nor denies the SEC’s findings and on June 24, 2022, paid $53.1 million in disgorgement 
and prejudgment interest and $25 million for a civil penalty to conclude the matter. 
 
In July 2019, the Company learned that the public prosecutors’ office of Milan, Italy, had completed a preliminary 
investigation into the same alleged payments and had included in the investigation, among other persons, the 
Company’s Chairman and chief executive officer, two other board members, Gianfelice Rocca and Roberto Bonatti, 
and the Company’s controlling shareholder, San Faustin. The Company was not a party to the proceedings. On 
March 22, 2022, upon completion of the evidentiary phase of the trial, the acting prosecutor requested the first-
instance court in Milan in charge of the case to impose sanctions on our Chairman and chief executive officer, on 
the other two board members, and on San Faustin. On May 26, 2022, the first-instance court dismissed the case 
brought by the public prosecutor against the defendants for lack of jurisdiction and stated that the criminal 
proceeding should not have been initiated. On February 22, 2024, the court of appeals referred the case to the 
court of cassation, which, on May 23, 2024, confirmed the decision of the first-instance court and closed the case. 
 
In June 2020, the Brazilian public prosecutors’ office requested the indictment of several individuals, including three 
executives or former executives of Confab and a former agent of Confab, charging them with the alleged crimes 
of corruption in relation to contracts executed between 2007 and 2010, and money laundering in relation to 
payments between 2009 and 2013. On December 11, 2024, the Confab executives were acquitted. The acquittal 
has already been appealed, so the criminal proceedings continue to be underway. Neither the Company nor Confab 
is a party to these criminal proceedings. 
 
In addition, Petrobras and the Brazilian public prosecutors filed civil claims for alleged damages arising from the 
same events against, among others, Confab and the Confab executives named in the criminal proceedings referred 
to above. Confab became aware of these civil claims in September 2022. As of December 31, 2024, the aggregate 
amount of these claims was estimated at BRL193.2 million (or approximately $31.2 million). The plaintiffs also seek 
that Confab be prohibited from contracting with, or receiving benefits or exemptions from, the Brazilian state for 
an unspecified term. Confab believes these claims do not address either the defence arguments or the evidence 
available to the plaintiffs in Brazil and presented in other jurisdictions and is contesting them. At this stage, the 
Company cannot predict the outcome of these civil proceedings.

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 the same purported irregularities. Confab received notice of 
these proceedings in February 2025, and believes that the General Controllers’ Office’s allegations do not address 
either the defence arguments or the evidence available to the plaintiffs in Brazil and presented in other jurisdictions. 
Although the Company is defending itself, it 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, 2023, the judge granted summary judgment in favor of 
Global Tubing, concluding that the patents at issue are unenforceable due to inequitable conduct during the patent 
prosecution process. TCT appealed this judgment, and Global Tubing appealed a previous ruling of the judge. Global 
Tubing also filed a brief seeking to recover attorneys’ fees, without specifying the amount of those fees. Although 
it is not possible to predict the final outcome of this matter, the Company believes that any potential losses arising 
from this case will not be material. 
 
▪ 
U.S. Antidumping Duty Investigations 
 
On October 27, 2021, the U.S. Department of Commerce (“DOC”) initiated antidumping duty investigations of oil 
country tubular goods (“OCTG”) from Argentina, Mexico, and Russia. After the DOC issued affirmative preliminary 
and final antidumping determinations with respect to imports from Argentina, Mexico and Russia on October 27, 
2022, the International Trade Commission (“ITC”) determined that the imports under investigation caused injury to 
the U.S. OCTG industry. Tenaris and other parties have appealed the agency determinations from the investigation 
to the Court of International Trade, and, with respect to certain claims, to the Court of Appeals for the Federal 
Circuit. In addition, in response to a request from the Government of Argentina, the World Trade Organization 
(“WTO”) established a panel of experts to consider whether the DOC’s antidumping order applicable to Argentina 
is consistent with the international obligations of the United States. As a result of the investigation, and unless 
overturned on appeal, Tenaris is required to pay antidumping duty deposits (at a rate of 78.30% for imports from 
Argentina and 44.93% for imports from Mexico) until such time the imports are reviewed by the DOC to determine 
whether final duties are necessary for the specific period under review. Tenaris has been paying such deposits since 
May 11, 2022, reflecting the amount of such deposits in its costs. The deposit rates may be reset periodically based 
on the results of the review process. It is possible that, through the periodic review process, the deposits may be 
either returned to Tenaris in whole or in part, or may be increased.

(ii) 
Commitments and guarantees 
 
Set forth is a description of the Tenaris’s main outstanding commitments: 
 
▪ Certain subsidiaries of the Company entered into a long-term contract with Praxair S.A. for the service of oxygen 
and nitrogen supply. As of December 31, 2024, the aggregate amount to take or pay the committed volumes for 
an original 14-year term totaled approximately $28.1 million. 
 
▪ A Mexican subsidiary of the Company entered into a 25-year contract (effective as of December 1, 2016, through 
December 1, 2041) with Techgen for the supply of 197 MW (which represents 22% of Techgen’s capacity). 
Monthly payments are determined on the basis of capacity charges, operation costs, back-up power charges, and 
transmission charges. As of the seventh contract year (as long as Techgen’s existing or replacing bank facility has 
been repaid in full), the Company’s subsidiary has the right to suspend or early terminate the contract if the rate 
payable under the agreement is higher than the rate charged by the Mexican Comisión Federal de Electricidad 
(“CFE”) or its successors. The Company’s subsidiary may instruct Techgen to sell to any affiliate, to CFE, or to any 
other third party all or any part of unused contracted energy under the agreement and the Company’s subsidiary 
will benefit from the proceeds of such sale. 
 
▪ A U.S. subsidiary of the Company is a party to a contract with Nucor Steel Memphis Inc. under which it is 
committed to purchase on a monthly basis a specified minimum volume of steel bars, at prices subject to quarterly 
adjustments. The contract became effective in April 2021, with an original duration of 3 years. In September 2023, 
the parties agreed to extend its term until December 31, 2024 and in October 2024, agreed a renovation until 
December 31,2025. As of December 31, 2024, the estimated aggregate contract amount calculated at current 
prices, was approximately $57.7 million. The contract gives the subsidiary of the Company the right to temporarily 
reduce the quantities to be purchased thereunder to 75% of the agreed-upon minimum volume in cases of 
material adverse changes in prevailing economic or market conditions. 
 
▪ In connection with the closing of the acquisition of IPSCO, a U.S. subsidiary of the Company entered into a 6-year 
master distribution agreement (the “MDA”) with PAO TMK (“TMK”) whereby, since January 2, 2020, Tenaris 
became the exclusive distributor of TMK’s OCTG and line pipe products in United States and Canada. At the end 
of the MDA’s 6-year term, TMK would have the option to extend the duration of its term for an additional 12-
month period. Under the MDA, the Company is required to purchase specified minimum volumes of TMK-
manufactured OCTG and line pipe products, based on the aggregate market demand for the relevant product 
category in the United States in the relevant year. In February 2022, however, the Company and TMK agreed that 
there would be no minimum yearly purchase requirement for the OCTG product category for 2022, and there 
would be no minimum yearly purchase requirement for TMK line pipe products under the MDA neither for 2022, 
nor for any subsequent contract year until expiration of the MDA’s term. In addition, no purchases of TMK 
products were made during 2023 or 2024. 
 
▪ Certain subsidiaries of the Company entered into a long-term contract with the supplier JFE Steel Corporation for 
the purchase of tubular material, including 13 chrome alloy products. Such contract foresees a penalty for a 
maximum amount of $25.1 million in case of early termination. The contract is valid until June 30, 2029. 
 
▪ Certain subsidiaries of the Company entered into short-term agreements with Vestas Group for the supply of 
materials and services related to the construction of a wind farm in Argentina. As of December 31, 2024, the 
amount related to these commitments was $90.1 million. 
 
▪ An Argentine subsidiary of the Company entered into short-term agreements with COARCO S.A. for execution 
of civil and electrical works, including auxiliary services, related with the construction of a wind farm in Argentina. 
As of December 31, 2024, the amount related to these commitments was $39.9 million. 
 
▪ A U.S. subsidiary of the Company entered into a one-year agreement with U.S. Steel Corporation under which it 
is committed to take or pay on a monthly basis a specified minimum volume of steel billets, at prices calculated 
on a monthly basis. As of December 31, 2024, the estimated aggregate contract amount, calculated at current 
prices, stands at approximately $31.2 million. 
 
▪ An Argentine subsidiary of the Company entered into a contract with Usiminas from which it committed to

In addition, Tenaris (i) applied for stand-by letters of credit as well as corporate guarantees covering certain 
obligations of Techgen as described in note 14 (c) and (ii) issued performance guarantees mainly related to long-
term commercial contracts with several customers and Tenaris companies for approximately $4.1 billion as of 
December 31, 2024. 
 
(iii) 
Restrictions on the distribution of profits and payment of dividends 
 
In accordance with Luxembourg Law, the Company is required to transfer a minimum of 5% of its net profit for 
each financial year to a legal reserve is until such reserve equals 10% of the issued share capital. 
 
On April 30, 2024, the extraordinary general meeting of shareholders approved the cancelation of 17,779,302 
ordinary shares held in treasury by the Company and the corresponding reduction of the issued share capital of the 
Company and, accordingly, the legal reserve was proportionally reduced. As of December 31, 2024, this reserve 
remains fully allocated and additional allocations to the reserve are not required under Luxembourg law. Dividends 
may not be paid out of the legal reserve. 
 
The Company may pay dividends to the extent, among other conditions, that it has distributable retained earnings 
calculated in accordance with Luxembourg law and regulations.

Cancellation of title deed in Saudi Steel Pipe Company 
 
In early 2021, the Company learned through the Saudi Ministry of Justice’s online portal that the electronic title 
deeds to certain land plots of its Saudi Arabian subsidiary SSPC had become inactive due to cancellation by court 
order. 
 
The affected land plots, with a total surface of 811,284 square meters, are located in Dammam, Saudi Arabia, and 
were purchased from a private entity on February 2010, pursuant to a written purchase agreement duly executed 
by SSPC in full compliance with the laws of the Kingdom of Saudi Arabia. The purchase of the land occurred before 
Tenaris’s acquisition of a 47.79% interest in SSPC in 2019. The affected plots are not part of the production facility 
of SSPC, have been partially used as a warehouse, and have a carrying value on Tenaris’s financial statements of 
$56.2 million. 
 
As of the date hereof, neither the cancellation nor the court order have been notified to SSPC or otherwise been 
made public by the authorities, and the legal basis for the court order is unknown. On May 4, 2021, SSPC filed a 
petition with an ad-hoc created special committee at the Saudi Ministry of Justice, seeking to have its title deeds 
reinstated. At this time, it is not possible to predict the outcome of this matter.

Foreign exchange control measures in Argentina 
 
Between September 2019 and December 13, 2023, the Argentine government imposed significant restrictions on 
foreign exchange transactions. Although after a new administration took office in Argentina in December 2023 
certain restrictions were eased and other changes to such regulations are expected, at the date of these 
Consolidated Financial Statements the application of existing foreign exchange regulations remains uncertain, and 
the scope and timing of upcoming changes remain unknown. The main currently applicable measures are described 
below: 
 
▪ 
Foreign currency proceeds derived from exports of goods must be sold into the Argentine foreign exchange 
market (“MULC”) and converted into Argentine pesos within 60 days (if made to related parties) or 180 days 
(if made to unrelated parties) from shipment date, or, if collected earlier, within five days of collection. Foreign 
currency proceeds from exports of services must be sold into the MULC and converted into Argentine pesos 
within five business days of collection. As from December 13, 2023, up to 20% of export proceeds can be 
sold for Argentine pesos through securities transactions resulting in a higher implicit exchange rate, as 
described further below. This percentage has remained stable during the twelve-month period ended 
December 31, 2024, but it is unclear if it will be further modified in the short term.  
 
▪ 
Access to the MULC to pay for imports of services that were rendered or accrued as from December 13, 
2023, does not require government approval, but payment is deferred for 30 calendar days as from the date 
of supply or accrual of the service (if the service was rendered by a non-related party) or 180 calendar days 
(if rendered by a related party). 
 

Consolidated Financial Statements 
For the years ended 2024, 2023 and 2022 - all amounts in thousands of U.S. dollars, unless otherwise stated 
 
328 
 
▪ 
Access to the MULC to pay for imports of goods with customs clearance as from December 13, 2023, does 
not require government approval. Payment of the price of such imports is deferred for varying periods of 
time depending on the date of customs clearance; in the case of imports of goods with customs clearance 
on or after October 21, 2024, the price may be paid in full as from the 30th calendar day as from the date of 
custom clearance. Advance payments or at sight cannot be made. In December 2024, the government 
eliminated the tax on imports.  
 
▪ 
Access to the MULC to make dividend payments requires prior Argentine Central Bank approval. When 
required, Argentine Central Bank approvals are rarely, if ever, granted. 
 
The above-described measures substantially limit the ability of Argentine companies to obtain foreign currency and 
make certain payments and distributions out of Argentina through the MULC at the official exchange rate.  
 
Access to foreign currency and transfers out of Argentina can be achieved, however, through securities transactions 
involving bonds or shares with multiple listings, resulting in a different implicit exchange rate, generally higher than 
the official exchange rate. Such transactions are subject to certain restrictions and limits, which change from time 
to time, and often result in a financial loss being generated at the time of making any such transaction. For example, 
in the past, the Argentine Securities Commission imposed several additional restrictions on such securities 
transactions, including a requirement to give prior notice to the Argentine government of any proposed transfer of 
securities outside of Argentina and a limitation on the amount of any such transfers. It is still unclear if or when the 
new Argentine Securities Commission’s authorities will eliminate or loosen the remaining restrictions. 
 
The exchange rate of the Argentine peso against the U.S. dollar devaluated by more than 100% upon the change 
of government in December 2023. Since then and until December 2024, the new Administration maintains a 
“crawling peg” policy by devaluating the Argentine currency at a rate of approximately 2% per month, rate which 
will be reduced to 1% per month as from February 1, 2025. The extent and rate of the crawling peg remains 
unclear. Tenaris’s financial position in Argentine pesos as of December 31, 2024, amounted to a net short exposure 
of approximately $40.6 million. In the event of an additional devaluation, our Argentine subsidiaries, which hold 
U.S. dollar-denominated Argentine bonds for an aggregated value of $217.9 million, may be adversely affected, 
and will also suffer a loss on deferred tax charge as a result of a deterioration on the tax value of their fixed assets. 
At this time, the Company is unable to estimate all impacts of a new devaluation of the Argentine peso against the 
U.S. dollar. 
 
As of December 31, 2024, the total equity of Argentine subsidiaries represented approximately 11% of Tenaris’s 
total equity and the sales made by Argentine subsidiaries during the period ended December 31, 2024, amounted 
approximately to 19% of Tenaris’s total sales. Assets and liabilities denominated in Argentine peso as of December 
31, 2024, are valued at the prevailing official exchange rate. 
 
This context of volatility and uncertainty remains in place as of the issue date of these Consolidated Financial 
Statements. Management continues to monitor closely the evolution of the main variables affecting its business, 
identifying the potential impact thereof on its financial and economic situation and determining the appropriate 
course of action in each case. These Consolidated Financial Statements should be read taking into account these 
circumstances.

34     Business combinations 
 
Acquisition of the Pipe Coating Business Unit of Mattr 
 
▪ 
Acquisition and price determination 
 
On November 30, 2023, Tenaris completed the acquisition of Mattr’s pipe coating business unit and other specific 
assets for $182.6 million paid in cash. Under the purchase contract, the acquisition price was paid based on an 
estimated closing statement and the final price was subject to a true-up adjustment based on actual amounts of 
cash, indebtedness, working capital and certain other items as of the closing date. On July 31, 2024, the parties 
entered into a settlement agreement, pursuant to which the parties agreed that the aggregate shortfall payment 
payable by Mattr to Tenaris amounted to $32.3 million and, accordingly, the final purchase price was $150.2 million. 
 
The business acquired includes nine plants located in Canada, Mexico, Norway, Indonesia, the UAE and the U.S. 
and several mobile concrete plants. The business also includes world-class R&D facilities in Toronto and Norway and 
a wide IP/product portfolio. 
 
The Company consolidated the balances and results of operations of the acquired business as from November 30, 
2023.  
For the twelve-month period ended December 31, 2024, the acquired business contributed revenues of $347.1 
million, represented a minor contribution to Tenaris’s results, and was initially assigned to the Other segment but 
subsequently reclassified to the Tubes segment. 
 
▪ 
Fair value of net assets acquired 
 
The application of the acquisition method requires certain estimates and assumptions, mainly concerning the 
determination of the fair values of the acquired intangible assets, property, plant and equipment as well as the 
liabilities assumed at the date of the acquisition, including the timing and amounts of cash flow projections, the 
revenue growth rates, the customer attrition rates and the discount rate. The fair values determined at the 
acquisition date are based on discounted cash flows and other valuation techniques. 
 
The purchase price allocation was carried out with the assistance of a third-party expert. Following IFRS 3, during 
the twelve month following the acquisition date, the Company continued reviewing the allocation and, based on 
new information related to events or circumstances existing at the acquisition date, made certain adjustments over 
the value of the identifiable assets acquired such as property, plant and equipment, intangible assets, working 
capital and other assets and liabilities. 
 
The allocation of the fair values determined for the assets and liabilities arising from the acquisition is as follows: 
 
Fair value of acquired assets and liabilities as of acquisition date (November 30, 2023) 
in Millions of USD: 
Final 
Preliminary 
Property, Plant and Equipment

The fair value of the net assets acquired shown above amounted to approximately $152.5 million. The preliminary 
purchase price allocation resulted in a goodwill of approximately $13.6 million. However, following the completion 
of the previously mentioned purchase price allocation and a concurrent price adjustment, the business combination 
resulted in a bargain purchase of approximately $2.2 million, recorded in Other operating income. 
 
Acquisition-related costs for the year ended December 31, 2024 and 2023, amounted to $1.3 million and $1.1 
million, respectively and were included in general and administrative expenses. 
 
The price purchase allocation of the remaining business combinations that occurred during 2023 were finalized during 
the year ended December 31, 2024 without any further adjustments.

Share Buyback Programs 
 
First Share Buyback Program 
 
On November 1, 2023, the Company’s board of directors approved a share buyback program of up to $1.2 billion, 
to be executed within a year, with the intention to cancel the ordinary shares acquired through the program. 
 
The share buyback program was carried out under the authority granted by the annual general meeting of 
shareholders held on June 2, 2020, up to a maximum of 10% of the Company’s shares. 
 
For purposes of carrying out each tranche of the first share buyback program, Tenaris entered into non-discretionary 
buyback agreements with primary financial institutions that made trading decisions concerning the timing of the 
purchases of Tenaris’s ordinary shares independently of and uninfluenced by Tenaris and acted in compliance with 
applicable rules and regulations, including the Market Abuse Regulation 596/2014 and the Commission Delegated 
Regulation (EU) 2016/1052. 
 
During the first share buyback program, which was divided into four tranches and ran from November 5, 2023, to 
(and including) August 2, 2024, the Company purchased 71,679,768 ordinary shares, representing 6.07% of the 
Company’s issued share capital at the beginning of the program, for a total consideration of $1.2 billion.  
 
Second Share Buyback Program 
 
On November 6, 2024 the Company’s board of directors approved a follow-on share buyback program of up to 
$700 million, with the intention to cancel the ordinary shares acquired through the program, under the authority 
granted by the annual general meeting of shareholders held on June 2, 2020, up to a maximum of 10% of the 
Company’s shares. 
 
This follow-on share buyback program will cover up to $700 million (excluding incidental transaction fees), subject 
to a maximum of 46,373,915 ordinary shares representing the remainder 3.93% of the Company’s issued share 
capital (measured also as at the launch of the first share buyback program), to complete the maximum of 10% of 
the share capital that may be repurchased by the Company).  
 
During the year ended December 31, 2024, the Company purchased 83,616,548 shares, for $1,441.8 million (net 
of a performance amount of $7.4 million), out of which, $1,439.6 were paid. During the year ended December 31, 
2023, the Company purchased 12,648,091 shares, for a value of $213.7 million (net of a performance amount of 
$0.7 million) out of which, $213.7 were paid. 
 
For purposes of carrying out the second share buyback program, Tenaris entered into non-discretionary buyback 
agreement with a primary financial institution that will make trading decisions concerning the timing of the 
purchases of Tenaris’s ordinary shares independently of and uninfluenced by Tenaris and will act in compliance with 
applicable rules and regulations, including the Market Abuse Regulation 596/2014 and the Commission Delegated 
Regulation (EU) 2016/1052. 
 
On April 30, 2024, the extraordinary shareholders meeting approved the cancellation of 17,779,302 ordinary shares 
held in treasury by the Company, which had been acquired throughout the first tranche of the first share buyback 
program, and resolved to approve the corresponding reduction of the issued share capital of the Company and the 
corresponding amendment of the first paragraph of article 5 of the Company’s articles of association. As a result, 
effective April 30, 2024, the share capital of the Company was reduced from $1,180,536,830 (represented by 
1,180,536,830 shares with a par value of $1 per share) to $1,162,757,528 (represented by 1,162,757,528 shares 
with a par value of $1 per share). 
 
As of December 31, 2024, the Company held 78,485,337 shares as treasury shares. The Company intends to cancel 
all treasury shares purchased under the share buyback programs in due course. 
 
As of December 31, 2024 and 2023, the Company held a liability in connection to the shares to be settled under 
the share buyback programs that amounted to $243.3 million and $86.2 million, respectively, valued at fair value. 
 
Further information on the buyback transactions is available on Tenaris’s corporate website under the Share Buyback 
Program Section.

Climate change 
 
Tenaris carefully assesses the potential impact of climate change and energy transition on its business and on the 
risks to its markets and its tangible and intangible assets, and adapts its business strategy accordingly.  
  
In February 2021 Tenaris set a medium-term target to reduce its carbon emissions intensity rate by 30% by 2030, 
compared to a 2018 baseline, considering Scopes 1 and 2 emissions plus Scope 3 emissions related to raw materials 
and steel purchased from third parties. In February 2025, the baseline for this medium-term target was reset to take 
into account the expanded perimeter of Tenaris through various acquisitions since 2018, the inclusion of intermill 
transportation emissions within the target scope, and additions and other changes in raw material emission factors 
to more accurately represent their use in its operations. The Company aims to achieve this target by using a higher 
proportion of recycled steel scrap in the metallic mix, by making investments to increase energy efficiency and the 
use of renewable energy in its energy requirements, and selective sourcing for raw material and steel purchases. 
 
In particular, a large proportion of these investments in projects aimed at reducing emissions are being directed to 
installing renewable energy capacity for use in the Company’s operations. In October 2023, following an investment 
of approximately $200 million, Tenaris put into operation a wind farm in Argentina, which supplies, through the 
interconnected grid, 103.2 MW of power, or close to 50% of their total electric power requirements, to its industrial 
facilities in Campana. In November 2023, the Company’s Board of Directors approved an investment plan to build 
a second wind farm in Argentina at a cost of approximately $214 million, which would supply a further 30% of the 
current energy requirements of its facilities in Campana.  
 
Tenaris encourages the use of sustainable practices among its suppliers and, in March 2023, it adopted a Sustainable 
Sourcing Policy to enhance its efforts in this area. The new Sustainability Sourcing Policy will help Tenaris to 
understand better the real emission levels of its suppliers and identify opportunities for improvement in line with its 
reduction target. 
 
The medium-term target forms part of a broader objective of decarbonizing the Company’s operations and reaching 
carbon neutrality. At the same time, the Company is increasing its sales for low-carbon energy applications, such 
as hydrogen, geothermal and CCS. These sales currently account for a relatively small proportion of overall sales 
but are expected to grow in the coming years.  
 
In its assessment of climate change and energy transition potential impact on operations, Tenaris also considers that 
the countries in which it operates and its customers are also establishing their own decarbonization strategies and 
objectives, and that some customers are requesting specific information from their suppliers, including Tenaris, 
concerning the carbon emissions and Environmental, Social and Governance (“ESG”) practices in their supply chain, 
and that they may adjust their supply practices in light of that information.  
 
The recoverable value assessments performed by the Company for purposes of the preparation of these financial 
statements reflects management’s views on the energy transition and climate change and their potential medium- 
and long-term impact on Tenaris’s operations and its sales. In addition, the Company carefully monitors the 
medium- and long-term outlook scenarios published by leading industry experts on how the energy transition could 
affect global demand for energy and oil and gas and how this could affect the global demand for tubular products 
and its sales. Furthermore, estimates and assumptions used in the Company’s impairment tests over long-lived 
assets and goodwill, useful lives of assets, capital and research and development expenditures, inventory valuation, 
recovery of deferred tax assets and provisions, and contingent liabilities are based on available information and 
current government regulations on energy transition and climate-related matters, as well as on Tenaris’s current 
short-term investment plans. As of the date of these financial statements, the Company does not believe that 
climate-related matters should trigger any material adjustments to the conclusions of its impairment tests or the 
valuation of the above mentioned areas.

37     Events after the reporting period11 
 
Recently Announced 25% Tariff on Steel Imports in the United States 
 
Early in 2025, the U.S. government imposed a 25% tariff on virtually all imports of steel and steel derivatives, 
revoking previously negotiated country-specific exemptions and quota arrangements. As a result, all previously 
exempted or quota-managed countries became subject to the full 25% tariff on their steel exports to the United 
States.  
 
In addition, on February 1, 2025, the U.S. government announced the imposition, through the International 
Emergency Economic Powers Act (“IEEPA”), of across-the-board tariffs applicable to all products imported from 
Mexico, Canada and China (with the exception, as of the date of this Consolidated Financial Statements), of Mexican 
and Canadian products that comply with USMCA preferential rules of origin). These tariffs could apply to certain 
products that Tenaris and other companies are currently importing under previously granted exclusions or tariff-free 
quotas.  
 
In light of the foregoing uncertainties, at this time, Tenaris is unable to predict the evolution or ultimate outcome 
of these developments or to quantify the impact that the new tariffs and measures could have on its business or 
financial condition. 
 
 
Annual Dividend Proposal 
 
Upon approval of the Company´s annual accounts on April 1, 2025, the Board of Directors intends to propose, for 
the approval of the Annual General Shareholders' meeting to be held on May 6, 2025, the payment of an annual 
dividend of $0.83 per outstanding share ($1.66 per ADS), or approximately $0.9 billion, which includes the interim 
dividend of $0.27 per outstanding share ($0.54 per ADS) or approximately $0.3 billion, paid on November 20, 2024. 
If the annual dividend is approved by the shareholders, a dividend of $0.56 per outstanding share ($1.12 per ADS), 
or approximately $0.6 billion will be paid on May 21, 2025, with record date on May 20, 2025. These Consolidated 
Financial Statements do not reflect this dividend payable. 
 
 
Share buyback Second Program Completion 
 
On March 4, 2025, the Company announced the completion of its second Share Buyback Program. During the 
Program, which ran from November 11, 2024, until March 4, 2025, the Company purchased a total of 36,862,132 
ordinary shares, for a total consideration of approximately $691.6 million (net of a performance amount of 
approximately $8.4 million). As of March 4, 2025, the Company held 90,762,598 treasury shares. The Company 
intends to cancel all treasury shares purchased under the share buyback programs in due course.

NOTES TO THE ANNUAL ACCOUNTS  
 
Note 1 – General information 
 
Tenaris S.A. (the “Company” or “Tenaris”) was established on December 17, 2001 under the name of Tenaris 
Holding S.A. as a public limited liability company under Luxembourg’s 1929 holding company regime (société 
anonyme holding). On June 26, 2002, the Company changed its name to Tenaris S.A. On January 1, 2011, the 
Company became an ordinary public limited liability company (société anonyme). 
 
Tenaris’s object is to invest in companies that mainly manufacture and market steel tubes and other related 
businesses.  
 
The financial year starts on January 1 and ends on December 31 of each year. 
 
Tenaris prepares and publishes consolidated financial statements which include further information on Tenaris and 
its subsidiaries. The consolidated financial statements are available at the registered office of the Company, 26, 
Boulevard Royal – 4th floor, L-2449, Luxembourg, Grand-Duchy of Luxembourg.  
 
 
Note 2 – Summary of significant accounting policies  
 
2.1 
Basis of presentation 
 
These annual accounts have been prepared in accordance with Luxembourg legal and regulatory requirements 
under the historical cost convention.  
 
Accounting policies and valuation rules are, besides the ones laid down by the law of 19 December 2002, 
determined and applied by the Board of Directors. 
 
The preparation of these annual accounts requires management to make certain accounting estimates and 
assumptions that might affect the reported amounts of assets and liabilities and the disclosure of contingent 
liabilities at the reporting dates, and the reported amounts of income and charges during the reporting years. Actual 
results may differ from these estimates. The main area involving significant estimates or judgements is the valuation 
of financial assets. During the year there were no material changes in the significant accounting estimates. 
 
2.2 
Foreign currency translation 
 
The books and records are maintained in United States Dollars (“USD” or “$”) and the annual accounts have been 
prepared in accordance with the valuation rules and accounting policies described below. Unless otherwise stated, 
all amounts presented in these annual accounts are in USD, which is the reporting currency of the Company. 
 
Assets and liabilities denominated in currencies other than the USD are translated into USD at the rate of exchange 
at the balance sheet date except for tangible and intangible fixed assets and shares in affiliated undertakings which 
remain at the historical exchange rate on the day of incorporation. The resulting gains or losses are reflected in the 
profit and loss account for the financial year when they are realized. Solely the unrealized exchange losses are 
recorded in the profit and loss account. Income and expenses in currencies other than the USD are translated into 
USD at the exchange rate prevailing at the date of each transaction. 
 
2.3 
Financial assets 
 
Shares in affiliated undertakings are valued at purchase or contribution price including the expenses incidental 
thereto. 
 
The Company conducts value adjustment tests on its financial assets in accordance with Luxembourg legal and 
regulatory requirements. 
 
In case of other than a temporary decline in respect of the financial assets value, its carrying value will be reduced 
to recognize this decline. If there is a change in the reasons for which the value adjustments were made, these 
adjustments could be reversed, if appropriate.

2.4 
Debtors 
 
Debtors are valued at their nominal value. They are subject to value adjustments whenever their recovery is 
compromised. These value adjustments are not continued if the reasons for which the value adjustments were made 
have ceased to apply. 
 
2.5 
Investments 
 
Investments represent own shares and are valued at purchase price including the expenses incidental thereto. The 
carrying amount is impaired if a decline of the value is noted or a former impairment reversed if the reason for the 
value decline cease to exist. 
 
2.6 
Cash at bank and in hand 
 
Cash at bank and in hand mainly comprise cash at bank and liquidity funds.

(*) On December 7, 2010, Tenaris entered into a master credit agreement with Tenaris Global Services and 
Investments S.à r.l. pursuant to which, upon request from Tenaris, Tenaris Global Services and Investments S.à r.l. 
may, but shall not be required to, from time to time, make loans to Tenaris. Any loan under the master credit 
agreement may be repaid or prepaid from time to time through a reduction of the capital of Tenaris Global Services 
and Investments S.à r.l. by an amount equivalent to the amount of the loan then outstanding (including accrued 
interest). As a result of reductions in the capital of Tenaris Global Services and Investments S.à r.l. made during the 
financial year ended December 31, 2024, in connection with cancellations of loans to Tenaris, the value of the 
participation of Tenaris in Tenaris Global Services and Investments S.à r.l. decreased by $2,176 million. These loans 
were granted to finance the payment of dividend distributions, share buyback programs and operating expenses. 
 
(**) The management of the Company has assessed the recoverable value of its investment and recorded an 
impairment reversal of $1,622.8 million as of December 31, 2024.

Note 4 – Capital and reserves 
 
The Company has an authorized share capital of a single class of 2.5 billion shares with a nominal value of $1.00 
per share. Total ordinary shares issued as of December 31, 2024 and 2023 were 1,162,757,528 and 1,180,536,830, 
respectively, with a par value of $1.00 per share with one vote each.  
 
On April 30, 2024, the extraordinary general meeting of shareholders approved the cancellation of 17,779,302 
ordinary shares and the corresponding reduction of the issued share capital of the Company. 
 
The Board of Directors is authorized until June 12, 2025, to increase the issued share capital, through issues of 
shares within the limits of the authorized capital. 
 
Following the completion of the corporate reorganization, and upon its conversion into an ordinary Luxembourg 
holding company, the Company recognized a special fiscal reserve for tax purposes. 
 
Note 5 – Legal reserve 
 
In accordance with Luxembourg law, the Company is required to set aside a minimum of 5% of its annual net profit 
for each financial year to a legal reserve. This requirement ceases to be necessary once the balance on the legal 
reserve has reached 10% of the issued share capital. The Company’s reserve has already reached this 10%. If the 
legal reserve later falls below the 10% threshold, at least 5% of net profits must be allocated to the reserve. The 
legal reserve is not available for distribution to the shareholders. 
 
On April 30, 2024, the extraordinary general meeting of shareholders approved the cancellation of 17,779,302 
ordinary own shares held by the Company and the corresponding reduction of the issued share capital of the 
Company and, accordingly, the legal reserve was proportionally reduced. After the before mentioned capital 
reduction, this reserve remains fully allocated. 
 
Note 6 – Reserve for own shares 
 
The Company purchased during the year 2024 and 2023 own shares for an amount of $1,441,843,370 and 
$213,738,593, respectively. 
 
In accordance with Luxembourg law, as of December 31, 2024 and 2023, the Company maintains a non-
distributable reserve included in the account “Reserve for own shares” for an amount of $1,355,651,125 and 
$213,738,593, respectively. 
 
Note 7 – Distributable amounts 
 
Dividends may be paid by Tenaris upon the ordinary shareholders’ meeting approval to the extent that it has 
distributable retained earnings calculated in accordance with Luxembourg law. 
 
At December 31, 2024, the Company’s profit brought forward after the income and the deduction of the interim 
dividend for the financial year totaled approximately $14,519.4 million and the share premium reserve which is also 
distributable, amounted to $609.7 million. 
 
At December 31, 2023, the Company’s profit brought forward after the income and the deduction of the interim 
dividend for the financial year totaled approximately $15,229.6 million and the share premium reserve which is also 
distributable, amounted to $609.7 million. 
 
Note 8 – Dividend payment 
 
On November 6, 2024, the Company’s Board of Directors approved an interim dividend of $0.27 per outstanding 
share, or approximately $299 million, paid on November 20, 2024.

the share buyback programs. 
 
Note 14 – Taxes  
 
The Company is liable for all taxes applicable to a Luxembourg "Société Anonyme". For the financial year ended 
December 31, 2024, the Company did not realize any profits subject to tax in Luxembourg. 
 
In December 2021, the Organization for Economic Co-operation and Development (“OECD”) released the Pillar 
Two model rules (the Global Anti-Base Erosion rules, or “GloBE”) to reform international corporate taxation. 
Following Pillar Two OECD’s initiative, the European Union adopted in December 2022 a directive to impose a global 
minimum taxation for multinational companies in the Union, to be effective as from 2024. On December 20, 2023, 
Pillar Two legislation was adopted in Luxembourg, and came into effect as from January 1, 2024.  
  
The Company is within the scope of these rules, and therefore, is required to calculate its GloBe effective tax rate 
for each jurisdiction in which it is present and is liable to pay a top-up tax for the difference between its Globe 
effective tax rate per jurisdiction and the 15% minimum rate. No current tax impacts have arisen in the Annual 
Accounts as of December 31, 2023, due to the application of Pillar Two rules, as they are applicable as from 2024 
in jurisdictions relevant for the Company. For the year 2024, the Company recognized an estimated current tax 
expense related to Pillar Two, amounting to approximately $81 million. 
 
Note 15 – Parent Company 
 
Tenaris’s controlling shareholders as of December 31, 2024 were as follows: 
  
• 
San Faustin S.A., a Luxembourg société anonyme, owned 713,605,187 shares in the Company, 
representing 61.37% of the Company’s share capital and 65.81% of the voting rights. 
  
• 
San Faustin owned all of its shares in the Company through its wholly-owned subsidiary Techint Holdings 
S.à.r.l., a Luxembourg société à responsabilité limitée (“Techint”), who is the holder of record of the above-
mentioned Tenaris shares. 
  
• 
Rocca & Partners Stichting Administratiekantoor Aandelen San Faustin, a private foundation located in the 
Netherlands (Stichting) (“RP STAK”) held voting shares in San Faustin sufficient in number to control San 
Faustin. 
  
• 
No person or group of persons controls RP STAK.

Note 16 – 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 the nationalization proceeds received by Ternium (in which the Company 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. 
  
On October 9, 2020, the court granted in part and denied in part the defendants’ motions to dismiss. The court 
partially granted and partially denied the motion to dismiss the claims against the Company and its Chairman and 
CEO. In addition, the court granted the motions to dismiss as to all claims against San Faustin, Techint, and Tenaris’s 
former CFO. 
  
On November 11, 2022, the parties filed a joint notice of settlement announcing a settlement in principle of all 
claims in the action, subject to finalizing the settlement agreements and court approval. The parties’ agreement in 
principle provided that, in exchange for dismissal of the action and customary releases from class members and 
with no admission of liability by Tenaris or Mr. Rocca, Tenaris shall pay to the class $9.5 million (inclusive of legal 
fees to lead plaintiff’s counsel). 
  
On April 10, 2023, the court granted preliminary approval to the class settlement. The final settlement approval 
hearing was set for October 19, 2023, and on that date the court ordered that, prior to granting final settlement 
approval, the lead plaintiffs submit an update letter advising the court of the status of the claims processing. After 
the submission was made, on April 22, 2024, the court granted final approval to the settlement and closed the 
case. 
 
Note 17 – 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, 2023, the judge granted summary judgment in favor of 
Global Tubing, concluding that the patents at issue are unenforceable due to inequitable conduct during the patent 
prosecution process. TCT appealed this judgment, and Global Tubing appealed a previous ruling of the judge. Global 
Tubing also filed a brief seeking to recover attorneys’ fees, without specifying the amount of those fees. Although 
it is not possible to predict the final outcome of this matter, the Company believes that any potential losses arising 
from this case will not be material. 
 
Note 18 – Petrobras-related proceedings and claims 
 
Upon learning that Brazilian, Italian and Swiss authorities were investigating whether certain payments were made 
prior to 2014 from accounts of entities presumably associated with affiliates of the Company to accounts allegedly 
linked to individuals related to Petróleo Brasileiro S.A. (“Petrobras”) and whether any such payments were intended 
to benefit the Company’s Brazilian subsidiary Confab, the Audit Committee of the Company's Board of Directors 
engaged external counsel in connection with the Company’s review of these matters. In addition, the Company 
voluntarily notified the U.S. Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice 
(“DOJ”) in October 2016. The Company conducted, with the assistance of external counsel, an internal investigation 
and found no evidence corroborating any involvement by the Company or its directors, officers or employees in 
respect of improper payments. An internal investigation commissioned by Petrobras also found no evidence that 
Confab obtained any unfair commercial benefit or advantage from Petrobras in return for payments, including 

Annual Accounts – Tenaris S.A. 
December 31, 2024 and 2023 - all amounts in U.S. dollars, unless otherwise stated 
 
353 
 
improperly obtained contracts. On June 2, 2022, the Company resolved the investigation by the SEC, and the DOJ 
informed that it had closed its parallel inquiry without taking action. Under the settlement with the SEC, the 
Company neither admits nor denies the SEC’s findings and on June 24, 2022, paid $53.1 million in disgorgement 
and prejudgment interest and $25 million for a civil penalty to conclude the matter. 
 
In July 2019, the Company learned that the public prosecutors’ office of Milan, Italy, had completed a preliminary 
investigation into the same alleged payments and had included in the investigation, among other persons, the 
Company’s Chairman and chief executive officer, two other board members, Gianfelice Rocca and Roberto Bonatti, 
and the Company’s controlling shareholder, San Faustin. The Company was not a party to the proceedings. On 
March 22, 2022, upon completion of the evidentiary phase of the trial, the acting prosecutor requested the first-
instance court in Milan in charge of the case to impose sanctions on our Chairman and chief executive officer, on 
the other two board members, and on San Faustin. On May 26, 2022, the first-instance court dismissed the case 
brought by the public prosecutor against the defendants for lack of jurisdiction and stated that the criminal 
proceeding should not have been initiated. On February 22, 2024, the court of appeals referred the case to the 
court of cassation, which, on May 23, 2024, confirmed the decision of the first-instance court and closed the case. 
 
In June 2020, the Brazilian public prosecutors’ office requested the indictment of several individuals, including three 
executives or former executives of Confab and a former agent of Confab, charging them with the alleged crimes 
of corruption in relation to contracts executed between 2007 and 2010, and money laundering in relation to 
payments between 2009 and 2013. On December 11, 2024, the Confab executives were acquitted. The acquittal 
has already been appealed, so the criminal proceedings continue to be underway. Neither the Company nor Confab 
is a party to these criminal proceedings. 
 
In addition, Petrobras and the Brazilian public prosecutors filed civil claims for alleged damages arising from the 
same events against, among others, Confab and the Confab executives named in the criminal proceedings referred 
to above. Confab became aware of these civil claims in September 2022. As of December 31, 2024, the aggregate 
amount of these claims was estimated at BRL193.2 million (or approximately $31.2 million). The plaintiffs also seek 
that Confab be prohibited from contracting with, or receiving benefits or exemptions from, the Brazilian state for 
an unspecified term. Confab believes these claims do not address either the defence arguments or the evidence 
available to the plaintiffs in Brazil and presented in other jurisdictions and is contesting them. At this stage, the 
Company cannot predict the outcome of these civil proceedings. 
 
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 the same purported irregularities. Confab received notice of 
these proceedings in February 2025, and believes that the General Controllers’ Office’s allegations do not address 
either the defence arguments or the evidence available to the plaintiffs in Brazil and presented in other jurisdictions. 
Although the Company is defending itself, it cannot predict the outcome of these administrative proceedings. 
 
Note 19 – Atlas Operating Product Claim Liability 
 
On November 15, 2024, Atlas Operating LLC (“Atlas Operating”) filed a third-party claim against among others, 
the Company and certain of the Company’s U.S. subsidiaries for negligence, strict liability, breach of warranty and 
misrepresentation following three alleged casing breaches on or about November 18, 2022. Atlas Operating claims 
to have purchased, from Atlas Tubular, LLC, casing that was designed, manufactured, supplied and distributed by 
the Tenaris entities and other defendants. Atlas Operating asserts damages in the order of $5 million. Tenaris’s 
insurance carrier has been notified of the claim. At this point, the Company, cannot predict the ultimate resolution 
of the matter. 
 
Note 20 – Off balance sheet commitments 
 
Under a loan agreement between the associated company Techgen S.A. de C.V. (“Techgen”) and various lenders, 
the Company issued guarantees covering the funding obligations that as of December 31, 2024 and 2023, 
amounted to approximately $10.9 million.

Note 21 – Climate change 
 
Tenaris carefully assesses the potential impact of climate change and energy transition on its business and on the 
risks to its markets and its tangible and intangible assets, and adapts its business strategy accordingly.  
  
In February 2021 Tenaris set a medium-term target to reduce its carbon emissions intensity rate by 30% by 2030, 
compared to a 2018 baseline, considering Scopes 1 and 2 emissions plus Scope 3 emissions related to raw materials 
and steel purchased from third parties. In February 2025, the baseline for this medium-term target was reset to take 
into account the expanded perimeter of Tenaris through various acquisitions since 2018, the inclusion of intermill 
transportation emissions within the target scope, and additions and other changes in raw material emission factors 
to more accurately represent their use in its operations. The Company aims to achieve this target by using a higher 
proportion of recycled steel scrap in the metallic mix, by making investments to increase energy efficiency and the 
use of renewable energy in its energy requirements, and selective sourcing for raw material and steel purchases. 
  
In particular, a large proportion of these investments in projects aimed at reducing emissions are being directed to 
installing renewable energy capacity for use in the Company’s operations. In October 2023, following an investment 
of approximately $200 million, Tenaris put into operation a wind farm in Argentina, which supplies, through the 
interconnected grid, 103.2 MW of power, or close to 50% of their total electric power requirements, to its industrial 
facilities in Campana. In November 2023, the Company’s Board of Directors approved an investment plan to build 
a second wind farm in Argentina at a cost of approximately $214 million, which would supply a further 30% of the 
current energy requirements of its facilities in Campana. 
  
Tenaris encourages the use of sustainable practices among its suppliers, and in March 2023, it adopted a Sustainable 
Sourcing Policy to enhance its efforts in this area. The new Sustainability Sourcing Policy will help Tenaris to 
understand better the real emission levels of its suppliers and identify opportunities for improvement in line with its 
reduction target. 
  
The medium-term target forms part of a broader objective of decarbonizing the Company’s operations and reaching 
carbon neutrality. At the same time, the Company is increasing its sales for low-carbon energy applications, such 
as hydrogen, geothermal and carbon capture and storage. These sales currently account for a relatively small 
proportion of overall sales but are expected to grow in the coming years. 
  
In its assessment of climate change and energy transition potential impact on operations, Tenaris also considers that 
the countries in which it operates and its customers are also establishing their own decarbonization strategies and 
objectives, and that some customers are requesting specific information from their suppliers, including Tenaris, 
concerning the carbon emissions and Environmental, Social and Governance (“ESG”) practices in their supply chain, 
and that they may adjust their supply practices in light of that information. 
  
The recoverable value assessments performed by the Company for purposes of the preparation of these Annual 
Accounts reflects management’s views on the energy transition and climate change and their potential medium- 
and long-term impact on Tenaris’s operations and its sales. In addition, the Company carefully monitors the 
medium- and long-term outlook scenarios published by leading industry experts on how the energy transition could 
affect global demand for energy and oil and gas and how this could affect the global demand for tubular products 
and its sales. Furthermore, estimates and assumptions used in the Company’s valuations are based on available 
information and current government regulations on energy transition and climate-related matters, as well as on 
Tenaris’s current short-term investment plans. As of the date of these Annual Accounts, the Company does not 
believe that climate-related matters should trigger any material adjustments to the conclusions of its impairment 
tests or the valuation of the above-mentioned areas.

Note 22 – Share buyback program 
 
First Share Buyback Program 
  
On November 1, 2023, the Company’s board of directors approved a share buyback program of up to $1.2 billion, 
to be executed within a year, with the intention to cancel the ordinary shares acquired through the program. 
  
The share buyback program was carried out under the authority granted by the annual general meeting of 
shareholders held on June 2, 2020, up to a maximum of 10% of the Company’s shares. 
  
For purposes of carrying out each tranche of the first share buyback program, Tenaris entered into non-discretionary 
buyback agreements with primary financial institutions that made trading decisions concerning the timing of the 
purchases of Tenaris’s ordinary shares independently of and uninfluenced by Tenaris and acted in compliance with 
applicable rules and regulations, including the Market Abuse Regulation 596/2014 and the Commission Delegated 
Regulation (EU) 2016/1052. 
  
During the first share buyback program, which was divided into four tranches and ran from November 5, 2023, to 
August 2, 2024, the Company purchased 71,679,768 ordinary shares, representing 6.07% of the Company’s 
issued share capital at the beginning of the program, for a total consideration of $1.2 billion. 
  
Second Share Buyback Program 
  
On November 6, 2024, the Company’s board of directors approved a follow-on share buyback program of up to 
$700 million, with the intention to cancel the ordinary shares acquired through the program, under the authority 
granted by the annual general meeting of shareholders held on June 2, 2020, up to a maximum of 10% of the 
Company’s shares. 
  
This follow-on share buyback program covers up to $700 million (excluding incidental transaction fees), subject to 
a maximum of 46,373,915 ordinary shares representing the remainder 3.93% of the Company’s issued share capital 
(measured also as at the launch of the first share buyback program), to complete the maximum of 10% of the share

Alternative performance measures 
EBITDA, Earnings before interest, tax, depreciation and amortization 
EBITDA provides an analysis of the operating results excluding depreciation and amortization and impairments, as 
they are non-cash variables which can vary substantially from company to company depending on accounting 
policies and the accounting value of the assets. EBITDA is an approximation to pre-tax operating cash flow and 
reflects cash generation before working capital variation. EBITDA is widely used by investors when evaluating 
businesses (multiples valuation), as well as by rating agencies and creditors to evaluate the level of debt, 
comparing EBITDA with net debt.  
 
EBITDA is calculated in the following manner: 
 
EBITDA = Net income for the period + Income tax charge +/- Equity in Earnings (losses) of non-consolidated 
companies +/- Financial results + Depreciation and amortization +/- Impairment charge/(reversal) 
 
EBITDA is a non-IFRS alternative performance measure.

Net cash / (debt) position 
 
This is the net balance of cash and cash equivalents, other current investments and fixed income investments held 
to maturity less total borrowings. It provides a summary of the financial solvency and liquidity of the company. 
Net cash / (debt) is widely used by investors and rating agencies and creditors to assess the company’s leverage, 
financial strength, flexibility and risks. 
 
Net cash/ debt is calculated in the following manner: 
 
Net cash= Cash and cash equivalents + Other investments (Current and Non-Current) +/- Derivatives hedging 
borrowings and investments – Borrowings (Current and Non-Current). 
 
Net cash is a non-IFRS alternative performance measure.
