- Profitability: Operating income fell 14% to US$1.13 bn (18.9% margin vs. 19.6%). Net income slipped 3% to US$1.06 bn; however EPS rose 4% to US$0.97 owing to share buybacks.
- EBITDA: US$1.43 bn; margin 23.8% vs. 26.7% (ex-2024 litigation charge) – a 21% absolute decline.
- Cash & Liquidity: Operating cash flow US$1.49 bn; capex US$309 m → free cash flow US$1.20 bn. Net cash position solid at US$3.73 bn.
- Capital return: US$0.83/sh annual dividend (US$0.56 balance paid May-25) and US$0.47 bn shares bought back in H1; a new US$1.2 bn buyback launched in June.
- Balance sheet: Equity US$16.79 bn; net working-capital released US$0.25 bn.
- Outlook: Management guides a “moderate” 2H revenue decline and margin pressure from recently doubled U.S. steel tariffs (25%→50%) and lower drilling activity.
Key risks disclosed include tariff escalation, volatile OCTG demand, climate-related regulation, litigation, geopolitical disruptions and cybersecurity threats.
Q2 2025 highlights: Net sales rose 6 % QoQ to $3.09 bn but were 7 % below Q2 2024. EBITDA reached $733 m (+5 % QoQ) with a 23.7 % margin. Net income increased to $542 m (+5 % QoQ, +56 % YoY). Tubes revenue advanced 6 % sequentially as higher OCTG prices offset a 1 % volume dip; welded volumes fell 16 % QoQ.
Cash & returns: Operating cash flow of $673 m and capex of $135 m delivered free cash flow of $538 m. After paying $600 m in dividends and executing $237 m of share buybacks, Tenaris ended the quarter with a strong $3.7 bn net cash position. EPS per ADS reached $0.99.
First-half view: Sales dropped 11 % YoY to $6.0 bn as North-American pricing weakened; EBITDA margin slid to 23.8 %. Free cash flow totalled $1.2 bn and EPS still grew 4 % due to reduced share count.
Outlook: Management foresees a moderate sales decline and margin pressure in H2 2025 owing to softer drilling activity and higher U.S. steel tariffs, though firmer OCTG pricing should offer partial relief.
