Tenaris has been busy pouring money into pipes and plants, from new OCTG grades in Canada to insulation capacity in Nigeria and fresh service hubs for offshore projects. Investors who held Tenaris from the start of the year are up 70.3%, including dividends. If you were deciding whether to buy on 2026-01-01, what would you have needed to believe about these contracts, tariffs and capacity moves to view that risk as acceptable?
This theme extends beyond Tenaris. See which of 43 power grid technology and infrastructure stocks may still merit a closer look.
The Two Stories Investors Had To Choose Between On Tenaris
The shares cost €16.38 at the start of the period, and anyone weighing Tenaris then was really choosing between two believable stories about its future.
On the upbeat side, the December 2025 bull view saw a Fair Value of €17.58. This was described as the price implied if modest 1.3% annual revenue growth and a future P/E of 10.9x occurred alongside a 14.7% profit margin.
The more cautious December 2025 argument pointed to a Fair Value of €13.31. This was based on revenue declining 3.6% a year and profit margins easing to 12.5% as energy transition and competition weighed on demand.
What The Evidence Did To The Tenaris Argument
Tenaris moving ahead with domestic TN 95EY production in Ontario, plus a US$10m thermal insulation plant in Nigeria and a new Suriname service center, supported the case that capacity, premium grades, and local service would matter. Q3 2026 results also showed higher revenue, higher profit, and a net margin of 16.4% versus 15.0%, which aligned with that view.
Tariffs on dumped steel and CEO succession gave the cautious story some weight. The lesson is simple: when a thesis hinges on capacity, pricing power, or mix, track reported revenue, profit, and margin side by side with each announced project.
What Tenaris's Run Up 70% Already Assumes
Tenaris trades at €27.49 after a 70.3% gain from the start of the year. The bearish analyst Narrative on Simply Wall St sees its Fair Value below that level, framing the current quote as already pricing in healthy cash generation and capital returns.
The same Narrative leans on a single question: can heavy spending on localized, higher spec capacity turn into durable volumes and margins while shipment timing, logistics costs and a larger fixed cost base keep pulling at earnings?
"The main thing that has to go right is that Tenaris converts its heavy spending on localized capacity expansions and higher spec products into stable volumes and margins, despite ongoing logistics issues, tariffs and postponed Middle East shipments. The numbers imply that Tenaris’s current share price already bakes in continued strong cash generation and high capital returns, even as recent quarters show softer sales, lower EBITDA and higher structural cost headwinds, which leaves limited room for disappointment."

Looking One Step Beyond Tenaris
Tenaris focuses on tubular steel and the projects that depend on it. You could also consider where the hydrocarbons inside those pipes originate.
Large fields and gas basins still need someone to find, lift and sell the molecules. One sizeable producer is investing in automated drilling and tightly managed fields.
It is also adding gas liquefaction capacity and transport routes. That can turn underground resources into contracted cargoes moving worldwide.
A growing side arm captures and stores emissions for industrial clients on service style terms. If that mix shifts further toward fee based work, the earnings profile may diverge from a traditional oil and gas group.
