LUXEMBOURG, Aug. 05, 2026 (GLOBE NEWSWIRE) -- Tenaris S.A. (NYSE and Mexico: TS and EXM Italy: TEN) (“Tenaris”) today announced its results for the quarter ended June 30, 2026 in comparison with its results for the quarter ended June 30, 2025.

Summary of 2026 Second Quarter Results
(Comparison with first quarter of 2026 and second quarter of 2025)

In the second quarter, our sales decreased 4% sequentially reflecting, to a large extent, the postponement of shipments to customers in the Middle East due to the effective closure of the strait of Hormuz for most of the period. Our EBITDA margin also decreased with higher unitary logistic costs, lower absorption of fixed costs and rising raw material costs.

During the quarter, our free cash flow amounted to $396 million and, after spending $606 million on dividends, our net cash position amounted to $3.6 billion at June 30, 2026.

Interim Dividend Payment

Our board of directors approved the payment of an interim dividend of $0.59 per share ($1.18 per ADS), or approximately $600 million, according to the following timetable:

• Payment date: November 25, 2026
• Record date: November 24, 2026
• Ex-dividend for securities listed in the United States: November 24, 2026
• Ex-dividend for securities listed in Europe and Mexico: November 23, 2026
  
  

Market Background and Outlook

Oil and gas drilling activity has been increasing in the USA, Canada and Argentina. In addition, customers around the world are moving forward with investments in cost-competitive offshore projects, as the industry increases its focus on security and diversification of supply.

In the United States, OCTG prices have been increasing in response to higher demand and to offset higher raw material and logistic costs.

In the Middle East, the conflict continues to cause disruption to shipping through the strait of Hormuz. Drilling activity in Iraq, Kuwait and Qatar has been severely affected, while, in Saudi Arabia and the UAE, it has been largely maintained.

In the second half, we expect our sales and EBITDA to remain in line with the first half, despite sales continuing to be affected by lower shipments to the Middle East and higher raw material costs. There may be some upside if the shipping disruption at the strait of Hormuz ends before the end of the year. The third quarter will be additionally affected by seasonality and product mix effects, while the fourth quarter will benefit from higher prices and volumes in most regions.

Changes in the Company's Board of Directors

The Company’s Board of Directors has been informed at its most recent meeting that Mr. Jaime Serra Puche has resigned as a member of the Board and of its Audit Committee, for personal reasons, and that, due to other commitments, Mr. Germán Curá has resigned as Vice Chair responsible for overseeing Tenaris’s Sustainability Strategy but will continue to serve as a director.

Analysis of 2026 Second Quarter Results

Tubes

The following table indicates, for our Tubes business segment, sales volumes of seamless and welded pipes for the periods indicated below:

The following table indicates, for our Tubes business segment, net sales by geographic region, operating income and operating income as a percentage of net sales for the periods indicated below:

Net sales of tubular products and services decreased 4% sequentially and year on year, in line with the volume variation as average selling prices remained stable. Sequentially, in North America, higher sales of OCTG in the United States largely compensated for lower OCTG sales in Canada and Mexico. In South America, lower sales of OCTG in Brazil were partially compensated by an increase in Guyana, Suriname and Venezuela, while, in Argentina, lower sales for pipelines were compensated by higher sales of OCTG. In Europe, we had higher sales of OCTG in Turkey and the start of deliveries of offshore line pipe to the Sakarya Black Sea development. In Asia Pacific, Middle East and Africa, sales declined with the postponement of deliveries to Kuwait and Iraq and lower deliveries to North Africa following a concentration of such deliveries in the previous quarter.

Operating results from tubular products and services amounted to a gain of $465 million in the second quarter of 2026 compared to a gain of $545 million in the previous quarter and a gain of $554 million in the second quarter of 2025. Operating income in the quarter decreased due to higher unitary logistic costs, lower absorption of fixed costs and rising raw material costs.

Others

The following table indicates, for our Others business segment, net sales, operating income and operating income as a percentage of net sales for the periods indicated below:

Net sales of other products and services decreased 3% sequentially and decreased 1% year on year. Sequentially sales declined mainly due to lower sales of oilfield services in Argentina.

Sequentially, the increase in SG&A is mainly due to higher services and fees and increased unitary logistic costs associated to the closure of the strait of Hormuz.

Financial results amounted to a gain of $32 million in the second quarter of 2026, compared to a gain of $50 million in the previous quarter and a gain of $32 million in the second quarter of 2025. Financial results of the quarter are mainly attributable to a $41 million net finance income from the net return of our portfolio investments, net of a $9 million loss from foreign exchange transactions and derivatives.

Equity in earnings of non-consolidated companies generated a gain of $48 million in the second quarter of 2026, compared to a gain of $33 million in the previous quarter and a gain of $33 million in the second quarter of 2025. These results are mainly derived from our participation in Ternium (NYSE:TX) and Usiminas.

Analysis of 2026 First Half Results

Our sales in the first half of 2026 increased 1% compared to the first half of 2025 as volumes of tubular products shipped decreased 1% and tubes average selling prices increased 2% driven by price increases in North America while sales in the Others segment increased 3%. EBITDA in the first half of 2026 was negatively affected by the impact of tariff costs in the United States. Earnings per share increased 4% following the reduction of outstanding shares due to the share buyback.

Cash flow provided by operating activities amounted to $1.1 billion during the first half of 2026, net of an increase in working capital of $84 million. After capital expenditures of $236 million, our free cash flow amounted to $0.9 billion. Following a dividend payment of $606 million and share buybacks for $90 million in the semester, our net cash position amounted to $3.6 billion at the end of June 2026.

Net sales of other products and services increased 3% to $333 million in the first half of 2026, compared to $322 million in the first half of 2025. The increase is mainly due to additional sales of excess raw materials.

Operating results from other products and services amounted to a gain of $68 million in the first half of 2026, compared to a gain of $65 million in the first half of 2025. These results were primarily driven by our oilfield services business in Argentina and by sales of sucker rods, pipes for plumbing applications, and coiled tubing.

Selling, general and administrative expenses, or SG&A, amounted to $951 million in the first half of 2026 and $941 million in the first half of 2025 in both cases representing 15.7% of sales.

Other operating results amounted to a loss of $6 million in the first half of 2026, compared to a loss of $50 thousand in the first half of 2025. The six million loss is mainly due to the provision for ongoing litigation related to the acquisition of a participation in Usiminas.

Financial results amounted to a gain of $83 million in the first half of 2026, compared to a gain of $67 million in the first half of 2025. Financial results of the semester are mainly attributable to a $94 million net finance income from the net return of our portfolio investments.

Exhibit I – Alternative performance measures

Alternative performance measures should be considered in addition to, not as substitute for or superior to, other measures of financial performance prepared in accordance with IFRS.

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 recurring 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 charges +/- Equity in Earnings (losses) of non-consolidated companies +/- Financial results + Depreciation and amortization +/- Impairment charges/(reversals).

EBITDA is a non-IFRS alternative performance measure.

Free Cash Flow

Free cash flow is a measure of financial performance, calculated as operating cash flow less capital expenditures. FCF represents the cash that a company is able to generate after spending the money required to maintain or expand its asset base.

Free cash flow is calculated in the following manner:

Free cash flow = Net cash (used in) provided by operating activities - Capital expenditures.

Free cash flow is a non-IFRS alternative performance measure.

Net Cash / (Debt)

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/debt is a non-IFRS alternative performance measure.

Operating working capital days

Operating working capital is the difference between the main operating components of current assets and current liabilities. Operating working capital is a measure of a company’s operational efficiency, and short-term financial health.

Operating working capital days is calculated in the following manner:

Operating working capital days = [(Inventories + Trade receivables – Trade payables – Customer advances) / Annualized quarterly sales ] x 365.

Operating working capital days is a non-IFRS alternative performance measure.
