Tenaris (TS) Q4 2025 earnings review
Defying Gravity: Margins Hold Despite Tariff Shock
Tenaris delivered a resilient Q4, absorbing the full impact of the 50% U.S. Section 232 tariffs without the feared margin collapse. Revenue grew 5% YoY to $3.0B, defying a lower global rig count, while EBITDA margin compressed only slightly to 23.9% (from 25.3% in Q3). The standout story is the 'Others' segment, which surged 51% sequentially as fracking resumed in Argentina. While North America remains the fortress (+29% YoY), weakness in South America and a collapse in Europe (-45% YoY) highlight significant regional divergence. Management's guidance for Q1 2026 is stable, suggesting the worst of the tariff transition is managed.
🐂 Bull Case
Sales in North America grew 29% YoY despite falling rig counts. Tenaris is leveraging its domestic production and 'Rig Direct' service model to decouple from pure activity metrics, proving it can maintain pricing power even as competitors struggle.
The 'Others' segment (services) grew 51% QoQ driven by resumed fracking in Argentina. With $4B in new financing for Vaca Muerta infrastructure, this high-margin service business is entering a new growth phase.
🐻 Bear Case
EBITDA margins compressed 140bps sequentially. While better than feared, the 50% tariff on steel inputs is a structural headwind. Management admits pricing recovery (Pipe Logix) lags cost increases, potentially squeezing H1 2026 margins further if U.S. prices don't rise.
Europe revenues cratered 45% YoY ($341M to $187M). While partly project-timing related, such a steep decline indicates structural weakness in industrial and mechanical pipe demand outside of oil & gas.
⚖️ Verdict: 🟢
Bullish. Tenaris proved its fortress balance sheet ($3.3B net cash) and operational flexibility can weather a 50% tariff hike with minimal damage. The Argentina restart provides a new catalyst to offset North American stagnation.
Key Themes
Argentina 'Others' Segment Breakout
A specific, operational inflection point occurred in Argentina. The 'Others' segment (primarily oilfield services/fracking) exploded 51% sequentially to $156M. This confirms the restart of Vaca Muerta activity after a political lull. With a third frac fleet deploying and $4B in industry financing secured, this segment is transitioning from a drag to a growth engine.
Tariff Margin Squeeze
The full impact of U.S. Section 232 tariffs (50%) hit in Q4. While management mitigated this via the Koppel steel shop restart, margins still fell 140bps QoQ to 23.9%. The concern is the lag: Hot-Rolled Coil (input) costs are up, but Welded Pipe prices (output) are suppressed by imports. Until U.S. pipe prices react to the tariff wall, margins remain vulnerable.
Offshore Super-Cycle Visibility
Deepwater remains a bright spot. Management highlighted specific project wins including Shell's Sparta (20K psi), Exxon Guyana, and TotalEnergies GranMorgu (Suriname). Revenue from offshore in H1 2026 is expected to exceed H2 2025. This high-spec mix shift defends ASPs against onshore weakness.
Regional Divergence: Europe & South America
While North America held flat QoQ, the international portfolio showed cracks. Europe fell 45% YoY and South America dropped 16% YoY (due to pipeline completion). The reliance on North America (now ~51% of total sales vs ~42% a year ago) is increasing, raising concentration risk.
Capital Allocation Discipline
Despite headwinds, cash generation remains robust ($665M FCF in Q4). Management spent $537M on buybacks in Q4 alone and raised the dividend 7%. With $3.3B in net cash, the capacity for M&A or accelerated buybacks provides a high floor for the stock.
Other KPIs
Stable. Flat QoQ but up 29% YoY. This demonstrates the 'Rig Direct' model's ability to decouple from the rig count. The region now accounts for 51% of total company sales.
Strong but declining slightly from $3.6B a year ago, primarily due to aggressive shareholder returns ($1.36B buybacks + $900M dividends in FY25) rather than operational weakness.
Stable. Despite raw material volatility and tariff pressures, pricing discipline held. Management expects stability to continue in Q1 2026.
Guidance
Stable. Implies revenue ~$3.0B and EBITDA margin ~24%. Management sees no disruptors in the immediate term, signaling that the tariff shock has been absorbed into the baseline.
Improving. Management expects the IFRS impact of tariffs to decrease in Q1 compared to Q4 as they optimize the supply chain (e.g., Koppel steel shop ramp-up). This is a subtle margin tailwind.
Stable. Expecting an increase in Q1 (receivables) followed by stabilization. No major cash release expected from inventory this year.
Key Questions
Pipe Logix vs. Cost Lag
Hot-rolled coil prices are rising, but welded pipe prices are stagnant due to imports. How many quarters of margin compression can we expect before U.S. market prices actually reflect the higher input costs?
Europe's Structural Health
Europe sales collapsed 45% YoY. Is this purely project timing (line pipe), or a de-industrialization signal from the region? When does this segment bottom?
Use of the $3.3B War Chest
With consolidation slowing in the U.S., where is the next M&A target? Or should investors expect the buyback pace (>$1B/year) to become the permanent use of cash?
