Key Financial Metrics

Note: Borrowings calculated as sum of Current Borrowings ($1,124,061) and Non-current Borrowings ($214,569) for Q1 2011.

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased 41.8% year-over-year, driven by higher volumes and prices across all segments, particularly in the Tubes segment which generated $1.97 billion in sales.
• Profitability: Operating income rose 42.7% to $441.5 million. Gross margin improved to 38.3% in Q1 2011 compared to 39.8% in Q1 2010, though absolute gross profit increased significantly due to volume.
• Cash Flow: Net cash provided by operating activities decreased significantly to $165.7 million from $436.3 million in the prior year, primarily due to a $392.9 million use of cash for changes in working capital (compared to a $124.2 million source in 2010).
• Capital Expenditures: Capital expenditures increased 33.3% to $210.6 million, reflecting continued investment in capacity expansion.
• Debt Levels: Total borrowings increased by approximately $94 million compared to the prior year-end position, with net financing activities providing $72.7 million in cash.

Outlook, Risks, and Contingencies

Dividends: The Board proposed an annual dividend of $0.34 per share ($0.68 per ADS), totaling approximately $401 million. This includes an interim dividend already paid. A remaining dividend of $0.21 per share is expected to be paid in June 2011 pending shareholder approval.

Legal and Regulatory Risks:

• Venezuela Nationalization: The Company continues to face the nationalization of its Venezuelan subsidiaries (Tavsa, Matesi, and Comsigua). Operations were assumed by the Venezuelan government in 2009. Tenaris has ceased consolidating these entities and classifies the investments as available-for-sale financial assets. The Company maintains net receivables of $27.7 million from these entities and reserves rights to pursue international arbitration.
• Investigation: The Company is voluntarily cooperating with the SEC and DOJ regarding an investigation into sales agency payments in Central Asia that may have improperly benefited customer employees. The outcome is pending and unpredictable.
• Tax Contingency: An Argentine tax assessment regarding tax loss carry-forwards represents an estimated contingency of approximately $24.6 million. Tenaris believes an obligation is not probable and has not recorded a provision.

Commitments: The Company has significant raw material purchase commitments, including a contract with Nucor Corporation estimated at $721.0 million and a contract with Rio Tinto Fer et Titane estimated at $217.8 million.

Investor Verification Checklist

• Verify the impact of the $392.9 million working capital outflow on future liquidity and operating cash flow sustainability.
• Monitor the status of the SEC/DOJ investigation regarding Central Asia sales agency payments for potential fines or reputational damage.
• Assess the resolution timeline and potential recovery value regarding the nationalized Venezuelan assets and the $27.7 million receivable.
• Confirm the approval of the proposed $0.34 per share annual dividend at the June 1, 2011 shareholder meeting.
• Review the execution of capital expenditure plans ($210.6M in Q1) to ensure alignment with long-term growth strategies.
